A cold front will be dropping southeast over the next 24 hours and will likely provide a focus for showers/thunderstorms somewhere near the I-90 corridor in South Dakota, southern Minnesota, and into Wisconsin later today. As the front settles slowly southeast tonight into tomorrow, southwest winds feeding into the front and associated precipitation may lead to an isolated corn earworm moth flight risk tonight into tomorrow. Mid-south source regions are still favorable hosts for moths at the present time, so any flights further north should be more isolated in nature. Nonetheless, some new moths may arrive especially near and south of the I-80/90 corridors from Kansas and southeast Nebraska as far east as Indiana and western Ohio. By later in the week and weekend, forecast confidence decreases as a potential tropical system in the Gulf of Mexico may become a factor in influencing weather system development/progression in the corn-growing region. For now, Low migration risks are predicted mainly west of I-35 Saturday night into Sunday, but the forecast may change based on how this potential tropical system develops and more importantly, where it tracks. Stay tuned.
