More than 22 million Americans were under a winter weather warnings or advisories Thursday as a snowstorm that hammered Denver with the biggest two-day January snowfall in more than 30 years slowly pushed eastward.
"Winter storm continues for the Upper Midwest (and) Great Lakes Thursday with heavy, blowing snow leading to dangerous travel conditions," the National Weather Service's Weather Prediction Center said in a statement.
Additional snowfall totals of around 6-12 inches are forecast for portions of the Upper Great Lakes, and locally higher totals over a foot are possible, the statement said. Much of the snowfall is expected to occur over a period of a few hours. Snowfall rates of 1-2 inches per hour and gusty winds could make "travel difficult to impossible."
