    Areas affected...parts of southeastern MS and southwestern through
    central AL

    Concerning...Tornado Watch 3...

    Valid 101304Z - 101500Z

    The severe weather threat for Tornado Watch 3 continues.

    SUMMARY...The risk for additional tornadoes, perhaps including a
    strong tornado, and damaging wind gusts will continue at least
    another couple of hours with an organizing cluster of storms
    approaching Montgomery AL and areas to the west and north through
    8-10 AM CST.

    DISCUSSION...Stronger convection along a pre-frontal confluence
    zone, generally aligned with a developing 40-45 kt southwesterly 850
    mb jet axis, has evolved into an organizing east-northeastward
    advancing quasi-linear convective system. This appears supported by southeasterly low-level inflow of seasonably moist boundary-layer
    air characterized by CAPE up to 1000 J/kg. This air mass, including
    surface dew points near 70F, extends in a corridor across the Mississippi/Alabama Gulf coasts through central Alabama, between
    Montgomery and Birmingham, and appears likely to maintain strong
    storms at least several more hours.

    The Rapid Refresh suggests that the low-level jet may strengthen
    further while nosing toward the southern Appalachians through
    14-16Z, perhaps including southerly 850 mb flow up to 50 kts as far
    south as the Montgomery AL vicinity. The most notable convection,
    including a sustained supercell which earlier may have produced a
    tornado, and has now evolved into a bowing structure in radar
    reflectivities with a broadening circulation on its northern end,
    appears to coincide with one low-level speed maximum. This has
    crossed into Alabama and may continue to pose the most prominent
    potential for additional tornadoes and/or damaging wind gusts as it
    approaches areas near and northwest of Montgomery AL through mid
    morning.
