Synopsis for massachusetts and rhode island coastal waters.. NW gradient persists along the E waters through this afternoon as gradually high pressure builds into the region. Exiting out ahead of nestor remnants which will sweep well S of new england around Sunday night, an accompanying breezy E wind is expected along with the possibility of rain. Blustery sw flow along with rain forecast ahead of a sweeping cold front around Tuesday night. High pressure and dry weather follows for the rest of the week. For information on possible hazardous weather beyond the 24-36 hour forecast period, please visit www.weather.gov/boston and follow the current hazards link above the map on the left.

Synopsis
High pressure and seasonable conditions through Sunday. Nestor
remnants tracking S of new england with the uncertain risk of
rain around Sunday night. High pressure builds in with dry weather
Monday, then a sweeping cold front will bring a period of showers
Tuesday afternoon into early Wednesday. High pressure follows late
in the week with seasonably mild temperatures and dry weather.

Another storm system may impact the region by Saturday but there is
much uncertainty.

Near term until 6 am Sunday morning
230 pm update...

a beautiful autumn day. Winds diminishing, comfortable conditions,
seasonable temperatures. Getting close to 60 in spots. Abundant
sunshine probably making it feel warmer. High pressure in control.

Tonight...

chilly, frosty. With high pressure, light winds, clear conditions,
it is a tad warmer today compared to yesterday, including dewpoints,
and it is a bit warmer aloft, the crux of colder air having pushed
off to the e. Thus leaning with persistence in the low temperature
forecast. Going with lows from the prior night but bumped them up
a couple of degrees. It's not perfect but feel it will be close to
actual. With the forecast no frost freeze headlines are required.

Short term 6 am Sunday morning through Sunday night
Sunday into Sunday night...

challenging rainfall forecast. Nestor remnants preceding weak h5-7
shortwave energy. An evaluation of frontogenesis, deformation, and
low-level moisture thetae, there's a n-draw along and around 300k
isentropic surfaces prior to mid-level synoptics and accompanying
trof axis. Squeeze out, the potential for mid-level outcomes.

However, heights rising out ahead of the n-plains cyclone across the
ne conus, strengthening surface high pressure, enhancing the wedge
of low-level drier air across the SE canadian maritimes brought by
the isallobaric wind component. NE flow undercutting over-running
mid-level outcomes. Two subsequent thoughts: 1.) nestor is nudged
further S to which latest 19.12z guidance has agreed upon despite
the disparity between global and high-res forecast guidance, and 2.)
that any outcomes, wherever they originate, may have difficulty in
getting to the surface, eroding before reaching the ground (virga).

Continued n-s spread of rainfall forecasts between model guidance
and individual ensemble members. For this forecast, will keep the
majority of pops (chance or greater) S of the ma-pike and reserve
likely pops for just nantucket and the waters s. Collaboration with
the nerfc, not going to go with the completely dry forecast. Prefer
to trend southward but allow later shifts to re-evaluate and make
adjustments as necessary. Avoiding a flip-flop given both the spread
and uncertain rainfall risk. Don't want to say completely dry only
to have to re-introduce rain later. Confidence is lacking. Light
rain thinking, not a wash-out.

Watching the undercutting E NE wind. With a nudge of nestor further
s, the stronger gradient should lie immediately offshore. Still
breezy for the s-coast, but the gales well out over the S waters.

Increasing clouds through the day. A bit mild tonight. Looking at
highs around the upper 50s to low 60s, lows into the 40s Sunday
night with the possible of quick cooling as clouds clear over N w
ma towards Monday morning.

Long term Monday through Saturday
Highlights...

* mainly dry and seasonable mon
* patchy drizzle Tue morning, then a period of showers late Tue into
early wed
* improving conditions Wed afternoon then dry and seasonably mild
thu fri
Monday...

remnants of nestor south of the benchmark and drifts eastward as
surface ridging in place across new eng. Deep moisture mostly
offshore by Mon morning so only a low risk of a lingering shower
over ack early, otherwise expect a mostly sunny day as column is
rather dry. Highs should reach low mid 60s with NE flow, which may
be gusty over the islands.

Tuesday into Wednesday...

persistent NE flow into Tuesday will result in considerable low
level moisture developing later Mon night onward with low clouds
overspreading the region by Tue morning. Models are indicating some
light QPF which will likely be in the form of drizzle given dry air
in the mid levels. By later Tue and especially Tue night moisture
deepens ahead of mid level shortwave and approaching cold front.

Expect a band of showers sweeping through sne late Tue into tue
night with potential for some heavier rain elements as higher pwats
advect into region with frontal wave possibly developing which would
enhance low level convergence. Model guidance differs on timing of
the front which will impact how quickly it clears out on wed. Ecmwf
is slower with showers lingering into Wed morning, especially
eastern new eng while GFS is more progressive. Leaning toward slower
solution given consensus of global guidance but expect improving
conditions during Wed with increasing sunshine developing from west
to east with seasonable temps.

Thursday into Saturday...

high pres in control south of new eng Thu with dry weather and mild
temps, possibly well into the 60s. Then forecast confidence
decreases Fri into Sat as models show significant differences on
evolution and timing of next upstream trough. Complex pattern with
possible interaction of multiple shortwaves. Dry weather should hang
on for Fri with seasonably mild temps, then low confidence into sat.

Gfs is wet Fri night Sat while ECMWF is dry with rain delayed until
sun. Have chance pops for Fri night into Sat given eps indicating
moderate QPF probs.

High - greater than 60 percent.

Short term through Sunday night ...

230 pm update...

rest of today... High confidence.

Nw gradient winds continuing to diminish. Around 5 to 10 kts at
this point, becoming variable, some immediate shore sea-breezes
have emerged along E ma coast. However, a decent W wind has
emerged along the s-coast around 10 to 15 kts. It too should
diminish towards evening with building high pressure. Seas less
than 5 feet. Clear conditions. Dry.

Tonight... High confidence.

Light winds around 5 to 10 kts diminishing to variable. Seas
less than 5 feet. Clear conditions. Dry.

Sunday into Sunday night... Moderate confidence.

Majority of wind and wave impacts over the S SE waters.

Light winds initially increasing out of the E to around 10 to 15
kts especially over the S SE waters as remnants of nestor approach,
15 to 20 kts with gusts up to 30 kts overnight into Monday morning.

Will keep waves below 5 feet even on the S waters mostly throughout,
increasing up to around by Monday morning for the S outer waters.

Chance to likely light rain during the overnight hours for the s
waters, however some uncertainty in the n-s gradient given nestor's
track.

Outlook Monday through Thursday ... Moderate confidence.

Monday: low risk for small craft advisory winds with gusts up
to 25 kt. Local rough seas.

Monday night: winds less than 25 kt. Areas of rough seas.

Slight chance of rain showers.

Tuesday: winds less than 25 kt. Rough seas up to 8 ft. Chance
of rain showers.
