Yup, we’re still stuck in the same pattern we’ve been in for a while now, with an upper-level low sitting near the Great Lakes. Some days will be like yesterday – wet (or very wet), and some will be like today (dry), but there’s no persistent heat on the way.

After an extraordinarily wet day on Sunday, we’ll dry out today as high pressure builds in. It’ll still be warm and humid, but we’re not expecting any rain. Another frontal system will move toward the region on Tuesday, with another round of showers and thunderstorms expected during the afternoon and evening. A few of these storms may produce downpours, but for now, we’re not expecting a repeat on Sunday. High pressure returns with drier weather on Wednesday, then another system brings in more showers and thunderstorms later Thursday into Friday. Again, some downpours are possible, but a widespread heavy rain event doesn’t appear likely at this time Once that system moves out, drier air should move in for the weekend. This would be a welcome change from the past several weekends, which all seemed to feature some rain, but don’t consider it a lock just yet. It’s a week away and things can change.
The rain this week shouldn’t be as heavy as Sunday was, but there is still the potential for some locally heavy downpours. Images provided by Pivotal Weather.
Monday: Becoming mostly sunny. High 83-90.
Monday night: Partly cloudy. Low 66-73.
Tuesday: Intervals of clouds and sun, showers and thunderstorms develop in the afternoon. High 82-89.
Tuesday night: Partly to mostly cloudy, showers and storms end before midnight. Low 65-72.
Wednesday: A mix of sun and clouds. High 80-87.
Thursday: Partly sunny, showers and thunderstorms move in late in the day, continuing at night. High 77-84.
Friday: Showers end in the morning, some clearing in the afternoon. High 77-84.
Another summer weekend, another upper-level low impacting our weather.
You’ve heard this from us plenty of times, but the pattern just hasn’t changed much. We’ve got a blocking pattern in place across Greenland, with a trough of low pressure, often times a closed low, setting up shop over the Midwest. These lows slowly drift eastward, and as they move out, we get a couple of nice days before the next trough/low drops into the Midwest. As disturbances rotate around those troughs, they help to trigger showers and thunderstorms, especially during the afternoon and evening hours. At least we’re on the warm side of the troughs, with southwest flow aloft, meaning it’s warm and humid most of the time. Consider yourselves lucky, in places on the other side of the trough, like the Northern and Central Plains, not only have the last few weeks been quite wet, temperatures have been well below normal.

In terms of what we can expect around here, well, expect some showers and thunderstorms to develop each day, mainly during the afternoon hours, and they should diminish after sunset. These storms will be most widespread on Friday and again on Sunday as disturbances rotate through the region. Any storms that develop may produce heavy rainfall, which could trigger flooding, especially with the ground quite wet across much of the region. Temperatures will be mainly in the upper 70s and 80s during the day, but it will remain humid.
Some locally heavy rainfall is possible over the next few days. Images provided by Pivotal Weather.
Thursday night: Partly to mostly cloudy, some showers and thunderstorms possible during the evening. Low 67-74.
Friday: Plenty of clouds, showers and thunderstorms likely, mainly from late morning into the afternoon. Some of the storms may produce heavy rain and gusty winds. High 78-85.
Friday night: Partly to mostly cloudy, showers taper off in the evening. Low 65-72.
Saturday: Intervals of clouds and sunshine, a few showers and storms possible in the afternoon. High 80-87.
Saturday night: Mostly cloudy, chance for a few showers. Low 67-74.
Sunday: Mostly cloudy, breezy, showers and thunderstorms likely, some may produce heavy rain. High 76-83.
Sunday night: Plenty of clouds, showers end in the evening. Low 66-73.
Monday: A mix of sun and clouds, chance for a few showers or thunderstorms in the afternoon. High 82-89.
Stop us if you’ve heard this before – we’ll be dealing with upper-level lows and upper-level troughs of low pressure again this week, with more rain on the way.
There is a moderate risk for excessive rainfall across much of the interior today. Image provided by Iowa State University’s Iowa Environmental Mesonet.
