105 FXUS61 KCAR 010609 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 209 AM EDT Mon Sep 1 2025 .SYNOPSIS... High pressure remains over the area tonight through Tuesday. An upper level disturbance will cross the region Wednesday. High pressure will cross the region Thursday. An occluded front will begin to cross the region Friday. && .NEAR TERM /THROUGH TUESDAY/... Quiet weather persists through Tuesday as high pressure remains overhead. Expecting fog to dissipate this morning with sunrise, leading to a mostly sunny day across the area. Tonight, clouds will increase ahead of a front approaching mid-week. This may limit the amount of fog forming overnight and into tomorrow morning. A very slim chance of showers exists tomorrow afternoon for the western border with the approach of an upper level trough from the west. Overall, winds will remain light during the period. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... Tuesday night: The mid level trof will track NE across the Quebec. The shortwave energy from this system is expected to produce cloudy skies in the north. This should keep temps in the mid 50s across the region. Wednesday: The mid level trof should move across the region bringing showers across the north. The warmer airmass and S flow should help increase instability in the afternoon. Some isolated to scattered thunderstorms are possible. Expect temps in the upper 70s across the region. Wednesday night: The trof should exit by the evening, with any lingering showers ending before midnight. Very brief high pressure is expected to move in and clear out clouds for the night. Though the skies should be clear, the S flow and evening clouds should keep temps in the low 50s. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... A large occlusion over the Great Lakes is expected to move to the NE through the end of the week. This system is expected to move a cold front through the region by Friday. The extend models still have inconsistencies with the timing of the front. The Canadian model starts rain Friday morning while the GFS and Euro show rain starting in the evening. In addition, the GFS has the rain ending by Saturday while the Canadian and Euro has continuous rain throughout the weekend. Decided to stick with the NBM and have rain end on Sunday. Expect warm temps on Thursday, then cooling after the front passes. && .AVIATION /06Z MONDAY THROUGH FRIDAY/... NEAR TERM: Fog remains the main aviation challenge for the next 24 hours. Some patchy fog has formed around the region tonight, and with T/Tds very close at PQI, CAR, and HUL, saw no reason to remove it from the TAFs. FVE is a little drier and with higher elevation, is likely to miss any valley fog forming. Otherwise, VFR conditions for the next 24 hrs. With higher level clouds moving in overnight, confidence in valley fog forming tomorrow morning is lower. Winds will remain light for the next 24 hrs. SHORT TERM: Tue night...MVFR/IFR in patchy fog. Otherwise, VFR. Slight chance of an afternoon shower northwest. Light and variable winds. Wed-Wed night...MVFR/IFR in afternoon rain showers, then VFR Wed night. WSW winds around 5 kts. Thursday...VFR. S winds 5-10 kts. Thur night...VFR early. MVFR/IFR late in rain showers. S winds 5-10 kts. Friday...MVFR/IFR in rain showers. S winds 10-15 kts with gusts up to 25 kts. && .MARINE... NEAR TERM: Winds and seas will remain below SCA conditions through the near term. Seas generally 3 ft or below over all waters. Light northerly winds this morning will shift clockwise throughout the day on Monday becoming NE Monday afternoon. SHORT TERM: Winds and seas will remain below SCA levels through this period. && .CAR WATCHES/WARNINGS/ADVISORIES...
