Synopsis
Some light precipitation is expected today and tonight. Most of it
will be rain, but light icing is likely over interior high terrain
especially tonight into early Tuesday. A fast moving storm system
will bring a period of heavy rain to the region Tuesday along with
strong winds across SE new england. Blustery, dry and colder weather
follows Wednesday through Friday, then a warming trend next weekend.

A cold front may bring showers by next Sunday.

Near term until 6 am this morning
1040 pm update...

leading edge of overrunning precip pushing into the berkshires
and litchfield hills as seen on latest NE regional 88d radar
imagery, though not seeing any ground truth of it reaching the
ground yet. Have kept slight chc pops going for now from around
midnight onward, but will monitor the precip progression.

T TD spreads are lower, down to 4 degrees or less across the ct
valley with some patchy fog from about kpsf-kore and northward
into S vt S nh on 03z obs. As lower layer continues to moisten,
will likely see more patchy fog develop so have included that in
the overnight forecast.

The temps were mainly near or below freezing across N central
and W mass at 03z, so will likely see some mixture at the onset
of the precip but should be very light at least to start. Will
follow suggestion from previous shift and issued special weather
statements as needed.

Remainder of forecast was updated to bring conditions current.

Previous discussion...

high pressure is situated to provide dry weather much of the
night. Low level flow remains light most of this time, but shows
signs of overrunning after midnight. Meanwhile, satellite images
and sfc observations show a cloud deck over eastern pa edging
northeast. Between this and the favorable development of lift
overnight, expect increasing clouds through the night.

Can not rule out some light precip late, especially in western
ma and ct, but the chance before 12z is rather low so we used
slight chance pops. If any precipitation were to form late
tonight, temperature profiles suggest rain in the south and a
snow sleet freezing rain mix north.

Clouds will limit the overnight cooling, and cold air damming
signal does not show much until late night. We maintain a range
of upper 20s north to mid 30s south coast.

Short term 6 am this morning through 6 pm Tuesday
Monday...

high pressure over quebec Monday and increasing cold air
damming into new england. The damming seems focused on northern
new england, but could further expand into our area as well
during Monday morning. Our temperature profiles support rain
most places, but a rain snow mix north of the mass pike.

The GFS and ECMWF bring a front south into southern new england
or just to our south. This shows increasing lift potential, thus
increasing pops. We show chance pops all areas Monday morning
and likely pops in the afternoon in western and central mass and
adjoining ct. An east wind should be enough to keep ptype as
rain, but it may be marginal in western mass northern worcester
county.

Even with better lift, the focus of southerly low level winds
and moisture remains to our west across new york state through
the day. So we continue to expect QPF amounts up to 0.1 inches.

Monday night...

evening cooling and the stalled front to our south may allow a
brief period of freezing rain in central and western mass,
especially along and north of the route 2 corridor. The front
moves north during the night with winds shifting from the south.

This will bring slowly rising temperatures overnight ending the
icing risk.

South-southwest winds 35-40 knots move up over the region during
the late night. This transports 1 inch pw values into the area.

Expect increasing chance of rain toward morning with
categorical pops... 75 pct or higher... Over western mass and
western ct.

Long term Tuesday night through Sunday
Highlights...

* blustery and colder wed, and especially Thu fri, but dry
* much milder next weekend with showers possible by Sunday
Tuesday night...

cold front will be in the vicinity of the CAPE islands Tue evening
then moving offshore. Some lingering showers are possible here
early, and a few rain to snow showers possible western ma in the
evening as mid level trough swings through. Otherwise, gradual
clearing will develop although some lower clouds may linger across
nw ma. Gusty west winds will develop overnight as low level cold
advection increases.

Wednesday through Friday...

blustery and colder pattern as longwave trough develops over the ne
but mainly dry weather expected with dry column and subsidence. Near
normal temps wed, then trending below normal Thu fri. Core of the
coldest air aloft on Thu with 850 mb temps near -15c. This will
result in highs Thu mainly in the 20s to near 30 with gusty winds
making it feel considerably colder, while Thu night wind chills drop
into the single numbers and subzero higher terrain. Temps recover
fri as heights begin to rise and low level temps moderate but a cold
start will hold temps from the upper 20s to mid 30s.

Saturday and Sunday...

return to milder airmass and well above normal temps as high pres
moves offshore and mid level ridge builds north along the east
coast. 850 mb temp anomalies 1-2sd and eps GEFS ensembles have
fairly high probs of 50s in the coastal plain by sun. Deterministic
gfs looks too fast with next approaching trough and not supported by
majority of GEFS members so we leaned toward slower ecwmf solution
given downstream ridging in place over the western atlantic. Next
chance of showers assocd with the mid level trough and attending
cold front should hold off until Sunday or possibly Sat night. Very
low risk of some icing distant interior if precip comes in Sat night
but any freezing precip would probably be localized and this is
a very low probability.

Aviation 08z Monday through Friday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday ...

overnight... High confidence.

MainlyVFR conditions with light variable winds becoming S along
the S coast toward daybreak. Expect CIGS vsbys lowering to MVFR
across the E slopes of the berkshires and ct valley by around
05z, then will slowly shift E across central and NE mass. Will
see a spotty light mix of -ra -sn -fzra -pe mainly across the e
slopes of the berkshires to N worcester county and the
merrimack valley through daybreak.

Monday... Moderate confidence.

MVFR CIGS with areas of ifr CIGS developing in the afternoon.

Increasing chance of light rain through the day. Generally MVFR
vsbys in rain and some mixed rain snow. Light wind becomes light
east-northeast.

Monday night... Moderate confidence.

MVFR conditions with areas of ifr. Rain most places with a
chance of freezing rain early in northern areas of massachusetts
such as vicinity of fit and ore. Winds turn from the southeast
and south toward morning.

Kbos terminal... Moderate to high confidence in taf.

Kbdl terminal... Moderate to high confidence in taf.
