Episode narrativeepisode_narrativeA strong frontal boundary was stretched across Iowa. At the same time a 35 kt low level jet pushed warm and humid air into the frontal boundary. There was a reasonable amount of elevated instability with 1000 to 1500 J/kg available. The atmosphere was strongly sheared with 50 to 80 kts of effective shear available. Though the CAPE in the -10 to -30 C layer of the atmosphere was not all that high, it was in the 200 to 400 J/kg range. Precipitable water values were greater than 2 sigma above normal, in the 1 to 1.25 inch range. A broad southwest flow was present over the region with a closed upper low over the southwest U.S. A short wave lifted northeast and interacted with the frontal boundary during the morning. An MCS formed, producing heavy rainfall and hail of nickle to quarter size in parts of central into northeast Iowa. The largest hail fell near Stratford in Hamilton County. It was half dollar in size. Several areas received 1 to 2 inches of rain in the 24 hour period ending the morning of the 9th. The heaviest was in Webster County near Stratford with 3.73 inches.
