A low pressure system is predicted to move into the Plains as high pressure drifts into the eastern United States. South to southwest winds are expected to develop between the two pressure centers, and may pose an isolated corn earworm migration threat especially to the far southern Midwest where corn is further along in planting and emergence, and also where more opportunities for hosts are possible. Fields from south central into central Kansas, southern and central Missouri, and southwest Illinois are included in the risk overnight tonight into Thursday morning. If such a weather pattern was in place later in the summer especially during tassel or later, a much higher risk would be issued but given crop stage and time of year, only an awareness Low risk is being issued. No other risks are in place through the next five days.
