Alert Details

An upper level low pressure system will continue to move east across the mid-south region the rest of today into tomorrow. While upper level low pressure systems are not the most ideal for larger scale corn earworm migration events, a combination of a favorable source region and focused southerly flow to the east of the low pressure does warrant a Low migration risk tonight into tomorrow morning for portions of Kentucky, Indiana, and Ohio. Only isolated flights are predicted at this time given less than favorable conditions. Northwest to southeast flow is expected to dominate the weather across the corn growing region through the end of the week so no risk is in place until Friday night into Saturday morning. By the weekend, Low migration risks are back in the picture especially across the western corn-growing region as the next low pressure system takes shape in the High Plains. Risks are initially in the Plains but do spread east to near the Mississippi River by Saturday night and Sunday morning as southerly winds increase and move east.
