Episode narrativeepisode_narrativeOvernight convection originating in south central South Dakota made its way across southern South Dakota overnight and eventually turned southeast as it approached Iowa. Through the morning hours conditions along and ahead of the line of convection included 30 to 40+ kts of 0-6km shear roughly orthogonal to the line, MUCAPE values in excess of 2000 J/kg, precipitable water values in excess of 1.5 to 1.75 inches, and consistent moisture transport into the region. All in all, a setup for consistent and sustained convection through the morning and afternoon hours. Fortunately, with the progressive nature no updrafts were able to produce severe hail. Given the linear nature, numerous reports of strong winds were received, but only a couple severe level reports. Additionally, heavy rainfall was reported with a few locations picking up in excess of 2 inches.
