Area Forecast Discussion National Weather Service Gray ME 737 PM EST Tue Feb 18 2025

SYNOPSIS
Cold high pressure builds in early this week with gusty winds diminishing this evening and tonight. Low pressure likely passes well south of New England on Thursday. High pressure then continues to gradually build in during the weekend with a moderating trend.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
Updated temperatures, winds and surface dew points for the near term portion of the forecast. Dry conditions will continue outside of a few upslope snow showers in the mountains Temperatures will be falling below zero in the north this evening.

Prev Disc...
Breezy but otherwise quiet weather continues into early this evening. Forecast soundings support gusts of 30 to 40 mph for a few more hours, but then winds will then steadily ease through tonight (although still 20-25 mph at times). Latest RAP analysis indicates a 500mb shortwave draped across the International Border, and this will gradually work its way southward through this evening into the early part of tonight.
It will be running into quite a bit of dry air, so for areas south of the mountains, mainly just an increase in cloud cover with perhaps some flurries here and there. In the mountains, there will be a continued chance of snow showers tonight with upslope flow remaining.

It will be another cold night with enough of a breezy to bring wind chills as low as -10F south of the mountains and -15F to -20F in the mountains (except much lower going up in elevation).

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/
Model guidance is depicting a weak upper low forming across southern Quebec on Wednesday, resulting in a few snow showers for far northern areas (with upslope flow still in place too).
Otherwise dry conditions are expected across the remainder of the area as low pressure currently over the Canadian Maritimes pulls farther away. This will allow the pressure gradient to relax and result in less breezy conditions across the area, but we still may see gusts 25-30 mph in the morning before a downward trend going into the afternoon. Comparatively, it will probably feel pretty nice out compared to today and Monday with the lighter winds and temperatures mostly in the 20s, except some teens in the mountains.

Low pressure emerges off the coast of the Carolinas Wednesday night while shortwave ridging overhead maintains dry conditions over New England. Winds will be light enough for good radiational cooling, but there may be some mid/high clouds from the low pressure well to the south that end up leveling off cooling at some point overnight.
I have blended in some cooler guidance to bring temps down a bit but haven't gone too low due to the potential increasing clouds.

LONG TERM /THURSDAY THROUGH TUESDAY/
Key Messages:

* Coastal low brushes the area to the south and east Thursday evening with some potential flurries/snow showers along the coast.
Gusty northwest winds are expected in the wake of this system Friday.

* Quiet period of weather beyond this through early next week with temperatures moving to around...or just above normal.

--Pattern and Summary--

There is a pattern shift occurring over the northern hemisphere this week as downstream blocking over Greenland relents and the NAO pushes into positive territory by week's end
In the Pacific
a similar...though less dramatic shift in the EPO from negative to positive will allow for an increasing Pacific influence across North America. Ensembles are in good agreement on an extended stretch of quiet weather through the long the forecast period with the increasing Pacific influence bringing slowly moderating temperatures.

--Details--

Thursday: EC-EPS/GEFS in strong agreement that trough digging into the northeastern US will spawn low pressure which will remain well south and east of the benchmark late Thursday and Thursday night.
Despite this track...some of the guidance suite has some light snow brushing coastal areas
Otherwise
mostly cloudy and seasonably cool conditions with northerly winds strengthening Thursday night.

Friday through Sunday: High pressure ridge axis builds into the region for Friday and Saturday before a northwesterly flow regime becomes entrenched aloft. Well-placed DGZ and NNW upslope supports mountain SHSN Thursday night into Friday with otherwise dry conditions with quiet weather to the south and east. T9s around -10C Friday and Saturday begin to moderate to around -7C Sunday as the flow begins to back ahead of next approaching northern stream wave.
This will yield highs in the 20s on Friday moderating to the upper 20s-mid 30s from north to south by Sunday.

Monday and Tuesday: Fast-moving, shortwave-laden northwesterly flow opens the new work week with mountain snow showers...some of which may push into the foothills and coastal plain. Temperatures should end the period close to seasonal norms...with most spots in the 30s.

AVIATION /01Z WEDNESDAY THROUGH SUNDAY/
Short Term...Mainly VFR through Wednesday night, except for the possibility of MVFR ceilings/snow showers at HIE. Even though west to northwest winds will remain somewhat breezy into this evening, a steady downward trend is expected through tonight.
Winds will be less breezy Wednesday but could reach 20-25 kt at times, mostly in the morning.

Long Term...VFR conditions are expected to dominate the long term forecast period. Low pressure passing well south and east of the region Thursday night may spread a few flurries/light SHSN to the coastal terminals. Gusty northwest winds /15G25kts/ are expected Friday before quieter conditions through the weekend.

MARINE
Short Term...Gales persist through this evening but will switch to SCA conditions overnight through early Wednesday morning as winds gradually subside. Conditions then likely remain below SCA levels through Wednesday night.

Long Term...Low pressure will pass south and east of the waters Thursday night with gusty northwest winds developing as it departs Friday. SCAs will be necessary and depending on the proximity of the low...gale force wind gusts will be possible over the outer waters. Northwest winds will subside as a high pressure ridge axis builds into the region this weekend.

GYX WATCHES/WARNINGS/ADVISORIES
