The nation's weather

[January 15, 2009] (AP) The eastern half of the nation was in a deep freeze, with snow, blasts of icy air and temperatures stuck far below freezing. The Pacific Coast, on the other hand, was enjoying unseasonably mild weather.

Strong northwest winds will pour cold, arctic air into the northern and central Plains, bringing temperatures down to well below zero. These blustery winds will make conditions feel much colder than actual temperature readings and will cause wind chills to range from 15 to 30 below zero.

Wind chill warnings extend across the mid- to upper- Mississippi Valley and across the Great Lakes as arctic air surges across the Midwest.

Lake-effect snow showers were forecast across the Great Lakes. Snow showers will be accompanied by 10 to 20 mph winds and up to 30 mph wind gusts. Strong winds will trigger periods of blowing snow and limited visibility with low wind chills.

To the east, a winter storm system will produce light to moderate snowfall across the northern Mid-Atlantic region as it treks toward the East Coast.

The West, meanwhile, will remain under fair weather conditions on Thursday due to a lingering high pressure system. Southern California was to be in the 80s.

Temperatures in the Lower 48 states on Wednesday ranged from a low of minus 42 degrees at International Falls, Minn., to a high of 89 degrees at San Fernando, Calif.