A frontal system will move into the region today while a wave of low pressure rides up along it. This system produced extraordinarily heavy rain across western New England and eastern New York yesterday. While we’ll have some of that heavy and thunderstorms moving in today, it shouldn’t be anywhere near the magnitude of what they experienced across the Hudson and Connecticut Valleys yesterday, where as much as 5-10 inches of rain caused widespread severe flooding. Some of the thunderstorms that move through may also produce gusty winds, but heavy rain remains the most significant threat.
The heaviest rain will fall across western and northern New England today and tonight, but some models still show some heavy rain totals around here. Images provided by Pivotal Weather.
That system will pull away on Tuesday with showers ending and some clearing, then high pressure builds in both at the surface and aloft for Wednesday. That means we’ll have sunshine and warm to hot and humid conditions – it’ll feel like summer once again. However, this dry interlude will be short-lived. Another trough of low pressure will start to move into the Midwest by Thursday, and only make very slow eastward progress through the weekend. As disturbances rotate through this upper trough, they’ll generate some showers and thunderstorms around here each afternoon from Thursday into Sunday. None of the days should be a washout, so don’t go cancelling any outdoor plans, but for now Friday and Sunday look to have the greatest coverage of showers and thunderstorms in the afternoon.
One upper-level low moves across the Northeast to start the week, another drops into the Great Lakes later in the week. Loop provided by Tropical Tidbits.
Monday: Plenty of clouds with showers and thunderstorms likely, some heavy rain possible, especially across the interior. High 70-77.
The first half of the weekend looks rather nice, but the second half not so much. Either way, the humidity is going anywhere anytime soon.
Dewpoints will be near or above 70 for the next several days. Loop provided by Pivotal Weather.
Another upper-level low pressure system will settle into the Great Lakes over the next few days, keeping us on the warm and humid side. We’ll stay dry for the most part on Friday and Saturday, aside from a few pop-up showers and thunderstorms each afternoon, mainly across the interior. Temperatures may reach 90 in many areas again on Friday, but as winds become more southerly on Saturday temperatures will be a few degrees cooler, but still well into the 80s in many areas, A frontal system will slowly move toward the region this weekend, and by Sunday it should be close enough to spread more clouds in. A wave of low pressure will develop along the front in the Mid-Atlantic states and ride it northward, bringing us more widespread showers and thunderstorms later Sunday and again on Monday, some of which could be locally heavy, again they’ll be most numerous across the interior.

Thursday night: Clear to partly cloudy with areas fog developing. Low 65-72.
Friday: A mix of sun and clouds, slight chance for an afternoon shower or thunderstorm, mainly well north and west of Boston. High 83-90, a little cooler at the coast.
Friday night: Partly to mostly cloudy with some patchy fog. Low 65-72.
Saturday: Partly sunny, chance for an afternoon shower or thunderstorm, again mostly well north and west of Boston. High 80-87, a little cooler at the coast.
Saturday night: Plenty of clouds, fog possible again. Low 64-71.
Sunday: More clouds than sun with afternoon showers and thunderstorms, especially across the interior. High 77-84.
Sunday night: Mostly cloudy, chance for a few showers. Low 64-71.
Monday: Intervals of clouds and sun with scattered showers and thunderstorms. High 76-83.
Our unsettled pattern will continue for a good chunk of the week, but some changes are expected.

We start the week off with a similar pattern to what we’ve had for a while now. An upper-level trough of low pressure moving from the Great Lakes into the Northeast with a frontal system at the surface stalled out across the region. That front will trigger some showers and thunderstorms again today, a few of which could be quite strong. More heavy rain is possible with some storms, which could lead to areas of flooding, especially from northern Connecticut across central and northeastern Massachusetts and southern New Hampshire, where as much as 2-4 inches of rain fell on Sunday. The front will dissipate across the region on Tuesday, with some additional showers and thunderstorms possible, but they shouldn’t be as widespread as today, which is good news for July 4th celebrations in many locations.
Some additional heavy rainfall is expected across parts of the region today and tomorrow. Images provided by Pivotal Weather.
