NWS Kansas City, MO wrote its last area forecast discussion before the first event at Jun 15, 2:40 AM CST, 7 hours 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 340 AM CDT SUN JUN 15 2008 .DISCUSSION... ...POTENTIALLY SIGNIFICANT DAMAGING WIND EVENT POSSIBLE... CURRENT TRENDS AND MODEL GUIDANCE SEEM TO BE CONVERGING ON A POTENTIALLY SIGNIFICANT SEVERE WEATHER EPISODE FOR THIS AFTERNOON AND EVENING. REGIONAL RADAR MOSAIC SHOWING ONGOING MCS ACROSS CENTRAL AND EASTERN IOWA ATTM WITH ASSOCIATED OUTFLOW BOUNDARY SAGGING SOUTHWARD. SFC OBSERVATIONS REVEALING LLVL MOISTURE RETURNING IN EARNEST ACROSS THE SOUTHERN PLAINS WITH LOWER 70 DEWPOINTS APPROACHING THE KS/OK BORDER. LLVL AIR MASS WILL BECOME INCREASINGLY MOIST DURING THE DAY TODAY AS DEWPOINTS CLIMB INTO THE UPPER 60S TO LOWER 70S ACROSS THE FORECAST AREA BY MID AFTERNOON. MID LEVEL IMPULSE IS PROGGED TO PROGRESS FROM THE NORTHERN PLAINS INTO THE GREAT LAKES THROUGH THE DAY TODAY. AS THIS OCCURS...SFC BOUNDARY WILL PUSH SOUTHWARD AND INCH INTO NORTHWEST MISSOURI BY MID MORNING. DEEP MOIST CONVECTION SEEMS INCREASINGLY POSSIBLE BY MID TO LATE MORNING ALONG THE AFOREMENTIONED SFC BOUNDARY ACROSS NORTHEAST KANSAS/NORTHWEST MISSOURI WITH ADDITIONAL CONVECTION LIKELY BY MID AFTERNOON. AIR MASS ACROSS THE AREA WILL BECOME INCREASINGLY UNSTABLE AS LLVL ENVIRONMENT MOISTENS AS MID LEVEL COOLING OVERSPREADS THE AREA. THIS SHOULD YIELD STRONG TO EXTREME INSTABILITY BY MID AFTERNOON WITH MLCAPE VALUES IN THE 3000-4000+ J/KG RANGE. THIS WILL LEAD TO INTENSE UPDRAFT POTENTIAL AS STORMS BECOME MORE WIDESPREAD DURING THE AFTERNOON HOURS. IN ADDITION...MAGNITUDE OF DEEP LAYER SHEAR ALONG WITH VEERING WIND PROFILES SHOULD SUPPORT SUPERCELL STRUCTURES...AT LEAST WITH INITIAL CONVECTION THAT DEVELOPS. GIVEN STEEPENING LAPSE RATES AND HIGH INSTABILITY...INITIAL UPDRAFTS ASSOCIATED WITH CONVECTION WILL LIKELY RESULT IN LARGE HAIL...SOME POTENTIALLY VERY LARGE...ESPECIALLY ASSOCIATED WITH AFOREMENTIONED SUPERCELLS. TORNADO POTENTIAL SEEMS LESS OF A THREAT GIVEN ONLY MODEST LLVL FLOW EXPECTED. HOWEVER...ONE CANNOT IGNORE THE VEERING PROFILES EXPECTED BY MID-AFTERNOON WHICH SHOULD RESULT IN SOMEWHAT ENLARGED HODOGRAPHS. THIS ALONG WITH 0-3KM CAPE VALUES APPROACHING 200 J/KG AND NEARLY DRY ADIABATIC LLVL LAPSE RATES WILL SUPPORT AT LEAST AN ISOLATED TORNADO THREAT WITH THE INITIAL ACTIVITY. ALSO...WITH DCAPE VALUES APPROACHING 1500 J/KG...POTENTIAL FOR DAMAGING WINDS WITH BE FAIRLY HIGH. STORMS MAY TEND TO BECOME MORE OUTFLOW DOMINANT WITH TIME GIVEN MAGNITUDE OF LLVL WIND FIELDS ALONG WITH STORM SEEDING BECOMING MORE LIKELY AS STORMS INCREASE IN COVERAGE. THE DAMAGING WIND THREAT WILL BECOME INCREASINGLY LIKELY BY MID TO LATE AFTERNOON AS STORMS INCREASE IN COVERAGE WITHIN WEAKLY CAPPED AIR MASS AND COLD POOL GENERATION BECOMES ESTABLISHED. AN INTENSE FORWARD PROPAGATING MCS APPEARS LIKELY BY LATE THIS AFTERNOON AND EVENING...ESPECIALLY ACROSS EASTERN KANSAS AND WESTERN MISSOURI. MCS EXPECTED TO PROPAGATE SOUTH-SOUTHEASTWARD GIVEN MID LEVEL FLOW WHILE INTENSIFYING AND BEING AIDED BY STRENGTHENING LLJ. GIVEN MAGNITUDE OF INSTABILITY AND LARGE