Greater than 4 inches of rainfall over a 24 hour period were reported yesterday in a number of locations in Southwest Iowa. According to IEM databases, this is the 8th day this year with 2 or more COOP sites reporting 4+ inches of rain! The featured chart shows 2007 having 2 more days of heavy rainfall events than any other year since 1951. This statistic was computed only considering sites with an observational record back to 1951. Unfortunately, the result of this graphic has been numerous flood events over nearly all parts of the state.
