Alert Details

A cool front is expected to push southeast from the Plains states into the northern and western corn-growing region later today and eventually through much of the northern and central corn-growing region by mid-late week. With high pressure centered over the southeast United States, a corridor of southerly winds is expected east of the front and may lead to some isolated corn earworm moth flights later today into tomorrow. Low risks are in place from Kansas and Missouri as far north as eastern South Dakota, Minnesota, and Wisconsin. While the majority of field crops in this region are not at a susceptible stage to corn earworm damage at this point, there may be some other hosts and vegetable crops that may be, and these plants should be monitored. Otherwise, wind flow is not expected to be favorable for migration the rest of this week into next weekend so little to no risk is in the forecast after tomorrow.
