Weather synopsis: Sunday November 28


12:20pm a dome of High Pressure is dominating the weather across the east producing generally fair weather from Maine to Florida. Temperatures are forecast to moderate today and tomorrow, this should melt most of the snow from this weekend's Lake Effect. Reports of generally 2 to 4 inches of snow came in from Buffalo with higher amounts south of the city on the order of 5 inches to well over 1 foot. There will be a lull in the weather through Monday ahead of the next storm system, this next low pressure system will affect enter the Northeast on Tuesday bringing heavy rain and possible severe thunderstorms. By Wednesday, a cold air mass will rush in behind this system and will likely change the rain to snow before ending on Wednesday evening from Buffalo to Long Island. The cyclonic flow (counter clock wise) around this low pressure system will orient the winds over the Great Lakes and will likely initiate another round of Lake Effect Snow along the snow belt Wednesday through Thursday. Snowfall accumulations could be heavy in localized areas downwind of the lakes. Looking ahead in to the first weekend of December and beyond, forecast models are hinting towards the development of a storm system that could affect a good portion of the Northeast with heavy wind driven snow; it is still too early to say whether or not this will transpire, I will continue to monitor this situation as the time frame approaches.
