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, 3:53 PM CDT, 0 minutes earlier.

Area forecast discussion, May 7, 3:53 PM CDT, 0 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
353 PM CDT MON MAY 7 2012

.DISCUSSION...CHALLENGING FORECAST FOR TONIGHT AS THE CURRENT STORM
COMPLEX HAS STABILIZED THINGS IN ITS WAKE AND THE ATMS WILL HAVE TO
RECOVER TO SUPPORT ADDITIONAL ACTIVITY LATER ON. CURRENT ACTIVITY
WILL CONTINUE TO PROGRESS SOUTHWARD ACROSS THE CWA. INTENSITY OF
ACTIVITY HAS DIMINISHED SOME AND MOSTLY STRONG WIND GUSTS SEEM TO BE
THE ORDER WITH AVG GUSTS OF 40-50 MPH OCCURRING WITH THE LARGE
COMPOSITE OUTFLOW. WILL LEAVE THE SVR TS WATCH GOING FOR NOW AND
TRIM COUNTIES OFF THE BACK END AS THE THREAT ENDS.

A REGIONAL TAKE ON THE SITUATION SHOWS THE WESTERN PORTION OF THE
BOUNDARY SLOWING AND ACTUALLY STALLING OVER THE ARKLATEX. HERE IS
THE SOURCE OF CONCERN AS MOST OF THE NUMERICAL GUID HAS NEW ACTIVITY
DEVELOPING HERE AND STEADILY PUSHING BACK INTO THE WESTERN PORTION
OF THE AREA LATER...WITH MOST OF THE CWA SEEING ACTIVITY AT SOME
POINT OVERNIGHT. I'M HAVING A HARD TIMING SEEING ALL OF THE AREA
GETTING PRECIP AGAIN DUE TO THE WORKED OVER NATURE OF MOST OF THE
CWA. MODEL DATA DOES SUPPORT LOW LEVEL MOISTURE RECOVERY OVER THE
WEST AND AT THIS TIME...WILL FOLLOW THE GUID POPS IN THAT AREA. MY
AREA OF CONCERN FOR NOT SEEING PRECIP IS ACROSS THE NE/E-CENTRAL
SECTIONS WHERE THE LOW LEVEL RECOVERY WILL BE MOST DIFFICULT.
CONTRADICTING MY THOUGHTS IS THE GUID AS THAT IS THE AREAS THAT HAVE
THE HIGHEST POPS TONIGHT. SO...FOLLOWING MY ANALYSIS...WILL LOWER
POPS OVER THE NE/E-CENTRAL AREAS FOR TONIGHT AND FOLLOW GUID POPS
WEST. LASTLY...WILL NUDGE POPS UPWARD ACROSS THE SOUTH (HWY 84) TO
MATCH WHAT STILL MAY BE LINGERING AT THE START OF THE PERIOD FROM
THE CURRENT ACTIVITY ALONG THE OUTFLOW.

FOR TOMORROW...MANY QUESTION MARKS EXIST AND THIS PERIOD HIGHLY
DEPENDS ON WHAT OCCURS TONIGHT. THE CONSENSUS OF THE MODELS IS FOR
THE MOST ACTIVITY TO OCCUR ACROSS THE CENTRAL PORTION OF THE CWA. I
CAN SEE THAT...BUT WOULD TAKE IT A STEP FURTHER AND COVER THE ENTIRE
CENTRAL/SOUTH HALF. THIS IS LIKELY WHERE RESIDUAL FOCUS CAN BE
ACHIEVED FROM LEFT OVER BOUNDARIES FROM TODAYS/TONIGHTS ACTIVITY.
ALSO THIS IS THE BEST LOCATION FOR INSTABILITY TO RECOVER. THE
ACTUAL SFC SYNOPTIC FRONT WILL ALSO NEAR AND HELP TO PROVIDE BETTER
LOW LEVEL CONVERGENCE. BY TUE NGT/WED...THE MAIN UPPER TROUGH AXIS
WILL SHIFT THROUGH THE AREA ALONG WITH THE SFC FRONT PUSHING
SOUTHWARD. ADDITIONAL PRECIP LOOKS POSSIBLE AND WILL FOCUS THE
BETTER POPS FOR THE SOUTH HALF. POPS WERE TRIMMED BACK ON WED ACROSS
THE NORTH HALF TO ACCOUNT FOR THE COOLER/DRIER AIR MOVING IN.

AS FOR STRONG/SVR STORMS TONIGHT/TUE...TOUGH CALL ON THAT. THERE
LOOKS TO BE SOME SUPPORT WITH OK LAPSE RATES IN PLACE AND THE
POTENTIAL FOR 3000 J/KG OF SBCAPE TO DEVELOP IF THINGS WORK OUT JUST
RIGHT. IF THAT IS THE CASE...THEN THERE WILL BE A SVR RISK. IF
INSTABILITY IS LESS...THEN LIKELY JUST A FEW STRONG STORMS POSSIBLE.
WILL CONTINUE TO MENTION THE STRONG/SVR RISK AT THIS TIME DUE TO
THOSE UNCERTAINTIES.

AS FOR TEMPS...GUID TEMPS FOR HIGHS/LOWS LOOKS SOLID WITH LOWER
READINGS OCCURRING FROM WHAT HAS BEEN SEEN RECENTLY. ACTUALLY...FOR
WED-FRI...80 DEGREES WILL BE A CHALLENGE TO REACH! MY KIND OF TEMPS
FOR EARLY/MID MAY. /CME/

&&

.AVIATION...THE THUNDERSTORMS HAVE ENDED FOR GWO/GLH/JAN THIS
AFTERNOON...BUT ARE CURRENTLY BRINGING MVFR CONDITIONS TO GTR/MEI
ALONG WITH GUSTY WINDS AS AN OUTFLOW BOUNDARY CONTINUES TO TREK
SOUTH/SOUTHEAST. THE THUNDERSTORMS WILL CONTINUE TO DEVELOP ALONG
AND BEHIND THE BOUNDARY THIS AFTERNOON AND POSSIBLY BRING GUSTY
WINDS ALONG WITH MVFR CONDITIONS TO HBG LATER THIS AFTERNOON. THE
WINDS HAVE BECOME MORE NORTHEASTERLY BEHIND THE BOUNDARY...BUT
REMAIN OUT OF THE SOUTH BETWEEN 5-10 FOR HBG. PATCHY AREAS OF
FOG/STRATUS ARE POSSIBLE ONCE AGAIN TUESDAY MORNING...ESPECIALLY FOR
MEI/HBG. /15/
