Overview
Let the games begin…it is now snowing in State College and Altoona in upstate Pennsylvania and the look to winter is suddenly upon us in the Mid-Atlantic region.  Low pressure today will head towards the Mid-Atlantic coastline and a cold rain in the I-95 corridor may actually end as a mix of sleet or snow tonight to the north and west of the big cities.  A powerful cold front will arrive with gusty winds on Thursday night and usher in an Arctic blast for Friday and Saturday with the lowest temperatures of the season so far.  An overall upper-atmosphere pattern with "high-latitude blocking" is looking increasingly likely for later this month and that could result in more cold air outbreaks for the Mid-Atlantic region by the time Thanksgiving week rolls around.

Snow/sleet possibility later today/tonight
Low pressure has formed along a stalled out frontal boundary zone over the Tennessee Valley and it is heading towards the Mid-Atlantic coastline.
