Area Forecast Discussion National Weather Service Gray ME 1101 AM EDT Tue May 7 2024

SYNOPSIS
High pressure builds into the area today along with warm daytime temperatures. Widespread showers move in by the end of on Wednesday with some thunder possible across western NH Wednesday afternoon or evening. Another system follows for the end of the week, bringing the possibility of more showers into the forecast. The unsettled, showery pattern may continue through the weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/
11 AM...Just some quick adjustments based on current obs, but overall forecast remains unchanged. Enjoy the mild and sunny afternoon.

630 AM...No changes to the going forecast. Locally dense valley fog will lift and dissipate early on.

Previously...

Weak high pressure settles over the area today with light winds, mostly sunny skies and temperatures mainly in the 70s. A seabreeze may make it onto some peninsulas, but overall it appears as though opposing flow will keep the the seabreeze largely offshore.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/
Our stretch of warm and fair weather ends tonight as low pressure approaches from the west and a warm front sharpens up to our south. This will aid in increasing forcing for ascent along with a developing easterly flow. This evening will be dry but rain showers will likely move into western zones after midnight as the short wave trough and attendant SFC low pressure center approaches. Rain can be expected for most of the forecast area by mid morning on Wednesday. Not out of the question that a thunderstorm could be embedded within the larger area of rain/showers as steep mid level lapse rates advect in from west aiding in elevated CAPE.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/
Gloomy and showery weather continues as more surface lows move across the region through the end of the week, with this pattern potentially continuing well into next week. However, there is still some model signals that indicate that the weekend will not be a washout.

AVIATION /15Z TUESDAY THROUGH SATURDAY/
Short Term...VFR conditions are expected today with with westerly winds around 10 knots, possibly gusty at times. This should keep the seabreeze away from coastal terminals today, but it's possible that it may briefly affect PWM and RKD late this afternoon. Otherwise, VFR starting out tonight but conditions later on across western NH will deteriorate in rain, with those lower conditions (likely IFR) being widespread by mid morning to early afternoon Wednesday and especially Wednesday night and Thu. Isold thunder possible Wednesday, especially across southern and western NH.

Long Term...
IFR to MVFR conditions are the most likely outcome Thu into the weekend as the weather remains unsettled.

MARINE
Short Term...Conditions remain below SCA levels through Wednesday.

Long Term...
Winds and seas are expected to stay below SCA criteria until Friday morning, when northeasterly winds possibly pick up to 25 kts.
Wave heights increase Friday morning as well and possible SCA seas and winds could continue into the weekend as well.

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