Forecasters expect the nasty weather to be clear of the Twin Cities by the Monday morning commute. KARE-11 reports the freezing rain turned to snow a little earlier than expected, so final snowfall totals could reach three inches.
The Weather Service's La Crosse bureau says in areas south of Interstate 90, freezing rain could still keep the roads messy through Monday morning.
