Here comes flood season.

Our rapid warmup is quickly melting snow across our region this week. Rivers are already rising quickly in many areas. This time-lapse of the Clam River in northwestern Wisconsin shows the trend.

The National Oceanic and Atmospheric Administration’s snow water equivalent report still shows between 2 and 6 inches of water in the snowpack across Minnesota in areas north and west of the Twin Cities.

With temperatures moving from the 50s to the 80s, that snow is going to rush into rivers at a quickening pace.
