MINNEAPOLIS (AP) - A powerful snowstorm is burying parts of the upper Midwest in as much as 20 inches of snow.
Authorities have closed roads across five states as heavy winds make for treacherous driving conditions.
The blizzard, which started in the Rocky Mountains, has spread to Nebraska, Iowa, South Dakota, Wisconsin and Minnesota.
The National Weather Service says eastern Minnesota's Oakdale area got 20 inches of snow as of this afternoon. The storm is moving eastward. It's dumped about a foot of snow in northwestern Wisconsin and is expected to drop 20 to 24 inches by tomorrow morning in the Eau Claire area.
The Twin Cities east metro area has received 15 to 20 inches of snow and is expected to see another 1 to 3 inches before the storm tapers off there. The airport has been closed.
The New York Giants are having trouble getting to Minnesota for tomorrow's game against the Vikings. The Giants' charter flight was forced to land in Kansas City where the team will spend the night. They'll fly to Minneapolis in the morning.
