2+ inch rainfalls

Posted: 09 Jul 2010 06:11 AM

The featured chart looks at the percentage of long term climate sites that observe a greater than two inch rainfall per year. There are 104 sites in Iowa, that the IEM has precipitation data back to 1951, used for this chart. Based on IEM estimates for 2010, roughly half of these locations have seen a 2+ inch rainfall, which is behind the pace set in the past 3 years. The dots represent the final total for the year with 2007/2008 sticking out as almost every location in the state experiencing a heavy rainfall event. Another take home message of this plot is that more heavy rainfall events will occur as summer is only a few weeks old.
