A cold front is expected to push through much of the central and eastern corn-growing region by mid to late tomorrow. Ahead of the cold front, south to southwest winds along with at least scattered precipitation clusters may lead to some scattered corn earworm moth flights, primarily to the east of I-35. Moderate risks are predicted from east of Des Moines, Iowa to Rochester, Minnesota into Wisconsin, central and northern Illinois, northern Indiana, northern Ohio, central and southern lower Michigan, and far southwest Ontario, Canada this evening into midday tomorrow. Low risks extend east into southern Ontario, Canada and eastern reaches of the corn-growing region. No migration risk is predicted for much of the weekend as the front settles south and northwest flow dominates for a brief time across much of the region. Low risks return to the forecast by Sunday night into Monday morning across the Plains and then expand north into the I-94 corridor in eastern North Dakota southeast into central Minnesota and Wisconsin, and east into Illinois. Growers located in or near the Moderate risk area should monitor traps closely over the next several days as well as growers further west that may have experienced a flight overnight last night in the upper Midwest.
