Alert Details

A low corn earworm migration risk is predicted for fields south of I-80 and west of US 65 tonight as a low pressure area develops in the High Plains and southerly winds blow north from source regions primarily in Texas. The risk persists into Tuesday night and Wednesday morning as well for fields mainly in Nebraska, central and eastern Kansas, Missouri, Iowa, and much of Illinois as south to southwest winds expands further east. A low risk also returns by late this week and into next weekend initially across Kansas and Nebraska but then expanding further north and east as southerly winds increase. The risk area remains primarily west of the Mississippi River and south of I-90 by late week.
