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 Aug 17, 10:15 AM CDT, 4 hours 51 minutes earlier.

Area forecast discussion, Aug 17, 10:15 AM CDT, 4 hours 51 minutes before

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE JACKSON MS
1015 AM CDT SUN AUG 17 2014

.UPDATE...MINOR ADJUSTMENTS TO POPS AND TEMPS THROUGH TONIGHT.
PREVIOUS FORECAST FOR THE SHORT TERM PERIOD MOSTLY ON TRACK. /BB/

&&

.DISCUSSION...SOUTHERN EXTENT OF INTENSE AND COMPACT UPPER LEVEL
SHORT WAVE IS CLIPPING OUR FAR NORTHERN ZONES THIS
MORNING...PROMPTING ENOUGH LIFT AND MOISTURE ADVECTION TO FUEL A
SOLID BAND OF THUNDERSTORMS STRETCHING FROM THE ARKLAMISS DELTA
NORTHEAST THROUGH PORTIONS OF THE MIDSOUTH AND TN VALLEY. THIS
SLOW-MOVING CONVECTION POSES SOME HEAVY RAIN THREAT...BUT THE BULK
OF THE ACTIVITY SHOULD REMAIN NORTH OF THE CONFINES OF THE CWA.
HOWEVER...EXPECT OUTFLOW RELATED TO THIS ACTIVITY TO SNEAK MORE
FIRMLY INTO NORTHERN ZONES AS THE DAY PROGRESSES AND HELP TO FUEL
ISOLATED TO SCATTERED ACTIVITY INTO THE AFTERNOON HOURS. FURTHER
SOUTH...AMPLE DEEP MOISTURE ADVECTION THROUGH THE PINE BELT COULD
GET SOME ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS GOING EARLY
NEAR HBG. OTHERWISE...ANTICIPATE A MAJORITY OF THE SCATTERED SHOWERS
AND STORMS IN THE SOUTH TO WAIT UNTIL THE AFTERNOON TO FIRE UP. THAT
LEAVES THE PREVIOUS ASSESSMENT OF ONLY ISOLATED ACTIVITY AFFECTING
CENTRAL ZONES IN THE AFTERNOON HOURS LOOKING VERY MUCH ON TRACK.
HIGH TEMPERATURES SHOULD MOSTLY PEAK IN THE LOWER 90S ALTHOUGH THE
INCREASE IN HUMIDITY TODAY WILL OCCASIONALLY CAUSE HEAT INDEX VALUES
TO TOP OUT AROUND THE CENTURY MARK.

FINALLY...MORNING REGIONAL SOUNDING ANALYSIS REVEALS ONLY A VERY
MARGINAL RISK FOR MICROBURSTS OR LOCALIZED SEVERE ACTIVITY FROM
TODAYS CONVECTION...WHICH IS NOT WORTH AN INCLUSION IN THE HWO. /BB/

&&

.PREV DISCUSSION... /ISSUED 403 AM CDT SUN AUG 17 2014/

SHORT TERM...TODAY THROUGH MONDAY NIGHT...LOW LEVEL MOISTURE HAS
RETURNED ACROSS THE CWA THIS MORNING AS 07Z SURFACE ANALYSIS IS
SHOWING LOWER 70S DEWPOINTS OVERSPREADING THE AREA. A FEW
THUNDERSTORMS WERE SEEN YESTERDAY AFTERNOON ACROSS THE FAR SOUTH AS
SOMEWHAT OF A SEA BREEZE MANAGED TO WORK ITS WAY NORTH.

GFS/ECMWF ARE STILL IN AGREEMENT THAT A MID LEVEL SHORTWAVE AND ITS
ATTENDANT WEAK COLD FRONT WILL MOVE SSE OUT OF THE MID MS VALLEY
TOWARD THE CWA TODAY. WHILE THE SURFACE BOUNDARY LOOKS TO STAY TO
THE NORTH OF THE AREA...INCREASING COLD AIR ALOFT OVER THE TOP OF
GOOD LOW LEVEL MOISTURE TRANSPORT SHOULD RESULT IN SCATTERED SHOWERS
AND THUNDERSTORMS PRIMARILY OVER THE NORTHERN PORTIONS TODAY AND
OVER THE NORTHERN HALF MONDAY.

MEANWHILE...SURFACE HIGH PRESSURE WILL CONTINUE BUILDING OVER THE NE
GULF OF MEXICO. ANTICYCLONIC FLOW AROUND THIS HIGH WILL BRING A GOOD
ONSHORE FLOW OVER THE LA/MS COASTAL AREAS PROMOTING SEA BREEZE
ACTIVITY OVER THE NEXT COUPLE OF DAYS.

WITH THE SENSIBLE WEATHER TODAY OCCURRING AT OPPOSITE ENDS OF THE
CWA...CENTRAL SECTIONS WILL LOOK TO ONLY RECEIVE ANY CONVECTION THAT
DEVELOPS FROM HEATING OR THAT CAN PROPAGATE IN FROM THE NORTH OR
SOUTH. THIS IS WHERE POPS WILL BE THE LEAST.

MEAGER LAPSE RATES AND VERTICAL TOTALS IN THE LOW/MID 20S SHOULD
KEEP ANY CONVECTION FROM GETTING TOO INTENSE./26/

LONG TERM...TUESDAY THROUGH SUNDAY...DEEP LAYER RIDGING WILL BUILD
ACROSS THE REGION FOR THE MIDDLE PART OF THE WEEK INTO THE WEEKEND.
THE SINKING AIR ASSOCIATED WITH THE RIDGING WILL LIMIT THUNDERSTORM
CHANCES EACH AFTERNOON AND PROHIBIT ANY STORMS AT NIGHT.

THIS PATTERN WILL ALSO LEAD TO A PROLONGED PERIOD OF HEAT WITH HIGHS
EACH DAY IN THE MIDDLE 90S AND PEAK HEAT INDICES FROM 100 TO 105
DEGREES. THIS PERIOD LOOKS TO BE THE LONGEST STRETCH OF MID 90S
HIGHS SO FAR THIS SUMMER. /SW/

&&

.AVIATION...LOW STRATUS HAS BEEN SLOW TO MIX OUT THIS MORNING...BUT
EXPECT VFR CONDITIONS TO DEVELOP AT MOST SITES THIS AFTERNOON WITH
CU FIELDS RISING TO ~5000 FT WITH CONTINUED HEATING. GIVEN LITTLE
CHANGE IN THE PATTERN...WILL FOLLOW PERSISTENCE FOR EARLY MONDAY
MORNING AND FORECAST IFR STRATUS DEVELOPMENT. THE BEST CHANCE FOR
TSRA SHOULD BE AT HBG THIS AFTN INTO THE EARLY EVENING. THERE IS A
CHANCE THAT SHRA/TSRA WILL BEGIN TO AFFECT GLH/GWO TOWARD DAYBREAK
MONDAY AS AN UPPER LEVEL TROUGH MOVES ACROSS. OVERALL...MONDAY WILL
BE A MORE ACTIVE DAY AND EXPECT GOOD POTENTIAL FOR SHRA/TSRA AT ALL
SITES BY AFTN. /EC/
