NWS Springfield, MO wrote its last area forecast discussion before the first event at Jul 18, 5:18 PM CST, 3 hours 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 618 PM CDT TUE JUL 18 2006 ...UPDATED AVIATION DISCUSSION... .UPDATE... A WEAK SURFACE TROUGH/AXIS OF CONVERGENCE STRETCHES FROM A WEAK SURFACE LOW JUST SOUTH OF STL WESTWARD INTO NORTHEASTERN PORTIONS OF OUR CWA. CUMULUS/MODEST TOWERING CUMULUS FIELD EXTENDS WESTWARD ALONG THIS BOUNDARY INTO OUR CWA. STRONGEST MOISTURE CONVERGENCE HAS BEEN NEAR THE SURFACE LOW AROUND STL VICINITY WHERE AFTER REPEATED ATTEMPTS AN INTENSE UPDRAFT WAS ABLE TO MAINTAIN ITSELF. THUS FAR THE MOISTURE CONVERGENCE IN OUR CWA HAS NOT BEEN SUFFICIENT TO SUPPORT SUSTAINED UPDRAFTS...HOWEVER ATMOSPHERE REMAINS EXPLOSIVELY UNSTABLE (MLCAPES 4000+ J/KG) AND 30KT OF MID LEVEL FLOW WOULD BE SUFFICIENT FOR ORGANIZED CONVECTION/SUPERCELLS GIVEN THE EXTREME INSTABILITY. WILL CONTINUE TO MONITOR RADAR/SATELLITE TRENDS FOR POSSIBLE CONVECTIVE INITIATION OVER OUR CWA THIS EVENING. IZZI && .DISCUSSION...//ISSUED AT 240 PM CDT TUE JUL 18 2006// TEMPERATURES HAD AGAIN SOARED INTO THE MIDDLE AND UPPER 90S ACROSS MUCH OF THE FORECAST AREA EARLY THIS AFTERNOON WITH HEAT INDICES BETWEEN 100 AND 107. THESE TEMPERATURES COUPLED WITH DEWPOINTS NEAR 70 WERE YIELDING SURFACE BASED CAPES AROUND 4000 J/KG. HOWEVER A CAPPING INVERSION AND LACK OF LOW LEVEL CONVERGENCE HAS INHIBITED CONVECTIVE DEVELOPMENT SO FAR. WATER VAPOR IMAGERY AND PROFILERS CLEARLY DEPICT THE UPPER RIDGE AXIS WITH 596 HEIGHTS EXTENDING FROM THE SOUTHERN ROCKIES INTO MISSOURI. THE HEAT WAVE WILL PERSIST INTO THURSDAY AS THE UPPER RIDGE REMAINS ANCHORED ACROSS THE REGION. 850 MB TEMPERATURES AROUND 25 DEGREES C AND 700 MB TEMPERATURES AROUND 13 DEGREES C UNDERNEATH THE UPPER HIGH WILL PUSH AFTERNOON HIGHS TO AROUND 100 ACROSS MUCH OF THE FORECAST AREA FOR A COUPLE OF MORE DAYS. WITH THE CONTINUATION OF THE OPPRESSIVE HEAT...THE EXCESSIVE HEAT WARNING WAS EXPANDED TO INCLUDE MOST OF THE FORECAST AREA. A HEAT ADVISORY WILL BE ISSUED FOR FAR SOUTH CENTRAL MISSOURI. DESPITE ANY SIGNIFICANT FORCING...AN ISOLATED THUNDERSTORM CANNOT BE RULED LATE THIS AFTERNOON AND EVENING GIVEN THE VERY UNSTABLE AIRMASS. SOME QUESTION TO WHETHER THE CAPPING INVERSION CAN BE BROKEN...BUT IF CONVECTION DOES FORM IT COULD QUICKLY BECOME SEVERE. THE BEST CHANCE CONVECTIVE DEVELOPMENT WILL STRETCH FROM CENTRAL MISSOURI TO THE EASTERN OZARKS WHERE MOISTURE IS POOLING ALONG A WEAK BOUNDARY. THE UPPER PATTERN WILL BE BEGIN TO TRANSITION LATE IN THE WEEK WITH THE UPPER RIDGE AXIS RETROGRADING TO THE WEST. THIS WILL ALLOW SHORTWAVES TO SLIDE INTO THE REGION WITH AN ASSOCIATED FRONT SAGGING SOUTHWARD. PREFER THE SLOWER WRF MODEL ON THE FRONTAL PROGRESSION GIVEN THE STRONG RIDGE IN PLACE NOW. HOWEVER GIVEN THE UNCERTAINTY I WILL NOT EXTEND THE HEAT WARNING INTO FRIDAY YET. IF THE SLOWER FRONTAL MOVEMENT VERIFIES...TEMPERATURES WILL AGAIN REACH CRITICAL LEVELS. AN INCREASED CHANCE OF CONVECTION WILL ARRIVE THURSDAY NIGHT OR FRIDAY DEPENDING ON THE PROGRESSION OF THE FRONT. THE CHANCE OF RAIN WILL CONTINUE INTO SATURDAY. TEMPERATURES WILL ALSO COOL BACK DOWN TOWARD NORMAL LEVELS THIS WEEKEND. FOSTER && .AVIATION... FOR THE 00Z TAFS...ANY ISOLATED CONVECTION THIS EVENING SHOULD REMAIN NORTH OF BOTH TERMINALS WITH MAINLY CLEAR SKIES EXPECTED. LIGHT AND VARIABLE WINDS WILL BECOME MORE SOUTHERLY THOUGH REMAIN FAIRLY LIGHT WEDNESDAY. IZZI && .CLIMATOLOGY... AFTERNOON TEMPERATURES AT SPRINGFIELD ROSE TO 99 DEGREES THIS AT 1 PM. THIS READING MAKES TODAY THE 5TH WARMEST JULY 18TH ON RECORD. HIGH TEMPERATURES ARE FORECAST TO BE NEAR 100 DEGREES FOR THE NEXT TWO DAYS. THIS WOULD PLACE THE HIGH TEMPERATURES FOR THE NEXT THREE DAYS INTO THE TEN WARMEST DAYS FOR THIS PERIOD IN JULY. IN ADDITION THE LOW TEMPERATURES AT NIGHT WILL BE IN THE TOP TEN WARMEST LOW TEMPERATURES AS WELL. HATCH && .SGF WATCHES/WARNINGS/ADVISORIES...
