Alert Details

Low corn earworm migration risks are in the forecast mainly across portions of eastern Kansas, southeast Nebraska, far southern Iowa, Missouri, central and southern Illinois, and southwest Indiana for Thursday night into Friday morning as south to southwest winds in advance of a weak area of low pressure moves through the region. Primarily isolated moth flights are possible into this region given the expected weak wind speeds. The Low risk area shifts southeast into the southeastern Midwest from southwest Missouri northeast into southern Michigan for Friday night into Saturday morning. The weather pattern is predicted to stay in a northwest to southeast configuration for the balance of the next week or so, and the result will be a continuation of progressive low pressure systems moving from the northern Rockies into the High Plains and eventually through the upper Midwest. The next weather system should begin moving into the Plains states by late in the weekend, and a Low migration risk is predicted for fields mainly west of the Mississippi River and south of US 14 in Minnesota and South Dakota by Sunday night into Monday morning.
