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 Apr 10, 4:14 AM EDT, 1 minute earlier.

Area forecast discussion, Apr 10, 4:14 AM EDT, 1 minute before
Area Forecast Discussion
National Weather Service Boston/Norton MA
414 AM EDT Fri Apr 10 2020

.SYNOPSIS...

Powerful low pressure over Nova Scotia will maintain cool and
blustery weather across southern New England today along with
scattered rain showers. Dry weather Saturday but remaining cool and
brisk. High pressure south of New England provides milder
temperatures for Sunday with highs 55-60. Powerful low pressure then
tracks thru the Great Lakes Monday with heavy showers and strong
winds to impact southern New England. Dry and seasonable weather
returns Tuesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

4 am update ...

Today ...

Mainly dry conditions this morning with just some lake effect
rain/snow showers from NY state spilling over the Berkshires and
Litchfield Hills into the CT river valley. Impressive cold pool of
-36C at 500 mb streaming S-SW of New England and yielding scattered
rain showers currently across northern NJ/NYC into western LI. This
activity will track south of New England this morning. As this cold
pool moves offshore, wrap around moisture and warmer air aloft
(TROWAL) pivoting cyclonically around mid level low into southern
New England this afternoon. Thus expect morning sunshine to give way
to afternoon clouds and scattered rain showers with scattered snow
showers over the high terrain. Not a wash out but definitely have to
dodge a few chilly showers/sprinkles this afternoon and early
evening.

Cool temps aloft (-5C at 850 mb) combined with mostly cloudy
conditions this afternoon will limit highs to 45-50, low 40s in the
high terrain. Normal high for April 10th is 52-58, so a few degs
cooler than normal but it will feel even cooler given brisk west
winds today sustained 15 mph but gusting 25-35 mph at times.
Strongest winds will be across the Islands given stronger wind
fields aloft and deeper boundary layer with gusts up to 50 mph at
times. Therefore have posted a Wind Advisory for Block Island,
Marthas Vineyard and Nantucket.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...

Tonight ...

Any leftover sprinkles/light rain showers (light snow showers high
terrain) during the early evening will move offshore and give way to
dry weather. CAA continues with 850 mb temps lowering to about -7C.
Lows will be in the 30s but a NW breeze will yield wind chills in
the 20s.  Strongest NW winds over Cape Cod and Islands with gusts up
to 30 mph.

Saturday ...

Another northern stream trough moves across the area in the morning
but its cold pool remains north of region over northern VT/NH into
ME. Thus column not as cold and drier than today. As a result more
sunshine Saturday than today yielding temperatures a few degs warmer
with highs in the low 50s. Not quite as windy as well with WNW winds
10-15 mph with gusts up to 25 mph. So overall some improvement and
more pleasant than today.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...

Highlights...

* Temperatures running near to below normal Saturday, then a warm up
  Sunday-Tuesday

* Rain, thunderstorms, and gusty winds on Monday

* Drier and cooler through mid week

Details...

Saturday night and Sunday...

The ridge axis moves overhead Saturday night bringing light winds,
clear skies, and efficient radiational cooling. MOS guidance has
been given more weight with the low temperatures for this reason;
we're looking at most interior locations dipping to near or
below freezing.

By Sunday on the back side of the ridge warm SW flow advects in
milder air and mid/upper level moisture. So, while clouds will be on
the increase through the day, temperatures will be quite a bit
warmer than Saturday, in the upper 50s...closer to the low 60s for
the CT Valley. The exception, as per usual, will be the Cape and
islands where southerly flow off the ocean keeps temps in the low
50s. Also on Sunday a modest 25-35 kt LLJ moves overhead. Given WAA
at the sfc, the BL should be well mixed to near 800 mb leading to
wind gusts of 25 to 35 mph at the surface. Overall, a mild, partly
cloudy, and breezy end to the weekend.

Sunday night and Monday...

Late Sunday night and Monday our next strong storm system will
impact southern New England bringing widespread heavy rain, strong
winds, and thunderstorms. At the synoptic scale we see the merging
to two distinct disturbances; one, a cutoff low spinning over the
desert southwest all weekend which is finally pulled into the
steering flow Sunday and eventually phases with a digging trough
over the northern Plains, lifting through the Great Lakes on Monday.
This will be a very strong and expansive system. Global guidance
progs the sfc MSLP around 992 mb at 00Z Monday and by 00Z Tuesday
its around or sub 970 mb. Jet dynamics are very strong as a
result...850mb jet of 80-90 kts! GEFS ensemble guidance shows v
(southerly) component of the jet at 5-6 standard deviations above
normal. The EC isn't quite as bullish, but still very strong.
Regardless of the exact values, this together with a large moisture
plume (PWATs near 1.5" and dewpoints in the upper 50s) and cold
frontal forcing will bring widespread heavy rain to the region
starting Monday morning and exiting by the early hours of Tuesday.
While model soundings show enough of a slight inversion to keep the
very strong winds aloft as a whole, heavy downpours could bring
strong to damaging winds from aloft down to the surface. Convection
likely makes a return as well, with modest elevated instability (200-
500 J/kg CAPE) and strong shear (50-60 kts 0-6 km bulk shear).
Thunderstorm chances increase late Monday morning in western MA/CT
and move east through the day. The cold front then moves through
Monday night into Tuesday morning ushering in a drier and cooler
airmass. Rainfall totals look to be from 0.5-1.0" with locally
higher amounts possible under heavy downpours.

Tuesday through Thursday...

The low pressure exits into Quebec by daybreak on Tuesday leaving us
under a broad east coast trough through mid week. At the surface
high pressure edges its way east into the areas helping keep precip
away, and suppressing a storm system to our south over the Atlantic
on Wednesday. Overall a dry period is expected with the return of
cooler temperatures, down into the low 50s by Wednesday. Tuesday
will be dry but windy as CAA aids in mixing down some gusty west
winds, generally 20-30 mph. By Thursday another trough brings our
next shot of rain to the region.

&&

Today thru Saturday...
