...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Friday.

...Synopsis...

An upper low over the southern Plains will develop eastward as an
open wave across the southeastern states. At the surface, a weak low
near the OK/north TX border will weaken as it develops southeast.
Gulf return flow will remain limited to the TX coastal Plain and
portions of the Sabine Valley. However, low level moisture will
remain shallow, with low 60s dewpoints hugging the coast while upper
40s to 50s dewpoints extend further north. Steepening midlevel lapse
rates will help contribute to less than 500 J/kg MLCAPE. Stronger
forcing will remain displaced to the north/northeast of low-level
moist axis, but moderate shear and weak elevated instability should
allow for isolated thunderstorms ahead of a surface cold front.
Severe storms are not expected.
