Winter Storm Ivy will spread snow and freezing rain from the South Plains to the Great Lakes, and some snow may develop across West Texas. Heaviest wintry accumulations will be from the Midwest to the Great Lakes. Ivy may produce heavy rain that could cause flooding and flash flooding, and severe weather potential. A second system on the tails of Ivy may cause a series of storms that will bring heavy rain and gusty winds to much of the West.
