    Areas affected...Central Mississippi

    Concerning...Tornado Watch 125...

    Valid 022351Z - 030045Z

    The severe weather threat for Tornado Watch 125 continues.

    SUMMARY...Supercells with a history of tornadoes will likely persist
    through early evening where a corridor of greater tornado risk
    appears likely this evening.

    DISCUSSION...Several small supercells along and west of I-55 have
    produced confirmed tornadoes over the last 90 minutes. KDGX analysis
    shows several low-level mesocyclones with VROTs of 40-50 kts and a
    considerable TDS near Yazoo City, MS. SPC mesoanalysis and regional
    VWPS show strong veering wind profiles with 200-300 m2/s2 ESRH ahead
    of the ongoing storms to near the warm front across north-central
    Mississippi. A corridor of greater tornado potential is likely
    evolving. The potential exists for several additional tornadoes,
    (possibly significant) to develop and track northeastward to the
    warm front over the next 1 to 3 hours.
