| Episode Narrative |
A cold front moved southeast across the state during the evening of the 17th into the early morning of the 18th. The surface front reached southeast Iowa, however the upper level front lagged behind the surface front and remained over northern Iowa. The airmass was relatively unstable for mid September, with CAPE in the 2000 to 3000 J/kg range and lifted indices around -5 to -7 C. Precipitable water values were around 1.5 inches. The effective wind shear was in the 30 to 40 kt range. Thunderstorms formed on the elevated front. Clearly, the storms were elevated in nature and produced little wind as they passed. Many of the storms produced small hail. One of the stronger storms over Sac County produced penny to nickel size hail near the town of Early. The thunderstorms continued to develop during the day. Nickel size hail fell southwest of Dow City in Crawford County during the late morning hours. |
