AREAS AFFECTED...NRN AND CNTRL AL

CONCERNING...TORNADO WATCH 97...98...

VALID 272024Z - 272230Z

INTENSIFICATION OF STORMS IS ONGOING...RISK OF TORNADOES IS
INCREASING...WITH ISOLATED STRONG TORNADOES POSSIBLE LATE THIS
AFTERNOON.  CONTINUE WWS.

INCREASING INFLUENCE OF APPROACHING SHORT WAVE TROUGH ON INSTABILITY
AXIS IS APPARENT BY NOTABLE INCREASE/INTENSIFICATION OF CONVECTIVE
ACTIVITY ACROSS MUCH OF ALABAMA.  SURFACE LOW PRESSURE CENTER TO THE
NORTHWEST OF BIRMINGHAM IS NOW BELOW 1000 MB...AND PRESSURES
CONTINUE TO FALL.  THIS FEATURE WILL PROVIDE ONE FOCUS FOR POTENTIAL
TORNADIC SUPERCELL DEVELOPMENT NEXT FEW HOURS...AS SOUTHERLY
LOW-LEVEL JET STRENGTHENS INTO THIS REGION...AND SOUTHEASTERLY FLOW
IN WARM SECTOR ENHANCES SIZE OF LOW-LEVEL HODOGRAPHS. 

WESTERN FLANK OF  OLD OUTFLOW BOUNDARY ACROSS THE BIRMINGHAM
AREA...SOUTHEASTWARD TO NEAR MONTGOMERY AND DOTHAN WILL PROVIDE
ANOTHER FOCUS. SEVERAL SUPERCELLS HAVE ALREADY DEVELOPED UPSTREAM
OF THIS BOUNDARY...ACROSS SOUTHWEST/CENTRAL ALABAMA...AND TORNADIC
POTENTIAL WILL INCREASE AS THEY ENCOUNTER BOUNDARY NEXT FEW HOURS.
