   The severe weather threat for Tornado Watch 354 continues.

   SUMMARY...A tornado, very large hail, and severe damaging wind
   threat continues across the tornado watch.

   DISCUSSION...Two confirmed tornadoes were recently reported very
   close to MAF and briefly Denver City, in addition to very large
   hail. The supercell near MAF continues to interact with the same
   outflow boundary, and remains in a favorable environment for
   additional tornadogensis cycles. The KMAF VAD indicated 0-1 km SRH
   around 250-350 m2/s2 when the tornado occurred, and recent
   mesoanalysis suggests a broad area within southeasterly surface flow
   just behind the modified outflow boundary of 150-200 m2/s2 0-1 km
   SRH. In addition, steep mid-level lapse rates are contributing large
   CAPE within the hail growth zone as depicted in local RAP soundings.
   Increasing low-level shear and moisture advection will continue
   through the evening hours as a LLJ slowly intensifies. A discrete
   storm mode is expected to continue (deep layer effective shear 55-60
   kt normal to forcing) before mergers occur late this evening.
