| Area Forecast Discussion National Weather Service Gray ME 146pm EDT Thu Oct 9 2025 Synopsis High pressure crosses the area through Friday with the coldest night of the season thus far expected tonight. Temperatures moderate Saturday under fair skies. A closed low near the Mid Atlantic will migrate northward early next week and will bring a chance for rain Sunday night into Monday along with building winds and seas on the coastal waters. Near Term - Through Tonight High pressure continues to build into New England through the overnight hours, with the high cresting the region early tomorrow morning. With a dry, cool airmass in place, clear skies, and lightening winds, conditions all align for ideal radiational cooling conditions tonight. This yields the coldest night so far this fall in most areas, and a widespread freeze across the interior. A freeze remains possible all the way to the coastline, with frost likely. A freeze warning remains in effect for all areas still in season. Forecast temps range from the low 20s across the northern valleys, to the mid and upper 20s across most of the interior. Low 30s look mostly likely along the coast. MAV guidance continues to look to be the best performer for tonight, but the forecast doesn't go quite as cold as the MAV, which has widespread upper teens to low 20s. Looking around where the high center was in western Quebec this morning, lows looked to bottom out around 23-25 degrees, so this likely serves as a reasonable lower limit for most of the interior valleys for tonight. Short Term - Friday Through Friday Night Temperatures begin to rebound tomorrow as the high shifts east of New England. Under mainly sunny skies highs warm into the mid to upper 50s across the north, with low 60s likely elsewhere. With the high moving offshore, a seabreeze likely develops in the afternoon. Given the cool airmass, temperatures likely drop into the low to mid 50s along the immediate shoreline with the seabreeze as the airmass doesn't have enough time to moderate over the warmer waters before winds turn onshore. Mainly clear skies continue Friday night, but with a southwesterly flow overnight radiational cooling conditions will likely be more confined to the northern valleys. Here, temps likely drop into the mid to upper 20s. Along the coast, upper 30s to low 40s look most likely, with mid 30s in between across the interior. Long Term - Saturday Through Thursday The long term period starts off with fair weather Saturday and into the first portion of Sunday as high pressure gradually retreats. Temperatures both days will be above normal during the daylight hours. Merging low pressure systems to our southwest are nearly unanimously forecast to gradually move northward up the Mid Atlantic coast as one low pressure system Sunday and Monday. What remains uncertain is how far north the low pressure system gets before dumbelling out to sea by Tuesday in association with a southeastward moving upper level low that is finally getting kicked out. This will determine the northward coverage of rainfall as well as intensity. At this moment there is still quite a bit of ensemble spread here as we'll be on the northern fringe of the system. As of this writing we are moderately confident to go with likely Probability of Precipitation across southern and coastal zones, with lesser Probability of Precipitation well inland. Winds could also be an issue as well with the gradient tightening up between the high to our north and low to our south. Easterly gales will be likely on our coastal waters but winds over the land don't look overly concerning at this point, with gusts possibly up to 30 kt on the coast. There will be a long easterly fetch for a few days early next week. Astronomical tides will be on their way down but still high enough that some minor coastal flooding will be possible. Fair weather then returns later Tuesday into Wednesday before another possible cold front moves through. Marine Short Term Winds continue to ease overnight as high pressure builds across the waters. The high then remains in place bringing fair conditions across the waters through Friday night. Long Term High pressure brings fair conditions to the waters through early Sunday. Seas and winds build starting on Sunday as a coastal low moves up the the Eastern Seaboard. SCA (Small Craft Advisory) conditions are possible by late Sunday, with gales possible across the outer waters by Monday. Tides / Coastal Flooding There will be a long easterly fetch for a few days late this weekend and early next week. Astronomical tides will be on their way down but still high enough that some minor coastal flooding will be possible centered around Monday.
