Alert Details

Corn earworm flights, at least on an isolated basis, will remain possible over the next 24 hours or so as a cold front moves southeast through the corn-growing region. Hot temperatures southeast of the front along with at least light southwest winds may allow some isolated moth flights from Texas and Oklahoma northeast into Kansas, Missouri, eastern Nebraska, Iowa, southeast Minnesota, southern Wisconsin, and Illinois tonight into tomorrow morning. The overall pattern is favorable for moth flights, but a Low risk forecast was maintained given less than favorable source region and largely weaker wind fields further up into the atmosphere. Still, we caution growers that if your crops are at a susceptible stage to damage, monitoring traps and scouting fields will be important. Little to no additional migration risk is predicted after tomorrow heading into early next week as northwest flow is expected to dominate the picture once again.
