LONG TERM...(SATURDAY THROUGH WEDNESDAY)...ZONAL FLOW ALOFT WILL CONTINUE INTO THE EARLY PART OF THE EXTENDED PERIOD. HOWEVER...THE MAIN BAND OF WESTERLIES WILL RETREAT TO THE NORTH A BIT WITH A FLAT RIDGE ACROSS THE CENTRAL GULF OF MEXICO. THIS WILL KEEP THE QUASI-STATIONARY SURFACE BOUNDARY...DEEPEST MOISTURE...AND FORCING TO THE NORTH AS WELL...WITH ONLY ISOLATED CONVECTION EXPECTED THROUGH MOST OF THE EXTENDED PERIOD. WITH THE ABSENCE OF CONVECTION AND ASSOCIATED CLOUD COVER...AFTERNOON TEMPERATURES ARE EXPECTED TO APPROACH 90 DEGREES AWAY FROM THE COAST THROUGH THE WEEKEND.
