A persistent quasi-stationary pulsing overshooting top was evident in both the Visible and Infrared imagery, and cloud-top infrared brightness temperatures were as cold as -80\u00baC at times — judging from 00 UTC Amarillo rawinsonde data<\/strong><\/a>, this represented an altitude of around 13 km. In addition, the presence of north-to-south oriented stable wave clouds in the Visible imagery marked the western edge of a residual convective outflow boundary from the previous evening.<\/p>\n

The storm also exhibited very prominent Enhanced-V<\/strong><\/a> and Above-Anvil Cirrus Plume<\/strong><\/a> signatures — a toggle between 0015 UTC Visible<\/strong><\/a> and Infrared<\/strong><\/a> images (below)<\/strong><\/em> illustrated these two signatures.<\/p>\n
