Alert Details

A cold front is expected to move southeast from the Plains states into the northern and central corn-growing region tonight into tomorrow. South to southwest winds, along with a very warm to hot temperature regime, are both expected east of the cold front. Despite many crops not being at a susceptible stage to corn earworm damage as of yet, there may be some vegetables and other hosts that may still be affected. As a result, Low corn earworm migration risks are predicted from Kansas, Missouri, and western Kentucky as far north as southeast Minnesota, Wisconsin, and southern lower Michigan tonight into tomorrow. As the front continues southeast, wind flow will shift more to the west and eventually northwest with the frontal passage, so additional risks are not anticipated after tomorrow.
