| Area Forecast Discussion National Weather Service Gray ME 739pm EDT Wednesday Oct 29 2025 Synopsis Dry weather prevails tonight into Thursday with high pressure centered north of New England. Low pressure near the Mid Atlantic on Thursday morning will cross the area Thursday night into Friday. This system will bring a widespread soaking rainfall with a period of gusty west winds in its wake Friday night and Saturday. Troughing lingers over the Northeast into next week for an unsettled weather pattern. Near Term - Through Thursday 745pm Nighttime microphysics satellite imagery shows a ribbon of cirrus streaming from south to north across portions of north-central NH and into western ME. Further to the south, there is a lower level deck of clouds but satellite trends over the last few hours show much of this retreating to south of our area. The dry airmass is allowing for quick cooling and therefore lowered forecast lows, especially in the normally colder spots. Otherwise, the forecast remains on track. Previously... High pressure centered over Quebec will retreat to the north tonight as an area of low pressure over Tennessee tracks ENE towards the Mid Atlantic. Latest satellite imagery shows mostly clear skies across the northern two thirds of the area with mostly cloudy skies across southern NH into coastal Maine. Clouds gradually advance northward towards Thursday morning while much of the area will experience some radiational cooling. This will bring lows into the 20s across the north and the mid to low 30s across the south. Short Term - Thursday Night Low pressure over the Mid Atlantic will track across the interior Northeast through Thursday evening with ensembles and some deterministic solutions suggesting a secondary low will develop near the coast Thursday night. Clouds will increase Thursday morning with chances for showers increasing SW to NE during the afternoon. It will be cool and raw as easterly winds ramp up with highs mainly in the 50s. The bulk of the precipitation will overspread the forecast area Thursday night as an occlusion forms between the interior low and the secondary low near the coast. An axis of moderate to locally heavy rain will sweep across the area during the overnight with Quantitative Precipitation Forecast still a widespread 1 to 2 inches by Friday morning. A strong ESE low level jet of 50+ kts at 2000 feet will also translate across the area after midnight. An inversion beneath this LLJ will inhibit full mixing, but still some gusts to around 30 mph are possible along the coastal plain and much higher wind gusts above 2000 feet. PWATs (Precipitable Waters) will approach 1.25 inches and those will aid in rainfall rates approaching 0.5 inches per hour. However, the ongoing drought conditions and fast moving nature of the system will limit hydro concerns other than some poor drainage ponding of water on roads. Long Term - Friday Through Wednesday By Friday morning, low pressure swings to the north with widespread rain expected through the first half of the day. Rain starts to break apart from south to north Friday afternoon with a drier end of the day likely for the Seacoast and possibly even Portland. Clouds decrease overnight south of the mountains and a pressure gradient sets up over northern New England, allowing for for a tranquil but gusty Saturday. Winds should peak in the late morning hours, with soundings indicating that wind gusts of up to 35mph could mix down to the surface. Winds slowly die down through the remainder of the day, with 20-25mph gusts still likely by Saturday evening. In locations north of the mountains, showery weather likely continues through Saturday morning. By then, breezy westerly winds will allow for some upslope showers to continue the damp, rainy conditions up there. Some snow may mix in, but mostly rain showers are expected outside of the higher elevations. Upslope precipitation gradually dwindles down through the day Saturday as westerly winds slacken. Winds could be gusty up north as well with 30mph gusts likely in the valleys and possibly exceeding 70mph above 3500 feet. Saturday could be a very dangerous day to trek in the White Mountains, as wind chills will also remain below 0F. The pressure gradient loosens Saturday night as a low over the Canadian Maritimes continues to move eastward and away from New England. A brief bout of high pressure takes over the area Sunday and Monday, allowing for a mostly dry couple days with much calmer winds expected outside of higher elevations. The next system arrives Next Tuesday, as a quick moving shortwave is bound to provide measurable precipitation over the area. Marine Short Term NE winds relax tonight while elevated seas will continue SCA (Small Craft Advisory) conditions over the outer waters into Thursday morning. Low pressure approaches from the SW Thursday evening with easterly winds increasing ahead of this system. Easterly winds and building seas will bring SCA (Small Craft Advisory) conditions to all waters Thursday night into Friday. Long Term Gale force southwesterly winds and 8-11ft seas are expected Friday. A Gale Watch is in effect for Friday night and Saturday. Winds will shift to westerlies on Saturday, with seas subsiding to 5-9ft by the end of the day. Winds and seas continue to diminish through the rest of the weekend, with SCA (Small Craft Advisory) conditions ending by Sunday morning. Winds should be coming from the Northwest on Sunday.
