Low corn earworm migration risks are in the forecast on a nightly basis through the middle of next week as a fairly stagnant, late growing-season weather pattern takes hold across much of the corn-growing region. Southerly wind flow, while present, is expected to be mainly weak in nature so migration risks are kept in the Low category and also considering the time of year and majority of crop stages. Low risks are predicted tonight into tomorrow mainly west of Lake Michigan and I-57 in eastern Illinois, with the risk then spreading east to between I-35 and I-75 tomorrow night into Sunday as a weak cool front moves southeast but largely dissipates. By early next week, Low risks focus mainly west of the Great Lakes as a heat dome builds especially west of the Mississippi River. There is a possibility that a few nights may be upgraded to Moderate risks next week but enough uncertainty at this point to preclude higher risks.
