NWS Springfield, MO wrote its last area forecast discussion before the first event at Aug 18, 1:48 AM CST, 9 hours 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 248 AM CDT SAT AUG 18 2007 .DISCUSSION... MAIN FORECAST FOCUS THROUGH MONDAY WILL BE ON POPS AS THE REMNANTS OF TROPICAL STORM ERIN IMPACT THE REGION. ATTENTION THEN TURNS TO TEMPERATURES TOWARDS THE MIDDLE OF NEXT WEEK AS AN UPPER LEVEL RIDGE BEGINS TO FIRM UP OVER THE SOUTHERN TIER OF STATES. TODAY...THE 00Z MODEL SUITE STRUGGLED WITH THEIR INITIALIZATIONS OVER EASTERN TEXAS IN THE UPPER LEVELS. WATER VAPOR IMAGERY AND PROFILERS IN THE ARKLATEX REGION INDICATE WHAT APPEARS TO BE A FAIRLY DECENT SHORT WAVE TROUGH SHIFTING NORTH TOWARDS THE OZARKS. MODELS SEEM TO HAVE A FAIR HANDLE ON THIS...INDICATING A VORTICITY LOBE SHIFTING NORTH TOWARDS SOUTHWEST MISSOURI BY EARLY THIS AFTERNOON. BY THIS TIME...LITTLE IN THE WAY OF CONVECTIVE INHIBITION IS EXPECTED WITH MLCAPES RANGING FROM ABOUT 1000 TO 1500 J/KG. WITH THE EXPECTED INCREASE IN LARGE SCALE ASCENT... SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP. THE BEST CHANCES FOR PRECIPITATION WILL BE ALONG AND WEST OF HIGHWAY 65 WHERE HIGH CHANCE TO LIKELY POPS WERE PLACED. THESE STORMS SHOULD BE EFFICIENT RAIN PRODUCERS WITH PRECIPITABLE WATER VALUES AROUND TWO INCHES AND WET BULB ZERO LEVELS FAIRLY HIGH. THE CLOUDS AND PRECIPITATION WILL YIELD COOLER TEMPERATURES THIS AFTERNOON WITH MOST AREAS TOPPING OUT IN THE LOWER 90S. TONIGHT AND SUNDAY...WILL SEE A DECREASE IN PRECIPITATION COVERAGE TONIGHT WITH THE OVERALL DECREASE IN INSTABILITY. BEST CHANCES FOR PRECIPITATION WILL BE OVER CENTRAL MISSOURI AHEAD OF THAT VORTICITY LOBE. MODELS INDICATE ANOTHER CHUNK OF ENERGY SHOOTING EAST ACROSS KANSAS AND NORTHERN MISSOURI ON SUNDAY. MORE SHOWER AND THUNDERSTORM DEVELOPMENT IS THEREFORE ANTICIPATED...WITH THE BEST CHANCES ACROSS CENTRAL MISSOURI CLOSER TO THE UPPER LEVEL ENERGY. WENT FAIRLY CLOSE TO MAV GUIDANCE FOR TEMPERATURES BOTH PERIODS WITH HIGHS ON SUNDAY ONCE AGAIN IN THE LOWER 90S. SUNDAY NIGHT AND MONDAY...AM STILL UNCLEAR AS TO THE TIMING AND PLACEMENT OF THE REMNANTS OF ERIN. NOT OUT OF THE QUESTION WE COULD SEE SOME LINGERING SHOWERS AND THUNDERSTORMS SOMEWHERE ACROSS THE OZARKS. HAVE KEPT SLIGHT CHANCE POPS GOING FOR THESE PERIODS AND WILL CONTINUE TO EVALUATE AS THE EVOLUTION OF THESE REMNANTS BECOMES CLEARER. DO THINK TEMPERATURES WILL WARM A FEW DEGREES OVER THOSE OF SUNDAY WITH LESS CLOUD COVER EXPECTED. MONDAY NIGHT INTO FRIDAY...A LARGE SCALE RIDGE WILL BUILD ACROSS THE SOUTHERN HALF OF THE COUNTRY THROUGH MIDWEEK. THE HIGHEST HEIGHTS WILL TEND TO SLOWLY SHIFT INTO THE SOUTHEAST UNITED STATES BY THE END OF NEXT WEEK AS HEIGHTS LOWER ACROSS THE WESTERN UNITED STATES. AM THEREFORE LOOKING FOR A DRY STRETCH OF WEATHER AROUND MIDWEEK WITH A CONTINUED WARMING TREND. WENT AT OR ABOVE MEX GUIDANCE FOR THE PERIOD WITH THE ECMWF SHOWING A WARMER SIGNAL THAN THAT OF THE GFS. WILL NEED TO WATCH POPS LATE NEXT WEEK AS LOWERING HEIGHTS MAY EVENTUALLY SPREAD INTO THE NORTHERN PLAINS AND GREAT LAKES...POSSIBLY SENDING A FRONT SOUTH TOWARDS THE OZARKS. SCHAUMANN && .AVIATION... INITIAL THOUGHTS FOR THE 12Z TAFS...WILL CONTINUE SOUTHEAST TO SOUTH SURFACE FLOW THROUGH THE FORECAST PERIOD AS SURFACE HIGH OVER THE GREAT LAKES REGION SHIFTS SOUTHEAST INTO THE OHIO VALLEY AND SURFACE TROUGH DEEPENS OVER THE PLAINS. WILL CARRY VICINITY STORMS FROM LATE MORNING THROUGH THE AFTERNOON WITH TEMPO THUNDER THROUGH EARLY/MID AFTERNOON AS PEAK HEATING DESTABILIZES INCREASINGLY MOIST AIRMASS OVER THE REGION. WILL KEEP VFR CEILINGS THROUGH THE FORECAST AS REMNANTS OF ERIN REMAIN OVER THE SOUTHERN PLAINS. TERRY && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
