Alert Details

An active weather pattern is predicted to continue across at least a portion of the corn-growing region into next week. A low pressure system and associated cold front is organizing in the Plains states and will push southeast into the heart of the corn-growing region by tomorrow night before stalling out. Ahead of the front, southerly winds may pose an isolated corn earworm migration risk to fields mainly west of I-35 and south of I-90 tonight into tomorrow morning, or from Kansas and western Missouri north into South Dakota and southwest Minnesota. As the front moves southeast, precipitation along and ahead of the front may pose a continued isolated migration risk mainly south of a line from Wichita, Kansas to near Chicago, Illinois tomorrow night into Sunday morning. Low risks remain in the forecast next week as the front is predicted to remain largely in place somewhere near the US 34 or I-80 corridor from southern Nebraska into Iowa and Illinois with periodic shower and thunderstorm clusters near the front and southerly winds feeding north to its south. Growers in the Low risk area should be on the alert for the possibility of isolated moth flights as we move into early next week.
