The episode as NWS SHV wrote it up.
Yet another complex of strong thunderstorms moved into portions of southwest Arkansas from the northwest during the day. These thunderstorms weakened as they moved southeast...yet due to the high moisture content...the storms produced very heavy flood producing rainfall.
The local office's own words before the first event, 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 the first event at Jul 13, 8:53 AM CST, 2 hours 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 953 AM CDT FRI JUL 13 2007 .DISCUSSION... AREA RADARS SHOW DIMINISHING MCS CONTINUES TO WORK SE INTO THE NORTHERN ZONES. MAIN CONCERNS RIGHT NOW AREA W-E PARALLEL ORIENTATION OF HEAVY RAINFALL TO THE RED RIVER. THIS WILL ONLY EXACERBATE FURTHER OVER THE NEXT 24 HRS. ALSO...LATEST NAM FORECAST SOUNDINGS STILL PUSH PWATS OVER THE 2 INCH MARK THIS AFTERNOON...SO WE MAY ISSUE A FFA W/THE AFTERNOON PACKAGE. FOR NOW...12Z KSHV SOUNDING AND SATELLITE IMAGERY/CLOUD COVER INDICATE AFTERNOON TEMP GRIDS LOOK GOOD. NO UPDATE. && .AVIATION... THUNDERSTORM COMPLEX DRAWING NEAR TO I 30 FROM THE NW. MAY WEAKEN AS IT MOVES SOUTHEAST BUT WILL DROP BOUNDARIES THAT WILL HELP FIRE AFTERNOON CONVECTION. MOSTLY VFR CONDITIONS EXPECTED EXCEPT MVFR AND GUSTY WINDS WITH CONVECTION. MAY ALSO SEE MVFR OR SPOTTY IFR CONDITIONS DURING THE MORNING HOURS SATURDAY. /17/ && .PREV DISCUSSION... /ISSUED 450 AM CDT FRI JUL 13 2007/ DISCUSSION... NW FLOW IS GIVING ME HEADACHES THIS MORNING WITH THE FORECAST...AS PROGS HAVE DONE OF POOR JOB WITH THE INITIALIZATION OF THE MCS OVER OK...ALTHOUGH THE 00Z/06Z RUN OF THE NAM THURSDAY MORNING DID WELL WITH THE DEVELOPMENT OF SCATTERED CONVECTION ACROSS SE OK/SW AR EARLIER THIS MORNING. GIVEN INCONSISTENCIES IN THE MODELS THIS MORNING...WILL REMAIN RATHER CONSERVATIVE WITH THE FORECAST...WITH LITTLE CONFIDENCE IN PINPOINTING THE MORE WIDESPREAD AREAS FAVORED FOR POTENTIALLY HEAVY RAINFALL...GIVEN THE UNCERTAIN MESOSCALE AND SYNOPTIC FEATURES EXPECTED TO BE IN PLACE THIS WEEKEND. OK MCS HAS BECOME MORE OUTFLOW DOMINANT OVER THE LAST CPL. HRS...RACING SWD INTO S OK AND TOWARDS N TX...WHERE GREATER SFC BASED INSTABILITY IS BASED. AIR MASS OVER THE REGION IS QUITE A BIT MORE STABLE...IN WAKE OF CONVECTION THURSDAY EVENING...AND ASSOCIATED OUTFLOW BOUNDARIES WHICH RAN RAMPANT ACROSS THE REGION. 