....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
SOUTH-CENTRAL AND SOUTHEAST TEXAS...

....SUMMARY...
Marginally severe storms capable of strong wind gusts and hail will
be possible on Saturday across parts of south-central and southeast
Texas.

....South-central and Southeast Texas...
A shortwave trough will move toward the southern Plains on Saturday,
as zonal flow remains in place across much of the Gulf Coast region.
At the surface, a quasi-stationary front is forecast to be located
across south-central and southeast Texas. South of this boundary, a
moist airmass will be in place with surface dewpoints in the 60s F.
Surface heating will result in destabilization across this airmass
during the day. As instability peaks during the afternoon, and as
low-level convergence increases along and near the front, scattered
thunderstorm development is expected. ECMWF forecast soundings in
south-central Texas during the late afternoon suggest that MLCAPE
will peak near 1200 J/kg, and that 0-6 km shear will be around 40
knots. This would be favorable for an isolated severe threat. The
stronger storms could be associated with isolated damaging wind
gusts and hail. However, limited large-scale ascent and poor lapse
rates will likely keep any severe threat marginal.
