D2 Introduction

Posted: 17 Jul 2020 02:40 AM

The big rainfalls of the past week have mostly missed the driest areas of the state. This week's US Drought Monitor update introduces the "D2" (Severe Drought) category to portions of west central Iowa. One such location and one of the driest locations in the state is Carroll. The featured chart presents the combination of trailing day sigma precipitation departures and the analyzed drought category at the time. The chart has a number of interesting stories to tell with the wetness at the end of 2019 now a distant memory as the long term (365 day) departure is now negative. The three month departure is where the trouble lies as rain has been difficult to come by this growing season.

Good = 16
Bad = 0
Abstain = 1
