Today will feature cool temps and the chance for a flurry as a weak area of low pressure passes to the north. temps will be in the 10's and 20's across northern New England and the 30's across southern New England.
Above is my thinking on the snow accumulation for Sunday. I expect the bulls eye to be in southern coastal Maine where proximity to the low, high QPF, and high ratios will all align reasonably well to produce heavy snow. I will have another update tonight or tomorrow morning.
