Heavy Great Lakes Snow through Friday; Extreme Cold and Potential for Major Winter Storm Late Week into this Weekend

Multiple clipper systems will bring cold temperatures and enhance lake-effect snow downwind of the Great Lakes. An arctic blast will bring frigid temperatures accompanied with gusty winds that may lead to dangerous wind chills beginning in the Northern Plains Thursday before expanding to the South and East. An expansive winter storm will start Friday in the Southern Rockies/Plains and Mid-South. Read More >
