NWS Springfield, MO wrote its last area forecast discussion before the first event at May 1, 7:33 PM CST, 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 833 PM CDT THU MAY 1 2008 ...MESOSCALE CONVECTIVE DISCUSSION... .UPDATE... 0127Z... REPORTS OF LARGE HAIL TO THE SIZE OF TENNIS BALLS CONTINUE WITH THE STORMS IN SOUTHEAST KANSAS...ALONG WITH WALL CLOUDS AND BRIEF TORNADO TOUCHDOWNS. WILL BE ISSUING A TORNADO WARNING SHORTLY FOR THE NORTHWESTERN SECTIONS OF BOURBON COUNTY. WARNING WILL ALSO MENTION LARGE HAIL. DRY LINE WILL BEGIN TO RETROGRADE BACK TO THE WEST OVER THE NEXT COUPLE OF HOURS AND TORNADIC THREAT WILL DECREASE. MORE STORMS ARE EXPECTED OVERNIGHT AS COLD FRONT CATCHES UP TO DRY LINE AND STORMS FORM INTO MORE OF A LINEAR STRUCTURE. SQUALL LINE WITH EMBEDDED BOWS EXPECTED WITH LARGE HAIL...DAMAGING WIND AND STILL ISOLATED TORNADOES POSSIBLE AFTER MIDNIGHT. LINDENBERG && .DISCUSSION... A DRYLINE ASSOCIATED WITH AN APPROACHING STORM SYSTEM SURGED INTO KANSAS FLINT HILLS THIS AFTERNOON. THIS FEATURE WILL BE MONITORED CLOSELY OVER THE NEXT 6-8 HOURS FOR A LOW END CHANCE OF THUNDERSTORM DEVELOPMENT. MEANWHILE...A 110 KNOT UPPER SPEED MAX STILL RESIDES OVER THE SOUTHERN AND CENTRAL ROCKIES. THIS FEATURE WILL EVENTUALLY PROVIDE LIFT FOR EXPLOSIVE THUNDERSTORM DEVELOPMENT OVER KANSAS AND OKLAHOMA TONIGHT. THIS CLUSTER OF THUNDERSTORMS WILL BE THE MAIN SHOW FOR EXTREME SOUTHEAST KANSAS AND THE MISSOURI OZARKS TOWARD FRIDAY MORNING. SHORT TERM (TONIGHT - FRIDAY)... AS PREVIOUSLY MENTIONED...THE DRYLINE AT 1945Z CUTS ACROSS THE SOUTHERN FLINT HILLS EXTENDING FROM LAWRENCE KANSAS...TO PONCA CITY OKLAHOMA. AS ANTICIPATED BY SHORT TERM MODELS...EVIDENCE OF A DEVELOPING SURFACE LOW WAS INDICATED BY OBSERVATIONS OVER CENTRAL OKLAHOMA. THIS LOW WAS OCCURRING IN RESPONSE TO INCREASING DIFFLUENT FLOW ALOFT. MOISTURE CHANNEL IMAGERY DEPICTS THIS INCREASE IN DIFFLUENCE OVER THE SOUTHERN HIGH PLAINS. THE POPULAR QUESTION FOR THIS AFTERNOON REGARDS WHETHER OR NOT DISCRETE SUPERCELLS WILL DEVELOP ALONG THE DRYLINE PRIOR TO SUNSET. MY GUESS IS NO...UNLESS IT OCCURS UP IN NW MISSOURI OR FAR NE KANSAS. THE AIRMASS OVER EASTERN KANSAS AND OKLAHOMA HAS TOO GREAT OF A DESERT INFLUENCE...CREATING A VERY STRONG CAP. AS A MATTER OF FACT...19Z RUC ANALYSIS OF MEAN LAYER INHIBITION SUGGESTS THAT VALUES OVER FLINT HILLS RANGE FROM 150 - 350 J/KG. DESPITE SOME ADDITIONAL LIFT OCCURRING AS THE SOUTHERN PLAINS DIFFLUENCE INTERSECTS THE DRYLINE LATE THIS AFTERNOON...ALONG WITH ENHANCED LOW LEVEL CONVERGENCE NEAR SEDAN/FREDONIA KS FROM A DEVELOPING SURFACE LOW OVER OKLAHOMA...I DOUBT THAT THESE LIFTING MECHANISMS WILL BECOME STRONG ENOUGH TO PENETRATE UPDRAFTS THROUGH THE CAP. BOTH THE WRF AND RUC SHOW STORM INITIATION NEAR SUDAN OR FREDONIA KANSAS BY 00Z-03Z...HOWEVER...BOTH