Weekly Outlook August 29-September 5, 2016

In a lot of ways, this week will be very similar to last week. That shouldn’t be a big surprise, we’ve been stuck in the same weather pattern for nearly the entire summer.

These are called windshield wipers. You use them to clean the rain off of your windshield. Most of you probably haven’t used them much in the past few months.

Just like last week, we’ll start the week off with a cold front crossing the region early Monday. It may produce a few showers early this morning, but that’s about it. High pressure briefly builds in for Tuesday with drier conditions, then another cold front moves through on Wednesday. It may produce a few showers or thunderstorms late Wednesday. After that, high pressure builds in for the rest of the week and into the Labor Day Weekend with cooler and drier conditions. Dewpoints will likely be in the 40s again from Thursday into Saturday.

That large high pressure area building in will also be a “deflector shield” of sorts. There are currently three tropical systems in the Atlantic, and two of them, are not far from the US mainland. First we have Major Hurricane Gaston. Gaston has maximum sustained winds near 120 mph, making it a Category 3 Hurricane on the Saffir-Simpson Scale. Gaston is centered about 575 miles east of Bermuda tonight. Unless you’re in the middle of a Trans-Atlantic cruise, then you don’t have to worry about Gaston, as it will be heading out over the open Atlantic, no threat to any land areas. Gaston will start to send some rough seas our way though, so if you are planning on heading to the beach this week, be alert, as there will be a higher than now risk for riptides.

Closer to home, Tropical Depression Eight developed on Sunday. TD 8 has top winds near 35 mph, and is centered about 285 miles southeast of North Carolina. The forecast calls for TD 8 to strengthen into a tropical storm late Monday. Since it is expected to turn towards the northwest, a tropical storm watch has been issued for the Outer Banks of North Carolina from Cape Lookout to Oregon Inlet. After brushing the Outer Banks late Tuesday, it will turn more towards the north and northeast, merging with the cold front that will cross our region on Wednesday.

We also have Tropical Depression Nine, centered about 100 miles southwest of Key West, Florida and just off the north coast of Cuba tonight. This is the system that has been relentlessly hyped by many in the media and on the Internet (but not this site) for the past week plus as the next “Storm of the Century”. It finally developed a circulation center Sunday afternoon, and was deemed a tropical depression. If you believed many of the computer models and “Facebook Forecasters” earlier in the week, it was supposed to hit south Florida as a hurricane yesterday. Right now, it looks like the storm should turn more to the north while strengthening into a tropical storm over the next day or two. A track towards the Big Bend of Florida seems most likely at this point, but as this storm has shown already, it will do (or not do) what it wants to. Assuming it does track towards Florida, it should cross the Southeast, then emerge off the coast of Georgia or northeastern Florida. Once there, it will move over the warm waters of the Gulf Stream and could strengthen once again. However, with a big high pressure area to the north (we told you that we’d tie that in eventually), a track up the coast is unlikely. Instead, the system will likely head out into the open Atlantic.

Weekly Outlook August 22-28, 2016

As we start off the last full week of meteorological summer, some things will remain the same as they have for months – there will be very little rainfall, worsening an already severe drought across the region. Some things will change though – humidity levels will drop at least for a few days and so will temperatures.

The week will start off with a little rain. However, by the time most of you read this, the rain will already have ended. A cold front will cross the region early Monday morning with showers and possibly thunderstorms. The rain should end towards daybreak, then skies will quickly clear out as the front pushes offshore. After that, high pressure builds in, with much drier air for Monday and Tuesday. How dry? How does dewponts in the 40s sound?  Temperatures will actually be near or a little below normal as well. By Wednesday, the high moves offshore, winds become southwesterly, and both the temperature and humidity start to rise again. On Friday, another cold front sweeps across the region, with a few showers and thunderstorms expected. Cooler and drier air returns next weekend.

Just in case you forgot, this is called an umbrella. You use it to keep yourself dry when it rains. Most of you probably haven’t seen one for months.

Monday: Showers ending around daybreak, then becoming partly to mostly sunny, breezy, and less humid. High 76-83.

Monday night: Clear skies. Low 53-60.

Tuesday: Wall-to-wall sunshine. High 75-82.

Tuesday night: Clear skies. Low 54-61.

Wednesday: Sunshine and a few clouds. High 83-90.

Thursday: Partly to mostly sunny. High 82-89.

Friday: A mix of sun and clouds with afternoon showers and thunderstorms possible. High 83-90.

Saturday: Mostly sunny. High 79-86.

Sunday: Partly to mostly sunny. High 77-84.

