A wintry mix of precipitation has overspread Northern Illinois bringing rain, freezing rain, sleet, and snow to the area.
Most of the area is currently experiencing freezing rain, and 2/10″ of ice can be expected throughout the entire area from this storm. Far northern areas near the Wisconsin state line, including the Rockford area, McHenry County, and Lake County, will see this precipitation change over to snow or snow mixed with freezing rain at times and can expect 4-8″ of snow before the system exits the area. Precipitation should end between 12 pm and 3 pm Wednesday, though areas along and south of the I-80 corridor should see precipitation ending between 9 am and 10 am.
Multiple saltings will be necessarily for this event. While temperatures may rise slightly above freezing, ground temperatures are still in the 20s. Additionally, rain may wash away salt already laid down, requiring additional salting throughout the evening to prevent icing on frozen ground surfaces from additional rainfall.
