Winter storm to bring widespread travel hazards to Midwest, NWS says
Much of the Midwest is expected to see a significant winter storm beginning Tuesday night and continuing through Thursday morning.
The National Weather Service (NWS) warns that this system can bring dangerous wind chills and blowing snow, producing dangerous travel conditions across the Upper Midwest.
Temperatures will be 10°F. to 25°F. below average over the Northern Plains/High Plains, according to the NWS.
“A strong cold front extending from the Great Lakes to the Southern High Plains will move eastward to the Northeast Coast to the Central Gulf Coast by Thursday evening. The front will produce significant winter weather that is expected to impact much of the central U.S. beginning Tuesday night, bringing a variety of winter weather hazards, including heavy snow, sleet, and freezing rain,” NWS forecasters stated Tuesday.
Several rounds of winter weather are expected to last through Thursday for the Midwest before shifting to the interior Northeast, according to the NWS.
Heavy snow is expected over the Southern Rockies and from the Southern/Central Plains and the Middle Mississippi Valley through the Great Lakes/Ohio Valley and Interior Northeast, according to the NWS’s Tuesday forecast.
“A corridor of heavy ice (rain/freezing rain) accumulation is likely from Texas through the Ohio River Valley. Winter Storm Watches and Warnings are in effect for much of the areas to be affected by heavy snow and ice. In addition, the combination of snow and ice may cause hazardous road conditions,” the NWS forecasters stated.
Along with snow and/or ice, below-freezing temperatures for a couple of days after the wintry precipitation ends can be expected for the impacted areas.
“The cold temperatures will be due to the emergence of arctic high pressure in the front’s wake, which will descend over the Plains on Wednesday. This high pressure will send very frigid air down the Plains between Wednesday and Friday. As a result, high temperatures for many places across the Plains will be 15˚F. to 25˚F. below average during this period. Therefore, the public is encouraged to plan now for prolonged hazardous winter weather conditions and disrupted travel,” NWS forecasters stated Tuesday.
