Alert Details

A strong spring storm system is likely to track through the heart of the corn-growing region this week, and will bring with it a fairly widespread black cutworm migration risk, as well. Strong southerly winds are anticipated to the east of the low pressure track, with Low risks already in place across Kansas, Nebraska, western Iowa, and western Missouri by tomorrow night into Wednesday. As the low pressure system moves into the Plains states and rapidly deepens Wednesday into Thursday, southerly winds are likely to become quite gusty further to the east, and a Moderate migration risk has already been issued for areas from eastern Kansas into Missouri, Iowa, Illinois, and far southern Wisconsin Wednesday night into Thursday. The Moderate risk then shifts east as a cold front sweeps across the Mississippi River later Thursday into Friday, with the risk area including far eastern Illinois, Indiana, northern Kentucky, Ohio, much of southern lower Michigan, and into far southwest Ontario, Canada. While there is little to no immediate threat from this expected flight given lack of newly-emerged crops, generations that develop from this flight may be a factor with newly-emerged corn come next month.
