Area Forecast Discussion National Weather Service Gray ME 655am EST Sat Nov 9 2024 Synopsis Gusty northwesterly winds will continue this morning, before gradually easing through the afternoon as high pressure builds into the region. High pressure and seasonable temperatures persist through Sunday. Scattered showers return early next week with a broad trough of low pressure before high pressure and mainly dry conditions return by the middle of next week along with near seasonable temperatures. Near Term - Until 6pm This Evening 6:50am No notable changes with this update, mostly just fitting to trends so far this morning. Gusty conditions persist this morning, and then a gradual easing of winds is expected through the afternoon hours. Upslope snow shower activity has retreated to primarily the northwestern slopes of the Whites, and will continue to diminish in coverage through early afternoon. Previous... Gusty conditions continue this morning, along with some scattered upslope snow showers through the higher terrain. Gusts likely peak in the first few hours after sunrise this morning, and then gradually ease through the afternoon as high pressure builds into New England. The upslope snow shower activity will also dissipate as the high moves in. Temps look to be just below normal today, with highs ranging from uppers 30s across the north, to near 50 along the coastline. Mainly sunny skies are expected south of the mountains, with decreasing cloud cover across northern areas through the afternoon hours. Short Term - 6pm This Evening Through 6pm Sunday A seasonably cool night looks to be in store tonight. Winds mostly die off by the late evening as the high pressure center continues to build into the area, with the ridge axis crossing through tomorrow morning. This brings excellent radiational cooling conditions, allowing sheltered valleys to cool into the mid teens, while most other locations dip into low to mid 20s. The cooler conditions don't last long through. The high moves offshore during the daytime tomorrow, bringing a moderating southwesterly return flow. Temps rebound into the mid 50s across most of the coastal plain, with highs near 50 across northern areas. The day starts off sunny, but high clouds begin to filter in during the daytime ahead of an approaching cold front from the west. A stray shower can't be ruled out across western areas before the evening tomorrow, but most locations won't see the shower activity arrive until tomorrow evening and night. Long Term - Sunday Night Through Friday Sub-tropical ridging over the Gulf of Mexico at 500 MB hold in the place through the extended forecast, which will make it difficult for deep trough to develop over the E half of the CONUS, and also keep the coldest air confined mostly poleward of the Arctic Circle. Flow will tend to more zonal over the CWA, with a few less amplified troughs and ridges moving though850 temps mostly hover in in the 0 to + 5C range, bit a brief periods below and above that are expecting in the trough and ridges, making for a somewhat changeable temps next week, bit overall temps mostly near to above normal at the sfc. Sunday should start sunny, with some clouds moving in late in the day and highs in the 50s as surface high passes to our S. A compact closed low crosses the great Lakes Sunday and moves into SW QC by Monday morning. A weak wave rotating around the SE side of that system will produce some showers Sunday into early Monday. Previous model runs showed this system tracking more W-E through the CWA, but 12Z models tend to the core 500 MB to our NW, so this will limit the Quantitative Precipitation Forecast and allow for faster clearing outside the mtns on Monday. Lows Sunday night will be in the evening, and range from the low to mid 30s in the mtns to the low 40s in the S, but temps will rise a bit after midnight, as S flow picks up. We break into the warm sector on Monday behind the warm front, with at least partly sunny skies S and E of the mtns and highs pushing into the 60-65 range in the S, but still only the 50s in the mtns. The surface cold front holds off until Monday evening, and could produce some mtns showers, which may end as snow in the mtns, especially on higher terrain, but it will stray dry to the S. Mins fall into the low to mid 30s in the N to low 40s in the S. Narrow but high amplitude ridge moves in for Tue/Wed. With dry and sunny conds and temps generally running near normal. The next system moves in toward the end of the next week, but looks like it will not produce much in the way of precip, although it will usher in some potentially colder air. Marine Short Term Northwesterly gales across the outer waters and Penobscot Bay begin to ease late this morning, with SCA (Small Craft Advisory) conditions continuing through the afternoon. Fair conditions return this evening and overnight as high pressure crosses the waters. Southwesterly winds begin to freshen ahead of a cold front tomorrow, with some gusts to near 25kt possible tomorrow afternoon across the outer waters. Long Term SCA (Small Craft Advisory) may be needed Monday into Monday night, in SW flow ahead of cols front, which will shift to NW on Tuesday.
