Heaviest rains shift south

The front has shifted south, and the heaviest rains today will tend to be over northern Iowa but periods of rain and scattered thunderstorms are expected over much of southern Minnesota.

The Twin Cities metro area and central Minnesota could see some scattered showers and an isolated thunderstorm today and tonight.

The National Oceanic and Atmospheric Administration’s North American Mesoscale 4 km resolution forecast model shows the general rain pattern today through Saturday morning:

NWS Twin Cities

Mankato, Albert Lea and Rochester are among the cities in the flood warning.

The Twin Cities NWS will update the watches and warnings as we go through the day.
