Travelers delayed by snow squall in Lower Michigan

The National Weather Service in Detroit issued a Snow Squall Warning, cautioning drivers of low visibility and slick roads.

Sudden white-out conditions delayed Sunday afternoon drivers heading home from the long Thanksgiving weekend.  An intense snow squall pushed through Lower Michigan toward Detroit.

FOX Weather radar caught the squall line as it organized around 2:05 p.m. EST south of Flint, Michigan and I-69.  The squall marched south through Waterford, Hartland and Macomb around 3:05 p.m.

The National Weather Service (NWS) in Detroit issued a Snow Squall Warning for Oakland, Macomb and Livingston Counties.

Hours earlier, the NWS Storm Prediction Center identified several bands of lake effect snow that were merging together across Lower Michigan into the squall.   

The squall line traveled Southeast at 25 mph and brought heavy and blowing snow with wind gusts up to 30 mph. The NWS warned of "dangerous, life-threatening travel" on I-75, I-94 and I-96 for suburbs Northwest of Detroit.

A driver in Northern Ohio took video as a lake-effect snow squall passed and reduced visibility.

The NWS warning recommended delaying travel until the squall passed, slowing down and turning on headlights. As you can see from this video, a snow squall quickly cuts down visibility and makes roads slippery.

Previous snow squalls led to high-speed crashes and pile-ups on highways.  Check out the video posted by the NWS office in State College, Pennsylvania.
