Low pressure will continue to organize across the Plains states today while high pressure drifts slowly east into the eastern corn-growing region and southern Great Lakes. Southerly flow is expected to increase across the Plains states into the western corn-growing region, especially along and west of the Mississippi River. Low black cutworm migration risks are in place tonight into tomorrow morning from Nebraska and Iowa north into the Dakotas, Minnesota, and far western Wisconsin. As a cold front trailing to the south of the low pressure system begins to push southeast tomorrow into Saturday, the Low risk shifts east as well, especially in response to high pressure moving into the eastern United States. Southerly flow is not expected to be really strong, so only Low risks are predicted mainly from central Nebraska and eastern South Dakota east into southern lower Michigan and western Ohio. No additional risks are predicted late in the weekend and early next week as wind flow becomes unfavorable for migration.
