Alert Details

Black cutworm migration risks re-enter the forecast as early as tomorrow night into Sunday as a rather complex weather pattern begins to unfold across the corn-growing region especially heading into next week. Southerly winds are likely to develop in the Plains and at least western corn-growing region by tomorrow, and Low migration risks are in the forecast mainly west of Lake Michigan and the I-55 corridor in Illinois. Low risks are then in the forecast on a nightly basis through at least next Tuesday/Wednesday as a persistent corridor of south to southwest winds and rather warm to hot temperatures (for this time of year) set up from the eastern Plains into the southern Great Lakes and eastern corn-growing region. For now, only Low risks are in the forecast mainly east of a line from near Wichita, Kansas to Minneapolis, Minnesota and then on east to near the I-75 corridor. Some adjustments and potential risk upgrades are possible early next week so stay tuned.
