AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
521 AM AST WED MAR 19 2008

.SYNOPSIS...AT UPPER LEVELS...A MILD RIDGE BUILDS OVER THE WEST
CENTRAL CARIBBEAN AND LEANS OVER THE LOCAL AREA AS IT DECAYS
THROUGH SATURDAY. RIDGING THEN CONTINUES TO THE EAST OF THE LOCAL
AREA THROUGH THE BEGINNING OF THE UPCOMING WEEK.

AT MID LEVELS...HIGH PRESSURE OVER CUBA AND A MUCH STRONGER LOW
JUST SOUTHEAST OF NOVA SCOTIA IS SENDING MODEST NORTHWEST FLOW
OVER THE AREA. THE HIGH PRESSURE WILL SLOWLY DRIFT TO JUST
NORTHEAST OF THE LOCAL AREA BY THE WEEKEND AND WILL REMAIN
DOMINANT OVER THE AREA. THE MID LEVEL ATMOSPHERE REMAINS EXTREMELY DRY.

AT LOWER LEVELS...A COLD FRONT PUSHED THROUGH THE LOCAL AREA
YESTERDAY AND OVERNIGHT ALLOWING A COOLER AIRMASS TO POUR INTO THE
AREA. AREAS OF LOW LEVEL CLOUDS ARE FOLLOWING. HIGH PRESSURE WILL
BUILD WEAKLY OVER THE WESTERN ATLANTIC DURING THE REST OF THE
WORK WEEK AND WILL BE REINFORCED BY ANOTHER HIGH PRESSURE
MIGRATING SOUTHEAST OUT OF THE EASTERN UNITED STATES. THAT HIGH
PRESSURE WILL MOVE RAPIDLY EAST AND THEN NORTHEAST SO AS TO BE IN
THE NORTHEAST ATLANTIC BY MONDAY MORNING. DURING THE EARLY PART OF
NEXT WEEK ANOTHER SEED LOW OUT OF THE CARIBBEAN WILL GROW RAPIDLY
OVER THE WESTERN ATLANTIC AS IT MOVES QUICKLY TO THE NORTHEAST.
EASTERLY TRADE WINDS WILL PERSIST THROUGH MOST OF NEXT WEEK.

&&

.DISCUSSION...SATELLITE PICTURES REVEAL THAT A CONSIDERABLE MASS
OF CLOUDS IS PUSHING INTO THE LOCAL AREA THIS MORNING AND WILL
KEEP SKIES MOSTLY CLOUDY DURING THE DAY. THE NAM SEEMED TO HAVE A
BETTER HANDLE ON THIS THAN THE GFS FOR TODAY. BOTH MODELS SEE SOME
INCREASE IN RAIN OVERNIGHT INTO THURSDAY...BUT THE NAM BRINGS IN A
DISTINCT POCKET OF CLOUDS AND SHOWERS THAT WOULD WET MUCH OF THE
NORTHEAST THIRD OF PUERTO RICO DURING THE EARLY MORNING HOURS ON
THURSDAY. THAT SAID...THERE ARE OTHER CLUES THAT THE NAM MAY HAVE
GOOD BASIS FOR A LITTLE MORE POP ON THURSDAY MORNING THAN
PREVIOUSLY CREDITED. ALL OF THE MODELS SHOW INCREASING
PRECIPITABLE WATER THROUGH THE END OF THE WEEK. THE GFS SHOWS A
STEADILY INCREASING MOIST LAYER THROUGH SUNDAY AS RELATIVE
HUMIDITIES GREATER THAN 50 PERCENT RISE IN THE ATMOSPHERE FROM 830
MB TUESDAY NIGHT TO 670 MB SATURDAY NIGHT. THIS WILL GIVE CLOUDS
MORE ROOM TO ACTIVATE PRECIPITATION PROCESSES. THEREFORE HAVE BEEN
GENERALLY PUSHING POPS A INCREMENTALLY HIGHER THROUGH SATURDAY AT
LEAST. THIS SHOULD NOT RESULT IN WIDESPREAD CONTINUOUS RAIN...BUT
WILL KEEP CLOUDS AND SCATTERED SHOWERS AROUND THE AREA.
TEMPERATURES WILL LIKELY BOTTOM OUT 06Z ON THURSDAY WHEN A MINIMUM
1000-850 MB THICKNESS OF 1379 METERS WILL BE REACHED. BUT MANY
AREAS WILL NOT REACH THEIR LOWEST TEMPERATURES OF THE WEEK
THEN...DUE TO THE WINDS BRINGING IN AIR TEMPERED BY A TEPID
ATLANTIC.

