| Area Forecast Discussion National Weather Service Gray ME 226pm EST Fri Feb 27 2026 .WHAT HAS CHANGED... Trend continues for warmer temperatures this Saturday. This is to be followed by some light snow and a rapid return to cooler temperatures late this weekend and to begin next week. .KEY MESSAGES... 1. Warmer temperatures in store for Saturday. 2. An area of snow will move across the forecast area Sunday resulting in a quick but light accumulation of snow. 3. Next week harbors a couple chances for precipitation, mainly in the Tuesday/Tuesday night and late week timeframe, as well as a fairly confident signal for a late week warm up. This pattern could result in mixed wintry precipitation for a portion of the area, as well as snowmelt/and some river ice rot during the daytime. KEY MESSAGE 1 DESCRIPTION...A cold front will approach the region Sat and will affect sensible weather in two ways. One will be warm advection and compressional warming ahead of the front will allow temps to climb into the 40s. There may even be a run at 50 degrees for a few locations. Across the interior the southwest flow may also fail to really scour out the low level cold, especially with deep snow cover, and afternoon readings could end up closer to 40. The second factor will be showers along the front. Given the mild temps these may be rain or snow depending on location and time of arrival. And precipitation may be briefly heavy as it moves thru quickly during the afternoon and evening. This will mainly affect the mtns and maybe clip the lower Kennebec River Valley. KEY MESSAGE 2 DESCRIPTION... A trough passing through New England will bring a period of light snow to the forecast area Sunday. Forecast accumulations come out to just around an inch, but will push through the CWA through the day. Morning travel could be slick across much of NH, with the afternoon focus on ME. Overall lift is limited despite a deepening DGZ. Thus would expect increased snow rates to be brief within the event. NBM v5 probabilities of exceeding 2" are also below 20% for the area through Sunday evening. The passing trough will welcome back much cooler temperatures overnight, with lows plummeting back into the single digits above and below zero. KEY MESSAGE 3 DESCRIPTION... Three topics for next week featuring two main precipitation windows and then a warming temperature trend. The two precipitation makers still have a wide range of outcomes, with even the warming trend including an asterisk with it. Focusing first on the early to mid week system, it follows on the heels of exiting high pressure across the eastern CONUS. Highs don't get as much glory as their counterparts, but the increasing chance of a 1040mb MSLP high through the Northeast represents a strong high for this time of year. It will be responsible for a cool down Sunday night through Monday night (highs in the teens and 20s, lows in the single digits above and below zero), and also swift return, warming, flow into the middle of the week. Quantitative Precipitation Forecast presentation of low pressure flatly exiting the Great Lakes and Ohio Valley is represented across guidance, but some hints of phasing and different transit speed leaves a lot on the table for potential totals and temperature profiles. Given the chance for above freezing temperature layers in this system, mixed precipitation may be possible for a portion of the area. For now this could materialize across the southern third of the forecast area. Into late week, another system looks possible, along with a likely warmup. This will again likely feature strong high pressure, instead positioned to the north and west. Will need to watch how much dry air could be forced into northern New England for late week that could temper Quantitative Precipitation Forecast expectations. This high will also play a role in how far north the second system pushes, thus exactly how warm it gets late week will also depend on this weather system. For now, highs in the 40s Wed-Thurs and maybe Friday will be possible. As with the early week system, a chance for mixed precipitation also exists with the next round. As ensembles struggle represent CAD, would need rely on broad pattern recognition should overnight temps in the teens and 20s lock in across the interior. Marine Southwest winds will increase tonight ahead of an approaching cold front. Warm advection over cold ocean waters will struggle to mix down the strongest wind gusts, but a period of marginal SCA (Small Craft Advisory) gusts is expected Sat. SCA (Small Craft Advisory) remain in effect for all waters. Winds and seas will begin to diminish Sat night. NOAA Gray/Portland ME Office - Watches - Warnings - Advisories ME...None. NH...None. Marine Small Craft Advisory from 9pm this evening to 10pm EST Saturday for ANZ150-152-154. Small Craft Advisory from 11pm this evening to 4pm EST Saturday for ANZ151-153. |
