535 FXUS61 KCAR 091010 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 610 AM EDT Wed Apr 9 2025 .SYNOPSIS... Low pressure will exit across Nova Scotia this morning. High pressure will build across the region this afternoon into Friday. Low pressure will slowly lift north toward the region through the weekend. && .NEAR TERM /THROUGH TONIGHT/... 6:10 AM Update...Snow showers continue to be scattered across central areas with more isolated snow showers elsewhere. Raised temps a degree or two early this morning and modified sky cover a bit. Otherwise, forecast remains on track. Previous discussion... The small storm system which brought some snow to the area, mostly over the western highlands, will slide east and away early this morning. Any lingering snow showers from the system will taper off early this morning. High pressure will begin to build south of the region this afternoon allowing morning clouds to give way to a partly sunny afternoon. Forecast soundings are showing steep lapse rates up to 8K ft, mainly across the north, and the HRRR is indicating some light scattered snow showers may pop up this afternoon. Will include isolated snow showers over central and northern areas midday into the afternoon. Tonight will turn out mostly clear, moonlit and cold with inland lows near 20 over the region. Winds will become very light westerly as high pressure continues to settle to our south. && .SHORT TERM /THURSDAY THROUGH FRIDAY/... High pressure ridges across the region Thursday with a mostly sunny morning, then a mostly/partly sunny afternoon. Ridging extends from the Maritimes, across the forecast area, to Quebec province Thursday night. At the same time, a trof will extend across New England from low pressure across the Mid-Atlantic region. Expect increasing clouds Thursday night. Ridging persists Friday, with precipitation struggling to expand north from the Mid-Atlantic low. Expect mostly cloudy skies Friday, could also have a slight chance of rain/snow showers. Moisture from the Mid-Atlantic low begins to slowly expand north toward the region Friday night. However, uncertainty still exists regarding how rapidly this occurs. Generally expect precipitation will remain southwest of the region Friday night with skies remaining mostly cloudy across the forecast area, though precipitation could begin to approach southwest portions of the forecast area late. Expect near normal level temperatures Thursday/Friday. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... Precipitation will begin to slowly expand across the forecast area Saturday, though how rapidly this occurs remains uncertain. Generally expect precipitation in the form of rain, though an initial rain/snow mix is possible if precipitation arrives early enough. The vertically stacking surface/upper lows move northeast Sunday, though the track remains uncertain. At the same time, surface/upper ridging will approach from the west. A more northerly low track would keep a chance of rain across the entire region through Sunday into Sunday night. A more southerly low track, would limit rain chances to mostly Downeast areas. The vertically stacked system should slowly exit across the Maritimes Monday, while high pressure begins to build across the region from the west. Could still have a slight chance/chance of rain showers Monday with the exiting system. High pressure crosses the region early Tuesday. Another system could approach later Tuesday. However, whether this system is just a front or a more organized low remains uncertain. Have included a chance of rain showers Tuesday. Expect near normal, to slightly above normal, level temperatures north Saturday. Expect slightly below normal level temperatures Downeast. Expect near normal, to slightly below normal, level temperatures across the entire region Sunday. Expect slightly above normal level temperatures Monday/Tuesday. && .AVIATION /10Z WEDNESDAY THROUGH SUNDAY/...
