AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
230 PM CDT FRI AUG 4 2000

STORMS FIRING IN THE HEAT OF THE AFTERNOON AS ANTICIPATED...BUT
COVERAGE RELATIVELY LIMITED...EXCEPT RIGHT HERE IN THE METRO.
UPSTREAM IMPLULSES LOOKING UNIMPRESSIVE AT THIS POINT...BUT
INDICATIONS ARE THAT THERE COULD BE A LITTLE DEVELOPMENT LATER
TONIGHT AS A VERY WEAK UPPER LEVEL IMPULSE MOVES SE IN THE NWLY
FLOW. MAJORITY OF ACTIVITY WILL BE IN VICINITY OF FRONT...WHICH IS
NORTH/EAST OF OUR AREA...SO THINK POPS WILL BE LIMITED AGAIN TO THE
NE QUAD OVERNIGHT...AND EVEN THERE CHANCES ARE SLIM.

OF COURSE...FIRST PERIOD POPS WILL BE PARTIALLY DETERMINED BY RADAR
TRENDS...WITH A LITTLE CONSIDERATION TO ANYTHING UPSTREAM. BEYOND
THAT...COULD SEE SOME DIURNAL CONVECTION ON SATURDAY...MAINLY IN
E/SE PARTS OF FA...THEN LOOKS MAINLY DRY BEYOND THAT.

FWC MOS TRIES TO LOWER TEMPS ON SUNDAY COMPARED TO SATURDAY. DO NOT
SEE WHY THIS WOULD HAPPEN AS U/L AND SFC RIDGE BUILDS INTO THE AREA
AND WE GO COMPLETELY OUT OF THE STORM TRACK. AVN SEEMS BETTER IN THE
TEMP DEPT...AND IN THE SCENARIO DEPARTMENT OVERALL...SO WILL LEAN IN
THAT DIRECTION...AND GO A FEW DEGREES ABOVE IN PD 4 AS A RESULT.

EXTENDED...DRY AND HOT. SOME SMALL OPPORTUNITIES FOR RAIN LATE IN
THE EXTENDED BUT NOTHING WORTH INCLUDING AT THIS EARLY STAGE.

PRELIM DIGITS... (FIRST PERIOD POPS SHOWN ARE AFTER DIURNAL CONVCTN)
