Black Cutworm
Black cutworm migration risks return to the forecast tomorrow night into Friday mainly west of Lake Michigan and the I-57 corridor in Illinois as southerly winds develop ahead of low pressure and a cold front moving through the Plains states. This system is largely of northwest flow origin so the duration and strength of southerly winds precludes anything more than an isolated migration risk at this point. As this front moves east, the Low risks shift east with it, and are mainly focused over the southern Great Lakes and eastern corn-growing region Friday night into Saturday. Further out, Low risks have been introduced to the forecast on Sunday night into Monday mainly west of Lake Michigan as the next weather system develops in the Plains in what appears to be an increasingly more active weather pattern as we close out April and head into May. This system may warrant an increase in risk levels by next week, so stay tuned!
