DAYS 1-5 (OCTOBER 29 – NOVEMBER 2)
Discussion…
Today, you get spared a long discussion and instead just get this quick summary, because there is not really any change to my thoughts on this forecast. Low pressure passes south of the region tonight and Friday, starting as rain, which will be somewhat beneficial but not as much as some model forecasts have been – another few chips taken out of the drought. Colder air flips the rain to snow first in higher elevations north and west of Boston then eventually toward the city as the precipitation shield gets ready to depart during Friday. Minor snowfall accumulation on the order of a coating to 2 inches take place, greatest in higher elevations well north and west of Boston before things come to an end, and while most of any snow melts away later Friday, even with cold air moving in, some wet ground and puddles will remain and that sets up a good chance for ice patches Friday night as temperatures fall below freezing pretty much regionwide. No changes to the weekend with a chilly but tranquil Halloween, a full moon rising in the evening before clouds arrive, then a milder, breezy Sunday with a rain shower risk as a warm front passes and a cold front approaches. This cold front will bring a fresh shot of cold air by Monday.
