National Weather Service officials were expecting two to four inches of snow accumulations in portions of central, north central, northeast Illinois and northwest Indiana beginning to fall Tuesday evening.
A Winter Weather Advisory was in effect from 6 p.m. Tuesday to 12 p.m. Wednesday warning of possible hazardous conditions that may impact morning commutes until snowfall diminishes and temperatures rise above freezing, officials said.
A new storm system over the South was expected to bring heavy snow to portions of the Southern High Plains, Mid- Mississippi Valley, Ohio Valley, Great Lakes and Northeast through midweek. Officials warned strong to severe thunderstorms and a threat of flash flooding can be expected across portions of the Gulf Coast states and Lower Mississippi Valley Tuesday through early Wednesday.
An Alberta Clipper dropping through the Northern High Plains, Upper Mississippi Valley and into the Upper Great Lakes region will usher in areas of light snow. Temperatures will generally be below average across most of the Intermountain West and the southern Plains, with above normal temperatures for much of the eastern third of the nation going through midweek, weather officials said.
Snow was expected in central to northeast Illinois and northwest Indiana where slippery road conditions may arise, officials said.
