A cold front is expected to push southeast through much of the corn-growing region over the next 24-48 hours. Ahead of the front, southerly winds are likely to continue and precipitation will also become more common, as well, and the combination of these two features may lead to scattered corn earworm moth flights especially along and east of I-55 in Illinois, Indiana, Ohio, southern lower Michigan, and also into southwest Ontario, Canada where a Moderate migration risk is in place tonight into tomorrow morning. Low risks extend back west into far eastern Iowa and also into southern Wisconsin and points east. A brief break in migration risks comes tomorrow night, but already by the end of the week and into next weekend, Low risks once again envelop much of the central and northern corn-growing region as an active holiday weekend weather pattern is anticipated. Next weekend’s setup does not look quite as favorable for widespread or heavier flights so only Low risks are in the forecast at this time, but it will be a time period that will be monitored closely.
