A potent low pressure region is taking shape in the southern/central Plains states, and is likely to track east northeast into the corn-growing region by tomorrow and then off to the east by late week. Southerly winds are likely to increase ahead of this low pressure system, and could result in at least isolated black cutworm moth flights across a fairly broad area from central Kansas and Nebraska as far east as the Illinois/Indiana line and also as far north as southern Minnesota and Wisconsin tonight into tomorrow. The system is expected to deepen further tomorrow, so migration risks have been increased into the Moderate category especially in the warm sector ahead of the cold front across eastern Illinois, Indiana, western Ohio, and southern lower Michigan where scattered moth flights will be possible especially given the direct connection to source regions in the deep south. Little to no additional risk is predicted after Thursday, but these new flights may be cause for concern by later in the month and potentially into June, as well, given that planting progress across a large part of the corn-growing region is running behind average.
