.PREV DISCUSSION...
AS EXPECTED...BROKEN LINE OF CONVECTION HAS DEVELOPED ALONG A
PREFRONTAL TROF/OUTFLOW BOUNDARY STRETCHING ACROSS NRN MS INTO WRN
KY. DEWPOINTS MAX OUT IN THE UPPER 60S ALONG THIS FEATURE...FALLING
OFF INTO THE LOWER 60S AHEAD OF IT...AND THE UPPER 50S BEHIND IT. SO
FAR RADAR SHOWS A FEW STRONG CELLS BUT NOTHING APPEARS SEVERE YET.
MAIN COLD FRONT IS STILL WELL BEHIND THIS FEATURE ACROSS SRN CENTRAL
MO AND NERN AR. CLOSER TO HOME...A SEPARATE WEAK UPPER LEVEL FEATURE
HAS CAUSED SOME TOWERING CU TO POP ALONG A COLUMBUS MS-LYNCHBURG TN
LINE...BUT SO FAR ONLY A SPRINKLE OR TWO IS ACTUALLY REACHING THE
GROUND.

SEVERE POTENTIAL...HOWEVER SLIM IT WAS ANYWAY...APPEARS TO BE
DIMINISHING. 12Z OHX/BMX RAOBS SHOW PLENTY OF INSTABILITY...BUT
THAT FALLS OFF RAPIDLY AS BLYR MOISTURE IS MIXED OUT BY MIDMORNING
SUNSHINE. AREA WILL LIKELY STABILIZE FURTHER WITH THE PREFRONTAL
ACTIVITY...AND WHILE THERE IS A BREAK IN THE CLOUDS BEHIND
IT...THERE DOESNT APPEAR TO BE ENOUGH LLVL MOISTURE FOR INSTABILITY
TO REBOUND SIGNIFICANTLY. MAY STILL BE ABLE TO SQUEEZE OUT ONE OR
TWO STRONG TO MARGINALLY SVR STORMS THOUGH AS PREFRONTAL STORMS MOVE
INTO MORE UNSTABLE AIR.

GOOD NEWS IS THAT RAIN FOR AT LEAST PART OF THE AREA IS APPEARING
MORE LIKELY. HAVE NOT SEEN ANY MEASURABLE RAINFALL AT HSV FOR THE
MONTH OF MAY (AND JUST 0.01 AT MSL) AND THAT IS LIKELY TO CHANGE.
WILL PROBABLY NEED TO UPDATE BY 10AM TO REVISE POPS...AND A SECOND
LOOK AT TEMPS WILL BE NEEDED AS THE TROUGH MOVES THROUGH.
