.WHAT HAS CHANGED...
Small Craft Advisory on the ocean has been extended thru this
eve.

&&

.KEY MESSAGES...
1) Areas of black ice possible through Saturday night.

2) Brief period of light snow Sunday as an arctic front moves
through the region. Much colder than normal temperatures
expected behind this front Sunday night through Tuesday.

3) A series of waves of low pressure move nearby next week
bringing multiple chances for precipitation.

&&

.DISCUSSION...
.KEY MESSAGE 1...
A warming trend thru Sat will result in snowmelt each day, but
subfreezing temps each night. This will result in the potential
for black ice formation each night across the area. In addition,
light return flow off the ocean may allow for increased llvl
moisture and icing risks Fri and Sat nights, along with some
patchy freezing fog. The better chances for fog may be Sat night
ahead of the next cold front.

.KEY MESSAGE 2...
An arctic front moves through the region late Saturday night into
Sunday accompanied by some moisture and upper shortwave energy. A
brief period of light snowfall is still possible, mainly Sunday
morning, as this front pushes through the region.
At this time less than an inch of snowfall is expected, with high
end amounts of up to an inch. An arctic airmass moves into the
region behind the front with temperatures expected to be below
normal, as much as around 10 degrees, Sunday through Tuesday.
Northerly winds will be light, generally 10 mph or less, with wind
chill values as low as zero to around 10 degrees above zero Sunday
night, and 10 to 15 degrees Monday night.

.KEY MESSAGE 3...
A series of waves of low pressure pass near the region Monday
through Thursday, with chances of precipitation.

High pressure will be over the region Monday, and the first wave of
low pressure has trended farther to the south. A chance of light
snow remains possible with this wave Monday into Monday evening. At
this time this event will bring sub advisory snowfall to the region,
with the potential of high end amounts at advisory levels.

Another wave passes near the region late Tuesday into Wednesday as
high pressure moves off the coast bringing warmer air into the
region. A rain/snow mix is possible inland going to all rain
Wednesday, and rain along the coast. Temperatures will be returning
to near normal levels Wednesday.

Finally another wave approaches to the west Wednesday night with a
warm front moving north Thursday. This system is expected to bring
mainly rain to the entire region, with some snow mixed in  well
inland late Wednesday night.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
A weak low pressure system passes to the south tonight otherwise
high pressure remains nearby throughout the TAF period.

VFR.

Low pressure moves off the Mid Atlantic coast to the south and cigs
lower some at southern most coastal terminals, however VFR will
prevail.

wind. Overnight the winds will be light and variable, especially

morning. The winds then become S into Friday afternoon, with coastal
terminals having a chance to get to 8-10 kt for a few hours late in
the afternoon, before the winds get under 5 kt again Friday evening.

     NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
