Thunderstorms are likely this afternoon and evening, including the potential for severe storms, according to the National Weather Service in La Crosse.

Southeast Minnesota is under a Flash Flood Watch in effect until late tonight.

The main hazards will include damaging winds, hail and heavy rain, with an isolated tornado also possible.

There is the potential for flooding, especially if storms repeat over the same areas, and rises will occur on area rivers and streams.


  • Flash flood watch has been issued for the entire area, in effect through tonight; additional rounds of heavy rainfall on already saturated ground will lead to quick runoff and rises on area rivers.
  • Showers/storms currently progressing northeast through the area early this morning will be followed by a decaying line of showers/storms arriving later this morning.
  • A more significant line of showers and storms will develop this afternoon, progressing eastward through late evening; some severe storms possible with damaging winds and large hail as the main threats. Isolated tornadoes also possible.


  • Round of showers and some storms moves through this morning.
  • Final round of showers and storms will move through this afternoon-late evening.


  • Medium to high confidence in heavy rainfall and localized flood impacts
  • Medium confidence that some storms this afternoon/evening may be severe, mainly south of I-90
