    Areas affected...southeastern Arkansas...northern
    Louisiana...western and Middle Tennessee...northern
    Mississippi...and northern Alabama

    Concerning...Tornado Watch 326...328...329...

    Valid 270552Z - 270745Z

    The severe weather threat for Tornado Watch 326, 328, 329 continues.

    SUMMARY...Strong/locally severe storms continue within a band from
    northern and western Tennessee west-southwestward to the Arklatex.=20
    Risk for locally damaging winds and hail, and a tornado or two,
    continues. Southeastward expansion of the convection into northern
    parts of Mississippi and Alabama will likely require new WW
    issuance.

    DISCUSSION...Latest radar loop shows a continues line of storms
    extending west-southwest to east-northeast across northern Middle
    and western Tennessee, which is sagging slowly southward.=20
    Meanwhile, a broken -- but more intense -- band of storms extends
    from western Tennessee southwestward to the Arklatex region. This
    convection is ongoing within a much more unstable environment
    (mixed-layer CAPE 3000 to 5000 J/kg across this area), and is a bit
    less shear-parallel than the more west-to-east Tennessee band of
    storms.=20=20

    As this stronger convection shifts gradually eastward over the next
    1 to 2 hours, it will begin to impinge on eastern portions of WW 328
    and, later, 329. Other, isolated storms are also developing across northwestern Alabama, south of the Middle Tennessee line of storms.=20
    Overall, with ample instability extending into northern Mississippi
    and -- to a lesser degree -- northern Alabama, new WW issuance will
    likely be needed soon over portions of northern Mississippi and
    northern Alabama. Southeastward extent of the risk should remain
    limited (into Georgia, and central portions of Alabama), given much
    weaker instability, and higher convective inhibition.
