The upper air wind pattern that has set up over North America is not one that lends itself to warm weather in the northeast. Instead we can anticipate wave after wave of cold air as a series of arctic fronts move our way. One came through Wednesday night and another one is expected to arrive here Friday morning. Out ahead of the front a southwest flow should allow for slightly warmer weather Friday with temperatures reaching the low to mid 20s. On Saturday I expect temperatures to top out only in the teens with morning sunshine giving way to increasing clouds. A storm system will be getting organized in the Mississippi Valley and reach the east coast along the Virginia-North Carolina border by Saturday evening. From here the storm will track northeast and head for the Gulf of Maine. The computer models have been very inconsistent in dealing with this storm and after tracking it well to our east yesterday the latest guidance is bringing the system closer to our region. Right now it's looking to be a significant event with over six inches of snowfall and the bulk of that falling on Sunday. By Monday the storm will be long gone with another surge of arctic air in its wake keeping our temperatures well below freezing.
