Despite a bit of rain, Iowa's drought worsened in the past month, according to the director of the U.S. Department of Agriculture's Midwest Climate Hub. Dennis Todey says prospects for the rest of the summer are hard to forecast. At best, Iowa would get enough rain to hold off an even worse drought, he predicted. Todey says the drought is the worst in 20 years, and the long-term forecasts don't call for much rain in the Midwest in the next week.
