NO CHANGES PLANNED OTHERWISE. EC .PREVIOUS DISCUSSION...VERY LIGHT WINDS BOTH AT THE SURFACE AND ALOFT AS FLORIDA REMAINS IN THE MIDST OF A WEAKNESS IN THE MID LEVEL RIDGE EXTENDING ACROSS THE ATLANTIC AND GULF OF MEXICO. IT NOW APPEARS THAT THE TROUGH OVER FLORIDA WILL REMAIN MORE OF A FACTOR OVER THE NEXT FEW DAYS. WIND BELOW 600MB TURNING A BIT MORE OUT OF THE SOUTHWEST, AND BY TUESDAY IT SHOULD BE OUT OF THE WEST. THIS WOULD BE JUST ENOUGH OF A PUSH TO SUPPORT LIKELY POPS RIGHT UP TO THE ATLANTIC COAST...AND PERHAPS GIVE THE IMMEDIATE GULF COAST A LITTLE REPRIEVE BY TUESDAY. BOOSTED POPS TODAY AND TOMORROW TO JUST SLIGHTLY ABOVE OPERATIONAL ETA/GFS GUIDANCE. CONSIDERING THAT PWAT STAYS ABOVE 2 INCHES AND WEAK TROUGH IN THE VICINITY OF SOUTH FLORIDA, THE OPERATIONAL GFS RUN SEEMS MORE REASONABLE THAN THE DRIER ENSEMBLE MEMBERS. NOT MUCH CHANGE THROUGH THE ENTIRE WEEK AS THE UPPER LEVEL AND SURFACE PATTERN APPEARS STAGNANT. && .MARINE...LOW SEAS AND LIGHT WINDS WILL BE THE RULE FOR THE NEXT WEEK OUT ON THE AREA WATERS. && .MFL WATCHES/WARNINGS/ADVISORIES...
