    Areas affected...Northeast Texas into ArkLaTex

    Concerning...Severe potential...Watch possible

    Valid 021533Z - 021730Z

    Probability of Watch Issuance...40 percent

    SUMMARY...All severe hazards, including very-large hail and a strong
    tornado or two, are possible this afternoon.
    Convective/observational trends will continue to be monitored for a
    possible watch this afternoon.

    DISCUSSION...Storms have recently initiated along a pre-frontal
    confluence zone in Northeast Texas. Based on the observed 12Z
    Shreveport, LA sounding as well as the character of boundary layer
    clouds on visible satellite, there is still inhibition left to
    overcome this morning. That said, objective mesoanalysis shows more
    minimal amounts of MLCIN remaining right along the confluence zone.
    Activity may initially struggle to intensify until greater surface
    heating occurs through the day. Strong effective shear is in place,
    though it is largely parallel to confluence zone and cold front that
    lags to the northwest. 2000-2500 J/kg MLCAPE and steep mid-level
    lapse rates will eventually support rapid storm intensification. Large/very-large hail and severe gusts would be possible. The
    tornado threat will depend on the overall storm mode, which could
    lean linear, but strong low-level shear apparent on regional VAD
    data and a very moist airmass (mid/upper 60s F dewpoints) would
    favor potential for tornadoes, some of which could be strong. Timing
    of storm intensification is uncertain given the inhibition and
    overall lack of a stronger/focused forcing mechanism.
    Convective/observational trends will be monitored for a possible
    watch this afternoon.
