| Episode Narrative | An unseasonably strong storm system aloft was located over the northern Rockies. This produced a very strong northward push of moisture into Iowa. After the initial convection from the morning moved out of the area, some clearing spread into the southwest, west central, and parts of central Iowa. The atmosphere became very unstable with lifted indices falling to between -5 and -8 C. MUCAPE increased to around 4000 J/kg by evening. The low level jet increased to around 75 kts, feeding the storms well into the night. The environment was quite sheared with 40 to 65 kts of effective shear. Hail was limited in spite of the 400-500 J/kg of shear available in the -10 to -30 C. layer of the atmosphere. The freezing level was very high for mid June, around 15,200 feet. Downdraft CAPE was between 1000 and 1300. Precipitable water was around 1.6 inches. The LCL was in the 750 to 1250 meter range. An intense line of thunderstorms formed from eastern Nebraska into central Kansas. One tornado touched down in Crawford County near Charter Oak. Many of the storms produced pea to marble size hail, with the stronger storms producing hail around nickel size. After sunset, the storms became more wind producers. There were several reports of 60 to 70 MPH winds with considerable tree damage. The highest winds were 75 MPH in Webster County at Duncombe. The big story became the heavy rain. Many of the storms produced rainfall of 1 to 2 inches per hour, with some areas reporting total rainfall of up to 4 or 5 inches. With the very wet soil conditions across the state, it only took between 1/2 and 1 inch of rain to cause flash flooding. Water was reported across roads in many places across the state. Flash flood warnings were issued for over half of the Des Moines CWA by the time the night was done. |
