A largely northwesterly flow weather pattern is expected to dominate the corn-growing region weather pattern for the next week or so. For purposes of black cutworm migration risks, this pattern limits the overall moth flight risk but any stronger weather systems moving quickly through the flow may result in mainly isolated flights. Such is the case this week, with a potentially potent but quick-moving system late week and into next weekend. Southerly winds are expected to increase by Thursday into Friday mainly across western and central portions of the corn-growing region, with a cold front then sweeping east Friday into Saturday. Low risks are in place along/west of Lake Michigan Thursday night into Friday, and then risks focus mainly across the southern Great Lakes and eastern corn-growing region Friday night into Saturday. Growers are encouraged to continue to monitor traps as some new flights may have occurred in the past week, and also for earlier planted corn that has now emerged, larvae scouting should continue especially in central and eastern portions of the corn-growing region where moth flights were heavier and/or more frequent last month.
