Tornado Watch until 11 PM. Many of the ingredients necessary for supercell thunderstorms are converging on central and eastern Minnesota. Bemidji, Brainerd, St. Cloud and the Twin Cities are all in the watch area, along with much of the St. Croix River Valley. Stay alert this evening - most of us will just see a heavy thunderstorm, possibly some small hail, but large hail, damaging straight-line winds and a few isolated tornadoes can't be ruled out. More details on the watch from NOAA SPC:
