Astronomical Winter begins at 10:03am Sunday, but until then, Mother Nature can’t decide which season we’ll get to experience.

A low pressure system that prompted blizzard warnings in the Dakotas today will quickly move into southeastern Canada by tomorrow. Don’t worry, we’re not expecting blizzard conditions around here, but some heavy rain and strong winds are a lot more likely. With the system passing to our north, we’ll be in the warm side, and southwest to southerly winds will increase ahead of a cold front trailing the system. As the clouds move in later today and tonight the increasing winds will allow temperatures to rise for much of the night, climbing well into the 50s. The rain moves in after midnight, and it could be briefly heavy Friday morning. South winds of 20-30 mph, gusting to 50 mph at times will bring in unseasonably warm air, with some places possibly reaching 60. The cold front comes marching through around midday, quickly bringing an end to the rain. As winds shift into the west they will diminish a little, but will also usher much cooler air in, with temperatures quickly dropping into the 40s and 30s by evening. There could be a few rain or snow showers as the colder air rushes in, but for the most part, once the front moves through we’ll dry out. The gusty winds will also help to dry out the roads, so black ice shouldn’t be a problem Friday night and early Saturday, but you should probably use some caution if you’re heading out.

Wind gusts of 40-50 mph are expected on Friday, a little stronger on Cape Cod. Image provided by WeatherBell.

We’ll clear out and turn colder for Friday night and Saturday, but clouds quickly stream back in Saturday afternoon and evening. Another weak system passes by to our north, but it doesn’t look like it’ll be accompanied by much, if any precipitation Saturday night and Sunday. It will bring in some milder weather once again, as temperatures get back into the 40s Sunday afternoon. Skies clear out behind that system later Sunday, with gusty west winds bringing cooler air back in for Sunday night and Monday as high pressure builds back in.

Temperatures Saturday morning will be 25-35 degrees colder than they were at the same time Friday morning. Image provided by WeatherBell.

Thursday night: Becoming mostly cloudy and breezy with rain developing after midnight. Low 33-40 during the evening, temperatures rise overnight.

Friday: Cloudy and windy with rain, possibly heavy in the morning, ending in the afternoon. High 52-59, temperatures start dropping quickly in the afternoon.

Friday night: Chance for a few rain or snow showers during the evening, gradual clearing overnight, breezy. Low 22-29.

Saturday: Sunny in the morning, clouds return in the afternoon. High 35-42.

Saturday night: Plenty of clouds, becoming breezy. Low 28-35 during the evening, temperatures hold steady or rise a little overnight.

Sunday: Becoming partly sunny and breezy. High 41-48.

Sunday night: Partly cloudy, breezy, colder. Low 18-25.

Monday: Mostly sunny, breezy in the morning. High 26-33.

Astronomical winter starts next Sunday, but leading up to it we’re going to have some days that are decidedly un-winterlike.

Highs in the 50s on Friday? It’s possible. Image provided by weathermodels.com

The storm that brought us the snow yesterday continues to pull away today with windy and chilly conditions in its wake today. A weak upper-level disturbance will bring in some clouds this afternoon and evening, but moisture will be limited, so aside from a few stray flurries, we’ll remain dry. The high slides off to our south for Tuesday into Wednesday, keeping us dry, but allowing temperatures to moderate. as we get to the latter half of the work week things start to change. A low pressure system heads into southern Canada, with gusty southwest winds ahead of it bringing milder air in on Thursday, with many places likely getting into the 40s. Windy and mild conditions are likely for Thursday night into Friday along with some rain as the system moves across the region. Some models show the potential for some heavy rain, which will not only melt the snow, but likely help a little with the drought conditions the persist in parts of the region. We’ll have more details on the potential for strong winds and heavy rain in our Weekend Outlook on Thursday. Temperatures drop quickly behind the cold front on Friday, with much colder air moving back in for Friday night and Saturday. For Sunday, astronomical winter begins with the solstice at 10:03am, but indications now are for a milder day with some rain possible ahead of another cold front.

Monday: Sunny in the morning, clouds move back in during the afternoon, breezy. High 21-28.

Monday night: Mostly cloudy, chance for a few flurries near the South Coast, skies start to clear out late at night. Low 13-20.

Tuesday: Partly to mostly sunny, clouds start to filter back in late in the day. High 28-35.

Tuesday night: Partly to mostly cloudy. Low 19-26, temperatures may start to rise after midnight.

Wednesday: Partly sunny, breezy. High 39-46.

Wednesday night: Partly cloudy. Low 22-29.

Thursday: Becoming mostly cloudy. High 42-49.

Thursday night: Cloudy and windy with rain developing. Low 34-41 during the evening, temperatures rise overnight.

Friday: Rain likely during the morning, possibly changing to snow before ending across the interior, skies start to clear out in the afternoon, windy. High 48-55 in the morning, temperatures drop during the afternoon.

Saturday: Partly sunny. High 32-39.

Sunday: Intervals of clouds and sun, chance for a few showers. High 40-47.

Snow Kidding, a White Sunday is on the Way

If you live in the Merrimack Valley, and points north and west, you already saw your first snowstorm of the season a little more than a week ago. The rest of us get that experience Sunday morning.

Areas well north and west of Boston got their first snowstorm about 10 days ago. Image provided by Weathermodels.com

A complex low pressure system is going to impact much of Southern New England for a good chunk of Sunday, including the Patriots/Bills game in Foxborough. An upper level disturbance is moving across Ontario this evening while a surface low pressure system takes shape over the Mid-Atlantic states. If conditions were a little more favorable, this could become a blockbuster snowstorm, but that won’t be the case here. We’re already seeing a little rain developing across parts of the Mid-Atlantic, including the New York City area, but as the system moves off the Virginia coastline overnight and strengthens colder air will move in, changing the precipitation over to snow. We should see snow spreading across our area a little after midnight, though it will probably be mixed with rain across parts of Cape Cod and the Islands to start. Snow showers and some periods of steady light snow are expected for the rest of the overnight and into Sunday morning. The bulk of the snow will be found south of the Mass Pike, with just some snow showers to the north, though the latest models are showing a little bit more snow to the north of Boston as well, as the system is coming in a little farther north. As the system starts to pull away by midday Sunday we’ll see the snow taper off, and gusty northwest to north winds will develop, ushering colder air in. Some ocean-effect snow may continue across parts of Cape Cod into the late afternoon or evening, but it should wind down at that point.

Snow moves in overnight, and ends Sunday afternoon/evening. Loop provided by WeatherBell.

This storm will not be that big of a deal for most of us, and shouldn’t have too much of an impact on the region, though if you’re heading to and from Foxborough there will be a bit more of an impact. If you’re arriving early to tailgate, expect to do it in the snow. As for the game, the snow should be winding down towards halftime, but for the 2nd half it’ll be windy and turning colder, so plan ahead for that it you’ll be sitting in the stands.

It might looks like this in Foxborough again Sunday morning. Image provided by the New England Patriots.

As for amounts, here’s what we’re thinking:

Central NH: Less than 1″
Southern NH/NH Seacoast/North Shore/Merrimack Valley: Around 1″
MetroWest/Metro Boston/Central MA: 1-2″
Northern RI/Northern portions of Plymouth/Bristol County (North of Route 44): 1-3″
Outer Cape Cod/Nantucket: 2-4″
Southern RI/Southern portions of Plymouth/Bristol County (South of Route 44)/Upper Cape Cod/Martha’s Vineyard: 3-5″

Snowfall amounts will be generally light to borderline moderate. Image provided by Weathermodels.com

You’ll have plenty of time to clean off the driveway after the snow is done, and you’ll want to do that at that point. With temperatures plunging into the teens for much of the region Sunday night, if you wait until Monday morning to clean off the driveway (or your car), it will be a lot more difficult.

