Alert Details

An active weather pattern across especially the southeastern half to three-quarters of the corn-growing region may lead to the opportunity for some isolated corn earworm moth flights in the next week. South to southwest winds are expected to focus to the east of a decaying low pressure system across the mid-upper Mississippi River valley tonight into tomorrow, with Low risks predicted generally east of the I-57 corridor in far eastern Illinois, Indiana, Kentucky, Ohio, lower Michigan, and into southern Ontario, Canada. Low risks then shift back into Kansas and Nebraska as the next weather system begins developing in the far western Plains states tomorrow into Wednesday. This Low risk then shifts east with a cold front southwest of the low pressure by late week, with Low risks focusing generally along/south of a line from southwest Kansas to near Chicago and points east into the southern Great Lakes region. The overall setup and crop stage is not favorable for widespread flights at this time, but growers with crops at susceptible stages to damage right now are encouraged to continue trapping efforts and scout fields.
