Snow flurries and cold nights are in store for much of the country Friday. Cool air continues to pour in over the Central and Eastern as a low pressure system continues spinning in eastern Canada and a trough extends over most of the Eastern half of the United States. That means another day of scattered flurries for the Northern Plains and Upper Midwest with snowfall less than an inch.

The system will pull cold air and moisture across the Plains to make 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, with wind chills in parts of northern Wyoming as low as -20 degrees.

In the Northeast and New England, moisture flowing from the Great Lakes will fuel a few scattered flurries over New York. The region will remain in the 40s with overcast skies.

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.

Temperatures in the Lower 48 states Thursday ranged from a low of -22 degrees at Stanley, Idaho, to a high of 89 degrees at Pembroke Pines, Fla.
