Thunderstorms with heavy rain caused some localized flash flooding in portions of West Central Georgia.
The local office's own words before the first event, 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 the first event at May 13, 6:50 PM EST, 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 750 PM EDT SUN MAY 13 2012 .PREV DISCUSSION... /ISSUED 355 PM EDT SUN MAY 13 2012/ SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/... MAIN FORECAST CONCERN WILL CONTINUE TO BE QPF AND POPS ASSOCIATED WITH LOW PRESSURE SYSTEM INFLUENCING THE SOUTHEASTERN CONUS. THE GFS CONTINUES TO HAVE A SLIGHTLY BETTER HANDLE ON THE SYSTEM AND THE ASSOCIATED PRECIPITATION...THEREFORE LEANED TOWARD MAV INITIALIZATION. SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED UPSTREAM OF THE AREA TO THE SOUTHWEST AND RAPID REFRESH INDICATES THAT THIS DEVELOPMENT WILL CONTINUE THIS AFTERNOON AND INCREASE IN COVERAGE FROM THE WEST AFTER ABOUT 21Z. THIS AREA IS ALSO WHERE THE GREATEST PROGGED INSTABILITIES ARE LOCATED. GUIDANCE HAS WESTERN PORTIONS OF THE AREA GETTING NEAR 1000 J/KG THIS AFTERNOON... WHILE SOME UPSTREAM CELLS TO THE SOUTHWEST NEAR THE WARM FRONT HAVE INCLUDED SOME LIGHTNING SO WILL INCLUDE CHANCE TS WITH RAIN SHOWERS. HAVE INCLUDED LIKELY TO CATEGORICAL POPS ACROSS THE ENTIRE FORECAST AREA THROUGH 00Z TONIGHT AND NEAR DEFINITE POPS IN THE NORTHWEST. REGARDING ANY THUNDERSTORM DEVELOPMENT THIS AFTERNOON... WHILE BULK 0-6KM SHEAR REMAINS WEAK AT NEAR 20KTS... LOW LEVEL SHEAR IS MORE IMPRESSIVE WITH 0-1KM SRH NEAR 200 M2/S2 AND 0-3KM SRH APPROX 200-250 M2/S2. STRONGER STORM POTENTIAL WILL NEED TO BE MONITORED IF THE ATM DESTABILIZES FURTHER IN THIS ENVIRONMENT. AS SFC LOW TRACKS NORTHEASTWARD AWAY FROM THE AREA ON MONDAY... THE ASSOCIATED WEAK COLD FRONT WILL PUSH SOUTHEASTWARD ALLOWING FOR CONTINUED PRECIP CHANCES WITH THE HIGHEST POPS IN THE NORTH AND EAST. FOR MONDAY NIGHT... GUIDANCE VARIES SOMEWHAT WITH THE AMPLITUDE OF A SHORTWAVE SWINGING THROUGH THE FORECAST AREA. NAM HAS A STRONGER WAVE THAN THE GFS...SREF... AND ECMWF... HOWEVER THEY AGREE ON HAVING THE MAIN LONGWAVE TROUGH AXIS STILL WEST OF THE AREA. THIS SHOULD KEEP AT LEAST SLIGHT CHANCE POPS FOR THE FORECAST AREA BUT MAY NEED TO BE INCREASED IF THE OTHER MODEL SOLUTIONS START TO AGREE WITH THE NAM. FORECAST CAPE LOOKS TO BE A BIT HIGHER MONDAY SO HAVE KEPT CHANCE OF TS. FOR ADDITIONAL QPF...NAM AND GFS BUFKIT TIME HEIGHTS BOTH HAVE MAINTAINED A SHALLOWER COLUMN OF HIGH RH VALUES ADVECTING INTO THE AREA THROUGH MONDAY. THIS SUGGESTS THAT THE GREATEST PRECIP TOTALS WITH THIS SYSTEM HAVE ALREADY OCCURRED EARLIER SUNDAY MORNING. HPC QPF APPEARS TO HAVE ALSO PULLED DOWN THE TOTALS SOMEWHAT FROM BEFORE... HOWEVER AN ADDITIONAL INCH TO THREE QUARTERS OF AN INCH IS POSSIBLE BY 00Z MONDAY. FOR TEMPS...MAV GUIDANCE SEEMED REASONABLE SO MADE ONLY MINOR TWEAKS. 