| Episode narrativeepisode_narrative | Two atmospheric shortwaves provided forcing along a boundary oriented from west to east over central Iowa on July 10th, 2025, leading to multiple rounds of storms that afternoon and evening. The first of this activity developed as weak supercells in south central Iowa. Afternoon storms produced strong winds and a few funnel clouds, one of which prompted a tornado warning. This activity persisted into eastern Iowa but generally dissipated in central Iowa after sunset.|Later in the evening, convection over Nebraska progressed eastward into Iowa, organizing into a more complex line of storms and taking advantage of the unstable environment along the boundary. This organized line of storms, known as a Mesoscale Convective System (MCS), brought very strong, damaging winds to locations along the Interstate 80 corridor. Weather stations and spotters measured winds as strong as 74 mph and estimated wind gusts approached 80 mph near Panora. There, entire trees were snapped or uprooted, shingles were torn off of homes, and HVAC units were ripped off of the Panora City Hall. However, wind damage was not limited to Panora, with damaging winds reported across most counties along Interstate 80 leading up to and including the Des Moines metro area.|After passing through the metro, damaging winds generally diminished into east-central Iowa, although sub-severe winds did continue with the MCS. While the severe winds ended with the departure of the MCS, the parent shortwave remained to the west of the state, producing forcing for heavy rainfall along the boundary through the overnight hours. This prolonged, heavy rainfall prompted a flash flood warning over central Iowa into the morning hours on July 11th, 2025. |
