Alert Details

A strong cold front is likely to move through the central and east corn-growing region over the next 24-36 hours. Ahead of the front, south to southwest winds along with at least scattered to potentially widespread showers and thunderstorms are expected. A combination of a lack of favorable hosts across mid-south and southern corn-growing region, near full moon, a prolonged period of south to southwest winds, and crops still in a susceptible stage to damage at least on a scattered basis has led to a continued Moderate risk across portions of Illinois, southeast Wisconsin, Indiana, Ohio, and lower Michigan tonight into tomorrow morning. A brief break in the risk is anticipated tomorrow night, but Low risks then return from Kansas and Missouri northeast into areas both west of and into the southern Great Lakes region Saturday night into Sunday with Low risks also in the forecast on Monday night into Tuesday mainly west of I-35 as the next southerly wind event begins ahead of the next cold front late next week or weekend. Growers with crops still at susceptible stages to damage, including but not limited to, fresh market and processing growers and late or re-plant field corn growers as well as vegetable crops should continue to monitor traps and scout fields until the crop is past critical growth stages.
