Episode narrativeepisode_narrativeA very humid airmass was in place over Iowa as southerly flow drew moisture north from the remnants of former Hurricane Alex. Precipitable water values rose to over 2 inches over most of the CWA with most between 2.2 and 2.85 inches. These values represent record high values. Instability was marginal with 1000-2000 J/kg of CAPE available. The atmospheric column was nearly saturated to above the freezing level, which was at 16,500 feet. Very little lightning occurred as the rain was mainly tropical in nature. A band of moderate to heavy rain developed from southwest through central into northeast Iowa. A narrow line of strong thunderstorms developed from southeast Wayne County, northeast through Appanoose County, into northwest Wapello County. Rainfall rates were 1 to 2 inches per hour. At the Rathbun dam, in Appanoose County, 6.89 inches of rain fell in a few hours. West of Seymour in Wayne County, 4 inches was recorded. Flash flooding occurred from Appanoose County northeast into Wapello County. Water was flowing over roads over a foot deep northeast of Blakesburg in Wapello County. Flash flooding was also reported with roads under water southeast of Rathbun Lake in Appanoose County.