As this post is being written, Typhoon 10W (Mindulle) is making landfall very close to Tokyo. That’s probably not good. If you’re looking for an update on the massive hurricane that’s supposed to wipe out the East Coast just before Labor Day, then you’re out of luck. because it’s a fantasy that will not likely happen. Oh, we’ve got plenty of activity – Tropical Depression Fiona is dying southeast of Bermuda. There are two other areas we’re watching, one of which could become a tropical depression on Monday. The odds of either of those impacting the East Coast are still fairly small though. If there is a potential threat, we’ll let you know all about it.

Weekly Outlook August 15-21, 2016

Cold fronts and warm fronts commonly pass through our area every few days during most of the year, except in the summer. During the summer, since the jet stream is usually fairly far to the north, we may see a frontal passage once a week, sometimes even less frequently. This week, that will not be the case. We’re going to have several frontal passages. Oh, it’ll be the same front the first few times, but it’ll come through several times.

By now, you’re probably pretty confused, so we’ll explain. Late on Sunday, we had a cold front move across the region. As high pressure builds in behind it, drier weather will settle in on Monday. Meanwhile, that front will stall out to our south. As the high slides offshore, southerly winds around the high will send that front back northward, this time as a warm front. as a result, the humidity will return on Tuesday. Some showers and thunderstorms will likely accompany the warm front. A wave of low pressure will then ride along this front on Wednesday, which will send it back across the region, this time as a cold front (again). At this point, we’re probably done with that front, but wait, there’s another one coming! That one will also be a cold front. It may trigger a few showers and thunderstorms late Thursday or early Friday before it moves through.That front will most likely stall out to our south, but for now at least, it doesn’t look like it comes back this way. Instead, high pressure builds in for next weekend, with cooler conditions, thanks to easterly winds off the Atlantic. So, to recap, one front comes through three times, and a second one comes through one. Got it? Good. (Just be glad we didn’t have any occluded fronts to deal with.)

Monday: Partly to mostly sunny and less humid. High 84-91.

Monday night: Partly cloudy. Low 64-71.

Tuesday: A mix of sun and clouds, humid, chance for showers and thunderstorms, especially in the afternoon. High 81-88.

Tuesday night: Partly to mostly cloudy, a few lingering showers and storms, mainly in the evening. Low 68-75.

Wednesday: Partly sunny, slight chance for a shower or thunderstorm. High 80-87.

Thursday: A mix of sun and clouds. High 83-90.

Friday: Partly sunny, chance for showers and thunderstorms. High 80-87.

Saturday: Intervals of clouds and sunshine with a chance for showers. High 77-84.

Sunday: More clouds than sunshine, a shower or two is possible. High 76-83.

Weekly Outlook August 8-14, 2016

Looks like we’ve got a typical summer-time week on our hands. Warm temperatures, increasing humidity, late-day showers and thunderstorms – they’re all in the forecast.

We start the week with high pressure building in from the Great Lakes. That gives us sunshine, warm temperatures, and low humidity for Monday and Tuesday. By Wednesday, the high slides offshore. This allows winds to become southwesterly, bringing even warmer weather in, but also more humidity. With the humidity will also come an increased risk of afternoon showers and thunderstorms, especially Thursday and Friday. By the end of the week a front will start to approach from the north.This will give us an even better chance of showers and thunderstorms next weekend, but right now, neither day looks likely a washout. Cooler and drier weather is likely behind the front, but when that front moves through is a big question mark. One model wants to wait until Monday, with Sunday being hot and humid once again, while another brings it through early Sunday, with significant cooler temperatures Sunday afternoon. For now, we’ll go in between the two, because frankly, we’re not sure which way to lean at this point.

Saturday: Partly sunny, chance for afternoon showers and thunderstorms. High 88-95.

Sunday: More clouds than sunshine with a chance for more showers and thunderstorms. High 80-87.

Weekly Outlook August 1-7, 2016

August has arrived, and typically, this means the “Dog Days of Summer”. The next few days though will not feel like that around here. Oh sure, heat could make a comeback late in the week, but even then, it will be short-lived.

nws_precip_boston_mtd

After one of the driest Julys on record across the region, we’re going to start August off with some rainfall. Oh, it won’t be a lot, in fact, it’ll probably be precious little in many places, but right now, we need all that we can get. A frontal system is stalled out south of the region, and a wave of low pressure will ride along it. This will give us clouds, cool temperatures, and some showers for Monday and early Tuesday. Once the wave moves by, high pressure builds in, with drier weather for much of the remainder of the week. Temperatures will trend upwards once again, with some 90-degree readings possible late in the week. By Saturday, another cold front will be coming through, with showers and thunderstorms possible. High pressure brings drier weather again for the end of the weekend.

