COVERAGE AND CLOUDINESS.

&&

.DISCUSSION...PARTLY CLOUDY SKIES AND MINIMAL SHOWER ACTIVITY
PREVAILED ACROSS THE FORECAST AREA DURING THE MORNING AND EARLY
AFTERNOON HOURS. LATEST WATER VAPOR IMAGERY CONTINUES TO INDICATE
A DRIER AND STABLE AIR MASS OVER THE LOCAL AREA. ALTHOUGH...NWS
DOPPLER RADAR DETECTED ISOLATED SHOWERS ACROSS THE LOCAL
WATERS...WITH A FEW SPRINKLES NOTED OVER LAND AREAS...ESPECIALLY
ALONG THE NORTHEASTERN SECTIONS OF PUERTO RICO EARLY THIS MORNING.

LATEST GFS CONTINUES TO INDICATE A MID TO UPPER LEVEL RIDGE
EXTENDING OVER PUERTO RICO AND HISPANIOLA THROUGH TONIGHT. THIS
RIDGE PATTERN IS EXPECTED TO ERODE BY EARLY FRIDAY. HOWEVER...A
GENERALLY FAIR WEATHER PATTERN IS EXPECTED TO PREVAIL WITH LIGHT
PASSING SHOWERS ACROSS SECTIONS OF EASTERN AND NORTHERN PUERTO RICO
DURING THE OVERNIGHT AND EARLY MORNING HOURS...AS PATCHY SHALLOW
MOISTURE ADVECTS ACROSS THE LOCAL ISLANDS. BETTER CHANCES OF PASSING
SHOWERS ARE ANTICIPATED BY THE UPCOMING WEEKEND WHEN A WEAK COLD
FRONT...NOW LOCATED OVER THE BAHAMAS...IS EXPECTED TO MOVE
TOWARDS THE FORECAST AREA. THIS FRONT WILL BRING AN INCREASE IN
SHOWER COVERAGE AND CLOUDINESS ACROSS THE LOCAL ISLANDS BEGINNING
LATE SATURDAY THROUGH POSSIBLY MONDAY. BUT...BIGGER CONCERN

Good afternoon. The SNET has released the climate outlook for the next 4 months in El Salvador:

-Rainfall between December and March will be near average, that means 45 mm (1.77 inches) in the coast and valleys and 75 mm (2.95 inches) in the mountainous areas.
-Rainfall in April is expected to be near normal too, that is 29 mm (1.14 inches) for the coast and valleys and 83 mm (3.27 inches) in the mountains.
-Temperatures will be near average as well, with December, January and February being the coolest and March and April the warmest.
-12 to 14 cold fronts are expected in the period, the peak of the cold front season goes from December to February.

And finally something that I've already mentioned before is that 2010 has been the wettest year on record in El Salvador:
-Los Naranjos station has registered 3508 mm (138.11 inches) of rain when the normal rainfall is 2093 mm (82.4 inches)
-San Salvador has registered 2500 mm (98.4 inches) and the average is 1600 mm (63 inches)

This graphic shows the actual rainfall and the average rainfall between January 1 and November 10 for several stations:

[cycloneye]

The all time record of rainfall of 87.55 inches is still alive as until December 3rd,82.22 inches has fallen.Let's see if it can be reached or not,but regardless, it has been a very wet year in Puerto Rico.

.SYNOPSIS...WEAK CDFNT ACROSS THE TURKS AND CAICOS EXPECTED TO
DISSIPATE ON SUN BEFORE REACHING THE LOCAL AREA. A STRONGER CDFNT
IS EXPECTED TO STALL ACROSS THE MONA PASSAGE MIDDLE OF NEXT WEEK.


&&

.DISCUSSION...ONE MORE COOL NIGHT ON TAP BEFORE SLOW AIR MASS
MODIFICATION BEGINS TO TAKE PLACE SAT. CONTINUED DRY NEXT 24 HRS
WITH NO PRECIP EVEN OVER THE COASTAL WATERS.

