Area Forecast Discussion National Weather Service Gray ME 313 AM EST Wed Feb 19 2025
SYNOPSIS
The northwest gradient over New England weakens today allowing for breezy winds to subside. Low pressure will pass well south of the area Thursday. High pressure over the Plains slides east through the end of the week with the center of the high settling south of New England. This will allow for mostly dry conditions to continue with a warming trend.
NEAR TERM /THROUGH TODAY/
Breezy northwest winds will bring windchills below zero this morning. Northwest winds will be on the downward trend late this morning into the afternoon as the gradient over the area slackens. Today will be mostly dry with mostly sunny skies down stream of the mountains. Highs today will range from the teens across the north and 20s across the south.
SHORT TERM /TONIGHT THROUGH 6 PM THURSDAY/
A positively tilted trough over the eastern CONUS will spawn a low pressure system off the Southeast Coast tonight. The 00Z model suite is in good agreement that this system will pass too far offshore to bring precipitation to the area tonight through Thursday. Therefore mostly dry conditions will continue with lows tonight ranging from the single digits below zero to single digits above zero.
The aforementioned trough will become a closed upper low Thursday that tracks near southern New England. This upper low will lead to more in the way of clouds Thursday with highs mainly in the 20s.
LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/
04Z Long Term Forecast Update... Little change in the latest NBM guidance for the extended portion of the forecast. Low pressure passing well southeast of the area may result in a few flurries over the southern coast on Thursday. After this mainly dry weather and moderating temperatures look likely with our next chance for precipitation possibly arriving early next week.
Previously...
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 /08Z WEDNESDAY THROUGH SUNDAY/
Short Term...Mainly VFR will prevail today through Thursday with NW winds subsiding this afternoon.
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...NW winds and elevated seas will warrant an SCA into mid morning with winds and seas subsiding this afternoon.
Cold air advection over the waters this morning will bring the threat for moderate freezing spray. Winds and seas remain below SCA thresholds tonight through Thursday.
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
ME...None.
NH...None.
MARINE...Small Craft Advisory until 10 AM EST this morning for ANZ150>152-154.
