This is a Storm Warning Alert by NYC
Thu Feb 07 18:21:06 2013
STATUS: Open - Active
PROGNOSIS: Monitoring Weather-Snow
High pressure over the area will begin to retreat north tonight as an
area of low pressure over the mid-west approaches the area. This will
allow for cloudy skies and increases chances for snow late tonight into
Friday morning. A light easterly flow will increase tonight with the
approach of the system. Lows will range from the upper teens to lower
20s inland to upper 20s to near 30 in the New York metro area.
As the low over the mid-west approaches, low pressure over the southeast
U.S. will push off the east coast and head northeast Friday morning.
This low will become the dominant storm as it approaches the tri-state
area. Snow will continue Friday morning for the entire area. The snow
will mix with and possibly change over to rain over portions of Long
Island, New York City, and northeast NJ by the afternoon. It will
remain all snow, coming down heavy at times for inland areas. As the
storm approaches, it will strengthen, and winds will continue to
increase, with gusts 45 to 55 mph, especially for eastern areas.
A changeover back to snow is expected by early Friday night for areas
that will mix or change over to rain prior. Blizzard conditions are
expected, with heavy snow, wind gusts increasing to 45 to 60 mph, and
visibilities reduced to 1/4 miles or less. The snow will continue into
early Saturday morning and taper off by late morning into the early
afternoon. 12 to 16 inches are forecast for Long Island, New York City,
and northeast NJ, and the lower Hudson Valley with up to 2 feet in
portions of southeast CT. Locally higher amounts are possible,
depending on where the heaviest snow sets up. Additionally, coastal
flooding will also be a concern for portions of Long Island and
southwest Connecticut Friday evening.
