Alert Details

An upper level low pressure system may pose a risk of some isolated corn earworm moth flights into portions of the eastern corn-growing region in the next 24 hours. Low risks are predicted from along and east of I-57 from southeast Missouri into eastern Illinois, northern Kentucky, Indiana, and Ohio. South to southwest winds may lead to some flights into the risk area but concerns over precipitation and overall less than optimal wind speeds may limit the overall risk. No migration risks are predicted tomorrow night into Wednesday morning, but Low risks do return to the Plains states by Wednesday night into Thursday morning as the next low pressure and cold front begin affecting the corn-growing region. Moderate risks are in the forecast across portions of Nebraska, southeast South Dakota, southern Minnesota, far western Wisconsin, and Iowa by Thursday night into Friday morning and across northeast Illinois, southeast Wisconsin, northwest Indiana, and far southwest lower Michigan on Friday night into Saturday morning as this cold front pushes to the southeast. Fresh-market and processing growers as well as any late planted field corn with fresh silks should continue to monitor traps closely and scout fields as flights have occurred across many portions of the upper Midwest in the last couple weeks. Also, please continue to monitor subsequent forecasts as the frontal timing later this week may need to be adjusted which would also slightly change the overall risk areas, as well.
