    Areas affected...portions of the mid-Atlantic

    Concerning...Severe Thunderstorm Watch 634...

    Valid 182030Z - 182200Z

    The severe weather threat for Severe Thunderstorm Watch 634
    continues.

    SUMMARY...Scattered strong to severe storms are expected to persist
    into the evening.

    DISCUSSION...Scattered thunderstorms have developed within the
    unstable airmass across eastern Pennsylvania and Delaware and are
    moving into New Jersey and southwest New York. These storms have
    been mostly multicellular in nature with a few reports of damaging
    winds and large hail. These storms may be somewhat more productive
    in the next 1 to 2 hours as they move into a hotter airmass across
    New Jersey which was not impacted by morning clouds.

    The airmass continues to destabilize to the lee of the Appalachians
    where temperatures have warmed into the mid to upper 80s. Short term
    guidance (18Z HRRR and hires NAM) continues to suggest an additional
    round of thunderstorms may develop this evening and move into the
    I-95 corridor near sunset.
