A rather fast, progressive northwest flow weather pattern is expected to continue to dominate the corn-growing region weather pattern in the next week or so. As a result, corn earworm migration risks are tied to cold front passages but overall rather Low in nature and short in duration given only brief periods of good southerly wind flow. A couple of risks are predicted in the next five days, the first being overnight tonight into tomorrow mainly from southern Missouri east northeast as far as Ohio – best chances are likely over Kentucky but still rain/thunderstorms may limit the overall risk. Low risks then return to the forecast Friday night into Saturday especially from southeast Kansas as far east as Kentucky northeast into the southern Great Lakes as a corridor of south to southwest winds sets up ahead of the next cold front. Even though risks are generally Low during this period, growers are still encouraged to monitor traps and scout fields as some isolated to localized flights can still occur.
