A cold front will be moving southeast through the corn-growing region today as low pressure deepens and tracks from the central Plains into the Great Lakes region. South to southwest winds are likely to the southeast of the cold front with precipitation likely developing along and east of the front, as well. The southwesterly winds are expected to originate in a favorable overwintering zone for black cutworm, so Moderate migration risks are in the forecast especially across Illinois east into Indiana with Low risks from roughly the I-35 corridor east into the I-75 corridor in Ohio. Once this system pushes through, a break in the migration risks is anticipated until late in the weekend or early next week when the next low pressure system develops in the Plains states. Low risks are back in the forecast across the eastern Plains and into Minnesota and Iowa by Sunday night into Monday in response to this potential weather system.
