Alert Details

Low pressure is expected to continue to develop and deepen initially across Colorado/Wyoming but by tomorrow move east into Kansas and Nebraska. High pressure will continue to drift into the eastern United States, so southerly winds will become more common and increase in speed across the Plains and into a good portion of the corn-growing region in the next few days. Subsequent black cutworm migration risks will follow, with Low risks across much of the corn-growing region west of Lake Michigan tonight into tomorrow and then from the eastern Plains states as far east as lower Michigan, Indiana, western Ohio, and Kentucky tomorrow night into Friday. Little, if any, risk is predicted by the weekend as the overall pattern breaks down and the parent low begins to dissipate. Growers are encouraged to regularly scout fields as many areas are reaching peak cutting dates as a result of heavy moth flights in early-mid April in some areas.
