AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
338 PM EDT MON MAY 20 2013

.SHORT TERM /TONIGHT THROUGH TUESDAY/...
MODELS ALL IN GOOD AGREEMENT THROUGH THE SHORT TERM. THE UPPER LOW
THAT BROUGHT THE PRECIP TO THE REGION OVER THE WEEKEND IS SLOW TO
EXIT BUT IT IS DOING SO. SOME LINGERING CONVECTION SOUTH OF THE FALL
LINE WHERE THE CAP IS THE WEAKEST THIS AFTERNOON SHOULD DISSIPATE
AFTER SUNSET. EXPECT ANOTHER AREA OF LOW CLOUDS TUESDAY MORNING
ALONG WITH SOME LIGHT FOG BUT THIS SHOULD DISSIPATE AFTER SUNSET.
THE UPPER RIDGE CONTINUES TO BUILD INTO THE SOUTHEAST
TUESDAY...BECOMING MORE LIKE OUR SUMMER PATTERN WITH AFTERNOON AND
EVENING CONVECTION. ALL MODELS FORECAST PLENTY OF CAPE WITH LITTLE
CIN OVER THE AREA TUESDAY AFTERNOON WITH THE BEST INSTABILITY OVER
THE MOUNTAINS AND THE EASTERN PARTS OF THE CWA. WILL MAINTAIN SLIGHT
CHANCE/CHANCE POPS ACROSS MUCH OF THE CWA TUESDAY AFTERNOON. A
LITTLE MORE SUNSHINE WILL HELP TEMPS PUSH WELL INTO THE 80S WITH
SOME LOWER 90S ACROSS WEST CENTRAL GA ON TUESDAY.

17

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
NO MAJOR CHANGES MADE TO THE EXTENDED FORECAST. UPPER LEVEL TROUGH
APPROACHING ON WEDNESDAY AND COMBINED WITH ASSOCIATED MOIST AND
INSTABILITY WILL GIVE POTENTIAL FOR NUMEROUS SHOWERS AND SCATTERED
THUNDERSTORMS ACROSS MAINLY N GA AND MAINLY SCATTERED SHOWERS AND
STORMS FOR CENTRAL GA. A WEAK COLD FRONT GETS INTO THE AREA LATE
THURSDAY...POSSIBILITY ASSOCIATED WITH SOME UPPER LEVEL
SUPPORT...WILL GIVE THE CHANCE FOR SHOWERS AND STORMS. BEST
MOISTURE AND UPPER SUPPORT DRIFTING EAST ON FRIDAY ALLOWING FOR
ONLY A SLIGHT CHANCE OF SHOWERS AND STORMS. OVERALL MOISTURE AND
INSTABILITY APPEAR LACKING SATURDAY INTO MONDAY AND WHILE PRECIP
POTENTIAL IS NOT ZERO IT LOOKS TO BE LESS THAN 20 PERCENT AT THIS
TIME. TEMPERATURES RUNNING WITHIN 5 DEGREES OF NORMAL THROUGH THE
PERIOD.