That time has arrived. You know what we’re talking about. That S-word is in the forecast for part of the region. You know the one. It’s 4 letters and rhymes with blow.

Winter Storm Watches are in effect from Boston’s northern and western suburbs into Northern New England. Image provided by the National Weather Service office in Norton, MA.

The week starts off with high pressure giving us a breezy and cool Monday, but clouds move in Monday night, setting up a messy Tuesday. Despite the hype online for the past week, this will NOT be a big deal for a good chunk of the region, though it is the first one this season, so be prepared for lots of people that forgot how to drive in wintry weather (or never knew how to in the first place). That high will be moving off to the east, so while it’ll be chilly to start the day, we won’t have a lot of cold air in place for much of the storm. An upper-level disturbance will be moving in from the Great Lakes while low pressure develops off the Carolinas heading northeastward. These two won’t join forces until they are well past us, so a blockbuster snowstorm is not expected. In fact, this one will be moving fairly quickly, likely in and out in about 12 hours. We’ll see precipitation developing near or just after the morning rush hour. Temperatures should be cold enough for it to start as snow for most of the region, except for Southeastern Massachusetts, the Cape, and Islands. However, with the ocean still relatively mild (water temperatures are in the 40s to lower 50s), a quick change to rain is expected south and east of Interstate 95. How far inland that rain/snow line gets will be determined by the exact track that the developing coastal storm takes, but that is still a bit of a question mark at this point. Right now, we’re expecting the changeover to likely get as far inland as Interstate 495, but that is highly uncertain. Precipitation will fall moderate to heavy at times on Tuesday, especially south of Boston, but as the system pulls away from the region later in the day, colder air may allow the rain/snow line to quickly move back toward the coast, with much of the region possibly ending as some snow before midnight, except possibly the Cape and Islands. So, how much are we expecting?

Cape Cod/Islands: Rain
Southeastern MA/RI (South and east of I-95): A coating.
Boston-Providence (I-95 corridor): Less than 1″
Northern RI/MetroWest/North Shore: 1-3″
Merrimack Valley: 2-4″
Southern NH/NH Seacoast: 3-6″
Worcester Hills/Monadnocks/Central NH: 4-8″ (possibly 10″ in spots, especially in the higher elevations)

The Blend of Models is probably closest to our forecast for snowfall. Image provided by WeatherBell.

Once the system pulls away we turn drier and chilly for Wednesday as high pressure builds in. Another cold front moves through on Thursday, with a few snow showers or squalls likely accompanying it. Friday looks to be another dry and cold day as high pressure builds back in. The weekend looks unsettled at this point, but nothing significant. Another system will pass by to the south Saturday morning and afternoon with some snow showers inland and rain showers along the coast. At this point, any accumulations look to be light, but that can obviously change, so we’ll keep an eye on it as the week goes on. Another Alberta Clipper quickly follows for later on Sunday. For now, this one looks to be just a few rain showers, possibly snow or a wintry mix well inland, but again, a lot can change between now and then.

It’s going to get quite chilly behind a cold front Thursday night. Image provided by Weathermodels.com

Monday: Mostly sunny, breezy. High 36-43.

Monday night: Becoming partly to mostly cloudy. Low 20-27, milder across Cape Cod, temperatures start rising after midnight.

Tuesday: Cloudy with snow developing (rain Cape Cod and SE Mass), quickly changing to rain south and east of I-95, eventually changing to rain as far inland as I-495. High 32-39 north and west of I-95, 40-47 south and east, possibly warmer across Cape Cod.

Tuesday night: Rain changes back to snow before ending across much of the region, rain ending across Cape Cod, becoming breezy, especially along the coast. Skies start to clear out late at night. Low 23-30.

Wednesday: Sunshine and some afternoon clouds. High 33-40.

Wednesday night: Partly to mostly cloudy. Low 20-27.

Thursday: Intervals of clouds and sun, breezy, chance for a few snow showers or squalls. High 34-41.