LOW LEVEL MOISTURE NEVER REALLY DISAPPEARS...BUT THERE IS SOME
WEAKNESS IN THE UPPER HALF OF THE LOWER LEVEL RELATIVE HUMIDITY
FROM SUNDAY AFTERNOON TO EARLY TUESDAY MORNING UNTIL ANOTHER AREA
OF MOISTURE KICKS THROUGH. THICKNESSES RECOVER TO PREVIOUS LEVELS
BY MONDAY AND WE SHOULD AGAIN BE ABLE TO SEE HIGHS IN THE MID TO
UPPER 80S IN THE LOWER ELEVATIONS OF PUERTO RICO.

&&

.AVIATION...MOSTLY VFR CONDITIONS CAN BE EXPECTED ACROSS ALL THE
LOCAL TAF SITES FOR THE NEXT 24 HOURS. HOWEVER...EXPECT
SIGNIFICANT CLOUD COVER ACROSS THE REGION TODAY...WITH A BROKEN
STRATOCUMULUS DECK BETWEEN 3000 AND 5000 FEET. BRIEF MVFR
CONDITIONS...ASSOCIATED WITH ISOLATED TO SCATTERED PASSING
SHOWERS...WILL BE POSSIBLE THROUGH THE DAY...ALONG WITH OCCASIONAL
MOUNTAIN OBSCURATIONS. IN ADDITION...WINDS WILL BE GENERALLY OUT
OF THE NNE AT 10 TO 20 KNOTS...WITH OCCASIONAL GUSTS TO 30 KNOTS
NEAR SHOWERS.

&&

.MARINE...THIS HAS BEEN AN INTERESTING TIME FOR MARINE INTERESTS
IN THE LOCAL AREA. THE BUOY NORTH OF THE LOCAL AREA HAS WAVE
HEIGHTS THAT HAVE RISEN TO 12 TO 14 FEET...MOST OF WHICH IS
SWELL...BUT A CLOSER LOOK INDICATES THAT IT ALSO CONTAINS 6 FEET
OF SHORTER PERIOD WAVES. THIS COMBINATION WILL MAKE NAVIGATION
DIFFICULT IN MOST AREAS AND TREACHEROUS IN THE MORE SHALLOW PARTS
OF THE ATLANTIC AND THE PASSAGES TO THE CARIBBEAN. SWELL PERIODS
ARE RUNNING 12 TO 14 SECONDS AT THE MOMENT AND ARE FORECAST TO
INCREASE EARLY THURSDAY. THE MODEL HAS BEEN CONSISTENT WITH THE
WAVE PEAK HEIGHT AND TIME OF ARRIVAL...PLACING IT AROUND 09Z ON
THURSDAY AT AROUND 5 METERS. AS WAVES INCREASE...IT IS LIKELY
THAT THE HIGH SURF ADVISORY WILL BE UPGRADED TO A HIGH SURF
WARNING LATER TODAY. THE COASTAL FLOOD WATCH WILL CONTINUE AND
CONDITIONS ALONG THE NORTHERN SHORES OF THE ISLAND WILL BE
MONITORED CLOSELY FOR CONDITIONS THAT COULD MERIT A COASTAL FLOOD
WARNING. THIS OCEAN WILL BE INTRIGUING TO LOOK AT...BUT WILL BE
MERCILESSLY UNFORGIVING OF THOSE WHO TRY TO CHALLENGE ITS POWER.
