8 February Long Range
Forecast updated 2:00pm EST - 8 Feb 2011
Deep dip in the upper level jet stream that has kept much of the Eastern half of the country in a deep chill will finally lift as we move into the weekend. The freezing line will move as far north as Michigan, allowing much of the snowpack a chance to melt over the weekend. With the melting, areas of fog will be possible over the midwest as temperatures reach the low 40's.
Current models indicate another small cold snap before even warmer temperatures move in towards the middle of next week.

Ample moisture being drawn in from a surface low will bring heavy rains to the Southeast. Strong absolute vorticity will overcome slight cold air advection allowing for heavy precip to fall. Some rainfall totals could reach 1"-2" by the time the system moves out.
