Alert Details

Rather weak wind flow to begin the week precludes any corn earworm migration risks. By later in the week and weekend, however, Low risks have been introduced to the forecast mainly west of I-35 as southerly wind flow increases ahead of a developing low pressure system in the far northern Plains or southern Canada. Low risks are predicted as early as Wednesday night into Thursday west of I-35, with the risk spreading east by Thursday night into Friday to near the Mississippi River. Low risks then expand east into portions of Wisconsin and Illinois by Friday night into Saturday but with less confidence in how a potential cold front may push southeast by that time.