COLD POOL GENERATION EXPECTED...THE POTENTIAL FOR A WIDESPREAD DAMAGING WIND EVENT SEEMS POSSIBLE AS THE MCS RACES SOUTHWARD...WITH VERY STRONG WIND GUSTS POSSIBLE AT TIMES. NEXT CONCERN IS WITH POTENTIAL FOR HEAVY RAINFALL AS PRECIPITABLE WATER VALUES CLIMB ABOVE 1.5 IN BY THIS AFTERNOON. NAM BUFR SOUNDINGS SHOWING RAPID MOISTENING OF THE ATMOSPHERIC COLUMN BY MID AFTERNOON WHILE MAINTAINING STEEP LAPSE RATES THROUGHOUT THE EVENT. THIS SHOULD RESULT IN HEAVY RAINFALL RATES WITH ANY CONVECTION THAT DEVELOPS. HOWEVER...GIVEN THE SPEED OF SOUTHWARD PROPAGATION EXPECTED...DECIDED TO HOLD OFF ON ANY HEADLINES THINKING FLOODING SHOULD REMAIN LOCALIZED. MCS SHOULD BE SOUTH OF THE AREA BY 06-12Z TONIGHT AND HAVE TAPERED POPS ACCORDINGLY. OTHERWISE...NO SIGNIFICANT CHANGES MADE TO THE REMAINDER OF THE FORECAST. DEROCHE && .AVIATION... FOR THE EVENING HOURS...CLEAR SKIES WILL CONTINUE WITH WINDS DIMINISHING AND BACKING INTO THE SOUTH-SOUTHEAST. ATTENTION THEN TURNS TO SE NEBRASKA/SW IOWA LATE TONIGHT AS MODEST LOW LEVEL JET BEGINS TO DELIVER A WARM/MOIST AIRMASS NORTHWARD...INTERSECTING THE EDGE OF A STOUT CAPPING INVERSION. INITIAL MCS DEVELOPMENT APPEARS LIKELY IN THIS REGION BETWEEN 09 AND 12Z. WHILE CONDITIONS APPEAR FAVORABLE FOR SEVERE CONVECTION IMPACTING THE TERMINALS TOMORROW...THE QUESTION REMAINS TIMING. INITIAL MCS COULD TRANSLATE EAST/SOUTHEAST WITH A SECONDARY AREA DEVELOPING ALONG THE KS/MO BORDER BY EARLY AFTERNOON. CURRENT TAFS ARE LEANING TOWARD THIS EVOLUTION. VERY UNSTABLE AIRMASS...STRONG VERTICAL WIND SHEAR AND THE AMOUNT OF DRY/COOL MID LEVEL AIR UPSTREAM OVER THE CENTRAL PLAINS SUGGESTS THAT ONE OR MORE DAMAGING BOW ECHOES ARE LIKELY. PROB30 GROUP FOR NOW INDICATES THIS POTENTIAL WITH MOST LIKELY TIME PERIOD FOR STRONG/SEVERE CONVECTION. BOOKBINDER && .EAX WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE.

A VERY MOIST AIRMASS IS SPREADING BACK INTO THE REGION THIS MORNING AND WILL CONTINUE THROUGH THIS AFTERNOON. WITH ABUNDANT SUNSHINE FORECAST INTO THE EARLY AFTERNOON...AN EXTREMELY UNSTABLE AIRMASS IS EXPECTED TO BE IN PLACE AHEAD OF A STRONG COLD FRONT WHICH WILL PUSH INTO NORTHWEST MISSOURI AND NORTHEAST KANSAS DURING THE EARLY AFTERNOON HOURS. RAPID SEVERE THUNDERSTORM DEVELOPMENT IS EXPECTED ALONG THIS BOUNDARY...INITIALLY IN THE FORM OF SUPERCELLS CAPABLE OF PRODUCING LARGE HAIL...SOME POTENTIALLY VERY LARGE...AND POSSIBLY AN ISOLATED TORNADO. THESE STORMS ARE EXPECTED TO QUICKLY ORGANIZE INTO A LARGE SQUALL LINE AND ACCELERATE SOUTHWARD DURING THE AFTERNOON AND EARLY EVENING HOURS WITH THE POTENTIAL FOR A WIDESPREAD DAMAGING WIND EVENT WITH SOME VERY STRONG GUSTS POSSIBLE. IN ADDITION...THE COMBINATION OF INSTABILITY AND DEEP TROPICAL MOISTURE WILL RESULT IN TORRENTIAL RAINFALL WITH HOURLY RAINFALL AMOUNTS UPWARDS OF TWO INCHES POSSIBLE...WHICH COULD LEAD TO LOCALIZED FLOODING. PERSONS WITH OUTDOOR PLANS ON FATHERS DAY SHOULD REMAIN ALERT FOR RAPIDLY CHANGING WEATHER CONDITIONS AND BE PREPARED TO QUICKLY MOVE TO SAFE SHELTER IF THREATENING WEATHER APPROACHES. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME. .SPOTTER INFORMATION STATEMENT...