Wednesday and Thursday feature a change, as a ridge of high pressure builds in both at the surface and aloft. This means we’ll be drier and warmer, with many spots approaching 90 degrees. The change will be short-lived though, as another frontal system approaches on Friday, and slows down as it moves across the region next weekend. A wave of low pressure may ride along it while another upper-level trough moves in from the Midwest, meaning that we’re back in the humid and unsettled pattern. While some showers and thunderstorms are expected each day, none of the days should be a washout.
The combination of heat and humidity will make it feel like it’s in the lower 90s Thursday afternoon. Image provided by WeatherBell.
Monday: Morning fog, then intervals of clouds and sunshine with showers and thunderstorms developing, some may be locally heavy. High 77-84, possibly a little warmer across southeastern Massachusetts and Rhode Island.
Monday night: Partly to mostly cloudy, more showers and thunderstorms through the evening, tapering off overnight, areas of fog develop. Low 63-70.
Independence Day: Partly sunny with a chance for some additional showers and thunderstorms. High 76-83.
Tuesday night: Showers and storms end in the evening, then becoming partly cloudy. Low 62-69.
Wednesday: Partly to mostly sunny. High 81-88.
Thursday: Sunshine and a few clouds. High 83-90, a little cooler right at the coast.
Friday: A mix of sun and clouds, chance for a few late-day showers and thunderstorms. High 82-89.
Saturday: Partly sunny with some showers and thunderstorms possible. High 79-86.
Sunday: Intervals of clouds and sun with more showers and thunderstorms likely. High 77-84.
While the weather won’t be perfect for a long holiday weekend, it won’t be as bad as your weather app say it will be.
Believe it or not, rainfall has actually been below normal this morning for a good portion of the region. Images provided by the Northeast Regional Climate Center.
We’ll have high pressure building in, and remaining in place through Saturday, which means drier weather and lower humidity, but it will remain warm. There’s still a slight chance for a pop-up shower Friday afternoon, but these should be few and far between. Clouds will start to move in late Saturday ahead of a slow-moving frontal system. In addition, another upper-level low will move into the Great Lakes, with disturbances riding around it. So, that means that for Sunday, Monday, and July 4th, we’re back in the same pattern we’ve been in, with higher humidity, and a daily chance for showers and thunderstorms, mainly during the afternoon and evening hours. None of the days should be a washout, but if you’ve got outdoor plans, make sure you keep an eye on the sky (or the radar), and be prepared to head inside if need be. For fireworks displays Tuesday night, most of the thunderstorm activity should diminish after sunset, but obviously, this is a little hard to pinpoint several days in advance.
Longer-range forecasts show no end to this pattern, with troughs of low pressure and/or cutoff lows continuing to drop into the Great Lakes and the Northeast. Loop provided by Tropical Tidbits.
Thursday night: Clear to partly cloudy, some patchy fog may develop. Low 60-67.

This week’s forecast is fairly simple, because we’re stuck in the same weather pattern that we’ve been in for quite some time.
One upper-level low slowly moves through this week, another one starts to move in next weekend. Loop provided by Tropical Tidbits.
Upper-level low pressure over the Great Lakes will very slowly move eastward this week while weakening. As disturbances rotate around this low, we’ll have a daily chance for showers and thunderstorms, mainly during the afternoon and evening each day. Not everyone will get these, and none of the days will be a washout, but the threat exists each day for some showers and thunderstorms. Any storms that do form will likely produce heavy downpours, as we’ll have a warm and humid airmass in place. A few strong to severe storms are possible, especially today, but for the most part, we’re just looking at your typical garden-variety thunderstorms each day. The upper low finally starts to move out next weekend, but another one drops right into the Great Lakes in its place, keeping the unsettled weather going for a few more days.
With all the cloudcover, temperatures will average a little below normal for most of the next week. Image provided by Weathermodels.com
Monday: Morning fog, then intervals of clouds and sun with showers and thunderstorms developing, some could be quite strong. High 77-84, a little cooler along the coast from the North Shore to the New Hampshire Seacoast.
