A frigid winter cold blast has most of the U.S. in an icy grip, as cold air plunging southwards from Canada will bring temperatures 10 - 40 degrees below average to more than 80% of the contiguous U.S. on Friday, Saturday, and Sunday. Riding up the edge of this cold airmass is Winter Storm Cleon, which is spreading a nasty mix of snow, freezing rain, and sleet from Texas to the Ohio Valley. Hardest hit with freezing rain and power outages has been Texas.

A large winter storm, designated as ‘Cleon’ by The Weather Channel, affected most of the U.S. Tuesday through Friday (November 3-6) and was followed by extreme cold in the Rocky Mountain States and Upper Midwest. Record warmth preceded the storm in the Southeast while an unrelated storm brought low-level snow to Oregon and California on Friday. Here is a brief summary of the main events.
