What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Boston/Norton, MA wrote its last area forecast discussion before this river flood warning went out at Nov 9, 9:58 PM EST, 1 hour 14 minutes earlier.

Area forecast discussion, Nov 9, 9:58 PM EST, 1 hour 14 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
958 PM EST Fri Nov 9 2018

.SYNOPSIS...

An intensifying storm tracks over the the Cape Cod Canal tonight.
This system will bring moderate to heavy rains, potential flooding,
and possible strong to damaging winds. Dry and unseasonably chilly
temperatures follow Sunday into Monday. Another low pressure will
bring a period of heavy rain to the region late Monday night into
Tuesday, but there is a low risk for precipitation to begin as a
brief period of snow or ice across the interior. Dry but unseasonably
cold weather follows Wednesday into Thursday, before temperatures
moderate some by Friday.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...

10 pm update...

*/ Highlights...

 - Flood Watch trimmed to focus on E / SE New England into
   Saturday

 - Wind Advisory for Cape and Islands continues

 - Monitoring convection / heavy rain closely S of LI approaching
   SE New England, likely impacting shortly after midnight into
   early morning Saturday.

*/ Discussion...

Secondary low strengthening S of Long Island with observed pressure
falls around 2 mb / hr. Providing a localized convergent focus of
the warm-moist conveyor belt beneath broader diffluence aloft,
seeing heavy rain and convective elements emerge. Strong SW 0-6 km
shear and mean wind, line echo wave patterns emerging as discerned
via WSR-88D. MRMS interpreted 1-hour rainfall rates of 0.5 to 1.0
inch given the progressive nature of the storm system. Storm system
should lift NE through tonight at a rapid pace, exiting close to
early morning Saturday. Heavy rain and damaging wind threats continue
which are highlighted below.

WINDS ...

Focus ahead of the secondary low within the weak warm sector, marginal
lapse rates. A focus on H95 winds. Will hold with the present wind
advisory however there is some concern that even S areas of Bristol
and Plymouth Counties in MA could reach wind advisory criteria if
heavy rain is able to drag down faster momentum. S gusts upwards of
50 mph continue into early morning with the possibility of a quick
SW burst immediately behind the secondary low as both pressure
gradient and isallobaric forces advect colder air rearward allowing
steep lapse rates and that opportunity for a quick mix down of
faster momentum. Hence keeping the WIND ADVISORY for the Cape and
Islands extended through Saturday. GALE WARNINGS for all waters
throughout as well.

H95-925 SE jet centered around 1 am over SE New England, especially
Cape Cod and Islands with values over 55 to 65 mph. It'll be
interesting to see how much of this momentum will mix down to
the surface.

FLOODING ...

Significant WSR-88D radar returns approaching from the SE out ahead
of the secondary surface flow. Coupled pressure falls with anomalous
precipitable waters upwards of 1.5 - 1.7 inches per latest RAP / SPC
mesoanalysis, both the H925-85 moisture transport aimed at SE New
England, trimmed the FLOOD WATCH to SE New England highlighting the
region of greatest confidence for flooding rains. To the W, mid-
upper level drying along with subsidence between the double-barrel
low is contributing to a quick end to the rainfall over the NY
Hudson Valley extending into W New England. Collaboration with other
WFOs, watch was dropped W of the I-95 corridor.

Column saturation up to 12 kft per latest RAP, deep column ascent
given dynamics out ahead of the potential vorticity displacement
along the 1.5 PVU surface, potent vortmax and accompanying diffluence
aloft, undoubtedly some efficient rainfall production will occur
over SE New England.

Urban / poor drainage flooding, especially more so with leaf-clogged
drains. Potential flooding of faster responding small streams and
tributaries. Rivers running high as of late, so this water being
added to the system will only exacerbate and/or prolonged any
ongoing or forecast river flooding issues.

Quick 1 to 2 inches, locally higher amounts. Greatest amounts focused
in and around the Cape Cod Canal immediately E of the low track.

