Snow accumulations of 2 to 5 inches are expected later this evening through tonight for areas along and south of I-94. Locally higher amounts will be possible. The expected area of highest snow totals may shift a little north or south.
A round of snow showers is expected Wednesday evening, with an inch possible. Gusty winds of 30 to 35 mph will result in some blowing snow.
Arctic air returns to southern Wisconsin for the weekend. Dropping temperatures and increasing winds will cause wind chills of -20 to -40 across the area.
