What forecasters said that day

The local office's own words before this river flood 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 river flood warning went out at Dec 29, 9:35 AM EST, 2 hours 54 minutes earlier.

Area forecast discussion, Dec 29, 9:35 AM EST, 2 hours 54 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
935 AM EST TUE DEC 29 2015

.UPDATE...
NO MAJOR CHANGES TO THE FORECAST NEEDED AT THIS TIME. HAVE ONLY
MADE SOME MINOR TWEAKS TO THE SKY COVER GRIDS FOR NOW.

A LULL IN THE PRECIP IS EXPECTED TODAY. HOWEVER...WIDESPREAD
SHOWERS AND A FEW THUNDERSTORMS WILL REDEVELOP ACROSS MUCH OF
NORTH AND CENTRAL GEORGIA TONIGHT. WILL MAKE NO CHANGES TO THE
FLOOD WATCH.

&&

.PREV DISCUSSION... /ISSUED 619 AM EST TUE DEC 29 2015/

UPDATE...
UPDATED FOR 12Z AVIATION DISCUSSION.

PREV DISCUSSION... /ISSUED 212 AM EST TUE DEC 29 2015/

SHORT TERM /TODAY THROUGH WEDNESDAY/...
AREA OF SHOWERS CONTINUING TO PUSH EAST BUT HAS SHOWN A SIGN OF
SLOWING DOWN AND LIFTING NORTHEAST. THE DEEPEST MOISTURE IS
EXPECTED TO STALL IN A SOUTHWEST/NORTHEAST ORIENTATION ACROSS
CENTRAL/NORTHEAST GA...ALTHOUGH IT IS EXPECTED TO DIMINISH
SOMEWHAT. HOWEVER WILL NEED TO KEEP LOW CHANCE POPS GOING FOR
TODAY ACROSS CENTRAL AND PARTS OF NORTHEAST GA THROUGH THE DAY. AT
THIS TIME DO NOT EXPECT MUCH IN THE WAY OF QPF AND THIS WILL
CONTINUE INTO THE EVENING...GIVING US A BRIEF RESPITE FROM THE
HEAVY RAIN. HOWEVER THE SECOND WAVE OF SHOWERS/ISOLATED TSTORMS
WILL BEGIN DEVELOPING ACROSS WEST GA AFTER MIDNIGHT
TONIGHT...SPREADING ACROSS MOST OF THE CWA WEDNESDAY AND EXITING
LATE WEDNESDAY NIGHT/THURSDAY. THE HEAVIEST PRECIP STILL EXPECTED
OVER NORTH GA WEDNESDAY INTO EARLY WEDNESDAY NIGHT WITH ANOTHER
1-2 INCHES POSSIBLE. THIS WILL KEEP RIVERS IN FLOOD AND ALSO CAUSE
NEW FLOODING. FOR THAT REASON THE FLOOD WATCH WILL REMAIN IN
EFFECT AS IS THROUGH 12Z THURSDAY. THERE WILL BE SOME CAPE
ASSOCIATED WITH THE COLD FRONT THAT WILL BE CROSS THE CWA
WEDNESDAY/WEDNESDAY NIGHT AS WELL AS 50 TO 60 KTS OF SHEAR ACROSS
NORTH GA. THIS COULD BE ENOUGH TO PRODUCE ISOLATED SEVERE TSTORMS
WEDNESDAY AFTERNOON/EVENING AND WILL INCLUDE THIS IN THE HWO.

17

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
THE GFS/ECMWF ARE IN PRETTY GOOD AGREEMENT FOR THE LONG TERM. THE
UPPER FLOW REMAINS WEST SOUTHWEST WITH A SECONDARY DISTURBANCE
MOVING ALONG THE GULF COAST FRIDAY. MODELS DIFFER IN THE NORTHWARD
EXTENT OF THE MOISTURE ON FRIDAY WITH THE GFS THE FURTHEST NORTH.
WILL CONTINUE WITH CONSISTENCY AND LEAN TOWARD THE ECMWF SOLUTION
WHICH BRINGS A CHANCE OF SHOWERS TO PARTS OF CENTRAL GA. THE CWA
DRIES OUT FOR THE WEEKEND AS CANADIAN HIGH PRESSURE BUILDS INTO
THE CWA. THIS WILL ALSO BRING OUR TEMPS NEAR NORMAL...SOMETHING WE
HAVENT SEEN IN A WHILE. THE MORE SEASONAL WEATHER WILL LAST INTO
EARLY NEXT WEEK.

17

AVIATION...
12Z UPDATE...
MIX OF VFR/MVFR CIGS THIS MORNING SHOULD BECOMING MOSTLY MVFR WITH
INITIAL LIFTING...THEN RISE TO VFR BY 18Z AND REMAIN VFR INTO THIS
EVENING. AS THE NEXT SYSTEM APPROACHES CIGS WILL LOWER TO
MVFR...THEN TO IFR LATE TONIGHT. DRY FORECAST UNTIL LATE THIS
EVENING AND TONIGHT WITH SHOWERS DEVELOPING ACROSS THE FORECAST
AREA. WINDS WILL BE LIGHT SOUTHWEST THROUGH TODAY...BECOMING LIGHT
SOUTHEAST LATE TONIGHT.

//ATL CONFIDENCE...12Z UPDATE...
MEDIUM ON CIGS.
HIGH ON REMAINING ELEMENTS.
