Areas affected...central Texas

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

Valid 171946Z - 172115Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated supercells are possible in central Texas this
afternoon/evening.

DISCUSSION...The day-cloud RGB band from GOES-16 shows agitated
cumulus through the upper clouds along a moisture boundary moving
north through central Texas. SPC mesoanalysis shows some CIN in the
vicinity, but with additional heating/moistening, expect a mostly
uncapped environment within the next 1 to 2 hours. Forcing in the
region is weak, but convergence along this boundary (evident in
moisture convergence on SPC mesoanalysis) may be sufficient to break
the cap. If any storms develop, the mode will be supercellular given
55 knot of effective shear and 1500 J/kg MLCAPE. Long, straight
hodographs will support splitting supercells. Given the lack of
greater forcing, expect the threat to remain isolated to only one or
two storms with the threat waning near sunset as the boundary layer
cools.
