    Areas affected...West central Arkansas

    Concerning...Severe Thunderstorm Watch 126...

    Valid 160344Z - 160515Z

    The severe weather threat for Severe Thunderstorm Watch 126
    continues.

    SUMMARY...Occasional wind damage and/or a brief tornado or two will
    be possible with bowing segments/mesovortices through 05-06z.

    DISCUSSION...The bowing line segment across west central AR has
    maintained intensity for the past 1-2 hours. The downstream
    environment is sufficiently buoyant to support strong updrafts.=20 Additionally, the SRX VWP shows a 40-50 kt rear-inflow jet and low-level/deep-layer shear vectors (per LZK VWP) are oriented
    favorably across the N-S line segment to maintain updrafts tied
    closely to the leading edge of the cold pool. In the near term,
    these factors will maintain the threat for occasional wind damage
    and a brief tornado or two with mesovortices in the line. By
    06-07z, the storms will likely move east of any substantial buoyancy
    and are expected to weaken.
