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 Aug 21, 3:12 PM EDT, 1 hour 1 minute earlier.

Area forecast discussion, Aug 21, 3:12 PM EDT, 1 hour 1 minute before
Area Forecast Discussion
National Weather Service Boston/Norton MA
312 PM EDT Tue Aug 21 2018

.SYNOPSIS...
A low pressure system will bring two rounds of scattered showers
and embedded thunderstorms. The first late tonight into
Wednesday morning, then a second round Wednesday afternoon along
with the return of high humidity. High pressure will then
follow, bringing sunny conditions and comfortable humidity
Thursday and Friday. The high moves off the coast next weekend
allowing increasing chances of showers and thunderstorms.

&&

.NEAR TERM /THROUGH TONIGHT/...
Light drizzle/showers still lingered around the Cape and
islands. Not expecting that to change much late this afternoon.
Clouds will remain more prevalent across the eastern half of
southern New England. Farther west, mostly sunny skies are more
likely. Tweaked temperatures for the rest of this afternoon to
reflect observed trends.

Overnight, the main concerns will be the progress of a low
pressure and its warm front. Have high confidence in this low
pressure moving through the Great Lakes into Canada. have lower
confidence in the timing of a warm front. Many members of the
21/12Z guidance suite suggest this front could move into
northern New England before daybreak. Thinking is this likely a
bit too quick. Have more confidence in a warm frontal passage in
the 8-11 AM Wednesday time range.

This could be key to weather outcomes. The higher dew points
will be south of this warm front. These higher dew points will
provide the fuel for local downpours, as well as lowering cloud
bases. Some of the higher resolution short-term guidance suggest
high values of shear in the 0-1 km layer. Thus, still need to
be wary of rotating thunderstorms.

A caveat to this will be the time of day. Instability should not
be very high overnight, but would be a little higher if our
region can tap into the higher dew points south of the warm
front. At this point, have much more confidence in the potential
for locally heavy rainfall.

&&

.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
* A few strong to severe storms possible
* Localized street flooding possible, too

Wednesday...

Once our region firmly gets into the warm sector, looking at a
strong southerly low level jet to help recharge the instability
for Wednesday afternoon. Current timing for a cold front is
during the afternoon and evening. The quicker sunshine develops
in the morning, the greater the risk for strong to severe
thunderstorms during the afternoon and evening.

Otherwise, still expecting another day of higher heat and
humidity. This should start to an end later Wednesday night, as
drier air arrives behind a cold front.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
*/ Highlights...

 - Dry, comfortable weather Thursday into Friday
 - Return warmer, humid conditions beginning over the weekend
 - Accompanying chances of showers and thunderstorms

*/ Discussion...

Warmer than average temperatures forecast towards September. Latent
heat release per Soulik and Cimaron, becoming baroclinic, amplified
N Pacific standing wave pattern with H5 Bering Sea trof, NE Pacific
ridge, and subsequent W CONUS trof. The latter, an associated anti-
cyclonic Rossby wave break and attendant PV-streamer influencing
continued organized tropical convection out towards Hawaii. This and
upstream trends as seemingly the main Polar low retrogrades back N,
H5 ridging builds and is maintained over the SE CONUS extending into
New England into the end of the month per SW-NE pump. Ensemble means
signaling anomalous H85 warmth, CPC 6-10 and 8-14 day temperature
outlooks with high confidence noting warmer than average conditions.
Can't rule out dips within aforementioned SW-NE CONUS flow, trailing
cold fronts and chances of showers / thunderstorms, however becoming
diffuse up against the H5 ridge as associated mid-level energy lifts
N/E. It's back to N/W New England scattered wet-weather activity
that falls apart before ever reaching the S/E coast.

Low confidence forecast further out in time, not noting any targets
of opportunity. Overall, looking dry and comfortable Thursday into
Friday, followed by the return of warmer, more humid conditions for
the weekend into next week. Accompanying chances of showers and
thunderstorms give increasing instability. Too early to say with any
certainty as to strong / severe storm threats as well as any flash
flooding potential, however such risks are being considered given
antecedent conditions in addition to past storm trends /
outcomes.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Forecaster Confidence Levels...

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

Short Term /through Wednesday Night/...

Through 00Z...

Hold MVFR-IFR CIGs over a majority of southeastern terminals.
Perhaps interior SCT by then before dropping down again this
evening. E winds around 10 kts.

Tonight...

MVFR-IFR becoming widespread yet again. Onset -RA with isolated
TSRA towards morning. With any -RA, dropping VSBYs down to IFR
given forecast soupy conditions with increasing S flow. Marginal
LLWS possible by morning as a warm front approaches.

Wednesday...

Beginning early morning, widespread -SHRA with embedded
TSRA/SHRA. Anticipating mainly MVFR-IFR conditions with isolated
LIFR. A brief lull around noon to 2 pm, before another round of
TSRA/SHRA is possible with TEMPO IFR, if not already, before
clearing out.

Wednesday Night...

Mainly VFR.

KBOS Terminal...Hold MVFR for today, can't rule out brief,
TEMPO improvement to VFR. E winds prevailing up around 10 kts.

KBDL Terminal...High confidence in TAF.

Outlook /Thursday through Saturday/...

Thursday through Saturday: VFR.

&&

.MARINE...
Forecaster Confidence Levels...

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

Short Term /through Wednesday Night/...High confidence.

Low risk for a brief waterspout late tonight as a warm front
moves across the waters. Vsby lowered at times in morning fog
and scattered thunderstorms, then improving before second round
of thunderstorms in the afternoon.

Some risk for Small Craft Advisories along the southern outer
coastal waters due to marginal 25 kt gusts and 5 ft seas.

Outlook /Thursday through Saturday/...

Thursday: Winds less than 25 kt. Areas of seas approaching
5 ft.

Thursday Night: Winds less than 25 kt. Seas locally approaching
5 ft.

Friday through Saturday: Winds less than 25 kt.
