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 JSJ wrote its last area forecast discussion before this small craft advisory went out at Dec 19, 7:42 PM CST, 6 hours 27 minutes earlier.

Area forecast discussion, Dec 19, 7:42 PM CST, 6 hours 27 minutes before
Area Forecast Discussion
National Weather Service San Juan PR
942 PM AST Thu Dec 19 2019

.UPDATE...
No major changes were made to the inherited forecast. Showers
developed across northwestern Puerto Rico with Doppler radar
estimates around three inches over Moca. Once this activity moved
over waters, lightning was observed. For tomorrow, a small
fragment of moisture located east of the Lesser Antilles will
approach the local islands and it could bring a few passing
showers. However, rainfall activity should not be significant.

&&

.AVIATION...
Mainly VFR conditions are anticipated through the forecast period.
VCSH are expected for TJMZ/TJBQ between 2017Z-2022Z, which could
briefly reduced VIS to MVFR conditions. The TJSJ 20/00Z sounding
shows FL050 out of the ESE winds at 7 to 20 knots.

&&

.MARINE...
Seas below small craft advisory criteria are expected through the
end of the week. However, small craft operators are urged to
exercise caution due to seas up to 6 feet and winds up to 15
knots. For the beachgoers, there is a moderate risk of rip
currents for most of the local beaches.

&&

.PREV DISCUSSION... /issued 126 PM AST Thu Dec 19 2019/

SYNOPSIS...

We are still under an area of surface divergence and subsidence,
with satellite indicating very dry conditions across the region.
Only a few isolated and weak showers have occurred today, moving
from southeast to northwest, and minimal shower activity is
expected for the next few days. Winds and seas are calming down as
a large area of high pressure in the central Atlantic moves off
to the east. Long range models forecast a front approaching for
Christmas, though models disagree on the timing.

SHORT TERM...Rest of today through Saturday...

Overall fair weather conditions will prevail across much of the
forecast area and  most of the period as we should remain on the
subsident side of the subtropical ridge, forecast to remain in
place through the weekend. A weak short wave trough will move
across the west Atlantic by Saturday. This would briefly erode the
dominant ridge along with the trade wind cap inversion allowing
better chance for shower development. However, expect this to be
short-lived as another ridge of high pressure will quickly enter
and spread across the Atlantic once again during the remainder of
the weekend.

The overall forecast scenario should maintain light to moderate
easterly trade winds which will bring less frequent trade wind
moisture across the local waters and parts of the islands on Friday
into early Saturday. Locally and diurnally induced afternoon
convection will be limited to the interior and west sections of
Puerto Rico, and mainly on the west end or just downwind of the rest
of the islands.

By Saturday afternoon a weak frontal trough is to settle across the
west Atlantic and press against the Atlantic ridge located across
the central and eastern Atlantic. This in turn will favor a more
east southeast wind flow as the ridge will lift northeast of the
area. The east southeast wind flow should then pull additional
tropical moisture from the Caribbean across the region thus
supporting a better chance for early morning and afternoon
convection. The activity should however be of short duration with no
significant or widespread accumulations forecast for the period at
this time.

LONG TERM...Sunday through Friday...

FROM PREV DISCUSSION... /issued 509 AM AST Thu Dec 19 2019/

Ridging at the mid- to upper-levels of the atmosphere will hold
firm through at least Monday, resulting in relatively stable
weather conditions. However, the typical trade wind showers will
continue to move at times across the local waters and windward
sections each day.

Model guidance is suggesting a change in the weather pattern by
Christmas Eve with the arrival of an mid- to upper-level low and
a frontal boundary. The guidance had shown inconsistency
associated with the timing and location of these features.
However, if this unstable and wet pattern holds, showers and
thunderstorms would be observed during the Eve and the Day of
Christmas.

A ridge pattern and the typical easterly winds are forecast to
return across the Northeast Caribbean as the TUTT-Low moves into
the Central Atlantic Thursday and Friday.

MARINE...

Observations show subsiding winds and seas as high pressure moves
off towards the east in the central Atlantic. A Small Craft
Advisory still remains in effect for the offshore Atlantic waters
till 8pm, but advisories have expired everywhere else. Small
craft operators are however urged to exercise caution for the
remainder of the regional waters and passages due to seas up to 6
feet and the choppy conditions. Seas are forecast to increase once
again Saturday through Sunday.
