Concerning...Severe potential...Watch possible=20

Valid 241933Z - 242130Z

Probability of Watch Issuance...60 percent

SUMMARY...A cluster of thunderstorms continues to organize, with
signs of increasing potential to produce strong to severe gusts
while propagating southeastward toward the mid/upper Texas coastal
plain through 5-7 PM CDT.

DISCUSSION...Forcing for ascent associated with
lower/mid-tropospheric warm advection, and southeasterly updraft
inflow of seasonably moist boundary-layer air (characterized by CAPE
in excess of 2000 J/Kg), have maintained vigorous thunderstorm
development. Activity has undergone notable intensification and
increasing organization, and it appears that a meso-beta scale
cyclonic circulation is becoming better-defined near the Waco
vicinity, where a couple of 50+ kt surface gusts have recently been observed.=20=20

Despite continued gradual warming around 700 mb, and some suggestion
that the larger-scale forcing for ascent may weaken, the
boundary-layer ahead of the storms remains potentially supportive of
further intensification of the convective system, southeastward
toward the mid/upper Texas coastal plain into early evening.=20
Deep-layer mean flow and shear remain generally modest, as does the
strength of the surface cold pool (as of 19Z observational data).=20
However, with further strengthening of the mesoscale vortex and west-northwesterly rear inflow, there remains potential for a
continued increase in risk for strong to severe gusts during the
next few hours.
