| Area Forecast Discussion National Weather Service Gray ME 1007am EST Tuesday Jan 27 2026 .WHAT HAS CHANGED... Quick update to expire the Freezing Spray Advisory on time. No other major changes were needed for this update. .KEY MESSAGES... 1. Well below normal temperatures continue thru the second half of the week. While apparent temperatures will get below zero, it does not appear it will be cold enough for any headlines. 2. Cold but mainly dry weather continues through the rest of the the work week with the potential for a bit of a warmup over the weekend. Signals for another coastal storm are appearing for this weekend but model spread continues to be rather wide with low confidence in the forecast arising due to that. KEY MESSAGE 1 DESCRIPTION... NWP (Numerical Weather Prediction) continues strong agreement for below normal temps for the foreseeable future. Generally looking at 5 to 10 degrees below normal, which is well below normal but unlikely to set any records. There will also be breezy northwest winds off and on for much of the week. This will drop wind chills overnight below zero, as cold as 10 or 15 below in the mtns. During the day those values may climb into the single digits or low teens, but it will certainly feel very cold out there. Occasional reinforcing cold fronts will arrive with shortwave trough. pinwheeling around the larger upper low, and we do have our eye on one for this afternoon. As it swings thru snow showers are likely to become more widespread. I will maintain some mention of snow showers in the afternoon forecast despite the NBM have low or no Probability of Precipitation inland. Bufkit soundings have the snow growth zone near saturated and in the very low levels, so any lift in that layer should produce some flakes. Unlike this past evening where the upper levels were saturated as well, they will be drier this afternoon. So any accumulation will be more like a dusting. KEY MESSAGE 2 DESCRIPTION... Cold weather continues for the rest of the work week but not brutally cold. There may be snow showers from time to time mid to late week under mean troughing but impacts will be minimal. We continue to monitor the potential for a coastal storm for this weekend. However, ensemble spread is much too wide at this juncture to have much confidence in any significant weather impacts here. A large portion of the guidance currently relegates this storm to the southeast and mid atlantic coasts with minimal impacts here. However, there is still plenty of time for this to change and we will obviously continue to monitor. Marine Low pressure continues to pull away from the Gulf of Maine this morning with steady offshore flow through today. While winds diminish through the day SCA (Small Craft Advisory) conditions will be in place through the first part of tonight with elevated seas. As the core of the cold air aloft moves overhead this afternoon, snow showers will become more numerous over the waters. Local visibility below 1 mile is possible. Long term...Sub-SCA (Small Craft Advisory) conditions are expected into Saturday but a period of SCA (Small Craft Advisory) conditions will be possible Thursday night. Otherwise, higher wind gusts and seas may not return until Sunday and will be dependent on the track of a coastal low pressure system. NOAA Gray/Portland ME Office - Watches - Warnings - Advisories ME...None. NH...None. Marine Small Craft Advisory until 10pm EST this evening for ANZ150>152-154. |
