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, 9:31 AM CST, 4 hours 16 minutes earlier.

Area forecast discussion, Dec 19, 9:31 AM CST, 4 hours 16 minutes before
Area Forecast Discussion
National Weather Service San Juan PR
1131 AM AST Sat Dec 19 2020

.UPDATE...
Showery weather prevailed across the north and east Puerto Rico
through the morning hours. The northern Virgin Islands had a
mixture of sunshine and passing showers. Under a northeasterly
wind flow showers will move into the interior and southwest
portion of Puerto Rico during the afternoon, and St Croix can
expect a mixture of sunshine and quick passing showers. Conditions
will improve after sunset when shower activity should diminish.
The best chance to observe no rain during the afternoon is the
northwest quadrant and the south central coastal portion of Puerto
Rico. St Croix, St John and Vieques will have a slight chance of
rain too.

&&

.AVIATION...

VFR conditions will persist with a passing showers at times mainly
at JSJ/IST/NPM/KPK. SHRA will develop across the interior and SW-
PR thru 19/23z. Winds will continue from the NE at 10-15 knots
with higher gusts in sea breeze variations. Winds will become calm
to light and variable aft 20/23z.

&&

.MARINE...
Expect marine conditions with seas at 5 feet or less and NE winds
between 10-15 knots through at least Sunday, when a northeasterly
swell is forecast to reach the local waters, deteriorating the
Atlantic and Caribbean Passages conditions.

&&

.PREV DISCUSSION... /issued 438 AM AST Sat Dec 19 2020/

SYNOPSIS...A mid-level high pressure will continue to dominate the local
weather pattern and it is expected to persist through the
weekend. Trade wind showers will affect the local area from time
to time. A northerly swell will result in hazardous marine
conditions from late Sunday into the workweek. In the mean time, a moderate
rip current risk continues for the north and eastern coast of Puerto
Rico and the U.S. Virgin islands.

SHORT TERM...

Trade wind showers across the regional waters moved from time to
time over portions of northern and eastern Puerto Rico, as well as
across the U.S. Virgin Islands. Up to a quarter of an inch was
observed with this activity over the north-central municipalities of
PR. Minimum temperatures ranged in general from the mid 60s across
the higher elevations to the high 70s across coastal areas.

A mid-level ridge extending over the local area from the western
Caribbean, will promote an east to northeast trade wind cap over the
region through the short term period. A cold front will remain far
north over the Atlantic waters and a surface high pressure is
expected to move quickly between Sunday and Monday over the western
Atlantic. This will bring a more easterly wind flow by the end of
the forecast period. While conditions are not favorable for
thunderstorm development, enough moisture content at lower levels
will be sufficient to induced diurnal shower activity over portions
of the interior and west/southwest PR each afternoon. Across the
USVI, the breezy trades will move quickly offshore any streamer type
of shower activity that develops around midday each day. Scattered
shower activity is expected during the overnight and early morning
hours across the USVI and the northern/eastern sections of PR each
day, as showers over the Atlantic and Caribbean waters are carried
by the ENE trades.

LONG TERM...

Model guidance continues to show weather predominantly dominated by
the mid level ridge spreading over our region from the western
Caribbean during the long term forecast period. This will promote
relatively stable conditions aloft. Additionally, a frontal
boundary over western Atlantic will move eastward and stall north
of our region by Thursday and quickly dissipate afterwards. This
could momentarily bring favorable conditions aloft with 500 mb
temperatures cooling to -8 degrees celsius. However, this will be
short in duration but possibly increase areal coverage of shower
activity with the presence of low level moisture for the latter
part of the period. At the surface, a high pressure over western
Atlantic will continue moving eastward over central Atlantic
maintaining a gentle to moderate east northeast trade wind flow
over the forecast area. Shallow areas of moisture embedded in this
northeasterly wind flow will reach the islands from time to time.
This will produce shower activity on a daily basis.

Precipitable water values will vary from 0.75 inches on Tuesday
morning sharply increasing up to 1.5 inches during the afternoon
hours, with varying values between 1.0 to 1.4 inches onwards until
the end of the workweek. Overall, isolated to scattered showers are
expected to stream across the local waters into coastal areas of
eastern and northern Puerto Rico and U.S. Virgin Islands during
overnight and morning hours, while scattered shower development
due to locally induced effects can be expected along the interior
and western sections of Puerto Rico in the afternoon hours of
each day. This weather pattern is expected to hold through the end
of the workweek.

AVIATION...Mainly VFR conditions are expected to prevail across all
terminals during the next 24 hours. However, trade wind shra may
cause brief MVFR cigs across TJSJ and the USVI terminals through the
morning hours. SHRA is expected to develop btw 16z-22z over
southwest PR, this may cause tempo MVFR cigs at TJPS. Low level
winds ENE at 10-15 kts.

MARINE...Seas at 5 feet or less are expected to prevail through
today. A northerly swell is expected to arrive late Sunday into
Monday, resulting in hazardous marine conditions, with seas
reaching Small Craft Advisory criteria. A moderate rip current
risk continues for the north and eastern coast of Puerto Rico,
Vieques, Culebra and all beaches in the U.S. Virgin Islands.
