Alert Details

A rather deep area of low pressure, especially for the summer months, is expected to track from the northern corn-growing region slowly into the southern Great Lakes region over the next 36-48 hours. A cold front trailing south of the low will also push somewhat slowly to the east, with at least modest southerly flow to its east. Low corn earworm migration risks are predicted tonight into tomorrow morning mainly east of the Mississippi River especially across the southern Great Lakes and eastern corn-growing regions. Low risks continue in the forecast tomorrow night into Saturday morning as southerly flow is expected to remain in place mainly across portions of Indiana, Ohio, southeast lower Michigan, and into southern Ontario, Canada prior to the cold front moving through. No additional risks are predicted thereafter as northwest flow is likely to dominate the weather pattern through at least the middle of next week.
