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 Apr 20, 1:58 AM EDT, 37 minutes earlier.

Area forecast discussion, Apr 20, 1:58 AM EDT, 37 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
158 AM EDT Sat Apr 20 2019

.SYNOPSIS...
A slow moving low pressure systems approaching from the west
will bring numerous showers with locally heavy rainfall later
tonight into Saturday night. The low pressure moves slowly
across New England into early next week. Off and on rain chances
through Wednesday, perhaps a drying trend for late week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
155 AM update...

Numerous showers, locally heavy lifting north across western
MA/CT with axis of heavy rain extending south along the mid Atlc
coast. The heavy showers are aligned with the low level jet
which remains in same location overnight. Expect widespread
rainfall, heavy at times to persist in western New Eng
overnight while axis of rain slowly shifts eastward. An isold
t-storm is possible. A few showers expected in eastern New Eng
but there will be dry periods as well. Mainly dry overnight
across far SE New Eng.

Previous discussion...

Scattered showers with brief downpours lifting north across SNE
this evening, but organized axis of heavy rainfall remains well
to the north and west along the boundary. Showers will increase
in coverage overnight across western MA and the CT valley as
convection along the mid Atlc coast lifts northward along the
axis of the increasing 850 mb jet. Given anomalous PWATs,
locally heavy rainfall is likely and can't rule out a rumble of
thunder. Across eastern New Eng, just a few showers are possible
but much of the night will likely remain dry, especially SE New
Eng which remains on the periphery of the subtropical ridge.

Areas of fog developing along the south coast which should
become more widespread overnight near the coast. It will be a
warm and humid night for mid April with low temps 60-65, except
50s along the south coast.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Saturday...

Showers continue thru Saturday, as the very high precipitable water
plume 3-4 SD from normal continues to feed into our area thanks to a
deep and strong southerly flow. High amplitude trough containing
vertically stacked/closed low to our southwest, positioned over the
central Appalachians/lower Ohio Valley thru the day.

The axis of heavy rainfall will gradually shift from W to E
across our area over the course of the day. Including the
rainfall from Friday night, rainfall amounts of 1-2 inches with
locally higher amounts are expected in western to central MA
and northern CT, where a Flood Watch continues from late tonight
thru Saturday evening. To the east of the Flood Watch area,
somewhat less rain is expected, with 0.75 to 1.5 inches from Fri
night thru Sat.

Highs Sat 65-70, but a bit cooler immediate south coast.
Dewpoints will remain around 60 so continued humid feel for mid
April. South winds gusting 25 to 30 mph expected during the day.

Areas of fog, locally dense may linger into Saturday especially
along the south coast.

Saturday night...

The bands of rain shift towards the eastern half of the CWA as
the night wears on. Rainfall totals diminish, expecting a half
inch to inch over the Cape and Islands, and less to the west.
Rainfall should be more light over western MA/CT.

With the exiting jet, wind gusts will decrease quickly, leaving
light winds by daybreak Sunday. Temps fall into the low to mid
50s.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
*/ Highlights ...

 - Sunday soaker E but seemingly pleasant W
 - Monday showers, potentially instability driven and heavy
 - Tuesday could be fairly warm, close to 80 for some
 - Remainder of the week appears seasonable and dry

*/ Overview ...

Rainy, cool pattern. Brief NW Atlantic rex-block will put the brakes
on the upstream pattern. Slowing our present storm system up against
a progressive N Pacific flow, onshore mild flow invokes increasing
heights across the CONUS, subsequently the present storm system cuts
off from the maritime flow, lingering into early next week. Moist
sub-tropical moisture neighboring, wrapping into the cut off closed
low, some initial breaks Sunday, especially W with a steady rain E,
evolves into a swirl of showers and winds, broken cloud decks, cool
conditions for Monday. Tuesday could turn out nice before additional
Pacific energy and continental-tropical airmass stretches out over
the NE CONUS along a weak cold front. Parallel wind fields to the
front, less frontogenetical lift / ascent, outcomes could be fairly
light, mainly confined to the high terrain. The remainder of the
week, seemingly on the W-cusp of a broader H5 trof over SE Canada
with indications of the maritime pattern being nudged N with the
Spring-time pattern, perhaps falling into a more seasonable and
dry pattern with prevailing W/NW flow.

*/ Details ...

Sunday ...

Soaker E as the W remains dry. Occluding front meandering E slowly
with accompanying sub-tropical precipitable water axis. Dry slot
wrapping it, the continued frontogenetical forcing E poses soaking
rains early for far E New England, especially SE MA, whereas cloud
decks becoming broken, perhaps scattered allowing abundant sunshine
and temperatures to warm up to around 70, more so if winds remain
light. Into evening and overnight, a renewed low pressure emerges
along the front, backing and stacking beneath the cut-off low which
is the main weather story for Monday.

Monday ...

Expect swirling light showers and winds beneath the cut off low from
the steering flow. Accompanying cooler mid-level temperatures aloft,
prefer the lower end of forecast guidance with 2m temperatures given
anticipated broken cloud decks. However this will invoke steep lapse
rates throughout the column. Potential breaks of sunshine, warming
up accordingly, could get instability-driven activity. 19.12z NAM
hints at the potential for soaking rains around peak heating midday
Monday. Thunder certainly possible. Keep with chance PoPs with a
slight chance of thunder mention.

Tuesday onward ...

Optimistic we'll over-achieve on Tuesday to the point that we could
see some locations close to 80 degrees. This prior to a sweeping
weak cold front, some light showers mainly along the high terrain as
moisture is somewhat limited as is the forcing and ascent. Slight
chance PoPs. The remainder of the week seemingly is dry, seasonable
with cooler air holding firm aloft ushered by W/NW winds beneath the
W-periphery of a broader H5 trof over SE Canada.
