A SHORTWAVE TROUGH IS ENTERING THE NW PORTION OF THE BASIN
ENHANCING CONVECTION N OF 24N AND W OF 92W. ACROSS THE REMAINDER
OF THE BASIN...A SURFACE RIDGE PREVAILS ANCHORED BY A 1017 MB
HIGH CENTERED OVER THE NE GULF NEAR 30N87W. FAIR WEATHER
PREVAILS ACROSS THE GULF AS STRONG SUBSIDENCE ALOFT DOMINATES
THE AREA. SCATTEROMETER DATA DEPICTS A GENTLE TO MODERATE
ANTICYCLONIC FLOW ACROSS THE BASIN. OVER THE NEXT 24
