Severe Storms Return Saturday 10/21

A cold front will be approaching the state by Saturday afternoon, which will bring much cooler temperatures and the potential for severe storms.

By 3pm Saturday, the cold front will begin to enter into western Iowa. This is when storms are expected to develop, and will continue over the next few hours along the cold front. Due to storm mode being linear, this will pose mainly a damaging wind threat. However, if low level winds can remain backed out of the southeast ahead of the front, a spin-up tornado threat cannot be ruled out.

Iowa Tornado Potential

This line of storms will continue to the east, and will be around the I-35 corridor by 7pm. As evening begins to set in, storms will begin to weaken in strength. By 11pm, storms will be entering into eastern Iowa, and by this time, will mainly be producing frequent lightning and some gusty winds.
