A long-lived, prolific above anvil cirrus plume (AACP) generating storm produced large hail and heavy rainfall as it tracked southeast along the Sangre de Cristo mountains in south-central Colorado on Tuesday. The largest hail report from the storm was 1.75″, 12 miles south of Westcliffe. The storm tracked over two burn scars, leading to flash flooding. The AACP signature indicates a particularly strong updraft and increased likelihood of a severe storm.
