Alert Details

Low corn earworm migration risks are in the forecast tonight into tomorrow morning especially across southeast Missouri, southern Illinois, southwest Indiana, and western Kentucky as low pressure moves east across Missouri and eventually into the Ohio River valley. Somewhat weak southerly winds to the southeast of the low pressure may result in shorter distance corn earworm migration from source regions near I-40 in Arkansas and western Tennessee. Trap counts in these areas are increasing which indicates an active moth population is present. Growers should be on the alert for the potential of some isolated increases in moth captures especially across the Missouri bootheel growing area and into adjacent sections of Illinois, Kentucky, and Indiana. Northwest flow is predicted to dominate the weather into next week, but a cold front should move through much of the corn-growing region early next week. Southerly winds are predicted to increase to the east of the front late in the weekend and early next week, so Low risks are in place as far north as I-90 and east into eastern Iowa and Missouri Sunday night into Monday morning.
