    ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF
    CENTRAL INTO EAST TEXAS...

    ...SUMMARY...
    Severe thunderstorms are possible across much of Central into East
    Texas and western/central Louisiana. All severe hazards would be possible.

    ...Synopsis...
    An ejecting shortwave trough will lift northeastward through Central
    into Northeast Texas on Tuesday. Continued moisture advection
    northward will bring upper 60s to low 70s dewpoints in
    South/Central/Southeast Texas and parts of the lower Mississippi
    Valley. Early period precipitation appears likely along a warm front
    within the Red River region southeastward into Louisiana. Additional
    early precipitation is possible within the Edwards Plateau into
    Central Texas, but uncertainty is greater in this scenario. A
    dryline is expected in central Texas during the afternoon.

    ...Central Texas into Sabine Valley...
    The expectation of early day precipitation complicates the overall
    forecast for the afternoon. Even so, a very moist and weakly capped
    airmass is forecast to be in place south of the warm front and east
    of the developing dryline. The ECMWF is more aggressive with the
    early development of a cluster of storms/MCS. In this scenario,
    convection would likely strengthen as surface heating occurs ahead
    of it. The GFS/NAM show greater potential for the dryline to be a
    focus for convection during the afternoon. Here, supercells capable
    of all hazards would be possible. There is potential for significant
    severe, with very large hail being the primary concern, but
    uncertainty in the convective evolution keeps confidence too low to
    highlight any particularly area.

    ...Red River into ArkLaTex...
    Storms along the warm front will likely be ongoing early in the day
    and continue to develop within the warm advection regime into the
    afternoon. Strong shear and moderate buoyancy would promote a risk
    for large hail and damaging winds. Numerous storms and their
    interactions will tend to temper the overall severe threat. Many of
    these storms will be at least slightly elevated north of the
    boundary. Tornadoes could also occur with surface-based storms
    within the warm front zone.
