A winter storm warning or blizzard warning was in effect for parts of Utah, New Mexico, Colorado, Nebraska and Kansas through Wednesday afternoon and evening in some places. Tornadoes and high winds could rake parts of the Midwest on Wednesday afternoon as well. Sustained winds of 30 to 40 mph were expected, with gust up to 55 or even 60 mph.

The National Weather Service issued tornado watches for most of the day in parts of Nebraska, Kansas, Missouri and Iowa.

Wet, heavy snow fell in Nevada on Tuesday morning, closing schools in Reno and knocking out power to thousands before moving eastward. Northeastern Colorado and western Kansas and Nebraska expected 6 inches of snow and wind gusts up to 60 mph overnight — a combination that can cause white-out conditions.

“November has a history of producing some significant weather events. We will have to keep an eye on things,” said Greg Carbin, warning coordination meteorologist at the Storm Prediction Center.

The Storm Prediction Center cautioned 54 million people to be alert for severe weather.
