The episode as NWS BOX wrote it up.
Matthew was a major hurricane in the Caribbean and Bahamas, then weakened along the Southeast US coast and became post-tropical off North Carolina. The remnants of Matthew merged with a cold front off the coast and moved past Cape Cod during the night of October 9th-10th. This caused wind damage in parts of Eastern Massachusetts.

Area Forecast Discussion
National Weather Service Taunton MA
408 PM EDT Sun Oct 9 2016
.SYNOPSIS...
Rain lingers across the region through the evening, ending from
west to east. Gusty winds expected overnight into tomorrow. High
pressure then builds over the region with dry weather and
seasonable temperatures through most of next week. The exception
to that may be Thursday, when a cold front should cross our
region.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
Models continue to struggle, even during the event with mod-hvy
rainfall across much of the region. At odds is the very dynamic
negative trof and tropical interaction, something models typically
struggle with. In spite of continued dry/cool air entrainment from
the N, bands of rain will linger well into the evening especially
across the E as strong inverted trof continues to develop and
stretch across the remainder of the forecast area it has not
currently hit. Final totals (thanks to PWATS near 2.0 inches) will
range form about 0.25 inches NW to near-above 2.00 inches across
the Cape/Islands. Many locations will see a much appreciated
1.00-2.00 inches.
This evening and overnight, expect precip to gradually dissipate
from W-E as strong subsidence forms behind the inverted trof. It
may take until the early morning hours to fully clear the
Cape/Islands, while it ends after dark further inland. The colder
air moving in, combined with strong pres gradient (more on that
below) will lead to rapid cooling as precip ends, with some
locations dipping into the upper 30s while the remainder of the
area sits in the low-mid 40s by early AM. The areas closest to
reaching frost-potential are across NW MA where the growing season
has already come to an end.
The other issue will be increasing N winds. Strong 1030+ high pres
will meet low pres remnants of Matthew offshore, which may deepen
thanks to continued ET process and strong negative trof. This
generates a very strong pres gradient and very tight isallobaric
couplet through much of the overnight hours. Winds aloft at H92
hover near 45 kt, so given these factors winds, especially along
the SE coast where all of these are maximized may reach 40-50 mph
at times. Will hoist a wind advisory for the Cape/Islands, but
this may need to be expanded further inland. Interior winds mainly
gust 30-40 mph at peak due to lackluster of mixing.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
Tomorrow...
Winds will continue blustery through much of the day thanks to an
increase in BL mixing with sunrise. Otherwise, highs likely to
overachieve by a bit thanks to slight downslope component late and
H92 temps dropping through the day. Looking at highs in the upper
50s to low 60s, but with a cooler feel due to the winds. Ocean
effect clouds may linger across the Cape, thanks to the N
component to the flow and temp differential approaching 12C
between SSTs and H85.
Tomorrow night...
In spite of the blustery start, pres gradient rapidly slackens as
high pres moves overhead. Dry column supports clear skies.
Radiational cooling with H92 temps starting around +4C should
allow for inversions dropping temps in the 30s. Most sheltered
valleys may once again see 32 or less particularly in the valleys
across W MA and CT, with temps very close to 32 in the lower
coastal plain as well. Although no watch issued with this update
due to the uncertainty, may need to monitor for freeze and frost
headlines by early Tue morning. Anyone with sensitive plants may
wish to take action early.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
Highlights...
* a Series of high pressures brings dry, near seasonable weather
most of this week
The forecast remains remarkably quiet through this portion of the
forecast. Our region will be under the influence of two high
pressures for much of this week. The first moves east from the
Maritimes mid week, with the second arriving from the west on
Friday.
Our only chance for more rainfall looks to be late Thursday into
Thursday evening. This is when a low pressure moving through Quebec
will bring a cold front through our region. The latest guidance
continues to highlight the lack of moisture with this front. It is
now appearing more likely this front will pass through with dry
weather for most of southern New England.
Temperatures will warm to seasonable or even above normal levels
through Thursday. The cold front moving through Thursday will drop
temperatures back below normal for Friday into next weekend.
&&
.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
Forecaster Confidence Levels.
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Short Term /through Monday Night/...
Through 06Z overnight...High confidence in trends, lower
confidence in exact timing.
VFR conditions already in the CT valley and slowly moving E.
Expect this trend to continue as IFR/MVFR sites gradually improve
through the afternoon and evening. Timing within a couple of hours
of TAFs, Cape/Islands may remain MVFR into early tomorrow morning.
N-NE winds increasing through the afternoon, with gusts around
30-40 kt at times near shore during the overnight hours. 20-30 kt
inland.
Tomorrow and tomorrow night...High confidence.
VFR. Main issue will be 20-35 kt wind gusts out of the N through
the daylight hours. These winds diminish rapidly overnight.
KBOS TAF...Mainly IFR through 00Z, gradual improvement through
04Z-06Z at which point expect mainly VFR. Wet runways until 03Z.
Winds increase through the afternoon...peaking overnight at 25 to
35 kt.
KBDL TAF...Mainly VFR from now on as rain comes to an end.
Outlook /Tuesday through Friday/...
High confidence. VFR. Low risk for IFR or MVFR conditions in fog or
marine stratus Wednesday night into Thursday morning.
&&
.MARINE...
Forecaster Confidence Levels.
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Through the overnight hours...High confidence.
Winds will gradually increase out of the N through the overnight.
Gusts 40-48 kt are expected except for the more sheltered
Narragansett Bay and Boston Harbor. Will extend the current Gale
warnings well into the day tomorrow as it will likely take some
time for winds to fully decline especially across the E waters.
Small crafts for the aforementioned Bay/Harbor. Low risk for near
storm force gusts. Seas gradually build, reaching nearly 12 ft by
early tomorrow morning on the SE ocean waters.
Tomorrow and tomorrow night...High confidence.
Winds subside but remain above small craft thresholds into the
overnight. Gales will likely be converted to small craft
advisories through the day. Seas remain elevated although will
begin to decline. Lowest heights will be around 8 ft on the ocean
waters by sunrise Tue.
Outlook /Tuesday through Friday/...Moderate confidence.
Winds diminish Tuesday in Tuesday night as a high pressure builds
over the waters. Winds increase once more Thursday night into
Friday as colder moves over the waters behind a cold front.
The more significant issue is how quickly seas will subside,
especially across the outer coastal waters. Matthew and Nicole have
generated a lot of southeast swell, which should be impacting the
outer coastal waters all of this week. Small craft advisories may be
necessary for a portion of this time, particularly on the outer
waters.
