Area Forecast Discussion National Weather Service Gray ME 321 PM EDT Thu May 2 2024

SYNOPSIS
Rain showers and a few claps of thunder will diminish this evening as a short wave exits the region. Drier weather returns Friday into Saturday, however the pattern remains unsettled and humid with increasing clouds and more showers late in the weekend. The upcoming work week starts on a drying, clearing, and warming trend.

NEAR TERM /UNTIL 7 AM FRIDAY MORNING/
Mesoscale models suggest low pressure will exit southeast through southern New Hampshire late this afternoon and this evening. This will allow for the precipitation to diminish and exit off the coastline and into the Gulf of Maine. The latest HRRR suggests a couple thunderstorms will be possible as well in a highly sheared environment.

The large differences in temperatures from southwest to northeast across the forecast area will continue early this evening prior to all areas dropping into the 40s by late tonight. Areas of fog will develop with the most fog in Maine.

SHORT TERM /7 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/
More low cloud cover and patchy fog will continue Friday morning across the region, especially over eastern portions of the forecast area. A large and persistent area of high pressure will remain entrenched over eastern Canada allowing for the easterly flow off the Gulf of Maine. It will continue to be cool with highs in the 50s along the coast and lower 60s across the interior.

Profiles suggest plenty of low level moisture will continue into Friday night. Patchy fog will develop once again with temperatures dropping into the 40s.

LONG TERM /SATURDAY THROUGH THURSDAY/
Overview: Mid-level ridging will build over the region Saturday through Sunday but temperatures will remain on the cool side due to high pressure located to our east, resulting in onshore flow. Scattered showers will become increasingly likely by Sunday afternoon through the night before a cold front crosses on Monday. Behind this front, westerly winds will allow for warmer temperatures through Tuesday. A passing weak wave of low pressure will allow for an increased chance for showers towards the middle to end of next week.

Impacts: No major weather related impacts expected.

Forecast Details: Mid-level ridging and positive h5 height anomalies will persist Saturday through Sunday. Despite this, surface high pressure to our east and associated clockwise flow will result in onshore winds and a continuation of cool and at times damp conditions. Saturday should remain dry through the daytime hours but remain mostly cloudy with highs ranging from the 50s to middle 60s (coolest along the coast and warmest towards the CT River Valley). Shower chances will then increase on Saturday night through much of Sunday night as a warm front lifts northward. Lows will be primarily into the 40s with highs on Sunday into the 50s.

A cold front will then cross on Monday, bringing an end to the cool and cloudy conditions. Cloudy skies during the morning will become partly cloudy by the afternoon with a drying westerly wind. The additional sunshine will likely allow highs to reach the 60s to middle 70s in most locations. Warm and partly cloudy skies look to continue on Tuesday with highs potentially a few degrees warmer. Shower chances and cooler temperatures then look like they may make a return towards the middle to end of next week as a weak wave of low pressure crosses either over or near New England.

AVIATION /19Z THURSDAY THROUGH TUESDAY/
Short Term...Areas of IFR and LIFR conditions expected tonight in fog and lowered ceilings. Conditions slowly improve with fog gradually lifting on Friday but remain with IFR conditions at most sites in low ceilings. IFR conditions will persist through Friday night with some LIFR locations in fog as well.

Long Term...Mainly VFR conditions are likely Saturday through Sunday morning, although onshore flow may result in some lower ceilings across coastal TAF sites. Scattered -SHRA along with lower ceilings may result in additional restrictions areawide late Sunday through Sunday night before improving back to VFR on Monday morning as southerly winds become westerly behind a cold front.

MARINE
Short Term...A light northeast flow will continue over the area as a large ridge of high pressure remains over eastern Canada tonight through Friday night. A light southerly flow may develop during the afternoon hours on Friday.

Long Term...Southerly winds will become westerly behind a cold front on Monday but likely remain below 25 kts. Seas will be between 1-3 ft, highest outside of the bays.

GYX WATCHES/WARNINGS/ADVISORIES
