Areas of Dryness in Illinois in July

While much attention has been given to the areas of heavy rain in Illinois, there were two areas of significant dryness in the state in July. A product from the NWS that combines radar estimates and rain gauge measurements better defined those areas. See figure below.
One area of dryness in July was across north-central Illinois. Amounts in this area were only 25-75 percent of normal. Fortunately, this area received ample rain in June. Even so, the drying of the topsoil is clear in the August 2 USDA NASS Illinois Weather and Crops report.
The other area of dryness in July was in southern Illinois, south of I-64. This area was dry in June as well. As a result of two consecutive months of dry weather, the U.S. Drought Monitor designated this area as “abnormally dry.”
