Alert Details

An active weather pattern is predicted for the rest of this week with another low pressure deepening across the western Plains states with a cold front trailing south of the low into portions of the central and southern Plains. As high pressure across the heart of the corn-growing region moves off to the east, south to southwest winds are likely to increase east of the front. There is a chance that some isolated corn earworm moth flights may occur tonight into tomorrow morning mainly west of I-55 in Illinois and also west of Lake Michigan, and generally along/south of the I-94 corridor from eastern North Dakota into central Minnesota. The cold front is likely to push further southeast tomorrow into tomorrow night, and should confine the Low risk to areas mainly along and east of I-35 in eastern Kansas, northwest Missouri, and into central Iowa and points east into Illinois, Indiana, Ohio, and into southern lower Michigan. Low risks continue in the forecast across the same general area Thursday night into Friday, but then the Low risk focuses across the eastern corn-growing region by Friday night into Saturday morning as the front finally gets a push to the southeast. Vegetable and fresh market growers are encouraged to monitor traps and scout fields closely as the greatest threat from any isolated moth flights this week should be with these crops.
