Area forecast discussion, May 11, 5:30 AM AST, 9 hours 55 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JUAN PR 530 AM AST WED MAY 11 2005 .DISCUSSION... A FAIRLY DIFFICULT FORECAST FOR THE NEXT SEVERAL DAYS IN THAT WHILE ALL THE ELEMENTS FOR THE POTENTIAL FOR HEAVY RAINFALL ARE SLOWLY COMING TOGETHER...I.E. THE PROXIMITY OF THE FRONTAL BOUNDARY TO THE REGION AND THE EXTENSION OF THE SUBTROPICAL JET INTO THE CARIBBEAN...THERE IS STILL A LOT OF UNCERTAINTY IN THE FORECAST. BUT ACCORDING TO THE LATEST GUIDANCE...THE DYNAMICS ARE MORE FAVORABLE FOR WIDESPREAD CONVECTION FRIDAY THROUGH SUNDAY. A BROAD AND ELONGATED SURFACE TROUGH EXTENDING FROM THE CENTRAL CARIBBEAN NORTHEAST ACROSS THE LOCAL ISLANDS IS EXPECTED TO PERSIST TODAY THROUGH THE WEEKEND. BUT BY FRIDAY...A PLUME OF COPIOUS LOW LEVEL MOISTURE IS EXPECTED TO EXTEND FROM NEAR CENTRAL AMERICA AND NORTHEASTWARD ACROSS HISPANIOLA AND INTO THE LOCAL ISLANDS. IN ADDITION...THE MODEL GUIDANCE INDICATES THAT THE DYNAMICS WILL RESULT IN LARGE SCALE SYNOPTIC LIFT EXTENDING FROM THE LOW LEVELS TO NEAR 200 MB BY LATE FRIDAY AND INTO SATURDAY AND SUNDAY. IN ADDITION THE 700 TO 850 THETA-E VALUES ARE EXPECTED TO BE INCREASING SIGNIFICANTLY AS WELL DURING THAT TIME FRAME. ONE OTHER FEATURE TO POINT OUT IS A TROPICAL WAVE NOW LOCATED NEAR 48.5 WEST...BUT THE MOISTURE ASSOCIATED WITH THAT WAVE IS EXPECTED TO REMAIN TO THE SOUTH OF THE LOCAL ISLANDS BY LATE FRIDAY INTO SATURDAY. NEED TO STRESS ONE MORE TIME THE IMPORTANCE OF THE UNCERTAINTY IN THE FORECAST. FOR EXAMPLE...FOR THE AFOREMENTIONED TROPICAL WAVE IF THERE IS A SLIGHT CHANGE IN THE FORECAST POSITION FOR LATE FRIDAY...THE SUBSIDENCE AHEAD OF THE WAVE MIGHT INFLUENCE THE LOCAL ISLANDS AND DECREASE CHANCES OF CONVECTION. IN ADDITION...IF THE AFOREMENTIONED PLUME OF COPIOUS LOW LEVEL MOISTURE EXPECTED TO EXTEND FROM NEAR CENTRAL AMERICA AND NORTHEASTWARD INTO THE REGION BY FRIDAY IS SHIFTED SLIGHTLY MORE NORTHWARD THEN THERE MAY BE LESS CHANCE OF WIDESPREAD CONVECTION. SO WILL JUST HAVE TO MONITOR THE PROGRESS OF THESE FEATURES AND CHANGE FORECAST ACCORDINGLY AS THINGS UNFOLD. && .MARINE... MODERATE LONG PERIOD NORTH SWELLS WILL CONTINUE TO AFFECT THE LOCAL WATERS THROUGH AT LEAST TODAY AND WILL CONTINUE TO GRADUALLY SUBSIDE TONIGHT INTO THURSDAY. THEREAFTER...TRANQUIL SEAS ARE EXPECTED TO PERSIST ACROSS THE REGIONAL WATERS THROUGH SATURDAY INTO SUNDAY. THE LATEST GUIDANCE SUGGESTS THAT THE SURFACE WIND SPEEDS ARE EXPECTED TO INCREASE LATE SUNDAY INTO MONDAY IN ASSOCIATION WITH A DEVELOPING SURFACE LOW FORECAST TO DEVELOP ACROSS THE REGION BY MONDAY...WITH A CORRESPONDING INCREASE IN THE LOCAL SEAS. HOWEVER AS STRESSED ABOVE THERE IS A LOT OF UNCERTAINTY IN THE LONG TERM FORECAST. && .PRELIMINARY POINT TEMPS/POPS... SJU 83 75 83 75 / 60 50 50 50 STT 83 76 82 75 / 40 50 50 50 && .SJU WATCHES/WARNINGS/ADVISORIES... .PR...NONE. .VI...NONE. && DIEHL
