   Areas affected...West-central Texas

   Concerning...Tornado Watch 49...

   Valid 140232Z - 140430Z

   The severe weather threat for Tornado Watch 49 continues.

   SUMMARY...Isolated severe threat expected to continue this evening
   across west-central Texas. Wind damage, large hail and a tornado
   will be possible. Although a local extension in time may be
   necessary, particularly for a supercell to the west-southwest of
   Midland, the threat should be too isolated for new weather watch

   DISCUSSION...Latest surface analysis shows a 1009 mb low across far
   West Texas with a moist airmass in place southeast of the low.
   Surface dewpoints are in the lower 60s F with an axis of moderate
   instability located from just south of Midland southeastward into
   the southern Texas Hill Country. Thunderstorms that are ongoing in
   west-central Texas are located along the northern edge of the
   stronger instability. In addition, the Midland WSR-88D VWP has 0-6
   km shear near 80 kt with a curved hodograph. For this reason, a
   severe threat, specifically associated with a supercell near I-20 to
   the west-southwest of Midland, should continue across west-central
   Texas for several more hours. Supercells will have potential for
   wind damage, large hail and perhaps a tornado. 

   However, the severe threat had become more isolated in the last
   hour. This trend may continue as surface temperatures decrease
   across the region, and weather watch issuance is not expected.
