Regional Weather: Eastern North America

Strong Autumn cold front plows through eastern North America. Rain and showers will spread from east-central North America on Friday to eastern regions on Saturday. As the front pivots east and northeast, dry and cold weather returns to most areas on Sunday, with showers in the Northeast and mid-Atlantic. Temperatures change markedly on either side of the front. Highs will be in the 60s to 80s and lows mostly in the 50s and 60s ahead of the front; temperatures behind will be some 20 degrees colder.

 

OUTLOOK:

Overview: Epidemic spread possible in some areas. Fall temperatures and other factors are asserting themselves to the point where remaining chances of epidemic spread should be limited to areas in the deep South and along the Atlantic coast. Some spread in those regions is possible, more toward the South Friday and Saturday and in the East on Sunday.
