What forecasters said that day

The local office's own words before this gale 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 gale warning went out at Dec 18, 2:16 PM EST, 1 hour 9 minutes earlier.

Area forecast discussion, Dec 18, 2:16 PM EST, 1 hour 9 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
216 PM EST Mon Dec 18 2023

.SYNOPSIS...
Although conditions improve late this afternoon and early
tonight, it remains unsettled into Tuesday with clouds and
perhaps a spotty shower. A prolonged dry period sets up from
Wednesday through this weekend. Breezy conditions persist
through Friday. Temperatures will be near to below normal
through this weekend. Those hoping for a white Christmas will
need to wait for another chance in 2024, with little to no
precipitation expected after Tuesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
A powerful low pressure finally moves into northern New England
this evening, then farther north overnight. This will bring an
end to the rainfall from south to north late this afternoon.
While remaining gusty, wind speeds also will diminish. Thinking
we may be able to drop the current land-based wind headlines, at
some point before 7 PM this evening, especially across interior
southern New England. Will be making that decision within the
next hour or so.

Well above normal low temperatures expected tonight. Many
locations should have low temperatures around what would be a
normal high temperature for mid December.

&&

.SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/...
Deep mid level trough and its associated cold pocket of air
aloft establishes itself over our region Tuesday. Cold air aloft
will result in some diurnal cloudiness. Thinking mainly dry
conditions, but still cannot completely dismiss the idea of an
isolated shower, especially across the higher terrain. Slight
bump in in temperatures during the day, before falling off
during the afternoon and evening.

Turning even drier Tuesday night. West to northwest winds
diminish further. Near normal low temperatures.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...

Highlights

* Quiet and dry conditions

* Near to below normal temperatures

* Breezy through Friday esspically over the waters.

A strong 1035mb high begins to build north from the mid-Atlantic
states and merge with a 1045mb high dropping out of Ontario. This
will lead to a prolonged stretch of quiet and dry weather for
southern New England. As the surface highs move towards the region,
the pressure gradient will remain tight being sandwiched between the
remnants of Mondays low pressure system stalling offshore and even
intensifying a bit. What this will lead to is breezy conditions
lasting through Friday. Gusts inland wont be anywhere as strong as
we saw Monday topping out at 20-30mph on Thursday. Over the waters
and near the shores, Gale force gusts are possible with the latest
NBM showing 50-80% chance for gusts of 40mph mainly Thursday.
Starting Friday night, the center of the high pressure moves
overhead allowing the pressure gradient to relax and winds to calm
down. With little to no wind Friday night and beyond, overnight lows
likely begin to drop into the mid to low teens away from the coasts
with clear skies. Used a blend of the MOS guidance and NBM for
overnight lows Friday and beyond. As for highs, there will be a
downward trend through Friday and Saturday only topping out in the
mid to upper 30s. Next chance for precipitation could come Sunday
with the GFS showing a weak low exiting the Great Lakes, however,
the GFS appears to be an outlier at this time with ensembles showing
around a 10% chance for accumulating precip.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
Forecast Confidence Levels:

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Through this evening:  High confidence.

Mix IFR/MVFR conditions prevail as the last rounds of rainfall
move through late this afternoon/evening.

Winds will continue to gradually recede through the
afternoon/evening as well along with shifting more
southwesterly with time. Continued gusts 30-40 kt remain
possible.

Tonight: High confidence.

Lingering MVFR CIGS gradually give way to SCT/FEW CIGS during
the early overnight hours, allowing for VFR to prevail except
across the high terrain of interior MA/CT, which will take
longer to fully clear.

Winds continue to diminish out of the SW, with gusts generally
dropping to 20 kt or less.

Tuesday: High confidence.

Continued SCT-BKN VFR to MVFR bases, though may trend OVC in
the western higher terrain. Could see isolated -SHRA, or -SHSN
in the higher terrain of far W/NW MA, although drier weather
should prevail most of the time. W to WNW speeds 10-14 kt with
gusts 22-23 kt.

Tuesday Night: High Confidence.

VFR. Breezy.

KBOS TAF...High confidence in TAF.

Mix of MVFR/IFR will continue today through about 22Z as
continued SHRA and low CIGS prevail. After 22Z, gradual
improvement to fully VFR is expected.

Winds will also continue to diminish and gradually shift from S
to SW through the evening. Gusts 35-45 kt still possible at
times through about 22Z as well, but LLWS will quickly diminish
by 19/20Z, dropping below the 50 kt at 2kft.

KBDL TAF...High confidence in TAF.

Mixed MVFR/IFR in continued SHRA/BR and lower CIGS through about
22Z. After this, improvement to VFR is expected into the
evening/overnight hours, continuing into Tuesday.

Winds diminish, gusting 30-40 kt through 22Z today. Generally S,
shifting W winds overnight into Tue.

Outlook /Wednesday through Friday/...

Wednesday: VFR. Breezy.

Wednesday Night: VFR. Windy with gusts up to 35 kt.

Thursday: VFR. Strong winds with local gusts up to 40 kt.

Thursday Night: VFR. Windy with gusts up to 35 kt.

Friday: VFR. Windy with local gusts up to 30 kt.

&&

.MARINE...
Forecaster Confidence Levels:

Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.

Overall high confidence.

** Dangerous Marine Conditions Today **

Winds will continue to diminish this evening and overnight.
Storm Warnings will likely be converted to Gale Warnings later
this afternoon, and Small Craft Advisories overnight. Rough
seas will linger into Tuesday night, especially across the open
coastal waters.

Outlook /Wednesday through Friday/...

Tuesday Night: Winds less than 25 kt. Rough seas up to 12 ft.

Wednesday: Winds less than 25 kt. Rough seas up to 10 ft.

Wednesday Night: Low risk for gale force winds with gusts up to
35 kt. Rough seas up to 11 ft.
