Alert Details

Low corn earworm migration risks remain in the forecast tonight into tomorrow morning primarily across the southwestern portion of the corn-growing region. A warm front is expected to provide the focus for scattered showers and thunderstorms from Nebraska and northern Kansas east into Iowa and Missouri later today into tonight, and this front also serves as the dividing line between somewhat weak southerly winds to the south and lighter, more easterly or northerly winds to the north. Any insect migration should focus near and south of this boundary. With high pressure still holding firm further east, no other risks are in place other than mainly south of I-80 in Nebraska and Iowa and west of I-35 through central Iowa into western Missouri. A cold front is predicted to pass through the corn-growing region this weekend and early next week. Wind flow to the southeast of this front, however, is expected to be from the southwest and somewhat light in nature, so no risks are being issued at this time.
