Area Forecast Discussion National Weather Service Gray ME 618 PM EDT Sun Apr 20 2025

SYNOPSIS
High pressure moves in from the west tonight, which will allow winds to diminish this evening. The high crosses the region on Monday for a fair and seasonable day. It will not stick around long though, and rain showers will move in Monday night into Tuesday morning. Showers will be light and some places may not see much if any rainfall. It will then stay dry and seasonable through the end of the work week.

NEAR TERM /THROUGH MONDAY/
615 PM Update... Allowed the Red Flag Warning and Wind Advisory to expire as winds will continue to gradually diminish through this evening and relative humidity will also begin to increase.
Otherwise, just loaded in the latest surface observations at this time.

Previously...
As sfc low over the maritimes moves E into tonight, and sfc high to our W weakens as it moves toward New England, those strong and gusty NW winds will diminish toward sunset, and will actually become light by around midnight, as that sfc ridge moves into the CWA from the W. Will actually see some decoupling occur for the second half of the night which will allow some of the colder spots in the N to drop into the mid 20s, and those areas that decouple in the S could see some upper 20s. Otherwise mins range from the upper 20s in the mtns to the low to mid 30s in the S.

SHORT TERM /MONDAY NIGHT/
The sfc high crosses the CWA during the morning and then shifts SE in the afternoon. Much of the day will be mostly sunny, but some cirrus and mid level clouds move into the Ct valley mid to late afternoon and could spread into W ME before sunset. Given the lack of much gradient flow until late in the day, sea breeze should develop along the coast early to mid afternoon, and temps will max out there around midday to early afternoon. So, highs range from the mid to upper 50s along the coast and in the mtns to the low to mid 60s in the S half of NH.

Weakening low pressure moves ENE out of the Great Lakes Mon night, and this will bring in some light and showery WAA Mon night. Rain showers move into W areas in the evening but will overspread the entire area after midnight. SW flow will pick up a bit in the second part of the night, and mins will likely be hot around midnight, and range from around 40 in the mtns to the low to mid 40s in the S, with temps mostly steady during the pre-dawn hours.

LONG TERM /TUESDAY THROUGH SUNDAY/
Key Message: Pretty typical spring weather with no significant precip events thru the extended.

Impacts: No significant weather impacts anticipated.

Forecast Details: Precip looks to more or less come to an end around midday Tue. Showers may linger in the mtns into the afternoon as winds turn northwesterly and upslope over the terrain.

Remainder of the week looks dry and seasonable. There is no strong signal on ensemble guidance for much above or below normal temps. It looks a little milder than normal away from the coast...and near normal near the coast where sea breezes will undercut the warm afternoons.

The next precip chance will come over the weekend...again. But there is pretty large spread in start time of any measurable amounts. Broadly chance PoP with some likely north carries from Sat into Sun...but it will be likely that one of the days ends up being not so bad as model guidance narrows on a smaller window.

Otherwise the forecast is largely a consensus blend NBM.

AVIATION /22Z SUNDAY THROUGH FRIDAY/
Short Term...Winds will diminish between 22Z and 02Z, becoming light in most places after that. VFR is expected into Monday evening, with some MVFR conds possible in SHRA later Monday night, and can't rule a little IFR at times as well.

Long Term...Conditions will return to VFR Tue as winds turn offshore. Some lingering MVFR CIGs will be possible in the mtns before drier air moves in and clouds scatter out. VFR conditions are expected to continue thru the end of the work week.

MARINE
Short Term...Winds/seas will continue to gradually subside through the evening, and should fall below SCA levels late this evening. Winds then become light through Monday, but will start to pick up from the S late in the day and into Mon evening.
Still they should stay below SCA levels through Monday night.

Long Term...Winds and seas are anticipated to remain below SCA thresholds thru the extended. By next weekend seas outside the bays may build to near 5 ft.

FIRE WEATHER
Winds diminish and RH will increase toward sunset tonight, and this will allow critical fire weather conditions to ease. On Monday will see much lighter winds and and higher RH, so fire weather will not be an issue.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...Small Craft Advisory until 11 PM EDT this evening for ANZ150>154.
