THUNDERSTORM COMPLEX MOVING SOUTH OVER CENTRAL GEORGIA IS PUSHING
OUTFLOW TOWARDS EAST CENTRAL ALABAMA WITH NEW THUNDERSTORM
DEVELOPMENT ON THE LEADING EDGE. THERE IS STILL ENOUGH INSTABILITY
OVER PARTS OF EAST CENTRAL ALABAMA TO SUSTAIN A FEW STRONG STORMS
AND POSSIBLY AN ISOLATED SEVERE. WILL ADJUST POPS TO REFLECT
LATEST RADAR TRENDS. ELSEWHERE IT LOOKS VERY QUIET WITH NOTICEABLY
DRIER AIR MOVING INTO THE NORTHERN HALF OF ALABAMA. DEWPOINTS FROM
TCL TO GAD ARE IN THE MID 40S TO MID 50S. TEMPERATURES WILL NEED
TO BE LOWERED A FEW DEGREES IN THESE AREAS AND A FEW UPPER 50S ARE
NOT OUT OF THE QUESTION NORTH OF INTERSTATE 59.

&&

.AVIATION...00Z TAF DISCUSSION.
MOST OF THE STORMS NEAR THE SOUTHERN TAF SITES ARE BEGINNING TO WIND
DOWN FOR NOW.  STILL KEEPING VCTS IN AT TOI AS ADDITIONAL WEAKER
STORMS HAVE DEVELOPED TO THEIR NORTH AND ARE SLOWLY MOVING SOUTH.
THE WINDS WHICH HAVE LARGELY BEEN FROM THE NORTH WILL BEGIN TO SHIFT
OUT OF THE EAST AS THE BACKDOOR BOUNDARY SLIDES FURTHER WEST.  FOR
THE MOST PART SHOULD REMAIN UNDER VFR CONDITIONS WITH THE EXCEPTION
OF SOME HAZY SPOTS SOUTH AT MGM...EET...TOI WHERE MVFR VISIBILITIES
