Area Forecast Discussion National Weather Service Caribou ME 902 AM EST Fri Dec 8 2023
SYNOPSIS
High pressure will cross the area today. A warm front will approach tonight then cross the region Saturday. Intensifying low pressure tracking across Maine will draw a cold front across the region Sunday night into Monday. High pressure builds Monday night into Tuesday.
NEAR TERM /THROUGH TONIGHT/
902AM Update...Most of the clouds have cleared from the region, so adjusted the sky forecast to show this. Otherwise, the rest of the forecast looks good.
Previous Discussion: Mostly clear skies persist across most of the forecast area early this morning, though a few low level clouds remain across northeastern Aroostook county, with occasional flurries found within this patch of stratus. That said, high pressure will continue to provide subsidence to the area, allowing for skies to fully clear for the day today across the entire forecast area. These clear skies will allow for as much incoming solar radiation as possible with the low sun angles this time of the year, but with persistent west to northwest winds advecting cooler air into the region, highs today will only range from the mid 20s across the north to around 30 along the Downeast coast.
Tonight, clear skies are expected to persist through the night, and with recent snowfall across most of the CWA and winds becoming light and variable, radiational cooling will allow for temperatures to drop significantly. Current forecast is assuming completely clear skies everywhere, though it is possible a mesoscale band of stratus could develop off the St.
Lawrence today and remain stationary over parts of northern Aroostook county tonight, which would mitigate the cooling effect. There is moderate to high (77%) confidence in temperatures dropping below zero across most of Aroostook county, while temperatures fall into the single digits above zero to low teens in the Downeast region.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
A very active mid-term. First concern is potential for light freezing rain or freezing drizzle late Sat/Sat night. Second concern is a strong storm system late Sun through Mon with heavy rain, strong wind, coastal flooding, flash freeze, and a small snow potential.
Saturday/Saturday Night...
Decent warm advection from the SW and increasing/thickening clouds. Late in the day and into Sat night, could be enough low level moisture for some light precipitation or drizzle.
Temperatures north of Bangor will be near or just below freezing with very light temps above freezing aloft, leading to the potential for freezing drizzle/freezing rain. Precip amounts look very light...less than 0.05"...but it doesn't take much freezing drizzle or freezing rain to lead to travel impacts.
Think that the best shot at freezing precipitation, if any does occur, is over the Central Highlands. Temperatures Sat night will be slowly warming, with the freezing line creeping north to around the St John Valley at dawn Sunday. The warm advection over the snowpack will likely lead to a fair amount of fog Saturday night.
Sunday to Monday...
A dynamic weather system is in store. High amplitude upper trough will be approaching from the west, with strong southerly fetch. A frontal boundary with a strong temperature gradient will be moving east through the region, with surface low development over Southern New England and rapid intensification as it moves roughly over western Maine Mon morning.
Models/ensembles are in decent agreement, but there are some crucial differences that will determine the ultimate impacts, namely the speed/amplitude of the upper trough and exact track of the surface low that develops and intensifies along the cold front.
Heavy Rain Threat...
There is fairly high confidence, and increasing confidence, in heavy rain. Models/ensembles have been trending wetter, and likelihood is there for 1.5-2.5 inches of rain, with the potential for more. Precipitable water values in some of the wetter model solutions are near all-time record levels for December, with a strong plume of moisture from the south. And there will likely be a front somewhere near us that will be the focus for the heavy rain. While there is some uncertainty where this sets up, likelihood exists for somewhere in the state to exceed 2 inches of rain, with the best likelihood at this time appearing to be over western portions of the forecast area, especially the Central Highlands where orographic lift will play a role. The heavy rain threat is from late Sun afternoon to Mon morning. Adding to the concern is the snowpack that will be melting off with the very mild temperatures and rain. Some smaller river and streams could experience some flooding, but the magnitude is still uncertain this far out. Don't believe there is enough ice on the rivers yet for ice jams to be an issue.
Wind Threat...
The wind threat is conditional on where the surface low tracks along the front. If the low tracks west of our area, the whole area could get strong, impactful winds from the south, but if the low tracks over our area, the wind threat could be limited to eastern portions of the area or even just over New Brunswick.
Odds favor strong wind at least for Washington County, but will continue to monitor.
Coastal Flooding...
Think that coastal flood threat is fairly minor, mainly because the surge of around two feet most likely comes a few hours after the Mon morning high tide. Anticipate perhaps some minor wave runup and splashover issues, but if the system were to speed up and the surge and higher seas were to coincide with the Mon morning high tide, it could be a more serious issue.
Snow...
At this time, majority of models bring the heavier snow west of our forecast area. However, were the front and low pressure to set up further east, as a minority (<25%) of ensemble solutions do show, there could be heavy snowfall mainly over western portions of the forecast area. At this time, the most likely scenario is a brief changeover to snow in the north/northwest toward the end of the event Mon afternoon/evening with perhaps an inch or two of snow.
Flash Freeze...
Roads could become icy Monday night as cooler air moves in behind the system. Confidence in this is low at this time due to uncertainty on the gap, if any, between precipitation ending and temps falling below freezing.
LONG TERM /MONDAY THROUGH THURSDAY/
Quieter weather Tue to Thu, with perhaps a weak system or two in westerly flow. Temps should be fairly close to average.
AVIATION /14Z FRIDAY THROUGH TUESDAY/
NEAR TERM: VFR conditions expected to persist through the day and into the night tonight across all terminals. NW winds 5 to 10 kts becoming light and variable. Slight chance (10%) of low level stratus returning to northern terminals late this afternoon into the night tonight, which would bring the return of MVFR cigs.
SHORT TERM: Saturday...MVFR cigs developing Saturday afternoon. Light winds.
Saturday night and Sunday...IFR to LIFR cigs with IFR vis in fog Saturday night into early Sunday morning. Freezing drizzle is possible Saturday night into early Sunday morning. South winds steadily increasing towards 10 to 20 kt by later Sunday afternoon. LLWS possible by Sunday evening.
Sunday night...IFR to LIFR cigs, IFR to LIFR vis in fog and drizzle, LLWS expected. South winds increasing all night with gusts over 35 kt possible by late night.
Monday...Mostly IFR to LIFR cigs. IFR vis in locally heavy rain.
LLWS continues. South winds possibly gusting over 35 kt in the morning, becoming westerly 15 to 25 kt in the afternoon.
Monday night and Tuesday...MVFR cigs north of GNR and HUL, otherwise VFR. Tempo IFR in snow showers north of GNR and HUL.
West winds 10 to 25 kt.
MARINE
NEAR TERM: Winds and seas will remain below SCA conditions through tonight. Occasional gusts to around 20 kts, especially over the outermost portion of the coastal waters. Seas 1-2 ft.
SHORT TERM: Southerly Gales likely Sun night/Mon, with enough confidence to go ahead and issue a watch. Can't rule out storm force winds. Seas likely to build to close to 20 ft late Mon.
Conditions gradually improve Mon night/Tue as winds shift from S to W/NW.
CAR WATCHES/WARNINGS/ADVISORIES
ME...None.
MARINE...Gale Watch from Sunday afternoon through Monday evening for ANZ050>052.
