The storm will impact about 200,000 square miles with snowfall rates of 1 to 2 inches per hour in some areas. And more winter weather arrives midweek.

Winter storm warnings are in place for 10 states from the National Weather Service (NWS) on Thursday, with up to 30 inches of snowfall expected in some parts of the U.S. Freezing temperatures may present health risks, especially for vulnerable groups such as infants and older adults.
