    ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PORTIONS OF
    THE NORTHEAST TO THE CENTRAL GULF COAST/SOUTHEAST STATES...

    ...SUMMARY...
    Strong/severe thunderstorms are forecast Monday from portions of the
    Northeast southwestwad to the central Gulf Coast region.

    ...Portions of New York and Pennsylvania south-southwestward to the
    central Gulf Coast...

    Showers and thunderstorms are expected to be ongoing along/ahead of
    a cold front just west of the Appalachians at the start of the
    period/Monday morning. Severe weather is likely to accompany some
    of the early-period convection. As the front advances across the
    higher terrain through the afternoon, some destabilization is
    expected -- modest across the Northeast, but more substantial with
    southward extent, from roughly Virginia southward. This will
    support an increase in storm coverage/intensity through the
    afternoon hours.

    Across northern portions of the outlook, the primary risk in the
    very modest CAPE environment will be locally damaging wind gusts.
    Farther south, an all-hazards risk is anticipated, including hail
    and potentially a few tornadoes. As is the case for Sunday, farther
    west, the NAM remains more bullish with respect to lapse rates/CAPE,
    and would support potentially greater than SLGT risk potential from
    roughly the Carolinas southwestward to Georgia and southern Alabama.
    However, uncertainty regarding pre-frontal clouds/convection across
    the Southeast early precludes inclusion of higher probabilities at
    this time.

    By evening, storms moving into southern New England should weaken,
    along with diminishing severe potential in part due to a cooler
    marine boundary layer. However, risk will likely continue through
    the evening farther south, until storms clear the middle and
    southern Atlantic coasts overnight.
