Areas affected...Parts of the eastern Texas Panhandle

Concerning...Severe Thunderstorm Watch 603...

Valid 250218Z - 250315Z

The severe weather threat for Severe Thunderstorm Watch 603
continues.

SUMMARY...A localized risk of severe hail and wind continues across
parts of Severe Thunderstorm Watch 603 in the eastern Texas
Panhandle.

DISCUSSION...The latest radar data from KAMA shows ongoing
convection moving southward across the eastern TX Panhandle,
including one discrete supercell moving across Gray/Donley Counties.
This storm is approaching the southern edge of a weakly unstable air
mass, where around 30 kt of effective shear will continue to promote
a risk of large hail and locally severe gusts in the near term.
However, given limited residence time in the surface-based buoyancy
and a gradual increase in nocturnal PBL static stability, the severe
risk should gradually decrease over the next couple hours, and a
downstream watch is not currently expected.
