A Slight Risk for severe weather exists over southern Wisconsin late this afternoon into this evening, primarily for large hail. A Winter Weather Advisory is then in effect from 1am to 1pm Wednesday over central to east-central Wisconsin for travel impacts from freezing drizzle.
After the storms, cold air will intrude from the northwest. Freezing drizzle will take hold north of I-94, with a light glaze of ice expected in the advisory area by daybreak Wednesday. A changeover to light, wet snow will then sweep in from the northwest after dawn.
