Missouri River Basin Drought Early Warning System

Conditions for the week of May 15-21, 2019

Half an inch to over 2 inches of precipitation fell across much of the High Plains region this week.  But there were some strips which received 0.25 inch or less, including parts of eastern Nebraska, northern North Dakota, southwestern Wyoming, and southeastern Colorado.  Abnormally dry (D0) conditions expanded in the northern counties of North Dakota. In Colorado, on the other hand, recent precipitation, low evaporative demand in recent weeks, improving long-term moisture conditions, and hydrologic rebound from snowmelt prompted a reduction of D0 in the remaining areas of the state.
