What forecasters said that day

The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at Jul 10, 2:47 PM EDT, 15 minutes earlier.

Area forecast discussion, Jul 10, 2:47 PM EDT, 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
247 PM EDT WED JUL 10 2013

.PREV DISCUSSION... /ISSUED 737 AM EDT WED JUL 10 2013/

PREV DISCUSSION... /ISSUED 357 AM EDT WED JUL 10 2013/

SHORT TERM /TODAY THROUGH THURSDAY NIGHT/...
SYNOPTIC GUIDANCE CONTINUES IN VERY GOOD AGREEMENT THROUGH THE SHORT
TERM. STRONG UPPER HIGH OVER THE PLAINS AND DESERT SOUTHWEST
CONTINUES TO RIDGE INTO THE SOUTHEAST...UPPER LOW CONTINUES TO MOVE
WEST OVER THE BAHAMAS AND STRAITS OF FLORIDA...AND UPPER TROUGH IN
SOUTHERN CANADA/GREAT LAKES CONTINUES TO DIG SOUTH. SURFACE FRONT
STRETCHED FROM THE GREAT LAKES BACK TOWARD THE MID-MISSISSIPPI
VALLEY THIS MORNING. SHORTWAVE EMBEDDED IN THE WEAKNESS ALOFT
STRETCHED FROM THE GREAT LAKES DOWN TOWARD THE UPPER TENNESSEE
VALLEY ON THE 00Z UA ANALYSES...ESPECIALLY EVIDENT AT 500 AND 700MB.
AS THAT SHORTWAVE PUSHES EAST AND DIGS...THE UPPER HIGH WILL RETREAT
SOMEWHAT. AS THE GREAT LAKES TROUGH CONTINUES TO DIG AND THE ENTIRE
WAVETRAIN INCREASES IN AMPLITUDE...THE FRONT WILL PUSH SOUTH...
ENTERING NORTH GEORGIA THURSDAY MORNING AND PUSHING ACROSS THE STATE
DURING THE DAY...BUT PROGGED TO SLOW DOWN LATE IN THE DAY AND MAKE
LITTLE PROGRESS ANY FARTHER SOUTH INTO THE EXTENDED.

AMPLE MOISTURE /SURFACE DEWPOINTS PROGGED IN THE MID-70S ACROSS SOME
OF THE AREA THIS AFTERNOON/ WILL CONTINUE WITH MODERATE TO HIGH
CAPES IN PLACE. CONVECTION ONGOING AT AFD TIME IS PROGGED BY HIRES
MODELS TO CONTINUE MAINLY ACROSS EASTERN ZONES THROUGH THE
MORNING...MOVING SOUTH AND GRADUALLY DYING OUT DURING THE LATE
MORNING HOURS...BUT AT THE SAME TIME SCATTERED TO WIDESPREAD
CONVECTION DEVELOPS AS A RESULT OF SHORTWAVE FORCING ALOFT AND
CONVECTIVE INSTABILITY. HAVE GONE LIKELY POPS ACROSS MOST OF NORTH
GEORGIA FOR THIS AFTERNOON. KEPT CHANCE POPS IN OVERNIGHT AS AMPLE
MOISTURE AND SURFACE INSTABILITY CONTINUE WITH WEAKNESS ALOFT AND
APPROACHING FRONT. HIRES MODELS DO MOSTLY INDICATE THAT THERE COULD
BE A BREAK AROUND 12Z THURSDAY BUT THAT REMAINS TO BE SEEN. IN ANY
CASE...EXPECT MORE WIDESPREAD CONVECTION TO MOVE IN LATE THURSDAY
MORNING INTO THURSDAY AFTERNOON WITH THE FRONT. THERE IS PROBABLY
ENOUGH SUPPORT TO GO CATEGORICAL BUT STILL A LITTLE UNSURE ON TIMING
OF BEST POPS...SO KEPT THEM LIKELY AT BEST FOR NOW.