Thursday night: Becoming clear, breezy during the evening, much colder. Low 7-14, warmer in urban areas and along the coast.

Friday: Mostly sunny in the morning, clouds start to filter in during the afternoon. High 23-30, a little milder across Cape Cod.

Saturday: Cloudy with a chance for snow showers inland, rain showers along the coast, mostly during the morning and early afternoon. High 34-41.

Sunday: Mostly cloudy, chance for a few afternoon rain showers, possibly mixed with snow or sleet at the start well north and west of Boston. High 34-41.

Despite the wet start to the weekend, drier weather is expected for much of the time.

A healthy drink of water tonight will help put a dent on the drought. Images provided by Pivotal Weather.

Low pressure moving up the Appalachians will bring some rain into the region this evening, possibly heavy at times for a while. As the system lifts northward, the rain will taper off and end from south to north before daybreak as temperatures rise thanks to increasing southwest winds. Temperatures may top 60 Friday morning in many areas before the storm drags a cold front across the region. Gusty west winds will usher cooler air in, with temperatures dropping through the afternoon. High pressure builds in for the weekend, but with an upper-level low moving through we’ll still have some clouds at times, and winds will remain gusty on Saturday. By Monday, we’ll see clouds start to move back in ahead of a fast-moving storm system moving out of the Great Lakes, with some showers possible at night.

Thursday night: Rain likely, possibly heavy for a while through the evening, ending before daybreak, breezy. Low 48-55.

Friday: Intervals of clouds and sunshine, windy. High 54-61 in the morning, temperatures drop in the afternoon.

Friday night: Partly cloudy, breezy. Low 39-46.

Saturday: Partly to mostly sunny, breezy. High 50-57.

Saturday night: Clear to partly cloudy. Low 31-38, a little milder across Cape Cod.

Sunday: A mix of sun and clouds. High 48-55.

Sunday night: Partly cloudy. Low 30-37, a little milder across Cape Cod.

Monday: Partly sunny. High 53-60.

Some unsettled weather is on the way for the 2nd half of the week for our region. Meanwhile, Jamaica is going to get walloped by Hurricane Melissa.

Wednesday could be a chilly, damp day for a good portion of the region. Image provided by Weathermodels.com

We start the week off with dry and cool conditions thanks to a large area of high pressure of eastern Canada. However, with an upper-level low still overhead we’ll see clouds popping up today with just a slight chance for a shower, mainly across Cape Cod where northerly winds could generate a few ocean-effect showers. As we head into Tuesday, low pressure will move off the Carolina coast and head out to sea well south of New England. However, the gradient between the developing low and the high to our north will result in northeast winds, bringing some moisture in from the Atlantic. This will result in some clouds, and possibly a few showers or some drizzle across eastern Massachusetts from late Tuesday into Wednesday.

The potential exists for more heavy rain at the end of the week. Images provided by Pivotal Weather.

By late Wednesday, we’ll start to watch a low pressure area developing in the Tennessee Valley. It should head northeastward, but there is still quite a bit of uncertainty with this system. We’ll likely see some rain move in from this system on Thursday, ending Friday morning, which would result in dry weather for trick-or-treating Friday evening. But that’s not the entire story. It’ll likely be rather breezy with this storm, taking down a lot of the remaining leaves on the trees. As a result, if we get enough rain, it’ll result in some slick roads with the wet leaves covering them, as well as areas of poor drainage flooding. But wait, there’s more! We’ll also be keeping an eye on what remains of Hurricane Melissa (more on that in a moment). The system should be heading well out to sea, but it could be just close enough to the East Coast for our developing system to tap into it, and infuse some tropical moisture, which would result in much heavier rain from this system. This scenario is not looking that likely at this time, but it is a possibility, so we felt the need to mention it. An upper-level low pressure area will then move in for the weekend with breezy and cooler conditions.

Forecast track for Hurricane Melissa. Image provided by the National Hurricane Center.

