CLOSER TO HOME...LATEST OBS SHOWING TEMPERATURES IN THE MID 80S TO NR 90...AND DEWPTS IN THE UPR 60S/LWR 70S. CONDITIONS THROUGH EARLY EVENING WILL BE VIRTUALLY A CARBON COPY OF THE PAST SEVERAL DAYS. SUSTAINED DEEPER MOISTURE AND HIGH CONDITIONAL INSTABILITY WILL PROVIDE ANOTHER ROUND OF DIURNALLY DRIVEN CONVECTION DURING PEAK HEATING. THE INCREASINGLY DIFFUSE SFC FRONT WILL ALSO DRIFT INTO THE AREA LATE TODAY...PROVIDING AN ADDED FOCUS FOR DEVELOPMENT. WITH THIS IN MIND...OVERALL PCPN COVERAGE MAY BE A TAD HIGHER THAN IN RECENT DAYS...AND WILL THUS MAINTAIN THE CURRENT 40% CHANCE.

THE FRONT WILL BECOME DIFFUSE AS IT MOVES INTO THE NORTHERN ALABAMA AREA...WITH ANY ASSOCIATED SFC CONVERGENCE BECOMING WEAK. HOWEVER...POOLING OF LOW LEVEL MOISTURE AND SUFFICIENT DAYTIME HEATING WILL ALLOW FOR SCATTERED CONVECTION TODAY AND SATURDAY.

FOR SUNDAY...GFS ADVERTISING A LITTLE MORE RESIDUAL MOISTURE IN THE WAKE OF THE FRONT...AND RELATIVELY STRONG SHORT WAVE MOVING THROUGH THE AREA DURING DAYTIME HEATING MAXIMUM. THIS WILL LEAD TO DEVELOPMENT OF SCATTERED STORMS AGAIN ON SUNDAY AFTERNOON...SO INCREASED POPS A LITTLE ESPECIALLY IN SOUTHERN AREAS ON SUNDAY.

MOISTURE RETURN INTO THE REGION AROUND THE WESTERN AND NORTHERN FLANK OF A GULF HIGH PRESSURE SYSTEM...COUPLED WITH YET ANOTHER IN A SERIES OF POTENTIAL FRONTAL PASSAGES WILL GENERATE SOME SHOWER/TSRA ACTIVITY FOR THE MID SOUTH AGAIN THURSDAY THROUGH FRIDAY...AND PERHAPS LASTING INTO THE WEEKEND.
