Mild, and maybe a little wet. The Twin Cities have a 40 percent chance of rain Tuesday afternoon and a 50 percent chance at night, with a possible rain/snow mix at night. Daytime highs in the lower 40s; nighttime lows in the upper 20s. Statewide, daytime highs from the mid-30s in the northwest to to mid-40s in the southeast. Central, eastern and southeastern Minnesota have a shot at some precipitation at night as temperatures dip. More on Updraft. | Forecast
