Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

What happened

The episode as NWS FFC wrote it up.

A broad and increasingly diffluent upper trough was digging into the south central U.S. with broad southwest flow increasing across the southeast U.S. on the back side of a subtropical ridge located across the western Atlantic. This trough eventually set the stage for the historical and catastrophic tornado outbreak that commenced just two days later on the 27th. On this day, however, the atmosphere across Georgia, being unseasonably warm and humid, supported widespread development of pulse-type thunderstorms. Several of these storms became strong to severe and produced large hail and damaging downburst winds. The most significant damage on the east side of Columbus in Muscogee county where a strong downburst blew down several hundred trees and destroyed two trailer homes.

What forecasters said that day

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 Apr 25, 12:52 PM EST, 13 minutes earlier.

.PREV DISCUSSION... /ISSUED 750 AM EDT MON APR 25 2011/

..SIGNIFICANT SEVERE WEATHER EVENT EXPECTED WEDNESDAY...

SYNOPSIS...
A STATIONARY FRONT WAS DRAPED ACROSS THE U.S. FROM N TX TO PA...WITH
A BROAD UPPER TROUGH LOCATED IN THE SOUTH CENTRAL U.S. WIDESPREAD
THUNDERSTORMS...SOME SEVERE AND WITH FLASH FLOODING...CONTINUE ALONG
THE FRONT. THE FRONT AND UPPER TROUGH WILL SHIFT INTO THE EASTERN
U.S. BY WED. SEVERAL ROUNDS OF THUNDERSTORMS ARE EXPECTED THROUGH
MID-WEEK ACROSS NORTH GEORGIA...SOME SEVERE. OTHERWISE...A
WARM...HUMID AIR MASS WILL PREVAIL WITH TEMPERATES AVERAGING 10
DEGREES ABOVE NORMAL.

