    Areas affected...southwest Missouri into northern Arkansas

    Concerning...Tornado Watch 343...

    Valid 192247Z - 200045Z

    The severe weather threat for Tornado Watch 343 continues.

    SUMMARY...The threat of damaging winds and a few brief tornadoes
    continues across the watch area.

    DISCUSSION...Storms continued to develop across southwest MO and
    northwest AR, ahead of a weak surface low and near a diffuse warm
    front. The latest surface analysis indicates 2 hr pressure falls in
    excess of 2 mb, associated primarily with low-level warm air
    advection. Hodograph size on the SGF VAD wind profile has gradually
    been increasing, now with 0-1 SRH in excess of 200 m2/s2. This trend
    may persist over the next couple hours, coincident with an increase
    in the 850 mb flow. As such, the north-south oriented line of storms
    that moved out of KS into MO is becoming more of a QLCS with swaths
    of damaging wind and/or brief tornadoes possible.

    To the south and closer to the warm front, cells over AR are more
    robust overall in terms of being instability driven with hail cores
    evident on radar. Low-level shear is not as strong as farther north,
    but a brief tornado cannot be ruled out with this activity.
