August 8th
Sherburne, Isanti and Mille Lacs Counties
Our storm going up as myself and Theresa Caspsers wait in Monticello, MN.  This ended up being a pretty eventful chase with everything from a weak TOR to a car in the ditch requesting help to copious pea sized hail driven in 50 mph winds bringing I35 north to a halt!
