   Areas affected...Parts of central Oklahoma into western North Texas

   Concerning...Tornado Watch 86...

   Valid 020118Z - 020315Z

   The severe weather threat for Tornado Watch 86 continues.

   SUMMARY...The risk of damaging winds and a couple tornadoes
   continues across Tornado Watch #86.

   DISCUSSION...An MCS is tracking slowly eastward across western OK
   and western North TX, with embedded supercell structures on the
   southern portion of the line along/south of the Red River. Over the
   next couple hours, the risk of a couple tornadoes, damaging winds,
   and large hail should be maximized with the southern storms
   along/south of the Red River, where unstable inflow and strong
   low/deep-layer shear (around 300 m2/s2 0-1 km SRH per FDR VWP) is in
   place. 

   Farther north in western/central OK, a messier convective mode
   evolution has limited the tornado risk thus far, with primarily a
   damaging-wind risk. However, the OUN 00Z sounding shows ample
   surface-based buoyancy/steep lapse rates and a large
   clockwise-curved hodograph (265 m2/s2 effective SRH) in the
   pre-convective environment. This could still support embedded
   mesovorticies/supercell structures with a risk of a couple tornadoes
   and severe wind gusts toward the I-35 corridor.
