Areas affected...Parts of central/northeast TX into northwest LA

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

Valid 081352Z - 081545Z

Probability of Watch Issuance...20 percent

SUMMARY...Strong to locally severe storms remain possible through
the morning. The southward extent of development is uncertain.

DISCUSSION...The elevated supercells that earlier moved across parts
of north-central into northeast TX have weakened somewhat, though a
couple strong cells persist near the northeast Metroplex, while a
small elevated bowing cluster is approaching the ArkLaTex region.
The 12Z SHV/FWD soundings depict relatively cool profiles and MUCAPE
around 500 J/kg, though both also depict weak lapse rates in a
saturated layer above 600 mb. With effective shear remaining
favorable for organized convection, the ongoing storms may persist
and at least occasionally pose a localized threat of hail and strong
gusts, before generally moving into less-favorable instability with
eastward extent.=20

Farther south, rich low-level moisture (with mid/upper 60s F) is in
place near and south of a cold front draped from central into
northeast TX, with MLCAPE expected to increase to 500-1000 J/kg
later this morning. Recent HRRR runs depict storm development near
and just south of this front later this morning into parts of
east-central TX, possibly in response to a low-amplitude midlevel
shortwave trough moving across central TX. Should development occur
in this area, deep-layer shear will support organized storms, with a
somewhat greater conditional severe potential compared to areas
farther north. The scenario of storm development this morning near
the front or within the warm sector remains quite uncertain, but
will continue to be monitored.
