DISCUSSION:   THE NORTHERN PORTION OF A TROPICAL WAVE MOVED ACROSS THE LEEWARD ISLANDS TODAY, PRODUCING PERIODS OF SHOWERS. SATELLITE IMAGERY CONFIRMED THE WAVE PROGRESSED WEST OF THE ISLANDS. HOWEVER, WITH A FAVOURABLE UPPER LEVEL ENVIRONMENT AND WARM TEMPERATURES. MEANWHILE, MODERATE CONCENTRATIONS OF SAHARAN DUST CONTINUE TO CREATE HAZY CONDITIONS AND SLIGHTLY REDUCED VISIBILITY ACROSS THE REGION. FOR THE NEXT 24 HOURS, THE TROPICAL WAVE WILL CONTINUE MOVING AWAY FROM THE LEEWARDS WHILE A RIDGE GRADUALLY REBUILDS ACROSS THE AREA. LINGERING MOISTURE MAY STILL GENERATE A FEW BRIEF PASSING SHOWERS TONIGHT; HOWEVER, INCREASING LOW LEVEL STABILITY SHOULD RESULT IN FEWER SHOWERS AND MORE SUNSHINE PARTICULARLY TOMORROW MORNING. SHALLOW CLOUD PATCHES MOVING WITHIN THE BRISK EASTERLY FLOW COULD STILL PRODUCE OCCASIONAL CLOUDY SPELLS. CONDITIONS ARE EXPECTED TO BECOME SOMEWHAT MORE UNSETTLED BY TOMORROW AFTER AN UPPER-LEVEL TROUGH INTERACTS WITH ANOTHER APPROACHING TROPICAL WAVE, INCREASING THE LIKELIHOOD OF SHOWERS AND ISOLATED THUNDERSTORMS ACROSS PORTIONS OF THE LEEWARD ISLANDS AND THE BRITISH VIRGIN ISLANDS. THIS OUTLOOK IS IN GENERAL AGREEMENT WITH THE LATEST ISSUED FORECAST AND NO CHANGE IS REQUIRED AT THIS TIME.
