Alert Details

A quick-moving low pressure system is predicted to move through the corn-growing region in the next several days. With only a limited amount of time for south to southwest winds to blow north from active source regions in the mid-south, only Low risks are predicted primarily along and east of a cold front trailing to the south of the low pressure system. Low risks are in place tonight into tomorrow morning mainly across Nebraska, Kansas, and far western Iowa. The risk spreads east into Iowa, southern Minnesota, Missouri, southern Wisconsin, and Illinois by Friday night and Saturday, and finally across the southern Great Lakes and eastern Midwest by Saturday night into Sunday. There is the potential for isolated moth flights during this time, but larger scale flights are not currently anticipated. Growers should continue monitoring fields at susceptible stages to damage as larvae from previous moth flights this summer may now be present.
