    Areas affected...Parts of north TX

    Concerning...Severe Thunderstorm Watch 224...

    Valid 160250Z - 160415Z

    The severe weather threat for Severe Thunderstorm Watch 224
    continues.

    SUMMARY...Hail and one or more swaths of severe wind gusts may
    accompany an intense thunderstorm cluster as it moves southward
    across north Texas. Southward expansion of WW 224 may be needed.

    DISCUSSION...An intense supercell cluster is moving into north TX at
    0245Z. Strong buoyancy (MLCAPE > 3000 J/kg) and sufficient effective
    shear (30-40 kt) (noted on the 00Z FWD sounding and recent objective mesoanalyses), combined with an increasing southerly low-level jet
    noted on the KFWS VWP, will continue to support this cluster as it
    moves southward, though increasing MLCINH should eventually lead to
    a weakening trend later tonight.=20

    Large hail remains possible with the stronger embedded cells.
    However, some southward acceleration of the cluster has been noted
    in the last hour, potentially indicative of a strengthening cold
    pool, and wind gusts to 70 mph were noted across southern OK with
    the passage of this cluster. One or more swaths of severe wind gusts
    will be possible as this cluster spreads southward, potentially
    reaching the Metroplex by 0330-0400Z. Southward expansion of the
    watch may be required within the next hour.

    Areas affected...Northeastern KS into northwestern MO

    Concerning...Severe Thunderstorm Watch 218...

    Valid 130012Z - 130145Z

    The severe weather threat for Severe Thunderstorm Watch 218
    continues.

    SUMMARY...Storm intensification will continue from northeastern KS
    into northwestern MO during the next few hours.

    DISCUSSION...Latest radar data from KTWX shows a consolidating
    cluster of storms (with embedded mesocyclones) in northeastern KS,
    with additional discrete storms developing southwestward. Ahead of
    these storms, clockwise-turning hodographs (around 150 m2/s2
    effective SRH) and a warm/moist boundary layer should support
    continued storm intensification with northeastward extent during the
    next few hours. A tornado was recently observed with this activity,
    and this threat should continue during the next few hours.
