Short vs Long Term Drought

Posted: 04 Apr 2024 05:30 AM

Parts of eastern Iowa have received quite a bit of precipitation over the past seven days. The drought situation is certainly being helped out in this area, but not all sites have seen enough precipitation to put a significant dent into long term deficits. Case in point is Cedar Rapids, with just about an inch over the past nine days not registering much of a change in the longer term departure. The chart shows trailing 31, 91, and 365 day departures along with the weekly US Drought Monitor classification underlain. So while the short term departures are both slightly above average, the 365 day departure remains at significant levels below average.