ALL THAT SAID...WITH THE ADDITION OF WEAK SHEAR FROM THE UPPER
SYSTEM...LIFT AND SUPPORT FROM THE FRONT...PLUS CONVECTIVE
INSTABILITY...EXPECT THAT NOT ONLY WILL COVERAGE INCREASE ON
THURSDAY BUT INTENSITY AS WELL. CANNOT RULE OUT STRONG TO ISOLATED
SEVERE STORMS WITH DAMAGING WINDS AND POSSIBLY LARGE HAIL. OF
COURSE...WITH THE SATURATED SOILS IT WILL NOT TAKE 50KT WINDS TO GET
TREES TO COME DOWN. THIS POINT CANNOT BE EMPHASIZED ENOUGH...AND
RESIDENTS SHOULD BE PREPARED FOR DOWNED TREES EVEN IN TECHNICALLY
SUB-SEVERE STORMS. THE MAIN THREAT...HOWEVER...THROUGH THE SHORT
TERM IS THE CONTINUED HEAVY RAIN. SEE HYDROLOGY SECTION BELOW.

TEMPS REMAIN AT TO JUST SLIGHTLY BELOW NORMAL. BIAS-CORRECTED BLEND
WORKED YESTERDAY AND SINCE TEMPS ARE CERTAINLY NOT THE MAIN CONCERN
THROUGH THE SHORT TERM...USED THE SAME BLEND FOR THIS FORECAST.

TDP

LONG TERM /FRIDAY THROUGH TUESDAY/...
STALLED FRONTAL BOUNDARY STILL SITUATED ACROSS CENTRAL/SOUTH
PORTIONS OF THE CWFA ON FRIDAY. SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO DEVELOP ALONG AND AHEAD OF THE BOUNDARY...ESPECIALLY
DURING PEAK HEATING. THUNDERSTORMS WILL BE CAPABLE OF PRODUCING
HEAVY RAINFALL THAT COULD LEAD TO LOCALIZED FLOODING OF ALREADY
SATURATED SOILS. MODELS HAVE THE FRONT BECOMING NEARLY DIFFUSE
ACROSS SOUTH CENTRAL GA ON SATURDAY...BUT THE BOUNDARY COULD STILL
PROVIDE SOME FOCUS FOR CONVECTIVE ACTIVITY MAINLY ACROSS THE
SOUTHERN ZONES.

FORECAST FOR THE LATE WEEKEND INTO EARLY NEXT WEEK WILL DEPEND
HEAVILY UPON THE TRACK OF CHANTAL. THE EXACT MOVEMENT OF CHANTAL
WILL BE INFLUENCED BY THE WEAK FRONTAL BOUNDARY AND RIDGING BUILDING
IN ALONG THE SPINE OF THE APPALACHIANS. ALL INTERESTS IN GA SHOULD
MONITOR THE FORECAST FOR T.S. CHANTAL OVER THE WEEKEND. PLEASE REFER
TO NHC FOR THE LATEST TRACK GUIDANCE.

NLISTEMAA

HYDROLOGY...
TWO ISSUES HERE...ONE FOR TODAY AND ANOTHER FOR TOMORROW. FOR
TODAY...PORTIONS OF EAST CENTRAL GEORGIA HAVE REALLY GOTTEN HAMMERED
THE PAST COUPLE OF DAYS. 1- 3- AND 6-HR FLASH FLOOD GUIDANCE
PARTICULARLY LOW IN THESE AREAS. WITH THAT...HAVE OPTED TO ISSUE A
SMALL-SCALE FLASH FLOOD WATCH FOR THESE AREAS...GENERALLY EAST OF A
LINE FROM GAINESVILLE TO WASHINGTON /WILKES COUNTY/. EXPECT A
LARGER-SCALE THREAT FOR TOMORROW AND ALTHOUGH BASIN-AVERAGE QPF FOR
THURSDAY IS LESS THAN AN INCH...THERE WILL BE LOCALLY HIGHER AMOUNTS
AND WITH SUCH SATURATED SOILS IT WILL NOT TAKE MUCH TO PRODUCE
FLOODING. FOR NOW WILL HIGHLIGHT THIS IN THE HWO BUT EXPECT THAT A
FLOOD OR FLASH FLOOD WATCH WILL NEED TO BE ISSUED FOR PORTIONS OF
NORTH GEORGIA EITHER LATER TODAY OR TOMORROW MORNING.

