    Areas affected...Southeast PA...NJ...northern MD/DE

    Concerning...Severe Thunderstorm Watch 605...606...

    Valid 062231Z - 070000Z

    The severe weather threat for Severe Thunderstorm Watch 605, 606
    continues.

    SUMMARY...Gusty winds will accompany convection as it propagates
    east-southeast this evening. Some consideration is being given to a
    new WW into portions of northern MD/DE; however, ongoing convection
    may only clip adjacent regions just south of Severe Thunderstorm
    Watches 605/606.

    DISCUSSION...Considerable amount of convection has evolved along the
    southern portions of stronger westerly flow, immediately ahead of a
    progressive short-wave trough. Multiple clusters and several line
    segments extend across the OH Valley into eastern PA/northern NJ.
    One notable MCS is propagating across the southeast portions of
    ww605 into southwest ww606. Over the last hour or so the southern
    flank of this complex has gradually sagged to near the PA/MD border.
    It's very warm just south of this activity into northern MD where
    surface temperatures are holding in the 90s. There is some concern
    this MCS may propagate into northern MD/DE which is not currently in
    a Severe Thunderstorm Watch. Gusty winds should accompany these
    storms. Will continue to monitor for possible ww.
