Alert Details

Low corn earworm migration risks return to the forecast late in the weekend and early next week as a weak cold front moves through the corn-growing region. South to southwest winds will increase to the east of the cold front but are expected to be rather weak overall so only Low risks are predicted at this time. The primary risk area Sunday night into Monday morning is generally west of a line from Wichita, Kansas to Albert Lea, Minnesota and south of I-90. The risk area shifts east Monday night and includes mainly the central corn-growing region from eastern Nebraska into northwest Indiana and southwest Michigan and as far north as eastern Minnesota and Wisconsin. As the weather pattern shifts back to northwesterly flow by the middle of next week, no risk of corn earworm migration is predicted at that time.