03 LONG TERM /TUESDAY THROUGH SUNDAY/... HAVE MADE NO CHANGES TO THE LONG TERM. GFS AND ECMWF STILL SHOW A BROAD TROUGH OVER THE SOUTHEAST THROUGH THURSDAY AND THEN A LOW OFF THE COAST OF THE CAROLINAS. THIS COASTAL LOW COULD PUSH PRECIPITATION BACK WEST ACROSS THE CWA DURING THE LAST PART OF THE EXTENDED...HOWEVER CONFIDENCE NOT HIGH ENOUGH AT THIS TIME TO ADD POPS TO THE LAST DAYS. PREVIOUS EXTENDED DISCUSSION IS INCLUDED BELOW. 41 PREVIOUS LONG TERM DISCUSSION... EXTENDED PROGS CONTINUE TO SHOW A BROAD UPPER TROF OVER THE SOUTHEAST U.S. INTO THURSDAY BEFORE UPPER RIDGE BEGINS TO BUILD IN FROM THE WEST THURSDAY NIGHT/FRIDAY. AT THE SURFACE MODELS MAINTAIN WAVY FRONTAL BOUNDARY SOMEWHERE ACROSS CENTRAL GEORGIA INTO TUESDAY NIGHT...BEFORE SHIFTING INTO SOUTH GEORGIA WEDNESDAY. WITH THIS BOUNDARY STILL IN THE VICINITY AND UPPER TROF OVER THE REGION WILL NEED TO HOLD ON TO SLIGHT CHANCE TO CHANCE POPS FOR MUCH OF THE COUNTY WARNING AREA INTO TUESDAY...THEN FOCUS SHIFTING MORE TO EAST SIDE OF THE STATE TUESDAY NIGHT/WEDNESDAY WITH MODELS SHOWING BEST MOISTURE OVER THE CAROLINAS. WILL KEEP FORECAST DRY THURSDAY INTO SATURDAY WITH WEAK RIDGE OVER THE AREA. HOWEVER... WITH BOTH ECMWF AND GFS HINTING AT A COASTAL LOW DEVELOPING ALONG THE MID ATLANTIC/SOUTHEAST COAST OVER THE WEEKEND WILL NEED TO KEEP A CLOSE WATCH ON FUTURE RUNS TO SEE HOW MODELS HANDLE THIS FEATURE. HAVE GONE WITH JUST CLOUDS FOR NOW. 49 HYDROLOGY... MOST OF THE WIDESPREAD RAIN HAS MOVED EAST OF THE CWA WITH SCATTERED SHOWERS AND THUNDERSTORMS BECOMING THE DOMINANT PATTERN. DURING THE LAST 24 HOURS MOST OF NORTH GEORGIA RECEIVED 1 TO 2 INCHES. AMOUNTS ELSEWHERE HAVE BEEN LESS. THERE HAVE BEEN NO FLOODING PROBLEMS THAT WE KNOW OF. 11 && .AVIATION... 00Z UPDATE... LOW PRESSURE CENTER BRINGING SHOWERS AND THUNDERSTORMS TO THE AREA THIS EVENING THROUGH TONIGHT. EXPECTING SHOWERS ACROSS THE ATL AREA WITH ISOLATED THUNDER ACROSS CSG/MCN. PRECIPITATION SHOULD CONTINUE THROUGH TONIGHT SLOWLY ENDING THROUGH MONDAY AFTERNOON/EVENING. WINDS WILL STAY OUT OF THE SE TONIGHT THEN TURN TO THE SW BY 12-14Z MON. WIND SPEEDS WILL STAY IN THE 5-10KT RANGE. VSBYS WILL BE MAINLY VFR EXCEPT IN AND AROUND SHRA/TSRA DEVELOPMENT. CEILINGS WILL STAY MAINLY IN THE MVFR RANGE WITH A BRIEF PERIOD OF IFR CEILINGS BETWEEN 10-14Z. //ATL CONFIDENCE...00Z UPDATE... CONFIDENCE MEDIUM ON ALL ELEMENTS.
