    Areas affected...southern MS into southwest AL

    Concerning...Severe potential...Watch possible

    Valid 031513Z - 031615Z

    Probability of Watch Issuance...40 percent

    SUMMARY...A locally damaging wind threat may develop this morning.
    Convective trends will be monitored in the short term as to whether
    a tornado watch will be needed prior to an expected tornado watch
    issuance time by the 11am-12pm period.

    DISCUSSION...Radar imagery shows an intensifying band of
    thunderstorms over southern MS from near the surface low
    southwestward along the cold front. The developing band of storms
    is expected to move eastward near the primary frontal zone extending
    eastward from the surface low across south-central AL. The maritime
    warm front near the I-10 corridor is becoming more diffuse with time
    but the airmass along and south of the front is where appreciable
    surface-based buoyancy resides. As such, only weak instability is
    located currently over east-central MS to the east of Jackson.
    Nonetheless, as additional boundary layer warming/moistening occurs,
    the combination of a destabilizing boundary layer and the fast
    eastward motion of the squall line (40-45 kt) may facilitate an
    increased risk for horizontal momentum transport in the form of
    strong to locally severe gusts in the next 1-2 hours. If this
    appears imminent, a tornado watch may be needed sooner than a
    currently anticipated tornado watch issuance time by 11am-12pm CST.
