    Areas affected...northern Mississippi

    Concerning...Tornado Watch 45...

    Valid 151620Z - 151745Z

    The severe weather threat for Tornado Watch 45 continues.

    SUMMARY...Strong to intense tornadoes are likely through
    mid-afternoon across northern Mississippi.

    DISCUSSION...Several mature, embedded supercells are starting to
    emerge out of the larger area of precipitation across northwest
    Mississippi with additional development possible from showers
    evident on radar across northeast Mississippi. One of these
    supercells, in Humphreys County, has had a persistent very strong
    mid-level mesocyclone and tops over 50kft. In addition, structural
    damage has been reported from this storm indicating the potential
    for a tornado. This supercell and any other mature supercells which
    develop are expected to persist east across the state through the
    early-to-mid afternoon. 0-1km SRH from the GWX VWP is around 350
    m2/s2 and increasing. The instability is not as great across
    northern Mississippi where extensive cloud cover has muted daytime
    heating somewhat. However, there is still ample instability for
    maintenance of ongoing supercells. The combination of instability
    and shear has yielded STP values of 2 to 3 which should increase
    through the early afternoon as both shear and instability increase.
    The 15Z WoFs shows several moderate low-level rotation tracks across
    the northern part of the state over the next several hours which
    supports expectations based on the aforementioned observational
    data. Therefore, several strong to intense tornadoes are likely over
    the next 2 to 3 hours across northern Mississippi within PDS Tornado
    Watch 45.
