A strong cold front is predicted to push through the corn-growing region in the next 24-36 hours. To the east of the front, however, south to southwest winds will continue and may provide a continued threat for scattered corn earworm moth flights into especially the Great Lakes region and eastern Midwest later today into Tuesday morning. Moderate corn earworm migration risks are predicted for central and eastern Illinois, Indiana, Ohio, lower Michigan, and into southern Ontario, Canada through midday Tuesday with Low risks as far east as the Appalachian Mountains. Once the cold front pushes east, high pressure is expected to build in across the Plains states and winds will go northwesterly which will end any migration threats. A new low pressure system is predicted to begin developing in the Plains states late this week and into next weekend, and this will be the next migration threat as high pressure moves to the east and southerly winds commence in the Plains once again. Low risks are in place by Friday night into Saturday across portions of Kansas, Nebraska, southwest Iowa, and western Missouri at that time. Growers all across the corn-growing region are urged to monitor their fields and traps for signs of corn earworms as isolated to scattered flights have likely occurred in the past several days.
