Corn earworm migration risks look limited to none until late this week when a cold front quickly moves southeast through the corn-growing region. A period of south to southwest winds is possible ahead of this front, especially from the southern Great Lakes region into the eastern corn-growing region. The forecast has a Low migration risk mainly along and east of I-55 in central Illinois Thursday night into Friday morning to account for this risk. If this front does slow down a little more, we may see enough support to raise migration risks across a portion of the eastern corn-growing region late this week but forecast confidence is not high enough at this point especially with a northwest flow pattern. No additional risks are in the forecast as northwest flow should dominate the weather otherwise.
