Alert Details

A quick-moving cold front is expected to bring a rather short period of south to southwest winds especially across the Plains states but potentially as far east as the I-35 corridor in Minnesota, Iowa, and northwest Missouri overnight tonight into tomorrow morning. Despite the short duration of favorable southerly winds, there could still be some isolated, perhaps shorter-distance corn earworm moth flights during this time until winds switch back to the northwest for the balance of the week and into much of the upcoming weekend. Low migration risks are predicted generally west of I-35 tonight into tomorrow morning to account for the potential isolated migration risk. Little to no additional risks are predicted after midday tomorrow, but additional risks are possible by early next week. Despite the lack of overall risks in the forecast, growers with crops still in a susceptible stage of damage should continue to monitor traps and scout fields as previous moth flights may have resulted in new generations in some fields.
