The merged AzShear product has done a solid job keeping up with low & mid level rotation tracks so far this afternoon in the Texas panhandle. Most of the storms over the last hour have exhibited weak low level rotation but much stronger mid level rotation. The merged AzShear product showcases it well with much hotter values on the mid-level product compared to low level. This also matches well with the threats observed so far with several reports of large hail, but any tornado threat has yet to materialize.
