CHICAGO (April 18, 2013)--Mother Nature was throwing all she has at Middle America, from snow in the north to tornadoes in the Plains, and enough rain in Chicago to cause a sinkhole that swallowed cars.
National Weather Service watches and warnings were in place across the region Thursday.
As much as a foot of snow is forecast for parts of Minnesota and the Dakotas.
Downpours were causing rivers to burst from their banks in Missouri, Iowa and Illinois.
Tornadoes caused scattered damage in Oklahoma.
Frost warnings were in effect as a cold front pushed out warmer air.
Rain is blamed for a huge sinkhole in Chicago that swallowed three cars and sent one driver to the hospital.
Winds, possibly from a tornado, damaged dozens of homes in Spavinaw, Okla., and caused minor damage near Paris, Mo.
