A cold front will be pushing southeast through much of the corn-growing region by late this week. Ahead of this front, south to southwest winds along with heat and humidity will be on the increase for the next 2-3 days, and these winds may lead to isolated or even scattered corn earworm moth flights especially along and just east of the frontal boundary. As southerly winds increase across the Plains tonight, Low migration risks are in place for the potential of isolated moth flights. Moderate risks are predicted tomorrow night into Thursday morning from Nebraska and Iowa north into eastern South Dakota, southeast North Dakota, Minnesota, and western Wisconsin as a combination of stronger south to southwest winds and the potential for precipitation increases. Low risks extend as far as Lake Michigan and I-55 in Illinois. Moderate risks continue Thursday night into Friday morning from central and eastern Iowa into northern Illinois, far southeast Minnesota, and central/southern Wisconsin as the front pushes to the southeast. Only Low risks are predicted mainly east of I-57 in far eastern Illinois Friday night into Saturday as wind flow weakens by that time. Growers with crops at susceptible stages to damage should continue checking traps and scout for potential larvae and/or damage.
