A very warm and unstable airmass was in place over the region on the 10th with temperatures reaching into the mid to upper 80s across the region. A very slow moving cold front moved through Texas into Louisiana during the day on the 10th, bringing tornadoes to portions of central Arkansas near Little Rock.

The episode as NWS JAN wrote it up.
A very warm and unstable airmass was in place over the region on the 10th with temperatures reaching into the mid to upper 80s across the region. A very slow moving cold front moved through Texas into Louisiana during the day on the 10th, bringing tornadoes to portions of central Arkansas near Little Rock. Some thunderstorms developed ahead of the approaching squall line, bringing some hail to portions of northeast Louisiana. Without a strong push behind the front, it lingered across locations west of the Mississippi River through most of the evening and overnight hours of the 10th through 11th.
The cold front and squall line finally pushed east early on the 11th. Temperatures across east Mississippi were able to remain warm and conditions remained unstable and supportive of severe weather. A few supercells developed ahead of the cold front. One that tracked through Kemper and Noxubee counties spawned a tornado that caused structural damage in this area. Unfortunately, five injuries and one fatality also occurred in Kemper County near Liberty. Another 4 injuries occurred in Noxubee County as well. Additional damage was noted in Clarke, Jasper and Forrest counties where trees were downed and some damage to structures was reported.
The cold front and post frontal rains finally moved out of the ArkLaMiss by mid afternoon, causing additional damage east to Alabama and Georgia.
In addition to severe weather, the region once again saw plenty of rainfall. On the 10th, locations across the Delta saw 1.5-3.5 inches of rain. The rain was more progressive as it tracked east but 1 to 2 inches was seen.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
503 PM CDT WED APR 10 2013
.DISCUSSION...
...SEVERE WEATHER AND HEAVY RAINFALL EVENT TONIGHT AND THURSDAY...
PER 18Z SHV SOUNDING...INCREASING LIFT AND STRONG DAYTIME HEATING
(SURFACE BASED CAPE ~2000 J/KG) HAVE HELPED TO ERODE THE CAP AND WE
ARE NOW SEEING EVIDENCE OF DEEPER DISORGANIZED CONVECTIVE
PRECIPITATION OVER NORTH CENTRAL INTO NORTHEAST LOUISIANA AND EVEN
SOUTHWEST MS BASED ON LATEST 88D RADAR DATA. DEEP LAYER SHEAR
GENERALLY LESS THAN 35-40 KT IS MARGINAL FOR GETTING SUPERCELLS BUT
EFFECTIVE LOW LEVEL HELICITY IS IN THE 250-300 M2S2 RANGE SO THESE
CELLS WILL BEAR WATCHING. THE MORE INTENSE CONVECTION IS ORGANIZING
ALONG A STRONG COLD FRONT OVER WRN AR AND NW LA IS MARKED BY A 35 TO
45 DEG F THERMAL GRADIENT AND IN ASSOCIATION WITH IMPRESSIVE SPLIT
UPPER LEVEL JET EXIT REGION OVER THE ARKLATEX. STRONG HEIGHT FALLS
AND FRONTAL CONVERGENCE WILL EVENTUALLY HELP TO DEVELOP AN ORGANIZED
LINEAR CONVECTIVE SYSTEM THAT GUIDANCE CONSENSUS SUGGESTS WILL MOVE
INTO NORTHWEST PORTIONS OF THE FORECAST AREA BY LATE EVENING. THE
GREATER CHANCE FOR SEVERE WEATHER INCLUDING DAMAGING STRAIGHT-LINE
WINDS...TORNADOES...AND HAIL WILL OCCUR AT THIS TIME AND PERHAPS
INTO THE EARLY MORNING HOURS. THIS IS WHEN THE DEEP LAYER SHEAR WILL
BE MOST FAVORABLE FOR GETTING BREAKS IN THE CONVECTIVE LINE AND WHEN
LOW LEVEL HELICITY AND INSTABILITY WILL BE GREATEST.
AS THE CONVECTIVE SYSTEM MOVES FARTHER EAST TOWARD THE NATCHEZ TRACE
CORRIDOR...DEEP LAYER SHEAR WILL BECOME MORE UNIDIRECTIONAL AND
INSTABILITY WILL DECREASE SOME AS THE FIRST UPPER LEVEL TROUGH
DEPARTS. THIS WILL RESULT IN A DECREASE IN SEVERE WEATHER
POTENTIAL...BUT AN INCREASE IN HEAVY RAIN AND FLOODING POTENTIAL AS
THE LINE OF STORMS SLOWS DOWN. 850-300 MB VECTORS WILL BE SIMILAR AND
CORFIDI VECTORS LIGHT IN THE 06-12Z TIME FRAME SUGGESTING THAT BACK-
BUILDING AND TRAINING OF STORMS WILL BE POSSIBLE. STRONG UPPER LEVEL
DIVERGENCE ASSOCIATED INITIALLY WITH THE EXIT REGION AND THE ENTRANCE
REGION OF THE UPPER LEVEL JET COMBINED WITH STRONG MOISTURE
CONVERGENCE AND PRECIPITABLE WATER OF 1.8 INCHES WILL PROVIDE THE
INGREDIENTS FOR EFFICIENT HEAVY RAIN-PRODUCING THUNDERSTORMS. SOME OF
THE HIGH-RESOLUTION GUIDANCE SUGGESTS UP TO AROUND SEVEN INCHES OF
RAIN WILL BE POSSIBLE IN A NARROW ZONE FROM LATE TONIGHT THROUGH
THURSDAY MORNING...ESPECIALLY OVER THE NORTHWEST HALF OF THE AREA
AND HAVE EXPANDED/EXTENDED THE FLASH FLOOD WATCH.
