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 May 7, 5:26 AM CST, 1 hour 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 626 AM CDT MON MAY 7 2007 .UPDATE... QUITE THE BATTLE GOING ON WITH CONVECTIVE LINE PUSHING IN FROM THE WEST. A LINE MERGER OCCURRED NEAR THE KANSAS STATE LINE RIGHT AROUND 6 AM. THIS MERGER HAS ENHANCED THE COLD POOL THAT HAD PREVIOUSLY OUTRUN THE MAIN CONVECTION. A QUICK LOOK AT THE 12Z KSGF RAOB INDICATES TWO CAPS TO OVERCOME IN THE LOWER LEVELS. LATEST RADAR VELOCITY DATA INDICATES THAT THE COLD POOL WOULD BE SUFFICIENT TO OVERCOME THESE CAPS. BEST SHEAR AND COLD POOL INTERACTION IS FAVORED OVER EXTREME SOUTHWEST MISSOURI AND NORTHWEST ARKANSAS. THE INTERESTING FEATURE ON THE RAOB IS THE 10 KFT DRY LAYER THE STORMS ARE ENCOUNTERING. AM THEREFORE EXPECTING THE STORMS TO CONTINUE A WEAKENING TREND AS THEY APPROACH HIGHWAY 65. TOUGH TO SAY WHERE THE RAIN WILL CEASE...SO WILL WATCH CLOSELY OVER NEXT HALF HOUR FOR A POSSIBLE QUICK UPDATE. SCHAUMANN .DISCUSSION... VERY LITTLE CHANGE IN THE HEMISPHERIC AND SYNOPTIC SCALE PATTERNS OVER THE LAST SEVERAL DAYS. A LONG WAVE TROUGH REMAINS OVER THE EASTERN PACIFIC AND WESTERN UNITED STATES. POSITIVE ANOMALIES REMAIN OVER THE CENTRAL UNITED STATES. MODELS FORECAST VERY LITTLE CHANGE TO THIS SETUP THROUGH THE WEEK. GIVEN THIS LONG WAVE SETUP...MODELS CONTINUE TO STRUGGLE WITH THE PLACEMENT AND TIMING OF SYNOPTIC SCALE FEATURES...CONTINUING TO BE HEAVILY INFLUENCED BY CONVECTIVE FEEDBACK. AN ALREADY POSITIVE TILT TO THE WESTERN TROUGH WILL INCREASE AS A BIG CHUNK OF ENERGY PULLS OUT OF THE DESERT SOUTHWEST AND INTO THE DAKOTAS BY TUESDAY. WHAT IS LEFT OF ENERGY OVER THE SOUTHWESTERN UNITED STATES MAY THEN SLOWLY NUDGE NORTHEAST LATER THIS WEEK AS THE SUBTROPICAL JET MAY BECOME A BIT MORE OF AN INFLUENCE. WITH ALL OF THIS SAID...THERE WILL BE LITTLE SYNOPTIC SCALE SUPPORT FOR CONVECTION AT LEAST EARLY THIS WEEK...SO SMALLER SCALE FEATURES WILL BE THE KEY TO GETTING CONVECTION GOING. PINPOINTING THESE FEATURES WILL BE THE MAIN FORECAST CHALLENGE FOR THE IMMEDIATE SHORT TERM. TODAY AND TONIGHT...A LOW LEVEL JET WILL REMAIN THROUGH EARLY THIS MORNING ACROSS EASTERN KANSAS AND WESTERN MISSOURI. NOT OUT OF THE QUESTION TO SEE SOME ISOLATED TO SCATTERED ELEVATED STORMS MAINLY WEST OF HIGHWAY 65 THIS MORNING. MAY SEE ADDITIONAL CONVECTION FIRE THIS AFTERNOON ALONG TWO SURFACE BOUNDARIES. AN OLD OUTFLOW BOUNDARY FROM CONVECTION SUNDAY MORNING REMAINS ORIENTATED FROM NEAR PARSONS TO NEVADA. THIS BOUNDARY MAY GET REINFORCED BY CONVECTION CURRENTLY GOING OVER EASTERN KANSAS. SECOND BOUNDARY IS MORE OF A MOISTURE GRADIENT EXTENDING FROM NORTH TO SOUTH