| Episode narrativeepisode_narrative | An eventful day played out across Iowa, carried out in two parts. First was a wave of strong to severe storms during the morning hours across much of northern Iowa, followed by a subsequent wave of storms across southern Iowa. Respectively, the storms produced primarily severe hail and then severe winds and heavy rainfall. ||Environmentally, the setup was relatively prime for organized convection and to a degree, training storms. A relatively stationary front (slowly drifting southward later in the day) laid across Iowa from southwest to northeast throughout the day on the 28th. On the warm side of the boundary, MUCAPE values were in excess of 2000 J/kg already early in the morning, growing to 3000-4000 J/kg by the afternoon. Other supporting factors for organized convection were present as well, including 40 to 50+ kts of effective bulk shear, hail CAPE in excess of 600 J/kg (especially in the morning round), and effective storm relative helicity around or in excess of 200 m2/s2. Understandably, composite indices such as the significant hail parameter and the supercell composite parameter returned values that raised concerns for severe weather potential. ||At the end of the day, reports were split into two distinct areas. The first was large hail over northern Iowa with the early morning convection, followed by damaging winds and heavy rainfall with the afternoon and evening convection over southern Iowa. |
