CHICAGO (CBS) — Patchy freezing drizzle for the early Wednesday morning rush could glaze over the roads.
This is especially likely before 9 a.m.
A Winter Weather Advisory goes into effect from 6 a.m. to noon Wednesday for much of the Chicago area. Freezing drizzle is expected with total ice accumulations of a light glaze to a few hundredths of an inch.
There is also a Dense Fog Advisory for northwest Indiana and Kankakee County until 9 a.m. Visibility will be near zero at times.
After that time, temperatures rise into the middle 30s and the freezing drizzle changes to very light rain sprinkles.
But Thursday brings much colder air.
Our attention then turns to a messy system headed our way for Friday afternoon into Saturday afternoon. The models are not in agreement about the type of precipitation we’ll see. Some scenarios keep us on the warm side with snow in southern Wisconsin (about 6 inches), while others bring accumulating snow to Chicago.
It’s too early to pin down a track, and precipitation type, for our next winter weather maker.
