   The severe weather threat for Severe Thunderstorm Watch 512

   SUMMARY...Gusty winds and hail remain possible with storms as they
   propagate southeast this evening.

   DISCUSSION...Northwesterly mid-level flow is gradually increasing
   across the southern High Plains this evening as the Plains upper
   trough shifts east. Surface pressures are rising across the TX
   Panhandle and the primary zone of low-level confluence now stretches
   from central OK to south of LBB. A concentrated corridor of
   scattered strong/severe thunderstorms has evolved along this zone,
   and this convection should continue to propagate south-southeast
   into a modestly unstable air mass characterized by MLCAPE values on
   the order of 1500 J/kg. Wind gusts in excess of 60kt have been noted
   with the activity over the TX South Plains, and this should be the
   primary concern as the evening progresses; although, some marginally
   severe hail is also possible.