19

SHORT TERM /TODAY THROUGH WEDNESDAY/...
SEVERE THUNDERSTORMS EXPECTED TUE-WED. VOLATILE SITUATION DEVELOPING
THAT WILL BRING SEVERAL ROUNDS OF THUNDERSTORMS TO THE CWA.
STATIONARY FRONT NOW DRAPED FROM N TX TO PA WILL REMAIN THE FOCUS
FOR WIDESPREAD THUNDERSTORMS...MANY SEVERE AND WITH FLOODING/FLASH
FLOODING. BROAD...HIGHLY DIFFLUENT/NEGATIVELY TILTED UPPER TROUGH
SOUTH CENTRAL U.S. HELPING SUPPORT THE WIDESPREAD SEVERE CONVECTION.
THE TROUGH WILL GRADUALLY SHIFT INTO THE EASTERN U.S. AS UPSTREAM
ENERGY ROTATES AROUND THE PARENT UPPER LOW ACROSS THE WESTERN GREAT
LAKES. THE PRIMARY AFFECT OF THIS ON THE FFC CWA WILL BE
TUE-WED...LIKELY IN THE FORM OF TWO TO POTENTIALLY THREE ROUNDS OF
THUNDERSTORMS. THE FIRST TWO WILL IMPACT MAINLY NW/NC GA...THE THIRD
WILL IMPACT THE ENTIRE CWA. THE FIRST AND LEAST DEFINITE ROUND OF
THUNDERSTORMS WILL COME TUE AFTERNOON AS THE INITIAL SOUTHERN PLAINS
SHORT WAVE LIFTS TOWARD THE OHIO VALLEY AND IS ABSORBED INTO THE
PARENT UPPER LOW. ECMWF/GFS BOTH HINT AT A REMNANT/POSSIBLY
REGENERATING SQUALL LINE REACHING THE NW PART OF THE CWA DURING PEAK
HEATING TUE AFTERNOON WITH HIGH CAPE/INSTABILITY AND WEAK SHEAR. A
FEW OF THESE THUNDERSTORMS COULD BE SEVERE IN THE NW/NC AREA DURING
THE AFTERNOON/EVENING. A BIGGER THREAT FOR SEVERE WEATHER IN NW/NC
GA COMES EARLY WED AS THE NEXT IMPULSE IN THE BROAD UPPER TROUGH
MOVES THROUGH TN/MS/AL.  A SEVERE QLCS IS LIKELY TO BE ONGOING
OVERNIGHT TUE...APPROACHING NW/NC GA BY OR BEFORE 12Z...CONTINUING
INTO MID-MORNING. VERY HIGH SHEAR...WITH 0-3KM BULK SHEAR NEAR 50KTS
AND UNUSUALLY HIGH CAPE FOR EARLY MORNING...ON THE ORDER OF 2000
J/KG...IS PROGGED TO SHIFT INTO NW GA ACCOMPANYING THESE
THUNDERSTORMS. A SEVERE QLCS IS LIKELY...CAPABLE OF SUPPORTING
DAMAGING WINDS AND TORNADOES. THE FINAL UPPER SHORT WAVE ROTATES
INTO THE PARENT LOW WEDNESDAY AFTERNOON WITH A STRONG NEGATIVE TILT.
A STRONG COLD FRONT WILL ACCOMPANY THIS FEATURE. THE DEGREE OF EARLY
MORNING CONVECTIVE DEBRIS CONTAMINATION WILL LARGELY PLAY INTO THE
DEGREE OF SEVERITY OF AFTERNOON CONVECTION. HOWEVER...EASTERN AND
SOUTHERN AREAS WILL LARGELY REMAIN UNAFFECTED BY THE MORNING
ACTIVITY...AND WITH EXTREME SHEAR AND HIGH INSTABILITY IN
PLACE...SUPERCELL THUNDERSTORM DEVELOPMENT APPEARS LIKELY.
FINALLY...THERE WILL ALSO BE CONCERN FOR HEAVY RAINFALL ACROSS NW/NC
GA...AS THESE REPEATED ROUNDS OF THUNDERSTORMS TRACK ACROSS THE SAME
REGION. STREAMS/CREEKS IN THIS REGION ARE HIGH FROM RECENT PREVIOUS
EVENTS. AT THIS POINT...EXCESSIVE RAINFALL IS PROGGED TO REMAIN JUST
NW OF THE CWA...BUT RAINFALL OF 2-3 INCHES NW GA OVER THE 2-DAY
PERIOD WILL AT A MINIMUM RESULT IN SOME RIVER FLOODING. AN ESF WILL
BE ISSUED THIS MORNING TO ADDRESS THIS SITUATION.

BESIDE ALL OF THE DAY2-DAY3 ACTIVITY...IS SURPRISE ONGOING
CONVECTION. MERGING SEA-BREEZES AND A WEAK SHORT WAVE IN INCREASING
SW FLOW ALOFT TRIGGERED LATE AFTERNOON CONVECTION ACROSS S/C GA.
THIS ACTIVITY HAS AMAZINGLY CONTINUED TO HOLD TOGETHER ALL NIGHT
THUS FAR AND HAS MOVED NORTH TO A CSG-MCN LINE. THE GFS ACTUALLY
DEPICTED THIS ACTIVITY VERY WELL...AND SHOWS THAT IT WILL EVENTUALLY
DISSIPATE BETWEEN ATL-CSG BEFORE 12Z. HOWEVER...THE OUTFLOW REMNANTS
AND ADDITIONAL UPSTREAM SHORT WAVE ENERGY IN THE BROAD CENTRAL U.S.
TROUGH ALONG WITH AMPLE AFTERNOON INSTABILITY WILL LIKELY GENERATE
ADDITIONAL PULSE-TYPE THUNDERSTORMS ACROSS N GA THIS
AFTERNOON/EVENING.