WEAK CDFNT ACROSS THE TURKS AND CAICOS WILL APPROACH THE NW
COASTAL WATERS LATE SAT WITH SOME CLOUDS AND A COUPLE OF SHOWERS
ACROSS THE NW WATERS BUT NOTHING EXPECTED OVER LAND. A SLIGHT
INCREASE IN LOW-LVL MOISTURE SAT NIGHT MAY YIELD A COUPLE OF
SHRAS OVR THE USVI AND SURROUNDING WATERS BUT STILL NOTHING XPCD
OVR PR. CONTINUED DRY SUN WITH ISOLD SHRAS ONLY OVR THE COASTAL
WATERS.

MODELS HAVE TRENDED FASTER WITH DEEP MOISTURE SURGE NEXT WEEK
INDICATING 2+ INCH PW AIR WORKING ITS WAY NWD INTO THE AREA TUE
AFTERNOON. DEEP POLAR TROUGH ACROSS THE WRN ATLC WILL HELP PUSH A
STRONG CDFNT INTO THE MONA PASSAGE AND INDUCE AN INVERTED SFC TROF
PATTERN ACROSS THE AREA. MID-UPPER FLOW WILL BACK MORE TO THE
SOUTH IN RESPONSE TO FALLING HEIGHTS AND ALLOW DEEP TROPICAL
MOISTURE TO SURGE INTO THE AREA. SHORTWAVE VORTICES MOVING ACROSS
THE BASE OF THE BROAD TROF WILL RESULT IN AN UNSETTLED PERIOD TUE-
THU WITH THE POTENTIAL FOR A SIG RAINFALL EVENT ESPECIALLY OVR WRN PR.

DISSIPATE JUST NORTHWEST OF THE LOCAL ISLANDS TONIGHT AND SUNDAY.
STILL EXPECT THIS BOUNDARY TO RESULT IN A GENERAL INCREASE IN
CLOUDINESS AND A FEW SHOWERS ACROSS THE LOCAL ISLANDS...BUT SHOULD
NOT BE A BIG DEAL GIVEN THE FACT THAT BOUNDARY SHOULD REMAIN
MAINLY NORTHWEST OF THE LOCAL ISLANDS. ONLY FLY IN THE OINTMENT
HERE...WOULD BE IF FRONT ACTUALLY MADE IT DOWN ACROSS THE LOCAL

AND WOULD COME ON THE HEELS OF THIS RATHER DRY SPELL WE HAVE HAD
LATELY.

MODERATE...LONG PERIOD...NORTHEAST SWELLS WILL PEAK ACROSS THE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
230 PM AST SAT DEC 4 2010

.SYNOPSIS...AT MID AND UPPER LEVELS...SHORT WAVES WILL MOVE
THROUGH A LONG WAVE TROUGH AND LOW THAT REMAINS JUST NORTH OF THE
NORTHEAST UNITED STATES FOR THE NEXT 10 DAYS. AT THE SAME TIME
HIGH PRESSURE WILL REMAIN OVER THE TROPICAL ATLANTIC OCEAN
SOUTHEAST OF THE WINDWARD ISLANDS AT UPPER LEVELS AND EAST
AT MID LEVELS. THIS WILL KEEP MODERATE WEST SOUTHWEST FLOW AT
THOSE LEVELS.

AT LOWER LEVELS...A SHALLOW COLD FRONT IS APPROACHING PUERTO
RICO...BUT DISSIPATING AS IT DOES SO. THE TAIL OF THE FRONT IS
PASSING HISPANIOLA AND WILL ARRIVE IN LOCAL ATLANTIC WATERS
TONIGHT. HIGH PRESSURE WILL RIDGE EAST ACROSS THE ATLANTIC JUST
NORTH OF THE LOCAL AREA...BUT A TROUGH PASSING NORTH OF THE AREA
ON TUESDAY WILL ALLOW BETTER MOISTURE FROM THE TROPICAL ATLANTIC
TO PUSH IN OVER PUERTO RICO AND THE U.S. VIRGIN ISLANDS TUESDAY
INTO WEDNESDAY. BANDS AND PATCHES OF MOISTURE WILL THEN MOVE
THROUGH THE AREA IN EAST SOUTHEAST FLOW THROUGH THE REMAINDER OF
THE FORECAST PERIOD.

