Synopsis for stonington me to merrimack river ma out to 25 nm high pressure continues to move offshore south of the waters today, bringing a freshening southwesterly flow. A weak area of low pressure along a cold front crosses the waters Friday night, with a cold front stalling across the waters behind the system this weekend. High pressure mostly passes to the north this weekend. Multiple weak disturbances move along the front this weekend, with a potentially stronger coastal low possible early next week.

Area Forecast Discussion National Weather Service Gray ME 1007 AM EST Thu Nov 30 2023
SYNOPSIS
A brief little warm up is expected to close out the work week, with temperatures by Friday making a run into the 50s for southern New Hampshire and coastal western Maine. By Friday an area of mostly rain will slide across New England, but some light snow is possible in the mountains. Even though the main area of precipitation moves out rather quickly Saturday morning, some showery weather is likely to continue through the weekend.
Attention then turns to early next week, when a more organized coastal storm is possible.
NEAR TERM /UNTIL 6 PM THIS EVENING/
10:05am Update...Just made minor changes to align with current observations, the biggest being holding on to clouds up north a bit longer. Otherwise, the going forecast is in good shape as drier air is moving in and area webcams show snow showers have ended across the far north.
7:05am Update... Increased cloud cover and had to introduce some isolated snow showers across the Whites as a weak mid level disturbance and passing warm front generate a few flakes this morning. The clouds look to decrease in coverage through the morning, with more sun for the afternoon. Otherwise, no notable changes with this update.
Previous...
Southwesterly flow helps usher in some warmer air today as high pressure moves offshore south of New England today. Temps warm into the mid 30s across the north, and into the mid 40s along the coastline, running about ten degrees warmer than yesterday.
A weak upper level disturbance brings some high level clouds today, with increasing sunshine expected for the afternoon.
Otherwise, a fairly quiet and seasonable day is expected.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/
Temps remain warmer tonight as the southerly flow continues to bring in mild and more moist air. Winds are likely to drop off during the overnight through the valley's. Another weak upper level disturbance races through during the overnight hours, resulting in mainly cloudy skies through the late evening and most of the overnight hours. This should help to keep temperatures higher, but holes in the clouds will allow for localized cooling, especially across the north where snow cover is common. Clouds clear late tonight before returning with the next disturbance tomorrow.
A weak area of low pressure quickly approaches the area during the day tomorrow. Morning sunshine allows temps to warm to near 50 across southern areas, before increasing afternoon clouds puts a lid on the highs.
The system approaching tomorrow will be moving very quickly, moving from New Mexico to New York in about a 24 hour period.
This result in a quick change in conditions from sunshine to light rain in only a few hours during the afternoon. The first raindrops likely arrive around sunset across western New Hampshire, and then overspread the rest of the area during the early evening hours. Most areas see light rain, while only some of the higher terrain across the north see a change to snow during the early evening. The rain looks to be widespread but light in amounts across the area, owing to both the speed of the system and light nature of the rain.
LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/
Overview: Western CONUS trof gradually shifts eastward over the weekend and becomes more established in the OH River Valley by early next week. While it may be near normal for the weekend...overall the pattern is conducive for continued cooler than normal weather. The pattern will also be an active one...with higher than normal chances for precip.
Impacts: While precip Fri night looks to be mild enough for mostly rain...some light accumulations are possible in the mtns.
However the next storm system has the potential to be a little snowier early next week.
Forecast Details: As the western CONUS trof digs and shifts east into the central Plains...WAA will have developed over the Northeast by Fri and Fri night. As a result a period of overrunning precip is expected locally. However mild antecedent conditions will favor mostly rain. Marginal cold lurking near the Canadian border may lead to some light accumulations...but even the northernmost zones will have a tough time accumulating much unless snowfall rates increase more than forecast.
Model guidance is forecasting quite a few individual S/WV trofs embedded within the larger trof...and so keep showery weather going thru much of the weekend. The majority of those showers will be confined to the mtns...but a well timed S/WV trof coinciding with peak heating could result in more widespread showers.
More interesting will be early next week as the main trof axis shifts from the eastern Great Lakes to offshore. As it does so the pattern is set up well for a coastal storm to at least be in the vicinity. There will be sufficient cold air in place that if the low pressure does take a track into the Gulf of ME that snow is a distinct possibility. Examining the ensemble guidance on DESI shows a mean snowfall higher than the 50th percentile...suggesting that a few very snowy members are dragging the mean upwards. This is confirmed by the ECMWF EFI remaining low for the area...but the shift of tails popping up locally. All this is to say that the highest members have notable snowfall...but many have minor to no accumulation.
There are three major camps of ensemble members at this time.
One featuring a deeper trof as it crosses the Eastern Seaboard, another than remains flatter, and lastly a delayed trof. Just under a third of the members fall into that second...least snowy cluster. However the low 50th percentile snowfall of the other two clusters suggests that timing and strength difference in the low forecast is still controlling how long and how much it may be able to snow. Given that S/WV trofing contributing to this forecast storm is still over the northeast Pacific...south of AK...much can change over the next 24 to 48 hours.
AVIATION /15Z THURSDAY THROUGH MONDAY/
Short Term...Other than a brief period of MVFR ceilings at HIE this morning, VFR conditions prevail through midday tomorrow, and then a period of MVFR to IFR ceilings is likely with light rain late tomorrow afternoon and early evening. West- southwesterly wind shear up to 40kts is likely later tonight.
Long Term...An area of mainly rain sliding across northern New England will continue a period of IFR conditions early Sat. By afternoon downsloping will return areas south of the mtns to VFR...while lingering MVFR CIGs will be possible to the north.
Showery weather may continue thru the weekend...but overall it is anticipated that VFR conditions predominate. As early as Mon a more significant coastal storm is possible. Depending on track widespread IFR conditions are possible...at least in part due to snowfall.
MARINE
Short Term...SCA conditions return this afternoon with freshening southwesterly winds as high pressure remains south of the waters. A few gusts to gale force are possible across far eastern waters for a brief period of time late tonight. Winds then ease tomorrow morning as a weak area of low pressure approaches the waters.
Long Term...Winds and seas are generally forecast to remain below SCA thresholds thru the weekend. A coastal storm will bring northeast winds to the waters early next week. While the exact track and strength still carries a lot of uncertainty...a period of SCA conditions would be likely.
