Flooding is happening in Minnesota a dry pattern coupled with perfect snow melting pace has kept the catastrophic potential from coming into existence. Now all eyes turn to severe weather season, which is next in line with Minnesota's ever-changing weather.

  • Start to 5:39 - MN dodged potential catastrophic flooding. 
  • 5:40 to 12:20 - 21st anniversary of the Comfrey/St. Peter EF-4 tornado. 
  • 12:21 to 13:37 - Details about the famous 'Wizard of Oz' tornado. 
  • 13:38 to 18:00 - We're entering severe weather season. 
  • 18:01 to end - Recapping Blumenfeld's show at Bryant Lake Bowl. 

"Spring is a great time for severe weather because the atmosphere is heating up," explains Blumenfeld. "Part of what's driving these severe weather systems is the vertical contrast in temperatures – warm, humid conditions at the surface and then very cold air aloft."

June is historically the most active month for severe weather in Minnesota, but any time generally from April through September, sometimes as early as March or even as late as October and November, it's possible.

"It favors spring and early summer because the atmosphere is heating up and there's still enough cold air in place aloft to get that temperature contrast going," Blumenfeld says. "Then all you need is the jet stream nearby and that provides a lot of wind energy aloft and storms that get going can start rotating."
