PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Small Craft Advisory for hazardous seas means that waves are
expected to be hazardous to small craft. Mariners should avoid
shoaling areas. Long period swell can sharpen into large breaking
waves in shoaling areas. It is not unusual for waves to break
much farther from shoaling areas than is normally experienced.
Remember, breaking waves can easily capsize even larger vessels.

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 Mar 24, 1:43 AM EDT, 1 hour 55 minutes earlier.

Area forecast discussion, Mar 24, 1:43 AM EDT, 1 hour 55 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
143 AM EDT Sat Mar 24 2018

.SYNOPSIS...
A series of upper level disturbances impact the region over the
weekend with occasional rain and snow showers, but these will
be hit and miss. Conditions improve with high pressure on
Monday, then a warming trend is expected through the middle of
the week. The chance for rain then increases towards the end of
the next workweek.

&&

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

140 am update...

A scattered to broken deck of mid level cloudiness will persist
through daybreak. Dry weather should prevail though with dry low
levels and little synoptic scale forcing for any precipitation.
Low temperatures will generally be in the upper 20s to lower
30s.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Upper trough remains over New England Saturday and Saturday
night. The shortwave moving through that trough moves off to the
east Saturday. But another shortwave from Hudsons Bay drops
south tonight and moves across New England Saturday and Saturday
night. A pocket of colder air aloft moves through with this
second trough, and moisture cross sections continue to show high
values to at least 700 mb. Lapse rates 925 to 700 mb are forecast
to reach 7C/KM. Lift will also be stronger, roughly 20 mb/hr
rather than the 10 mb/hr forecast for tonight. Best forcing
looks to be along/east of the Worcester Hills, covering Eastern
Mass and RI.

Considering all of this, we will bring chance pops to these
eastern areas and slight chance pops to Western Mass and
Northern CT. Temperature profiles favor light rain during the
day Saturday and snow for Saturday night. Snow accumulation
potential looks around an inch, possibly two inches in spots.
Best chance for accums would be over Northeast Mass, where the
forcing is strongest.

Mixing reaches to 850 mb with winds in that layer at about 15
knots and temperatures at the top of the layer -8C to -9C. Thus
expect north winds to gust 15-20 mph and max sfc temps in the
upper 30s to mid 40s.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Details...

Sunday...

Upper low centered over and to the east of southern New England
moves southeastward, while strong 1040 mb high centered over
Quebec shifts to the St. Lawrence River Valley to northern New
England. The high pressure keeps a low level NE onshore flow in
place over our area, which will keep temps well below seasonal
normals. Thinking highs will be in the mid 30s to around 40.

A tightening pressure gradient is expected as low pressure moves off
the Carolina coastline and tracks eastward. So expect some increase
in NE winds, with gusts up to 25-35 mph along E coastal areas as
well as on the islands. Models indicate a short wave rotating into
our area during the day. This should yield more clouds than sun and
isolated to scattered snow/rain showers. Looking at Bufkit model
soundings, the better chance for showery weather is over central and
eastern MA/northeast CT/RI, where onshore flow keeps low levels
moist. However further west into the CT Valley region of MA/CT, the
chance for measurable precipitation is diminished and hence it
should be drier there.

Sunday night through Monday night...

Cool Canadian high pressure sinks southward into New England,
yielding dry conditions with a continuation of somewhat below normal
temperatures thanks in part to a continued onshore breeze.
Quite dry air in place thanks in part to subsidence inversion,
so mostly clear/mostly sunny skies forecast for this timeframe.
The exception to this will probably be over the Cape and
Islands, where just enough low level moisture may linger to
keep skies partly to mostly cloudy at least into Sunday night.
Lows in the 20s to around 30, and highs Monday in the mid 30s to
mid 40s.

Tuesday...

Models show mid level ridging and surface high pressure over our
area, yielding dry conditions with a warmup. This dry/warm region
narrows during Tuesday night, with a low pressure system passing
thru the Great Lakes Region, and an offshore low pressure
retrograding somewhat to the west. Thus we may see an increase in
clouds Tuesday night.

Wednesday through Friday...

Model spread brings uncertainties on timing of different features,
but overall expecting an increase in moisture with the potential for
rain and snow showers. For Wednesday low pressure lifting well
northeast of the Great Lakes Region, associated cold front may bring
showers to southern New England. However mid level ridging
could persist and keep the day dry. At this time limiting pops
slight chance.

During Thursday-Friday, mid level ridging is replaced with a broad
trough placing the east coastal US in SW flow. Should see an
increase in southern stream moisture heading out way as a low
pressure system moving towards and into our area, bringing a chance
for rain.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
Forecaster Confidence Levels...

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

Short Term /through Sunday/...

Today...High confidence. Mainly VFR despite a scattered to
broken deck of mid level cloudiness. A few spot rain/snow
showers may develop...mainly late in the day with the best
chance across eastern MA.

Tonight and Sunday...Moderate to high confidence. Conditions
should gradually deteriorate to MVFR threshold late tonight into
Sunday morning in lower clouds and scattered snow showers. The
snow showers will be most numerous across eastern MA. Some
improvement expected Sunday afternoon across the interior...but
MVFR conditions likely persist across eastern MA along with a
few snow showers. NE wind gusts of 20 to 30 knots develop
Sunday with the strongest of those across southeast New England.

KBOS Terminal. High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Sunday Night through Wednesday/...Moderate Confidence.

Sunday Night: VFR. Windy with areas gusts to 30 kt.

Monday: VFR. Windy with local gusts to 30 kt.

Monday Night through Tuesday Night: VFR. Breezy.

Wednesday: Breezy. Slight chance SHRA.

&&

.MARINE...
Short Term /through Sunday/...High confidence.

Tonight...High confidence.

Quiet tonight with winds below 25 knots and seas below 5 feet.

Saturday...High confidence.

Quiet weather continues. Scattered rain showers in the
afternoon/evening may lower vsbys along the Eastern Mass
coastline.

Saturday night...Moderate confidence.

A wind shift moves south across the waters after midnight. Snow
showers along this line may bring brief reductions in vsbys.
The wind shift will turn winds from the northeast and bring
building speeds. Gusts late at night will be between 25 and 30
knots. Seas will build after midnight, reaching heights of 5-7
feet on the eastern waters.

Outlook /Sunday Night through Wednesday/...Moderate Confidence.