In the Caribbean, Hurricane Melissa is assaulting Jamaica and nearby portions of Cuba and Haiti, and this will continue for another day or two. As of 2am, Melissa was centered about 130 miles south-southwest of Kingston, Jamaica, drifting toward the west at 5 mph. Maximum sustained winds were near 150 mph, making Melissa a Category 4 storm. Unfortunately, the forecast for Jamaica is rather grim. Melissa will drift westward for another day or so, with some additional strengthening expected. That means rain and strong winds will continue to increase across Jamaica. By Monday night, the storm will start to turn more toward the north as a trough of low pressure off the Southeast begins to pick the storm up. That means it will likely cut right across the island, possibly as a Category 5 storm. In addition to sustained winds possibly in excess of 150 mph, a storm surge of up to 15-20 feet east of the center will likely result in widespread damage, including the capital city of Kingston. On top of that, rainfall totals of 20-40 inches (or higher) will result in catastrophic flooding and mudslides. Torrential rain and strong winds are also likely across portions of Haiti and eastern Cuba, especially as Melissa turns northward towards these areas. It will then cross the Turks and Caicos and parts of the Bahamas as it continues to slowly weaken. By mid-week, it could be a threat to Bermuda as well, possibly still at hurricane strength.

Rainfall totals of 20 to perhaps 40 or more inches are possible. Image provided by the Weather Prediction Center.

Monday: Morning sun with some afternoon clouds, slight chance for a shower or two, especially across Cape Cod. High 48-55.

Monday night: Clear skies north and west of Boston, partly to mostly cloudy south with a few showers or drizzle possible. Low 34-41, a little milder across Cape Cod.

Tuesday: Intervals of clouds and sun, breezy, chance for a few showers or some drizzle near the coast. High 49-56.

Tuesday night: Partly to mostly cloudy with some showers or drizzle around. Low 36-43, a little milder across southeastern Massachusetts and Cape Cod.

Wednesday: More clouds than sun, breezy, some additional showers or drizzle near the coast. High 49-56.

Wednesday night: Mostly cloudy, chance for a few showers. Low 38-45, a little milder across Cape Cod.

Thursday: Plenty of clouds, breezy, rain developing. High 54-61.

Thursday night: Periods of rain, breezy. Low 44-51.

Friday: Cloudy and breezy with rain ending. High 54-61.

Despite last week’s heavy rain, we’re still in a drought for much of the region and really need more rain. Well, we are going to get some today.

A cold front will produce showers and thunderstorms this morning as it moves through. Loop provided by Weathermodels.com

A strong cold front will cross the region this morning. Ahead of this front we can expect some heavy rain, maybe a rumble of thunder, and some gusty winds. While this could have some impacts on the morning commute, it will be short-lived, as the rain should end with the front moving offshore by early afternoon. Gusty west winds behind the front will send temperatures downward through the afternoon. We’ll clear out at night as high pressure builds in, giving us some sunshine on Tuesday, but clouds will quickly return Tuesday night ahead of another cold front. This one will produce more showers Wednesday morning, but it will also move through fairly quickly, with skies starting to clear out in the afternoon. High pressure then builds in with cooler weather for the end of the week, but with an upper-level low moving in, we’ll see some clouds each day, and possibly a few showers at times. The upper-level low lifts out over the weekend as high pressure moves overhead with dry and cool conditions.

Temperatures will be below normal for the end of the week and the weekend. Image provided by WeatherBell.

Monday: Rain likely during the morning, possibly heavy at times, ending from west to east by early afternoon, skies start to clear out late in the day, breezy, especially during the morning and early afternoon. High 60-67 in the morning, temperatures start falling in the afternoon.

Monday night: Becoming partly cloudy to clear with diminishing winds. Low 44-51.

Tuesday: Mostly sunny, some clouds start to move back in late in the day. High 58-65.

Tuesday night: Becoming mostly cloudy with showers developing before daybreak. Low 47-54, temperatures may rise a little overnight.

Wednesday: Showers likely during the morning, ending by early afternoon, followed by clearing late in the day, breezy. High 60-67.

