Milwaukee, WI – Imagine heading west on Interstate 94 for Thanksgiving, traveling from Milwaukee toward Madison when a wall of blowing snow suddenly sweeps across the highway. Within moments, semitrailers disappear into the whiteout, brake lights become difficult to see and a routine holiday drive turns dangerous. It's the kind of sudden winter weather Wisconsin motorists should prepare for as Thanksgiving approaches Thursday, Nov. 26.
According to the National Weather Service NWS , these intense bursts of snowfall, officially called snow squalls and sometimes described as "micro blizzards," can produce gusty winds, near zero visibility and rapidly deteriorating road conditions.
Unlike prolonged winter storms, snow squalls can develop quickly, leaving motorists little time to react.
Wisconsin Highways Where Sudden Whiteouts Are a Concern Interstate 94, connecting Milwaukee, Madison and Eau Claire, is a major Thanksgiving travel corridor where sudden winter weather can create hazardous driving conditions.
Interstate 90 through Janesville, Madison and La Crosse, Interstate 43 between Milwaukee and Green Bay, and Interstate 41 through Fond du Lac, Oshkosh and Appleton also face winter driving risks.
U.S. Highway 51 near Wausau and Interstate 39 through central Wisconsin are additional routes where heavy snowfall and blowing snow can threaten motorists.
Drivers traveling through Milwaukee, Dane, Waukesha, Brown, Marathon and Eau Claire counties should monitor changing forecasts, particularly when snow showers and gusty winds are possible.
Exposed highways across central and western Wisconsin can experience blowing snow, while areas near Lake Superior and Lake Michigan face additional lake effect snow hazards.
Lake effect snow bands are not necessarily snow squalls, but both can sharply reduce visibility.
What Happens When a Snow Squall Warning Is Issued? The NWS issues Snow Squall Warnings when dangerous snow squalls are occurring or imminent.
Warnings typically last 30 to 60 minutes and may trigger Wireless Emergency Alerts on compatible mobile phones.
Sudden whiteouts at interstate speeds can increase the risk of multivehicle crashes, particularly when motorists brake abruptly or follow too closely.
What Thanksgiving Travelers Should Do If a Snow Squall Warning is issued, the safest option is to delay travel until conditions improve .
Drivers already traveling should gradually reduce speed, increase following distance, activate low beam headlights and avoid sudden braking.
If visibility deteriorates, safely exit the highway when possible rather than stopping in an active travel lane.
Before departing, motorists should check 511 Wisconsin for highway conditions and NWS Milwaukee/Sullivan , NWS Green Bay or NWS La Crosse for official forecasts and warnings covering different portions of Wisconsin.
This is a Thanksgiving travel preparedness reminder, not a prediction that snow squalls will strike Wisconsin during the holiday. Recognizing how quickly dangerous winter conditions can develop could help motorists make safer travel decisions as Thanksgiving approaches.
