NWS St. Louis, MO wrote its last area forecast discussion before the first event at Jul 6, 2:30 AM CST, 7 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 330 AM CDT TUE JUL 6 2004 .DISCUSSION... MAIN CONCERN FOR THIS FORECAST DEALS WITH TIMING AND SEVERITY OF TSRA TODAY. PLAN ON ISSUING A FLOOD WATCH FOR THE ST. LOUIS METRO AREA FOR TODAY. ONCE AGAIN...SHORT RANGE MODELS ARE SHOWING DECENT AGREEMENT WITH SYNOPTIC SCALE MASS FIELDS OVER THE REGION. HOWEVER...WEATHER TODAY AND TONIGHT WILL BE DRIVEN MORE BY HOW ONGOING CONVECTION OVR THE CNTRL CONUS EVOLVES THIS MORNING...AND HOW IT EFFECTS ADDITIONAL TSRA DEVELOPMENT THIS AFTERNOON. GFS IS SHOWING CONVECTIVE FEEDBACK PROBLEMS...PARTICULARLY OVR OK/AR BY 12Z WED WHICH RESULTS IN THE FARTHER N PLACEMENT OF QPF OVR SRN MO/SRN IL 06-12Z TONIGHT. SO HAVE LEANED TOWARD THE ETA WITH ONLY MARGINAL CONFIDENCE IN FORECAST FOR TODAY. TSRA DEVELOPMENT JUST WONT STOP OVER E CNTRL MO EARLY THIS MORNING. STORMS CONTINUE TO DEVELOP WHERE BROAD BAND OF 925-850MB THETA-E ADVECTION/MOIST CONVERGENCE IS INTERSECTING CONVECTIVE OUTFLOW. ALSO SEEING W-E ORIENTED BATCH OF TSRA DEVELOPING AHEAD OF MCS OVR ERN KS INTO WRN MO WHICH EXTENDS ALL THE WAY E TO THE CONVECTION OVR THE STL METRO. SO IN THE SHORT TERM...THINK THAT MCS OF KS WILL MOV EWD INTO CWA THIS MORNING...WITH CONTINUE DEVLOPMENT IN THE E-W BAND AHEAD OF IT. GIVEN THE HEAVY RAINFALL SEEN IN THE IMMEDIATE STL METRO THE LAST 6 HOURS...ONGOING AND EXPECTED CONTINUED CELL TRAINING COULD LEAD TO FLOODING PROBLEMS IN THE METRO. ALSO INSTABILITY AND 30KT DEEP LAYER SHEAR SUGGEST ANOTHER ROUND OF SEVERE WEATHER THIS MORNING...AND AGAIN THIS AFTERNOON AS SECOND MID-LEVEL SHORTWAVE TROUGH AND SFC COLD FRONT MOVES INTO CWA. DEVELOPMENT OF TSRA THIS AFTERNOON WILL DEPEND ON WHERE BOUNDARIES FROM MORNING CONVECTION SETS UP. FRONT PUSHES SEWD THIS EVENING...ENDING CHC OF RAIN AFTER 06Z TONIGHT IN MOST LOCATIONS. AS MENTIONED ABOVE...WILL IGNORE THE 00Z GFS IDEA OF KEEPING PRECIP IN SRN ZONES OVERNIGHT. OTHERWISE...LEFT FORECAST PRETTY MUCH THE SAME. USED A BLEND OF GUIDANCE FOR TEMPERATURES. && .LSX WATCHES/WARNINGS/ADVISORIES... .MO...FLOOD WATCH FOR TODAY FOR WARREN...ST CHARLES...FRANKLIN...
