The nation's weather

[February 21, 2011]  (AP)  The major winter storm that pounded the upper Midwest on Sunday will provide a significant mix of wintry precipitation to areas from the upper Midwest through the northern Ohio Valley into the northern Mid-Atlantic and the Northeast on Presidents Day.

Several inches of snow are expected to blanket the northern regions, while a mix of snow and sleet along with patchy freezing rain develop in the Mid-Atlantic. Generally light to moderate snow and sleet accumulations of 1 to 4 inches are expected throughout most of the lower Great Lakes and Northeast. Additional snow accumulations of 6 to 10 inches will be possible in the heavier snow bands that pass through these regions during the early morning hours. Meanwhile, ice accumulations of up to a tenth of an inch are also expected to accompany this system. The majority of snow associated with this storm will exit the East Coast by the middle of Monday morning.

As this system exits, the Ohio Valley will see another dose of wet weather activity during the latter half of the day. Rain over the area is expected to change into wet snow during the evening before ending.

Temperatures in the northeastern quadrant of the nation will remain near the freezing mark Monday. Areas to the south will warm nicely with daytime highs in the 60s and 70s due to the passing of a warm front.

In the West, a series of disturbances passing over the Rockies will support more snow showers along the Continental Divide. Meanwhile, a low pressure system will trigger light showers in the Pacific Northwest and the coastal areas of northern California as it approaches the West Coast.

Temperatures in the Lower 48 states Sunday ranged from a morning low of minus 11 degrees at Warroad, Minn., to a high of 88 degrees at Laredo, Texas.
