    Areas affected...southeastern Mississippi and far southwest Alabama

    Concerning...Tornado Watch 186...

    Valid 070031Z - 070130Z

    The severe weather threat for Tornado Watch 186 continues.

    SUMMARY...An intense supercell with a recent strong tornado is
    ongoing and expected to continue. The environment remains very
    favorable for strong tornadoes across southeastern MS and southwest
    AL.

    DISCUSSION...As of 0020 UTC, local radar imagery showed an intense
    supercell with a recent, likely strong, tornado ongoing over
    portions of southern Forest County in southeastern MS. This
    supercell is ongoing in an an environment with STP values of 2-3.
    The MOB VAD shows an enlarged hodograph with 200-300 m2/s2 of
    effective SRH. This strongly suggests this discrete supercell will
    continue eastward with a risk for tornadoes (possibly strong to
    intense) this evening. Current tracking (240 degrees at 40 kt)
    extrapolates this storm across the MS/AL state line near 0100 to
    0130 UTC (8 to 830 CDT). Large hail and damaging winds also remain
    possible.
