    Areas affected...Parts of eastern Oklahoma

    Concerning...Tornado Watch 2...

    Valid 022345Z - 030115Z

    The severe weather threat for Tornado Watch 2 continues.

    SUMMARY...A narrow corridor of tornado risk remains for parts of
    eastern Oklahoma. Storms will eventually encounter rain-cooled air
    in Arkansas and Missouri. The need for an additional watch for
    southwest Missouri appears uncertain at this time.

    DISCUSSION...A few isolated storms continue in parts of eastern
    Oklahoma. Temperatures have cooled to the upper 60s F in this area
    over the last 1-2 hours. Farther north and east, rain-cooled air is
    more prevalent. Surface winds remain backed in eastern Oklahoma into northwestern Arkansas. The potential for tornadoes should continue
    for another hour or two. Once storms progress farther north/east,
    less favorable thermodynamics should limit begin to limit the
    threat. Even so, some risk for large hail and damaging gusts likely
    will persist with mature supercell storms as they move into
    northwest Arkansas and southwest Missouri. Though no Missouri
    counties are currently in a watch, temperatures in the low 60s F do
    make it unclear how much risk will exist. At present, the need for a
    downstream watch for parts of southwest Missouri appears uncertain.

    Areas affected...Portions of Southern New England

    Concerning...Heavy snow=20

    Valid 071716Z - 072015Z

    SUMMARY...Moderate to heavy snow expected through the afternoon with
    rain transitioning to snow near the coast.

    DISCUSSION...Snow is intensifying across portions of southern New
    England as the surface low intensifies over the Atlantic and
    low-level wind fields strengthen. Snowfall rates of 1 to perhaps 2
    inches per hour are expected through the afternoon before moving
    offshore by this evening. Areas near the coast which have been
    mostly rain thus far due to winds off the ocean will transition to
    snow in the next few hours as winds shift more northerly as the
    cyclone deepens/moves east. In addition, sustained winds around 15
    mph with gusts of 25 to 30 mph may lead to some blowing and drifting
    snow and additional visibility restrictions through the afternoon.
