The weather pattern is predicted to become more active as we head into late week and over the weekend, with no less than two weather systems expected to affect the corn-growing region. Heat and humidity, along with an increasing south wind, may lead to some isolated to even scattered corn earworm moth flights in the next week. Low migration risks are in place beginning tomorrow night and lasting into Friday morning mainly from eastern Nebraska into Illinois and points north into Iowa, Minnesota, and Wisconsin, as the first low pressure system and attendant cold front move through. Southerly winds in advance of the front along with precipitation near the front may lead to some isolated moth flights. Low risks then continue east of the Mississippi River Friday night into Saturday morning with the risk focusing back to the west of Lake Michigan already ahead of the next system Saturday night into Sunday, and as far east as southern lower Michigan and Indiana Sunday night into Monday. It is conceivable that an increase in the risk could occur in subsequent forecasts so please stay tuned. Growers with crops at susceptible stages to corn earworm damage should remain on alert as additional moths may appear in the next week given a favorable weather pattern for migration.
