    Areas affected...Central Arkansas

    Concerning...Severe Thunderstorm Watch 263...

    Valid 020007Z - 020200Z

    The severe weather threat for Severe Thunderstorm Watch 263
    continues.

    SUMMARY...The best potential for severe winds will likely emerge
    across parts of central Arkansas over the next 1-2 hours as outflow
    begin to collide.

    DISCUSSION...Recent velocity data from KLZK shows strong velocities
    between 1-2 kft ARL north of the I-40 corridor as a loosely
    organized band of storms becomes increasingly outflow dominant. At
    the surface, wind gusts between 35-40 mph have been noted with the
    passage of the outflow. Similarly, a second outflow boundary is
    noted with a second convective cluster to the north/northeast of the
    Little Rock area. GOES 1-minute imagery continues to show updraft
    pulses along the leading edge of both outflow boundaries as they
    push generally southward into an uncapped and highly buoyant
    environment. Consequently, it appears possible that some uptick in
    thunderstorm coverage will occur as these outflow boundaries begin
    to collide near and north of the Little Rock area, and could result
    in a focused corridor of relatively higher damaging wind potential
    over the next 1-2 hours.
