The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Atlanta, GA wrote its last area forecast discussion before this special weather statement went out at Aug 4, 1:11 PM EDT, 2 hours 6 minutes earlier.
Area forecast discussion, Aug 4, 1:11 PM EDT, 2 hours 6 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PEACHTREE CITY GA 111 PM EDT THU AUG 4 2011 .PREV DISCUSSION... /ISSUED 1136 AM EDT THU AUG 4 2011/ UPDATE... NEEDED TO LOWER THE EXPECTED HIGH TEMPS TODAY OVER NORTHWEST GA A FEW DEGREES INCLUDING THE ATL METRO AREA. PREVIOUS SHOWERS AND A FEW THUNDERSTORMS THIS MORNING AND THE EXTENDED CLOUD COVER ARE CAUSING THE TEMPERATURES TO WARM MORE SLOWLY. HAVE DROPPED THE HEAT ADVISORY IN THIS AREA ACCORDINGLY WITH HEAT INDICES EXPECTED TO BE AROUND 100. STILL A VERY HUMID SITUATION. MADE SOME POP ADJUSTMENTS AS WELL BASED ON THE CURRENT RADAR TRENDS AND THE HRRR MODEL RUN. HAVE SHIFTED THE LIKELY TSTMS POPS TO NORTHWEST AND WEST CENTRAL GA DUE TO THE LINGERING MCS IN AL. CHANCE POPS WILL DOMINATE THE REMAINDER OF THE CWA. 16 SHORT TERM /TODAY THROUGH SATURDAY/... DEALING WITH DECAYING MCS THIS MORNING SO WILL HAVE TO KEEP THIS RELATIVELY SHORT. AFTER INITIAL MCS MOVES THROUGH PORTIONS OF NORTH GEORGIA THIS MORNING...FORECAST BECOMES MUCH MORE OF A CHALLENGE BASED ON ITS EFFECTS FOR THE REST OF TODAY. THE FIRST ISSUE WILL BE POPS WHICH LOOK INCREASINGLY LIKE WILL BE CONFINED TO AREAS ALONG AND ESPECIALLY SOUTH OF INTERSTATE 20. IN THE POST MCS ENVIRONMENT...STILL COULD SEE SOME SHORTWAVE ENERGY ALLOWING FOR REDEVELOPMENT DURING THE AFTERNOON...MUCH LIKE WHAT HUNTSVILLE SAW IN THE WAKE OF THEIR MCS TONIGHT. STILL EXPECT COVERAGE TO BE LESS IN THESE AREAS AND WILL KEEP POPS IN THE LOW END CHANCE RANGE. OTHER COMPLICATING FACTOR OF MCS IS THE FACT THAT IT IS LIKELY TO LEAVE A COLD POOL IN ITS WAKE. WHILE THE TERM COLD MAY BE PUSHING IT THIS TIME OF YEAR...IT WONT TAKE MUCH TO CURB TEMPS ENOUGH THAT CURRENT HEAT ADVISORY WOULD BE IN JEOPARDY. THINKING AT THIS TIME IS THAT INCREASE IN MOISTURE FROM STORMS MAY HELP OFFSET ANY COLD POOL EFFECTS AND WILL KEEP ADVISORY GOING FOR NOW. TROUGH STALLS OVER CENTRAL GEORGIA WITH HIGHEST POPS REMAINING THERE FOR FRIDAY. THERE IS A LATE ARRIVING SHORTWAVE WHICH COULD BRING ENHANCED ACTIVITY TO THE NORTHWEST CORNER AND WILL ADVERTISE HIGHER POPS THERE AS WELL. LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... COMBINATION OF ADEQUATE MOISTURE...NUMEROUS SHORTWAVES TRAVERSING THE AREA AND SURFACE TROUGH WILL LEAD TO ENHANCED RAIN CHANCES THROUGH THE WEEKEND. 23 && .AVIATION... 18Z UPDATE... GENERALLY VFR CONDITIONS EXPECTED THIS AFTERNOON INTO THE EVENING. SCATTERED THUNDERSTORMS EXPECTED TO DEVELOP ACROSS THE AREA COULD AFFECT ANY TAF SITE. SURFACE WINDS GENERALLY W AROUND 10 KTS OR LESS. PATCHY MVFR VSBYS POSSIBLE LATE TONIGHT. //ATL CONFIDENCE...18Z UPDATE... HIGH CONFIDENCE FOR VFR CONDITIONS AND WINDS INTO THE EVENING.
