    Areas affected...Upstate NY to eastern Long Island...including parts
    of southern New England

    Concerning...Heavy snow=20

    Valid 262341Z - 270545Z

    SUMMARY...Heavy snow bands will spread/develop southeast across
    upstate NY toward southern New England over the next few hours. Snow
    rates of 1-1.5"/hr are expected.

    DISCUSSION...Low-amplitude short-wave trough is progressing
    southeast across western NY/PA early this evening. Latest
    water-vapor imagery depicts a notable midlevel vort max southwest of
    Syracuse, and this is reflected well in radar data. Multiple heavy
    snow bands have developed ahead of this vort max, strongly
    influenced by low-level warm advection, extending across upstate NY
    into the lower Hudson Valley. Boundary layer moistening supports
    this with dew points now rising into the mid teens (F) where snow
    rates are increasing. Over the next few hours snow rates are
    expected to increase downstream across western CT and Long Island,
    largely in response to this well-defined short wave digging toward
    the northern Middle Atlantic. Snow rates of 1-1.5"/hr can be
    expected prior to the short wave passage.

    Areas affected...far eastern Indiana into western/central Ohio

    Concerning...Severe potential...Watch unlikely

    Valid 092318Z - 100115Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated strong to severe gusts will be possible with
    storms developing near the cold front this evening.

    DISCUSSION...Thunderstorm development is noted near the cold front
    across far eastern Indiana into western/central Ohio. While a narrow
    axis of marginal to moderate instability remains ahead of the front,
    deep layer flow decreases with southern extent into central/southern
    Ohio as the primary region of mid-level flow is moving off to the
    northeast. Temperatures in the mid to upper 80s across
    southern/central Ohio are supporting steep low-level lapse rates but temperatures will continue to gradually cool this evening. A few
    instances of strong to severe wind may be possible before sunset.
    Given the likely short duration and isolated threat, a watch is
    unlikely to be needed.
