Corn earworm migration risks are expected to remain in the low category for the next five days as south to southwest wind flow is not expected to be particularly strong on any given day despite a somewhat active weather pattern across much of the corn-growing region. Low pressure will continue to develop across the central/southern Plains and eventually spread east northeast into the central and eastern corn-growing region and Great Lakes states. Southerly winds will be focused to the immediate east of the low and due to a lack of a stronger high pressure to the east, wind speeds will be kept in check. As a result, only Low corn earworm migration risks are predicted tonight into Thursday morning across portions of eastern Kansas, southeast Nebraska, southwest Iowa, and western/central Missouri with the risk spreading into the eastern Midwest and southern Great Lakes region by tomorrow night and Friday morning. The risk finally spreads into the far eastern corn-growing region and southwest Ontario, Canada by Friday night into Saturday morning as the low pressure system moves out. Already by late in the weekend, enough southerly wind flow in advance of the next low pressure system developing in the Plains warrants a Low risk mainly across portions of Kansas, Missouri, southern Nebraska, and southwest Iowa.