MODELS CONTINUE TO OVERESTIMATE MOISTURE LEVELS. THIS OVERESTIMATION FALSELY WEAKENS THE CAP. THIS IS ESPECIALLY EVIDENT IN THE RUC...WHICH SUGGESTS AN AXIS OF 69-70 DEWPOINTS ALONG THE DRYLINE. MORE REALISTICALLY PER LOCAL OBS...DEW POINT MEASUREMENTS ARE ONLY AROUND 58-62 DEGREES. WHAT WILL BREAK THE CAP IS THE APPROACH OF A 110 KNOT SPEED MAX WITHIN THE JET STREAM...ALONG WITH MASS CONVERGENCE IN RESPONSE TO AN INCREASING LOW LEVEL JET OVER EASTERN OKLAHOMA. THIS ADDITIONAL FORCING WILL OCCUR AT AROUND 03-05Z TONIGHT...IGNITING A CLUSTER OR SQUALL LINE OF THUNDERSTORMS OVER NORTHERN OKLAHOMA AND EASTERN KANSAS. THESE STORMS WILL TRACK INTO EXTREME SOUTHEAST KANSAS AND WESTERN MISSOURI AFTER MIDNIGHT. AREAS ALONG AND WEST OF A LINE FROM CASSVILLE TO OSCEOLA WILL SUSTAIN THE GREATEST CHANCES OF EXPERIENCING THIS ACTIVITY PRIOR TO 6AM. DUE TO EXTREME WIND SHEAR IN TONIGHTS ENVIRONMENT...LARGE HAIL UP TO THE SIZE OF GOLF BALLS...AND DAMAGING WINDS IN EXCESS OF 70 MPH WILL OCCUR NEAR THE STRONGEST UPDRAFTS. SQUALL LINE TORNADOES CAN NOT BE RULED OUT ALONG THE LEADING EDGE OF THE SQUALL. MODELS STILL INDICATE THAT AREAS ALONG AND EAST OF HIGHWAY 65 WILL REMAIN WITHIN THE WARM SECTOR HEADING INTO FRIDAYS DAY PERIOD. THERE MAY BE A BRIEF WINDOW OF OPPORTUNITY FOR UPDRAFTS TO BECOME MORE DISCRETE IN NATURE OVER THE EASTERN OZARKS. 0-6KM SHEAR VECTORS ASSUME AN ORIENTATION THATS MORE FAVORABLE FOR DISCRETE CELLS BY 12-15Z. THIS STILL REMAINS A SHORT TERM FORECAST CHALLENGE...AND DEPENDS ON TWO VARIABLES. ONE...HOW WILL TONIGHT/FRIDAY MORNINGS CONVECTION AND CLOUD COVER DISTORT INSTABILITY LEVELS. AND TWO...WILL THE COLD FRONT BECOME PROGRESSIVE ENOUGH TO SHIFT EAST OF THE OZARKS PRIOR TO ADDITIONAL DEVELOPMENT OF POSSIBLE DIURNAL INSTABILITY. AT ANY RATE...ALL PRECIPITATION SHOULD SHIFT EAST OF THE OZARKS BY FRIDAY MID AFTERNOON...SETTING UP A COOLER BUT DRY FORECAST FOR FRIDAY EVENING AND OVERNIGHT. LONG TERM (SATURDAY - WEDNESDAY)... SEASONAL AND DRY CONDITIONS ARE STILL EXPECTED FOR THE WEEKEND AND EARLY NEXT WEEK. FLOW BECOMES NORTHWESTERLY IN THE WAKE OF TONIGHTS SYSTEM...AS HIGH PRESSURE AT THE SURFACE INCREASES. RAIN CHANCES ENTER THE FORECAST BY TUESDAY...AS MEDIUM RANGE MODELS SUGGEST THAT AN UPPER LEVEL TROUGH DIGS INTO THE WESTERN CONUS. THIS WILL CREATE A PATTERN FAVORABLE FOR MOISTURE TO RETURN. CRAMER && .AVIATION... FOR THE 00Z TAFS...EXPECTING VFR CEILINGS TO PERSIST UNTIL OVERNIGHT WHEN THE SQUALL LINE OF STORMS IS EXPECTED TO AFFECT THE TERMINAL LOCATIONS. WILL CONTINUE LOW LEVEL WIND SHEAR THIS EVENING AND OVERNIGHT WITH 2000 FOOT WINDS OF 45 TO 50 KTS EXPECTED. MVFR CEILINGS EXPECTED WITH THUNDERSTORMS OVERNIGHT. SURFACE WINDS OF 15 TO 30 KTS POSSIBLE. LINDENBERG && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&

