motion moving from

no forward surge...????
Possibly forming into a
roll cloud?  Not in the
correct position????

Zimmerman, MN at
junction of Sherburne
CR4 and highway 169.
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!
Southwest of
Zimmerman, MN
looking at wall cloud,
RFD occlusion and
