Area Forecast Discussion National Weather Service Gray ME 340 PM EDT Wed Apr 24 2024

SYNOPSIS
Dry high pressure then moves into and across the region tonight through Saturday. A warming trend can be expected over the weekend with chance of showers Saturday night or Sunday. Warmer weather is then expected early next week for most areas except possibly the coastal plain.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/
A cold front will pass through the area through the evening, kicking up some winds as well as dropping temperatures overnight.

After midday clearing, scattered showers have again developed over the area. This is associated with lift from the passing cold front, and should taper into the early evening. Some light snow is also expected through early evening along the US/CAD border. Mixing taps into some low level winds through late evening, creating gusts up to 35 mph. Winds should lose gust factor around midnight, with breeze continuing. Temps fall due to this CAA, with widespread values around freezing or off into the 20s across the mountains.

SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/
Wave that enhanced winds Wed evening will have moved out for Thursday, with just a few gusts early. As mixing kicks in amid a very dry airmass, will likely see RH values fall into the 20s and teens through the afternoon. Limited moisture through the column should prove for a nearly full sun day. Temperatures will be cooler however, and struggle to warm outside of direct sun insolation. HRRR is depicting a seabreeze beginning early afternoon, and this should bring a wind shift to coastal communities around 2pm along with a bit more humidity as temps fall off a couple degrees.

LONG TERM /FRIDAY THROUGH WEDNESDAY/
We'll start off the long term period 12z on Friday with a 1030+ millibar high pressure center overhead. A cool crisp morning will give way to a sunny afternoon but with below normal temperatures.

Deep layer ridging builds Friday night allowing for the fair weather to continue. Radiational cooling is likely Friday night and therefore sided with MOS guidance for lows.

Deep layer ridging slowly moves eastward on Saturday but still should provide for a fair weather day with temperatures returning to the 60s. A warm front approaches from the west Saturday night with the chance of showers late. However, the ridge aloft will hold firm so capped the PoPs some as it's entirely possible that any period of showers Saturday night and Sunday could be brief. It still should remain cloudy Sunday with low level onshore flow in place, but larger scale subsidence should keep chances of rain low.

The same general setup looks to be in the cards for Monday but there is more uncertainty in temperatures as onshore flow may penetrate deeper into Maine and portions of NH. The best chance of 70+ degree readings will be over southwestern NH while lower temperatures are expected as one moves eastward. There is also a chance that some showers will spill over the ridge axis.

The best chance of measurable rainfall will come Tuesday and/or Wednesday as the ridge finally breaks down and allows a trough to approach from the west. Showers and perhaps a few thunderstorms will be possible then.

AVIATION /18Z WEDNESDAY THROUGH MONDAY/
Short Term...VFR with gusty NW winds through mid evening. MVFR ceilings through late this afternoon for HIE. Some gusts may approach 30 kt accompanying showers. Some LLWS is possible as surface winds settle before winds aloft. Winds slowly slacken overnight. Lighter winds Thursday, with primarily SKC conditions. Can't rule out some valley fog developing Thursday night.

Long Term...VFR prevails Friday through Saturday with high pressure overhead. Scattered -SHRA arrives Saturday night through part of Sunday with possible lower ceilings although the any rainfall would likely be brief at one location. The same is expected for Monday although chances of rain will be lower.

MARINE
Short Term...NW winds increase this evening as a cold front crosses the waters. Some gusts to 35 kt are possible, but bulk of these winds should be 30kt or less. These winds slacken below SCA criteria Thursday morning, with seas slowly lowered to 3 to 4 ft through the day. A seabreeze may form during the afternoon, turning winds onshore for the bays/harbors.

Long Term...Winds and seas to remain below thresholds hazardous to small crafts as high pressure builds over the waters Fri-Mon.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...Small Craft Advisory until 8 AM EDT Thursday for ANZ150-152- 154.
Small Craft Advisory from 6 PM this evening to 4 AM EDT Thursday for ANZ151-153.
