Corn Earworm
A more zonal or slightly northwest to southeast weather flow pattern is predicted for at least the next few days before the pattern shifts back to the west and southwest. With a westerly or northwesterly flow predicted for the next few days, no corn earworm migration risks are predicted as wind flow is not expected to be favorable for any migration. By Wednesday night into Thursday, a return to southerly flow is predicted mainly across Kansas, Nebraska, southern South Dakota, western Iowa, and western Missouri as a low pressure area organizes and as high pressure remains across the southern United States. A cool front is predicted to push southeast through the corn-growing region by late in the week, and Low risks are extended as far north as Minnesota and Wisconsin by Thursday night into Friday and then remain focused across Kansas and Nebraska by late week. While no larger scale flights are anticipated this week, some isolated flights could certainly occur especially west of Lake Michigan this week.
