AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
255 PM AST WED DEC 10 2014

.SYNOPSIS...COLD FRONT CONTINUED TO MOVE EASTWARDS ACROSS THE WESTERN
ATLANTIC AND EXTENDS SOUTHWARDS ACROSS EASTERN CUBA...THEN INTO THE
NORTHWESTERN CARIBBEAN. FRONT IS TO GRADUALLY WEAKEN WITH ASSOCIATED
SHEAR LINE TO STALL NORTH OF THE REGION OVER THE NEXT FEW DAYS.
SURFACE HIGH PRESSURE RIDGE EAST AND NORTHEAST OF THE REGION TODAY
WILL GRADUALLY BUILD EASTWARD ACROSS THE FORECAST AREA OVER THE NEXT
FEW DAYS. THIS WILL RESULT IN A SLIGHT INCREASE IN THE EASTERLY TRADE
WINDS DURING THE REST OF THE WORK WEEK. IN THE MEANTIME...A LIGHT EAST
SOUTHEAST WIND FLOW PREVAILED ACROSS THE REGION TODAY. IN THE UPPER
LEVELS...BROAD HIGH PRESSURE RIDGE EXTENDING ACROSS THE REGION WILL
REMAIN IN PLACE THROUGH THE UPCOMING WEEKEND.

&&

.DISCUSSION...MOSTLY FAIR WEATHER CONTINUE TO PREVAIL ACROSS THE
REGION WITH PLEASANT SEASONAL AFTERNOON TEMPERATURES. A FEW SHOWERS
FORMED ACROSS PARTS OF THE INTERIOR AND EAST COASTAL SECTION OF
PUERTO RICO DURING THE AFTERNOON... BUT MOST WERE OF SHORT DURATION
WITH NO SIGNIFICANT RAINFALL ACCUMULATIONS OBSERVED OR REPORTED.
SATELLITE IMAGERY SHOWED MOSTLY THIN HIGH LEVEL CLOUDS STREAMING
WEST ACROSS THE REGION...WHILE FEW SHALLOW LOW LEVEL CLOUDS FORMED
AND MOVED EASTWARD ACROSS THE ISLANDS AND SURROUNDING WATERS IN
THE PREVAILING WIND FLOW. RECENT TJSJ 09/12Z UPPER AIR SOUNDING

PASSING SHOWER EXPECTED OVER THE COASTAL WATERS...WHILE GRADUAL
CLEARING CAN BE EXPECTED OVER LAND. MOSTLY FAIR WEATHER SKIES
EXPECTED ON THURSDAY HOWEVER SLIGHT INCREASE IN EASTERLY TRADE
WINDS WILL BRINGS PATCHES OF TRADE WIND MOISTURE ACROSS THE REGION.
THIS WILL AID IN SOME LOCALLY AND DIURNALLY INDUCED AFTERNOON CONVECTION
MAINLY OVER PARTS OF THE INTERIOR AND WEST SECTIONS OF PUERTO RICO.
ELSEWHERE AND OVER THE VIRGIN ISLANDS...MOSTLY FAIR WEATHER SKIES WILL
PREVAIL.

SO FAR BASED ON LATEST MODEL GUIDANCE...NO SIGNIFICANT WEATHER
FEATURE IN SIGHT AT LEAST THOUGH THE UPCOMING WEEKEND...HOWEVER BY
EARLY NEXT WEEK...A SHORT WAVE TROUGH AND A FRONTAL SHEAR LINE IS
TO APPROACH THE REGION AND BRING AN INCREASE IN INSTABILITY AND
MOISTURE TO THE REGION...THUS INCREASING THE CHANCES FOR SHOWERS
AND POSSIBLY ISOLATED THUNDERSTORMS ACTIVITY ACROSS THE FORECAST
AREA. MORE TO COME ON THIS LATER AND WILL CONTINUE TO SEE HOW THIS
PATTERN UNFOLDS.

&&

.AVIATION...VFR CONDITIONS WILL CONTINUE THROUGH THE NEXT 24 HOURS
