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 Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at May 7, 11:58 AM CDT, 36 minutes earlier.

Area forecast discussion, May 7, 11:58 AM CDT, 36 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1158 AM CDT MON MAY 7 2012

.UPDATE...MORNING COMPLEX IS EVOLVING SIMILAR TO EXPECTED AND HAS NOW
PASSED THAT MORNING LULL PERIOD AND IS SHOWING CONTINUED ORGANIZATION
AS THERE REMAINS A BALANCE BETWEEN THE COLD POOL AND NEW SE
PROPAGATING CONVECTION. THE LEADING EDGE IS NOT MOVING INTO
INCREASING INSTABILITY AND LOOK FOR THIS TO CONTINUE TO BE THE CASE
THROUGH THE AFTERNOON. LOOK FOR A MIX OF STRONG/SVR STORMS AS THE
COMBINATION OF LIFT/INSTABILITY SUPPORT THAT. DMG WIND AND QUARTER
SIZED HAIL LOOK TO BE THE MAIN RISKS WITH THE STRONGER CORES ALONG
THE LINE. THERE IS THE POSSIBILITY OF A SVR TS WATCH BEING ISSUED FOR
THE CENTRAL/NE/E PORTIONS PER MD #724.

AS FOR SPECIFIC FORECAST ELEMENTS TODAY...MAIN ADJ HAVE BEEN TO
HOURLY TEMPS. EARLIER ADJ ARE STILL ON TRACK...BUT LOOK FOR AN UPDATE
TO POPS/WX JUST AFTER NOON TO MATCH RECENT TRENDS. THE MOST LIKELY
CHANCES WOULD BE TO LOWER POPS IN THE NW AND INCREASE VALUES ACROSS
CENTRAL AND EASTERN SECTIONS.

THE NEXT CHALLENGE IS TO FIGURE OUT IF NEW DEVELOPMENT WILL OCCUR
BACK TO OUR W/NW WHERE THE SFC BOUNDARY HAS HUNG UP A BIT. THERE ARE
INDICATIONS THAT NEW DEVELOP MAY OCCUR THERE WHERE BETTER FORCING
WILL EXIST DUE TO THE PROXIMITY OF THE LOW LEVEL SYNOPTIC FEATURES
AND THE COMBINATION OF HIGH INSTABILITY IN THAT AREA. IF THAT
OCCURS...LOOK FOR DEVELOPMENT TO MOVE GENERALLY SE DOWN ALONG THE
LEFT OVER SFC BOUNDARY FROM THE CURRENT COMPLEX. TIMING ON THIS IS
VERY DIFFICULT AND IT APPEARS THAT LATER WOULD BE BETTER FOR OUR
AREA. MORE ON THIS IN THE AFTERNOON PACKAGE. /CME/

&&

.AVIATION...
ALL SITES ARE VFR THIS MORNING...BUT THUNDERSTORMS ARE
MOVING INTO THE DELTA AND THEY WILL BRING BRIEF IFR/MVFR CONDITIONS
TO GWO/GLH THIS MORNING. THUNDERSTORMS WILL CONTINUE TO BE POSSIBLE
THIS AFTERNOON ACROSS THE REMAINING SITES WHICH ONCE AGAIN MAY BRING
TEMPO IFR/MVFR CONDITIONS. WINDS THIS AFTERNOON WILL START OUT
SOUTHERLY BETWEEN 5-10 FOR MOST SITES...BUT WILL BE GUSTY WITH
THUNDERSTORM ACTIVITY. PATCHY AREAS OF FOG/STRATUS ARE POSSIBLE ONCE
AGAIN SUNDAY MORNING...ESPECIALLY FOR MEI/HBG. /15/

&&

.PREV DISCUSSION... /ISSUED 1105 AM CDT MON MAY 7 2012/

UPDATE...QUICK UPDATE HERE TO INCREASE POPS ACROSS THE NW AREAS THIS
MORNING TO CATCH THE S/SE MOVING COMPLEX. ADDITIONALLY...TEMPS WERE
ADJ THIS MORNING TO REPRESENT THE COLD POOL MOVING INTO THE DELTA.
THIS WILL ALSO IMPACT MAX TEMPS THIS AFTERNOON AND HIGHS WERE LOWERED
A BIT. OTHER ADJ WERE TO TAPER POPS/WX WORDING BACK TO MORE MIDDAY
AND AFTERNOON FOR CENTRAL SECTIONS.

AS FOR EXPECTATIONS WITH THIS COMPLEX...IT CURRENTLY IS SUB SVR AND
MAINLY A HEAVY PRECIP PRODUCER RIGHT NOW WITH SOME 25-40MPH WINDS.
THESE MORNING COMPLEXES TYPICALLY WANE THROUGH 9-10AM AND THIS SEEMS
TO BE FOLLOWING THE USUAL EVOLUTION. HOWEVER...IF IT CAN REMAIN
SOMEWHAT ORGANIZED THROUGH 10 AM AND NOT HAVE THE COLD POOL RACE OUT
AHEAD OF THE CONVECTION...THEN AN UPSWING IN INTENSITY WILL LIKELY
OCCUR AS THE LEADING EDGE OF THE SYSTEM COMBINES WITH INCREASING
INSTABILITY AND SFC BASED BUOYANCY. IF THIS OCCURS...THEN SVR STORMS
WILL BE POSSIBLE WITH WIND/HAIL THE MAIN RISK. AT THIS
POINT...CENTRAL AND NE/E SECTIONS OF THE CWA WOULD HAVE THE PRIMARY
RISK DUE TO THE S/SE PROPAGATING COLD POOL INTERACTING WITH THE
INCREASING INSTABILITY. THE NW DELTA LOOKS TO GET STABILIZED THIS
MORNING AND MAY BE PROTECTED UNTIL LATER TONIGHT.

LOOK FOR ANOTHER UPDATE LATER THIS MORNING. A BETTER HANDLE ON HOW
THINGS WILL PLAY OUT FOR THE AFTERNOON SHOULD EXIST AFTER WE SEE HOW
THE COMPLEX AND ASSOCIATED COLD POOL EVOLVES THIS MORNING. /CME/
