Missouri River Basin Drought Early Warning System

Conditions for the week of April 19-25

Wet weather brought relief to the southern half of the region, while conditions remained unchanged on the northern long-term drought areas. Precipitation amounts were highly variable, but well-placed moderate to heavy rain and wet snow (1-3 inches liquid equivalent, locally more) led to reductions of Abnormal Dryness (D0) and Moderate Drought (D1) over southern-most portions of Wyoming, northern and northeastern Colorado, as well as the northwestern and southeastern corners of Kansas. Additional D1 and D0 reductions were made from eastern Colorado into southwestern Kansas despite lighter rainfall (half inch or less), as precipitation totals over the past 90 days were now mostly well above normal, with 30-day totals locally more than three times normal.  Meanwhile, despite resent wet weather, long-term deficits linger in the north’s D1 and D0 areas; 12-month precipitation stood at 65 to 80 percent of normal in northeastern Wyoming and adjacent portions of the Dakotas, though some parts of southwestern South Dakota were closer to normal and may be removed from D0 in the near future.
