Signs of autumn’s approach are in the weather forecast in the next 10 days with widely varying conditions. At the start of the period, northerly winds and cooler temperatures will be common which will keep any corn earworm migration possibilities non-existent through much of the weekend. By late in the weekend, however, southerly winds in a fast and progressive weather pattern will already be returning to the Plains and western Midwest as the next low pressure strengthens across the high Plains and southern Canada. Low migration risks are back in the forecast initially west of Lake Michigan and I-55 Sunday night into Monday, with the risk extending east into lower Michigan and Indiana Monday night into Tuesday. Growers, especially those in the fresh-market and processing industries, should be advised that some isolated to potentially scattered corn earworm moth flights may occur next week as a pretty windy system is expected and additional risks are likely as we move into next week.
