NWS Springfield, MO wrote its last area forecast discussion before the first event at May 9, 5:26 PM CST, 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 626 PM CDT TUE MAY 9 2006 ...SEVERE WEATHER UPDATE... .UPDATE... THUNDERSTORMS HAVE DEVELOPED ACROSS FAR SOUTHERN MISSOURI ALONG A RESIDUAL OUTFLOW BOUNDARY. AN INTENSE THUNDERSTORM WAS TRACKING ACROSS OZARK INTO HOWELL COUNTIES AT 625 PM. BACKGROUND HELICITIES WERE AROUND 100 M2/S2 BUT HAVE TRENDED UPWARD THE PAST COUPLE OF HOURS. ALTHOUGH THE TORNADO POTENTIAL ACROSS FAR SOUTH CENTRAL MISSOURI APPEARS LOW IT CANNOT BE RULED OUT. AT THE VERY LEAST... AMPLE DEEP LAYERED SHEAR IS IN PLACE TO SUPPORT ROTATING UPDRAFTS WITH POTENTIAL OF VERY LARGE HAIL ACROSS FAR SOUTH CENTRAL MISSOURI. INTENSE RAINFALL RATES AND WET GROUND CONDITIONS WILL PROMOTE SOME LOCALIZED FLOODING. THE BOUNDARY AND ASSOCIATED CONVECTION WILL SAG SOUTH INTO NORTHERN ARKANSAS THIS EVENING WITH A TEMPORARY BREAK FROM THUNDERSTORMS ACROSS SOUTHERN MISSOURI. ANOTHER ROUND OF THUNDERSTORMS AND HEAVY RAINFALL WILL DEVELOP BY WEDNESDAY MORNING AS THE NEXT SIGNIFICANT SHORTWAVE SWEEPS INTO THE REGION. FOSTER && .DISCUSSION... OUTFLOW BOUNDARY LEFT OVER FROM EARLY MORNING STORMS HAS DRIFTED SOUTHWARD AND CURRENTLY EXTENDS FROM NEOSHO TO NIXA TO HOUSTON. EARLIER BREAKS IN CLOUD COVER ALLOWED THE AREA TO HEAT INTO THE MID TO UPPER 70S WITH DEWPOINT TEMPERATURES RECOVERING INTO THE MID 60S OVER MUCH OF THE REGION. CAPPING INVERSION IS GONE AND NOW WE ARE PRETTY MUCH IN A WAIT AND SEE WHERE IT GOES MODE. LATEST RADAR SHOWS A FEW ECHOES BUBBLING OVER EASTERN NEWTON COUNTY SO WE WILL CONTINUE TO WATCH THIS AREA CLOSELY. MAIN COLD FRONT HAS MADE SOME SOUTHWARD PROGRESS...AND EXTENDS ROUGHLY FROM COLUMBIA TO CHANUTE. THE CONVERGENCE ALONG THE FRONT COMBINED WITH DISTURBED UPPER FLOW WILL KEEP PRECIP CHANCES GOING THROUGH THE NIGHT AND INTO WEDNESDAY MORNING. PRECIPITABLE WATER REMAINS WELL ABOVE AN INCH...AND WITH THE ALREADY HEAVY RAINFALL RECEIVED EARLIER TODAY AND POTENTIAL FOR MORE RAIN THROUGH TONIGHT...A FLOOD WATCH WILL BE POSTED FOR ABOUT THE SOUTHERN 2/3RDS OF THE FORECAST AREA. OVER THE NEXT FEW DAYS...THE MAIN UPPER TROUGH WILL TRACK ACROSS THE NORTHERN PLAINS BEFORE CUTTING OFF AND STALLING OVER NORTHERN INDIANA. THERE IS STILL A CHANCE FOR GLANCING LIGHT PRECIP OVER CENTRAL MISSOURI IF CYCLONIC CIRCULATION BECOMES BROAD ENOUGH. HOWEVER FOR NOW WILL CONTINUE WITH A DRY FORECAST THROUGH SATURDAY AS NORTHERLY SURFACE FLOW ADVECTS A DRY AND COOL AIRMASS OVER THE REGION. IN THE EXTENDED....MAINTAINED LOW CHANCES FOR SHOWERS/STORMS FROM SATURDAY NIGHT THROUGH SUNDAY NIGHT AS UPPER LOW MEANDERS WESTWARD INTO EASTERN ILLINOIS AND WESTERN/CENTRAL KENTUCKY. OTHERWISE WILL KEEP TEMPERATURES ON THE COOL SIDE AS UPPER LOW HELPS SPREAD CANADIAN AIR INTO THE CENTRAL U.S. THROUGH EARLY NEXT WEEK. TERRY && .AVIATION... FOR THE 00Z TAFS...STORMS FORMING ALONG BOUNDARY TO THE SOUTH OF THE KSGF AND KJLN TERMINALS SHOULD REMAIN TO THE SOUTH DURING THE EVENING HOURS. WILL KEEP VFR CONDITIONS IN TIL AFTER MIDNIGHT. UPPER LEVEL SYSTEM NOW MOVING INTO THE SOUTHERN PLAINS WILL PUSH CONVECTION NOW OVER TEXAS PANHANDLE INTO THE AREA. EXPECT MVFR TO IFR CONDITIONS AS CONVECTION AND TRAILING STRATIFORM RAIN MOVES THROUGH THE AREA. CONDITIONS EXPECTED TO IMPROVE TO VFR AFTER 18Z WITH THE PASSAGE OF THE SURFACE FRONT. GAEDE && .HYDROLOGY... THE OZARKS AND SOUTHEAST KANSAS HAVE HAD NEARLY 150-200% ABOVE NORMAL RAINFALL SINCE APRIL 25TH. ANY ADDITIONAL HEAVY RAINFALL WILL CREATE FLOODING PROBLEMS ACROSS THE REGION. THEREFORE...A FLOOD WATCH HAS BEEN ISSUED FOR OVERNIGHT. FLASH FLOOD GUIDANCE VALUES RECENTLY HAVE DECREASE TO LESS THAN ONE INCH (HOURLY VALUES) FOR A GOOD PART OF THE OZARKS AND SOUTHEAST KANSAS. WITH 3/6 HOUR FLASH FLOOD GUIDANCE VALUES BETWEEN 1.5 TO 3.0 INCHES. WITH THE AMOUNT OF RAINFALL EXPECTED OVERNIGHT...FLOODING IS A GOOD POSSIBILITY. EVEN RIVER FLOODING MAY BECOME A PROBLEM IF WE GET AMOUNTS EXCEEDING THREE INCHES OVERNIGHT. JLT .SGF WATCHES/WARNINGS/ADVISORIES... MO...AREAS SOUTH OF A NEVADA TO OSAGE BEACH TO VIENNA LINE FROM 6 PM TO 6 AM. KS...CHEROKEE AND CRAWFORD COUNTY FROM 6 PM TO 6 AM. WFO SGF
