   Valid 180100Z - 181200Z

   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM SOUTHWEST
   KANSAS INTO THE EASTERN TEXAS PANHANDLE AND SOUTH PLAINS...

   ...SUMMARY...
   A few strong to locally severe storms with gusty winds and marginal
   hail remain possible over the southern High Plains.

   ...Southwest KS into the TX Panhandle...
   Isolated strong cells currently exist near a surface trough
   extending from southwest KS into the eastern TX Panhandle and South
   Plains, within a low-level lapse rate plume. Weakly veering winds
   with height and deep-layer shear near 25 kt are aiding slow,
   southward-moving cells with periodic strong cores.

   Capping is forecast to remain relatively weak during the evening
   where low-level lapse rates are strongest, with northerly winds
   aloft aiding storm motions into parts of the South Plains. A
   marginal hail and wind risk may thus persist through at least 03Z,
   and perhaps a bit longer, within the narrow north-south plume of
   favorable theta-e.
