Missouri River Basin Drought Early Warning System

Conditions for the week of August 9 – 15

With the recent rainfalls, conditions returned to normal in northwestern Kansas along the Nebraska border. In southwestern Nebraska, moderate drought shrank (D1), following precipitation totals of up to nearly 4 inches. Likewise in the Nebraska panhandle, normal conditions prevailed once again, thanks to precipitation totals of 1.5-2.5 inches over the past week. Heavy rain also erased remaining dryness in Laramie County, Wyoming. Conditions improved to abnormally dry (D0) in parts central Nebraska after two consecutive nights of heavy rainfall. D1 also shrank slightly in north central Holt and south central Boyd counties, where up to 3.5 inches of rain fell. And normal conditions returned to a swath from Ewing to Atkinson in Holt County. Some areas in South Dakota received 3-7 inches of rain over the past week, improving conditions in some northeastern, north central, and south central pockets. However, the western part of the state was not as fortunate. Extreme drought (D3) crept farther west in Meade County while severe drought (D2) expanded in Jackson. In southwestern North Dakota, rainfall helped alleviate exceptional drought (D4, the worst category), although due to the extremely poor growing conditions, it remained around the Hettinger County area.

In Montana, abnormally dry conditions extended southward to the Wyoming border. There have been recent reports of water shortages in Beaverhead, Madison, Gallatin, Jefferson, Park Counties. Ninety-eight percent of the topsoil is rated short to very short in Montana and fire danger is high.
