This is about the best description of anyone yet. AS FOR FRANCES...JUST WHEN THE MEDIUM RANGE SOLUTIONS APPEARED TO CONVERGE...OFF IN THEIR OWN WORLD THEY GO ONCE AGAIN. AS OF THIS WRITING...THE ETA...CANADIAN AND NOW NAVY NOGAPS MODELS WERE FARTHEST SOUTH. THE ETA HAS FRANCES ENTERING THE STRAITS BY 12Z/FRI WHILE THE CANADIAN/NOGAPS STEADILY MOVE IT ACROSS THE PENINSULA FROM SE TO NW ON SATURDAY. MEANWHILE...THE 00Z UKMET THRU 72H APPEARS ON TRACK WITH THE CURRENT TPC FCST. THE BIG CHANGE...AS WAS THE CASE THIS TIME YESTERDAY...IS THE GFS WHICH FIRST SLOWS FRANCES TO A CRAWL OVER THE CENTRAL/N BAHAMAS BEFORE TAKING A DUE N MOTION INTO THE SE U.S. (CAROLINAS). ALSO JUST LIKE YESTERDAY...THE GFDL IS IN VERY GOOD AGREEMENT WITH THE GFS. THIS TIME...THE KEY PLAYER IS WHETHER A WEAKNESS IN THE WESTERN ATLC RIDGE DEVELOPS OVER FLORIDA AND THE WESTERN BAHAMAS ON FRIDAY WHICH WOULD ALLOW FRANCES TO PULL UP AND WAIT FOR THE SYSTEM IN THE GULF OF AK TO EJECT INTO THE NORTHERN ROCKIES AND EVENTUALLY THE GREAT PLAINS...WHERE DEEPENING AMPLITUDE INCREASES S/SW FLOW THAT EVENTUALLY (BY SAT NIGHT OR SO) PICKS UP THE CYCLONE. THE GFS/GFDL SHOW THIS WEAKNESS WHILE THE ETA/NOGAPS/UKMET DO NOT. SO...SHOULD FRANCES BARELY SLOW DOWN...THE FARTHER S SOLUTIONS (MORE OMINOUS FOR FLORIDA) LOOK BEST. BUT...IF FRANCES SLOWS TO A CRAWL WHILE IN THE BAHAMAS...THE CHANCES FOR A FLORIDA LANDFALL DECREASE DRAMATICALLY. HOPEFULLY...WE'LL BE ABLE TO HONE IN ON A SOLUTION THIS TIME TOMORROW...ESPECIALLY SINCE THE HOLIDAY WEEKEND WILL BE "IN SIGHT". STAY TUNED... |
