Alert Details

Remnants of Tropical Storm Bill will continue to spread north into the southern portion of the corn-growing region. To the east of Bill, some southerly winds will occur and while the risk areas are rather focused, some isolated moth flights will be possible especially into eastern Kansas, southern Missouri, and southern Illinois tonight and then across southeast Missouri, southern Illinois, far southwest Indiana, and southwest Kentucky tomorrow night. Once Bill moves out, a cold front is predicted to push southeast through much of the corn-growing region before stalling out this weekend and into early next week. Low corn earworm migration risks are initially predicted across the Plains and western Midwest Friday night into Saturday, then from Kansas northeast into Illinois and Indiana Saturday night into Sunday. As the front stalls likely somewhere between I-70 and I-90, continued mainly weak to occasionally moderate southerly winds will feed into the front and may pose an isolated moth flight risk mainly along and south of I-80 to the west of I-65 early next week.