Wednesday night: Clear to partly cloudy. Low 40-47.

Thursday: Sunshine and some afternoon clouds, a sprinkle is possible, breezy, cooler. High 54-61.

Thursday night: Clear to partly cloudy. Low 37-44.

Friday: A mix of sun and clouds, slight chance for a shower. High 52-59.

Saturday: Partly sunny. High 51-58.

Sunday: Partly sunny. High 52-59.

Some slow improvement is expected as the week goes on, but the start of the week will be rather nasty.

Low pressure will remain off the East Coast for much of the week. Loop provided by Tropical Tidbits.

Low pressure continues to meander around off the Mid-Atlantic coast today, with more rain, some of it heavy, strong winds, especially near the coast, and coastal flooding around the time of high tide, especially along east and northeast-facing coastlines. The low will start to drift eastward on Tuesday, with rain tapering off to showers and eventually ending, and winds slowly dying down, but it still won’t be a great day. By Wednesday the system will be south of Nova Scotia, but an upper-level low will move into the Northeast, keeping the clouds and cool temperatures around, with a few showers or some drizzle possible, especially near the coast, as north to northeast winds will remain gusty off the Atlantic. Thursday won’t be that much different than Wednesday as the upper low only slowly moves eastward.

Much of the region will pick up another 1-2″ (or more) of much needed rain before it ends. Images provided by Pivotal Weather.

We finally start to see some improvement by Friday as high pressure continues to build in at the surface, but also aloft. Saturday looks to be the pick of the week with sunshine and milder temperatures with high pressure in control. Sunday will be a warmer day, but we won’t see as much sunshine. Low pressure moving into the Great Lakes will send some clouds into the region. Whether we see any showers before the end of the day is still a question mark, but for now, it looks like most of the day should remain dry.

Temperatures could approach or exceed 70 on Sunday. Image provided by WeatherBell.

Monday: Windy with rain, heavy at times. High 51-58, a little milder across southeastern Massachusetts and Cape Cod.

Monday night: Breezy, rain tapers off to showers. Low 46-53, a little milder across southeastern Massachusetts and Cape Cod.

Tuesday: Cloudy and breezy with more showers, tapering off during the afternoon from west to east. High 55-62.

Tuesday night: Partly to mostly cloudy, showers ending in the evening in eastern areas, winds diminish. Low 45-52.

Wednesday: More clouds than sun, breezy, chance for a few showers or drizzle near the coast. High 58-65.

Wednesday night: Partly cloudy, breezy, a few showers are drizzle along the coast. Low 37-44.

Thursday: Intervals of clouds and sun, breezy, another shower or some drizzle possible near the coast. High 51-58.

Thursday night: Partly cloudy, breezy. Low 36-43.

Friday: Mostly sunny, breezy in the morning. High 55-62.

Saturday: Sunshine and some afternoon clouds. High 58-65.

Sunday: Partly sunny, showers possible late in the day. High 64-71.

We’ve had warm and dry weather for much of the past few months, but that is going to change this weekend.

Freeze Warnings (dark blue) and Frost Advisories (light blue) are in effect for much of the Northeast. Image provided by the National Weather Service.

A large area of high pressure will settle across the region tonight, bringing us clear skies and light winds – the ideal setup for radiational cooling. As a result, we’re looking at the coolest night so far this fall, with widespread frost away from the coast and urban areas, with a freeze expected in the normally colder locations. Friday will feature plenty of sunshine, but we’ll remain on the cool side. As the high starts to slide off to the south and east, winds will shift into the southwest Friday night, so we won’t be as chilly as tonight. Saturday should be a milder day, but we’ll see clouds starting to move in as moisture streams northward from a low pressure area developing off the Carolina coast. That system will drift northward Sunday and Monday, but won’t get this far north, though it will still have a significant impact on the region.

A developing low pressure will impact much of the East Coast this weekend. Loop provided by WeatherBell.

