Alert Details

An active weather week is expected for much of the Corn Belt this week. A cold front is predicted to slowly push southeast through the Plains and into the Midwest through the week and will likely stall out by late week from Iowa-Missouri east into Illinois, Indiana, and Ohio. A persistent south to southwest wind regime is likely to stay in place through the entire five day period and expected periodic precipitation events may serve as potential drop zones near the front. With increased moth counts in mid-south traps recently reported, corn earworm migration risks are increased into the Moderate category from Tuesday noon through Thursday noon across a portion of the Plains into the central and southern Corn Belt, or from Oklahoma and Kansas northeast into southeast Nebraska, Missouri, Iowa, Illinois, and even as far east as northwest Indiana and southwest Michigan by Thursday morning. Outside of the Moderate risk areas, Low risks envelop much of the central and southern Corn Belt through the next five days as the front remains in place.
