Area Forecast Discussion National Weather Service Caribou ME 546 PM EST Tue Dec 5 2023

SYNOPSIS
High pressure will build over the region tonight into Wednesday as low pressure passes well to our south. High pressure will remain over the area Thursday into Friday. A warm front will lift north of the area Saturday. A large area of low pressure will begin to lift up to our west on Sunday as a strong cold front approaches.

NEAR TERM /THROUGH WEDNESDAY/
5:46PM Update...Challenge tonight will be keeping up with the rapid temperature drops across the FA. Temperatures are already falling back into the single digits across northern areas.
Presque Isle is already down to 9F. As winds go calm with fresh snowpack and clear skies expect rapid temperature drops across the north. Low to mid clouds remain in place from Baxter southward with gradual clearing expected tonight. Minor tweaks to try and get the temperature trend with mixing in some NBM 10th percentile to lower the lows a couple degrees especially in Northern areas. Down to below zero in spots.

Previous Discussion...
Isolated snow showers streaming into the area from the north will continue to decrease in number this evening as the sun sets, decreasing instability over the St. Lawrence River and allowing for skies to clear. As skies clear from north to south and with light winds and setting sun, radiational cooling will begin to take full force, allowing for temperatures to rapidly drop through the first half of the night. The only mitigating factor will be high level stratus streaming into the area from the south as a low pressure system passes well to the south of the area. Forecast low temperatures are in the single digits above zero across the north and lower teens closer to the coast, with some sub-zero temperatures in colder areas in the North Woods. These low temperatures could be colder if clear skies last longer, or warmer if cirrostratus moves in earlier than forecast.

Light northwesterly winds will remain into the day on Wednesday, continuing to advect in cold temperatures. Though skies will begin to clear once more under high pressure, the cold air mass in place will keep temperatures well below average, with highs in the 20s across the forecast area for the day on Wednesday.

SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/
High pressure will continue to build in from the west Wednesday night as low pressure off the Mid-Atlantic coast slides out to sea well to our south and east. This will bring a cold night with partial cloudiness over the north where a bit of moisture in the Maritime trough will still stray across, and a mostly clear sky Downeast. Inland lows will drop between 5 and 10 across most of the area. A narrow ridge of high pressure will remain over the region on Thursday bringing a dry day with a light NW flow. Thursday will be cold with lows from the low 20s northwest to the upper 20s Downeast.
This narrow ridge of high pressure, between an upper trough well to our northeast and an approaching warm front and ridge to our southwest, will remain across the area Thursday night. The sky will be mostly clear and winds will be even lighter so lows will be in the low single digits to near zero in some of the northwestern valleys under a mostly clear sky.

LONG TERM /FRIDAY THROUGH TUESDAY/
High pressure will remain over the area Friday bringing a mostly clear sky. However, some high clouds will likely begin to increase Friday afternoon ahead of a warm front extending southeast of a low in Ontario. Clouds will continue to increase Friday night from weak mid level warm advection as the warm front lifts north. The low in Ontario will quickly lift away to the north on Saturday. Meanwhile, a new low supported by a vigorous southern branch trough will be intensifying in the lower Mississippi Valley. High pressure will remain over our region Saturday with the sky remaining mostly cloudy under weak mid level warm advection flow. Low pressure from the Mississippi Valley will quickly lift north into the Great Lakes Saturday night into Sunday. An approaching front being pulled east beneath this low will combine with high pressure well off the coast to bring an increasing southerly breeze on Sunday. The moist southerly flow will continue to bring a mostly cloudy sky. Sunday will turn out must warmer with highs well into the 40s north and low 50s Downeast as warm advection from the south strengthens. The approaching cold front will bring an increasing southerly wind on Sunday. Wind advisories may be needed Downeast for late Sunday or Sunday evening.

A large area of low pressure lifting into Ontario Sunday night will pull a strong cold front into the area. A wind advisory will likely be needed Downeast and may briefly be needed further north ahead of the front for the strong south winds. A band of moderate to heavy rain will likely accompany the front late Sunday evening. Rain amounts of a half inch to a inch are possible, with the heaviest rain in the upslope areas of the central highlands. However, other than some ponding in low lying areas, flooding issues are currently not anticipated with the ice still too thin on the rivers to cause appreciable ice damming, and the band of rain moving through very quickly keeping heavy rain brief. By mid morning Monday, the front should be through, the sky clearing, and winds shifting around to the southwest. Monday will bring partial clearing from south to north with a strong gusty southwesterly wind behind the front. Temps will still be a bit mild with highs in the low 40s north to upper 40s Downeast as the low quickly lifts up and away.
