Area Forecast Discussion National Weather Service Gray ME 327 PM EDT Sat Apr 27 2024

SYNOPSIS
A warm front will press through northern New England tonight through Sunday bringing intermittent showers and temperatures on on upward trend into Monday. Monday will be warm away from the coast, with cooler temperatures along the coast where the sea breeze develops. Low pressure approaches Tuesday into Wednesday for more widespread showers and cooler temperatures. High pressure will build in for the second half of the week.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
Surface high pressure centered along the southern New England coastline will shift slightly offshore tonight while a warm front over the eastern Great Lakes presses into western New England. This front will bring increasing clouds overnight with chances for showers, mainly over New Hampshire. Lows tonight will be in the low to mid 40s across New Hampshire where cloud cover and increasing dewpoints will limit cooling, while much of Maine drops into the low to mid 30s where air mass will be drier.

SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/
A short wave and associated surface low tracks across northern Quebec Sunday with the warm front making some progress into New Hampshire and far western Maine. Forcing for ascent will be limited as a mid level ridge axis remains near overhead. Nevertheless, there will be some chances for showers across the mountains during the day with shower chances expanding to the coast Sunday evening. Temperatures aloft will rise to around +15C at H9 across New Hampshire resulting in highs climbing into the low 70s. This warm air aloft does not quite get into Maine where highs will be in the 60s across the interior and 50s near the coast.

Relatively quiet weather continues Sunday night with low chances for showers and low in the 40s to 50s.

LONG TERM /MONDAY THROUGH SATURDAY/
----------------------------------------------------------------- Summary:

*Monday looks to be the first 70F+ day of 2024 for a lot of people in southern NH.

*More seasonable Tuesday and Wednesday, with showers moving through in the Tues-Wednesday morning timeframe. Accumulations will be light.

*Tranquil Wednesday and Thursday with warmer temps returning on Thursday and possibly more unsettled weather returning on Friday.
----------------------------------------------------------------- Discussion: A strong upper-level high in Canada will pull apart a mid- latitude system over the Great Lakes. Ahead of this system, ridging will persist and will bring some of the warmest weather we have seen since last Fall. High temperatures above 70F are likely Monday across southern New Hampshire and even possibly as far north as Lebanon or Fryeburg. Temperatures likely return to average after the passage of the front as well as some cold air advection from a quasi- backdoor front stalled over New Brunswick inches westward into Maine.

The remnants of the aforementioned decaying system could bring some showers into the region on Tuesday through Wednesday morning.
Measurable rainfall is possible across southern and western New Hampshire, but any rain totals should be relatively light in nature and not exceed a half inch.

High pressure moves into the region, bringing a tranquil Wednesday and Thursday into the forecast before a similar decaying low brings a few more showers into the area on Friday. Ridging looks to return on Thursday, with 70s briefly returning to the forecast for the end of the week.

AVIATION /19Z SATURDAY THROUGH THURSDAY/
Short Term...Mainly VFR will prevail into tonight. Skies become BKN to OVC tonight with cigs potentially lowering to MVFR thresholds Sunday morning. Sunday will likely see mainly VFR with tempo periods of MVFR cigs as a front brings scattered showers into northern and western areas. Chances for showers continue into Sunday night for more tempo MVFR conditions.

Long Term...
No restrictions expected on Monday with partly cloudy skies and northerly winds expected. Some showers are possible Tuesday through Wednesday morning, with some occasional MVFR expected. Otherwise no notable restrictions expected in the extended forecast at this time.

MARINE
Short Term...Winds and seas remain below SCA thresholds tonight through Sunday night.

Long Term...
Seas of 2-3 ft with 15kt winds expected on Monday. Winds quickly flip Monday afternoon as the sea breeze moves in but winds return to more calmer northerlies in the evening. Northerly winds pick up overnight, peaking at 20kts. An SCA is possible but not expected for Monday night / Tuesday morning. Winds and seas remain below SCA level after Tuesday.

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