The remnants of a weak tropical circulation over Louisiana spread deep moisture into the Ozarks. This interacted with a stalled front and numerous outflow boundaries which produced persistent, heavy rain producing, thunderstorms across the region.

NWS Springfield, MO wrote its last area forecast discussion before the first event at Jul 6, 5:16 AM CST, 44 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 616 AM CDT TUE JUL 6 2010 ...UPDATE TO AVIATION... .DISCUSSION... TOUGH FORECAST FOR THE NEXT SEVEN DAYS AS MODELS CONTINUE TO STRUGGLE WITH THE SYNOPTIC SCALE. THIS DOES NOT BODE WELL FOR THE SMALLER SCALE...WHICH WILL PLAY A BIG PART IN PRECIPITATION CHANCES THROUGH THE END OF THE WEEK. MESOSCALE TYPE FEATURES WILL BEST BE ASSESSED IN THE 12 TO 24 HOUR PERIOD. THE LARGE SCALE PATTERN WILL UNDERGO CHANGES OVER THE NEXT FIVE DAYS. LONG WAVE CHARTS CONTINUE TO ADVERTISE INCREASING POSITIVE HEIGHT ANOMALIES JUST OFF THE WEST COAST. THIS WILL TEND TO VEER THE UPPER LEVEL FLOW FROM SOUTHWESTERLY TO WEST NORTHWESTERLY BY THE WEEKEND. POPS WERE THE MAIN FORECAST CONCERN...BUT TEMPERATURES WILL BE NO PICNIC EITHER AS CLOUDS AND PRECIPITATION WILL HAVE BIG IMPACTS. CURRENTLY...WATER VAPOR IMAGERY AND THE REGIONAL PROFILER NETWORK INDICATE A SHEAR AXIS EXTENDING FROM NORTHEASTERN KANSAS INTO CENTRAL OKLAHOMA. WE HAVE SEEN SCATTERED CONVECTION IN THIS CORRIDOR OVERNIGHT...PARTIALLY AIDED BY WEAK PRESSURE ADVECTION AND FAVORABLE POSITIONING OF AN UPPER LEVEL JET STREAK. THE ATMOSPHERE REMAINS QUITE MOIST WITH PRECIPITABLE WATER VALUES AT OR ABOVE TWO INCHES. VALUES DROP OFF VERY QUICKLY ONCE YOU GET INTO SOUTHEASTERN MISSOURI. TALL AND SKINNY CAPE IS PRESENT...MAKING FOR VERY EFFICIENT RAINFALL PRODUCERS. NOT EXPECTING HUGE CHANGES IN THE OVERALL SENSIBLE WEATHER FOR THE NEXT 24 HOURS. A SYNOPTIC SCALE FRONT WILL REMAIN WEST OF THE REGION ACROSS CENTRAL KANSAS. ALTHOUGH HEATING TODAY MAY BE SOMEWHAT SLOWED BY CLOUD COVER...STILL EXPECT TEMPERATURES TO WARM ENOUGH FOR CONVECTIVE TEMPERATURES TO BE APPROACHED. THEREFORE EXPECT MORE SHOWER ACTIVITY AROUND. MAY SEE SHOWERS A BIT MORE WIDESPREAD ACROSS THE WEST CLOSER TO THAT SHEAR AXIS. ONE CHANGE THAT WILL BEGIN TO TAKE PLACE IS A SHIFT IN MOISTURE TRANSPORT. TRAJECTORIES WILL SHIFT FROM SOUTHWESTERLY TO SOUTHEASTERLY ONCE WE GET INTO WEDNESDAY. MAY NEED TO WATCH FOR A FEW PRESSURE ADVECTION SHOWERS TONIGHT. MEANWHILE...SHORT WAVE ENERGY WILL BEGIN TO TRAVERSE EAST ACROSS THE NORTHERN PLAINS ON WEDNESDAY. THIS WILL SUPPORT THAT FRONT ACROSS CENTRAL KANSAS BEGINNING TO NUDGE EAST. THAT TEMPORARY SHIFT IN MOISTURE TRAJECTORY MAY THEN COME INTO PLAY AS IT INTERSECTS FAVORABLY WITH THAT FRONT. WILL HAVE TO WATCH THIS CLOSELY FROM WEDNESDAY NIGHT INTO AT LEAST THURSDAY FOR POSSIBLE HEAVY RAINFALL POTENTIAL. CONTINUE TO PREFER SLOWER MOVEMENT OF THAT FRONT AS THE MAIN SYNOPTIC ENERGY/HEIGHT FALLS REMAIN TO OUR NORTH. THEREFORE KEPT CHANCE POPS GOING THROUGH AT LEAST FRIDAY. BOTH THE 00Z GFS AND ECMWF PUSH THE FRONT TO AT LEAST INTERSTATE 40 BY THE WEEKEND. ALTHOUGH VEERING UPPER LEVEL FLOW SUPPORTS THIS PROGRESSION... CLIMATOLOGY DOES NOT. MAINTAINED LOW POPS ACROSS SOUTHERN MISSOURI FOR NOW. DO NOT SEE A BIG TEMPERATURE DIFFERENCE BEHIND THE FRONT...BUT DEW POINTS SHOULD COME DOWN SOME. GENERALLY FOLLOWED VERY CLOSE TO MODEL CONSENSUS FOR TEMPERATURES. SCHAUMANN && .AVIATION... 12Z TAFS... RATHER MESSY AVIATION FORECAST TODAY...WITH MAIN CONCERN BEING CHANCES FOR SHRA/TSRA THROUGHOUT THE DAY. SCATTERED SHRA/TSRA ONGOING THIS MORNING...BUT WITH VERY LITTLE IN THE WAY OF A FOCUSING MECHANISM AT THE SURFACE...WILL BE PARTICULARLY DIFFICULT TO PIN DOWN EXACT TIMING OR STRENGTH OF CONVECTION AT ANY GIVEN TERMINAL THROUGHOUT THE DAY. EXPECT THIS TREND TO CONTINUE AS DIURNAL DESTABILIZATION TAKES PLACE THROUGHOUT THE DAY TODAY...SO HAVE JUST MAINTAINED VCTS MENTION THROUGH THE DAY TO ACCOUNT FOR UNCERTAIN CHANCES. ANY SITE THAT DOES EXPERIENCE TSRA CAN EXPECT A DROP INTO MVFR CIGS AND VIS...AND THE CHANCE FOR PERIODS OF IFR IN THE AREAS OF HEAVIEST CONVECTION. OTHERWISE TODAY...WEAK SURFACE FLOW SHOULD KEEP WINDS OUTSIDE OF SHRA/TSRA LIGHT AND SOUTHERLY...AND SHOULDN'T HAVE ANY SIGNIFICANT EFFECT ON OPERATIONS. FOR TONIGHT...FEW TO SCATTERED SHRA/TSRA MAY REMAIN POSSIBLE THIS EVENING AND OVERNIGHT...OTHERWISE EXPECT VFR CONDITIONS. BOXELL && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
