What forecasters said that day

The local office's own words before this small craft advisory 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 small craft advisory went out at Feb 25, 3:27 AM EST, 0 minutes earlier.

Area forecast discussion, Feb 25, 3:27 AM EST, 0 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
327 AM EST Tue Feb 25 2020

.SYNOPSIS...
A weak cold front will drop south across the region today with a
wind shift to northeast but it will be another mild day. Other than
a period of light rain this morning over Nantucket, mainly dry
conditions are expected today. The front will settle south of New
England tonight and Wednesday with a moist northeast flow bringing
patchy light rain and drizzle at times. A stronger frontal system
Wednesday night into Thursday should produce a period of steady rain
for most, with a potential for light accumulating wintry mix in the
higher terrain of northwest Massachusetts. Turning colder and
blustery late in the week into the weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Mid level shortwave passage this morning combined with deep moisture
lifting north from the ocean will bring a period of rain to mainly
Nantucket this morning. Hi-res and global guidance are indicating a
few hours of rain here which may also briefly impact portions of the
Cape. The rain which impacts Nantucket is developing off NJ coast
and lifting NE. Otherwise, weak subsidence behind the shortwave and
subtle drying in the column should result in a mainly dry day
although can't rule of some light rain/drizzle late in the day south
of the Mass Pike as moisture returns from the south and west. 925 mb
temps remain mild today and with a bit of sunshine possible, highs
should reach into the mid 50s away from the coast with some upper
50s possible, except cooler northern MA as weak cold front drops
south across SNE with a wind shift to NE. This wind shift will
result in temps falling through the 40s along east coastal MA
during the afternoon.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
Tonight...

Weak front sets up south of New Eng with a sfc wave tracking along
the boundary to the south. Weak warm advection and deep moisture
through the mid levels should bring some light rain/drizzle to the
region, which may mix with some snow late tonight and Wed morning
over the higher elevations in far northern MA where the column is
marginally cold enough. Little or no accum is expected. Lows will
range through the 30s with light NE winds.

Wednesday...

Mid level trough amplifies from the Gt Lakes to the Ohio valley with
downstream ridge building over New Eng. Mid level drying from the
south moves up across SNE during the day. Low levels will be rather
moist so low clouds expected with some patchy light rain/drizzle at
times but most of the day should be mainly dry. Leading edge of
steadier rain will be approaching from the west but should hold off
until Wed night. Low clouds and NE wind will result in cooler temps
with highs upper 30s to mid 40s.

&&

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

* Strong frontal system may bring a period of light accumulating
  wintry wx to the higher terrain in the Berkshires Wed night into
  early Thurs. Mainly steady rains elsewhere with strengthening E
  winds.

* Cold frontal passage Thurs with falling temperatures and blustery
  W winds.

* Below-avg temps and cold wind chills late in the week into the
  weekend. Coldest conditions Sat and Sun.

Details...

Wednesday night and Thursday...

A quick hitting but potent rain system will bring gusty winds,
widespread rain, and potential for high elevation snow/wintry mix
late Wednesday night into early Thursday. A mid level trough over
the Great Lakes becomes negatively tilted Wednesday night as its
attendant sfc low moves up into eastern Canada and a secondary low
forms along the frontal boundary. Out ahead of the digging trough a
plume of subtropical moisture (PWATS >1") is pulled north over the
region. This is coincident with warm frontal isentropic lift,
diffluent flow at 500mb, a 50-60 kt LLJ, and placement beneath the
left exit region of a strong upper jet. The combination of moisture
and lift will bring widespread locally heavy rain to much of the
region starting Wednesday night and ending sometime Thursday morning
or early afternoon. Winds may be gusty as some of the strong LLJ has
potential to be mixed down in heavy precip. How quickly the rain
ends on Thursday will depend on timing the cold frontal passage and
arrival of the mid level dry slot (sometime Thursday morning).

Thinking continues to be that most locations will remain warm enough
for QPF to fall as rain (to the tune of 0.5 to 1"). However, the
typically prone eastern slopes of the Berkshires will be the
exception, likely changing to a wintry mix of snow, freezing rain,
and/or sleet for a time. At this point, 60-72 hours out, there
remains considerable uncertainty on the extent of the wintry precip
based on how cold temperatures get in the low levels. The NAM
continues to be the cold outlier, showing several inches of snow
across northern MA while the GFS/EC has little to none outside of
the northern Berkshires. Over the next 24 hours as we get into range
of the hi-res guidance like the HREF and NAM-3k we'll have a better
idea on chances for slick roads during the Thursday morning commute.
Temperatures will have been so mild for many days, though, that
impacts may be lessened when it comes to slick roads.

By Thursday afternoon the cold front swings through bringing in a
colder and drier airmass. This pulls in colder air aloft, steepening
lapse rates and mixing down some gusty winds. We're looking at wind
gusts 20-30 mph, higher along the south coast. High temps will
depend on how quickly the cold front arrives, but for now looking
like we'll reach the upper 40s before temps plunge behind the front
mid-late afternoon.

Friday through Monday...

This ushers in a pattern change bringing temps back down into the
30s for highs and teens/20s for lows. The cold pool aloft moves
overhead Sat/Sun so these will be the coldest of the forecast. The
upper trough lingers over the eastern seaboard through the weekend
with moisture moving in and out of the column so expecting partly
cloudy to mostly sunny skies, but no precipitation to speak of. By
Monday temps should be on the rebound with continued dry weather
under building high pressure.
