Iowa Tornado Update

This is the radar at 7:49pm. You can see the line of tornado reports at the bottom of the image as the storm moves almost straight east. The hook is just north of the right-most funnel cloud symbol.

The Doppler wind image from the same time shows two areas of rotation (circles). A tornado may be occurring in either or both locations.

CLASSIC tornado signature (circle) at 7:59pm.