THE PRIMARY SHORTWAVE TROUGH WILL SWING ACROSS THE AREA BY THURSDAY
AFTERNOON AND THIS COULD SUPPORT REINTENSIFICATION OF THE SEVERE
WEATHER POTENTIAL OVER EASTERN MISSISSIPPI...ALTHOUGH IT APPEARS THE
GREATER RISK WILL SET UP OVER ALABAMA WHERE GREATER DAYTIME HEATING
AND DESTABILIZATION WILL OCCUR. EXPECT THIS WAVE TO FORCE THE
CONVECTIVE SYSTEM EASTWARD AT A MORE RAPID PACE AND CONVECTION WILL
END BY THURSDAY EVENING WITH DRIER AND COOLER CONDITIONS EXPECTED
THURSDAY NIGHT. /EC/
FRIDAY THROUGH WEDNESDAY...DRY FRIDAY WITH TEMPERATURES TOPPING OUT
JUST BELOW NORMAL IN THE LOWER 70S. NORMAL HIGHS RUN IN THE MID 70S.
THE 00Z MAV GUIDANCE AND GFS ENSEMBLE MEANS CAME IN SEVERAL DEGREES
WARMER THAN LAST NIGHT'S RUN AND LOOK REASONABLE. THE CLOSED UPPER
LOW WILL BE OVER THE GREAT LAKES REGION WITH NEAR ZONAL FLOW ALOFT
OVER OUR REGION. AT THE SURFACE...HIGH PRESSURE WILL BE RIDGING
SOUTHEAST FROM THE PLAINS ACROSS OUR CWA. NEAR FULL INSOLATION...WITH
ONLY A LIGHT NORTH WIND WITH LOW RELATIVE HUMIDITY SHOULD ALLOW
TEMPERATURES TO WARM RAPIDLY FRIDAY MORNING. OUR FLOW ALOFT WILL BACK
TO THE SOUTHWEST FRIDAY NIGHT INTO SATURDAY AHEAD OF A TROUGH OVER
THE DESERT SOUTHWEST. THE GFS AND ECMWF DIFFER WITH THIS FEATURE AS
THE GFS HAS A CLOSED LOW OVER THE BAJA REGION BY SATURDAY MORNING
WHILE THE ECMWF HAS AN OPEN TROUGH. THE ECMWF IS FASTER IN SWINGING
THE TROUGH EAST TO THE SOUTHERN PLAINS BY SUNDAY MORNING WHILE THE
GFS HOLDS THE CLOSED LOW BACK OVER OLD MEXICO. AS THE SURFACE RIDGE
SHIFTS EAST OF OUR AREA SATURDAY NIGHT RETURN FLOW WILL BEGIN
INCREASING MOISTURE TO THE REGION SUNDAY. THIS SHOULD LEAD TO RAIN
DEVELOPING OVER THE SOUTHERN ZONES SUNDAY AFTERNOON. THE ECMWF IS
MORE GENEROUS WITH THE RAIN DUE TO THE CLOSER PROXIMITY OF THE
APPROACHING SHORTWAVE TROUGH BUT THE GFS CATCHES UP SUNDAY NIGHT. BY
MONDAY MORNING THE ECMWF HAS THE AXIS OF THE SHORTWAVE EAST OF OUR
CWA WHILE THE GFS PLACES THE AXIS OVER THE ARKLATEX. BOTH MODELS
MAINTAIN A SOUTHWEST FLOW ALOFT ACROSS OUR REGION WITH SEVERAL
ADDITIONAL EMBEDDED DISTURBANCES THROUGH WEDNESDAY THAT WILL COMBINE
WITH DAYTIME HEATING AND INCREASING MOISTURE TO PROVIDE AT LEAST
DIURNALLY DRIVEN CHANCES OF SHOWERS AND THUNDERSTORMS. BOTH MODELS
ARE SHOWING A SURGE OF UPPER 60 TO LOWER 70 DEW POINTS INTO THE
SOUTHERN PORTIONS OF OUR CWA MONDAY THROUGH WEDNESDAY TO HELP FUEL
THE CONVECTION. WARMER THAN NORMAL TEMPERATURES ARE ALSO EXPECTED
SUNDAY THROUGH WEDNESDAY. HOWEVER...MODEL DIFFERENCES ARE FURTHER
AMPLIFIED BY WEDNESDAY MORNING AS THE GFS HAS A CLOSED LOW TRACKING
ACROSS THE NORTHERN PLAINS WITH NEAR ZONAL ACROSS MUCH OF THE WESTERN
CONUS. THE ECMWF HAS AN AMPLIFIED TROUGH OVER THE ROCKIES. EITHER
SCENARIO WILL STILL LEAD TO DISTURBED WEATHER OVER OUR REGION THROUGH
MID WEEK. /22/
