What forecasters said that day

The local office's own words before this winter storm 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 winter storm warning went out at Jan 6, 12:26 AM EST, 2 hours 58 minutes earlier.

Area forecast discussion, Jan 6, 12:26 AM EST, 2 hours 58 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
1226 AM EST Thu Jan 6 2022

.SYNOPSIS...
Periods of rain are expected this afternoon before a cold front
crosses the area tonight. Dry and colder weather returns
Thursday. Snow is expected late Thursday night into Friday as
low pressure passes southeast of New England. After a dry and
cold day Saturday, some light rain, with a light wintry mix
inland, is expected Sunday. A shot of arctic air should follow
early next week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
1230 AM Update

Forecast remains on track. Last of showers are exiting Nantucket
this hour. Patchy dense fog has developed in the valley areas,
particularly the CT River valley where visibilities have come
down to 1/4SM. SPS is in effect for patchy dense fog for the
next few hours. Furthermore, sub-freezing temperatures and wet
roads could lead to some patchy black ice tonight as well. Thus
the SPS has been updated to include this hazard as well.

700 PM Update:

Made some tweaks to PoPs/Wx to match current conditions and
expected near-term trends.

Frontal rains continue to shift offshore, now primarily
affecting Cape Cod and the Islands. Some brief downpours
possible in some of these steadier rains thru 10 PM before
moving further seaward.

In the post-frontal air mass, clearing and drying appears to be
delayed with continued SW flow. Noting observations in the CT
Valley in the Springfield and Hartford metros that pooled,
trapped shallow moisture and lack of mixing is leading to areas
of patchy fog, in some instances of the locally dense type. RAP
soundings indicate fog may not lift until late tonight
(as late as midnight?). May opt to issue an SPS if conditions
do not improve.

While skies should clear out, dewpoints will be slower to fall
limiting evaporation potential. Any standing water on roads
could re-freeze into black ice as temperatures especially in
interior MA/CT fall below freezing. See the SPS sent earlier.

Lows still look on track with mid/upper 20s to near 30 in the
interior NW of I-95, and the mid to upper 30s eastern MA and
eastern/coastal RI.

Previous discussion:

Mesonet observations show temperatures have risen above freezing
across interior so the Winter Weather Advisory was allowed to
expire. Expect periods of rain through afternoon per latest
radar trends. Temperatures have surged into lower 50s across
parts of E MA and RI due to increasing southerly flow while
farther inland low level cold air remains entrenched with
temperatures in mid and upper 30s. Patchy fog will linger in
interior through this evening where mixing will be more limited.

Later tonight, cold front crosses SNE bringing wind shift to W
along with drier air into region. Expect at least partial
clearing overnight as temperatures fall back into the upper 20s
to mid 30s. Could be some spotty icing across interior due to
leftover standing water, especially since winds will be light,
so we are considering a Special Weather Statement to highlight
this concern.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...
Updated 1245 PM Wed

High pressure builds over SNE Thu. Should be enough mixing for
some 20-25 mph gusts, mainly near coast, otherwise expect plenty
of sunshine until clouds begin to increase during afternoon
ahead of our next system. Highs will top out in 30s and lower
40s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Highlights...

* Coastal low-pressure system to bring accumulating snow to
  Southern New England very late Thurs into Fri. Heavy snow
  possible particularly I-95 Boston to Providence corridor into
  Southeast MA. Significant impact to the AM commute.

* Milder Sun with a period of light wintry mix interior and
  generally light rain showers along the coastal plain.

* Arctic outbreak possible later Mon into Tue.

Details:

Thursday Night into Friday:

* Winter Storm Watch issued for the Boston-Providence I-95 corridor
  to the South Coast of RI/MA. Increasing concern for heavy snow to
  impact Friday morning's commute, with very difficult travel more
  likely in the Watch area.

We continue to monitor details regarding a potential winter storm
that is likely to bring accumulating snow for much of Southern New
England later Thursday night into Friday.

There remains uncertainty on the storm's eventual track. Most of the
deterministic and ensembles/their members are close to the 40N/70W
benchmark. But there still remain a good deal of spread with some
tracking over the benchmark and others more southeast. Heights at
700 and 850 mb are also open-wave, reflecting a more progressive,
quick-hit system.

Snow should begin to break out around or just after midnight in
western MA/CT, then into the pre-dawn Friday hrs for the rest of
Southern New England. Period of greatest snow accumulation is
centered around the early to late-morning hrs with likelihood of
difficult travel during the AM commute. We then should see clearing
take place from west to east through early to mid afternoon. Lighter
if any additional new snow for the PM commute.

Storm total QPF amounts, heavily utilizing WPC's QPF, range from a
quarter-inch to a third of an inch for northern and western MA into
CT, between a third to a half-inch into Middlesex and Worcester
Counties, and half to two-thirds of an inch across the I-95 Boston-
Providence corridor SE to Cape Cod and the Islands (where rain will
mix in).

This has the look of an Advisory-level event for most of Southern
New England with updated snow amounts ranging from 2-4 inches from
the Berkshires to the CT Valley, a general 3-5 inches with potential
for 6 inches across eastern CT, Worcester County northeast into
northern Middlesex and the North Shore; have 4-6 inches with
potential for local higher amts across the I-95 corridor in RI/MA
into southeastern MA. While it is not well agreed upon, and it is
possible that banding could extend further back N/W than current
indications if a closer-to-the-benchmark track ensues, but there is
some consensus on bands of locally heavy snow during the Friday AM
commute along the I-95 corridor. Even the more offshore NAM solution
shows about 20 microbars of lift in the snow-growth region between
09-15z, with the GFS/ECMWF showing similar but augmenting that with
fairly robust 850-700 mb frontogenesis across eastern MA/RI.

Certainly seen the influence and impact heavy snow on roads can
cause over the last few days, and thus have opted to issue a more
impact-based Winter Storm Watch from 1 AM to 1 PM Friday across the
Boston-Providence I-95 corridor into southeast MA. It is in this
area that we feel reasonably confident on heavy snow impacting the
AM commute where snow rates could be as much as 1 inch per hr and
possible local whiteout conditions. However given the continued
uncertainty in storm track, it is possible this area of heavy snow
and potential banding could shift NW or SE of the I-95 area.

Friday Night into Early Next Week:

Focus was mostly on the winter storm, and didn't make significant
alterations over NBM in much of this period. Couple systems to
contend with, with temperatures generally below average.

Large high pres settles in to Southern New England on Friday night
into Saturday. Should have a period of drier weather with decreasing
NW winds Friday night. Exactly how cold we get will hinge on winds
diminishing to light. Temps below-normal.

Warm up towards later Saturday into Saturday night, though a frontal
system looks to bring another snow to rain mix to the interior on
Sunday. Temps Sunday trend above normal around the lower 40s.

Temperatures then take the Arctic plunge behind this frontal
system as a surge of Arctic air looks to move across New
England. Core of the cold is centered on Tuesday where highs may
only reach the teens to lower 20s with NW breezes to boot.
