Alert Details

Another fairly potent low pressure system will impact much of the corn-growing region over the next few days before a cool-down by mid-late week and possibly beyond limits the overall black cutworm migration risk for a while. Before this system departs, however, Low migration risks on gusty southerly winds will continue tonight into tomorrow for areas from eastern Kansas, Missouri, and western Kentucky north as far as Minnesota, Wisconsin, and southwestern lower Michigan. The somewhat short duration of southerly winds in this area limits the overall risk, but it is possible that some scattered moth flights may occur in the most concentrated southerly wind areas or where a lack of precipitation does not limit flights. Low risks continue tomorrow night into Wednesday mainly east of the I-55 corridor from southeast Missouri and Illinois and points east as a cold front moves to the east. Northwest flow and cooler temperatures lock in after that and continue through the upcoming weekend. Growers should continue monitoring traps, scouting fields, and also continue heat unit accumulation calculations from previous flights that occurred in some areas in April.
