New England has one more summery day left before a rather strong cold front brings us back to October. This will also bring a slug of much-needed rain.

Most of New England has one more day of well above average temperatures today. Far western and northern areas will be a notch cooler as clouds and some showers will arrive ahead of a rather strong cold front approaching the region. Widespread 80s are once again possible this afternoon. Yesterday's h...

The widespread high temperatures in the 80s weren't quite enough to break daily records in southern New England, but the widespread 80s in northern New England certainly were. Caribou's high of 83° beat their previous record by 9°.

This week will start off where the weekend left off. A cold front mid-week will bring a nice slug of rain before cooling things back off to our October reality. There will be a potential coastal storm to watch for the upcoming weekend as well.

The peak of this sustained October warmth will likely come Sunday through Tuesday for New England. A subtle shift in flow will likely occur on Sunday, which will keep eastern areas of the region a notch cooler as winds come off the ocean. The northern tier of the region will likely be the warmest (relative to averages), with temperatures sinking slightly moving closer and closer to the coast. Widespread 80s will still be likely across much of the region, but daily records will likely only be in jeopardy across the north on Sunday.

All of New England, right to the coast, will see peak warmth Monday and Tuesday. As the high pressure begins to shift to the east, the pressure gradient will increase, allowing a stronger southwesterly flow. This flow will prevent sea breezes from developing and 80+° temperatures will likely push to the coast. Each day will be similar to each other with highs likely only a degree or two different. Clouds will likely begin to increase slightly from the full sunshine expected over the weekend.

Daily record highs will be possible across the region during this stretch. Daily records are highly variable across the region during this stretch, ranging from the upper 70s to low 90s depending on the location in New England. October 7th (Tuesday), for example, has a record high of 91° in Hartford and 90° in Boston and Manchester. Caribou and Houlton, Maine's daily record on that same day is just 76°. On Monday, Caribou and Houlton's records in the low 70s are expected to be topped by several degrees.

The ridge of high pressure will shift farther east Tuesday, with a cold front crashing through the region Tuesday night into Wednesday. This will bring temperatures crashing back down to our October reality. It should also bring a decent slug of widespread rainfall. It looks like the rainfall will move west to east Wednesday morning for most, but several days out, timing can always change. A widespread half inch to inch of rain is currently favored, but this could certainly trend in a drier direction. Either way, it will be a welcome rain, but may do little in terms of drought-denting.

Sustained warmth for New England begins today. It will persist through Tuesday with widespread highs in the upper 70s to mid possible. We crash back to reality next Wednesday.

A multi-day stretch of well above average temperatures has arrived for New England. Widespread mid-70s north to low 80s south will persist for the region into early next week. This will come as a rather strong area of high pressure has slipped to New England's south, resulting in a southerly return....

It's now the quintessential autumn month in New England. This one may have some trouble producing sustained chill, however. Read our monthly outlook here:

It's officially the month of Halloween, pumpkins, fairs and fall foliage. Average high temperatures drop about 12 to 15 degrees from October 1st to October 31st. The region will also lose nearly an hour of daylight from the start to the end of the month as well.Summary: This October will likely feat...

Another chilly night is in store for tonight under high pressure. Now that it's October, frost and freeze alerts will no longer be posted for northernmost New Hampshire, Maine and the Northeast Kingdom. Surf remains rough from Humberto as well.

01/10/2025

Cool days and crisp nights are how October will start off for New England, but it won't last very long as a sharp warm-up arrives this weekend.

A large area of Canadian high pressure has built into New England behind a cold frontal passage. This will bring a much cooler air mass to the region for Wednesday and Thursday. Widespread highs in the 50s north and 60s south are likely both days. A rather strong pressure gradient between the high p...

A quick burst of fall begins tonight. A couple cool days and crisp nights will be followed by a sharp warm-up, which will likely sustain into early next week. Frosts and freezes will be coming and likely expanding south for the next couple nights.

30/09/2025

A large area of Canadian high pressure will build into the region behind Tuesday's cold front. This will bring a much cooler air mass to the region for Wednesday and Thursday. Widespread highs in the 50s north and 60s south are likely both days. A rather strong pressure gradient between the high pressure centered just north of New England and the passing Hurricane Humberto well offshore will allow for breezy conditions. Northeast gusts of 20-30mph will be possible, adding to the October chill in the air.

With strong high pressure sinking southward, Wednesday night and Thursday will feature strong radiational cooling conditions. Clear skies, no humidity to speak of, and weakening winds should allow temperatures to bottom out both nights. Widespread low in the 30s are possible across the region with 20s across the northern tier and higher elevations. Southern New England will likely pick up their first frost advisories of the season this week.

Tropical Storm Imelda will be diverted away from New England by this sprawling high pressure system. This will set up a blocking pattern reminiscent of a Rex Block (named after the meteorologist who discovered it). This block involves an area of high pressure located directly north of an area of low pressure. This will slow down Imelda's movement through mid-week before the storm is shoved around the high pressure system, well away from New England.

This big, bold high pressure system will remain centered to New England's southwest through the weekend. This will set up a southwest flow and warm air advection once again. Widespread highs well into the 70s will likely return. There are decently strong signals already for temperatures to reach 80° across lower elevations of southern and central New England. Outside of these warm temperatures, the sprawling high will lead to bright, sunny skies and continued bone-dry weather.

After some active weather last week, New England will revert right back to quiet and bone-dry weather for this week. Temperatures will also be swinging back and forth.

The main weather stories for the east coast next week will be dueling tropical systems in the Atlantic. The more powerful storm will be Hurricane Humberto. The hurricane is currently a category four storm northeast of Puerto Rico. This storm will remain well offshore of the United States and Caribbean Islands, though it may come close to Bermuda. The second storm is currently Tropical Depression Nine. As of writing this storm is on the verge of becoming Tropical Storm Imelda.

Both storms will likely be diverted away from New England as a sprawling high pressure system looks to set up over the northeast. This will likely set up a blocking pattern. This specific type of block is commonly known as a Rex Block (named after the meteorologist who discovered it). This block involves an area of high pressure located directly north of an area of low pressure. This setup blocks the low pressure from traveling north and west along the jet stream, which is what all storms want to do.

This pattern can often lead to a flip-flop in the weather with cooler and unsettled conditions to the south and warmer and drier weather to the north. In this case, Imelda will act as the low pressure, bringing multiple rounds of rain to the south while New England stays warmer (at least initially next week) and mostly dry. A cold front will drop through New England around Tuesday to Tuesday night of next week, bringing a cool-down, so New England may not be particularly "warmer" than the south by the middle of next week.

As always in this setup (and all blocking patterns, really), there's low confidence in exactly where the low pressure system will set up and the northern extent of its precipitation. At this point, it is expected to remain well south of New England, but trends toward a more northerly solution of both the high and low pressure systems could see the precipitation tick northward, so trends will be watched, but a dry outcome is heavily favored right now. High pressure is expected to stick around through the week, keeping precipitation chances very low for the foreseeable future.