ACROSS THE EASTERN ZONES. THIS BOUNDARY HAS NOT BEEN ALL THAT ACTIVE OVER THE LAST COUPLE OF DAYS. HAVE PAINTED MAINLY CHANCE POPS TO COVER THE LOW LEVEL JET CONVECTION THIS MORNING AND OLD OUTFLOW BOUNDARY. PLACED SLIGHT CHANCE POPS MAINLY SOUTH OF INTERSTATE 44. AGAIN EXPECT MODERATE INSTABILITY TODAY WITH A FAIRLY WEAK CAP. 0-6KM BULK SHEAR MAY PUSH 30 KNOTS OR SO ALONG AND NORTH OF THE INTERSTATE 44 CORRIDOR. WILL THEREFORE SEE A SIMILAR SEVERE THREAT TO THAT OF SUNDAY...HAIL TO THE SIZE OF QUARTERS AND WIND GUSTS TO 60 MPH. SAW NO REASON TO STRAY TOO FAR FROM HIGH TEMPERATURES ON SUNDAY...BUT DID TRIM THINGS BACK A FEW DEGREES OVER SOUTHWEST MISSOURI AS 850/925MB TEMPERATURES HAVE COOLED EVER SO SLIGHTLY. AGAIN EXPECT MOST OF THE CONVECTION TO DIMINISH AFTER DARK. DO NOT EXPECT THE LOW LEVEL JET TO DEVELOP AGAIN TONIGHT...SO SAW NO REASON TO GO ANYTHING HIGHER THAN LOW CHANCE POPS OVER THE WESTERN ZONES. TUESDAY THROUGH THURSDAY...THERE APPEARS TO BE ONLY TWO REAL MECHANISMS FOR GETTING CONVECTION GOING. FIRST WOULD BE DAYTIME HEATING AND ANY KIND OF FORCING THAT CAN BE GENERATED BY A SMALLER SCALE BOUNDARY. NO WAY TO PREDICT THIS OUT THAT FAR. SECOND MECHANISM WOULD BE ANY CONVECTION THAT WOULD FIRE TO OUR SOUTHWEST AND MOVE INTO THE OZARKS. NOT BANKING TOO HARD ON EITHER OF THESE...SO HAVE KEPT POPS IN THE SLIGHT TO LOW CHANCE RANGE. KEPT TEMPERATURES WARM AS LITTLE CHANGE IS EXPECTED IN THE AIRMASS. AS A MATTER IN FACT...THERE IS A CHANCE THAT THE EASTERN ZONES MAY WARM UP A FEW DEGREES. THIS WOULD BE MOSTLY ATTRIBUTED TO THE UPPER LEVEL RIDGE INTENSIFYING AS IT GETS SQUEEZED BETWEEN THE WESTERN TROUGH AND A STRONG LOW OFF THE SOUTHEAST COAST. LATE THIS WEEK...WILL NEED TO KEEP A WATCH ON WHAT IS LEFT OF THE SOUTHWEST ENERGY. IT MAY EVENTUALLY PASS IN CLOSE ENOUGH PROXIMITY TO BRING A SYNOPTIC SCALE FRONT AT LEAST TOWARDS OUR NORTHWEST ZONES. KEPT TEMPERATURES AT OR SLIGHTLY ABOVE GUIDANCE FOR NOW...UNTIL DETAILS BECOME CLEARER ON IF AND WHEN THE FRONT WILL PLAY A ROLE. KEPT POPS IN THE 20 TO 30 PERCENT RANGE THROUGH FRIDAY TO COVER THE APPROACHING SOUTHWEST ENERGY AND POSSIBLE FRONT. SCHAUMANN && .AVIATION... FOR THE 06Z TAF PACKAGE...WINDS WILL CONTINUE TO BE GUSTY... ESPECIALLY IN THE FUNNEL AFFECT NEAR THE SGF AERODROME. AS DISCUSSED ABOVE...CONVECTION WILL EDGE INTO FAR WESTERN MO...BUT NOT MUCH FARTHER. WILL INCLUDE A MENTION OF THUNDER AT THE JLN AERODROME AFTER MIDNIGHT...BUT KEEP CONDITIONS DRY AT SGF. MVFR CIG/VIS MORE PROBABLE AT JLN ASSOCIATED WITH ANY TSRA THE MOVE INTO THIS AREA...OTHERWISE VFR CONDITIONS WILL CONTINUE. GAGAN && SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. WFO SGF