TDP

.AVIATION...
18Z UPDATE...
SHOWERS AND THUNDERSTORMS ALL OVER THE STATE THIS AFTERNOON. THERE
HAS BEEN LITTLE RAIN AT THE TAF SITES BUT THESE SLOW MOVING STORMS
WILL CAUSE SOME ISSUES WHEN THEY DO REACH AN AIRFIELD. WINDS ARE
MAINLY OUT OF T5HE WEST BUT WITH CONVECTIVE OUTFLOWS WINDS HAVE
BEEN TURNING EAST TO SE. WIND SPEEDS ARE STILL IN THE 5-10KT RANGE
WITH SOME GUST IN AND AROUND CONVECTIVE DEVELOPMENT. CEILINGS VFR
AND SHOULD STAY THERE THROUGH 08Z-10Z WILL SE SOME MVFR CEILINGS
NEAR SUNRISE WITH CEILINGS LIFTING TO VFR BY 15-16Z THU.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTH AND CENTRAL
GEORGIA.

.DAY ONE...THIS AFTERNOON AND TONIGHT...

...FLASH FLOOD WATCH IN EFFECT FOR PARTS OF EAST CENTRAL GEORGIA...

AMPLE MOISTURE AND DAYTIME HEATING WILL RESULT IN SCATTERED SHOWERS
AND THUNDERSTORMS ACROSS THE STATE THIS AFTERNOON AND EVENING. THE
GROUND IS SATURATED AND ADDITIONAL HEAVY RAIN COULD LEAD TO FLOODING
OR FLASH FLOODING. RESIDENTS ARE URGED NOT TO LET THEIR GUARD DOWN
DURING THIS PROLONGED CONVECTIVE LOCALLY HEAVY RAINFALL PERIOD.

WEATHER HAZARDS EXPECTED...

PERIODS OF MODERATE TO LOCALLY HEAVY RAINFALL THIS AFTERNOON AND
EVENING MAY LEAD TO ADDITIONAL FLASH FLOODING AND RIVER
FLOODING...ESPECIALLY ACROSS EAST CENTRAL GEORGIA WHERE HEAVY
RAINS HAVE FALLEN FOR THE LAST FEW DAYS. RAINFALL AMOUNTS
AVERAGING AROUND HALF AN INCH CAN BE EXPECTED ACROSS THE
AREA...WITH LOCALLY HIGHER AMOUNTS POSSIBLE. WHILE THIS AMOUNT OF
RAIN IS NOT PARTICULARLY HIGH... SOILS ARE EXTREMELY SATURATED AND
RIVER LEVELS ARE HIGH...THUS IT WILL NOT TAKE MUCH TO PRODUCE
ADDITIONAL FLOODING.

THUNDERSTORMS WILL PRODUCE OCCASIONAL LIGHTNING... WIND GUSTS TO 45
MPH AND POSSIBLY SOME SMALL HAIL. WITH SATURATED SOILS...IT WILL NOT
TAKE MUCH WIND TO DOWN TREES.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY...

ALTHOUGH THE RAINFALL THROUGH THE WEEK AND INTO THIS WEEKEND WILL
NOT BE AS PROLONGED OR WIDESPREAD AS WHAT WE SAW LAST WEEK...THERE
WILL STILL BE PERIODS OF MODERATE TO HEAVY RAINFALL IN SHOWERS AND
THUNDERSTORMS. THIS IS ESPECIALLY THE CASE THURSDAY AND FRIDAY AS
A FRONT MOVES INTO THE STATE. NORTH GEORGIA WILL AGAIN HAVE THE
BEST CHANCES FOR ADDITIONAL RAINFALL AND THERE IS SOME CONCERN
THAT ACCUMULATING HIGH RAINFALL TOTALS MAY LEAD TO MORE
SIGNIFICANT FLOODING ACROSS THE AREA. PERSONS PLANNING OUTDOOR
ACTIVITIES FOR THE NEXT SEVERAL DAYS SHOULD MONITOR THE LATEST
FORECASTS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT REQUESTED BUT SPOTTERS ARE ENCOURAGED
TO SUBMIT REPORTS OF SEVERE WEATHER THROUGH THE WEB BY GOING TO
WEATHER.GOV/ATLANTA.
