A continued active weather pattern is expected through the balance of the forecasting period. South to southwest winds are expected to be persistent from source regions in Texas, Oklahoma, Arkansas, and Louisiana right into the heart of the corn-growing region for the next several days. While some variations in the location of the strongest wind corridors are likely, the overall theme will be the chance for isolated corn earworm flights to the north. The risk area tonight into tomorrow morning is centered slightly further south than last night, mainly across Kansas, Missouri, Iowa, Illinois, and Indiana. The risk area shifts east Thursday night into Friday morning into the eastern Midwest and southern Great Lakes region as a cold front pushes slowly southeast. By the extended period (late week into early next week), a new area of low pressure is likely to develop across the Plains states and a warm front should serve as the dividing line between cooler air to the north and warmer air to the south (roughly between I-70 and I-80). Low risks continue mainly west of the Illinois/Indiana border and south of I-80 during this time.
