    ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR PARTS OF
    EAST TEXAS INTO NORTHWEST LOUISIANA AND FAR SOUTHWEST ARKANSAS...

    ...SUMMARY...
    Several tornadoes will be possible today, in association with
    Tropical Cyclone Beryl, from southeast Texas into northwest
    Louisiana and far southwest Arkansas.

    ...East Texas/Ark-La-Tex/Ozarks/Lower to Mid Mississippi Valley...
    Tropical Cyclone Beryl will continue moving north across
    southeast/east TX through the day before moving north-northeast into
    the Ark-La-Tex tonight per the latest NHC forecast. The extensive
    rain shield has yielded intermittent periods of transient mini
    supercell structures within the convective bands early this morning.
    Thinking this trend will continue during the day across
    southeast/east TX into western portions of LA. Ample low-level shear
    for hodograph enlargement will reside over the right-front quadrant
    of Beryl. Less certain will be the development of moderate buoyancy
    within the rain shield. Nonetheless, some evolution into more
    coherent convective banding is expected during the diurnal heating
    cycle (midday into the early evening) when the risk for several
    supercell tornadoes will probably be greatest. An isolated tornado
    threat should continue through the evening and into the overnight
    period as this risk shifts northward coincident with the movement of
    Beryl.

    ...Southwest Texas...
    At the surface, a cold front is forecast to move across west Texas
    today. South of the front in the vicinity of Big Bend, surface
    dewpoints are likely to be from the mid 50s to the lower 60s F. As
    surface temperature warm across this relatively moist airmass and
    yield moderate buoyancy. Increasing low-level convergence along the
    front during the afternoon should enable scattered thunderstorms to
    develop. A couple of the stronger storms may result in a localized
    hail/wind risk before this activity weakens this evening.

    ...Northern NM...
    Water-vapor imagery this morning shows an upper trough from the
    Upper Midwest extending southwestward into the CO/NM vicinity. A
    belt of moderate north-northwest flow will gradually pivot away from
    the region during the day. However, a relatively moist airmass via
    easterly upslope/post-frontal flow will combine with strong heating
    to yield around 1000 J/kg MLCAPE. A few stronger storms may develop
    with a possible localized hail/wind risk for a few hours late this
    afternoon.
