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 12, 2:59 PM CDT, 4 hours 32 minutes earlier.

Area forecast discussion, May 12, 2:59 PM CDT, 4 hours 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
259 PM CDT TUE MAY 12 2009

.SHORT TERM...THE FRONT THAT WAS LOCATED NEAR THE COAST THIS MORNING
CONTINUES TO LIFT NWD AND WAS LOCATED NEAR THE I-20 CORRIDOR THIS
AFTERNOON. ALTHOUGH AN UNSTABLE AIR MASS HAS LIFTED IN ITS WAKE WITH
SURFACE DEWPOINTS IN THE UPPER 60S TO LOWER 70S...THE AIR MASS
REMAINS CAPPED ENOUGH TO PREVENT SIGNIFICANT CONVECTION SO FAR OTHER
THAN CELLS RELATED TO SEA BREEZE S OF THE FORECAST AREA. STARTING TO
SEE WEAK CELLS DEVELOP OVER SRN SECTIONS OF THE FA. DEVELOPING
CONVECTION SRN AREAS SHOULD REMAIN BELOW SEVERE LIMTS DUE TO WEAK
AND UNORGANIZED WIND FIELDS. CLUSTER OF SHOWERS AND STORMS MOVING
THIS WAY FROM SRN AR WILL MAINTAIN BEST POPS OVER NWRN ZONES THIS
EVENING. SMALL CHANCE THAT THE CLUSTER WILL INTENSIFY SOME IF IT CAN
INTERSECT BOUNDARY DURING THE EARLY EVENING. OTHERWISE LITTLE IN THE
WAY OF WIND OR SHEAR SUPPORT AND ACTIVITY SHOULD BEGIN TO DECREASE
AROUND SUNSET.

MODELS SHOW DRIER AIR MOVING INTO THE REGION WEDNESDAY WITH THE
BOUNDARY NORTH OF THE FORECAST AREA. THE AIR MASS WILL REMAIN VERY
UNSTABLE BUT LITTLE IN THE WAY OF FORCING OR LOW LEVEL CONVERGENCE
IS INICATED AND FLAT RIDGING ADVERTISED FOR TOMORROW WILL HELP
MAINTAIN CAPPING EFFECT. DECIDED NOT TO SPLIT HAIRS AND FOLLOWED MOS
WITH SCATTERED CONVECTION BY THE AFTERNOON DUE TO THE UNSTABLE AIR
MASS BUT CAPPING MAY WELL PREVENT ACTIVITY TOMORROW. SCATTERED
CONVECTION CONTIUED FOR THURSDAY AFTERNOON. THE NEXT HEALTHY SURFACE
BOUNDARY DROPS INTO AR/NWRN TN WITH 850 MB THETAE VALUES GREATER
THAN 330 OVER THE ARKLAMISS. FLOW REMAINS WEAK BUT MODELS SUGGEST
WEAK FORCING IN THE FORM OF A WEAK PREFRONTAL CONVERGENCE ZONE OR
POSSIBLY A WEAK WAVE ALOFT.

.LONG TERM...FRIDAY THROUGH TUESDAY...FOR FRIDAY AND SATURDAY THE
AREA WILL CONTINUE TO SEE A BIT OF RIDGING ALOFT AS THE UPPER FLOW
BECOMES MORE AMPLIFIED. SOUTHERLY FLOW AT THE SURFACE WILL CONTINUE
TO BRING IN WARM TEMPERATURES AND MOISTURE.  THIS SHOULD ALLOW FOR
DIURNAL CONVECTION TO DEVELOP EACH AFTERNOON AND EVENING...WHICH
SHOULD LEAVE THE OVERNIGHT HOURS FRIDAY NIGHT RATHER QUIET.

BY THE MIDDLE OF THE WEEKEND THE EASTERN CONUS SHOULD SEE AN UPPER
TROUGH MAKE ITS WAY TOWARD THIS REGION. THIS WILL BRING A BOUNDARY
TOWARD THE REGION SATURDAY NIGHT...WHICH SHOULD MOVE INTO THE AREA
ON SUNDAY...BRINGING WITH IT CONVECTION TO KEEP THE ARKLAMISS REGION
WET FOR THE WEEKEND AND INTO MONDAY OF NEXT WEEK.  THE BOUNDARY IS
EXPECTED TO MOVE SLOWLY SOUTH AND LEAVE THE CWFA ON MONDAY AS
SURFACE HIGH PRESSURE BEGINS TO BUILD INTO THE REGION FROM THE
NORTHWEST. THIS WILL BRING DRIER AIR BACK INTO THE ARKLAMISS REGION
TO LEAVE THE AREA DRY FOR A COUPLE DAYS.

OVERALL HAVE REMAINED PRETTY MUCH WITH GUI FOR POPS THROUGH THE
EXTENDED. TEMPERATURES THROUGH THE REMAINDER OF THE WORK WEEK AND
INTO SATURDAY WILL CONTINUE TO BE ABOVE NORMAL WITH MIDDLE 80S
EXPECTED. AS THE BOUNDARY MOVES INTO THE REGION FOR SUNDAY AND
MONDAY...CLOUDS AND CONVECTION WILL KEEP TEMPERATURES A LITTLE
COOLER FOR THE ARKLAMISS REGION.  HOWEVER TEMPERATURES ARE EXPECTED
TO WARM AGAIN BY THE MIDDLE OF NEXT WEEK WITH SURFACE HIGH PRESSURE
RETURNING TO THE ARKLAMISS. /14/

&&

.AVIATION...OCCASIONAL MVFR/VFR CIGS CAN BE EXPECTED AS WE GO
THROUGH THE AFTN INTO EARLY EVNG AS A WEAK WARM FRONT CONTINUES TO
FOCUS LOW CLOUD DEVELOPMENT. ANOTHER TSTM COMPLEX DEVELOPING OVER AR
MAY RIDE ALONG THIS BOUNDARY LATER TODAY BRINGING CHANCES FOR TSTMS
AT MOST TAF SITES. THERE WILL LIKELY BE SOME LIFR CONDITIONS WITH
FOG/STRATUS AFTER 06Z TONIGHT UNTIL ABOUT 15Z WEDNESDAY. THE WEAK
WARM FRONT WILL SUPPORT ADDITIONAL AFTN TSTM ACTIVITY
THURSDAY...PRIMARILY IN CNTRL/ERN MS. /EC/
