Alert Details

An active weather week is expected and with corn and other vegetable/fresh market crops further north in the corn-growing region nearing or in vulnerable stages to damage from corn earworm, migration risks are in the forecast until a cold front clears the corn-growing region this weekend or early next week. Low risks are predicted tomorrow night into Thursday morning from Kansas and Missouri northeast as far as Minnesota and Wisconsin as southerly winds increase to the south of a cold front trailing from low pressure in southern Canada. Low risks then continue in the forecast mainly along and south of I-90 through the extended period, but with lower confidence as we get into the weekend. There are some discrepancies on exactly when the cold front will pass, but Low risks are in place to account for potential mainly isolated moth flights. Mid-south and southern source region crops are still attractive to any potential migrating moth candidates at this point so only isolated flights are expected at this time.
