The first major blast of cold air will sweep across much of the northeastern United States this weekend and will be accompanied by snow and strong winds in some areas. The same storm set to bring the first heavy snow and blizzard conditions of the season to the northern Plains into Friday will turn eastward this weekend. Cold air wrapping around the storm will slash temperatures by 25-50 degrees Fahrenheit in about 36 hours from the Midwest to the mid-Atlantic.
More than half of the temperature plunge can occur in the matter of a few hours. Temperatures in Pittsburgh, Cleveland, Morgantown, West Virginia, and Buffalo, New York, will plummet from the 60s and 70s on Friday to the upper 20s and lower 30s during Saturday night. Then, temperatures may recover by only 10 degrees or less on Sunday. READ MORE
