A much more active weather pattern is expected to take hold across much of the corn-growing region for the rest of the month, with both heat/humidity and precipitation chances increasing for most areas. The resultant corn earworm migration risks will also increase as south to southwest winds will become more commonplace and could become gusty at times. Low migration risks are predicted to the east of a weak cool front tonight into tomorrow especially from Kansas, eastern Nebraska, and southeast Minnesota and points eastward as far as into the I-75 corridor. The Low risk then shifts east to mainly along/east of I-35 tomorrow night into Wednesday morning, and the focuses east of I-57 in eastern Illinois by Wednesday night into Thursday morning. Any break in the risk will be short-lived, however, as a stout heat ridge/dome begins to take shape already by Friday across the Plains and this will expand further east into the corn-growing region by the weekend. Low migration risks on increasing southerly winds right out of source regions in Texas will focus along/west of I-57 and Lake Michigan by later Friday into Saturday. Growers with more advanced garden or fresh-market crops may be at risk of seeing some early localized flights especially by this upcoming weekend and into next week as most field crops are still too early in their growth to be of concern at this time, so the earlier-maturing crops will be attractive hosts to those moths that do fly north.
