Most Dangerous T-storms over Southern Minnesota. A (Doppler-indicated) Tornado Warning remains in effect for Mankato - the storm most likely to spin up tornadoes either side of I-90. Heavy rain is likely in the Twin Cities metro, a developing MCS system may brush southern suburbs with small hail and torrential rains capable of flash flooding. These storms closer to the Iowa border have a history of ping pong size hail and wind gusts to 85 mph. NWS Doppler radar at 6 PM.


New Tornado Watch Southeastern Minnesota. This new watch, valid until 1 AM Tuesday, includes Rochester, Austin, Winona and La Crosse, WI, but it does not include the Twin Cities metro.

Developing MCS? Although heaviest rains may pass just south of MSP early tonight it still looks ripe for extreme rains over southern Minnesota and southwestern Wisconsin, where some 2-4" amounts are possible.
