NORMAN, Okla. (AP) — Forecasters say a mixture of bad weather including heavy snow and tornadoes is expected as a strong storm system plows toward the central U.S. from the Rocky Mountains. A blizzard warning has been issued for Tuesday night and Wednesday in the Great Plains east of Denver, while tornadoes and high winds could rake parts of the Midwest on Wednesday.

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

The Storm Prediction Center says an area from Nebraska to Illinois might face high winds, large hail and tornadoes Wednesday.
