Area Forecast Discussion
National Weather Service San Juan PR
413 AM AST Thu Nov 8 2018

.SYNOPSIS...A more stable weather pattern will gradually build
across the region through the weekend as the mid to upper-level
trough lifts northward and weakens and a mid level ridge replaces
it. Enough low-level moisture, however, will remain in place to
result in trade wind showers across windward areas during the
overnight and morning hours followed by afternoon convection
across interior and western PR. A wetter weather pattern is
possible by the middle to latter half of next week as a trough
pattern sets up over the region to result in an increase in shower
and thunderstorm activity.

&&

.SHORT TERM...Today through Saturday...

An induced surface trough and plenty of tropical moisture brought
showers and isolated thunderstorms across the northern U.S. Virgin
Islands and the east and north sections of Puerto Rico overnight.
Some of these showers produced periods of moderate to heavy showers
across these areas. Due to unstable weather conditions this activity
will continue through the morning hours while the western
sections of Puerto Rico will observe mostly sunny skies with no
shower activity. As the surface perturbation moves across the
region, local and diurnal effects will aid in the development of
another round of showers and thunderstorms across the interior and
northwest quadrant of Puerto Rico during the afternoon hours.
Periods of heavy showers and isolated thunderstorms can also be
expected downwind from El Yunque into the San Juan Metro area and
north-central PR.

The TUTT will weaken as it moves slowly northeastward, allowing
the intrusion of a drier and more stable air mass at mid to upper
levels by late this afternoon into the upcoming weekend.
Although upper-level dynamics will diminish, at low-levels plenty
of tropical moisture will aid in the development of overnight and
early morning showers across E-PR/USVI followed by afternoon
convection across interior/western PR each day. It is important to
point out that the coverage of this activity will be less than in
previous days.

.LONG TERM...Sunday through Thursday...

Mid-level ridge will influence the weather pattern through at
least Tuesday. This will serve to limit the potential for
organized and widespread deep convection across the region. Low-
level moisture, however, will be sufficient to the point that the
threat of showers will continue to exist. Therefore, expect brief
trade wind showers across portions of eastern PR and the USVI
during the overnight and early morning hours followed by the
development of afternoon shower and isolated thunderstorm activity
across interior and western portions of Puerto Rico due to local
and diurnal effects.

Model guidance continues to depict a wetter weather pattern to
envelop the forecast area by the middle to latter half of next week
as a trough pattern settles in over the area. This will serve to
increase the instability aloft as well as moisture pooling due to
a moist southeasterly flow. Therefore, an increase in shower and
thunderstorm activity can be expected across the region if the
current model trend continues to hold.

&&

.AVIATION...VFR conds is expected most of the time. However, passing
SHRA/+SHRA could affect NE-PR/USVI/Leeward islands terminals to
create SCT-BKN lyrs nr FL025-FL090 at times through at least 08/15z.
Then SHRA/TSRA will develop across the interior/NW-PR and in the
VCTY of TJSJ between 08/16-23z. TEMPOs could be required later this
morning as MVFR conds at TJBQ/TJMZ due to SHRA/TSRA are likely. Calm
to light-VRB winds will continue through at least 08/13z, increasing
at 10-15 kt from E-ESE with sea breeze variations.

&&

.MARINE...Seas up to 6 feet will continue across the northern
portions of the offshore Atlantic waters through this morning.
Seas of 3 to 5 feet are expected across the rest of the regional
waters. Seas are expected to increase above 7 feet across the
offshore Atlantic waters by early next week as winds increase to
near 20 knots. A moderate risk of rip currents continues for the
north facing beaches of Puerto Rico, Culebra and Saint Thomas and
across the north and east facing beaches of Vieques and Saint
Croix.
