Area Forecast Discussion
National Weather Service Boston/Norton MA
247 PM EST Thu Nov 21 2019

.SYNOPSIS...
High pressure will settle over Southern New England today with
mostly sunny and seasonable weather conditions. Mild and gusty
Friday as a cold front swings through New England. Colder air
moves in behind the front Friday night. Weak high pressure
brings dry weather Saturday. Low pressure moving up from the
Gulf of Mexico will bring rain to much of our area late Saturday
night and Sunday. Portions of Northwest MA may start as mix of
snow/sleet/freezing rain before changing to rain. High pressure
brings drier weather Sunday night through Tuesday. A cold front
may bring showers Wednesday, followed by dry weather again for
Thanksgiving.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1030 AM Update: No significant changes.

Gorgeous weather today with high temperatures topping out at around
50 for most areas this afternoon, which is just about where we
should be this time of the year. Might be a couple of degrees
cooler in the higher elevations and a couple of degrees warmer
in the CT River valley. Lingering clouds on Cape Cod and
Nantucket from northerly flow will diminish by mid afternoon,
leaving plenty of sunshine across all of SNE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
Tonight:

Mid/upper ridge axis builds into the waters east of Cape Cod by
tonight, and a low-level SW jet 35-40 kts encourages warm and moist
advection to increase in earnest as we move into the evening.

Several guidance sources especially into the eastern Berks/Pioneer
and CT Valleys were indicating some light QPF in the warm advection
regime tonight. Model forecast soundings however show dry low-levels
with what looks like mid-level clouds, so have opted to keep the
forecast dry until top-down saturation can complete - mainly early
in the day on Friday.

850 mb temperatures warm given the thermal advective pattern into
the +2 to +5C range by 12z Friday. Given this, and light SW winds 5-
10 mph overnight and the increase in clouds, opted for early lows in
the 30s before temperatures show a non-diurnal temperature increase,
with temps by daybreak Friday into the upper 30s to mid 40s areawide.

Friday:

Partly to mostly cloudy conditions, though with somewhat mild and
breezy southwesterly warm-sector conditions should exist early into
Friday. We will then await a strong upper-level disturbance and
associated strong surface cold front moving in from the eastern
Great Lakes/western NY for the afternoon. A strong shot of colder
air is expected to overspread the area during the second half of
Friday with the front's passage, resulting in sharply falling late-
afternoon temperatures and developing breezy to gusty NW winds both
over the land and especially out on the waters.

Pre-frontal, opted to raise temperatures into the mid to upper 50s
away from elevation, given some benefit from southwest downsloping
with 850 mb temps in the +5 to +7C range. Could see some spots reach
60 but would take more peeks of sun that look plausible at this
point. Should see some southwest breezes with gusts to 20-25 mph
limited by shallow mixing/progged inversion.

Seems that most model guidance supports progressing the front
into our western counties by around 16-18z, then racing quickly
towards the coast and offshore by around 22-00z. Did note models
were somewhat wetter with forecast QPF, but think limited
moisture to work with and the fast forward speed makes for this
being a low-QPF frontal passage (a few hundredths to a tenth at
most). Once the front clears, strong cold advection (850 mb
temps will plunge to values -6 to -9C across the CWA) will
steepen lapse rates considerably and encourage gusty NW/WNW
winds to develop across land areas by the late afternoon, with a
good likelihood of gale conditions across most waters. Should
see sub-Wind Advisory northwest wind gusts 30-35 mph with up to
40 mph possible, with falling temps into the 30s producing some
wind chills down into the 20s by early Friday evening in
northern Worcester County and the Pioneer Valley.

.LONG TERM /SATURDAY THROUGH THURSDAY/...

Upper flow is initially split between northern and southern
branches. But this evolves by Sunday to a single jet moving through
a broad trough centered over North America. Five-wave scale starts
with a trough over the Eastern USA and a ridge over the West Coast.
The pattern shift west by next week with the five-wave trough over
the Rockies and a West Atlantic ridge backing toward the USA East
coast.

Heights at 500 mb vary during the period, dropping below normal as
east storm moves through, then climbing into the 550s Dm in between.
Overall expect the deep layer to reflect near normal temperatures,
except colder temps Saturday night and Sunday as a coastal storm
moves past.

Confidence is low-moderate Saturday night-Sunday with the coastal
storm and Wednesday with timing of a midweek cold front. Higher
confidence with the dry weather in between.

Daily Concerns...

Saturday...

Shortwave ridge over the region will provide plenty of subsidence
and dry weather. Increasing high level moisture moves into CT and
Western MA late in the day, so expect increasing high thin clouds at
that time. Mixed layer reaches to about 950 mb, with layer temps
supporting surfce max temps in the 40s.

Saturday night-Sunday...

Weather system coming out of the Gulf will draw moisture north to
New England while pulling colder air south from Canada. The
combination of these factors brings wet weather to our area Saturday
night and Sunday. The question is how much of the northern stream
colder air is drawn over Southern New England. There is no sign of a
Maritime high or other source of cold air damming, and no sign of
other souces of cold air drainage. The projected track of the storm
has the center moving up along the South Coast, farther north than
models showed yesterday and suggesting warmer temperatures farther
inland. For now the forecast favors mainly rain, except some
snow/sleet in NW Mass that changes to rain by midday Sunday.

