Alert Details

A strong spring storm system is predicted to develop across the Plains and upper Midwest by this weekend and into early next week. Meanwhile, high pressure is expected to settle into the southern and southeastern United States. In between these two pressure centers, south to southwest winds are likely to blow from Texas north into portions of the Plains and southern corn-growing region by Saturday night into Sunday, and then into the eastern corn-growing region by Sunday night into Monday ahead of a cold front. Low black cutworm migration risks are in place from Texas north into Kansas, Missouri, and portions of southern Iowa Saturday night into Sunday morning. As the system deepens, southerly winds could increase by Sunday into Sunday night, and a Moderate migration risk has been issued especially for portions of Indiana, Ohio, southeast Illinois, Kentucky, southeast Missouri, far northwest Tennessee, and northeast Arkansas. Low risks continue from near the Mississippi River east to the Appalachians but mainly south of the I-80/90 corridor in Illinois, Indiana, and Ohio. While corn planting has yet to begin in many areas, these migratory moths from this next event may lay eggs which could hatch later this spring once corn has been planted and is emerging. Growers are urged to monitor traps for signs of new moths next week, especially if located in the Moderate risk area.
