NWS Springfield, MO wrote its last area forecast discussion before the first event at Jun 19, 7:31 PM CST, 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 831 PM CDT FRI JUN 19 2009 ...MESOSCALE CONVECTIVE DISCUSSION... .UPDATE... ISOLATED THUNDERSTORMS WERE DEVELOPING THIS EVENING FROM SOUTHEAST KANSAS INTO CENTRAL MISSOURI. THE STORMS WERE DEVELOPING WELL AHEAD OF A WEAK FRONT ACROSS NORTHERN MISSOURI AND WITHIN A RIBBON OF BEST SURFACE MIXED LAYER CAPE NEAR 3000 J/KG...AND ALONG A MID LEVEL VORTICITY AXIS. IN ADDITION...DEEP LAYER SHEAR NEAR 45 KTS WAS SUFFICIENT TO PROMOTE ORGANIZATION AND PERHAPS A FEW SUPERCELLS. THE STORMS MAY GRADUALLY INCREASE IN COVERAGE AND INTENSITY THE REMAINDER OF THE EVENING WITH THE AID OF A DEVELOPING LOW LEVEL JET. A WEAK FRONT EXTENDED FROM NORTHEAST MISSOURI TO SOUTH CENTRAL KANSAS THIS EVENING. THIS FRONT HAD NEARLY STALLED ON THE PERIPHERY OF THE UPPER LEVEL RIDGE CENTERED OVER THE DEEP SOUTH. THE SPRINGFIELD 00Z SOUNDING SHOWED THAT MID LEVEL TEMPERATURES CONTINUED TO WARM WHICH WILL BE AN INHIBITING FACTOR TO THUNDERSTORM DEVELOPMENT ACROSS FAR SOUTHERN MISSOURI. A FEATURE OF INTEREST WAS A SMALL DISTURBANCE RIDING AROUND THE RIDGE ACROSS WESTERN OKLAHOMA. THIS FEATURE ALONG WITH A DEVELOPING LOW LEVEL JET WILL LIKELY BE ENOUGH TO SPARK ISOLATED TO SCATTERED STORMS THROUGH THE NIGHT FROM EASTERN KANSAS INTO CENTRAL MISSOURI. THERE WILL BE A LOW RISK OF SEVERE STORMS WITH ANY DEVELOPMENT THAT TAKES PLACE. FOSTER && .DISCUSSION... MAIN FOCUS IN THE SHORT TERM WILL BE WITH THUNDERSTORM CHANCES THIS EVENING/OVERNIGHT AND THEN BACK TO TEMPERATURES REST OF THE SHORT TERM INTO THE EXTENDED. CURRENTLY UPPER TROUGH PUSHING ACROSS THE NORTHERN/CENTRAL PLAINS WHILE A SURFACE COLD FRONT EXTENDS SOUTHEAST FROM SOUTHWEST IOWA INTO SOUTHWEST KANSAS. SOME ELEVATED SCATTERED STORMS AFFECTED BOURBON COUNTY EARLIER THIS MORNING AS AN EMBEDDED SHORTWAVE LIFTED NORTHEAST ACROSS EASTERN KANSAS. SURFACE BASED CAPES OF 2500 TO 3000 J/KG OCCURRING OVER CWA SO FAR THIS AFTERNOON WITH TEMPERATURES IN THE UPPER 80S TO LOW 90S. DEW POINTS WERE IN THE MID 60S ON THE PLATEAU AND LOW TO MID 70S IN SURROUNDING AREAS. SURFACE FRONT WILL BE THE MAIN FOCUS FOR CONVECTION IN OUR CWA TONIGHT. QUESTION IS HOW FAR SOUTH WILL THE FRONT MAKE IT. UPPER FLOW NOT EXPECTED TO HELP FRONT MAKE IT TOO FAR SOUTH OF THE I-70 CORRIDOR AND SO WOULD EXPECT MAIN CONVECTIVE ACTIVITY TO REMAIN NORTH OF THE CWA INTO OUR FAR NORTHERN COUNTIES. ANOTHER FLY IN OINTMENT WOULD BE MESOSCALE VORT DOWN IN TEXAS ATTM. GFS BRINGS THIS INTO THE AREA LATE TONIGHT AND COULD BE ADDITIONAL FOCUS FOR CONVECTIVE DEVELOPMENT. ANY STORMS THAT WOULD DEVELOP COULD BECOME SEVERE WITH LARGE HAIL/DAMAGING WIND THE MAIN SEVERE THREATS. UPPER RIDGE WILL BEGIN TO BUILD BACK INTO THE REGION ON SATURDAY BUT MAY HAVE SOME REMNANT CONVECTION OVER CENTRAL MISSOURI DURING THE MORNING HOURS. ANY REMAINING SURFACE BOUNDARIES COULD SPARK ADDITIONAL AFTERNOON CONVECTION AS WELL SO HAVE LEFT SMALL POPS IN FOR THE DAY. TEMPERATURES WILL BEGIN TO HEAT BACK UP INTO THE 90S AS THE RIDGE STARTS BUILDING BACK INTO THE AREA LATE IN THE WEEKEND. FOR THE EXTENDED PERIOD (MON THROUGH FRI)... UPPER RIDGE IN CONTROL OVER THE MID AND LOWER MISSISSIPPI VALLEY REGION WITH THERMAL CAP EXPECTED TO BE IN PLACE OVER THE CWA AT THE ONSET OF THE EXTENDED PERIOD. ENERGY FROM THE WESTERN TROUGH WILL LIFT NORTHEAST INTO THE NORTHERN HIGH PLAINS AND SOUTHERN CANADA BY MIDWEEK ALLOWING FOR RIDGE TO BEGIN RETROGRADING WESTWARD. SURFACE FRONT COULD DROP SOUTHEAST INTO THE AREA BY THURSDAY. MAY NEED TO INTRODUCE POPS BY THURSDAY/THURSDAY NIGHT IF MODELS CONTINUE ON THIS PATH. LINDENBERG && .AVIATION... VFR CONDITIONS ARE EXPECTED AT THE JOPLIN AND SPRINGFIELD TERMINALS THROUGH SATURDAY. A FEW STORMS MAY DEVELOP MAINLY NORTH OF THE TERMINAL SITES TONIGHT ALONG A FRONT THAT WILL STALL ACROSS CENTRAL MISSOURI. LOW LEVEL WIND SHEAR WILL AGAIN DEVELOP OVERNIGHT. GUSTY SOUTH WINDS WILL AGAIN DEVELOP AT THE SURFACE ON SATURDAY. FOSTER && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
