| Area Forecast Discussion National Weather Service Gray ME 613pm EST Fri Nov 13 2026 .WHAT HAS CHANGED... No major changes were needed this Friday evening. .KEY MESSAGES... 1. Cooler conditions prevail through the weekend with chances for snow showers mainly in the mountains. We will then gradually warm back to above normal temperatures next week. KEY MESSAGE 1 DESCRIPTION... Broad upper level troughing currently remains in place over the eastern CONUS with an upper low to our south near the Great Lakes, and another upper low to our north over east central Quebec. The Great Lakes low will gradually drift east southeast through the day before it becomes absorbed in the parent trough. The Quebec low will then dumbbell down into southern Quebec tonight and into northern New England on Saturday/Saturday night. This pattern will lead to slightly below normal high temperatures through the weekend but lows will be well below normal for most areas, mainly in the 20s. This pattern will also lead to periodic snow showers around and north of the mountains on Saturday and Sunday. Saturday/Saturday night will likely see the best coverage as that is when the upper low should move overhead. Any accumulations should remain light but a few of the higher peaks could see an inch or two, especially across northern New Hampshire and northwest Maine. The upper low and trough will finally start to push east on Sunday which will lead to diminishing precipitation chances by the afternoon and evening. Ridging then starts to nudge to begin the work week, which will lead to a gradual warming trend back to above normal temperatures. On Monday, highs will mainly range from the upper 30s to upper 40s, but we will be back to widespread highs in the upper 40s to upper 50s by midweek with a few lower 60s possible across the south. With high pressure dominating, next wee should remain dry. The next trough may approach at the end of the week into next weekend but nothing looks impactful at the moment. Marine Winds and seas will continue to relax through the rest of today and tonight. Then the next potential SCA (Small Craft Advisory) conditions arrive Monday with the passage of a weak cold front and northwesterly winds becoming breezy in its wake.
