.DISCUSSION...
/ISSUED 1009 AM CDT TUE MAY 21 2013/
TEMPERATURES ACROSS THE TENNESSEE VALLEY ARE HOVERING AROUND THE
80-DEGREE MARK ALREADY THIS MORNING, THANKS TO MAINLY CLEAR
CONDITIONS IN PLACE ACROSS THE REGION. A CLUSTER OF THUNDERSTORMS IS
CURRENTLY NORTH AND WEST OF THE CWA THIS MORNING, AND WILL CONTINUE
MOVING OFF TO THE NNE. THE SOUTHERN EXTENT OF THIS ACTIVITY WILL
LIKELY CLIP PORTIONS OF NORTHWESTERN ALABAMA THROUGH NOON TODAY. MORE
ISOLATED SHRA/TSRA EXPECTED THIS AFTERNOON ACROSS THE AREA AS THE
CLUSTER RIDES AROUND THE WEAK RIDGE IN PLACE, BUT MUCH OF THE AREA
WILL REMAIN DRY TODAY.

OTHER THAN A FEW TWEAKS TO THE WX/POP GRIDS FOR TODAY, NO CHANGES
WERE NECESSARY TO THE CURRENT FORECAST.

WILL FRESHEN WORDING IN THE ZONES AND RESEND THEM SHORTLY.

.AVIATION...
FOR 18Z TAFS...
SHOWERS/STORMS IN THE VICINITY OF KMSL WILL CONTINUE THRU THIS
EVENING BEFORE MOVING OFF TO THE NE OF THE TERMINAL. THE CURRENT VFR
CONDS AT BOTH TERMINALS WILL DETERIORATE THRU THE PERIOD THOUGH, AS A
COLD FRONT AND SEVERAL WAVES OF SHRA/TSRA OVERSPREAD THE AREA. THE
FIRST OF THESE IS EXPECTED TOMORROW MORNING JUST AFTER DAYBREAK AT
KMSL. CONDITIONS THAT WARRANT ADDITIONAL FUEL WILL BE LIKELY IN THE
HEAVIER TSTORMS, WHICH IS ACCOUNTED FOR IN A TEMPO GROUP LATE IN THE
PERIOD THERE, AND THEN AT KHSV A COUPLE OF HOURS LATER. STORMS WILL
LINGER IN THE VICINITY OF BOTH TERMINALS THRU 22/18Z, WITH ANOTHER
ROUND OF STORMS EXPECTED AFTER THIS TIME.
