   Concerning...Severe Thunderstorm Watch 472...

   The severe weather threat for Severe Thunderstorm Watch 472
   continues.

   SUMMARY...The severe-wind threat may increase into early evening.
   Isolated hail also remains possible.

   DISCUSSION...Scattered thunderstorms are ongoing late this afternoon
   across parts of the central and northern High Plains. Some recent
   increase in radar-estimated hail sizes has been noted within WW 472
   across southeast WY and northeast CO, and also north of WW 472 into
   northeast WY. MLCAPE of 1000-1500 J/kg and moderate deep-layer shear
   will continue to support storm organization and isolated to widely
   scattered supercells capable of large hail and localized severe
   gusts through the remainder of the afternoon. 

   With time, increasing storm coverage and related outflow within the
   relatively well-mixed environment is expected to lead to an
   increasing severe-wind threat as storms move eastward across
   northeast CO and the NE Panhandle. While this upscale growth may
   only become modestly organized, the favorable thermodynamic
   environment could support one or more swaths of 65-80 mph gusts into
   this evening.
