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 5, 12:12 PM EST, 2 hours 12 minutes earlier.

Area forecast discussion, Jan 5, 12:12 PM EST, 2 hours 12 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
1212 PM EST Fri Jan 5 2024

.SYNOPSIS...
High pressure builds into New England providing dry but cold weather
today and Saturday. A significant winter storm will impact the
region Saturday night into Sunday, with heavy wet snow likely
for much of the region. Dry weather Monday and likely lingers
into most of Tuesday. Then a return of active weather Tuesday
night into Wednesday, with the potential for a period of strong
winds, heavy rain, and some river and stream flooding.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
1215 PM Update:

Seeing some diurnal clouds spill over into western/central MA
and northern CT but these should dissipate this evening. Model
cross sections show potential for some low clouds to form
overnight, especially near coast, so bumped up cloud cover from
guidance a bit there. Otherwise we should see some increase in
high clouds but temperatures will still manage to fall into 20s
tonight due to dry airmass in place.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
3:45 AM update...

* Morning sunshine Sat gives way to increasing clouds

Saturday...

Very chilly start to the day and not much of a temp recovery given
morning sunshine fading to increasing clouds, as WAA pattern
overspreads the region. As winds become easterly, temps rebound to
near 40 across Cape Cod and Islands during the afternoon, with mid
to upper 30s elsewhere. Could see some light snow or flurries
develop late in the day from the WAA aloft and OES from off the
ocean. However, accumulating snow should hold off until
after sunset.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
3:45 AM update...

Highlights

* Still have details to hash out, but impactful Winter Storm late
  Sat through Sun.

* Dry with seasonable temps on Mon.

* Another impactful system pushes in later on Tue into Wed. Strong
  to damaging winds possible along with heavy precipitation.

Saturday Night through Sunday Night...

The main focus of the extended, but still uncertainty in the
forecast. There are two troughs that lift through our region during
this period. The first shortwave lifts from the Great Lakes/Mid
Atlantic late Sat and through southern New England by early Sun. A
deeper shortwave trough lifts from the Southern Plains/Lower
Mississippi River Valley late Sat into the TN/OH Valley by early
Sun. The trough lifts northeastward through New England by late Sun.
A Miller-A type coastal low will slide nearby/through the region.

Overall have not changed the forecast too much from the previous
shift. Guidance struggling on the degree of phasing and timeframe
this occurs between the 1st shortwave lifting out and the deeper
second shortwave moving in. Depending on the exact timing and
amplitude of things will influence the track and intensity of the
system impacting our region. The change in the latest update is
guidance has been trending a bit further to the southeast with a
later amplification of the surface low. Can clearly see this with
total QPF probs of AOA 1 inch shifting further to the SE. Due to
this opted to expand our Winter Storm Watch a tier of counties
further southeast.

The GEPS along with the GEM are the most amplified solution and our
phasing occurring right over us, which neg tilts the trough/cuts off
closer to our south coast. This results in  higher snow totals
across the interior. At the moment the GEPS/GEM appear to be the
outlier with essentially all of their members hitting at this
solution. The majority of GEFS/EPS members along with GFS/ECMWF have
trended to a less amplified wave with phasing occurring a bit late in
the game. This still results in an impactful snowfall, but the
highest totals shift further to the SE versus a mostly interior
event. Still would see snowfall across the interior, but less
realized than what the GEPS/GEM advertising. Stay tuned as many of
these details hinge on mesoscale factors, such as banding, which are
better forecast when we get into more convective allowing models
window.

Still have concerns along and southeast of the I-95 corridor with
the temps and exact ptypes. This is still clearly see this per
GEFS/EPS probs of 2m temps AOA 32 degrees with a tight probability
gradient. This will roughly be where the rain/snow line will be,
which will impact ptypes and where exactly heavy wet snow is
located. The heavy wet snow coupled with strong winds could result
in potential power outages. Further to the NW ptype will not be as
much of a concern with temps remaining cold enough for all snow. The
big question is how much QPF is realized as we've got two surges of
precip. Can clearly see this idea via the NAM in Bufkit soundings
with an initial lift within the DGZ late Sat/early Sun AM. This is
followed by dry air intrusion Sun AM and followed by another uptick
in moisture later on Sun as the system is deepening and decent lift
within the DBZ - depending on where you're located.

The moisture remains high for this time of year with PWATs of 0.5 to
0.75 inches, which is around the 75th-90th percentile per SPC
sounding climo for CHH. Will also have strong winds, especially
along the coastal plain where Wind Advisories may be needed.
Guidance indicating a 30-50 kt E to NE jet sliding through late Sat
into Sun. Winds turn more NNE/N later on Sun as the system pivots
offshore. Have bumped up our wind speeds/gusts a bit from the
previous forecast. At this point gusts of 25-35 mph across the
interior are possible and for the coastal plain 35-50 mph. Best shot
for the 50 mph gusts is across the Cape/Islands.

Monday through early Tuesday...

High pressure builds into and through our region during this
timeframe. The high shifts into Nova Scotia by late Tue. The result
will be dry and quiet weather. Temps will be around seasonable
levels on Mon and above normal on Tue. Temps warming up on Tue with
SSE/S warm air advection. This brings in 0 to 4 degree C 925 hPa
air. Highs topping in the 40s on Tue.

Late Tuesday through Thursday...

The active weather pattern continues. Signals still pointing to
another impactful weather event for southern New England. Given the
focus on Sat/Sun have just stuck with the NBM for now. Ensembles
still pin point another amped up system. The EPS/NAEFS are 4-5 STD
above model climo for winds and PWATs 2-4 STD above model climo as
well. At this point anticipating strong to perhaps damaging winds
along with heavy precipitation and well above normal temps. Stay
tuned as details will become clearer as we get closer to the event.

Turning drier late in the week.
