Alert Details

A predominantly northwest to southeast flow weather pattern is predicted across much of the corn-growing region into next week. As a result, corn earworm migration prospects are rather low, if any, through the next five days. There is a low pressure system in the far western Plains with a warm front to its east, and to the south of this front, southerly winds will provide the opportunity for at least isolated moth flights especially into the southwest portion of the corn-growing region. Low risks are in place tonight into tomorrow morning mainly across Kansas, southeast Nebraska, southwest Iowa, and northwest Missouri. The risk spreads northeast slightly tomorrow night into Friday morning, and includes fields mainly south of I-80 and west of I-35. No other risks are predicted in the next five days as wind flow is predicted to be weak or disorganized.