WEATHER HAZARDS EXPECTED: THUNDERSTORMS CAPABLE OF PRODUCING HAIL TO THE SIZE OF GOLF BALLS...WINDS IN EXCESS OF 70 MPH AND ISOLATED TORNADOES. AREAS AFFECTED AND TIMING: THUNDERSTORMS WILL CONTINUE TO FORM JUST AHEAD OF A DRY LINE IN EASTERN KANSAS THIS EVENING AND PUSH OFF TO THE NORTHEAST. THESE STORMS WILL LIKELY EFFECT SOUTHEAST KANSAS AND WESTERN MISSOURI THROUGH THE EVENING HOURS. DISCUSSION: THUNDERSTORMS HAVE QUICKLY DEVELOPED JUST AHEAD OF A DRY LINE EXTENDING FROM CENTRAL SOUTHEAST KANSAS INTO CENTRAL IOWA THIS EVENING. THESE STORMS WILL TRACK OFF TO THE NORTHEAST THIS EVENING. THE DRY LINE WILL CONTINUE TO TRACK TO THE EAST EARLY THIS EVENING...BUT ONCE THE SUN SETS...THE DRY LINE SHOULD STALL IF NOT EVEN MOVE BACK TO THE WEST. THE THUNDERSTORMS THAT FORM AHEAD OF THE DRY LING WILL LIKELY MOVE INTO THE EXTREME WESTERN PORTIONS OF THE OUTLOOK AREA THIS EVENING. VERY LARGE HAIL WILL BE POSSIBLE WITH ANY STORMS THAT DEVELOP...ALONG WITH DAMAGING WINDS AND EVENING ISOLATED TORNADOES. OVERNIGHT A COLD FRONT WILL PUSH TO THE EAST WITH A CLUSTER OF STRONG TO SEVERE THUNDERSTORMS DEVELOPING ALONG THE FRONT. THESE STORMS WILL IMPACT EXTREME SOUTHEAST KANSAS AND FAR WESTERN MISSOURI AFTER MIDNIGHT TONIGHT. LOCATIONS ALONG AND WEST OF A LINE FROM OSCEOLA TO CASSVILLE WILL SUSTAIN THE BEST CHANCES FOR EXPERIENCING THESE INTENSE STORMS PRIOR TO 6 AM. DAMAGING WIND GUSTS IN EXCESS OF 70 MPH AND HAIL TO THE SIZE OF GOLF BALLS WILL BE ASSOCIATED WITH THE STRONGEST UPDRAFTS. THESE STORMS ARE EXPECTED TO BE IN THE FORM OF A SQUALL LINE. DUE TO EXTREME WIND SHEAR IN TONIGHTS STORM ENVIRONMENT...SQUALL LINE TORNADO DEVELOPMENT ALONG THE LEADING EDGE OF THE LINE CAN NOT BE RULED OUT. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY. STRONG TO SEVERE THUNDERSTORMS WILL BE ONGOING FIRST THING FRIDAY MORNING IN THE VICINITY OF THE HIGHWAY 65 CORRIDOR. STRONG WIND FIELDS ALOFT AND AN UNSTABLE ATMOSPHERE WILL CONTINUE TO SUPPORT A LINE OF SEVERE THUNDERSTORMS ALONG AND AHEAD OF THE COLD FRONT. DAMAGING WIND GUSTS IN EXCESS OF 70 MPH AND LARGE HAIL WILL CONTINUE TO BE THE PRIMARY SEVERE WEATHER RISKS. AS THE DAY PROGRESSES...THE COLD FRONT WILL MOVE WEST TO EAST ACROSS THE OUTLOOK AREA. GIVEN THE EXPECTED WIND SHEAR AND INSTABILITY PROFILES ACROSS THE EASTERN OZARKS...IT IS POSSIBLE FOR THIS LINE OF STORMS TO BREAK UP INTO SEGMENTS OR EVEN SUPERCELL THUNDERSTORMS. IF THIS OCCURS...THE RISK FOR TORNADOES WILL INCREASE. PERSONS EAST OF THE HIGHWAY 65 CORRIDOR ARE URGED TO MONITOR THE LATEST FORECASTS REGARDING THE SEVERE WEATHER POTENTIAL FRIDAY. THUNDERSTORMS WILL EXIT THE OUTLOOK AREA LATE FRIDAY AFTERNOON. ANOTHER STORM SYSTEM MAY MOVE INTO THE REGION TUESDAY AND WEDNESDAY BRINGING ANOTHER CHANCE FOR THUNDERSTORMS. .SPOTTER INFORMATION STATEMENT...
