Area Forecast Discussion National Weather Service Gray ME 359am EDT Thu Mar 27 2025 Synopsis High pressure passes south of the region today, with unsettled conditions returning this weekend. Widespread precipitation is likely this weekend into early next week as low pressure moves out of the Great Lakes, potentially bringing a variety of precipitation types and messy travel to the region. Conditions trend drier for the middle of next week. Near Term - Until 6pm This Evening Upper trough tilts negative today with last push of clouds set to push across the CWA (County Warning Area) through early afternoon. More low level dry air will limit showers to only the mountains as this swings through. Otherwise, winds pick up as daytime mixing increases, but will slacken into the evening. Surface temps remain very similar to the previous two days with highs in the mid to upper 40s. Short Term - 6pm This Evening Through 6pm Friday Mostly clear skies into this evening will cloud over as the night progresses. A cold front will pass overhead, also bringing the chance for light snow showers. Moisture depth supporting precipitation is fleeting, and may be hard to satisfy outside of the mountains overnight. These will be wrapped up by Friday morning. It will be dry but breezy behind the exiting front Friday, with gusts generally 20 to 25 mph. Upper/mid jet will be pushing into northern ME as the day goes on, and this northward extent will play a role in setting up conditions for this weekend, namely surface temperature trends. With a flatter continuation of the jet, the low levels won't be as willing to push north with warm air. Long Term - Friday Night Through Wednesday Wednesday Evening update: Weekend system(s) continue to look impactful to travel. Of note will be mod to heavy snowfall rates on the northern periphery (for now forecast across northern NH and far western ME) Friday night and Saturday morning. This was also echoed in collaborations with WPC where this area is situated below the right entrance region of upper jet. Guidance continues to show fairly robust CAD to keep surface temps cool. This will have implications further south into central NH and southern ME where a mix of freezing rain and sleet appear likely. Plenty of refinements to be made in the next few forecast periods, but bottom line is a corridor of accumulating winter precipitation to affect travel this weekend. Previously: The main takeaway for this weekend into early next week is an extended period of messy weather with difficult travel. There is increasing confidence to see all varieties of precipitation types across the area while confidence remains low on amounts and where each type(s) will fall. The primary culprit is a pseudo-stationary boundary just to our south with multiple waves of low pressure riding along it creating periods of wintry precipitation with a couple of breaks or lulls possible. The uncertainty is mainly due to the meandering nature of the front and how much of an influence the high pressure to the north will be in keeping the front farther south or allow it to lift farther north. Latest guidance for Friday night into the first part of Saturday favors mostly snow for northern areas while more of a mix is possible farther to south, including sleet and freezing rain. The rest of the weekend is more uncertain as it depends on how far north the front gets or how far south it stays, but there does seem to be a trend for the warm nose aloft to push north, especially going into Sunday, which would bring chances of mixed precipitation farther north as well. Things will likely change between now and then, so for now the forecast has mention of all precipitation types, and types/amounts will be refined over the coming days. Again, there could even be breaks or periods of drizzle if the influence of the high pressure trends farther south. Global models are in good agreement this far out in finally pushing the primary low and cold through the area Monday night or early Tuesday with a drying trend toward the middle of next week as high pressure builds into the region. Marine Short Term Main feature affecting the waters will arrive late tonight/early Fri morning as a cold front. This will cause a period of SCA (Small Craft Advisory) gusts as winds shift SW to W. These gusts will be strongest over the coastal waters, up to 30 kt. Long Term Over the weekend, winds will be primarily out of the east or northeast as a boundary becomes nearly stationary just south of the waters. Periods of SCA (Small Craft Advisory) conditions are possible. For early next week, winds may stay east/northeast or could be more southerly if the boundary lifts north and the primarily low from the Great Lakes takes a more northerly track. Either way, SCA (Small Craft Advisory) conditions and maybe even a period of gales are possible over the waters. High pressure looks to build across New England toward the middle of next week. NOAA Gray/Portland ME Office - Watches - Warnings - Advisories ME...None. NH...None. Marine Small Craft Advisory from 5am to 2pm EDT Friday for ANZ150- 152-154. |
