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 Springfield, MO wrote its last area forecast discussion before the first event at Sep 19, 11:23 PM CST, 37 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 1223 AM CDT SUN SEP 20 2009 ...UPDATE TO AVIATION... .UPDATE... A LOCALIZED FLASH FLOOD EVENT CONTINUES THIS EVENING OVER NORTHERN BARRY AND LAWRENCE COUNTIES. RAINFALL TOTALS ARE LIKELY EXCEEDING SIX INCHES IN SOME CASES OVER EASTERN LAWRENCE COUNTY. UNFORTUNATELY...LATEST RADAR TRENDS INDICATE THE HEAVY RAINFALL WILL CONTINUE FOR AT LEAST ANOTHER HOUR. THERE HAS ACTUALLY BEEN RECENT DEVELOPMENT FARTHER TO THE EAST ACROSS EXTREME SOUTHWEST GREENE AND THE CHRISTIAN COUNTY PANHANDLE. LATEST SATELLITE TRENDS CONTINUE TO INDICATE A DIVERGENT AREA CENTERED OVER SOUTHWEST MISSOURI...WITH A THETA E MAXIMA EXTENDING BACK TOWARDS OKLAHOMA. IT IS QUITE POSSIBLE THAT THE OZARK PLATEAU IS PLAYING A ROLE WITH THE KSGF VWP SHOWING A FAVORABLE PROFILE FOR UPSLOPE FROM SOUTHWESTERN GREENE COUNTY INTO BARRY COUNTY. THE 00Z KSGF RAOB IS VERY TELLING WITH NEAR SATURATION UP THROUGH AND ABOVE THE FREEZING LEVEL. WARM RAIN PROCESSES ARE INDEED AT WORK WITH VERY EFFICIENT RAINFALL RATES. PRECIPITABLE WATERS CAME IN RIGHT AROUND 1.75 INCHES. THEREFORE DO NOT SEE AN END TO THE HEAVY RAINFALL THREAT ALONG THE SOUTHERN OZARK PLATEAU INTO THE EARLY OVERNIGHT HOURS. SCHAUMANN && .DISCUSSION... AN ACTIVE WEATHER PATTERN THROUGH THE FORECAST PERIOD WITH SEVERAL CHANCES FOR PRECIPITATION IS THE FORECAST HIGHLIGHT. THE PERSISTENT UPPER LEVEL LOW THAT HAS BROUGHT SCATTERED SHOWERS AND THUNDERSTORMS TO THE LOWER MISSISSIPPI VALLEY THROUGH MOST OF THE WEEK IS BEGINNING TO KICK NORTHEAST TOWARDS THE OHIO VALLEY WITH A DIGGING UPPER TROUGH OVER THE PACIFIC NORTHWEST. STRONG ISENTROPIC UPGLIDE ALONG THE 310K SURFACE HAS PRODUCED NUMEROUS RAIN SHOWERS ACROSS SOUTHERN MISSOURI. RAIN CHANCES WILL CONTINUE TONIGHT ALONG WITH SLIGHT CHANCES FOR SUNDAY WITH THE LOW EJECTING EAST. FOCUS OF THE FORECAST THEN TURNS TO A STRONG COLD FRONT ASSOCIATED WITH A DIGGING UPPER TROUGH IN THE PLAINS EARLY NEXT WEEK. AHEAD OF THIS UPPER TROUGH...THE FRONT WILL INTERACT WITH GULF MOISTURE SURGING NORTH. FORECAST PROGS OF STEEPENING LAPSE RATES AND MARGINAL SHEAR SHOULD BE SUFFICIENT FOR AT LEAST A FEW STRONG THUNDERSTORMS WITH A PRIMARY RISK OF HAIL FOLLOWED BY WIND. WITH PRECIPITABLE WATER VALUES PROJECTED OVER AN INCH AND A HALF...FLASH FLOODING WILL BE A CONCERN ESPECIALLY WHERE THUNDERSTORMS TRAIN ALONG THE FRONT AND WHERE THE STRONGER UPDRAFTS DEVELOP. THE NUMERICAL MODELS CONTINUE TO OFFER A VARIETY OF SOLUTIONS WITH THE EVOLUTION OF THE UPPER TROUGH THROUGH THE WEEK. MODEL CONSENSUS IS FOR THE DEVELOPMENT OF A CUTOFF UPPER LEVEL LOW. HOWEVER...CONSENSUS FROM THERE DIVERGES GREATLY ON THE TRACK OF THE LOW. SOLUTIONS VARY FROM THE GFS...ALONG WITH THE GFS ENSEMBLES RETROGRADING THE LOW TO THE DESERT SOUTHWEST TO THE UKMET AND CANADIAN MODELS STALLING THE LOW OVER KANSAS. NEEDLESS TO SAY...EVENTUAL TRACK OF THE LOW WILL HAVE BIG IMPLICATIONS ON THE EXTENDED FORECAST. CURRENT FORECAST FAVORS THE ECMWF WHICH IS A REASONABLE COMPROMISE BETWEEN THE OUTLIERS. FURTHER ADJUSTMENTS AND REFINEMENT TO THE EXTENDED FORECAST WILL BE MADE TO INCREASE OR DECREASE PRECIPITATION CHANCES ONCE MODEL CONTINUITY STRENGTHENS. ANGLE && .AVIATION... LIFR CONDITIONS WILL PERSIST AT KBBG INTO EARLY SUNDAY MORNING BEFORE FLIGHT CATEGORIES SLOWLY IMPROVE THROUGHOUT THE DAY. FLIGHT CATEGORIES ARE A BIT MORE IN QUESTION AT KSGF AND KJLN THROUGH SUNDAY MORNING. CURRENT THINKING IS THAT MVFR CEILINGS WILL PREVAIL INTO EARLY SUNDAY MORNING AT BOTH TERMINALS. BRIEF IFR VISIBILITIES WILL BE POSSIBLE WITH HEAVIER SHOWERS AROUND KSGF. THERE IS ALSO A SLIGHT CHANCE WE COULD SEE SOME STRATUS BUILD DOWN ALONG THE OZARK PLATEAU. WAS NOT CONFIDENT ENOUGH TO INCLUDE IN THE KSGF TAF...BUT THIS POTENTIAL SCENARIO WILL BE CLOSELY MONITORED. SCHAUMANN && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
