Synopsis
Arctic airmass and dangerously cold wind chills continue
overnight and during the Tuesday morning rush hour. Temperatures
then moderate during Tuesday. Much milder air moves in
Wednesday into Thursday. An approaching frontal system will
bring occasional rain Wednesday afternoon into Wednesday night
with a period of heavy rain possible on Thursday. Mainly dry and
more seasonable temperatures Friday then turning much colder
Saturday. Snow showers are possible Sunday as another front
approaches.

Near term until 6 am Tuesday morning
Closed upper low moves off through the maritimes overnight. High
pressure approaches from the great lakes. This maintains a
pressure gradient over new england that supports strong
northwest winds overnight. Some cold air moves off overnight,
but enough CAA lingers to maintain strong gusts until sunrise.

Snow bands over outer CAPE cod have maintained during the early
night. Expect the snow showers to persist much of the night in
this area as cold air continues to move across the waters.

Continue forecast of min temps 7f to -7f. Wind chills continued
in double figures as of 10 pm, and should maintain in double
figures overnight... 15f to -20f, which is low enough to
maintain wind chill headlines.

Short term 6 am Tuesday morning through Tuesday night
4 pm update...

Tuesday...

frigid again tomorrow morning along with bitterly cold wind
chills. However not nearly as cold as today especially during
the afternoon as airmass modifies and winds slacken in response
to high pressure building in from the west. Highs actually
manage to get into the low and mid 20s along with sunshine.

Tuesday night...

with high pressure overhead and a very dry airmass in place
temps will freefall during the evening. Therefore followed the
colder MOS temps. Expect temps to level off second half of the
night as ssw pgrad increases along with mid high clouds
approaching from the west.

Long term Wednesday through Monday
Highlights...

* rain Wed aftn night possible starting as snow mixed precip interior
* a period of heavy rain thu, especially SE new eng
* mainly dry and turning colder Fri into sat
* snow showers possible next Sunday
Wednesday...

increasing warm advection in SW flow combined with deepening
moisture plume moving into sne will bring rain to sne, mainly
during Wed afternoon. The column is marginally cold enough for some
snow sleet at the onset across the interior, but this should be
short lived as increasing SW flow rapidly warms the boundary layer.

Temps moderate into the upper 30s to mid 40s during the afternoon.

Modest low level jet develops across the coastal plain and soundings
show enough bl mixing to support gusts to 35 mph SE new eng.

Wednesday night into Thursday...

good heavy rain signal late Wed night Thu as low level jet advects
anomalous pwats into sne. Pwat and low level wind anomalies are 3sd
above normal. Widespread rain expected Wed night with heaviest rain
likely during Thu as axis of low level jet and frontal wave enhances
convergence along the boundary. Some elevated instability so
also can't rule out some convection across SE new eng. Expect
widespread rainfall 1 to 2 inches, with risk of localized 3 inch
amounts across ri and SE ma which will result in areas of urban
and poor drainage flooding. 70-80 kt low level jet develops across
se new eng on thu. Soundings show a good low level inversion which
will limit these gusts from reaching the surface but still potential
for gusts reaching advisory criteria across SE new eng.

Friday into Sunday...

deep trough sets up across eastern canada as piece of polar vortex
rotates south from hudson bay with dominant northern stream across
new eng. Blustery and seasonably cold fri, then secondary front
delivers modified arctic air for Fri night Sat with below normal
temps. Mainly dry Fri Sat although some higher elevation flurries
possible at times as series of shortwaves rotate through. Higher
risk of snow showers Sunday associated with a stronger shortwave
and more moisture as onshore flow develops.

Monday...

low confidence given lots of spread in upper air pattern. Followed
wpc guidance with continued chance of snow rain showers.

Aviation 03z Tuesday through Saturday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday night ... High confidence
overnight...

scattered snow showers and localized MVFR across eastern ma will
end after 06z with partial clearing andVFR. Otherwise, MVFR
should be confined to the outer CAPE in snow showers with snow
accumulations ranging from a coating to 2 inches. ElsewhereVFR
with gusty wnw winds becoming more nnw with gusts up to 30 kt,
highest over the CAPE and islands.

Tuesday... .

MVFR CIGS continue across the outer cape. OtherwiseVFR prevails
along with nnw winds 20-30 kt.

Tuesday night...

winds finally diminish.VFR with low risk of MVFR and precip
exiting eastern ny into western new england. Brief period of a
wintry mix possible but likely holding off until Wednesday.

Kbos terminal... High confidence in taf.

Kbdl terminal... High confidence in taf
outlook Wednesday through Saturday ...

Wednesday: MVFR ifr conditions possible. Windy with gusts to
30 kt. Chance ra, fzra.

Wednesday night: mainly MVFR, with areas ifr possible. Windy
with gusts to 35 kt. Ra.

Thursday: mainly MVFR, with areas ifr possible. Strong winds
with areas gusts to 45 kt. Ra, chance fzra.

Thursday night: mainlyVFR, with local ifr possible. Breezy.

Slight chance shra, slight chance shsn.

Marine
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday night ...

*** heavy freezing spray warning ***
*** gale warnings continue ***
overnight...

frigid airmass continues to overspread the waters via wnw gales
that become nnw overnight. Heavy freezing spray warning eastern
ma waters, freezing spray advisory elsewhere. Snow showers limit
vsby to about 1 mile at times.

Tuesday...

nnw gales likely in the morning along with moderate to heavy
freezing spray. But improving during the afternoon as temps not
as cold and wind eases as well.

Tuesday night...

light winds as high pres builds over the waters. No headlines
expected.

Outlook Wednesday through Saturday ...

Wednesday: low risk for gale force winds with gusts up to
35 kt. Areas of rough seas. Chance of rain.

Wednesday night: low risk for gale force winds with gusts up to
35 kt. Rough seas up to 11 ft. Rain likely.
