Daily Feature

Date: 11 Aug 05:30 AM
Votes: Good: 9
Bad: 1 Abstain: 0
The near daily deluges of rainfall impacting somewhere in Iowa continued over this past weekend. The Dubuque airport was the deluge recipient on Sunday with a daily total near five inches, which is a top 10 rainfall on record for the site. The featured chart presents the top 10 daily rainfall events for the long term data from Dubuque, which dates back to 1873! The 2011 event was covered by an IEM Daily Feature showing the one minute interval precipitation. The data for this event won't fully come in until Monday evening. While there is more chances of rain in the forecast this week, it does look more dry than wet, which would be good news for most Iowans and for Iowans wishing for fair Iowa State Fair weather!
