.PREV DISCUSSION... /ISSUED 356 PM EDT THU JUN 16 2011/

SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
A DEEP LAYER OF DRIER AIR SPREADING IN OVER NORTH GA THIS AFTERNOON...AS
NOTED ON LATEST SATELLITE WATER VAPOR IMAGERY...HAS GREATLY HINDERED
ANY CONVECTIVE THREAT THERE THIS AFTERNOON...AND THIS TREND IS EXPECTED
TO CONTINUE THROUGH THE EVENING. A WEAK SURFACE TROUGH PARKED ACROSS
CENTRAL GA...NEAR A COLUMBUS TO DUBLIN LINE... HAS PROVIDED THE
FOCUS FOR ISOLATED THUNDERSTORMS THIS AFTERNOON... AND THIS THREAT
WILL LIKELY CONTINUE INTO MID EVENING...ALTHOUGH SHOULD BE DIMINISHING
AS DRIER AIR SPREADS IN FROM THE NORTH DURING THE EVENING. EXPECT
AN ISOLATED TO LOW SCATTERED THREAT OF AFTERNOON AND EVENING THUNDERSTORMS
FRIDAY AND SATURDAY FOR MOST AREAS AS A SERIES OF UPPER DISTURBANCES
TRAVERSE THE STATE. WEAK SHEAR VALUES AND MODEST INSTABILITY (1500-2000
CAPE, -5 TO -7 LI'S) SUGGESTS PULSE THUNDERSTORMS THAT GENERALLY
STAY BELOW SEVERE LIMITS... ALTHOUGH SMALL HAIL AND WIND GUSTS TO
45 MPH WILL BE POSSIBLE WITH THE STRONGER STORMS. AS FOR TEMPS...STAYED
CLOSER TO THE COOLER MAV LOWS AND WARMER GUIDANCE HIGHS THROUGH
THE SHORT TERM.

LONG TERM /SUNDAY THROUGH THURSDAY/...
UPPER RIDGE BUILDS BACK IN OVER THE DEEP SOUTH BY SUNDAY...AND
PERSISTS THROUGH THURSDAY... AND THEREFORE GREATLY LIMITING CONVECTION
THROUGH THE LONG TERM. WILL CONTINUE A SLIGHT CHANCE POP MAINLY IN
THE MOUNTAINS WHERE BEST LIFT IS EXPECTED. OTHERWISE... WARM TEMPS
CONTINUE WITH HIGHS POSSIBLY APPROACHING THE CENTURY MARK ACROSS
PORTIONS OF CENTRAL GEORGIA BY MONDAY AND TUESDAY AS THE UPPER
RIDGE SETTLES OVER THE STATE. WILL HAVE TO WATCH FOR RECORD HIGHS
ON THESE DAYS.

&&

.AVIATION...
00Z UPDATE...
CONVECTION HAS DIED DOWN FOR THE EVENING NEAR THE TAF SITES. CU
BEGINNING TO CLEAR OUT AS WELL. NORTHWEST WINDS WILL SUBSIDE
OVERNIGHT...BELOW 5KT AT ATL AND NEARLY CALM ELSEWHERE. SOME
GUIDANCE STILL INDICATING A SHIFT TO NORTHEASTERLY WINDS...BUT
MOST GUIDANCE REMAINING ON THE WEST SIDE. WILL PROBABLY ALSO SEE
SOME MVFR FOG AT THE TYPICAL LOCATIONS. EXPECT SCATTERED AFTERNOON
CONVECTION ON FRIDAY...SO HAVE KEPT TREND OF PROB30 AND EXPANDED
IT TO OTHER TAF SITES.

//ATL CONFIDENCE...00Z UPDATE...
MEDIUM ON WIND DIRECTION...HIGH ON WIND SPEED.
MEDIUM ON TIMING OF CONVECTION FRIDAY AFTERNOON.
HIGH ON ALL OTHER ELEMENTS.
