Alert Details

An active weather pattern is expected to continue for the next five days across much of the corn-growing region. As a result, Low corn earworm migration risks are present off and on throughout the forecasting period. A Low risk is in place tonight into Saturday morning especially east of a Paducah, Kentucky to Detroit, Michigan line into the western Appalachian Mountains as south to southwest winds continue to the east of a cold front. Showers and thunderstorms are also expected to be widespread east of the front so moth flights may be more limited. After a weekend with no risk, Low risks return to the Plains and western/central corn-growing region (mainly west of Lake Michigan) by Monday night and further east into the southwestern Great Lakes region and eastern Midwest by Tuesday night into Wednesday morning as the next cold front moves in and southerly winds increase to the east of the front.
