Episode narrativeepisode_narrativeA weak, relatively stationary boundary, was situated from west to east across Iowa throughout the day. Surface conditions reached a balmy mid to upper 90s south of the boundary with dew points well into the 70s, while north of the boundary conditions were not much better with dew points in the 70s and temperatures in the upper 80s to low 90s. The convective environment resulted in MUCAPE values exceeding 5000 J/kg across southern Iowa and at least 2000 J/kg available across far northern Iowa. Best effective shear values were located near and north of the boundary where 30 to 40 kts existed. Storms initially developed in Nebraska and propagated near/along the boundary eastward into Iowa. The primary results were damaging winds and borderline hail. In a few instances, storms initiated ahead of the main batch, allowing for some locations to experience extended periods of heavy rainfall to the tune of 2 to nearly 4 inches.
