National Weather Service Caribou ME
1130pm EST Wednesday Feb 21 2024
High pressure will slide east of the area tonight through Thursday. An occluded front will approach Thursday night. Low pressure will develop along the New England coast and Gulf of Maine Friday, then exit across the Maritimes Friday night through Saturday. High pressure will cross the region Sunday. A cold front will cross the region Monday.
Near Term - Until 6pm This Evening
11:30 PMMade some minor adjustments to cloud cover and temps over central areas where a band of low clouds has formed. Otherwise, no major changes were needed this hour.
Previous Discussion... The center of the high pressure system will continue to move out to sea this evening and night. With a low pressure system to the NW and one to the SE, the pressure gradients for the high will stretch over the region, providing southerly flow. These S winds coupled with onshore moisture will develop low level clouds along the upslope sides of the higher terrain from the Central Highlands into southern Aroostook. Due to the very dry air within the dendritic growth zone, these clouds are not expected to develop snow showers, however, it is more likely to develop patchy freezing drizzle. Decided to include patchy freezing drizzle throughout the night and into Thursday morning. In addition, upper air model soundings show a very shallow inversion with the incoming cloud cover, so increased temps slightly to have teens in the north and low 20s in the south.
By Thursday, as mentioned above, patchy freezing drizzle is expected through the morning as the rest of the ridge moves south. Due to dry roads and cold surface temps, freezing drizzle could cause travel difficulty for the morning commute. As the sun angles gets higher and temps increase, the freezing drizzle will dissipate as well as the cloud cover. S winds and sunshine will help increase temps into the low to mid 30s across the region.
Short Term - 6pm This Evening Through Saturday
An area of low pressure tracks to the Mid-Atlantic region Thursday night while a second low tracks to northern Quebec province, with a cold/occluded front extending between the two systems. Clouds will increase Thursday night along with a chance of snow late. The front moves toward the forecast area Friday, while a new low develops along the front across the New England coast and Gulf of Maine. However, uncertainty still exists regarding the exact location where the new low develops. Precipitation develops across the entire forecast area Friday. Based on critical thickness values expect precipitation will generally remain in the form of snow across northern and central areas, though the snow could mix with rain across central areas. The snow should transition to rain Downeast. Have kept precipitation in the form of snow/rain Friday, though a brief wintry mix could also be possible during the time of transition. The slowly intensifying low tracks across the Maritimes to the Gulf of Saint Lawrence Friday night. Aloft, an upper level disturbance also lifts across the region in advance of an approaching trough. Steady precipitation persists early Friday night, then tapers to snow showers. Colder air will be drawn across the region in the wake of the low allowing any rain to transition back to snow before tapering to snow showers. Snow accumulations Friday into Friday night are still uncertain. The low lifts to Labrador Saturday. Expect mostly cloudy skies along with a slight chance/chance of snow showers early Saturday, with clouds then decreasing during the afternoon. Expect above normal level temperatures Friday, with below normal level temperatures Saturday.
Long Term - Saturday Through Tuesday
High pressure builds across the region Saturday night, then exits to the southeast Sunday. Expect mostly clear/partly cloudy skies Saturday night through Sunday. Clouds increase Sunday night with a slight chance of snow showers late in advance of an approaching warm front. The warm front should cross the region early Monday, with a cold front then crossing late. Expect mostly cloudy skies along with a chance of snow showers north, a chance of snow/rain showers Downeast. High pressure should cross the region Monday night, then move to the east Tuesday. A warm front should then begin to approach later Tuesday with the developing return flow of warmer air. Overrunning precipitation should develop Tuesday night. Based on preliminary critical thickness values, precipitation Tuesday night could start in the form of a wintry mix or snow then transition to toward rain. The warm front should cross the region early Wednesday. Current indications are for precipitation in the form of rain or rain showers Wednesday. Expect near normal level temperatures Sunday. Increasingly above normal level temperatures are then expected Monday through Wednesday.
Near Term: Winds and seas remain below SCA (Small Craft Advisory) levels tonight and most of Thursday. By Thursday afternoon into Thursday evening, seas increase, reaching SCA (Small Craft Advisory) levels by the late evening.
Short Term: Small craft advisory conditions possible later Thursday night into Friday. Gale force wind gusts possible Friday night into Saturday. A chance of rain/snow Thursday night. Rain Friday through early Friday night, with a chance of snow showers later Friday night. A chance of snow showers early Saturday. Light freezing spray Saturday.
