Low corn earworm migration risks return to the forecast at the end of this week and into the early part of next weekend as a corridor of south to southwest winds develops in the Plains states ahead of a cold front. Low risks are predicted mainly west of I-35 Thursday night into Friday and then as far east as the I-39/US 51 corridor in Wisconsin and Illinois Friday night into Saturday. There may be some isolated moth flights into remaining processing and fresh-market fields at that time.
