The streak of dry weather ended for some on Tuesday as showers and thunderstorms visited Iowa again. For Des Moines, the streak was 16 days since the last measurable precipitation event. The featured chart presents the longest dry streak per year since 1893. Each year has seen at least one 10 day period of dry weather with the mean being around 3 weeks long. The bottom chart presents the number of dry streaks that last at least 7 days. The 2010 total is the lowest since 1998, but there are still 2.5 relatively dry months to go this year, so the total will probably be added to.

Good = 16
