.DISCUSSION...
/ISSUED 1035 AM CDT FRI JUL 27 2012/
THANKS TO AN EARLY MORNING RAPIDLY EXPANDING STRATOCU
FIELD...TEMPERATURES ARE SEVERAL DEGREES COOLER THAN THIS TIME
YESTERDAY. AS THIS DECK BECOMES MORE CELLULAR IN NATURE WHILE
SLIDING SOUTHEAST...THE CLOUDS ASSOCIATED WITH A PREFRONTAL BOUNDARY
ARE BEGINNING TO MOVE INTO OUR SOUTHERN MIDDLE TENNESSEE COUNTIES.
BOTH WITHIN THE STRATOCU REGION AND NEAR THE BOUNDARY ACROSS
TENNESSEE...LIGHT RETURNS ON THE RADAR HAVE BEEN NOTED...WITH A FEW
CG'S ASSOCIATED WITH ONE CELL IN PARTICULAR ACROSS MIDDLE TENNESSEE.
THE FORECAST QUESTION FOR TODAY WILL CENTER UPON THUNDERSTORM
COVERAGE AND STRENGTH THIS AFTERNOON...WHICH WILL BE LARGELY
INFLUENCED CURRENT CLOUD COVER.

BUFR SOUNDINGS AT MSL AND HSV OFF THE NAM /AND TO SOME EXTENT THE
GFS/ DID INDICATE THIS LOW STRATUS DECK...AND THESE SOUNDINGS
SUGGEST THAT BASES WILL CONTINUE TO LIFT THROUGH THE MORNING HOURS.
HOWEVER...THE APPROACHING MID CLOUD DECK FROM TENNESSEE MAY SOMEWHAT
TEMPER HEATING AND THEREFORE INSTABILITY THIS AFTERNOON. NEVER THE
LESS...SOUNDINGS INDICATE THAT MICROBURSTS WILL BE POSSIBLE TODAY.
GIVEN THAT MUCH OF THE MID/UPPER LEVEL FORCING IS EITHER NORTH OF THE
CWFA ASSOCIATED WITH THE SHORTWAVE...OR SOUTHEAST OF HERE ASSOCIATED
WITH A REMNANT MCS...THE STRONGEST STORMS WILL LIKELY DEVELOP WITHIN
POCKETS OF ENHANCED DAYTIME HEATING.

MUCH OF THE ACTIVITY SHOULD SUBSIDE THIS EVENING WITH BOTH THE LOSS
OF DAYTIME HEATING...AND THE PREFRONTAL TROUGH SINKING SOUTH OF THE
REGION. THE GOING FORECAST FOR THE AFTERNOON IS IN GOOD SHAPE...BUT
MADE SEVERAL TWEAKS TO THE SHORT TERM FORECAST TO BETTER REFLECT
CURRENT WEATHER/SKY COVER. UPDATED ZONES FORTHCOMING SHORTLY.

JLL

.AVIATION...
FOR 18Z TAFS...

THE APPROACHING FRONTAL BOUNDARY WILL BRING SHRA/TSRA TO THE AREA
TODAY...POSSIBLY IMPACTING EITHER TERMINAL THIS AFTERNOON WITH BRIEF
GUSTY WINDS AND REDUCED VIS/CIGS. AFTER THE SHRA/TSRA DISSIPATE THIS
EVENING...PATCHY FOG MAY DEVELOP...AND THIS MAY ALSO IMPACT EITHER
TERMINAL LATE TONIGHT/EARLY SATURDAY MORNING. OUTSIDE OF THE TSRA/BR
WINDOWS...VFR CONDITIONS ARE ANTICIPATED WITH MOSTLY LIGHT SOUTHWEST
WINDS.