The other thing that August is known for is the tropics getting more active. We’ll get into more details on that with a blog post in another day or two, but currently we have a typhoon heading directly toward Hong Kong and a Tropical Depression in the Eastern Pacific. We are also watching a system in the Bay of Bengal that could threaten India, another system southwest of Mexico, and a system moving across the Caribbean. The latter one could threaten the Yucatan or Central America later this week.

Weekly Outlook July 25-31, 2016

How many of you enjoyed the heat and humidity last week? You’re in luck! We’ve got more coming! How many of you enjoyed the severe weather last week? Guess what? There’s more of that coming too! Yup, it’s another summer week here in New England.

 

We start off with Monday, which will be hot and humid after a warm front crosses the region. As a cold front start to approach from the northwest later in the day, it will likely trigger thunderstorms across the region. Some of these storms could be strong to severe, so if you’re planning to be outside late in the day, keep an eye to the sky. The front moves through and then Tuesday is much drier, but still hot. High pressure keeps it hot on Wednesday too.Another front comes through on Thursday, with some additional showers and thunderstorms possible. After that, things get tricky. The front stalls out south of New England and a wave of low pressure rides along it, likely giving us some additional showers and thunderstorms on Friday. The big question is next weekend. Does another wave of low pressure ride along the front, giving is more showers along with cooler conditions, or does high pressure build in, pushing the front farther to the south? We’ll be optimistic for now, and go with high pressure building in, but keep in mind that this could change.

Friday: More clouds than sunshine with additional showers and thunderstorms, especially south of Boston. High 79-86.

Saturday: Partly to mostly sunny.High 77-84.

Sunday: A mix of sun and clouds. High 76-83.

Weekly Outlook July 18-24, 2016

The upcoming week can be described fairly easily. We’ll start off hot, cool off just a bit, gradually get hot again, and then get REALLY hot next weekend. oh sure, there might be a few thunderstorms on Monday, again on Friday, and possibly next Sunday, but the key word there is few. As in, don’t count on getting one to cool you off. And certainly don’t count on helping alleviate the drought any time soon.

hires_hindex_boston_20
Heat Index forecast for 3pm Monday from the NAM model. Image provided by WeatherBell.

A cold front will cross the region today. Before it does though, with plenty of sunshine, temperatures will jump into the lower to middle 90s. When you factor in the humidity, the heat index will be in the middle to upper 90s across the region. As a cold front slices through this airmass in the afternoon, it will trigger showers and thunderstorms, some of which could be strong to severe. As is usually the case, the best chance for severe weather will be north and west of Boston. As the line of storms gets closer to the coastline, it will likely start to fall apart. High pressure then builds in for Tuesday, with cooler air behind the front. However, as the high moves offshore, south to southwest winds will allow temperatures to gradually warm up as the week goes on, with highs getting back into the 90s by late in the week. Another front will approach the region on Friday with another chance for showers and thunderstorms. After that, many of the models are indicating the possibility that the weekend, especially Sunday, could be hot. When we say “hot”, we mean “HOT”, as in, there is a chance that the high temperature in some places might be include a 3rd digit and begin with the number 1. Several of the models have been showing a signal for hot weather next weekend, but as always, timing is everything. Another front will be approaching the region, with the possibility of more showers and thunderstorms. Not only will the timing of the front be a big factor in the development of showers and storms, but it will also have an impact on how hot it gets. We should have more clarity on that as the weekend gets closer.

Monday: A sunny start, then clouds move in with showers and thunderstorms developing in the afternoon. Some of the storms could be strong to severe, with strong winds, hail, torrential downpours, and possibly even a tornado. High 88-95.

Monday night: Showers and thunderstorms taper off in the evening, followed by clearing skies. Low 63-70.

Tuesday: Sunshine and a few clouds. High 77-84.

Tuesday night: Mostly clear. Low 54-61.

Wednesday:Mostly sunny. High 77-84.

Thursday: Sunshine and some afternoon clouds. High 83-90.

Friday: Partly sunny, chance for showers and thunderstorms. Humid. High 88-95.

Saturday: A mix of sun and clouds. High 89-96.

Sunday: Partly sunny, chance for showers and thunderstorms. Humid. High 92-99.

Weekly Outlook July 11-17, 2016

Since summer tends to be much shorter around here than in other parts of the country, we tend to cherish our summer weekends. Firing up the grill, heading to the pool/beach, or just some general outdoor activities are common. So when we get a weekend in July like the one we just had, with plenty of cloudcover, showers, and temperatures holding in the 60s, it makes it feel even worse than it really is. The good news is that now that the weekend is over, things will improve! High pressure will build in, with sunshine and warm temperatures returning. In fact, it will get hot and humid later in the week, with temperatures likely soaring past 90 degrees across much of the region.

Cruise 2015 711
Maybe the fog wasn’t quite this thick, but it wasn’t a great weekend.

