Alert Details

A rather potent and deep area of low pressure is expected to move slowly southeast and churn over the eastern corn-growing region for the next day or so. Just to the east of a trailing cold front south of the low, some southerly winds along with precipitation are likely. For this reason, Low corn earworm migration risks are in place mainly along and east of the I-65/I-69 corridor in Indiana and southern lower Michigan tonight into tomorrow morning. Otherwise, no additional migration risks are in the forecast through mid-week next week as northwest flow dominates the weather pattern over much of the corn-growing region. Growers should continue to monitor traps and scout fields despite any risks in the forecast, especially if crops are at susceptible stages to earworm damage.
