Discussion
A high impact weather event is underway for much of the eastern US with bands of accumulating snow to be followed by extreme cold and dangerous sub-zero wind chills. A powerful storm over the western Atlantic Ocean is intensifying rapidly on its way to the east of Maine by early tonight. This storm will reach hurricane-like strength by tonight with its central pressure bottoming out at category 3 (major) hurricane levels. Extremely cold air will pour into the eastern US on the heels of this ocean storm and winds will strengthen significantly for tonight, tomorrow and Saturday. The combination of wind gusts past 40 mph and the extremely cold temperatures will generate dangerous sub-zero wind chill values for an extended period of time from tonight to Saturday night. After that, some moderation in temperatures should arrive early next week, but that temporary “warm up” may be accompanied by some wintry precipitation.
