Midwest Drought Early Warning System

Conditions for the week of May 9-15

Warm, wet weather in southern portions of the region compared with dry albeit cooler conditions farther north. A wide area of moderate to heavy rain (an inch or more) was observed from Missouri and Iowa eastward into the lower Great Lakes Region. Rainfall locally topped 2 inches, resulting in modest reductions in Abnormal Dryness (D0) and Moderate Drought (D1) across Missouri, Iowa, as well as northwestern Minnesota. However, the heaviest rain largely missed the lingering core drought areas, so overall the central Corn Belt’s drought depiction remain largely unchanged. Farther north, increasingly dry conditions over the past 60 to 90 days (25-60 percent of normal) led to an expansion of D0 and D1 in northern portions of Minnesota and Wisconsin as well as the upper peninsula of Michigan, particularly in areas which reported less than 0.5 inch of rain during the 7-day period.
