    ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF NORTH-CENTRAL INTO CENTRAL TEXAS...

    ...SUMMARY...
    Very large hail with multiple supercells appears probable across
    parts of north-central into central Texas Thursday afternoon and
    evening. A broader corridor of severe hail and damaging wind
    potential remains evident from the lower Mississippi
    Valley/Southeast into the Carolinas and Mid-Atlantic.

    ...Central/East Texas into the Lower Mississippi Valley...
    With steep mid-level lapse rates present atop a very moist low-level
    airmass, strong to extreme instability is anticipated across parts
    of north-central and central TX, along/south of a cold front, and to
    the east of a dryline. A weak mid-level perturbation emanating from
    northern Mexico should support convective initiation across
    central/east TX by late Thursday afternoon. Strong deep-layer shear
    will support organized convection, including scattered supercells
    posing a threat for very large hail. Due to increased confidence in
    this very large hail threat occurring, an Enhanced Risk has been
    included for parts of north-central into central TX. This convection
    may spread eastward Thursday evening/night across the lower MS
    Valley/Southeast in the form of a small cluster/bow, while still
    posing a threat for damaging winds and hail given a favorably
    unstable airmass along/south of the front.

    ...Deep South into the Carolinas and Mid-Atlantic...
    Across the Southeast, one or more clusters may be ongoing Thursday
    morning along the southward-sagging cold front. An MCS posing a
    threat for mainly damaging winds may eventually strengthen through
    the late morning and early afternoon, and spread
    east-southeastward across parts of GA/SC while posing a threat for
    mainly damaging winds. The potential for additional strong to severe
    storms across AL/MS through the day remains uncertain. Farther north
    into NC and Mid-Atlantic, the severe potential remains a bit more
    uncertain due to possible convective contamination/overturning with thunderstorms in the Day 1 (Wednesday) period. Still, weak to
    moderate instability may develop ahead of the cold front with
    daytime heating behind whatever morning convection may have
    occurred. Mid-level flow and related deep-layer shear will increase
    through the day with the eastward progression of an upper trough.
    Isolated to scattered thunderstorms should gradually increase in
    coverage and intensity through the afternoon, generally along/east
    of the Blue Ridge and Appalachian Mountains. Hail and damaging winds
    will be a concern with any clusters or supercells that can develop
    and spread east-southeastward towards the Atlantic Coast through
    Thursday evening.
