Severe Storm Watch Until 1 AM Thursday. Conditions are ripe for strong to severe storm over much of southern Minnesota as warm, moisture-laden air surges northward, coupled with powerful jet stream winds aloft. The watch includes Mankato, Rochester, Hutchinson and the Twin Cities. The greatest risk is large hail, but a few isolated tornadoes can't be ruled out, along with training echoes capable of flash flooding in some communities. Details from NOAA:
