Area Forecast Discussion
National Weather Service Caribou ME
1123pm EDT Sunday April 21 2024

Synopsis
A vigorous cold front will cross the area late tonight into Monday morning. High pressure then crests over the region into Monday afternoon, then slowly slides to the east into Tuesday. Low pressure will approach Tuesday night, cross the area Wednesday, then slowly exits into the Maritimes through Thursday. High pressure builds in from the west for Friday.

Near Term - Through Monday
11:20 PMThe sky is mostly clear across weatern areas and mostly cloudy north and east. Mesoscale models continue to agree on the cold front arriving after midnight and possibly bringing a snow shower ahead of it between 1 and 3am across the north. Best chance for snow showers will be in the northwest will any shower activity diminishing as the front pushes across to the east. Forecast looks good. Only some minor changes to temperatures were made.

Prev discussion blo... A vigorous cold front will cross the area overnight tonight with much colder modified arctic airmass. Tonight, expecting the diurnal showers to weaken and dry up but surface lift induced showers will kick off ahead of the front mainly impacting northern areas with rain turning to snow. The best chance at a dusting of snow will be across the Crown down to perhaps the northern Baxter region. Temperatures tonight will crash behind FROPA and fall back into the low to mid 20s across the north with upper 20s to 32F in the Central Highlands and low 30s along the coast. Tomorrow, a very dry airmass but cold airmass will move in with temperatures struggling to recover during the day. Skies will turn full sunshine but highs under strong cold air advection will only top out in the low to mid 30s across the north, low to mid 40s across southern areas given the NW downslope winds off the Longfellow Mtns. NW winds will be gusty 20-30mph across the area. Relative humidity will be very dry in the 20-25% range across the area. Given the winds, low RHs and cold temperatures not entirely too worried about fire weather but still needs to be monitored.

Short Term - Monday Night Through Wednesday Night
Monday Night... Surface high pressure will be centered over the Gulf of Maine Monday night. Skies will be mostly clear. Conditions aren't looking quite as good as they had been for a good radiational cooling night, as there will be an increasing pressure gradient through the night mainly in Northern Maine that could lessen the decoupling. Still expecting cold temperatures...just not terribly cold. Going for lows in the 20s, coolest in valleys.

Tuesday... Surface high pressure moves off to the east and next system begins to approach from the west. Still a good amount of sun. Expect an increasing south breeze with gusts around 30 mph in the afternoon. Much warmer than Monday as well, especially in the north, with upper 50s in the north and low to mid 50s Downeast. Relative humidities will be quite low in the afternoon, mainly in the mid 20s to mid 30s, and coupled with the south breeze, any fires that begin could get out of control in a hurry.

Tuesday Night... Clouds continue to increase from the west as the next system approaches, with skies becoming cloudy. Most precipitation should hold off until during the day Wednesday, though it could begin to enter extreme NW Maine late in the night. Airmass should be warm enough for rain at the onset late Tuesday night in NW Maine.

Wednesday and Wednesday Night... The main period of concern is Wednesday/Wednesday night. An upper trough will be diving SE out of James Bay and cutting off as a strong upper low as it moves roughly over Maine late Wednesday. Much colder air will move in some time Wednesday afternoon or evening as the upper low passes by. A surface low may intensify just to our east Wednesday evening. Looking like a very dynamic situation. There is still a good amount of model uncertainty, but models are in a lot better agreement than they were 24-48 hours ago and seem to be converging on an upper low track and evolution of the system that is conducive for us to get at least a little accumulating snow in the north. If this happens, the rain would transition to snow from west to east Wednesday afternoon and evening before tapering off later Wednesday night or Thursday morning. It is a bit early to talk accumulations, but totals over 3 inches are possible mainly over the northern half of the area. Roads could also freeze Wednesday night for some areas as the colder air moves in with roads remaining wet when temperatures fall below freezing.

Long Term - Thursday Through Sunday
Blustery and cool Thursday as the system exits to our east. Could be a few remaining rain/snow showers mainly in the north. High pressure builds in Friday/Saturday with warmer temperatures and dry conditions. Next rain chance comes around Sunday.

Marine
Near Term: Tonight SW winds shift W generally less than 20kt. Seas generally 2-4ft with a wave period of 6-7sec. Tomorrow AM an Small Craft Advisory in effect for NW winds gusting up to 25kt with seas 3-4ft and a wave period of 5-6sec.

Short Term: Small craft winds/seas expected late Wednesday through early Thursday, with S winds switching to the W. Otherwise, conditions mainly less than small craft through the period.
