Alert Details

A cold front will work its way southeast through the corn-growing region but at a somewhat slow pace this week. To the east of the front, showers and thunderstorms are likely on a periodic basis and with south to southwest winds in place, the potential is there for some isolated corn earworm moth flights to occur. Low risks are in place tonight into tomorrow morning especially from eastern Kansas and Missouri northeast into Iowa, southern Wisconsin, Illinois, Indiana, Ohio, and lower Michigan. As the front only moves slightly further to the southeast tomorrow night into Friday morning, the risk area focuses mainly from Missouri and eastern Iowa east into the southern Great Lakes region and eastern corn-growing region. Finally, by Friday, the front looks to get a stronger push to the east and that should confine most of the migration risks to the far eastern corn-growing region from Indiana and Ohio into southeast lower Michigan and southern Ontario, Canada. Fresh market and vegetable growers should pay close attention to this risk as some crops may be at a critical stage of growth at this point and some damage could result from these flights.
