Much of Iowa has seen a number of intense rainfalls this year. The featured chart presents the average daily precipitation on days with precipitation reported for each year for Ames. A long term mean, a mean calculated over the 1981-2010 period, and a trailing 30 year mean is shown as well to look for changes. This analysis does not show much change as they all are around 0.35 inches. If you assume a rough 35 inch per year annual total, you can back out around 100 days per year with precipitation which equates to 2.5 days per week with precip. The rain chances this week look to come around mid-week.
