Also note this:

MIDDLE/UPPER LEVEL SYNOPTIC FEATURES...

GULF OF MEXICO AND WESTERN ATLANTIC...
THE UPPER LEVEL TROUGH OVER THE CENTRAL UNITED STATES AND THE
UPPER LEVEL LOW OFF THE SOUTH CAROLINA COAST HAVE MOVED LITTLE
SINCE LAST NIGHT...AND SO NOT MUCH HAS CHANGED IN THE OVERALL
PATTERN. THE CNTRL U.S. TROUGH HAS BECOME A LITTLE
DEEPER...HOWEVER...AND NOW A LARGE AREA OF DRY AIR NOW OVER
NORTHERN MEXICO AND THE SOUTHWEST U.S. IS TRYING TO MAKE ITS WAY
INTO THE GULF. THE UPPER LOW OFF THE SOUTH CAROLINA COAST IS
CURRENTLY POSITIONED NEAR 33N78W WITH A VERY SLUGGISH NWD DRIFT.
A WEAKENING RIDGE IS LOCATED BETWEEN THESE TWO FEATURES OVER THE
GULF COAST ALONG 26N86W 34N87W BUT THERE IS ALSO A WEAK TROUGH
TRAPPED WITHIN THE RIDGE TO THE S...ALONG 21N87W 28N88W...ALMOST
CHARACTERISTIC OF A "MINI OMEGA BLOCK". TO THE E OVER THE WRN
ATLC...HURRICANE ISABEL CONTINUES TO MOVE WNW ALONG THE SRN
PERIPHERY OF A DEEP-LAYERED ANTICYCLONE...BUT THE UPPER LEVEL
SIGNATURE HAS WEAKENED CONSIDERABLY AND NOW ONLY A SMALL CLOSED
ANTICYCLONE IS CENTERED NEAR 31N62W. OVER THE NEXT 48 HRS...THE
UPPER LOW OFF THE SOUTH CAROLINA COAST IS FORECAST TO EVENTUALLY
MOVE NWD AND BECOME INCORPORATED INTO THE MUCH LARGER TROUGH
MOVING E ACROSS THE UNITED STATES. AT THIS POINT...A LARGE BUT
LOW-AMPLITUDE TROUGH PATTERN WILL BE LOCATED OVER THE EASTERN
U.S. BY TUESDAY AND THIS WILL BE ONE OF THE MAJOR FACTORS IN
STEERING ISABEL TO THE NW.