We’ll see rain spreading northward from the system, likely moving in from south to north Sunday afternoon and evening. How far north the rain gets is still a bit of a question mark, but it looks like most of the region should receive some much-needed rainfall. How much rainfall is also a question, but at this point it looks like the heaviest rain will be near the South Coast and also east-facing coastal areas, which some spots could see 1-2 inches of rain, possibly more, before everything starts to wind down on Tuesday.

Some models show the potential for very heavy rainfall with this system. Images provided by Pivotal Weather.

Rain isn’t the only impact from this system though. The pressure gradient between the developing low to the south and high pressure to the north will result in gusty east to northeast winds, especially near the coast, where some gusts in excess of 40 mph are possible, especially later Sunday into Monday. In addition, with tides still near the astronomical high for the month, persistent onshore gusty winds will result in some areas of coastal flooding, especially along east and northeast facing locations. Oh, and the combination of cloudcover, rainfall, and winds, will keep temperatures on the cool side again, especially on Monday.

Wind gusts in excess of 40 mph are possible, especially near the coast, Sunday night and Monday. Image provided by WeatherBell.

Thursday night: Clear and chilly. Low 29-36, milder along the coast and in urban areas.

Friday: Plenty of sunshine. High 56-63.

Friday night: Clear during the evening, some clouds start to filter in from south to north after midnight. Low 38-45, a little milder along the coast and in urban areas.

Saturday: Partly sunny, clouds start to thicken up late in the day. High 60-67.

Saturday night: Mostly cloudy. Low 44-51.

Sunday: Cloudy and becoming windy with rain developing from south to north. High 57-64.

Sunday night: Cloudy and windy with rain likely, possibly heavy at times. Low 48-55.

Monday: Cloudy and windy with more rain, possibly heavy at times. High 54-61, a little milder near the South Coast and Cape Cod.

Summer officially ends at the Autumnal Equinox at 2:19 this afternoon, but summer-like weather will continue beyond that.

Astronomical Fall begins with the Autumnal Equinox at 2:19pm today. Image provided by EarthSky.org

High pressure remains in control for today and part of Tuesday, keeping us dry, as has been the case for much of the summer. After a cool weekend, temperatures will start to moderate a bit today, but Tuesday will be rather warm and somewhat humid, with many locations likely topping 80. Clouds will start to move in during the day as a frontal system approaches the region. This will bring in some showers and possibly some thunderstorms late in the day and at night. As the front slows down, a wave of low pressure will ride along it on Wednesday, bringing in some additional showers along with much cooler temperatures. We do need the rain, and some models show the potential for some very beneficial amounts. However, for the most part, they have overestimated rainfall with several recent systems, plus there’s an old adage that usually holds true when talking about rainfall forecasts during a drought – “When in Drought, Leave it Out”. So, even though Wednesday will be a cool and damp day, it’s likely not going to be the widespread heavy rain that we need.

Temperatures could top 80 in many areas on Tuesday. Image provided by weathermodels.com.

High pressure builds in for Wednesday night and early Thursday with some drier air, but it won’t last long. An upper-level low pressure system and its surface reflection over the Great Lakes will start to slowly move into southeastern Canada toward the end of the week. The models are all over the place with the timing and strength of this system, but it looks like a second period of rainfall is expected possibly starting as early as Thursday afternoon, continuing into Friday night or possibly Saturday. Temperatures on Friday could be tricky. Several models show the system sending a warm front across the region, so even though we’re expecting more showers, temperatures could get well into the 70s. Of course, if the front gets hung up south of New England, temperatures may stay stuck in the 60s. We’re leaning towards the warmer scenario for now, but it is far from a lock. The system pulls away on Saturday then high pressure builds back in with drier air for Sunday.

Many models show the potential for a decent amount of rain between our two systems this week. Images provided by Pivotal Weather.

Monday: Partly to mostly sunny. High 68-75.

Monday night: Clear skies during the evening, becoming partly cloudy overnight. Low 54-61.
