Synopsis
Deep low pressure moves over the canadian maritimes through this
evening. Arctic high pressure builds into the region tonight into
Tuesday, then quickly shifts offshore Tuesday night ahead of an
approaching frontal system. The frontal system will impact the
area Wednesday into Thursday night. High pressure builds briefly
Friday into Saturday. Another frontal system will be possible
late in the weekend.

Near term until 6 pm this evening
Anomalously deep upper level low will move over new england this
afternoon continuing to usher in the coldest air of the winter
season so far. While this air mass is of arctic origins, record
lows for january 21 were all below zero set back in 1985 at
most climate sites. Record min high temperatures were also set
back in 1985 and in the single digits.

Temperatures early this morning will generally be near 0 across
the interior and middle and upper single digits elsewhere.

Blustery NW winds will make for wind chills this morning -15 to
around -20 across connecticut, the lower hudson valley and w
passaic and W bergen counties in nj. The wind chill advisory
remains in effect for these locations until 18z. Elsewhere, wind
chills will range from -10 to -14, but it would not be out of
the question a few isolated spots touch -15. An sps has been
issued for our nyc, long island, and the rest of NE nj zones to
address the wind chills outside of the advisory area.

Temperatures will rise into the low and middle teens by afternoon,
which should allow wind chills to fall below wind advisory criteria,
but still very low from around -5 to -12.

The other story today will be the strong winds. Sustained winds 20
to 30 mph with gusts 35 to 40 mph should prevail, but gusts could be
as high as 50 mph at times. Winds should begin to weaken this
evening especially after sunset.

Moisture profiles in the 00z models show a good deal of middle level
moisture as the upper low passes. Mostly cloudy skies are expected
to develop this morning, continuing into the afternoon.

Skies will begin clearing from west to east this evening. With
the passage of a strong vort MAX with the upper low, a few
flurries and snow showers have been reported across the interior
of southern connecticut. Until the vort passes to the east by
this afternoon a few flurries and snow showers will be possible
and these were added to the forecast.

Short term 6 pm this evening through 6 pm Tuesday
Cold advection weakens significantly tonight as the upper low moves
well offshore and heights build aloft. Winds will gradually weaken
through the night as arctic high pressure builds over the northeast.

The arctic high will still keep very cold conditions tonight with
lows ranging from around zero inland to the single digits most
elsewhere. Wind chills should stay below advisory criteria, -5 to
-10. These wind chills occur early in the night since that is when
the strongest winds are anticipated. Wind chills should generally be
0 to -10 around day break Tuesday.

High pressure remains in control on Tuesday with ridging aloft.

Temperatures moderate into the middle and upper 20s for highs. Winds
will be light with the high pressure over the region which allow
wind chills to be near actual temperatures.

Long term Tuesday night through Sunday
An active long term period will be setting up as a eastern ridge
moves into the western atlantic Tuesday night into Wednesday, and
then a deep longwave trough will predominate across much of the
eastern united states into early next week. A series of shortwaves
will move through the longwave trough. Timing and placement of these
embedded shortwaves will become more uncertain in the longer term.

The first wave to impact the region will be moving into the plains
states Monday night into Tuesday. And by the time the low pressure
system moves into the great lakes Wednesday, differences emerge in
the timing of this low. However, the low will be moving inland and
warm advection ahead of the system will bring mostly liquid
precipitation to the region. Depending on the timing the
precipitation may begin as light snow and, possibly a wintry mix
Wednesday morning, then as the warm air quickly moves north the
precipitation transitions to rain. With a deep moisture feed from
the gulf of mexico and the atlantic, and a slow progression of the
system, a heavy rainfall is becoming more likely. As this system
departs additional energy rotates into the upper trough for late
Friday into Saturday. At this time the remains a lot of uncertainty
with the strength, placement and timing. For now will have just
slight chance probabilities for snow showers Friday night.

Another system, a weak clipper, may move through the northern stream
Saturday night. With the deep eastern trough still remaining into
the end of next weekend and into the beginning of next week, yet
another low pressure system may impact the region Sunday into next
Monday, although confidence in any potential impacts or track at
this time remains low.

Aviation 15z Monday through Friday
Low pressure tracks into the canadian maritime provinces today as
canadian high pressure builds in from the great lakes.

Vfr through the TAF period, but with sct-bkn CIGS around
3500-5000 ft.

Nw flow with gusts increasing to 35-40kt by this afternoon.

Winds begin to gradually diminish by early evening, but should
remain gusty through the overnight hours.

Ny metro enhanced aviation weather support...
