An area of low pressure from the Midwest passed west of Southern New England and into Canada, swinging a cold front through New England during the night of November 18 and morning of November 19. Strong west winds trailed the cold front and brought scattered reports of damage.

Area Forecast Discussion
National Weather Service Taunton MA
103 PM EST Sun Nov 19 2017
.SYNOPSIS...
Strengthening low pressure over western NY state at predawn
continues to intensify as it moves across northern New England
this afternoon. Its attending cold front sweeps through the
region late this morning into early afternoon. Behind the front,
the mild air will be replaced by much colder weather on
blustery west winds this afternoon into Monday. Winds shift to
southwest with milder temperatures on Tuesday, followed by a
cold front sweeping across the region that will bring showers
late Tuesday night and Wednesday morning. Dry and colder
conditions expected late Wednesday through the end of the week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1 PM update...
Cold front moving across the Cape and will move through ACK
between 1-2 pm. Skies are clearing behind the front, but sct-
bkn cu developing in the interior. W/NW gusts 35-45 mph will
continue with a few gusts to 50 mph over the higher terrain.
Sharp temp drop into the 40s will occur SE coastal MA and
Cape/Islands next few hours, otherwise temps will slowly fall
rest of SNE through the afternoon.
Previous discussion...
Showers within the left exit region of the upper jet moving
through RI and eastern MA and will exit the coast around midday
as dry slot overspreads the region. Clouds will give way to
increasing sunshine this afternoon.
Strong cold front in the CT valley will sweep across SNE this
morning, moving off the coast by early afternoon. The main
issue through the afternoon will be the strong wind gusts in
the strong cold advection with steepening low level lapse
rates. Soundings suggests most gusts in the 35-45 mph range, but
mixing to the top of the mixed layer supports peak gusts 40-45
kt so a few gusts up to 50 mph possible.
Strong CAA with 850 mb temps cooling to -4 to -8C by 00Z. Sharp
temp drop behind the cold front with temps falling into the 30s
in the interior high terrain, and mid 40s coastal plain by late
afternoon. With the gusty winds, it will feel considerably
colder.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
4 AM update...
Tonight...
Chilly night with good CAA as 850 mb temps drop to about -10C
by 12z Monday. Lows in the 30s with 20s inland but will feel
much colder given gusty WNW winds. Other issue will be potential
lake effect snow showers from NY state moving into western
MA/CT and possibly RI. All mesoscale guid advects low level
moisture from the lakes and steepening low level lapse rates
into the region. Will have to monitor later model trends to be
more specific on these potential mesoscale snow bands. For now
just inserted slight chance pops into the forecast.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
Highlights...
* Dry conditions and blustery NW winds Monday
* Moderating temperatures Tuesday into early Wednesday
* Dry but chilly for Thanksgiving day and Friday
Overview...
Overall progressive mid level pattern continues across North
America through most of the long term period, with a few fast
moving H5 short waves in the northern stream flow. There may be
scattered showers with milder temperatures ahead of the short
wave and surface frontal passages, followed by colder temps and
some gusty winds especially on Monday. May see some
amplification of the mid level flow across the eastern half of
the U.S. around mid week, which continues to show some signs of
model solution spread giving a bit lower confidence in timing
the surface front through. Models in better agreement in
bringing some southern stream moisture up the eastern seaboard
as cold front approaches around the Wednesday timeframe. The
front remains progressive, and should push offshore Wed night,
just in time for dry but cooler conditions for the Thanksgiving
day HS football games. Temps look to remain on the cool side at
the end of the week.
Details...
Monday into Tuesday...High confidence.
Another weak disturbance in the W-NW flow should remain dry but
will bring colder air across the region as it moves through the
northern extent of the large high pressure are settling across
the southern Appalachians and SE U.S. on Monday.
May see some lake effect snow shower streamers try to cross the
Berkshires into western areas, mainly near the E slopes and the
northern CT Valley especially late morning into the early
evening hours. At this point, should see only light activity.
Not expecting temps to recover much during the day with W-NW
winds gusting up to 30-40 mph, highest across the higher terrain
and east coastal areas through midday, then should slowly
diminish. Excellent cold air advection with H85 temps down to
-10C to -12C through midday with little change in the afternoon.
Expect highs only in the lower-mid 30s across the higher
terrain ranging to the lower 40s along the immediate coast.
NW flow early Tuesday will back to SW as the large high
pressure center shifts E during the day. Will see return of
milder temps as readings top off in the mid 40s to mid 50s, with
a few upper 50 degree readings possible across S coastal areas.
A cold front will approach late in the day but will remain dry.
Tuesday night and Wednesday...Moderate confidence.
Expect the cold front to push quickly across, but most of the
energy and moisture will remain across northern New England into
southern Quebec. Good pressure gradient sets up between the
high exiting to the E and the approaching front. Plus, models
continue to signal moisture working up the eastern seaboard from
developing southern stream mid level system across S GA/FL into
the eastern Gulf of Mexico.
Still some timing issues amongst the model suite, but showing a
bit better continuity in bringing precip across most areas
except N central and NW Mass Tue night, then will push E Wed.
May see a decent shot of QPF amounts during Wed as the moisture
feed moves across eastern areas with 0.2 to 0.3 inches possible
before ending. Kept CHC POPs going, with best chances across S
coastal areas. High temps Wed will top off a few degrees either
side of seasonal normals.
Winds shift to W as the front exits late Wed into Wed night,
bringing yet another shot of colder air from central Canada.
Thanksgiving and Friday...Moderate to high confidence.
High pressure sets up from New England southwestward through
the Ohio Valley into the mid Mississippi Valley by midday
Thanksgiving day, then slowly shifts S Thu night and Friday.
Models trying to bring another low toward the region from
Manitoba and western Ontario late Friday, but model solution
spread on timing and track of this system. Have kept a dry but
cold forecast going through Black Friday.
