Alert Details

An active week of weather is predicted this week and into next weekend across a good portion of the corn-growing region. As a result, black cutworm migration risks are in the forecast with elevated risks across a portion of the Midwest tomorrow night into Wednesday morning. For tonight into tomorrow morning, a cold front will continue to push southeast through the heart of the corn-growing region. Additional showers and thunderstorms are likely to the southeast of the front, and a Low black cutworm migration risk is in the forecast especially for fields east of I-57, or from eastern Illinois into Indiana, Ohio, and Kentucky where southwest winds may continue to result in mainly isolated moth flights from the mid-south and southern United States regions. A Moderate black cutworm risk is predicted tomorrow night into Wednesday morning from Missouri and Illinois north into Iowa with Low risks from eastern Kansas into far eastern Illinois and north into Nebraska, Iowa, and northern Illinois as another deep area of low pressure moves across the Plains states. As a cold front pushes southeast ahead of the front, the main black cutworm risk is expected to focus across the southern and eastern corn-growing region by late week. Growers across especially the eastern two-thirds of the corn-growing region are urged to monitor for new black cutworm moths this week, especially where corn has been recently planted.
