DISCUSSION:   RELATIVELY STABLE CONDITIONS PREVAILED OVER THE AREA TODAY. FOR THIS REASON, SKIES WERE GENERALLY PARTLY CLOUDY WITH A FEW LIGHT SHOWERS CAUSED BY THE MODERATE BREEZE TRANSPORTING SHALLOW POCKETS OVER THE ISLANDS. WHILE THE CURRENT SATELLITE IMAGERY DOES NOT SHOW ANYTHING OF SIGNIFICANCE, MIMIC PRECIPITABLE WATER PRODUCT SHOW MOISTURE IN ASSOCIATION WITH A TROPICAL WAVE APPROACHING THE ISLANDS FROM THE EAST.

FOR THE NEXT 24 HOURS: THE WAVE IS FORECAST TO MOVE TO THE WEST; HOWEVER, THE GFS AND ECMWF DOES NOT HAVE A WELL-DEFINED WAVE SIGNATURE. IN FACT, THESE TWO MODELS REVEAL THAT THE WAVE WILL BE EMBEDDED IN A BROAD SYNOPTIC RIDGE PATTERN WITH LITTLE DEEP LAYERED SUPPORT. HOWEVER, ITS THE MOISTURE AND RELATED INSTABILITY THAT THIS FEATURE WILL BRING. THE AXIS OF THE WAVE COULD BE IN OUR VICINITY BY TOMORROW EVENING; HOWEVER, AN INCREASE IN MOISTURE IS FORECAST TO TAKE PLACE OVER THE LEEWARDS BEGINNING TONIGHT. THE MOISTURE, WARMER DAYTIME TEMPERATURES AND THE INSTABILITY, WILL BE THE MAIN TRIGGERS AND AS SUCH, A HEIGHTENED CHANCE OF SHOWERS IS FORECAST IN SUPPORT OF THE LATEST ISSUED FORECAST BEGINNING TOMORROW AFTERNOON INTO THE EVENING. OUT OF RESPECT FOR THE INSTABILITY, A SLIGHT CHANCE OF A THUNDERSTORM IS ALSO POSSIBLE
