Areas affected...Parts of north-central Texas

Concerning...Tornado Watch 295...

Valid 200042Z - 200215Z

The severe weather threat for Tornado Watch 295 continues.

SUMMARY...Risk of large hail and severe wind gusts continues, with
embedded tornadoes also possible. A local time extension of Tornado
Watch 295 may be needed, depending on storm evolution over the next
hour.

DISCUSSION...At the tail-end of a continuous convective line
extending from southeast/south-central OK into north-central TX, a
couple embedded supercells are impinging on an air mass
characterized by 3200 J/kg MLCAPE (sampled by FWD 00Z sounding) and
300 m2/s2 0-1km SRH (per FWS VWP). With mostly line-parallel
deep-layer shear, a mostly linear mode with embedded supercells
should continue. Severe wind gusts and large hail are the main
concerns, though the aforementioned streamwise vorticity amid any
deep/embedded rotating cores will still support a tornado risk for a
couple more hours. A local time extension of Tornado Watch 295 may
be needed -- depending on storm evolution over the next hour.
