AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JUAN PR 352 PM AST SUN JUN 24 2007 .SYNOPSIS...AT UPPER LEVELS...A TROUGH IS MOVING ACROSS CUBA TONIGHT AS A WEAK RIDGE OF HIGH PRESSURE MOVES SLOWLY EAST ACROSS THE U.S. VIRGIN ISLANDS. WINDS ARE LIGHT OVER THE FORECAST AREA. THE TROUGH WILL ROTATE INTO THE DOMINICAN REPUBLIC ON MONDAY AND BE REPLACED BY HIGH PRESSURE WHICH WILL SPREAD OVER THE ENTIRE CARIBBEAN LATER IN THE WEEK. BY THE END OF THE WEEK LOW PRESSURE WILL DIG DOWN INTO PUERTO RICO AND THE U.S. VIRGIN ISLANDS WHILE HIGH PRESSURE REMAINS OVER THE WESTERN CARIBBEAN. AT MID LEVELS...THE RIDGE THAT EXTENDS FROM A HIGH IN THE CENTRAL ATLANTIC TODAY WILL BE REPLACED BY A RIDGE FROM A HIGH TO BE FOUND OVER THE WESTERN ATLANTIC BY WEDNESDAY WHICH WILL BE REPLACED BY A RIDGE FROM THE EAST BY FRIDAY...BUT GRADIENTS WILL BE GENTLE MOST OF THE TIME. AT LOW LEVELS...THE WAVE NOW AT 59 WEST WILL PASS THROUGH PUERTO RICO AROUND 18Z MONDAY. IT WILL BE FOLLOWED BY A LAYER OF DUST TUESDAY AND SOME WEAK DISTURBANCES FROM THE EAST WEDNESDAY AND THURSDAY. SEVERAL RIPPLES IN THE FLOW ACCOMPANIED BY MOISTURE ARE ALSO EXPECTED SATURDAY AND SUNDAY AND TUESDAY. && .DISCUSSION...THE TROUGH PASSAGE WAS WELL NOTICED TODAY AS SHOWERS AND THUNDERSTORMS BRUSHED BY THE U.S. VIRGIN ISLANDS AND ERUPTED ACROSS INTERIOR PUERTO RICO WITH 1 TO 3 INCHES OF RAIN AS ESTIMATED BY BIAS-ADJUSTED RADAR. THE SATELLITE PICTURE REVEALS A DRYER AREA APPROACHING SLOWLY NOW BETWEEN SAINT CROIX AND THE SOUTHERN LEEWARD ISLANDS. THE EDGE OF THE NEXT WAVE MAY NOW BE UPON THE WINDWARD ISLANDS WITH THE AXIS NEAR 58 WEST...HOWEVER THIS WAVE...DEPICTED WITH A WIND SURGE ACCOMPANIED BY VEERING AT 700 MB IN THE GFS...IS NOT PARTICULARLY ACTIVE SO THERE IS LITTLE CLOUDINESS INCREASE NOTED NEAR THE WAVE BEFORE THE NEXT AREA OF AFRICAN DUST APPROACHES...THE LEADING EDGE OF WHICH IS CURRENTLY NEAR 55 WEST. THIS MAY ALSO CAUSE TEMPERATURE ON THE NORTH COAST TO BE ENHANCED MONDAY OVER PREVIOUS FORECASTS. SINCE THE BACK EDGE OF THE DUST IS ALSO VISIBLE...ABOUT 12 DEGREES OF LONGITUDE EAST OF THE LEADING EDGE...HAVE ENDED THE HAZE ON WEDNESDAY EVENING. THE PATTERN IS NO LONGER CLEAR CUT...THE WAVES ARE NOT AS STRONGLY DEPICTED AS THEY ROLL ACROSS THE AREA AND THERE IS AN INTERPLAY BETWEEN THE SOUTHERN PORTION OF THE WAVES AND THE NORTHERN VORTICITY CENTERS COMING OFF OF AFRICA. THIS WILL KEEP THE CHANCE OF SHOWERS IN THE FORECAST MAINLY SCATTERED...WITH NO STRONG EVENTS EXPECTED AND A DEFINITE DAMPENING OF CONVECTION DURING THE PERIOD OF DUST. THE NEXT STRONGEST BAND OF MOISTURE APPEARS TO BE ON SATURDAY AS SOUTHEAST FLOW SETS UP FOR THE SECOND TIME AT 700 MB OVER THE LOCAL AREA AND A DISTINCT BACK EDGE OF THE MOISTURE APPEARS ON SUNDAY. THIS IS FOLLOWED ON TUESDAY BY MOISTURE FROM THE EAST NORTHEAST. IN THE MEANTIME GENERALLY ABOVE NORMAL TEMPERATURES WILL DRIVE STRONG THUNDERSTORMS IN THE INTERIOR FOR MOST OF THE WEEK. && .MARINE...WINDS AND SEAS HAVE BEEN TONED DOWN IN THE FORECAST DUE TO THE APPARENT LACK OF STRONG WINDS AS ADVERTISED BY THE GFS. WIND WILL INCREASE FROM THEIR CURRENT LEVELS OF 9 TO 15 KNOTS...BUT SMALL CRAFT CRITERIA WILL ONLY BE MET IN A SCATTERING OF PLACES ACROSS THE OUTER WATERS MONDAY AND TUESDAY...MAINLY DUE TO SEAS APPROACHING 7 FEET. STRONGER WINDS WELL EAST OF THE AREA...AS SEEN ON QUIKSCAT...WILL GENERATE SOME WAVE ACTION THAT WILL AFFECT THE LOCAL AREA TUESDAY...AND SLOWLY SUBSIDE ON WEDNESDAY THROUGH FRIDAY. && .AVIATION...AFTERNOON CONVECTION WILL BE CONSIDERABLE ON MONDAY IN WESTERN INTERIOR PUERTO RICO...AND TO SOME EXTENT FROM STREAMERS OFF OF EL YUNQUE AND ISLANDS EAST OF THE AREA...DUE TO THE MOISTURE ACCOMPANYING THE WAVE...BUT WIDESPREAD SHOWERS ARE NOT EXPECTED AND THE GFS HAS EVEN BACKED OFF A LITTLE ON THE MOISTURE EXPECTED FROM PREVIOUS RUNS AT 850 MB. DUE TO SATELLITE INDICATIONS OF WAVE WEAKNESS...WILL KEEP SCATTERED POPS FOR MOST AREAS MONDAY EXCEPT WHERE NORMAL HEAT AND CONVERGENCE GENERATED THUNDERSTORMS WOULD OCCUR. DUST WILL RETURN ON TUESDAY...BUT SOME AMELIORATION MAY BE HAD BY SUBSEQUENT MOISTURE BEARING DISTURBANCES FOLLOWING ON WEDNESDAY AND THURSDAY. VISIBILITIES MAY APPROACH 6 MILES IN SOME AREAS ACROSS THE CARIBBEAN. && .SJU WATCHES/WARNINGS/ADVISORIES... PR...NONE. VI...NONE. && 10/12
