The Weather First Team is expecting heavy, wet snow on Wednesday morning and because of that, a Storm Alert has been issued. Winter Storm Warnings have been issued for areas along and south of I-44 in Missouri and along and east of I-55 in Illinois for Tuesday evening into Wednesday. This does include the metro St. Louis area.
A heavy, wet snow is expected to fall through the morning on Wednesday. Temperatures will be around freezing while the heaviest snow falls and this will likely create slushy snow on area roadways.
Accumulation is likely with the heaviest amounts likely from the Ozarks into southeast Missouri and parts of southwest Illinois, where four to eight inches of snow is likely. A few areas may see more than eight inches of snow, but since it is a wet snow, it will compact.
Farther north and west, snowfall amounts will likely range from one to four inches. Most of the immediate St. Louis metro will likely see a solid three to five inches of snow.
