Episode narrativeepisode_narrative	A weak cold front entered the state during night of the 2nd into the early morning hours of the 3rd. The airmass became unstable ahead of the front, though not as unstable as is typically the case in early August. CAPE values were in the 2000 to 4000 J/kg range with lifted indices around -6 C. Precipitable water values were generally three quarters of an inch to one inch. During the day temperatures warmed into the 80s with dew points generally in the upper 50s to mid 60s. Dew points pooled just ahead of the front and were between 65 and 70. The freezing level was quite high, between 14,500 and 15,000 feet. Thunderstorms developed over southeast South Dakota and northwest Iowa during the evening. They moved southeast and accelerated to around 50 MPH during the late night and early morning hours. Many of the storms produced hail, however hail was generally around an inch or less in diameter. One and one quarter inch diameter hail fell in Clarke County, northeast of Osceola. One of the stronger clusters of storms produced quarter to golf fall size hail in a swath from Schleswig to Denison in Crawford County. The hail stripped leaves from trees and caused extensive crop damage. Strong winds were produced as the storms moved into the northwest part of the Des Moines CWA. Considerable tree and power line damage occurred in Pocahontas, Humboldt, Webster, and Carroll Counties. Reports indicated that power was knocked out to about 10,000 homes. As the storms moved through Story County, lightning struck a house northeast of Nevada. A power pole was struck and the power line was on the house. A fire resulted causing some damage to the home.
