Severe to exceptional drought conditions existed in nearly 90% of the state according to this week's U.S. Drought Monitor with slightly more than half of the state in extreme drought conditions or worse. Only about 10% of Indiana had abnormally dry to moderate drought conditions. The dry conditions have caused nearly all counties in Indiana to issue burn bans.
Drought conditions in portions of central and southern Indiana were worse than the Dust Bowl Days of the 1930s. From June 1–July 17 much of central Indiana had received less rainfall and been nearly as hot as the summer of 1936. Several areas of northern and east central Indiana received one-half to nearly 4 inches of rainfall from July 17-July 19 while portions of central and southern Indiana remained dry or nearly dry.
Indiana will experience a small break in the hot weather today before another heat begins on Saturday. Recent rainfall has tempered current drought conditions especially in portions of northern and east central Indiana. This rainfall will not break the drought. What is needed to end the drought is a return to regular weekly rainfalls averaging about an inch. Instead, hot and mostly dry conditions will return the week of July 22.
The effects of the drought were having a large impact on Indiana agriculture. Late season crops, like corn and soybeans, may see their worst yields since the Great Drought of 1988...possibly even lower. Wildfires continue to be a daily threat which is rarely seen in Indiana in July. The Indiana Department of Natural Resources issued a warning to boaters about low lake levels at the peak of boating season for some area lakes. The City of Indianapolis and several nearby metro communities have issued mandatory outdoor water restrictions. The State of Indiana issue the first ever water shortage warning asking for a voluntary reduction in water use. Local wells have gone dry in some central Indiana areas.
