Rain and scattered thunderstorms will impact the region at times

will be from 10 pm to 4 am. The thunderstorms will produce heavy
rainfall, small hail and gusty winds. Rainfall runoff on frozen

Minor snow and ice accumulations will occur over far north
central Wisconsin Saturday morning, and may result in locally
hazardous travel.

jams on susceptible rivers through early next week.
