Alert Details

A favorable weather setup for black cutworm migration is predicted over the next three days or so as high pressure settles into the eastern United States and low pressure develops and deepens across the northern Plains region. In between these two pressure centers, south winds will increase and become quite gusty in many areas which may lead to scattered moth flights. Low risks are in place tonight into tomorrow mainly along/west of the Mississippi River. Moderate risks are in the forecast across a pretty large area from Nebraska and South Dakota east as far as lower Michigan and Indiana tomorrow night into Saturday. Finally, as a cold front begins to move east and the parent low weakens, Moderate risks continue in the forecast Saturday night into Sunday mainly along/east of I-35 from Missouri and Iowa as far east as southwest Ontario, Canada and Ohio. Little to no risk is predicted early next week as northwesterly flow becomes dominant once again, but growers are encouraged to monitor traps especially if located in or near a Moderate risk area as at least some flights are likely over the next several days.
