018 FXUS61 KCAR 140420 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 1220 AM EDT Sat Jun 14 2025 .SYNOPSIS... High pressure will build across the region through the weekend while low pressure remains south of Maine. High pressure will move east of the region Monday into Tuesday. && .NEAR TERM /THROUGH TODAY/... Update... Latest satellite imagery shows high cloud streaming across the area with the exception of far northern Maine. Current temperatures were generally ranging from the low to mid 40s north, to near 50 degrees in the Bangor region and Downeast. The current forecast remains on track and no changes made at this hour. Previous Discussion... Patchy frost is possible tonight in the normally colder valleys in the North, especially in the North Woods. Decided to highlight the potential in the Hazardous Weather Outlook in northwestern Aroostook County. Not enough confidence for a frost advisory at this time. A few showers are possible at the Downeast Coast for Saturday morning thanks to the aforementioned low. Otherwise, expect a dry day with partly to mostly sunny skies and light winds. High temperatures will be well into the 60s inland. Afternoon sea breeze development will keep temperatures in the 50s to lower 60s. && .SHORT TERM /TONIGHT THROUGH MONDAY/... High pressure will slide eastward Saturday night, bringing the opportunity for a weak shortwave to move through on Sunday. This will cause some afternoon showers, but nothing widespread or significant. After the shortwave moves through, flow will become more southerly, bringing the marine layer in over Downeast. This will cause some fog to build in along the coast for early Monday morning. Temperatures will gradually warm through the period, becoming more seasonable in the low to mid 70s on Monday. Coastal temps Downeast will remain cool, with the influence from the Gulf of Maine. Temperatures Saturday night and Sunday night will remain fairly chilly, in the mid 40s. By Monday afternoon, the pattern will become more unsettled with winds turning more southerly. This will increase temperatures and humidity across the area in advance of an approaching low pressure system. Showers will develop from the southwest during the day, spreading across the whole of northern Maine by the evening. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... The unsettled pattern will continue through Thursday, when a cold front will cross the area. Ahead of this front, several troughs will move through, bringing periods of showers. The timing of these troughs is uncertain at this point, and timing will also be key in determining whether thunderstorms will develop along with the showers. On Tuesday and Wednesday, thunderstorms will be more likely to develop in the afternoon, with diurnal influences. This may also depend on how much clearing occurs during the day. By Thursday, the approaching front will increase instability and widespread thunderstorms are most likely ahead of the front. Details are too hazy at this point to determine the exact nature of the storms, so the pre- storm environment will need to be watched as it develops over the next several days. Friday remains very uncertain with high variability in the forecast models as to whether the low lingers in the area or is pushed out by a weak ridge. Therefore, confidence is low in the end of the forecast period. && .AVIATION /04Z SATURDAY THROUGH WEDNESDAY/... NEAR TERM: Generally VFR across the region overnight through Saturday. However, occasional MVFR possible along the Downeast coast mostly Saturday morning with isolated/scattered showers. Light and variable winds overnight. Variable winds 5 to 10 knots Saturday. SHORT TERM: Saturday Night and Sunday...Mainly VFR. Winds light and variable Saturday night, becoming SW 5-10 kts Sunday. Sunday Night through Tuesday...Mainly VFR north of BGR. However, BGR and especially BHB will be susceptible to IFR ceilings in the overnight and early morning hours, with generally VFR conditions in the afternoons. MVFR possible in showers Monday through Weds, with isolated TS possible Tues and Weds. S-SW winds 5-10 kts. && .MARINE... NEAR TERM: Winds/seas below small craft advisory levels overnight through Saturday. Scattered showers mostly Saturday morning. SHORT TERM: Winds and seas will remain below Small Craft Advisory levels through this weekend and into early next week. Wave heights 1 to 2 feet this weekend, building to 2 to 4 feet early next week. Fog possible over the waters from Sunday night onward. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None. MARINE...None. && $$ Near Term...TD/Clark Short Term...LF Long Term...LF Aviation...Clark/LF Marine...Clark/LF
