The weather pattern is expected to turn more active mid-late week as the overall flow transitions from northwesterly to zonal or even southwesterly ahead of the next developing low pressure system in the Plains states. With high pressure shifting to the east, southerly flow will have an opportunity to return to much of the corn-growing region at some point this week. The result will be virtually all areas will have a black cutworm migration risk this week, with elevated risks focused across the Great Lakes and eastern corn-growing region by late week. Low risks are already in the forecast west of I-35 by tomorrow night into Wednesday as southerly winds increase in this area. Low risks then focus from Kansas, Missouri, and Illinois northeast as far as Minnesota, Wisconsin, and into the southern Great Lakes area Wednesday night into Thursday, and then Moderate risks are predicted across Indiana, Ohio, southeast lower Michigan, and southern Ontario, Canada as a cold front moves southeast by Thursday night into Friday. Growers with newly-emerged corn are encouraged to scout fields as some flights that occurred especially in early April could potentially be producing larvae that may affect corn at this time.
