The snowstorm that hit Denver was expected to continue into the western Plains,” Roth said, with many areas seeing their first proper snow of this winter.
“Blizzard conditions will affect northeast Colorado, northwest Kansas and southwest Nebraska but Denver should escape,” he said.Winds could reach 35 mph, resulting in areas of blowing and drifting snow, the National Weather Service said.
NOAA’s Storm Prediction Center has issued a tornado watch effective until 6 p.m. CST for parts of southeast Nebraska, southern and central Iowa, northern Missouri and northeast Kansas, The Weather Channel reported. That includes Kansas City, Des Moines and Omaha.
Chicago is likely to see thunderstorms and gusty winds but should escape the tornado threat, Roth said, but Kansas City was “not completely out of the woods.”
“Severe thunderstorms and tornadoes can happen any time of the year,” IEMA director James K. Joseph said in a statement, NBC Chicago reported. “We’re keeping an eye on the storm system predicted for Wednesday, and encourage everyone to stay aware and be prepared to seek shelter if a storm warning is issued.”
By late Wednesday, the snow is likely to have spread to St Louis, parts of western Illinois and as far as western Tennessee.
The most severe thunderstorms were likely in northeast Colorado, southeast Nebraska and northwest Kansas. Parts of Iowa could see both thunderstorms and snow, Roth said.
