Another Big August Rainfall

Posted: 21 Aug 2018 05:37 AM, Views: 504
Another big rainfall event this August impacted the state with the featured map depicting rainfall estimates since Saturday and the US Drought Monitor overlain. Just to our west, Omaha, NE nearly set its one-day rainfall record with a total over six inches on Monday. Some portions of extreme southern Iowa again missed out on the most significant rains, but some recently dry areas picked up needed rain. The expansion of drought coverage that was done last week will likely be mostly reverted this week. The worst off areas for drought near and south of Ottumwa really missed out again.
