DISCUSSION:   IN THE WAKE OF A TROPICAL WAVE, LINGERING MOISTURE AND INSTABILITY SAW LIGHT SHOWERS ACROSS MONTSERRAT AND NEVIS DURING THE EARLIER PART OF TONIGHT. THEREAFTER AND FOR THE REST OF THE FORECAST AREA, SHOWERS WERE SCARCE AS THE ATMOSPHERE MOVED TO SETTLE ITSELF.

NOTWITHSTANDING GOOD UPPER LEVEL SUPPORT, PRESENTLY, THE MOISTURE AT THE LOWER LEVELS IS FADING AND AN ANTICYCLONIC FLOW AT 500 MB IS CONTRIBUTING COLD AIR ADVECTION. THIS MEANS THEREFORE, A GENERALLY SETTLED ATMOSPHERE IS EXPECTED TO PREVAIL FOR THE REMAINDER OF THE FORECAST PERIOD WITH MINIMAL SHOWER ACTIVITY POSSIBLE. ADDITONALLY, LOW CONCENTRATIONS OF SAHARAN DUST REMAIN OVER THE AREA.
