Episode narrativeepisode_narrativeThe setup over Iowa was primed for a heavy rainfall event for a few reasons, including persistent SW 500 mb flow, a strong and SW oriented 850 mb jet, strong low level moisture transport, and elevated CAPE around 1000-2000 J/kg. Precipitable water values, given the strong moisture transport into the area, rose into the neighborhood of 1.7 inches throughout the event as well. While effective bulk shear values were supportive of organized convection, that generally did not come to fruition given the widespread lifting with persistent low level warm air/theta-e advection and 850 mb jet into the region. As a result, the vast majority of reports and general consequences revolved around heavy rainfall and flooding, including a number of road closures. A couple severe wind gusts and damage reports were received in addition to the water issues.