9Z MSAS ANALYSIS INDICATES A WEAK SURFACE TROUGH EXTENDING FROM A SFC LOW NEAR SPS...WHICH RAN SE ACROSS EXTREME NE TX INTO NW LA. SFC THETA-E ANALYSIS ALSO CONTINUES TO INDICATE ANOTHER SURFACE BOUNDARY EXTENDING FROM ECNTRL OK INTO CNTRL AR...IN VC OF AN 850MB THETA-E AXIS WHICH CONTRIBUTED TO THE TRAINING CONVECTION EARLIER THIS MORNING OVER SW AR. CURRENT MCS WILL LIKELY REINFORCE THE NE TX SURFACE TROUGH S A BIT THIS MORNING...WHICH WILL BECOME A FOCUS FOR CONVECTION THROUGH THE DAY AS SHORTWAVE ENERGY CONTINUES TO DROP SE ACROSS OK/N TX TODAY. DID CONTEMPLATE A FLASH FLOOD WATCH FOR SE OK/EXTREME NE TX TODAY...BUT STABILITY OF OUR AIR MASS...AND MORE SWD PROGRESSION OF THE CURRENT MCS TOWARDS THE BETTER INSTABILITY ACROSS S OK/N TX LEADS ME TO BELIEVE THAT THE LOCALIZED FLOODING THREAT THROUGH MUCH OF TODAY WILL REMAIN OVER JUST A SMALL PORTION OF THE AREA. HOWEVER...DID INCLUDE HEAVY RAINFALL MENTION FOR SE OK/SW AR/EXTREME NE TX TODAY...IN VC OF THE TWO AFOREMENTIONED BOUNDARIES. ELSEWHERE...SCATTERED CONVECTION IS EXPECTED BY AFTERNOON WITH ADDED HEATING/OUTFLOW INTERACTION. SHORTWAVE TROUGH IS EXPECTED TO APPROACH THE RED RIVER VALLEY OF SE OK/NE TX LATE THIS AFTERNOON PER THE GFS/NAM...ALTHOUGH THE NAM/UKMET REMAINS CONSISTENT FROM ITS RUNS THURSDAY IN PROGRESSING THE TROUGH TO THE COAST. HOWEVER...THE GFS REMAINS A BIT SLOWER...BUT ALL MODELS DO COMPROMISE A SOLUTION IN MAINTAINING SUBTLE TROUGHINESS OVER NE TX/SW AR...BECOMING BETTER AMPLIFIED THIS WEEKEND. PW/S EXPECTED TO REMAIN AOA 2 THIS WEEKEND...THUS AFTERNOON HEATING/LEFTOVER MESOSCALE BOUNDARIES AND POTENTIAL GRADUAL DEEPENING OF THE TROUGH/CLOSED LOW WILL ENHANCE CONVECTION COVERAGE. HEAVY RAINFALL CERTAINLY POSSIBLE THIS WEEKEND...BUT GIVEN THE INCONSISTENCIES IN THE EXACT POSITION OF THE TROUGH/ITS DEVELOPMENT AS A FOCUSING MECHANISM...WILL OPT TO MAINTAIN HEAVY RAINFALL MENTION/POTENTIAL FLOODING IMPACTS IN THE MORNING HWO...RATHER THAN IN THE CURRENT FORECAST. MEDIUM RANGE GUIDANCE CONTINUES TO MAINTAIN THIS PERSISTENT PATTERN OF TROUGHINESS OVER NE TX/SW AR/NW LA THROUGH AT LEAST LATE MONDAY...BEFORE THE SUBTROPICAL BERMUDA RIDGE BEGINS TO RETROGRADE W OVER THE SE/GULF COAST STATES. THIS WILL IN EFFECT ALLOW THE TROUGHING PATTERN TO SHIFT W ACROSS TX THROUGH MIDWEEK...THUS TAPERING OUR RAIN CHANCES FROM E TO W...AND ALLOWING SOME OF THE HOTTEST TEMPS THIS SUMMER SEASON TO BUILD IN BY LATE WEEK. HAVE ADJUSTED POPS/TEMPS IN THE EXTENDED TO REFLECT THIS THINKING. PRELIMS ARE NEXT... 15 AVIATION... UNDER INFLUENCE OF AN INCREASING NW FLOW ALOFT...SCATTERED TSTMS ALONG THETA-E AXIS ACROSS NORTHERN FRINGE OF CWA...NOT DIMINISHING AT ALL OVERNIGHT. THIS ARCING AXIS WILL LIKELY SLOWING SHIFT SOUTHWARD DURG THE MORNING HOURS. WITH TEMP/DEWPOINT SPREADS OF 2 TO 6 DEGREES...MAY SEE SOME PATCHY FOG LATER TONIGHT.
