| episode_narrative | A strong upper level ridge of high pressure developed over the Rockies during the previous several days. The weather pattern became a pattern more typical of July and early August rather than May as convection became established in the classic "ring of fire" configuration. Thunderstorms erupted during the night of the 12th and early morning of the 13th. The convection was all elevated in nature. The severe weather took the form of hail with this event. A deep layer of cool air at the surface was in place, limiting the threat of the storms becoming tornadic or producing high winds. Thunderstorms moved southeast across the state for about 12 hours. Many of the storms produced large hail. During the late morning into the early afternoon of the 13th, thunderstorms back developed over central Iowa, then trained southeast into south central Iowa. Heavy rainfall occurred just to the south of the Des Moines area in Warren County. Two and one half inches of rain fell in under two hours time in the town of Norwalk. Rainfall from the event was in excess of four inches in places, especially the southwest half of the county. Roads were reported under water, including some state highways. Hail was widespread with this event. with numerous places from northwest into south central Iowa reporting hail anywhere from three quarters of an inch in diameter, up to golf ball size. There were numerous reports of damage to vehicles as well as the roofs of houses. The largest hail occurred in the Atlantic area of Cass County. One of the stronger storms on the southwest edge of the convection dropped hail up to three inches in diameter on the city. The hail caused considerable damage around town to both roof tops as well as many cars. |
