A change in weather ahead
A large area of high pressure aloft will continue to prevail over the central United States through the start of the Holiday Weekend. This will result more hot and humid weather over central Illinois, with highs in the lower 90s through Sunday. Then, a cold front is forecast to move through late Sunday, bringing a return to more seasonal temperatures for Labor Day.
Meanwhile, after the significant rainfall which occurred this past spring, it appeared that thoughts of drought had come to an end. However, dry conditions that have persisted since June and intensified in August have regenerated drought conditions. In fact, the latest U.S. Drought Monitor indicates west-central Illinois in a moderate drought, with abnormally dry conditions extending farther to the east and north.
