Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

eventually east and southward and the severe threat has been
pushed south of the dvn cwa. It will be cooler with highs in the

regime with daily highs in the 70s to lower 80s. Thunderstorm
chances return late in the week into next weekend.
