AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1029 AM AST TUE JUL 27 2010

.DISCUSSION...

WITH THE SLIGHT INCREASE IN PRECIPITABLE WATER (1.61 INCH) ON 12Z
SJU RAOB...AND LESS OF A CAP TO BREAK VS. LAST COUPLE OF DAYS...
EXPECT AN EASIER TIME FOR DEVELOPING AFTERNOON SHOWERS/THUNDERSTORMS.
BUT ISOLATED TO SCATTERED AS INDICATED IN GRAPHICAL AND TEXT
FORECASTS LOOKS GOOD AND WILL LEAVE THEM AS IS. NO SUBSTANTIAL
INCREASE IN MOISTURE IS EXPECTED UNTIL THE TROPICAL WAVE AND SURGE
OF DEEP MOISTURE APPROACHES...CURRENTLY SOUTHEAST OF WINDWARD ISLANDS.

&&

.AVIATION...

NO SIGNIFICANT CHANGES ARE EXPECTED WITH 18Z TAFS. CURRENTLY SHRA
ARE MAINLY PASSING OVER THE CARIBBEAN WATERS AND DEVELOPING
DOWNSTREAM OF VIEQUES AND ST. CROIX. BUT AN INCREASE IN CONVECTIVE
CLOUDS ARE NOTED FOR MOST OTHER ISLANDS AS WELL...TYPICAL FOR THE
TIME OF DAY. MOSTLY VFR EXPECTED TO CONTINUE BUT A HIGHER CHANCE
OF SHRA/TSRA FOR WESTERN PR MOUNTAINS ALONG WITH ASSOCIATED
OBSCURATIONS.

&&

.PREV DISCUSSION... /ISSUED 452 AM AST TUE JUL 27 2010/

SYNOPSIS...AN UPPER LEVEL TROUGH WILL CONTINUE TO MOVE ACROSS THE
LOCAL REGION TODAY. A TROPICAL WAVE ALONG 58 WEST THIS MORNING WILL
CONTINUE TO TRACK WESTWARD APPROACHING TO THE LOCAL ISLANDS
WEDNESDAY NIGHT THROUGH THURSDAY.

DISCUSSION...THE DOPPLER WEATHER RADAR DETECTED SCATTERED SHOWERS
AND A FEW ISOLATED THUNDERSTORMS MAINLY ACROSS THE SURROUNDING
COASTAL WATERS OVERNIGHT AND EARLY THIS MORNING. UNDER A PREVAILING
EAST NORTHEAST WIND FLOW...SOME OF THESE SHOWERS AFFECTED THE
NORTHERN AND EASTERN SECTIONS OF PUERTO RICO. HOWEVER...DUE TO THE
RAPID MOVEMENT OF THE SHOWERS THE TOTAL RAINFALL AMOUNTS ASSOCIATED
WITH THIS ACTIVITY WERE GENERALLY MINIMAL.

A GENERALLY DRY AND PLEASANT MORNING IS EXPECTED TODAY...WITH
PLENTIFUL OF SUNSHINE. HOWEVER...FOR THIS AFTERNOON...THE
COMBINATION OF INCREASING CLOUDINESS...DAYTIME HEATING WITH LOCAL
TERRAIN EFFECTS...ENHANCED BY THE PRESENCE OF AN UPPER LEVEL TROUGH
JUST ACROSS THE REGION...WILL INDUCE THE DEVELOPMENT OF SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS MAINLY ACROSS INTERIOR AND
SOUTHWESTERN SECTIONS OF PUERTO RICO. A TROPICAL WAVE AND ASSOCIATED
SIGNIFICANT SURGE OF MOISTURE...ALONG 58 WEST THIS MORNING...IS
STILL EXPECTED TO MOVE ACROSS THE LOCAL AREA TOMORROW NIGHT THROUGH
THURSDAY...PRODUCING ANOTHER PERIOD OF CLOUDINESS...SHOWERS AND A
FEW THUNDERSTORMS ACROSS THE LOCAL ISLANDS. MIMIC-TPW FROM CIMSS
SUGGESTS THAT THE BULK OF THE MOISTURE ASSOCIATED WITH THIS TROPICAL
WAVE WILL PASS MAINLY SOUTH OF THE LOCAL ISLANDS. ANOTHER STRONGER
TROPICAL WAVE IS STILL EXPECTED FOR SATURDAY NIGHT AND ESPECIALLY
SUNDAY. THE GFS FORECAST SOUNDING...SUGGESTS PWAT VALUES BELOW 2.00
INCHES UNTIL EARLY THURSDAY. THESE VALUES WILL INCREASE ABOVE 2.00
INCHES LATE THURSDAY WITH THE PASSING OF A TROPICAL WAVE ACROSS THE
LOCAL ISLANDS.

AVIATION...EXPECT PREVAILING VFR CONDITIONS TO CONTINUE ACROSS MOST
OF THE LOCAL TAF SITES THROUGH 27/16Z. BRIEF MVFR CONDITIONS
EXPECTED MAINLY SOUTH OF TISX AND EASTWARD TO TNCM AND TKPK IN
PASSING SCATTERED SHRA/ISOLATED TSRA. AFTER 27/17Z TEMPO MVFR
CONDITIONS AND MOUNTAIN OBSCURATIONS EXPECTED IN THE VICNITY OF TJMZ
TJBQ AND NORTH OF TJPS IN SCATTERED SHRA/ISOLATED TSRA.

MARINE...GENERALLY EXPECT WINDS OF 18 KNOTS OR LESS AND SEAS OF
5 FEET OR LESS ACROSS THE REGIONAL WATERS THROUGH AT LEAST
WEDNESDAY.
