Alert Details

Isolated corn earworm moth flights will be possible beginning tomorrow night mainly along and west of I-35 as low pressure develops in the High Plains and as high pressure begins to shift east across the corn-growing region, allowing south to southwest winds to commence. Moving into the weekend, a very warm to hot weather regime is likely especially across the central and southern corn-growing region with an increase in south to southwest winds to the southeast of a deepening low pressure system across the Dakotas. Low corn earworm migration risks will remain in place mainly southeast of a line from near Goodland, Kansas northeast into southeastern Minnesota and points east to near I-75 in southeast Michigan and western Ohio. Low risks will remain in the forecast into early next week, as well, as the overall weather pattern is not predicted to change very much until mid-week when a cold front is expected to push southeast through the corn-growing region. Low risks will remain in place across a large portion of the corn-growing region until this front clears the region.
