Areas affected...central TX

Concerning...Tornado Watch 177...

Valid 282023Z - 282130Z

The severe weather threat for Tornado Watch 177 continues.

SUMMARY...An intense supercell ongoing in Coryell, County TX is in a
favorable mesoscale environment for tornadoes and will likely
continue for the next hour.

DISCUSSION...As of 2015 UTC, hi-res radar imagery showed a
well-developed supercell over portions of Coryell county Texas.
Based on an STP environment around 3 and VROT greater than 70kt,
there is the potential for this storm to produce a strong tornado.
VAD winds AT GRK at 925 MB have increased and backed to 35 kt from
the south, supporting greater low-level shear with strong buoyancy
(3000 J/kg of MLCAPE). Additional storm development along the
southwestern flank of the storm may eventually favor upscale growth
into a bowing MCS. However, this intense supercells is likely to
persist in an environment favorable for a strong tornado for at
least the next hour as it moves southeast.