Monday through Thanksgiving Day...

High pressure brings dry weather Monday and Tuesday. Mixed layer
reaches to 925 mb, where temps will be 0-2C Monday and 3-5C Tuesday.
Mixing of those temps to the surface supports max sfc temps in the
40s Monday and lower 50s Tuesday.

A cold front swings through on Wednesday. Current model timing of
the cold front is faster than yesterday by 6 to 12 hours. Such run-
to-run changes lowers confidence in this timing. Moisture in the
column will be limited, so expect scattered showers along and just
ahead of the front. Enough of a gradient and cold advection to bring
west-northwest gusts to 35 mph Wednesday afternoon and Thursday.

One other note: We are coming into a period of high astronomical
tides Sunday and Monday. Depending on the wind direction and timing
of highest surge, a worst case scenario would bring some minor
coastal flooding with the Sunday high tide on either coastline (5.7
ft MLLW at Providence at 541 AM, 11.2 ft MLLW at Boston at 845 AM,
and 3.9 ft MLLW at Nantucket at 946 AM). Ensemble guidance from
Stevens Institute shows a potential surge of 1.0 to 1.5 ft. Tides
are a little higher Monday morning, but by then we should be dealing
with offshore (west) flow which should limit the threat.

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
Forecaster Confidence Levels...

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Short Term /through Friday Night/...High confidence.

18z TAF Update:

This afternoon:

Leftover MVFR CIGS on Cape Cod and Nantucket will diminish by
20Z as N winds gradually subside. Otherwise VFR with N winds
backing to W/SW this afternoon.

Tonight:

VFR conditions with increasing cloudiness overnight. Southwest
winds 5-10 kts, though increasing SWly low-level jet of 35-40
kts could produce pockets of low-level wind shear/turbulence
late tonight into early Friday.

Friday:

Continued lowering to ceilings, but should remain at VFR levels
ahead of a cold front. Southwest winds 10-15 kts with gusts up
to 25 kts through early afternoon ahead of the cold front; a
brief period of MVFR and scattered showers will accompany the
front before a wind shift to NW by late afternoon. NW winds
25-30 kts with gusts of 35-40 kts after 21z.

KBOS TAF...High confidence in TAF.

KBDL TAF...High confidence in TAF.

Outlook /Saturday through Tuesday/...

Saturday: VFR. Breezy.

Saturday Night: Mainly VFR, with local IFR possible after
midnight. RA likely, chance FZRA in Western MA.

Sunday: Mainly MVFR, with areas IFR possible. Windy with local
gusts up to 30 kt. RA likely, FZRA likely in Western MA.

Sunday Night: Mainly VFR, with local IFR possible. Breezy.
Slight chance SHRA, slight chance SHSN.

Monday: VFR. Breezy.

Monday Night through Tuesday: VFR.

.MARINE...
Short Term /through Friday Night/...Moderate confidence.

Extended the small craft advisory for Nantucket Sound to 3pm
because of 25 kt wind gusts. Otherwise, winds should then
slacken from west to east. Small craft advisories also remain in
effect for most offshore waters and Cape Cod Bay into the
afternoon.

Seas will tend to slowly subside through tonight with easing
winds. The bigger concern for mariners is the cold frontal
passage late Friday, expected to bring a period of gale-force
WNW winds across the the coastal and outer waters, with the
possibility of low-end gales into Boston Harbor and Narragansett
Bay. Have therefore hoisted Gale Watches from late Friday
afternoon through early Saturday morning.

Today: NW winds 10-15 kts with gusts 20-25 kts early to decrease
to 5-10 kts by afternoon. Seas 4-7 ft outer offshore waters,
though will tend to lower as the day progresses. Good
visibility.

Tonight: Winds become WSW and increase to 10-15 kts with gusts
to 20 kts by daybreak Friday. Seas mainly 2-4 ft, though with
leftover 5 footers early. Good visibility.

Friday: WSW winds continue to increase to low-end SCA levels
(mainly 15-20 kts with gusts to 30 kts) ahead of a cold front
expected to cross the waters late Friday. Wind shift to NW with
20-25 kt winds, gusts 35-40 kts, tending on the lower end of
that range in the bays and harbors. Seas build to 5-9 ft,
highest southern and southeastern waters. Light showers could
bring visibilities down to 4-6 miles late Friday afternoon with
FROPA.

Outlook /Saturday through Tuesday/...

Saturday: Low risk for Small Craft Advisory winds with gusts up
to 30 kt. Local rough seas.

Saturday Night: Winds less than 25 kt. Rain likely.

Sunday: Low risk for Small Craft Advisory winds with gusts up
to 30 kt. Local rough seas. Rain.

Sunday Night: Moderate risk for Small Craft Advisory winds with
gusts up to 25 kt. Areas of rough seas. Slight chance of rain
showers.

Monday: Winds less than 25 kt. Local rough seas.

Monday Night through Tuesday: Winds less than 25 kt.
