Alert Details

A very warm to hot weather pattern is predicted for especially the central and southern corn-growing region this weekend and into next week. South to southwest winds are expected to be rather gusty in between departing high pressure to the east and a deepening area of low pressure across the Plains states. With little to move the low pressure system, the overall weather theme should change little into early next week. Some isolated corn earworm moth flights will be possible on these gusty south to southwest winds throughout the period. Tonight into tomorrow morning, the primary risk should remain along and west of I-35 in the Plains states and western corn-growing region, but the overall risk does expand east thereafter into the southern Great Lakes region and eastern corn-growing region, as well, and lasts into at least Tuesday night into Wednesday morning. While there is no real threat to field crops at this time, early-season flights may lead to greater pressure later in the summer. Additionally, vegetable and fresh market growers should monitor traps and their fields/gardens for potential new moths in the next week.
