Synopsis
Arctic high pressure will build in through Tuesday, then
quickly shift offshore Tuesday night ahead of an approaching
frontal system. The frontal system will impact the area
Wednesday into Thursday night. High pressure will build briefly
from 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 and set back in 1985 at
most climate sites. Record minimum high temperatures were also
set back in 1985, and were in the single digits.

Temperatures have not risen much today, and are only around 10
above in metro most coastal sections and in the single digits
elsewhere, in fact still close to zero in the northernmost
reaches of southern ct. Only expect temps to rise a few degrees
more, remaining in the single digits across interior southern
ct, and perhaps making it just over 15 above in and just outside
nyc.

Wind advy remains in effect for nyc metro and along the coast,
with NW winds gusting just over 45 mph at times. Wind chill advy
meanwhile remains in effect for most inland sections, where
lower sustained winds but colder air is still producing wind
chills of 15 below.

A few flurries or snow showers should persist over parts of
southern ct and eastern long island until a vort MAX on the back
side of the deep closed upper low over new england passes east.

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 17z Monday through Friday
Low pressure continues to depart through the canadian maritimes
today as canadian high pressure builds in from the great lakes,
settling over the region on Tuesday.

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

Nw flow with gusts 35-40kt this afternoon. Winds begin to
gradually diminish this evening, but will remain gusty into the
overnight hours. 10-15 kt winds by daybreak Tuesday will
continue to diminish into the afternoon, eventually shifting to
the wsw at 10 kt or less.
