Severe Thunderstorm Warning 228, NWS Nashville, TN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
140 PM CDT SAT AUG 6 2005

.DISCUSSION...
CONVECTION QUICKLY DEVELOPING OVER THE AREA EARLY THIS AFTERNOON. WE
EXPECT TO BE BUSY THROUGH THE REST OF THE DAY MONITORING STORMS AND
POSSIBLY ISSUING A FEW WARNINGS FOR ISOLATED SEVERE CELLS. MAIN
POTENTIAL WILL BE DOWNBURST WINDS AS WE SAW YESTERDAY. LOCALIZED
HEAVY RAIN MAY ALSO OCCUR WITH RELATIVELY SLOW MOVEMENT OF STORMS.
MAJORITY OF STORMS SHOULD DIMINISH LATER THIS EVENING WITH LOSS OF
HEATING.

A LOW PRESSURE SYSTEM WAS LOCATED ACROSS AL/FL AREA AND A
POORLY DEFINED...DISSIPATING COLD FRONT REMAINED JUST TO OUR NORTH.
THE FRONT WILL CONTINUE TO DISSIPATE OVER THE NEXT COUPLE OF DAYS AS
THE LOW PRESSURE DRIFTS NORTHWARD. THE ATMOSPHERE WILL BECOME MORE
MOIST IN MID LEVELS THAN IT HAS BEEN...RESULTING IN MORE CLOUDINESS
AND SLIGHTLY HIGHER RAIN CHANCES...BUT A LITTLE LESS SEVERE
POTENTIAL. THUNDERSTORMS WILL BE POSSIBLE ANY TIME THROUGH THE NEXT
FEW DAYS...BUT PRIMARILY HEAT DRIVEN WITH GREATEST COVERAGE IN THE
AFTERNOON AND EARLY EVENING. HIGH TEMPERATURES COULD BE HELD BELOW 90
IN MANY AREAS SUNDAY THROUGH TUESDAY WITH POTENTIAL FOR INCREASED
CLOUDS AND SHOWERS/STORMS.

APPEARS THAT THROUGH AND DEEP MOISTURE WILL WEAKEN AND LIFT AWAY
FROM THE AREA MIDWEEK AS UPPER RIDGE BUILDS OVERHEAD.
TEMPERATURES WILL PUSH INTO THE LOW TO MID 90S AGAIN LATE WEEK WITH
MS/PC SKIES. NOT SURE THERE WILL BE STORMS EVERY DAY LATE WEEK...BUT
THIS TIME OF YEAR IT IS PRETTY SAFE TO FORECAST ISOLATED CONVECTION.
