Areas affected...the Arklatex area

Concerning...Severe potential...Watch unlikely=20

Valid 181208Z - 181345Z

Probability of Watch Issuance...20 percent

SUMMARY...An area of elevated storms may produce isolated severe
hail or locally strong gusts as it moves across the Arklatex.

DISCUSSION...West/southwest winds around 30 kt at 850 mb are helping
to maintain an feed of unstable air out of northern TX into the
Arklatex area. The storms currently appear elevated atop the old
outflow, which may reduce wind gusts potential in the short term.
However, strong surface-based instability is not too far south of
this developing complex, and some increase in severe potential could
occur later this morning over parts of eastern TX into northwest LA.
As such, trends will need to be monitored closely for any further
organization, including further backbuilding toward the warmer
surface instability, and/or increasing hail cores well beyond 1.00"
diameter.
