UPDATE 8:20 P.M.
Stearns, Wright, Carver, Dakota, Hennepin, Scott, Freeborn, Rice and Steele counties have been added to a severe thunderstorm watch until 2 a.m. Saturday. Storms are likely to intensify and move east-southeast on a line and target areas roughly in an area from Minneapolis to Mankato and points to the east/southeast.
Here's what the radar looks like as of 8:25 p.m. These are the storms that are tracking across Minnesota.
A severe thunderstorm watch has been issued for an area of southwest and south-central Minnesota, with the National Weather Service saying severe storms will be isolated, but those that do reach severe levels will be capable of producing large hail and damaging winds.
Specifically, hail could reach the size of ping pong balls and damaging winds could reach 70 mph. The watch does not include the Twin Cities metro area.
The radar simulation from the HRRR model shows a strong cell near the South Dakota-Minnesota border developing into a cluster of storms that could move through the watch area this evening into tonight.
