The weather pattern across much of the corn-growing region is expected to continue to be very active over the next several weeks, with periodic weather systems moving through the area anywhere from 2-5 days apart. The result will be continued periodic associated black cutworm migration risks as these systems pass through. Low risks are in the forecast mainly along and south of I-80 tonight into tomorrow as a frontal boundary in between I-70 and I-80 remains in place. Southerly winds will continue south of this front but should not be overly strong. As the next in a long series of low pressure systems develops in the northern Rockies, southerly winds will once again increase in the Plains states and western corn-growing region by later Friday into Saturday. Low migration risks are already in place west of I-35 during this time. As the system deepens and high pressure remains anchored over the southeast United States, south to southwest winds will continue to increase and also expand eastward with time, and we now have a broad and pretty large area under a Moderate migration risk from Saturday night right into Tuesday of next week, with the risk initially found mainly west of the Mississippi River Saturday night into Sunday, but then spreading east into the Great Lakes region by late in the weekend and into next week. Growers should be monitoring traps closely for new flights as new generations from these current flights may impact newly-emerged corn next month.
