Areas affected...North Central Texas

Concerning...Severe Thunderstorm Watch 282...

Valid 132249Z - 140015Z

The severe weather threat for Severe Thunderstorm Watch 282
continues.

SUMMARY...Isolated thunderstorms will continue to develop, primarily
across eastern portions of ww282 into northeast Texas.

DISCUSSION...Weak short-wave ridging is currently noted across
north-central TX ahead of the next short-wave trough advancing into
the southern High Plains. Expansive low clouds extends across much
of north TX into the Arklatex, north of a surface boundary that is
draped from near Tyler to near Stephenville to near San Angelo.
Modest MUCAPE exists atop the cooler boundary layer where steep
lapse rates are observed. In the absence of meaningful large-scale
ascent, weak low-level warm advection atop this air mass appears to
be the primary mechanism for new updraft development. Satellite
imagery suggests isolated towers continue to evolve over the eastern
Metroplex but this activity should mature mostly downstream over the
Arklatex, as 850mb flow has veered toward into this region. Any
storms that mature north of the wind shift continue to pose some
hail risk.
