Area Forecast Discussion
National Weather Service San Juan PR
450 AM AST Mon Sep 21 2020
.SYNOPSIS...
Though showers are expected over the interior of Puerto Rico and
possibly the San Juan Metro, greater activity is expected for
tomorrow and Wednesday as increased moisture moves in. The biggest
story is that though the most recent swell will weaken throughout
today, another swell associated with Hurricane Teddy will arrive
tomorrow, and likely keep seas hazardous through the workweek. In
the longterm, ridging aloft will limit the strength of
thunderstorms, though showers will still be expected.
&&
.SHORT TERM...Today through Wednesday...
The islands will be under a light southerly wind flow as a result
of Teddy, which is located well off to the north of the local
islands over the Atlantic Ocean. Maximum temperatures should
remain in the low 90s across the coastal and urban areas with heat
indices in the low to mid 100s degrees Fahrenheit. At upper
levels, a TUTT-low lingering around the Northeast Caribbean will
keep a relatively unstable atmosphere through at least Tuesday.
However, a short wave trough will swing by the region by mid-week,
destabilizing the atmosphere once again.
Mostly clear skies with warm and hot temperatures will dominate
weather conditions this morning. Under a light southwesterly
steering wind-flow, afternoon convection will focus over St Croix
and across and to the northeast of the Cordillera Central,
including the San Juan Metro Area.
Moisture from the Caribbean will move over the islands on Tuesday,
increasing the potential for showers and thunderstorm development.
Then, moisture from an old frontal boundary will move from the
Atlantic Ocean over the islands, and it will interact with a short
wave trough, diurnal heating, and local effects to produce another
round of afternoon convection over the islands. Scattered showers
with possible heavy thunderstorms are possible Tuesday and
Wednesday. However, convection may change its focus on Wednesday,
as winds change more from the east-southeast.
.LONG TERM...Thursday through Tuesday...
Heading into the latter-half of the workweek, strong high pressure
will persist to our west at mid to upper levels with a cut-off
area of low pressure to our southeast. Though there will not be
much in the way of upper-level forcing to encourage thunderstorm
development, 500mb temperatures will still be decent, around -6 to
-7 for the whole long-term period. Thus, isolated thunderstorms
will be in the forecast during this period, but they ought not to
be too strong. At low levels, high pressure will primarily
persist over the eastern Atlantic, with weaker pressure gradients
over our region. Thus, fairly light winds are expected over our
region during the long-term period, so slow moving showers and
high rainfall accumulation's could be a threat. There are signs
of a strengthening high over the western to central Atlantic next
week.
Ample moisture from a weakening low will be with us for Wednesday
through Saturday. Precipitable water values will be above average of
around 1.8 to 2.0. With light winds, plenty of shower activity with
isolated thunderstorms can be expected, particularly over the
interior of Puerto Rico. The biggest threat is going to be areas of
isolated flooding under where the most persistent showers occur.
Thereafter, somewhat drier air is expected to move in, with low-
level wind speeds picking up a bit into the next week. Thus, the
next week is not expected to be as impactful given that the showers
should at least move along a bit more quickly.
&&
.AVIATION...
VFR conditions will prevail thru the forecast period. Expect
mostly clear skies with just a few passing clouds. Some
clouds/SHRA may develop during the afternoon and may impact JSJ
between 21/15-20z. Winds will remain calm to light/VRB. However,
gusty winds in/near showers, as well as sea breeze variations, are
possible.
&&
.MARINE...
The first swell associated with Hurricane Teddy will be
dissipating throughout the day. However, another swell will be
impacting the region tomorrow from the north, and this one is also
associated with Teddy. Small Craft Advisory criteria will once
again be met beginning tomorrow and this will last likely into
Friday. A High Surf Advisory may be needed as well.
