NWS St. Louis, MO wrote its last area forecast discussion before the first event at Sep 25, 1:19 PM CST, 4 hours 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 219 PM CDT TUE SEP 25 2007 .DISCUSSION... MAIN QUESTION WITH THIS FORECAST WILL BE THE HOW MUCH OF THE CWA WILL SEE RAIN THROUGH TOMORROW NIGHT...AND HOW MUCH WILL IT BE. NAM AND GFS ARE IN DECENT AGREEMENT WITH FRONTAL TIMING...SO FOLLOWED A BLEND OF THE TWO SOLUTIONS. AREA EXTENT OF PRECIPITATION HAS GRADUALLY BEEN INCREASING TODAY BETWEEN THE PRECIPITATION OVER THE SERN HALF OF THE CWA THAT IS BEING GENERATED BY A WEAK IMPULSE MOVING WITHIN A DEEP FETCH OF TROPICAL MOISTURE...AND THE SHRA/TSRA ALONG THE COLD FRONT. SCT TSRA HAS BEEN INCREASING IN INTENSITY THE PAST COUPLE OF HOURS WHERE MLCAPES HAVE INCREASED UP TO 1,500 J/KG WITH NO CINH. DEEP LAYER SHEAR WILL ONLY BE ON THE ORDER OF 15-25KTS LIMITING THE AREAL EXTENT OF ORGANIZED SEVERE WEATHER. MAY SEE ISOLD SVR CELLS THIS AFTERNOON WITH DAMAGING WINDS BEING THE MAIN THREAT GIVEN THAT FREEZING LEVELS ARE HIGH FOR LARGE HAIL...AND LOCALLY HEAVY RAINFALL AS PRECIPITABLE WATERS ARE STILL 2 STANDARD DEVIATIONS ABOVE CLIMO. WILL BE MAINTAINING LIKELY POPS OVER THE REGION TONIGHT AND TOMORROW MORNING AS AREA WILL BE UNDER LARGE SCALE ASCENT ASSOCIATED WITH TROUGH AND AND LOW LEVEL FORCING FROM THE FRONT. THE FRONT WILL BE SLOW TO MOVE SOUTH OVER THE CWA TOMORROW IN RESPONSE TO SECOND SHORTWAVE MOVING ACROSS THE UPPER MIDWEST TOMORROW AFTERNOON...SO WILL MAINTAIN CHANCE POPS OVER THE SERN QUARTER INTO THE EVENING. CLOUDS WILL ALSO BE DIFFICULT TO DISPERSE TOMORROW BECAUSE OF THE SLOW MOVEMENT OF THE FRONT. THESE CLOUDS...AND THE RAIN...WILL EXIT THE REGION BY EARLY THURSDAY MORNING AS THE SECOND TROUGH MOVES EAST OF THE AREA. UNTIL THEN...THE SERN HALF OF THE CWA LOOKS TO HAVE QUARTER TO HALF INCH QPF TOTALS FROM THIS SYSTEM...WITH LOCALLY HEAVIER AMOUNTS WHERE THE TSRA MOVES THROUGH. EXPECT A RETURN TO DRY WEATHER THURSDAY NIGHT INTO SATURDAY AS A LARGE RIDGE BUILDS INTO THE AREA. TEMPERATURES GUIDANCE IS IN PRETTY GOOD AGREEMENT THE NEXT FEW DAYS AND GENERALLY FOLLOWED...THOUGH I DID LOWER IT A FEW DEGREES IN THE SOUTH TOMORROW BECAUSE OF EXPECTED CLOUDS AND RAIN. HAVE FOLLOWED THE GFS ENSEMBLE MEAN IN THE EXTENDED (FRIDAY NIGHT-NEXT TUESDAY) AS IT HAS HAD THE BEST CONTINUITY THE PAST FEW DAYS. WHILE THERE IS A CONSIDERABLE SPREAD OF 500MB HEIGHTS OVER THE MID-UPR MISSISSIPPI VALLEY ON SUNDAY MORNING...THE MEAN TROUGH LOCATION IS NEARLY THE SAME. WITH THIS IN MIND...WILL KEEP A COLD FRONT MOVING ACROSS THE CWA ON SUNDAY ALONG WITH THE BEST CHANCE OF SHRA/TSRA. THE ECMWF DIFFERS DRAMATICALLY FROM YESTERDAYS RUNS IN DEVELOPING A CLOSED LOW OVER THE CENTRAL UNITED SATES LATE IN THE WEEKEND WHICH SLOWS THE FORWARD PROGRESSION OF THE FRONT AS WELL AS THE ONSET OF PRECIPITATION. OTHERWISE...DRY FOR SATURDAY AND ALSO EARLY NEXT WEEK BEHIND THE FRONT. TEMPERATURES ARE A COMBINATION OF THE OPERATION GFS MOS AND THE ENSEMBLE MOS. BRITT && .AVIATION... FOR THE 18Z TAFS... COLD FRONT CURRENTLY EXTENDS FROM NWRN IL THRU NERN MO THEN INTO SERN KS. AHEAD OF FRONT...HAVE VFR CONDITIONS. HOWEVER...AS FRONT AND PCPN MOVE CLOSER TO TAF SITES...WILL SEE CIGS GRADUALLY LOWER. TIMING OF PCPN HAS BEEN DIFFICULT AS FRONT IS MOVING VERY SLOWLY. WILL HAVE PCPN MOVE INTO KUIN/KCOU AT ONSET OF FORECAST PERIOD...WHILE KSUS/KSTL WILL NOT SEE PCPN TIL AT LEAST 23Z. BEHIND FRONT CURRENTLY SEE LOW MVFR CIGS/VSBYS...EVEN SOME IFR CIGS...SO WILL BRING CIGS DOWN MOST LOCATIONS A FEW HOURS BEHIND PASSAGE OF FRONT. FOR KCOU/KUIN...DRIER AIR TO MAKE ITS WAY INTO AREA...SO WILL SEE CIGS SCATTER OUT BETWEEN 08Z AND 10Z...WHILE KSUS/KSTL TO STAY SOCKED IN TIL MID MORNING ON WED...AROUND 15Z. BYRD && .LSX WATCHES/WARNINGS/ADVISORIES... MO...NONE. IL...NONE. && WFO LSX
