Alert Details

No corn earworm migration risks are predicted across the corn-growing region for the next two nights, but risks do return by Saturday night into Sunday and into early next week as the next weather system moves quickly through the Midwest and Great Lakes region. A period of stronger southerly winds is expected across portions of the Plains and western Midwest by Saturday night and with precipitation also possible in this same area, a Moderate migration risk has been issued for portions of Kansas, far northwest Missouri, central/eastern Nebraska, far western Iowa, extreme southwest Minnesota, and southeast South Dakota. Low risks extend to near the Mississippi River and north to near the North/South Dakota border into central Minnesota during this time. As the low pressure center moves east, it is expected to decrease in strength so southerly winds to its east are not predicted to be as strong. Therefore, only Low risks are predicted Sunday night mainly across Missouri, Iowa, Illinois, and into portions of Michigan, Indiana, western Ohio, and Kentucky. Finally, by Monday night, fields from eastern Ohio into Pennsylvania and points to the southwest may see isolated flights and a Low risk is in place. Growers across much of the Midwest and Great Lakes region are urged to monitor their fields for corn earworm activity as scattered locations have seen increased trap counts since the moth flight last weekend.
