A quick-moving weather system is expected to pass through the corn-growing region in the next 2-3 days. Southerly winds to the east of a cold front may spread a few moths to the north from southern source regions in Oklahoma, Texas, Arkansas, and Louisiana. Risks are initially across the Plains tonight and tomorrow morning but then spread east into more of the corn-growing region (as far east as Illinois, Iowa, southern Wisconsin, and Missouri) as the cold front moves east. After tomorrow night, the cold front moves into the eastern United States and high pressure builds into the Plains. Northerly winds will overtake much of the corn-growing region so no risk is predicted in the extended portion of the forecasting period.