CONCLUDING REMARKS ...

With respect to emerging convection ahead of the secondary low, there
is some concern for localized severe weather. Can't rule out a brief
tornadic spin-up through the greater confidence is out over the warmer
waters further S/E. There's a lot of helicity in the region in addition
to low-level shear. If the lapse rates can steepen more than just
marginal, then the damaging wind potential greatly increases. Watching
closely for bowing segments within the line echoes that are approaching,
looking for any potential book-end vorticies that may emerge in the
NE quadrant of any bowing. Will handle any convective elements with
short-fused severe / special marine warning products.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...

Saturday...

*/ Highlights...

 - Wind Advisory for central/eastern MA and RI with Westerly gusts
   45 to 50 mph.

 - Flood Watch continues into Sat with the likelihood of some area
   rivers and streams continuing to rise in the wake of the Fri
   night rains

*/ Winds...

The low pulls rapidly northeastward and away from southern New
England during Saturday morning, steadily deepening along the
way. Negatively tilted upper trough sweeps thru southern
Quebec/northern New England with an associated short wave
pushing thru our area. This accompanied by cold air advection
and tight pressure gradient with departing low result in the
potential for a secondary W wind burst. Models show steep low
level lapse rates to H85/H7 which would enable mixing of
stronger winds aloft to the surface. Anticipating Wind Advisory
event over a portion of southern New England with gusts 40-45
kts. Have issued a Wind Advisory for RI and central/eastern MA
for Saturday 10 am to 7 pm.

*/ Precipitation / Flooding...

Could still have some patchy light rain lingering at daybreak,
possibly a light snow shower across the highest terrain of Franklin
County MA. Looking at model soundings, quite a dry airmass in
place but given steep low level lapse rates, can't rule out an
isolated shower or 2, or even a few flurries over the far
interior.

Otherwise mainly dry day in store. However Flood Watch continues
into Saturday, as some area rivers and streams will likely still
be rising from the very recent rains.

High temps for the day will probably occur in the morning for some
locales, especially eastern MA and RI. Temps falling in the
afternoon.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...

Highlights...

* Dry/unseasonably chilly Sun into Mon afternoon

* Period of heavy rain/renewed flooding concerns late Mon night/Tue
  with a low risk for a brief period of snow/ice at the onset across
  the interior

* Dry but unseasonably cold Wed/Thu with some moderation by Fri

Details...

Saturday night...

Dry, but breezy to windy weather will continue Sat night in the cold
air advection pattern.  Bufkit soundings continues to support
excellent mixing...so 25 to 40 mph wind gusts will continue well
into the evening.  Low temps will bottom out mainly in the middle
20s to the lower 30s...but it will feel colder given the winds.

Sunday and Monday...

Dry but unseasonably chilly weather will continue Sun into Mon
afternoon as high pressure builds in from the west.  High
temperatures on both days will be only in the 40s.  The colder/more
breezy day will be Sun and its possible that portions of the
interior high terrain does not break 40.

Monday night and Tuesday...

There continues to be excellent model agreement in an intensifying
low pressure system working northward from the mid Atlantic states.
The track/timing/strength of this low pressure system remains
uncertain given this is 4 days in the future. The lack of downstream
blocking or a strong Canadian high pressure system strongly favors a
rain event...but a bit of snow/ice can not be ruled out at the onset
across the interior.  While the system will be progressive...a
period of heavy rain is certainly possible with a general 1 to 2
inches of rain.  Therefore...we will need to watch for renewed
river/stream flooding given some MMEFS projections based on the very
wet weather we have had of late.

Wednesday through Friday...

Deep upper trough setting up across New England will result in dry
but unseasonably cold weather Wed into Thu.  Low temps mainly be in
the upper teens and 20s with highs mainly in the upper 30s to the
lower 40s.  It will also be quite windy Wed.  High pressure will
move off the coast Fri...resulting in some moderation in
temperatures. Appears mainly dry weather will likely persist.
