Missouri River Basin Drought Early Warning System

Conditions for the week of April 11-17

Heavy snow also blanketed portions of the northern Plains, while dry, windy weather dominated drought-affected areas of the central Plains.  The storm contributed to the elimination of severe drought (D2) from the Dakotas, and brought substantial reductions in the coverage of abnormal dryness (D0) and moderate drought (D1).  In South Dakota, 2-day April snowfall records were broken on April 13-14 in Mitchell (16.2 inches) and Huron (15.5 inches), while peak gusts were clocked to 60 and 57 mph, respectively.  Sioux Falls, South Dakota, received 14.5 inches of snow from April 13-15, and reported a gust to 67 mph on the 14th.  Most of Sioux Falls’ snow—13.7 inches—fell on the 14th, easily becoming the snowiest April day on record in that location (previously, 10.5 inches on April 28, 1994).
