Two Inch Rainfall Impact

Posted: 17 Aug 2022 05:30 AM

Sioux City's rainfall woes have been the subject of a number of IEM Daily Features this year. The airport picked up almost two inches of much needed rainfall on Monday. Did the rainfall put a dent into the deficits for the location? The featured chart presents six different trailing day precipitation metrics. The values represent the given x-axis date until Tuesday. Of course, the impact of the event on the very near recent term is significant as a two inch rainfall will far surpass climatology. But as one starts traveling back in time to early June and even to April, there are still substantial deficits to make up. The US Drought Monitor from last week has the location at D3 classification. Note that the Drought Monitor is representative of larger areas than just a point, but point data is considered in the analysis. So while the two inch rain may help boost the area to D2 classification for this week's update to be released on Thursday, significant deficits still remain and more rainfall would certainly be welcome!
