Missouri River Basin Drought Early Warning System

Conditions for the week of June 14-21

While significant rains (1.5-3 inches) across northern and eastern North Dakota and northeastern South Dakota provided some relief, little or no rain worsened conditions across eastern Montana, western and southern North Dakota, and the western half of South Dakota. Dry conditions during the past 30 days also allowed for an expansion of abnormal dryness (D0) into central and southeastern Montana, northeastern Wyoming, central and northeastern Nebraska, and northwestern Iowa. With May-July normally the wettest time of the year in the northern High Plains (some areas typically receive half to two-thirds of their ANNUAL precipitation), a lack of adequate late spring and early summer rainfall can impact the region for the rest of the year.
