    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.
