NWS Springfield, MO wrote its last area forecast discussion before the first event at Apr 2, 5:11 PM CST, 5 hours 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 611 PM CDT FRI APR 2 2010 ...UPDATE TO AVIATION... .DISCUSSION... NEAR TERM FCST CHALLENGES INVOLVE EVOLUTION OF CONVECTION THROUGH TONIGHT...THEN TIMING AND EXTENT OF ANY FURTHER RAIN CHANCES THROUGH THE FORECAST PERIOD (THROUGH FRI). COLD FRONT/TROUGH EXTENDS FROM IA/NEB BORDER SOUTH INTO EASTERN KS. OUTFLOW FROM EARLY MORNING CONVECTION HAS ALSO MOVED EAST FROM CNTRL MO INTO THE WESTERN MO OZARK HIGHLANDS..JUST PASSING THROUGH KSGF BETWEEN 1715Z-1730Z. LINE/BAND OF CONVECTION FROM MO SOUTH INTO FAR NE TX ALONG THE FRONT IS GENERALLY WEAK WITH THE NEAR TERM BEST POTENTIAL FOR STRENGTHENING ALONG THE SOUTHERN FLANK OF THE CONVECTION WHERE BETTER INSTABILITY EXISTS. 18Z KSGF SOUNDING SHOWING A MIXED BAG SINCE PRECIP WAS FALLING AT THE TIME OF THE SOUNDING. NOT SURE HOW MUCH OF THE COOLING WAS DUE TO PRECIP...BUT IN GENERAL THE SOUNDING CONFIRMS THE MODEL TREND OF WEAKENING THE EML. AS UPPER TROUGHING APPROACHES FROM THE WEST...COOLING MID LEVEL TEMPERATURES SHOULD CONTINUE TO ERODE CAPPING OVER THE EASTERN CWFA...THEN AT THAT POINT ITS JUST A MATTER OF HOW MUCH LOW LEVEL MOISTURE AND RESULTANT MIXED LAYER INSTABILITY WE CAN GET FAR ENOUGH NORTH INTO MO TO WORK WITH VERY STRONG VERTICAL SHEAR PROFILES. 18Z LITTLE ROCK AR SOUNDING DRIER THEN NAM/WRF PROGGED SOUNDING FOR THE SAME TIME...SO BELIEVE BUFR NAM SOUNDINGS FOR SOUTHERN MO ARE A LITTLE OVERDONE ON THE AMOUNT OF INSTABILITY THAT WILL BE IN PLACE AS THE CONVECTION MOVES EAST INTO MO. HOWEVER...THERE MAY BE SLIGHTLY BETTER MOISTURE AVAILABILITY CLOSER TO THE FRONT. SO...STILL EXPECT SOME INTENSIFICATION OF TSTMS OVER SOUTHERN MO LATE THIS AFTERNOON EARLY THIS EVENING. HOWEVER...EVEN JUST 500 J/KG MLCAPE COMBINED WITH VERY STRONG DEEP LAYER SHEAR SHOULD SUPPORT STORM ORGANIZATION ALONG THE FRONT WITH EMBEDDED ISOLD SUPERCELL STRUCTURES AND BOWING SEGMENTS. SOME INITIAL DEVELOPMENT WILL BE POSSIBLE ON THE OUTFLOW BOUNDARY...AND ALSO ALONG THE SYNOPTIC SCALE FRONT/TROUGH. MOST OF THE CONVECTION SHOULD BE THROUGH THE REGION BY 06Z. DAMAGING WIND IS THE MAIN THREAT...BUT MUST CONSIDER THE SMALL RISK OF TORNADOES GIVEN THE STRONG LOW LEVEL SHEAR/HELICITY FIELDS. BEYOND TONIGHT...QUICK ZONAL SW-NE ZONAL UPPER PATTERN WILL BE IN PLACE THROUGH EARLY NEXT WEAK. HAVE BUMPED UP POPS FOR SUNDAY NIGHT-MON MORNING OVER THE NORTHERN CWFA WITH SFC BOUNDARY SLIPPING SOUTH AND INCREASING LIFT NORTH OF THE FRONT AS LOW LEVEL SOUTH FLOW INCREASES. THIS FRONT LIFTS BACK TO THE NORTH AS GUSTY SOUTH WINDS BECOME REESTABLISHED OVER THE REGION MON-TUE. A MORE SUBSTANTIAL FRONT WILL MOVE INTO THE REGION LATE TUE-EARLY WED AS A STRONGER UPPER TROUGH MOVES FROM THE PLAINS INTO THE UPPER MIDWEST. DSA && .AVIATION... FOR THE 00Z TAFS...CONVECTION SHIFTING EAST OF THE FORECAST POINTS WITH SGF/BBG ON THE WESTERN EDGE OF THE RAIN. WILL CONTINUE RAIN FOR A FEW HOURS AT THE ONSET WITH GENERALLY VFR CEILINGS EXPECTED. WINDS WILL SHIFT TO THE WEST AND THEN NORTHWEST OVERNIGHT WITH THE FRONTAL PASSAGE...BEFORE BACKING TO THE SOUTHWEST ON SATURDAY AFTERNOON. LINDENBERG && .SGF WATCHES/WARNINGS/ADVISORIES...
