FINAL MEDIUM RANGE DISCUSSION...

TO THE SOUTH OF THESE HIGHER LAT ANOMALIES...MID LEVEL HTS ARE
FCST TO BE NEAR NORMAL IN A FLAT RIDGE ACRS THE SRN TIER OF THE
NATION. THE STRENGTH OF THIS RIDGE AND THE DEGREE OF WEAKENESS IN
IT WL BE CRUCIAL FOR THE TRACK OF THE AREA OF TROPICAL WEATHER
INVOF THE BAHAMAS THAT MAY AFFECT FL AND THE NERN AND NCNTRL GULF
THIS PERIOD. THE MAJORITY OF THE MED RANGE GUIDANCE INDICATE THIS
LOW MOVG ACRS THE SRN PORTION OF THE FL PENINSULA AND INTO THE ERN
GULF BY LATE IN THE WEEK AS IT CONTS ON THE S SIDE OF THE WEAK UPR
RIDGE. THE GFS CONTS TO BE ON THE RT HAND SIDE OF THE MODEL SOLNS
IN SHOWING A TRACK ALONG THE EAST COAST OF FL FRI-SUN AND THEN
ALONG THE SERN COAST MON-TUE. THE ONE THING ALL THE MODELS DO
AGREE ON IS THAT THERE WL BE EVENTUAL WEAKENESS IN THIS UPR RIDGE
FROM THE STREAM OF STRONG SYSTEMS PUSHING IN THE NRN STREAM ALONG
THE U.S./CAN BORDER. THIS WOULD THEN SUPPORT A MORE NWD COMPONENT
TO THE TRACK AND POSSIBLE EFFECTS FOR THE ERN GULF COAST. THE
LATEST MED RANGE PROGS ARE FOLLOWING THE TPC PREFERRED AND MODEL
CONSENSUS SOLN...ALBEIT SLOWER...IN PUSHING ACRS SCNTRL FL
FRI-SAT (DAYS 3-4)..INTO THE ERN GULF BY SUN (DAY 5). AT THIS
POINT THE ADVERTISED WEAKNESS IN THE E-W RIDGE ALONG THE GULF
SHOULD ALLOW FOR A MORE NWD COMPONENT TO THE TRACK...WITH A
THREAT FOR THE CNTRL TO ERN GULF COASTAL AREA BY THE BEGINNNING OF
NEXT WEEK. SEE LATEST TPC DISCUSSIONS FOR LATEST UPDATES ON THIS
STORMS POTENTIAL.