What about next weekend? Well, that might be a bit up in the air. We’re hoping for nice weather, but at this point, we can’t guarantee it. One model says that Saturday might be a washout. However, even the previous run of this model showed a nice day for Saturday, so we’re inclined to lean towards that instead. Remember though, several models showed a week ago that this past weekend was going to be sunny and hot. This is why forecasts beyond 5 days can be very tricky sometimes.

Monday: A mix of sunshine and clouds, slight chance for a popup shower. High 74-81.

Monday night: Becoming mostly clear. Low 56-63.

Tuesday: Partly to mostly sunny. High 81-88.

Tuesday night: Clear to partly cloudy. Low 61-68.

Wednesday: Sunshine and some afternoon clouds. A few showers and thunderstorms may develop. Becoming humid. High 86-93.

Thursday: Partly sunny. Humid. High 85-92.

Friday: A mix of sun and clouds, chance for a few showers and thunderstorms. Hot and humid with a high of 88-95.

Saturday: A mix of sun and clouds. A shower or thunderstorm can’t be ruled out at this point. High 82-89.

Sunday: Partly to mostly sunny. High 81-88.

2015Fair 191
Happy Fourth of July from Storm HQ!

 

A few days ago, some of the models were starting to indicate that a prolonged period of hot weather was heading out way for the latter half of this week and into the following week. Well, the models have changed their tune, and it doesn’t look like we’re going to have several days in the upper 90s to lower 100s now. Oh there will still be a couple of warm to hot days, but not many.The other thing the past few months have been lacking is rainfall, and it’s starting to become a problem. There is some in the forecast, but not a lot. We really need a lot, though not at once, as that would create other problems. Overall though, if you’re on vacation this week, things will be pretty nice.

We start the week with a fantastic holiday – sunshine and warm temperatures. Perfect for a cookout, heading to the beach/lake/pool, shooting off fireworks, or all of the above. Tuesday looks “iffy” right now. A system will pass south of New England, but how far south is still up in their air. Some showers and thunderstorms are certainly possible, especially south of Boston. The farther north you go, the more likely you’ll stay dry. High pressure returns on Wednesday, then things get “iffy” again. A series of disturbances will move along the jet stream and across New England for the end of the week and the weekend. Timing these storms isn’t easy, and while our forecast will reflect the uncertainty with a chance of showers and thunderstorms each day, for the most part, things will be good, with none of the days being a washout.

Independence Day: Plenty of sunshine, fading behind some late-day high clouds. High 82-89.

Tonight: Becoming mostly cloudy, chance of showers towards morning, mainly south of Boston. Low 59-66.

Tuesday: Mostly cloudy with showers and a few thunderstorms possible, especially south of Boston. High 80-87.

Tuesday night: Clearing skies.Low 61-68.

Wednesday: Partly to mostly sunny.High 88-95.

Thursday: A mix of sun and clouds, chance for afternoon showers and thunderstorms, mainly north and west of Boston. High 85-92.

Friday: Partly sunny, chance for a few showers and thunderstorms. High 78-85, coolest along the coast.

Saturday: Intervals of clouds and sunshine with a chance for showers and thunderstorms. High 77-84..

Sunday: Partly sunny with a chance for showers and thunderstorms. High 80-87.

Weekly Outlook June 27-July 4, 2016

Here we are, approaching the Fourth of July, and we still haven’t had much heat and humidity. Will that change over the next week? Yes and no. We’ll have a little bit more humidity over the next few days as a cold front starts to approach from the west. The front will take its time moving through, so we can expect showers and a few thunderstorms for Tuesday and possibly into Wednesday. Neither day will be a washout, but we really need the rain. The lack of rainfall across New England recently has led to drought conditions expanding across the area.

Once the front finally moves through on Wednesday, high pressure will build in for Thursday with drier weather, but temperatures will warm back up into the 80s. Another front may bring in some showers late Friday, but again, the day shouldn’t be a washout. After that, high pressure builds back in for the holiday weekend, with sunshine and seasonably mild conditions.

What about the heat? Any of that coming? The answer is “maybe”. The latest outlook for next week from the National Weather Service is calling for near to below normal temperatures.

Latest 8-14 day temperature outlook from the Climate Prediction Center, valid for July 4-10, 2016.

However, the most recent run of the GFS model is painting a different picture, especially for the end of that period. While we rarely put much stock in most computer models beyond 5-7 days at most, we were rather shocked at the picture the GFS is painting for the following weekend. If you take it literally (which is NEVER a good idea), the model is predicting record heat for parts of the region. While we don’t like to forecast out that far, temperatures closer to normal (upper 70s to lower 80s), seem more likely to us than what the GFS is trying to sell.
