   The severe weather threat for Tornado Watch 110 continues.

   SUMMARY...Threat for severe thunderstorms capable of all severe
   hazards, including tornadoes and very large hail, remain possible.
   Localized area of greater tornado risk likely exists across central
   Texas for the next hour or two.

   DISCUSSION...Discrete supercells continue to move
   eastward/southeastward across north/central TX this evening. The
   southernmost pair of supercells, over Bosque/Hill and Coryell/Bell
   Counties, is upstream of a narrow corridor of more favorable
   low-level moisture and slightly stronger southeasterly surface
   winds. Recent surface observations along I-35 show dewpoints in the
   upper 60s to low 70s amid temperatures in the upper 70s to low 80s.
   Recent mesoanalysis estimates effective-layer STP is 4 to 5 in this
   region. As a result, additional storm intensification/organization
   is possible as the ongoing supercells enter this region. All severe
   hazards are possible, including very large hail and tornadoes.

   A more linear storm mode exists farther north over Grayson, Denton,
   and Collin counties, where storms have organized along the outflow
   boundary. Ample downstream buoyancy, as well as updraft augmentation
   due to interaction with the warm front, suggests these storms will
   persist downstream. Primary threats are damaging gusts and hail,
   although an embedded tornado is also possible on the southern end of
   the line where surface-based parcels are more probable.
