EVENT...TUTT NEARING THE LOCAL AREA
.
SATELLITE ANALYSIS AND TRENDS...LATEST SATELLITE TRENDS SHOW A TROPICAL
UPPER-TROPOSPHERIC TROUGH (TUTT) NORTH OF THE LEEWARD ISLANDS AND
MEANDERING WESTWARD TOWARD THE LOCAL FORECAST AREA. AN AREA OF COLD
CLOUD TOPS IS MOVING SOUTHWARD TOWARD SAINT THOMAS AND SAINT JOHN WHILE
SURFACE ANALYSIS SHOWS GOOD LOW-LEVEL MOISTURE WITH DEWPOINTS IN THE MID
70S. ALSO AT THE SURFACE, IN ASSOCIATION WITH THE APPROACHING TUTT, IS AN
INDUCED SURFACE TROUGH. ACCOMPANYING THE TUTT/INDUCED SURFACE TROUGH IS
A PLUME OF INCREASED MOISTURE  MOVING TO THE SOUTHWEST WITH THE BLENDED
TPW AND AMSU PW PRODUCTS SHOWING VALUES AROUND TWO INCHES. UPPER-AIR
ANALYSIS SHOWS SOME DIFFLUENCE ACROSS THE REGION HELPING TO PROVIDE MORE
FAVORABLE UPPER-LEVEL DYNAMICS TO THE AREA.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1130-1730Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...GIVEN THE PROXIMITY TO THE APPROACHING TUTT,
WITH GREAT MOISTURE AND FAVORABLE UPPER-LEVEL DYNAMICS IN PLACE, EXPECT
A CHANCE FOR SOME ISOLATED SHOWERS/CONVECTION FOR EASTERN PUERTO RICO
AND THE U.S. VIRGIN ISLANDS FOR THE REST OF THE MORNING. THIS AFTERNOON,
AS DAYTIME HEATING PEAKS, EXPECT THE THREAT TO BE MAINLY FOR CENTRAL
AND WESTERN PUERTO RICO WITH AN ISOLATED THREAT FOR SHOWERS/CONVECTION
ACROSS EASTERN PUERTO RICO, THE U.S. VIRGIN ISLANDS, AND COASTAL WATERS.
