Alert Details

A cold front is expected to push through much of the corn-growing region this week in continued dominant northwest flow overall. A rather brief period of south to southwest winds is expected ahead of the front, and may pose an isolated corn earworm migration risk in some areas, especially near rivers given the stage of the moon right now. Low risks are in place tomorrow night into Thursday morning from northern Kansas and Missouri north into Minnesota, Wisconsin, and Illinois. Low risks then continue in the forecast Thursday night into Friday morning across the southern Great Lakes region and eastern corn-growing region, mainly east of I-55 in Illinois. No additional risks are predicted at this time as northwest flow is expected to remain dominant into the weekend.
