933 FXUS61 KCAR 011841 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 241 PM EDT Sat Nov 1 2025 .SYNOPSIS... Low pressure will track northeast across the Northern Maritimes today. High pressure will build in from the west tonight and Sunday and slide southeast of the area Monday. An occluded front will cross the area Monday night. High pressure will build to our south Tuesday into Wednesday. Low pressure passes south on Thursday. && .NEAR TERM /THROUGH SUNDAY NIGHT/... The large surface ridge will continue to move into the region as the low pressure exits. For tonight, high res models show some moisture still up north due to the remaining vort max exiting the area. Rain showers should complete leave the region by midnight. As the system exits, W winds will gradually decrease throughout the night. Temps will be in the low 30s. By Sunday, the surface ridge will move through New England bringing clearer skies and calming winds. The cooler and drier W winds will bring temps into the mid to upper 40s. && .SHORT TERM /MONDAY THROUGH TUESDAY/... A low pressure trough will cross the area late Monday through Monday night, bringing the next round of rain showers across the forecast area. The bulk of any rain that falls will likely fall late Monday night, though rain totals will be relatively light and not make much of a dent in the ongoing drought conditions. This low pressure trough will also lead to the development of a 925mb LLJ on the back side, contributing to gusty winds late Monday night through Tuesday. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... A narrow ridge of high pressure will return through the middle of the week, followed by another low pressure system approaching from the southwest into the second half of the week. Guidance continues to trend south with the track of this low, though global models have stabilized some after a rapid jump south on previous runs. Current consensus leads to the highest chance for precip being across Downeast, though the north may remain dry in this pattern. That said, the ECMWF has held onto a more central track for this low, which would bring more precip into the northern half of the forecast area as well. This run of the ECMWF also dives south enough for 540dam thickness line to pull far enough south for the north to see some snowfall. But solutions also still exist that the thicknesses are not quite low enough for a change in precip type, and that the north could also just see a cold rain with this event. A tightened pressure gradient may also exist with this storm and a return to gusty winds through the end of the week. In this active pattern, yet another low pressure system could approach from the west into the day on Saturday. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/...
