109 FXUS61 KCAR 092224 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 524 PM EST Sat Nov 9 2024 .SYNOPSIS... High pressure will build south of the area tonight. A warm front approaches Sunday night and passes through on Monday, followed by a cold front on Tuesday. High pressure returns on Wednesday. && .NEAR TERM /THROUGH SUNDAY/... 519 pm update...Skies have cleared and winds continue to slowly diminish. High pressure builds well south to the area, so do not expect winds to diminish enough to warrant any reductions in lows tonight. Warming southwest winds will be in place Sunday as high temps are around 10F warmer than today. Previous discussion... A few flurries will continue acrs the northeast this afternoon and have added those into the fcst. High pressure will slowly build in from the west with winds dropping off this evening. With clear skies and fairly light winds temps look to drop below frzg everywhere, with most locations in the lower 20s. High moves offshore to our south in the morning with winds backing around from the southwest. Sunny to mostly sunny skies will see clouds increase from the west as the last vestiges of the sun shines tomorrow. This will be enough to boost temps toward 50 degrees tomorrow. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... Surface high pressure will continue to drift southeast and out into the open atlantic Sunday night in advance of the next upstream short wave. The flow becomes more south to southwest with time late Sunday night with weak warm advection in the 850 to 700 MB layer. Expect increasing clouds Sunday evening. Some light rain is likely well after midnight for the Bangor region and Downeast. Across the far north, it will take longer for the low levels to moisten up, thus it will likley remain precipitation free much of Sunday night for Northeast Aroostook county. Short wave exits east later Monday morning, with weak surface low tracking to our north north. Expect a continue chance for rain across the north but decreasing chances for Bangor and Downeast. Afternoon highs on Monday range from the low to mid 40s north and mid to upper 50s for Bangor and Downeast. Monday night the next upstream trof approaches from the west with a cold front crossing the region late. Expect the chance for showers, especially across northern areas. Tuesday will be turning colder and it will be blustery. The cold advection in the wake of the front may result in scatterd snow showers or flurries across northern areas. The bigger story will be the increasingly gusty northwest winds with the tightening pressure gradient between low pressure exiting across the Canadian Maritimes and high pressure to the west. Gusts as high as 35 to 40 mph are possible, especially across the higher terrain. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... High pressure builds toward the region Tuesday night through Wednesday. Expect a gusty northwest wind to continue Tuesday night with the surface ridge axis still off to the west. Lows Tuesday night are expected to be in the low to mid 20s with a north to northwest breeze making it feel even colder. A dry and mainly sunny day is expected on Wednesday with diminishing winds. Mainly clear skies Wednesday evening will be followed by increasing late night clouds. Lows Wednesday night will fall into the upper teens across the north and lower 20s for Bangor and Downeast. Thursday through Saturday, still some uncertainty, but it appears high pressure may be the dominant feature into next weekend. Afternoon highs will generally be a bit below normal through the period. && .AVIATION /22Z SATURDAY THROUGH THURSDAY/... NEAR TERM: VFR next 24 hours. Gusty winds will come to an end by 22z, become light and variable overnight and then become light out of the southwest on Sunday. Cannot rule out a mid deck of clouds moving through northern Aroostook terminals late tonight. SHORT TERM: Sun night through Mon...VFR through midnight, then MVFR/IFR in light rain. Mon night...MVFR. Scattered rain showers. Tue through Tuesday night...VFR/MVFR. Scattered snow/rain showers. NW wind gust to 40 kt possible. Wed through Thu...VFR. && .MARINE... NEAR TERM: Winds have diminished below gale force and have issued an SCA as winds will gust to 30kts on the intracoastals into this evening and remain elevated over the outer waters tonight. Expect winds diminish below small craft levels before midnight. Marginal southwest winds will pick up again tomorrow afternoon over the outer waters but confidence is low. Seas drop below 5ft this evening and remain between 1 to 3 feet tomorrow. SHORT TERM: Winds/seas may approach SCA conditions in the SW flow Sunday night and Monday. There is an even better threat of SCA conditions, possibly even gales, Tuesday and Tuesday night in the NW flow behind a cold front. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None. MARINE...Small Craft Advisory until 10 PM EST this evening for ANZ050- 051. Small Craft Advisory until 7 PM EST this evening for ANZ052. && $$ Near Term...Buster Short Term...TWD Long Term...TWD Aviation...Buster/TWD Marine...Buster/TWD
