Corn Earworm
An organizing area of low pressure and attendant cold front will slowly move southeast through the corn-growing region over the next several days. There are indications that this front may not push southeast of the region until early-mid next week, so a rather prolonged period of south to southwest winds is anticipated which may bring some isolated corn earworm moths into the corn-growing region. Low risks mainly focus west of Lake Michigan and into Illinois through Friday and Saturday, but do eventually expand east into the southern Great Lakes and eastern corn-growing regions by Saturday and into Sunday as high pressure drifts off to the southeast. Wind speeds will decrease from what they have been the past few days across the Plains states, but the source region will become more favorable across portions of the mid-south where corn earworm populations are high in some areas and continue to build. The primary concern at this point is not with field corn but with fresh market/vegetable/garden growers who may have host plants at susceptible stages to damage from any new flights.
