Area Forecast Discussion National Weather Service Caribou ME 1114 PM EDT Tue May 7 2024

SYNOPSIS
High pressure will crest over the area tonight. Low pressure crosses the region Wednesday night then exits across the Maritimes Thursday. Another low should track south of the region Friday then exit across the Maritimes Saturday. Another low could approach Sunday.

NEAR TERM /THROUGH WEDNESDAY/
11:10 PM Update...The sky is mostly clear across the area.
Lowered temps a couple degrees early in the overnight period.
Otherwise, no major changes this hour.

Previous discussion...
A shortwave tracking southeastward from Quebec is bringing mostly cloudy skies to the northern half of the forecast area.
This feature is bringing cool air advection, resulting in breezy northwesterly winds. Further south, skies are mostly sunny as the northwest winds downslope off the higher terrain. As the shortwave pulls away into the Canadian Maritimes tonight, skies will clear and winds will diminish. This will mean favorable conditions for radiational cooling, particularly in the northern valleys. Lows across the North tonight will be in the 30s, with colder valleys falling to or just below freezing. Further south, some high clouds will begin to move in towards daybreak. This will keep lows in the lower 40s for Bangor and Downeast.

A low pressure system will begin to approach from the southwest on Wednesday. Thus, clouds will increase from southwest to northeast during the morning. Light to moderate rain will move into areas south and west of Katahdin during the afternoon.
Further north and east, steady rain will likely hold off until the evening. High temperatures will rise into the 50s to near 60 degrees before any rain moves in.

SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/
Surface low pressure crosses the region Wednesday night, exiting across the Maritimes late, with a trof extending back across the forecast area. Aloft, an upper level disturbance also crosses the region. Expect rain Wednesday night, tapering to showers late.
Upper level troffing persists north of the region Thursday, while another disturbance moving around the trof crosses the region. Expect mostly cloudy skies with a chance of showers Thursday. The upper trof should settle south across the forecast area Thursday night, while surface low pressure tracks south of the region. Expect mostly cloudy skies with a chance of showers across northern areas Thursday night. Across Downeast areas, expect a chance of showers though a steadier rain is also possible dependent on the low track. Upper troffing persists across the region Friday, with uncertainty regarding the location of the surface low. Will keep a chance of showers across the region Friday due to the uncertainty. Slightly below normal level temperatures are expected Thursday/Friday.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
Unsettled conditions are expected Friday night through Tuesday with shower chances, along with possible intervals of steadier rain, though the exact details remain uncertain. Uncertainty exists with the timing/track of low pressure Friday night into Saturday which will keep a chance of showers, possibly a steadier rain, across the region. An upper level trof should cross the region Sunday with a chance of showers. The upper trof should exit across the Maritimes later Monday. Expect partly/mostly cloudy skies with still a chance of showers Monday. Low pressure should approach, from the west, later Tuesday. However, timing differences still exist regarding how rapidly the system approaches. Due to the uncertainty, have kept just a chance of showers Tuesday. However, a more rapid approach could allow for a steadier rain. Below normal level temperatures are expected Saturday/Sunday. Near normal, to slightly above normal, level temperatures are expected Monday/Tuesday.
