Snow will develop across northern Iowa tonight. The snow may become heavy at times late tonight into the day on Tuesday, especially across far northern Iowa. Further south, a wintry mix of snow, sleet, or freezing rain is expected.

Within the winter storm warning, total snowfall amounts will range from 6 to 8 inches near the Iowa/Minnesota border to 2 to 4 inches along the US Highway 20 corridor. Strong and gusty northwest winds will also develop with wind gusts over 40 mph possible by Tuesday afternoon. These winds will cause areas of blowing snow and hazardous driving conditions.

The winter storm warning will be in effect from 1 AM Tuesday to 1 AM CDT Wednesday. Plan on difficult travel conditions, including during the evening commute on Tuesday. Expect significant reductions in visibility at times. A winter weather advisory will also be in effect during this timeframe too. This is where 2 to 4 inches of snow can be expected.
