Area Forecast Discussion
National Weather Service San Juan PR
427 PM AST Sat Apr 22 2017

.SYNOPSIS...
A ridge aloft continues to erode as an upper level short wave
trough swing by the region today and Sunday. A subtropical jet
will hold aloft through the weekend. A polar trough is forecast
to move over the Western Atlantic Ocean early next week, then will
reach the islands by early next week into mid-week. As this trough
amplifies over the region, local instability will increase each
day. Also at low levels, moisture will pull over the islands
increasing the chance for shower and thunderstorm development
beginning tomorrow through the upcoming mid week.

&&

.SHORT TERM...
Shower activity began to develop across the interior and western
sections of Puerto Rico late this afternoon. This locally and
diurnally induced afternoon convection will continue through
sunset over these areas. In addition, satellite imagery showed
streamers from the U.S. Virgin Islands, indicating the
possibility of isolated shower activity downwind from these
islands. Nevertheless, mostly sunny skies should prevail
elsewhere.

Precipitable water and local instability are expected to increase
by tomorrow, resulting in a better chance of showers and even
thunderstorms development across the interior and northern
sections of Puerto Rico. On the other hand, the U.S. Virgin
Islands should expect mostly sunny skies with just a few passing
showers.

By the upcoming week, an upper level trough with low level
convergence will combine with plenty of tropical moisture to
create an unstable and wet atmosphere over the islands. As a
result widespread showers and thunderstorms are possible across
the islands through midweek.

.LONG TERM...from previous discussion.
Tuesday through Monday... An upper level trough and an associated
surface low is expected to develop across the western Atlantic
early in the upcoming week. This will result in a significant
increase in moisture across the northeast Caribbean. In fact, PWAT
values will increase up to 2.20 inches early in the upcoming week
and until at least early Wednesday. A surface high pressure is
expected to drift northeast toward the central Atlantic early
during the upcoming week. As this happens, the local winds will
shift from the southeast. This change in wind direction will bring
a moist and very unstable tropical moisture across the region
from the southeast Caribbean. This moisture will continue to
result in a significant increase in shower and thunderstorm
activity across the region until at least early Wednesday. With
the ground across Puerto Rico still saturated from previous days
rainfall, urban and small stream flooding and possible river
flooding is likely to Monday Afternoon and Tuesday. Weather
conditions will slowly improve on Thursday as the local winds
shift eastward. Due to expected southeast wind flow, warmer than
normal temperatures are expected especially along the northern
coastal municipalities of Puerto Rico Tuesday and Wednesday.

&&

.AVIATION...
VFR conds expected to prevail across all terminals.
Cloudiness with SCT-BKN clds nr FL025...FL050...diurnally induced
afternoon SHRA will cont across parts of the ctrl interior and
