Alert Details

A more active weather pattern is expected over at least parts of the corn-growing region for the week ahead. As a result, black cutworm migration risks are in the forecast nightly into next weekend as a couple of weather systems may produce favorable weather conditions for migration north from southern source regions. Low risks are predicted tonight into tomorrow morning mainly across the Plains into western Iowa and southwest Minnesota as low pressure organizes in the High Plains and southerly winds return to its east. Any flights should be more isolated in nature given the source region in west Texas and Oklahoma. Low risks continue tomorrow night into Wednesday morning mainly west of I-57 in Illinois and Lake Michigan as the entire system and weather setup moves to the east. Finally, by later in the week, Low risks focus mainly across the southern Great Lakes into the eastern corn-growing region Wednesday night into Thursday morning with Low risks returning to much of the corn-growing region, especially central and southern areas, by late week into next weekend in response to the next weather system developing in the central Plains. This late week/weekend system will have the potential for an increase in risk levels so please stay tuned this week for updates.
