THE WEAK TROUGH OVER THE LOWER MISSISSIPPI VALLEY LOOKS LIKE IT
WILL LIFT OUT OUT AND LEAVE A WEAKNESS IN THE SUBTROPICAL RIDGE NEAR
85W. ONE WORRISOME FEATURE IS THE APPROACHING TROUGH FROM THE
WEST. THIS WILL TRY TO NUDGE THE STORM A LITTLE CLOSER TO OUR
FORECAST AREA LATE IN THE PERIOD. THE LAST THING WE WANT IS FOR
IVAN TO SLOW DOWN WITH THIS TROUGH APPROACHING. THE HURRICANE
GUIDANCE IS PRETTY CONSISTENT WITH MOVING THE STORM OUT AND NOT TIL
IT GETS TO THE NORTHERN GULF DOES IVAN BEGIN TO FEEL THIS TROUGH.

THIS FORECAST DEPENDS ALMOST ENTIRELY ON THE FORECAST TRACK OF
IVAN. IF THE OFFICIAL FORECAST DEVIATES EVEN A LITTLE TO THE LEFT OR
RIGHT IT WILL HAVE A BIG IMPACT. STAY TUNED FOR CHANGES.
