Weather Underground Forecast for Saturday, February 02, 2013.

The East Coast will start to warm up on Saturday, while snow showers continue for the Great Lakes and Ohio River Valley. A ridge of high pressure advances eastward and off the East Coast on Saturday as a trough of low pressure moves into the Great Lakes and Midwest. This will bring scattered snow showers to the North-Central U.S. with 1 to 3 inches of new snow. The system will create a cold front that stretches southward, producing a few rain showers over the Eastern Valleys. Flow around this trough of low pressure will pull warmer air in from the south. Thus, this will allow for warmer temperatures to spread across the Eastern Valleys and East Coast. The Tennessee Valley will return to the upper 40s, while the Mid-Atlantis states will see highs returning to the upper 30s to lower 40s. Behind this system to the west, another weaker trough of low pressure moves into the Northern Plains and Upper Midwest from central Canada. This will bring light and scattered snow showers to the Dakotas and Minnesota. Further west, a ridge of high pressure maintains dry and mostly sunny conditions for the West Coast and Western states as it pushes moisture away to the north.

Temperatures in the Lower 48 states Friday have ranged from a morning low of -34 degrees at Park Rapids, Minn. to a high of 79 degrees at Falfurrias, Texas
