Alert Details

A strong low pressure system will be developing across the Plains states this weekend before moving northeast through the corn-growing region by late in the weekend and early next week. Ahead of this system, south to southwest winds should provide an opportunity for at least an isolated but potentially scattered black cutworm migration event initially across the eastern Plains states and to the west of the Mississippi River tomorrow night into Sunday morning. Low risks are in place from Texas north into Kansas, Missouri, and southern Iowa during this time. By Sunday night into Monday, as a cold front begins to shift southeast through the corn-growing region, southwest winds from Texas and Louisiana will blow northeast into especially the eastern corn-growing region and could intensify. Given the favorable southwest wind flow and prospects for precipitation, Moderate black cutworm risks are in place from southeast Missouri and northwest Tennessee northeast into southeast Illinois, Kentucky, Indiana, and Ohio. Low risks extend to near the southern Great Lakes but mainly south of a Wichita, Kansas to Chicago line. Growers located in the Moderate risk area should pay close attention for signs of new cutworm moths by next week, and keep the flight date in mind for later this spring once corn is planted and emerging.
