Alert Details

After a week of predominantly southwest to southerly flow and the potential for corn earworm flights on a near daily basis, the weather pattern has shifted to northwest flow across much of the corn-growing region. As a result, corn earworm migration risks are limited to primarily the Plains states this week. No risk is predicted overnight tonight into tomorrow morning, but Low risks do return to Kansas, Nebraska, southern South Dakota, southwest Minnesota, western Iowa, and western Missouri tomorrow night into Wednesday morning as southerly flow increases to the east of a developing low pressure system. Low risks then remain in the forecast across the Plains states from Kansas north into South Dakota for the balance of the week and into next weekend. Eventually, migration risks are predicted to expand further east into the corn-growing region, but not likely until next weekend or into the next week as it appears right now. Growers, however, are advised to check traps and continue scouting this week as some flights may have occurred in scattered areas from late last week into this past weekend.
