Winter Weather Alerts: Northern U.S. Faces Hazardous Conditions and Storm Warnings

This Thanksgiving weekend, travelers should brace for heavy snow, rain, and cold temperatures. Winter storm warnings stretch from Montana to New York, affecting many states, especially Iowa and Illinois. Accumulations of six inches to a foot of snow are expected in parts of west-central Illinois from Friday night through Saturday night.

Meteorologists say conditions may not qualify for blizzard warnings just yet, which typically require winds over 35 mph and visibility drops below a quarter mile for over three hours. However, there has already been significant snowfall in parts of the northern Plains and Great Lakes. Areas around Lake Superior could receive more than a foot of snow by the end of the storm, particularly in Michigan’s northern Lower Peninsula and across central New York.

For those traveling in the interior Northeast, snow squalls can lead to sudden heavy snowfall and dangerous whiteout conditions on the roads. Meanwhile, the Pacific Northwest and Rockies will see a mix of snow and rain. As the storm moves on, the Rockies and northern Plains will finally get a break by Saturday, although the Midwest will still be affected.

To the south, strong storms may bring heavy rainfall and potential flash flooding in the western Gulf Coast on Saturday. Temperatures will also be well below average across the eastern and central U.S., with highs only reaching the 20s and 30s in the Midwest and slightly warmer in the Southeast.

On Thanksgiving Day, snowy weather led to several vehicle accidents in western Michigan, highlighting the dangers of holiday travel during such conditions. According to the National Highway Traffic Safety Administration, winter weather can increase the risk of accidents by as much as 27%, making it vital for drivers to be cautious.

The storm’s impact extends beyond road safety. With millions traveling for the holiday, airports are also reporting delays. Even as many try to enjoy the festive season, inclement weather can lead to frustrating travel experiences. Historically, weather-related travel issues spike during the holidays, as noted by the American Automobile Association, which reported that holiday travel increased by 15% over the past decade.
