SERN GA COAST...
...NE FL THROUGH SE GA...
THE CENTER OF TROPICAL STORM FAY IS LOCATED JUST OFF THE CNTRL FL
COAST NNE OF CAPE CANAVERAL AND IS FORECAST TO BEGIN A VERY SLOW
NW OR WNW MOVEMENT TONIGHT. SEE LATEST NHC DISCUSSIONS FOR FURTHER
DETAILS. WILL MAINTAIN A LOW END SLIGHT RISK FROM THE NE FL THROUGH
SE GA COAST...MAINLY FOR LATER TONIGHT GIVEN POSSIBILITY FOR LOW
LEVEL SHEAR TO INCREASE AS THE CENTER MOVES NWWD. POTENTIAL WILL
EXIST FOR LOW TOPPED SUPERCELLS TO DEVELOP OVER THE GULF STREAM AND
MOVE ONTO THE COAST. HOWEVER...THE SLOW MOVEMENT OF FAY SHOULD KEEP
THE MOST FAVORABLE NERN QUADRANT FOR ISOLATED TORNADO DEVELOPMENT
OFFSHORE THE REST OF TONIGHT. THIS ALONG WITH WEAK INSTABILITY
SUGGEST OVERALL THREAT WILL REMAIN SOMEWHAT LIMITED.
...SRN CO THROUGH CNTRL NM AND FAR W TX...
EVENING UPPER AIR DATA FROM EL PASO AND ALBUQUERQUE SHOW STEEP LAPSE
RATES THROUGH A DEEP LAYER AND INVERTED-V BOUNDARY LAYERS. STORMS
DEVELOPING OVER THE HIGHER TERRAIN ARE SPREADING SSEWD WITH MODEST
NWLY FLOW ALOFT. STRONGER STORMS WILL REMAIN CAPABLE OF PRODUCING
ISOLATED DAMAGING WIND AND HAIL THROUGH MID EVENING BEFORE
DIMINISHING WITH ONSET OF NOCTURNAL COOLING.
