    Concerning...Tornado Watch 350...

    Valid 302240Z - 310045Z

    The severe weather threat for Tornado Watch 350 continues.

    SUMMARY...A local corridor of greater tornado threat is evident in
    the DC/Baltimore region over the next 1-3 hours.

    DISCUSSION...A narrow zone of favorably backed surface winds, south
    of a warm front near the PA/MD border, will be the most favorable
    corridor for tornadoes over the next 1-3 hours. Local VAD data from
    KLWX and nearby TDWRs show sufficient SRH for low-level mesocyclone development. A bookend vortex within a linear segment in northern
    Virginia will continue north-northeast into this favorable zone.
    Farther east, additional discrete storms will also have some
    potential to produce a tornado. The primary limiting factors will be
    modest buoyancy, weak mid-level lapse rates, and limited remaining
    time for surface heating.