Monday night: Mostly cloudy, fog redevelops, a few more showers, mainly during the evening. Low 62-69.
Tuesday: Partly to mostly cloudy, breezy with some afternoon showers and thunderstorms. High 72-79.
Tuesday night: Mostly cloudy, showers taper off in the evening, fog likely again. Low 62-69.
Wednesday: Intervals of clouds and sun, breezy, chance for a few afternoon showers and thunderstorms. High 73-80.
Thursday: Partly sunny, some showers and thunderstorms likely in the afternoon. High 74-81.
Friday: Partly sunny, an isolated shower or thunderstorm possible. High 73-80.
Saturday: Intervals of clouds and sun, breezy, chance for an afternoon shower or thunderstorm. High 76-83.
Sunday: More clouds than sun, breezy, more showers and thunderstorms possible. High 74-81.
The first weekend of summer is not going to feature much, if any sunshine, but it will be warm and humid. Meanwhile, the tropics are in mid-summer mode.
Dewpoints will be near or just above 70 across the region Saturday afternoon. Image provided by WeatherBell.
As has been the case for the past couple of months, an upper-level low will be the main driver of our weather for the next few days as it lifts northward from the Tennessee Valley into the eastern Great Lakes and then across the Northeast. Low pressure at the surface will send a warm front our way, spreading lots of clouds in tonight, with a noticeable increase in humidity on Friday as the front moves through. The front may be accompanied by a few showers and thunderstorms, but it won’t be a washout. Showers and thunderstorms may be a little more numerous on Saturday, and some of them could be locally heavy. More showers and thunderstorms are possible on Sunday as the system moves across the region and off to the east. So, things improve on Monday, right? Try again. Another upper-level low moves into the Midwest, which means unsettled conditions continue, with some additional showers and thunderstorms, and this pattern may persist for a good chunk of next week. Keep in mind, that even though there are showers and thunderstorms in the forecast every day, each day shouldn’t be a washout. They’ll be most likely during the afternoon and evening each day, but it doesn’t mean they’ll cover the entire area.
Despite the showers and storms forecast each day this weekend, most of the models are not showing an excessive amount of rainfall. Images provided by Pivotal Weather.
Meanwhile, in the tropics, things have gotten active. Thanks to sea surface temperatures more reminiscent of late August than late June, two tropical systems have developed from waves moving off the African coast. We usually don’t see storms of this type begin to develop until late July or August, and to have two of them in June is extremely rare. The more immediate concern is Tropical Storm Bret. As of 2pm Thursday, Bret was centered about 45 miles east-northeast of Barbados, moving toward the west at 14 mph. Maximum sustained winds were near 65 mph. Barbados has already reported wind gusts as high as 52 mph. Tropical Storm Watches and Warnings are in effect for many of the islands in the Lesser Antilles. Bret has likely peaked in intensity, but it will bring very squally conditions to the islands as it moves through later today and tonight. Once it moves into the eastern Caribbean on Friday, increasing wind shear will begin to rip the system apart, and it should weaken and degenerate into a tropical wave over the weekend as it moves into the central Caribbean.
As Bret approaches the Lesser Antilles, the wind shear is evident as most of the thunderstorm activity is displaced east of the center. Loop provided by NOAA.
Meanwhile, Tropical Depression Four has developed in the Central Atlantic. As of 11am Thursday, it was centered about 1270 miles east of the Lesser Antilles, moving toward the west-northwest at 15 mph. Maximum sustained winds were near 35 mph. This system should strengthen into Tropical Storm Cindy over the next day or so, and will continue to strengthen through Saturday. However, after that, increasing wind shear will begin to take its toll on this system as well, and it will begin to weak. The track should bring in more toward the northwest with time, meaning it will stay over the open waters of the Central Atlantic, and not impact any land areas.
None of the models show TD 4 as a threat to any land areas over the next 3-5 days. Image provided by Tropical Tidbits.
Thursday night: Becoming mostly cloudy with areas of fog likely, a shower or two is possible. Low 54-61.
Friday: Partly to mostly cloudy, much more humid, chance for a few showers, mainly across the interior. High 74-81.
