By this weekend, the trough we've been under will begin to shift eastward while high pressure builds in from the west. Overall, broad troughing is expected to persist over the region while surface high pressure keeps the region dry (something that was in question earlier in the week). This will allow for continued partial sunniness, but also continually dropping temperatures, with widespread highs in the mid 40s north to mid 50s south by Sunday.

Our stretch of rather mild mid-fall temperatures has ended for most (eastern Maine will remain generally milder for a couple more days). Each day will likely be a notch cooler than the last through early next week. This will come as an area of Canadian high pressure continues to build into New England, resulting in a brisk northwest flow. It certainly won't be notably cold given we're quickly approaching November; generally seasonable temperatures are expected over the next week or so.

Looking toward the middle and end of next week, a large-scale blocking pattern reminiscent of a Rex Block may set up (this block involves an area of high pressure directly north of an area of low pressure). A large, strong and expansive ridge to the north of New England is likely to form. This will force New England into continued troughing while the ridging remains across Canada.

This large-scale setup will promote a slow-moving area of low pressure to impact New England around the middle to end of next week. A piece of northern-stream energy will likely drop southward into the Midwest due to the aforementioned ridging. This northern-stream system is looking increasingly likely to spawn a secondary low off the east coast by next Wednesday or Thursday, which would likely move offshore of New England right around Halloween, bringing a period of rain and possibly wind.

New England will remain settled under broad troughing for the remainder of October. This will bring mid-fall chill and periods of unsettled weather. The next organized system looks to arrive just before Halloween.

The upper-level low responsible for the frontal passage across New England will remain north of New England through the end of this week. This will promote broad cyclonic flow across the northeast. Broad cyclonic flow is synonymous with partly to mostly cloudy skies building in the afternoon, cool t...

Today will mark the beginning of a sustained cool-down for New England. Each day will be a notch cooler than the last through early next week. After today's frontal passage, New England will get a break from organized weather makers.

Another frontal system will continue to cross New England from west to east through the day today. This system is progressive and will move rather quickly across New England this afternoon and evening. Widespread rain across much of the region this morning will have pushed into Maine for the afterno...

Tonight through tomorrow will be a near-repeat of Monday's setup. The biggest difference is that this system will be weaker with more muted effects. This means a bit less rain and a shorter duration.

A narrow short-wave ridge will build into most of New England on Tuesday. This ridge will build between the departing low pressure system and another quickly approaching from the Great Lakes. This will give New England a one-day break from the active weather (for the most part). Skies will see variable clouds, with more generally building later in the day as the next system approaches. That system may send its first showers into westernmost New England by the evening.

For Wednesday, a very similar setup to Monday looks to play out. This will come as another rather strong frontal system moves just to New England's north, dragging a cold/occluded front across the region. Similar to Monday, a secondary low is currently not expected to form, which will keep this system from becoming a longer duration storm. At this point, even the timing looks similar, with a line of showers moving from west to east from Tuesday night through Wednesday afternoon.

This system doesn't look quite as potent as today's system. Rainfall rates look to be lower and the wind currently doesn't look nearly as strong. At this point, a widespread quarter to half inch of rain across the region looks likely. In a flip from Monday, the highest rainfall totals will likely set up across interior Maine, with totals dropping gradually moving south and west in the region.

A ridge-in-the-west-trough-in-the-east pattern looks to set up for late this week. This will keep New England under broad cyclonic flow and troughing. Thursday and Friday. This will allow for cooler than average weather for late-October along with partly to mostly cloudy skies. There won't be any organized systems during this time, but a few subtle waves will likely pass, allowing for the potential for some spot showers. Much of this time will be dry and precipitation will be most likely within the mountains.

It'll be a generally active week with troughing dominating. Frontal systems will cross the region today and Wednesday, making those days the wettest ones. Troughing will help keep things cooler later in the week as well.

A potent frontal system will bring a punch of rain and wind tomorrow morning. A lack of a secondary low will keep this a rather quick punch, but a few hours of downpours and locally high wind gusts are likely from west to east.

While total rainfall is a pivotal part of droughts, there are other atmospheric conditions that have been present across the region that have led to northern New England's extreme drought status.

Throughout much of last winter, New England began to creep toward drought conditions as much of the season saw long stretches of cold and dry weather. By the start of 2025, much of New England was in moderate or severe drought conditions. A rather wet spring came along (with a wetter end to winter a...

There's been some very nice weekends in New England weather-wise this fall. That will continue this weekend with a bit of a warming trend through Sunday. Some more beneficial rain arrives once again late Sunday and Monday.

16/10/2025

A chilly breeze will persist over New England for another 18 hours or so. After that, a warm-up is in store for the weekend. The next bout of unsettled weather will arrive late this weekend.

Today, an upper-level low will drop down from the Nova Scotia area into New England's coastal waters, likely around eastern Maine. This system may retrograde westward a bit, putting New England within a trough. The pressure gradient will remain rather tight on Thursday, keeping conditions on the bre...

The storm system has officially left New England, but breezy conditions will persist for the rest of the week. A warming trend will also be in store after a quick cool down tomorrow.

The nor'easter that arrived on Sunday has finally pulled out to sea after getting hung up by high pressure. Final rain totals from the storm show over a half a foot fell across southeast Massachusetts. Unfortunately, not all of New England got in on the storm, and the areas entrenched in an extreme....

Final rain totals show over a half a foot fell across southeast Massachusetts. Unfortunately, not all of New England got in on the storm, and the areas entrenched in an extreme drought across northern New England didn't very see much as high pressure kept the rain to the south.
