NWS St. Louis, MO wrote its last area forecast discussion before the first event at Aug 7, 2:15 PM CST, 2 hours 35 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 315 PM CDT MON AUG 7 2006 .DISCUSSION... A COLD FRONT EXTENDING FROM THE SOUTHERN TIP OF LAKE MICHIGAN SOUTHWEST TO JUST NORTH OF ST LOUIS...THEN WEST THROUGH WEST CENTRAL MISSOURI. AND SOUTHWEST TO SOUTH OF WICHITA KS. THE FRONT IS SLOWING AND SHOULD MOVE VERY LITTLE THIS EVENING. AN OUTFLOW BOUNDARY FROM THIS MORNINGS ACTIVITY DROPPED SOUTHEAST INTO SOUTHEAST MISSOURI WEST TO NEAR SPRINGFIELD. THE AIR IS MODERATELY UNSTABLE ACROSS SOUTHERN MISSOURI AND THUNDERSTORMS HAVE BEEN DEVELOPING THIS AFTERNOON FROM PICKNEYVILLE IN SOUTHERN ILLINOIS WEST THROUGH FARMINGTON AND TO LAKE OF THE OZARKS. THESE STORMS SHOW LITTLE MOVEMENT AND NEW STORMS WILL PROBABLY DEVELOP ALONG EITHER SIDE OF THE STORMS ALONG THE OUTFLOW BOUNDARIES. MEANWHILE A SOMEWHAT ORGANIZED LINE OF STORMS EXTENDS FROM DECATUR ILLINOIS WEST SOUTHWEST TO ABOUT 25 MILES SOUTH OF QUINCY TO 30 MILES NORTH OF COLUMBIA. THESE STORMS ARE A BIT CLOSER TO THE WESTERLIES AND THEREFORE HAVE AN EASTWARD MOVEMENT OF 20 KNOTS OR SO. MID AFTERNOON TEMPERATURES HAVE RISEN INTO THE LOWER TO MIDDLE 90S OUTSIDE THE RAIN AREAS WITH HEAT INDICES HOVERING JUST BELOW ADVISORY CRITERIA AGAIN...FROM UPPER 90S TO 104. THE RUC MODEL SHOWS A LOW LEVEL JET FORMING TONIGHT OVER WESTERN KANSAS AND NEBRASKA. FOR NOW WE LOOK FOR CHANCE PROBABILITIES THROUGH THE EVENING HOURS WITH THE SCATTERED THUNDERSTORMS AND THEN A STORM COMPLEX OR MCS IS EXPECTED TO FORM OVER NORTHERN KANSAS AND NEBRASKA DURING THE EVENING AND MOVE EAST INTO NORTHERN MISSOURI DURING THE NIGHT. THE CORFIDI VECTORS HOWEVER SHOW A POSSIBILITY OF A SLIGHT SOUTHWARD SHIFT DURING THE NIGHT AND IN ADDITION THE STATIONARY FRONT MAY PROVIDE ADDITIONAL FOCUS FOR THUNDERSTORM DEVELOPMENT TONIGHT. WINDS ALOFT ARE VERY LIGHT AND THE THREAT OF ANY SEVERE WEATHER IS MINIMAL...ONLY BRIEF STRONG GUSTS NEAR THE STRONGER STORMS. THE TEMPERATURES ALOFT ARE EXTREMELY WARM AND THEREFORE THE CHANCES FOR HAIL ARE NOT VERY GOOD EITHER. I HAVE PLACED LIKELY POPS IN NORTHEAST MISSOURI TONIGHT WITH CHANCE PROBABILITIES TAPERING OFF FURTHER SOUTH. THE STATIONARY FRONT AND OUTFLOW BOUNDARIES FROM TONIGHTS ACTIVITY SHOULD PROVIDE SOME SORT OF FOCUS FOR ADDITIONAL ACTIVITY TOMORROW AND TOMORROW NIGHT AND POSSIBLY ON WEDNESDAY IN THE NORTHEASTERN PORTIONS OF OUR FORECAST AREA. SIGNIFICANT RAINFALL IS MUCH NEEDED. DUE TO THE SLOW MOVEMENT OF THESE STORMS LOCAL SPOTS COULD RECEIVE SOME HEAVY RAINFALL WITH LESSER AMOUNTS OVER MOST OF THE REST OF THE AREA...ESPECIALLY NORTH OF INTERSTATE 70. CLOUDS WILL INCREASE AND THEREFORE THIS SHOULD PROVIDE A BRIEF RESPITE FROM THE HOT WEATHER WITH HIGHS IN THE MIDDLE 80S NORTH TO LOWER 90S IN RAINFREE AREAS. IN THE LONGER RANGE...THE MODELS STILL POINT TO UNSEASONABLY STRONG AMPLIFICATION OF THE JET STREAM PATTERN. THE BROAD UPPER RIDGE NOW CENTERED NEAR 90 DEGREES WEST MAY BRIEFLY RETROGRADE A BIT TOWARD THE PLAINS WITH AN UNUSUALLY DEEP TROUGH OVER THE EASTERN U.S. AND ANOTHER LONG WAVE TROUGH OVER THE WESTERN U.S. AS USUAL THIS MAKES FOR A VERY UNPREDICTABLE PATTERN FOR THE BISTATE AREA BUT IN GENERAL SOME COOLING AND SCATTERED SHOWERS AND THUNDERSTORMS WILL BE THE RULE...THE MODELS HAVE BEEN VERY UNPREDICTABLE AS TO TIMING AND STRENGTH SO WITH LOWER CONFIDENCE I HAVE INCLUDED LOW CHANCE PROBABILITIES OF PRECIPITATION. PEDIGO && .AVIATION... FOR THE 18Z TAFS... COLD FRONT OVER CENTRAL MO AS OF 17Z. SCATTERED RWS AND TRWS NORTH OF THE FRONT WL CONTINUE TO DISSIPATE THROUGH 20Z...MAY NEED TO STILL MENTION FOR AN HOUR OR TWO FOR KUIN...WILL WAIT TIL CLOSER TO TAF ISSUANCE TIME TO DECIDE. AS FOR REST OF TIME PERIOD...WILL SEE REDEVELOPMENT OF ACTIVITY LATER TONIGHT...AFTER 06Z...WITH POSSIBLE MCS DEVELOPMENT OVER IOWA THEN SINK SOUTHEASTWARD INTO KUIN...KSUS AND KSTL. OTHERWISE...VFR/MVFR CONDS THRU THE PERIOD. BYRD && .LSX WATCHES/WARNINGS/ADVISORIES... MO...NONE. IL...NONE. && WFO LSX

PRIMARILY DURING THE AFTERNOON AND EARLY EVENING HOURS EACH DAY... AS THE OLD FRONTAL BOUNDARY LINGERS ACROSS THE AREA AND WILL INTERSECT A MOIST AND UNSTABLE ATMOSPHERE.
