Weather Underground Forecast for Friday, December 04, 2009.

Cool air continues to pour in over the Central and Eastern US on Friday. A low pressure system will continue spinning in eastern Canada and a trough will extend over most of the Eastern half of the country. This will bring another day of scattered flurries to the Northern Plains and Upper Midwest with snowfall less than an inch. Meanwhile, this system will pull enough cold air and moisture across the Plains and allow for another cold night over the Southern Plains. Frost and freeze advisories will remain in effect Friday night, and daytime high temperatures will be at least 10 degrees cooler than seasonable. Overnight flurries will linger throughout the day, with snowfall accumulation up to a half of an inch over parts of Texas and Oklahoma.

Meanwhile, high pressure will start to build in from the Rockies and allow for cool air to persist while starting to dry out the region. The Northern Rockies will see mostly sunny skies with bitterly cold temperatures. Parts of northern Wyoming will see wind chills as low as -20 degrees on Friday.

In the Northeast and New England, flow front the northwest will pick up moisture from the Great Lakes and allow for a few scattered flurries over New York. The region will remain in the 40s with overcast skies.

Out West, high pressure continues to build over the West Coast. A low pressure system and cold front will approach from the Pacific Ocean and push a few clouds over the Pacific Northwest. The north will see highs in the upper 40s, while most of California will remain in the 60s and 70s.
