Heavy thunderstorms moved through the Twin Cities on Friday morning, and more are expected to develop Friday afternoon and pose threats of large hail, damaging winds and even a tornado or two.
The Twin Cities is under a marginal risk of severe storms, with the best chances for the aforementioned hazards existing in southern Minnesota, from just north of the Mankato area to points south an east.
This from the Storm Prediction Center, as of their 11 a.m. update: "the conditional environment is favorable for rotating storms capable of large hail and perhaps a tornado or two if persistent convection can occur."
The earlier storms produced hail the size of quarters in the west metro, like this sample from someone in the Mound area.
Certainly be weather aware if you're headed outside to the Minnesota State Fair. People at at the fair during the morning round of storms had to run for cover due to torrential rain and intense, frequent lightning.
