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 St. Louis, MO wrote its last area forecast discussion before the first event at May 25, 3:47 PM CST, 1 hour 13 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 447 PM CDT MON MAY 25 2009 .DISCUSSION... /416 PM CDT MON MAY 25 2009/ VERTICALLY STACKED UPPER LOW IS CONTINUING ITS SLOW DRIFT ACROSS THE CENTRAL U.S. THIS AFTERNOON AND HAS SPUN ITS WAY INTO EXTREME SW MO. EXPECT THE SYSTEM TO MAINTAIN A NWD DRIFT OVERNIGHT AND INTO TUESDAY...THEN GET CAUGHT UP IN THE WESTERLIES AND BEGIN ITS SLOW EXIT FROM THE REGION. PREFER THE ECMWF AND WRF/NAM SPECIFICS OF THE LOCATION OF THE LOW...AS IT STILL LOOKS LIKE THE GFS BEGINS THE EWD MOVEMENT OF THE SYSTEM A BIT TOO SOON. WITH NEARLY SATURATED AMS...PCPN THREAT WILL REMAIN QUITE HIGH THROUGH TUESDAY AS THE SYSTEM WOBBLES ITS WAY ACROSS THE REGION... ALTHOUGH TRYING TO PINPOINT THE LOCATION AND TIMING OF THE HIGHEST POPS REMAINS QUITE DIFFICULT. I THINK THAT THERE WILL BE A FAIRLY LARGE DIURNAL COMPONENT TO THE PCPN TRENDS TONGIGHT THROUGH TUESDAY. HOWEVER...WITH THE CENTER OF THE LOW PASSING OVER WESTERN MO I DID KEEP POPS VERY HIGH OVER THE WESTERN 2/3 OF THE CWA THROUGHOUT THE NIGHT TONIGHT...AND CONFINED THE PRIMARY DIURNAL SWING TO EASTERN SECTIONS OF THE FA. CERTAINLY...OUR MAIN CONCERN FOR LOW-TOPPED SUPERCELLS PRODUCING BRIEF SPIN UPS WILL BE OVER THE NEXT FEW HOURS IN THE VICINITY OF THE SFC TROF WHICH EXTENDS FROM S CNTRL MO INTO S IL. PRECIPITATION THREAT SHOULD GRADUALLY DIMINISH TUESDAY NIGHT THROUGH WEDNESDAY AS THE LOW OPENS UP AND BEGINS TO PUSH EAST. HOWEVER...WILL CARRY POPS UNTIL EARLY THURSDAY WHEN THE SECOND TROF PASSES. THIS MAY BE A BIT TOO SLOW...BUT WITH THE SLUGGISH UA FLOW OVER AREA TRENDING SLOW SEEMS WISE ATTM. NO BIG AMS CHANGES IN THE OFFING...SO TEMP TRENDS WILL CONTINUE TO BE HIGHLY DEPENDENT ON CLOUDS AND PRECIP. MET MOS HAS BEGUN TO DROP TEMPS BEHIND THE PASSAGE OF THE WEAK COLD FRONT ON WEDNESDAY. I DID DROP TEMPS SOME OVER THE NW SECTIONS OF THE FA...BUT DID NOT GO AS LOW AS MET AS THIS DROP SEEMS A BIT OVERDONE...AND ANY SUNSHINE THAT OCCURS BEHIND THE FRONT COULD EASILY MODIFY THE AMS. GENERALY WENT WITH DRY CONDITIONS FOR THE MEDIUM RANGE AS WESTERLIES REMAIN ANCHORED N OF OUR AREA...WITH TEMPS REMAINING ON THE MILD SIDE. TRUETT && .AVIATION... /1236 PM CDT MON MAY 25 2009/ FOR THE 18Z TAFS... IFR CIGS HAVE GENERALLY SCATTERED OUT SOUTH OF THE I-70 CORRIDOR. HOWEVER...SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO AFFECT THE BI-STATE THROUGH THE AFTERNOON. RAIN HAS DEFINITELY BEEN HEAVY ENOUGH TO BRING VSBYS DOWN TO 1SM AT TIMES...AND CIGS AOB 1000FT ARE ALSO LIKELY. SHOULD SEE CONVECTIVE ACTIVITY WANE AFTER SUNSET...BUT EXPECT IFR/LIFR STRATUS TO REDEVELOP BETWEEN 04Z-06Z DUE TO VERY MOIST AIRMASS OVER THE REGION. CARNEY && .LSX WATCHES/WARNINGS/ADVISORIES...