&&

.DISCUSSION...THE FRONTAL BAND IS CLEARLY VISIBLE IN SATELLITE
IMAGERY AND NOW PASSING NORTHEAST OF THE DOMINICAN REPUBLIC.
MODELS SHOW THE TAIL OF THE FRONT WEAKENING CONSIDERABLY AS IT
APPROACHES PUERTO RICO AND CONVERTING INTO A ZONE OF CONVERGENCE
TONIGHT AND SUNDAY. ALL INDICATIONS ARE THAT IT WILL STALL OVER
THE NORTHERN ATLANTIC WATERS AND THEN RETURN TO THE NORTHWEST
BEGINNING SUNDAY NIGHT. IT MAY SEND A BAND OF MOISTURE AS FAR AS
NORTHWEST OR NORTH CENTRAL PUERTO RICO...BUT LITTLE IS EXPECTED
BEYOND SOME ADDITIONAL CLOUDS AND ISOLATED SHOWERS. DEWPOINTS
REMAIN IN THE LOWER 60S ACROSS THE AREA AHEAD OF THE FRONT AND
BUOY 42046 NORTH OF THE BAHAMAS BEHIND THE FRONT SHOWED DEWPOINTS
IN THE MID 50S. AFTER SUNDAY NIGHT FLOW REVERSES AND AIR FROM THE
TROPICAL ATLANTIC WILL BEGIN TO PRESS IN FROM THE EAST. MOISTURE
VALUES WILL CLIMB SUNDAY NIGHT THROUGH TUESDAY. THIS WILL ALLOW A
FEW MORE SHOWERS AND BRING RELATIVE HUMIDITY UP. MOISTURE ALSO
EXTENDS UP THROUGH 400 MB TUESDAY THROUGH SATURDAY AND THIS DEEPER
LAYER WILL BRING IN MORE CLOUDS AND RAIN...BUT NOT NECESSARILY
COOLER TEMPERATURES. EAST SOUTHEAST FLOW AND WARMER AIR FROM THE
EAST WILL TEND TO COUNTERACT THE CLOUD COVER. MODELS HOWEVER SHOW
PUERTO RICO AND THE U.S. VIRGIN ISLANDS ON THE NORTHERN EDGE OF
THE MID LAYER MOISTURE AND SO A SLIGHT FLUCTUATION IN THE STRENGTH
OF THE MID AND UPPER LEVEL HIGH TO THE SOUTHEAST COULD LEAVE US
JUST OUTSIDE THAT MOISTURE...HENCE THERE IS SOME UNCERTAINTY TO
THE WETTER TREND. THE ECMWF IS WETTER OVERALL AND TAKES THE
MOISTURE FARTHER NORTH SO SCATTERED SHOWERS APPEARS TO BE VERY
REASONABLE FOR THE WINDWARD PORTIONS OF PUERTO RICO AND ALL OF THE
U.S. VIRGIN ISLANDS TUESDAY THROUGH SATURDAY.

&&

.AVIATION...CONTINUE TO EXPECT PREVAILING VFR CONDITIONS ACROSS THE
LOCAL ISLANDS AND AT ALL LOCAL TAF SITES DURING THE NEXT 24 HOURS.
HOWEVER...VERY BRIEF MVFR CONDITIONS WILL REMAIN POSSIBLE IN
ISOLATED PASSING SHOWERS AFTER MIDNIGHT. NO FLYING HAZARDS OR
OPERATIONAL WEATHER IMPACTS ANTICIPATED AT THIS TIME.

&&

.MARINE...SWELL HAVE SUBSIDED AND BUOYS SHOW SEAS BELOW 7 FEET.
TONIGHT SWELL WILL INCREASE FROM BOTH THE NORTHWEST AND THE
NORTHEAST AND SMALL CRAFT ADVISORIES WILL BE NEEDED FOR THE OUTER
ATLANTIC WATERS SUNDAY AND FOR THE ATLANTIC AND CARIBBEAN PASSAGES
BY SUNDAY NIGHT. SEAS WILL CONTINUE THERE AND EXTEND INTO THE
OUTER CARIBBEAN WATERS NEAR THE PASSAGES UNTIL AT LEAST TUESDAY NIGHT.

I bet you like those temperatures in Puerto Rico, for me this is my favorite time of year weather-wise.

I bet you like those temperatures in Puerto Rico, for me this is my favorite time of year weather-wise.

I also like those kind of temperatures as when I was a child in New York before moving to Puerto Rico,I saw plenty of snow.
