Severe Weather Update #1 - July 24

Both a Severe Thunderstorm Watch and Tornado Watch have been issued for portions of the state. Currently the bulk of thunderstorm action is confined to the northeast corner of the state where a supercell is beginning to take on tornadic characteristics and has prompted the tornado watch issuance. This storm has moved through areas of northeast Iowa with hail up to 1.50" in diameter and winds of at least 60 mph causing tree damage and at least one injury in Cresco.

While this storm is currently only severe warned, the latest scans have indicated rotation beginning to tighten and this storm may become tornadic within the next hour. With conditions continuing to become favorable for tornadoes, the SPC has issued a tornado watch for portions of eastern Iowa where this storms path appears to be at this time.

Additional development along the cold front across northern Iowa may occur through mid-afternoon, thus the severe thunderstorm watch continuing in effect until 5 PM for portions of the state.
