| Area Forecast Discussion National Weather Service Gray ME 726pm EST Fri Nov 7 2025 Synopsis A cold front will approach the area tonight with some light precipitation expected. We say precipitation because some of that will fall in the form of snow and maybe a wintry mix in the mountains. A breezy Saturday will give way to increasing clouds and a stronger storm system Sunday. Outside of some mountain snow, it will mostly be a cold rain across the area. A much stronger cold front crosses the region Tuesday. Gusty northwest winds will usher in a colder air mass and temperatures are likely to remain in the 40s during the day for the rest of the week. Near Term - Until 6am Saturday Morning 725 PM...Have mainly refreshed temperatures and Probability of Precipitation based on latest observations as precipitation expands east across the area. Area webcams across northwest Maine show a decent burst of snow has moved across the mountains with a coating of snow down to the valleys. Warmer air aloft will continue to push northeast across the area that will result in snow changing to a wintry mix across the north and then rain by midnight. Previously... A shortwave moves in from the west this afternoon, bringing a cold front across the region. Model guidance has consistently shown a much drier trend with the passing front, with no more than a quarter of an inch of rain expected. The front passes the region late at night, with most of the precipitation out of the area by early Saturday morning. Some front end wintry mix / snow is also possible north of the mountains this evening, though no more than a coating of snow/sleet is expected. A localized glaze of ice can not be ruled out in this area as well. Short Term - 6am Saturday Morning Through Saturday Night Conditions generally improve through the day on Saturday, with upslope showers expected in the mountains. These showers gradually wind down through the day and skies clear up everywhere as higher pressure moves in. Highs look to be on the warmer side, with upper 40s in the mountains and lower 60s near the coast. Saturday night, partly cloudy skies and light northwesterly winds will allow for chilly low temperatures. It's not likely that locations will completely calm, so radiational cooling Saturday night will likely be inefficient. Lows look to range from lower 20s in the north to mid-30s along the coast. Long Term - Sunday Through Friday Key Message: Near to below normal temps thru the extended. Best chance for precipitation early in the week followed by breezy offshore winds and upslope showers. Impacts: No significant weather impacts anticipated. Some wintry weather expected in the mtns. Forecast Details: Most of the action will occur in the first part of the extended as a seasonably strong trough crosses the eastern CONUS. The bulk of the anomalous conditions will be in the base of the trough...mainly over the Southeast...but a strong upper level jet and left exit region will approach the forecast area Sun/Sunday night. Ensemble already showing a good cold air damming signal...with u- shaped isobar pattern and high pressures branching north of the region. This is a common failure mode for the NBM temps...so I have lowered both max temps and hourly temps Sunday as precipitation moves in with that in mind. It will be a cold rain for most...but some wintry precipitation is likely for the higher terrain. It will start as snow initially...but as the column should dry out eventually this may turn to drizzle/freezing drizzle. Given the uncertainty surrounding surface temps at this range...I have kept precipitation types just rain and snow for now. By Monday night a solid cold front will be working thru the region. Strong Cold Air Advection will help with mechanical mixing but I would not be surprised if we needed a little sunshine Tuesday to help mix the front completely thru. Cold Air Advection will continue into at least Tuesday night...so I anticipate gusty winds for around 24 hrs. That will also start a period of below normal weather...where temps largely stay in the 40s for most locations. With continued offshore winds thru the remainder of the week...upslope cloud cover and rain/snow showers will also linger in the mtns. Marine Short Term Seas increase to SCA (Small Craft Advisory) levels tonight, with southerly picks picking up to around 30kts. Seas will peak early Saturday morning at 3-7ft. By Saturday morning, marine conditions improve with diminishing seas and westerly winds through the day. Seas return to below SCA (Small Craft Advisory) levels by Saturday evening. Winds and seas continue to calm from then through Sunday morning. Long Term Winds and seas will increase Sunday night as east southeast LLJ lifts over the waters. At this time SCA (Small Craft Advisory) conditions appear most likely. After a brief break Monday a strong cold front crosses the waters and winds become stronger Tue. Gale force gusts are possible outside the bays with strong SCAs (Small Craft Advisories) likely inside the bays. Generally gusty offshore flow will continue for much of the rest of the week. Tides / Coastal Flooding Along to offshore winds continue to produce a negative surge and likely will continue to do so through Saturday. While astronomical tides remain high through the weekend, no flooding is anticipated. NOAA Gray/Portland ME Office - Watches - Warnings - Advisories ME...None. NH...None. Marine Small Craft Advisory until 10am EST Saturday for ANZ150>154. |
