AREA FORECAST DISCUSSION
FOR THE LEEWARD ISLANDS AND BRITISH VIRGIN ISLANDS
ISSUED BY ANTIGUA AND BARBUDA METEOROLOGICAL SERVICES

16:22 UTC MAY 27 2018

 

DISCUSSION: CLOUDY CONDITIONS WITH PERIODIC SHOWERS PREVAILED MAINLY ACROSS THE EASTERN ADJACENT COASTAL WATERS THIS MORNING. A FEW POCKETS HOWEVER MOVED ACROSS ANTIGUA AND BARBUDA DURING THE EARLIER PART OF THE MORNING WITH CONDITIONS IMPROVING AS THE DAY PROGRESSED. VIA SATELLITE IMAGERY SOME BLOW UPS COULD BE SEEN EAST OF BARBUDA AND THESE COINCIDED WITH THE AREA OF STRONGEST PVA ASSOCIATED WITH THE UPPER LEVEL TROUGH. THE SURFACE TROUGH IS EXPECTED TO CONTINUE WESTWARD AND WILL SUBSEQUENTLY MOVE UNDER AN AREA OF UPPER LEVEL CONVERGENCE.

MODEL GUIDANCE SUGGESTS HOWEVER, THAT FROM ST. KITTS WESTWARD COULD STILL SEE SHOWERS PASSING THROUGH THROUGHOUT THE DAY. THE SURFACE HIGH PRESSURE IS EXPECTED TO GRADUALLY BUILD ONCE AGAIN BUT NOTWITHSTANDING, LINGERING INSTABILITY AND MOISTURE COULD STILL SEE A FEW SHOWERS PASSING THROUGH MAINLY TONIGHT.
