LITTLE TIME FOR DISCUSSION.  WILL USE EVENING WORDING ACROSS WESTERN

STICK CLOSE TO FWC AS UPPER LEVEL RIDGE SLOWLY PUSHES OFF TO THE
EAST COAST.  WILL PUT MENTION OF AFTER TSRA BOTH THU AND FRI.  THU
DUE TO WEAK CYCLONIC FLOW OVER FA AND FRI DUE TO INCREASE IN PWS AND
RIDGE EXITING REGION.

WILL KEEP TSRA MENTIONED THROUGH EXTENDED AS TROUGH APPROACHES FROM