Friday night: Mostly cloudy, a shower is possible, mainly during the evening. Low 62-69.
Saturday: Partly to mostly cloudy, showers and thunderstorms expected in the afternoon. High 75-82.
Saturday night: Plenty of clouds, a few showers around. Low 62-69.
Sunday: Clouds with some sunny breaks, more showers and thunderstorms possible. High 78-85.
Sunday night: Partly to mostly cloudy, some additional showers likely, especially during the evening. Low 61-68.
Monday: Partly to mostly cloudy with more showers and thunderstorms likely. High 77-84.
Astronomical summer begins at 10:57am Wednesday, and right on cue, some summer weather will move into the region by then.

The week starts off with yet another upper-level low in place across the Northeast, which means we’ll have plenty of clouds generated each day along with some showers during the afternoon and evening hours. Showers may continue for a good chunk of the night tonight as another disturbance rotates around that upper-level low. Temperatures will remain on the cool side for mid-June, especially near the coast, where a seabreeze is likely. By Wednesday, the upper-level low moves away, and a ridge of high pressure builds into the East Coast. As a result, we’ll turn drier and warmer, with temperatures likely getting into the 80s in many locations, possibly approaching 90, especially on Friday. With the warmth will come increasing humidity levels, especially over the weekend, and which may allow for a few thunderstorms to pop Friday afternoon. The ridge starts to break down over the weekend as a disturbance moves toward the region, likely producing some showers and thunderstorms. Showers and thunderstorms become a little more numerous on Sunday ahead of a cold front dropping down from the north.
Dewpoints could climb into the lower 70s around here by next Saturday. Images provided by Weathermodels.com
On a separate note, the tropics are starting to show signs of life. Aided by sea surface temperatures more reminiscent of late August than mid-June, a tropical wave that moved off the coast of Africa a few days ago has been slowly organizing over the weekend, Conditions are favorable for further development, and it will likely become a tropical depression at some point later today or Tuesday. Its immediate future calls for a westward track with gradual strengthening, and no threat to land for much of the upcoming week. As we get to the end of the week, that becomes more complicated. Once the storm does form, we’ll have a more detailed blog post about it, and what its future may look like.

Saturday: More clouds than sun, breezy, scattered showers and thunderstorms develop. High 80-87.
Sunday: Partly to mostly cloudy, breezy, more showers and thunderstorms expected. High 75-82.
We’ve got good news and bad news. Good news: the 4-day period this forecast encompasses won’t be half bad. Bad news: the 4-day period this forecast encompasses will be half bad.
Friday is the pick of the weekend with temperatures topping 80 in much of the region. Image provided by WeatherBell.
We start off with high pressure in control tonight and early Friday with dry and seasonably mild conditions. Low pressure sends a warm front our way on Friday, with more clouds in the afternoon along with more humid air, and eventually, some showers and thunderstorms by evening. The low pressure system will take it’s time moving across the region as it will be accompanied by yet another upper-level low, which means Saturday will feature occasional showers and thunderstorms and cooler temperatures. The showers will likely continue into early Sunday before tapering off, but with the low only slowly departing, clouds will remain for much of the day. We should see some improvement on Monday, but with that upper-level low nearby, we could see a few pop-up showers in the afternoon.
Many of the models are showing quite a bit of rain around here this weekend. Images provided by Pivotal Weather.
Thursday night: Clear skies. Low 56-63.
Friday: Sunshine in the morning then clouds start to increase along with humidity levels, showers and thunderstorms possible by evening. High 77-84.
Friday night: Scattered showers and thunderstorms. Low 56-63.
Saturday: Cloudy with occasional showers and some bouts of steadier rain, a few thunderstorms possible as well. High 62-69.
Saturday night: Plenty of clouds with a few more showers likely. Low 52-59.
Sunday: Showers taper off in the morning, mostly cloudy in the afternoon with a few breaks of sun possible. High 63-70.
Sunday night: Partly to mostly cloudy. Low 51-58.
Monday: Partly sunny, a shower is possible during the afternoon. High 66-73.
