Alert Details

Low corn earworm migration risks are in the forecast both tonight and tomorrow night as south to southwest winds increase ahead of a southeastward-advancing cold front early-mid week this week. The overall weather pattern is northwest-flow dominant so overall risks are low due to the limited long-duration south to southwest flow. The Low risk area tonight into tomorrow morning focuses mainly west of I-35 across northern Kansas and northwest Missouri northeast into eastern South Dakota and Minnesota. The low risk area shifts east tomorrow night into Wednesday morning and is focused mainly east of a Goodland, Kansas to St. Cloud, Minnesota to Lake Michigan and southward into Illinois. No additional risks are predicted after Wednesday morning, but growers all across the corn-growing region with crops at susceptible stages to corn earworm damage should continue to monitor traps and scout fields as some moth flights may have occurred late last week and into this past weekend.
