Moderate deep-layer shear near the instability axis should support a severe threat during the afternoon and evening. A severe threat could develop during the day but would remain relatively isolated due to a lack of storm coverage. An isolated severe threat could also develop across parts of the central and northern High Plains during the afternoon. It appears that an isolated severe threat could develop along and near the instability axis each afternoon and evening.
