13What forecasters said that day
The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Shreveport, LA wrote its last area forecast discussion before this tornado warning went out at Oct 23, 5:36 PM CDT, 26 minutes earlier.
Area forecast discussion, Oct 23, 5:36 PM CDT, 26 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 536 PM CDT SAT OCT 23 2010 .DISCUSSION... ZONES UPDATED TO INCLUDE TORNADO WATCH 706 FOR MUCH OF EAST TEXAS UNTIL 10 PM CDT. NO OTHER CHANGES AT THIS TIME TO FORECAST. PREVIOUS DISCUSSION... SHOWERS AND THUNDERSTORMS FOR THE MOST PART...HAVE REMAINED JUST WEST OF OUR WESTERN MOST ZONES TODAY AS THIS HAS BEEN WHERE THE IDEAL MOISTURE TRANSPORT HAS BEEN IN ADDITION TO THE UPPER LEVEL STORM TRACK. TORNADO WATCH #704 REMAINS IN EFFECT UNTIL 8 PM FOR COUNTIES JUST TO OUR NORTHWEST ACROSS NE TX INTO SE OK. STILL WATCHING STRONG SHORTWAVE JUST NOW BEGINNING TO MOVE NORTH NORTHEAST FROM DEEP SOUTHWEST TEXAS IN THE BASE OF THE UPPER LEVEL TROUGH. THIS SHORTWAVE APPEARS TO BE FAR ENOUGH SOUTH AND EAST INITIALLY SUCH THAT OUR WESTERN ZONES SHOULD FEEL MORE OF AN EFFECT FROM THIS FEATURE LATER THIS EVENING TO NUDGE THE MOISTURE TRANSPORT A LITTLE FURTHER TO THE EAST INTO OUR WESTERN ZONES. WILL CONTINUE TO ADVERTISE LIKELY POPS ACROSS OUR NW ZONES OVERNIGHT BUT SHORT TERM PROGS SUGGEST THAT TSTM COVERAGE WILL WEAKEN IN COVERAGE AND INTENSITY AFTER MIDNIGHT. SEVERE STORMS WILL CONTINUE TO BE POSSIBLE ACROSS OUR EXTREME WEST AND NORTHWEST ZONES AS THIS REGION APPEARS TO BE WHERE THE BEST BULK SHEAR RESIDES NOT TO MENTION INSTABILITY. DAMAGING WIND GUSTS WILL BE THE PRIMARY THREAT THIS EVENING...WITH AN ISOLATED TORNADO/HAIL THREAT ALSO POSSIBLE ASSUMING THAT DEVELOPING CONVECTION DOES NOT OUTRUN THE UPPER LEVEL SUPPORT BEFORE WE BEGIN TO STABILIZE SOMEWHAT LATE TONIGHT. AFTER A WARM NIGHT...WE WILL CONTINUE TO LOOK UPSTREAM DURING THE DAY SUNDAY AS THE UPPER TROUGH AXIS ITSELF BEGINS TO FILL AND KICK OUT INTO THE SOUTHERN PLAINS/LOWER MISS VALLEY. WE MAY BE DEALING WITH SOME ELEVATED SCATTERED CONVECTION SUNDAY MORNING BUT FEEL LIKE THE BEST POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS WILL OCCUR LATE IN THE AFTERNOON...INTO THE EVENING HOURS AND MAINLY ALONG AND NORTH OF THE I-20 CORRIDOR AS THE BEST DYNAMICS WILL BE ACROSS OUR NORTHERN HALF. DEEPER CONVECTION...ROOTED MORE TOWARDS THE SURFACE WILL LIKELY DEVELOP DURING THE AFTERNOON HOURS ALONG A NORTH TO SOUTH ORIENTED DRY LINE ACROSS EASTERN OKLAHOMA INTO NORTH CENTRAL TEXAS. MUCH LIKE TODAY TO OUR WEST...THERE WILL BE SUFFICIENT BULK SHEAR FOR THE DEVELOPMENT OF ORGANIZED SEVERE CONVECTION...MOSTLY IN THE FORM OF LEWP/BOWING SEGMENTS BUT IF ANY DISCRETE CONVECTION CAN DEVELOP EAST OF THE DRYLINE...A TORNADO CANNOT BE RULED OUT GIVEN THE SRH VALUES IN THE 0-1 AND 0-3 KM LAYERS. WE REMAIN IN STRONG WEST SOUTHWEST FLOW ALOFT THROUGH THE EARLY AND MIDDLE PART OF THE WORK WEEK AND WE CANNOT RULE OUT WIDELY SCATTERED CONVECTION JUST ABOUT ANY DAY THROUGH AT LEAST WEDNESDAY NIGHT. UPPER LEVEL PATTERN BECOMES WEST NORTHWEST DURING THE DAY THURSDAY WHICH WILL HELP TO DRIVE A FRONT INTO THE REGION AND RETURN OUR TEMPERATURES MORE TOWARDS CLIMATOLOGICAL LATE OCTOBER NORMALS FOR THE END OF THE WEEK INTO NEXT WEEKEND. PRELIMS TO FOLLOW...13. && .AVIATION... MOSTLY VFR CONDITIONS ARE EXPECTED THROUGH THE AFTERNOON/EARLY EVENING...WITH A BKN CU FIELD EXPECTED TO CONTINUE TO EXPAND N THIS AFTERNOON ACROSS E TX/N LA/EXTREME SRN AR. A LARGE AREA OF SHRA WITH EMBEDDED CONVECTION OVER SRN/ERN OK AND THROUGH MUCH OF N TX WILL CONTINUE TO SLOWLY SPREAD ENE INTO EXTREME SE OK/SW AR/E TX LATE THIS AFTERNOON/EVENING...AHEAD OF A SHORTWAVE EXPECTED TO EJECT NE ACROSS N TX/SE OK THIS EVENING. THIS CONVECTION MAY NOT AFFECT THE TYR TERMINAL UNTIL AFTER 21Z...AND THE TXK TERMINAL UNTIL AFTER 02Z SUNDAY. WILL MAINTAIN CB/S IN FOR GGG...ALTHOUGH AMENDMENTS WILL BE POSSIBLE HERE BY EARLY EVENING. THE CONVECTION MAY BEGIN TO DIMINISH AFTER 06Z AS THE PARENT SHORTWAVE LIFTS NE AWAY FROM THE AREA...ALTHOUGH WARM ADVECTION SHOWERS WILL REMAIN POSSIBLE ACROSS E TX/SW AR/NW LA OVERNIGHT. A 25-30KT SSWRLY LLJ WILL YIELD VARIOUS MVFR CIGS ACROSS MUCH OF THE REGION MAINLY AFTER 06Z...AND WILL NOT LIFT UNTIL MID/LATE MORNING SUNDAY. SCT CONVECTION WILL FIRE ACROSS SE OK/NE TX/SW AR AFTER 18Z...AHEAD OF THE NEXT SHORTWAVE THAT WILL TRANSLATE E ACROSS THE REGION. SSE WINDS AROUND 10KTS TODAY...WITH OCCASIONAL GUSTS UP TO 20KTS THIS AFTERNOON...WILL PERSIST THROUGH THE OVERNIGHT HRS ACROSS E TX/NW LA/SW AR...BUT DIMINISH SLIGHTLY TO 5-10KTS ACROSS NCNTRL LA. /15/ && .PRELIMINARY POINT TEMPS/POPS...
