August 20th storms cause flooding and dangerous lightning


Video of some of the lightning seen August 20th 2014 Yesterday during the early morning hours, several thunderstorms developed along a stationary front that was trying to push through the area. The first storms formed around 5am and then after that, waves of thunderstorms developed on this front through the mid morning hours. flooding was seen especially in the Southewest metro area where 3-5" of rain was seen in parts of West Des Moines, Cumming and Norwalk. Lightning was vivid and extreamlly dangerous and close where thunderstorms developed, and heavy rain lead to flash flooding in some areas. The most intense band of rain was centered in a very isolated area from near Dexter to Cumming and Norwalk in the SW side of the Des Moines metro. Traffic was backed up for miles on 235, 35 and even the Highway 5 bypass as the heavy storms pushed through during morning rushhour. So far at least 1 report has over 5" that fell in Cumming and other report of 3.20" that fell in Earlham. 1.47" was reported at Des Moines international airport. In my raingauge about 2 miles ENE of Downtown Des Moines in the Fairmount Park neighborhood. 0.41" fell.
