Midwest Drought Early Warning System

Conditions for the week of July 11-17

Warmer than normal temperatures occurred over most of the Midwest region. Heavy rain impacted much of Minnesota and Illinois, while heavy rain was spottier in parts of Missouri, Iowa, Indiana, and Ohio. In several areas that missed out on heavier rainfall, conditions degraded. Extreme drought conditions expanded in northern Missouri into a small part of southeast Iowa, where long-term precipitation deficits and warm conditions led to degrading conditions. Short-term precipitation deficits caused moderate drought to expand in the Michigan Upper Peninsula. Short-term dryness also led to abnormal dryness developing in west-central Missouri. Precipitation deficits and high temperatures led to the development of abnormal dryness over parts of northern Ohio and the southern Michigan Lower Peninsula. Short-term dryness also was noted over localized areas of central and eastern Wisconsin, the latter of which saw conditions degrade to abnormally dry. Short-term dryness ended in most of western Minnesota after a heavy rain event.
