977 FXUS61 KCAR 060153 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 953 PM EDT Thu Jun 5 2025 .SYNOPSIS... A cold front crosses the region tonight. The front will stall across the Gulf of Maine tonight into Friday. Low pressure will cross the area Saturday followed by high pressure on Sunday. An upper level low will set up to the west of Maine for Monday into early next week. && .NEAR TERM /THROUGH FRIDAY/... Update... Weak boundary will continue to sink down across the area overnight and is just about to the Bangor region. Latest radar reflectivity imagery shows just some isolated showers and thunderstorms moving east along the boundary across interior Downeast areas at this hour. These will wane over the next few hours. Otherwise, expect partly to mostly cloudy skies with some patchy fog overnight. Lows will range from the mid 50s across the north and upper 50s to lower 60s for the bangor region. previous discussion Front that just passed through Maine is going to stall in the Atlantic, as a low pressure develops to our NW. Looking at some clear skies in the north, with some haze, until clouds move back over the region by afternoon. Some shortwave activity in the Penobscot/Bangor and Downeast region will cause some light rain showers. Max temperatures in the upper 70s tomorrow. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... Zonal flow will be shifting to a more swrly flow as upr trof digs into Quebec. Boundary will be sitting over the area with waves riding along it. At this time it appears the best chance for rain will be late Friday night into Saturday morning. Med range guidance, including the latest GFS/CMC and EC, has cold front dropping south out of Canada in the afternoon. Cannot rule out tstms in warm and humid airmass ahead of the front and will continue with this idea. Latest NAM on the other hand appears to be suffering from convective feedback as tightly wound low heading off of the Delmarva Saturday evening is impacting fropa, including keeping showers in longer and winds out of the northeast. Have disregarded this solution as majority of operational and ensemble model solutions do not show this. Showers will wind down Saturday evening, pulling east into New Brunswick by Sunday morning. Skies will be clearing after midnight with lows dipping into the 40s over the North Woods with locations elsewhere dropping into the lower 40s. High pressure will keep sunny conditions over the area on Sunday with highs around to slightly above normal in the 70s. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... High pressure will remain over the region into early next week. Cannot rule out an isolated shower moving in Monday afternoon but depending on the strength of the ridge and the slow movement of the digging upper low, precip may hold off until Tuesday morning. System looks to move fairly quickly as wave opens up aloft and zips through on Tuesday evening, though given discrepancies have gone with likely pops thru the day Wednesday. Showers look to continue in wrap-around northwest flow thru the end of the period. && .AVIATION /02Z FRIDAY THROUGH TUESDAY/... NEAR TERM: KFVE/KCAR/KPQI/KHUL: Mainly VFR through Friday.
