Part of tally AFD... .SHORT TERM...AFTER ONE MORE DAY OF DRY CONDITIONS WITH THE RIDGE OF HIGH PRESSURE DOMINATING TO THE NE...UNSETTLED WEATHER IS ON THE WAY FOR THE WEEKEND. THERE ARE STILL SIGNIFICANT DIFFERENCES BETWEEN THE ETA AND GFS...WITH BOTH MODELS SHIFTING TO A MORE WESTWARD TRACK OF THE GULF LOW ON THE 12 UTC RUNS. AFTER BEING VERY CONSISTENT WITH AN E-NE MOVING SYSTEM ALONG THE GULF COAST...THE GFS HAS SHIFTED MUCH MORE DRAMATICALLY THAN THE ETA...AND NOW BRINGS IT NORTHWARD THROUGH LOUISIANNA. ALTHOUGH THIS SYSTEM LOOKS LIKE IT WILL EVOLVE IN A VERY BAROCLINIC MANNER...THERE IS STILL SOME POTENTIAL FOR SUB-TROPICAL DEVELOPMENT WHICH THE HURRICANE CENTER WILL BE WATCHING FOR VERY CLOSELY. SHOULD THE SYSTEM MOVE INLAND TO OUR WEST...WE WILL END UP IN THE WARM SECTOR WITH A MUCH BETTER CHANCE FOR CONVECTION WITH LESS OR A SHORTER PERIOD OF ISENTROPIC LIFT. THEREFORE...PLAN ON NUDGING THE GRIDS IN THAT DIRECTION...WHICH WILL RESULT IN LOWER POPS FOR FRIDAY NIGHT AND SATURDAY. .LONG TERM...CURRENT THINKING IS IN AGREEMENT WITH THE GFS FOR THE SYSTEM IN THE GULF OF MEXICO. THE SYSTEM WILL MOVE ALONG THE GULF COAST AND BEGIN TO AFFECT THE CWA AS EARLY AS SATURDAY...WITH A SLOW EASTWARD MOTION THEREAFTER. THEREFORE...UNSETTLED CONDITION MAY LAST INTO TUESDAY. DEPENDING ON ITS FINAL TRACK...THIS SYSTEM MAY PRODUCE LOCALLY HEAVY RAINS AND STRONG GUSTY WINDS. WILL CONTINUE TO MONITOR THIS SITUATION AS THERE IS A STRONG DISAGREEMENT BETWEEN GFS AND ETA. A STRONG COLD FRONT IS ALSO EXPECTED TO APPROACH THE CWA BY LATE NEXT WEEK...AND IT COULD USHER IN MUCH DRIER AND COOLER AIR FOR NEXT WEEKEND. |
