NH1 First Alert Weather: Drying Out, Temps Remain Mild
NH1 Chief Meteorologist
Surface low slow to move east across the area on Wednesday, with lingering light rain and drizzle across the eastern part of the state. Elsewhere there should be improving conditions with decreasing clouds this afternoon with some breaking sun inland and temperatures again in the 50s. Although we will be in the cold sector of this system, there is not much in the way of cold air with it. As the upper trough moves over the area, there could be a few widely scattered showers developing in the afternoon across the north country.
COASTAL FLOOD ADVISORY
High astronomical tides continue today for the midday high tide. Minor coastal flooding is likely in vulnerable locations along the shoreline. Minor splashover and some beach erosion is possible, but without a big storm off the coast, the seas are calmer. This King Tide is a bit tamer compared to October's.
Low level moisture remains relatively high through Wednesday night, so expect temperatures to remain mostly above freezing. Skies will become partly cloudy with drier air. A building upper ridge will be shifting east Thursday through early Saturday. This will make for 3 sunny days in the 50's to near 60. Temperatures will average above normal into the weekend.
However, we will be watching a potent upstream trough over the central United States will begin to dig in on Saturday before closing off over the mid Atlantic region for Sunday. Showers will spread into New England Sunday with a potent low crossing the region. As the lows pulls away into Canada, showers will be changing to snow showers for late Sunday into Sunday night with developing cold NW winds. NW flow will be upsloping across our Northwest mountains allowing for an accumulating snow fall potential into Monday for the higher elevations and their northern slopes.
The upper low will then pivot northward across New England through early Tuesday before lifting northward directing in much cooler air from Canada to start the week with highs only in the lower 40's. One of our models is hinting at some storm development around Thanksgiving into that Friday. Temps could be cold enough for some snow track dependent. Way to early to have any real confidence in these models that far out. But we ill watch to see if trend continues!
