335 AM AST MON OCT 3 2005
.DISCUSSION...WEATHER CONDITIONS WILL CONTINUE VERY HUMID AND
UNSTABLE ACROSS THE LOCAL REGION THROUGH AT LEAST WEDNESDAY. THE 00Z
SOUNDING CAME IN WITH A PRECIP WATER OF 2.28 INCHES AND A LIFTED
INDEX OF -4.5. SATELLITE PICTURES ARE SHOWING A BAND OF MOISTURE
THAT EXTENDS NORTHEAST OF THE LOCAL ISLANDS. ACCORDING TO MODEL
GUIDANCE...THIS BAND OF MOISTURE WILL REMAIN JUST NORTHEAST OR
OVER THE LOCAL ISLANDS DURING THE NEXT FEW DAYS. GOOD THETA-E AND
OMEGA VALUES WILL SUPPORT THE DEVELOPMENT OF NUMEROUS SHOWERS...
HEAVY AT TIME AND SCATTERED THUNDERSTORMS OVER PARTS OF THE LOCAL
ISLANDS AND COASTAL WATERS. AS ALWAYS...WITH SHOWER AND THUNDERSTORM
ACTIVITY COMES THE CHANCE OF LOCALLY HEAVY RAIN WHICH CAN LEAD TO
AREAS OF URBAN AND SMALL STREAM FLOODING AND RIVER FLOODING. ALL
THIS WEATHER CAN BE ATTRIBUTED TO AN ELONGATED UPPER LOW LOCATED
OVER THE EASTERN CARIBBEAN EARLY THIS MORNING. AT LOW LEVEL...A
MAINLY SOUTHEAST WIND FLOW WILL PERSIST...ADVECTING CONSIDERABLE LOW
LEVEL MOISTURE OVER THE LOCAL AREA MONDAY THROUGH WEDNESDAY. AN
UPPER HIGH IS EXPECTED TO BUILD JUST NORTH OF PUERTO RICO...
BEGINNING TODAY AND WILL PUSH THE UPPER TROUGH SOUTHWESTWARD. ON
THURSDAY...WE SHOULD RETURN TO TYPICAL AFTERNOON PATTERNS THAT ARE
MORE DEPENDENT ON THE SURFACE WIND DIRECTION.
Dont leave the unbrellas if you arev going out those who live in the NE caribbean islands this week because that pesky throgh will hang around this week to provoke scattered showers heavy at times with many lighting and thunder like last night when the show of lighting and the rumble of thunder was plenty.
It would ruin the motto painted on the front..Open Some Days Closed Others.
