    Areas affected...Southeast Texas to much of Louisiana.

    Concerning...Tornado Watch 234...

    Valid 062048Z - 062215Z

    The severe weather threat for Tornado Watch 234 continues.

    SUMMARY...Continued threat for severe wind gusts, tornadoes, and
    isolated hail.

    DISCUSSION...A well-developed line of storms extends from
    east-central Texas to northwest Louisiana. Sporadic wind damage and
    at least one tornado has been reported thus far within the line. A
    more favorable orientation of the line has occurred across northeast Texas/northwest Louisiana where a bowing segment is apparent. In
    addition, a tornado with a TDS was recently observed southwest of
    the SHV radar where a leading supercell interacted with this line.
    Limited surface base instability amid mid 60s dewpoints and
    preceding rainfall should keep the tornado threat somewhat limited,
    but enough surface based or near surface based instability is
    present for some tornado threat near the apex of this bow,
    particularly where any cell interactions occur. Expect the greatest
    severe wind threat near this bowing segment of the line across
    northern Louisiana this afternoon and into the early evening.
    Farther south, isolated large hail and severe wind gusts are
    possible, particularly with any embedded supercells within the line.

    A conditional greater tornado threat exists with any supercells
    which can develop along/south of the warm front in Louisiana where
    STP values are around 2 to 3. STP values may increase this evening
    as low-level shear strengthens. Convection strengthening across
    southeast Texas could be the beginning of this potential threat. If
    any of these supercells can remain discrete with sufficient
    longevity to mature, they will pose a strong tornado threat this afternoon/evening.
