Episode narrativeepisode_narrativeGenerally speaking, there was not much to write home about with regards to the synoptic setup for severe or highly impactful weather. Even so, an environment with nominal MUCAPE (often under 1000 J/kg), high shear (0-1km shear in excess of 30 kts, 0-1km helicity in excess of 200 m2/s2), and consistent low level moisture transport was able to produce weak, brief tornadoes and sustained periods of moderate to heavy rainfall. ||Specifically on the tornadoes, two brief weak tornadoes occurred in the relatively low CAPE, high shear environment in central Iowa. Little impact was observed from the tornadoes as they stayed in rural areas and away from structures and towns. ||On the rainfall front, multiple rounds of showers and storms produced numerous reports of 2 to 3 inches of rainfall throughout southern Iowa, even trickling north into central Iowa in a few instances.
