Episode narrativeepisode_narrativeA predominantly stalled out east-west oriented surface boundary found itself situated across southern Iowa on the 11th and drifted slowly into northern Iowa by the 12th. Given the boundary location, storms that initiated were elevated in nature and predominantly limited to a hail and heavy rain threat. The convective environment contained MUCAPE values throughout this time frame in the 1000-2000 J/kg range coincident with roughly 30-40 kts of effective bulk shear. Generally, convection was initiated with the aide of the low level jet, leading to relatively widespread multi-cellular clusters versus discrete cells. In all, severe hail was difficult to come by, while heavy rainfall was more prevalent in the 1.5 to 2.5 inch range.