FOR TEMPS...NO CHANGE IN AIR MASS AND HENCE NO SIGNIFICANT CHANGES
EXPECTED THROUGH THE SHORT TERM. TEMPERATURES WILL REMAIN WELL ABOVE
NORMAL...ESPECIALLY MINS. A MAV/MET BLEND CONTINUES TO BE THE BEST
WAY TO GO.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
MUCH QUIETER WEATHER EXPECTED THROUGH AT LEAST THE FIRST HALF OF THE
LONG TERM AS THE UPPER TROUGH AXIS SHIFTS EAST OF THE REGION. A
SHORT WAVE RIDGE WILL TRAVERSE THE REGION THROUGH THE WEEKEND WITH
DRY...COOLER NORTHWEST FLOW ALOFT UNTIL SAT. WEAK SFC HIGH PRESSURE
WILL SPREAD FROM THE MID-SOUTH INTO THE SE U.S. ANY THUNDERSTORMS
SHOULD MOVE OUT OF THE CWA BY 12Z THU. BEYOND SAT...THERE IS
CONSIDERABLE DISAGREEMENT BETWEEN THE ECMWF/GFS AS TO WHEN THE NEXT
SYSTEM OF SIGNIFICANCE WILL IMPACT THE CWA. THE GFS BRINGS A SLOWING
WEST-EAST ORIENTED FRONT INTO THE CWA SUN...WHILE THE ECMWF HOLDS
THIS OFF UNTIL THE MIDDLE OF NEXT WEEK. OVERALL...THE GFS APPEARS
MORE REASONABLE AND CONSISTENT WITH THE PROGRESSIVE FLOW OF RECENT
WEEKS. WILL INTRODUCE LOW POPS FOR TSRA SUN FOR NOW...BUT LEAVE THE
REMAINDER OF THE EXTENDED PERIODS DRY. IF THE GFS PATTERN IS
CORRECT...WILL NEED TO BUMP POPS UP CONSIDERABLY FOR SUN.

TEMPERATURES WILL RETURN TO MORE SEASONAL LEVELS THU-FRI...THEN WARM
BACK TO ABOVE NORMAL BY THE WEEKEND. WITH DEWPOINTS DROPPING INTO
THE 40S THU-SAT...NIGHTS WILL BE NOTICEABLY COOLER.

.AVIATION...
18Z UPDATE...
INCREASING MOISTURE/INSTABILITY HAS RESULTED IN SCT SHRA'S ALREADY
DEVELOPING EARLY THIS AFTN...AND SEVERAL WILL LIKELY REACH CB STATUS
BY 18-20Z. PROXIMITY OF SHRA'S TO ATL HAS WARRANTED MENTION OF CB
FROM 18Z THRU THE AFTN. MOIST SOUTHERLY WINDS WILL RESULT IN SCT-BKN
MID CLOUDS THIS AFTN...BUT CAT SHOULD HOLD VFR. ALTHOUGH WINDS WILL
DANCE FROM 190 TO 170 DIRECTION...EXPECT A SSE DIRECTION TO PREVAIL
THIS AFTN AND OVERNIGHT. ADDED A LOW WIND GUST FOR THIS AFTN AS
GRADIENT TIGHTENS IN RESPONSE TO LOW PRESSURE OVER MS VALLEY. EXPECT
MVFR CIGS TO DEVELOP BY 09-10Z TUE...THEN IMPROVE TO VFR BY 15-17Z
TUE. EXPECT SCT TSTMS TUE AFTN...SO ADDED PROB30 19Z-24Z TUE.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.

.DAY ONE...TODAY AND TONIGHT
SCATTERED THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND EVENING.

SCATTERED THUNDERSTORMS ARE EXPECTED MAINLY OVER NORTH GEORGIA ON
TUESDAY. SOME STORMS MAY BE SEVERE. WIDESPREAD THUNDERSTORMS ARE
EXPECTED ACROSS NORTH AND CENTRAL GEORGIA WEDNESDAY INTO EARLY
