    Areas affected...Much of Arkansas

    Concerning...Tornado Watch 177...

    Valid 290029Z - 290230Z

    The severe weather threat for Tornado Watch 177 continues.

    SUMMARY...Scattered severe storms continue to track across Arkansas
    this evening, with a risk of large hail, damaging winds, and a few
    tornadoes.

    DISCUSSION...Three distinct clusters of intense storms continue to
    track eastward across AR, over Van Buren, Yell, and Hempstead
    counties. These storms will likely persist eastward across WW177
    for several more hours, where moderate CAPE and sufficiently strong
    low-level shear will maintain the risk of supercells and a few
    tornadoes. Strong tornadoes are possible if more discrete storm
    modes develop. The LZK VAD is sampling the strengthening wind
    fields, now showing over 500 m2/s2 of 0-3 SRH and STP values over 5.


    Increased warm advection/lift has led greater coverage of storms in
    the past 2 hours. This activity will spread eastward and to the
    west of WW177 this evening, likely requiring a new watch in the next
    hour or two over eastern AR/west TN and northern MS.
