IEM Daily Feature

Hit or Miss Showers

Posted: 17 Aug 2018 05:35 AM, Views: 838
Showers and Thunderstorms were plentiful over the state on Thursday, but not everybody got rain. The featured map is of estimated precipitation totals derived from RADAR for the day from the Iowa Flood Center. A rather blotchy map presentation is shown and as has been typical for much of this summer, areas over southern Iowa mostly missed out on the action. The best chances for rain over the area arrive next week.
