Area Forecast Discussion National Weather Service Gray ME 307 PM EDT Wed May 1 2024

SYNOPSIS
Mainly cloudy and raw with an onshore flow tonight. Shower chances return for Thursday. Cloudy skies and onshore winds will favor high temperatures running below normal through the rest of the week. High pressure builds in from the north Friday for mostly fair weather into Saturday. Chances for showers increase Sunday and Sunday night before drier air arrives on Monday. Warmer temperatures are looking likely for the first part of next week.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/
Low clouds continue to persist across much of the area this afternoon with some clearing of skies across northeastern zones.
These clouds are forecast lift briefly through this evening while much of the area remains mostly cloudy. Weak surface high offshore will maintain light onshore flow tonight with clouds expected to lower overnight with patchy fog.

The next short wave to traverse a mid level ridge over the eastern US will approach the forecast area from the NW tonight.
This system will bring increasing chances for showers after midnight across NW zones with showers spreading SE into much of Maine Thursday morning. Lows tonight will generally be in the 40s.

SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/
The approaching short wave and surface reflection will track NW to SE along the NH/ME border during the day Thursday. This system will maintain cloudy and cool conditions across much of Maine with periods of showers throughout the day. On the SW side of this system there will be breaks of sunshine, less chances for showers, and much warmer temperatures. There looks to be a very sharp gradient in temperatures across the area withs highs only near 50 degrees across Maine while portions of SW NH climb into the upper 60s to low 70s. CAMs have been suggesting that there will be some instability that develops within the small warm sector of the system and have included the mention of isolated thunder across portions of central NH tomorrow afternoon. Total QPF for this system will be on the order of 0.25 to 0.5 inches across Maine with higher amounts in the mountains. QPF drops off across southwestern NH with portions of Cheshire County possibly missing out from measurable rainfall.

The compact surface low will push offshore tomorrow evening bringing an end to the showers. High pressure will start to build in from the north Thursday night while skies look to remain mostly cloudy. Lows will range from the upper 30s to low 40s.

LONG TERM /FRIDAY THROUGH WEDNESDAY/
A stubborn moving area of high pressure will be nearly stationary over the Canadian Maritimes. This blocking pattern will continue to bring a raw and chilly fetch of northeasterly winds to the forecast area. Dry conditions will persist on Friday under partly to mostly cloudy conditions which is supported by the latest HRRR solution. Temperatures will reach the 50s along the coast to the lower to mid 60s inland which is actually an improvement.

Similar conditions will continue on Saturday with a light east to northeast flow coming in off the Gulf of Maine. Due to the cold ocean water temperatures, highs will be limited to the 50s along the coast with the chilliest day for highs along the Midcoast region.

By Sunday, a warm front will finally approach from the west.
Warm air advection and increased moisture will allow for scattered showers to cross the region. The greatest chance for precipitation will be during the afternoon hours and continue into the night.

Models suggest any leftover light showers will retreat to the north on Monday, leaving just some early morning cloudiness across the region. Partial clearing will take place as the low level moisture becomes scoured in a westerly flow. The increasing sunshine will allow for afternoon highs in the 60s, however some inland areas may reach the lower 70s.

Dry and seasonably mild conditions will continue on Tuesday before low pressure brings a bout of rain to the region by Wednesday as an active and fast flow sets up.

AVIATION /17Z WEDNESDAY THROUGH SUNDAY/
Short Term...Cigs are currently fluctuating between MVFR/IFR thresholds with the expectation that cigs lift briefly through this evening. Conditions then deteriorate to IFR/LIFR tonight as cigs lower with fog and showers developing towards Thursday morning. Low clouds and showers persist through Thursday mainly impacting KHIE to KPSM and TAF sites in Maine with MVFR to IFR conditions. Farther to the west there will be lower chances for showers and breaks in the cloud cover with KMHT, KCON, KLEB likely seeing MVFR to VFR conditions. A drying trend Thursday night may allow for improving conditions across Maine TAF sites.

Long Term...VFR is the prevailing condition through Saturday, with the next chance for restrictions being on Sunday as ceilings lower and rain showers cross the area. Lowered ceilings continue early Monday morning, otherwise VFR conditions will be developing.

MARINE
Short Term...Winds and seas remain below SCA thresholds tonight through Thursday night. Low pressure tracking NW to SE across the waters Thursday will bring increasing SE flow Thursday morning followed by NE flow Thursday evening with showers.

Long Term...Conditions hazardous to small craft are not expected. A generally light east to southeasterly flow can be expected for much of the long term portion of the forecast.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...None.
