Weather Underground Forecast for Friday, February 01, 2013.
Cold air will continue spreading across the Central and Eastern U.S., while scattered snow showers will persist for the Great Lakes on Friday. A low pressure system moves further away from the East Coast and into eastern Canada. At the same time, high pressure continues building in behind this system, and spreads cold Canadian air into the center of the nation. This will push chilly conditions over the Eastern Valleys, with bitterly cold temperatures persisting for the Northern Plains and Upper Midwest. Expect daytime highs to range from 10 to 20 degrees below seasonable. The Northern Plains and Upper Midwest will see another day with highs barely reaching above zero, but strong and gusty winds will allow for wind chill values to range from 20 to 30 degrees below zero in the early morning hours. A cold front will develop over the Tennessee Valley and advance southeastward over the Southeast and Mid-Atlantic states. This may trigger a few more snow, freezing rain, and rain showers over the Southern Appalachians and Mid-Atlantic states before it moves offshore and into the Atlantic.
Meanwhile, out West, disturbances continue moving over the Intermountain West and northern Rockies, triggering a few more scattered snow showers throughout the day. Snowfall accumulation will be light, ranging from 1 to 3 inches from Idaho through Montana and Wyoming.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of -22 degrees at Crosby, N.D. to a high of 78 degrees at Marathon, Fla.
