GULF OF MEXICO...   

AN UPPER TROUGH COVERS THE E CONUS AND W ATLC INCLUDING THE N
GULF OF MEXICO WITH THE SUPPORTED FRONTAL BOUNDARIES IN THE W
ATLC AND NW CARIBBEAN. A SURFACE RIDGE DOMINATES THE GULF
ANCHORED BY A 1030 MB HIGH OVER E TEXAS. SW FLOW ALOFT ACROSS
THE S GULF IS ADVECTING UPPER MOISTURE ACROSS THE S GULF.
OVERCAST MULTILAYERED CLOUDS WITH ISOLATED SHOWERS ARE S OF LINE
FROM FLORIDA KEYS ALONG 23N89W TO CABO ROJO MEXICO. SURFACE
RIDGE WILL PERSIST THROUGH EARLY THIS WEEKEND WHEN THE NEXT COLD
FRONT IS EXPECTED TO MOVE ACROSS THE N GULF.

PUERTO RICO INTO THE W/CENTRAL ATLC. DRY AIR ALOFT AND STRONG
SUBSIDENCE CONTINUES TO DOMINATE THE BASIN. A QUASI-STATIONARY

GALE FORCE OFF NE COLOMBIA TONIGHT AND THU NIGHT.

A COLD FRONT W OF THE ISLAND WILL MERGE WITH THE QUASI-
STATIONARY FRONT NW HAITI THIS AFTERNOON. THE MERGED FRONT WILL
DRIFT E ACROSS THE ISLAND AND DISSIPATE THROUGH THU. MOISTURE
ASSOCIATED WITH THIS MERGED FRONT WILL BE MINIMAL BUT WILL
PERSIST THROUGH THE WEEKEND INCREASING THE CHANCES OF POSSIBLE
ISOLATED SHOWERS ACROSS THE ISLAND.
