DISCUSSION:   PARTLY CLOUDY SKIES PREVAILED ACROSS THE LEEWARD ISLANDS AND BRITISH VIRGIN ISLANDS THIS MORNING, AS THE SUBSIDENCE PATTERN CONTINUES. MEANWHILE SURFACE AND UPPER AIR ANALYSES PLACE A TROPICAL WAVE JUST EAST OF THE EASTERN CARIBBEAN. THE TROPICAL WAVE WILL BEGIN TO AFFET THE ISLANDS BY TONIGHT WHERE A HIGH CHANCE FOR CLOUDINESS AND SHOWERS ARE LIKELY. THERE IS SUPPORT FOR ENHANCEMENT AT THE MIDDLE AND UPPER LEVELS OF THE ATMOSPHERE ACROSS THE LEEWARD ISLANDS AND BRITISH VIRGIN ISLANDS, AND FOR THIS THE POSSIBILITY, THOUGH LOW EXISTS FOR THUNDERSTORMS WITH THE PASSAGE OF THE WAVE. LATEST MODEL OUTPUT IS ALONG THE LINES OF THE PREVIOUS FORECAST, WITH THE EXCEPTION THAT THERE IS A SLIGHT CHANCE OF THUNDERSTORMS.
