Hail up to ping pong ball sized and wind gusts estimated up to 40 mph.

Wider weather episode

The remains of an MCV that tracked across Nebraska earlier in the day moved into Iowa in the late afternoon. These remnants moved into a deeply unstable environment with 2000+ J/kg of SBCAPE and intensified through the early evening, transitioning to a loosely organized bowing segment in the evening. Steep mid and low level lapse rates and DCAPE of 750-1000 J/kg were also available. This combination resulted in a handful of hail and damaging wind gusts across the area. Heavy rain also occurred as a line of training convection developed behind the bowing segment lasting late into the night. A swath of 3 to 5 inches of rain occurred with the system in central to southern Iowa, however no flood impacts were noted.
