A complex weather pattern is expected the next few days as several rounds of showers/thunderstorms are likely to impact at least the southeastern half to two-thirds of the corn-growing region ahead of a strong cold front. South to southwest winds will increase east of the front today and continue into tomorrow, as well, and these winds may lead to isolated corn earworm migration risks tonight into tomorrow, especially, from eastern Kansas into Missouri, eastern Iowa, southern Wisconsin, and points east and southeast through midday tomorrow. Once the front moves through the eastern areas later Thursday or very early Friday, little to no additional migration risks are anticipated as cooler weather on northerly winds are likely to settle in through early next week. Growers should continue trapping efforts as even though most crops are not at susceptible stages to corn earworm damage right now, new generations from these arriving moths may cause issues later on in the growing season. Some fresh market crops will start to become vulnerable in just a matter of a week or two (sweet corn, notably) especially in areas where this crop was planted earlier.
