671 FXUS61 KCAR 010541 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 141 AM EDT Mon Jun 1 2026 .WHAT HAS CHANGED... - Increased shower/thunderstorm chances a bit today in the north, with scattered showers and isolated storms. && .KEY MESSAGES... 1) Scattered afternoon showers and isolated storms today and Tuesday. The activity today will be over Northern Maine, and Tuesday will be Downeast. 2) Much warmer Wednesday through Friday, with two dry days in a row area wide Wednesday and Thursday. && .DISCUSSION... KEY MESSAGE 1...Scattered afternoon showers and isolated storms today and Tuesday. The activity today will be over Northern Maine, and Tuesday will be Downeast. KEY MESSAGE 1 DESCRIPTION... Frosty start to the day today in some areas, but this should be the last frosty morning. The main thing to watch today and Tuesday is the potential for afternoon showers/storms. Neither day is looking that impressive, but there should be just enough instability for scattered showers and perhaps an isolated storm both days. Today`s threat is over Northern Maine north of Millinocket, while for Tuesday some drier air moves into the north and focus shifts to near the Downeast coast. No strong/severe storms are expected either day, and it`s possible the showers may not even grow to storms either day. Coverage will be scattered in nature in the north today and near the coast tomorrow, with more areas staying dry than getting wet. Still, if you do have afternoon plans, it`s a good idea to keep an eye and ear to the sky, especially if you happen to get near any of the isolated storms in which case it`s a good idea to take shelter. Temperatures today and Tuesday will be a bit warmer, with mid/upper 60s today and upper 60s to low 70s tomorrow. KEY MESSAGE 2...Much warmer Wednesday through Friday, with two dry days in a row area wide Wednesday and Thursday. KEY MESSAGE 2 DESCRIPTION... A large surface high pressure system centered over the Great Lakes will gradually move southeast from Wednesday through Friday. As the system progresses, WSW flow will bring a very warm and dry airmass from the Southwestern US into the region. This will create clear skies and above normal temps. Wednesday should see mid 70s across the region. Thursday is expected to be the warmest day of the week with temps in the mid 80s. By Friday, the cold front should move through the north. This should bring temps into the mid to upper 70s in the north, but another day in the 80s for the south. && .AVIATION /06Z MONDAY THROUGH FRIDAY/... Mainly VFR through the TAF period from early this morning into Monday night. One thing to watch early this morning is patchy fog especially for GNR/MLT/BGR/BHB. For TAF sites (BGR/BHB), odds of fog are low enough that left out of the TAF. One other potential issue is scattered showers/isolated storms mainly north of HUL this afternoon. Winds today generally light, though a 10 kt sea breeze from the south is expected for BHB/BGR after 19z. Tuesday: Mainly VFR, with chance of afternoon showers/storms mainly at BHB. NW winds around 10 kts with a few gusts 15-20 kts. Tue night-Thur night...VFR. Light and variable winds, then W winds 5-10 kts on Thur. Friday...Mainly VFR, with possible MVFR for KFVE/KCAR/KPQI/KHUL in rain showers by the afternoon. W winds 5-10 kts. && .MARINE... Winds and seas should remain below SCA criteria through Friday. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None. MARINE...None. && $$ DISCUSSION...TF/ARL AVIATION...TF/ARL
