NWS Kansas City, MO wrote its last area forecast discussion before the first event at Aug 13, 2:54 PM CST, 10 hours 46 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 354 PM CDT SUN AUG 13 2006 .DISCUSSION... SURFACES OBS SHOW A FRONT LOCATED IN EASTERN NEBRASKA THIS AFTERNOON. EARLY MORNING CONVECTION...ASSOCIATED WITH THE ISENTROPIC LIFT WITHIN THE PREFRONTAL TROUGH AHEAD OF THE FRONT...CONTINUED TO PERCOLATE ALONG FROM SOUTH CENTRAL KANSAS NORTHEAST THROUGH NEBRASKA AND IOWA...JUST BARLEY GRAZING THE EXTREME NORTHWEST CORNER OF MISSOURI AHEAD OF THE FRONT THROUGH THE EARLY AFTERNOON HOURS. IN THE BIGGER PICTURE THE FRONT TO OUR NORTH IS A SURFACE REFLECTION OF A TROUGH MOVING EAST THROUGH CENTRAL CANADA AND THE NORTHERN PLAINS. SUBTROPICAL MOISTURE WAS FEEDING INTO THE LEADING EDGE OF THE TROUGH WITH THE HELP OF A GULF COAST ANTICYCLONE. THE AFTERNOON HOURS WILL SAW LOW LEVEL LAPSE RATES CONTINUE TO STEEPEN ACROSS MISSOURI AND EASTERN KANSAS AS SURFACE TEMPERATURES CLIMB INTO THE 90S. EARLY AFTERNOON HOURS MLCAPE VALUES WERE RUNNING AS HIGH AS 3500 J/KG IN FAR NORTHWEST MISSOURI...WITH VALUES TRENDING DOWN AS YOU MOVE TOWARDS CENTRAL MISSOURI. UPPER AIR SOUNDING FROM 12Z...AND RUC ANALYSIS...STILL SHOWED A NICE MIDLEVEL CAP IN PLACE FROM EAST CENTRAL KANSAS INTO CENTRAL MISSOURI DUE TO WARM 600 MB TEMPERATURES. A FEW ISOLATED STORMS POPPED UP TO OUR SOUTH OVER THE OZARKS...BUT WERE NOT MOVING MUCH AND WERE VISIBLY STRUGGLING UNDER THE CAP. HAVE LEFT SOME CHANCE POPS IN ACROSS EAST CENTRAL KANSAS AND CENTRAL MISSOURI FOR THE LATER AFTERNOON HOURS IN CASE ANYTHING DRIFTS NORTH. THE STORIES A LITTLE DIFFERENT IN THE NORTHEAST CORNER OF KANSAS AND NORTHWEST CORNER OF MISSOURI EAST ALONG THE IOWA BORDER. NO CAP WAS EVIDENT ACROSS THESE BORDER AREAS AS OF 2 PM WITH SURFACE BASED CAPE VALUES OF 4000+ J/KG. WITH 0-3 KM SHEAR RANGING ABOVE 20 KTS THERE IS ENOUGH SHEAR TO ORGANIZE STORM ACTIVITY. MODIFIED SOUNDINGS FROM KOAX AND KTOP BOTH INDICATE THAT THE THERMODYNAMIC PROFILE WOULD LEND ITSELF TOWARDS STRONG DOWNBURST WINDS WITH AN INVERTED V SOUNDING. THE HAIL THREAT WILL BE MITIGATED BY FREEZING LEVELS NEAR 16 KFT...BUT ANY LONG LIVED ORGANIZED STORMS MIGHT BE ABLE TO PRODUCE IT. IN ADDITION TO HAIL AND WINDS HEAVY RAIN WILL BE A CONCERN AS PRECIPITABLE WATER VALUES SPIKE TO NEAR 2 INCH IN THE PREFRONTAL TROUGH AHEAD OF THE FRONT. STORMS ARE EXPECTED TO SPREAD SOUTHEAST ACROSS EASTERN KANSAS AND THE NORTHERN HALF OF MISSOURI AS THE FRONT SLOWLY PUSHES SOUTH. THE THREAT FOR WIDESPREAD SEVERE IS EXPECTED TO REMAIN CONFINED ALONG THE NORTHERN EDGE OF THE CWA INTO THE EVENING HOURS. SHEAR INCREASES AS THE FRONT PUSHES INTO NORTHERN MISSOURI...BUT THE INSTABILITY FALLS OFF RAPIDLY AS SUNSET TAKING THE FUEL FOR THE SEVERE STORMS WITH IT. THIS IS WHY THE CURRENT SEVERE THUNDERSTORM WATCH...718 UNTIL 10 PM...IS CONFINED TO AREAS ALONG AND NORTH OF A LINE FROM ATCHISON KANSAS THROUGH GALLATIN MISSOURI AND UNIONVILLE. MONDAY AND TUESDAY WILL SEE TEMPERATURES PREVAIL AROUND AND JUST BELOW NORMAL AS A COOL CANADIAN SURFACE HIGH SETTLES SOUTHEAST BEHIND THE FRONT MOVING THROUGH TONIGHT. FOR THE LATER HALF OF THE WEEK A RIDGE WILL TRAVERSE THE CENTRAL PLAINS. THIS WILL CONTINUE THE UPWARD TREND IN OUR TEMPERATURES ACROSS THE FORECAST AREA...WITH ABOVE NORMAL TEMPERATURES REAPPEARING MOST EVERYWHERE BY THURSDAY. GFS AND ECMWF BOTH INDICATE THAT ANY NUMBER OF SHORTWAVES WILL ALSO BE SWEEPING THROUGH THE NORTHERN PLAINS AS THE RIDGE MOVES THROUGH THE CENTRAL AND SOUTHERN SECTIONS. THIS PATTERN PAINTS ANOTHER PICTURE FULL OF CONVECTION ACROSS THE NORTHERN PLAINS STARTING LATE IN THE WORK WEEK AND THROUGH NEXT WEEKEND. HAVE CONTINUED TO HANDLE THIS WITH SLIGHT CHANCE POPS ACROSS THE NORTHERN REACHES OF THE FORECAST AREA DUE TO THE HIGH DEGREE OF UNCERTAINTY IN THE TIMING AND PLACEMENT OF THESE SMALL WAVES AND ASSOCIATED CONVECTION. CUTTER && .PREV DISCUSSION... 1137 AM... MADE SOME REVISIONS TO AFTERNOON FORECASTS. CONCERNED WITH SOME AIRMASS TYPE STORMS DEVELOPING OVER WESTERN AND CENTRAL MISSOURI IF TEMPERATURES CAN REACH CONVECTION TEMPERATURES IN THE MIDDLE 90S. ONE INHIBITOR MAY BE THE MID LEVEL LAPSE RATES..WITH A WARM NOSE SHOWING UP IN THE 500 TO 600 MB LEVELS. ANOTHER PROBLEM MAY BE THE CURRENT CLOUDINESS THAT REMAINS FROM EARLIER ISENTROPIC LIFT...HOLDING DOWN TEMPERATURES JUST A BIT. MAIN CONCERN FROM THESE TYPES OF STORMS WILL BE DAMAGING WINDS...AS LOWER LEVELS...BELOW 800 MB...IS STILL PRETTY DRY. REGARDING NORTHWEST MISSOURI...STILL LOOKING LIKE THE FRONT AND ASSOCIATED CONVECTION WILL NOT BE MUCH OF A FACTOR UNTIL AFTER 5 PM. CURRENT ACTIVITY IS ON THE DECREASE IN THAT AREA WITH DECREASING 850 WINDS. STILL SOME CONCERN FOR SEVERE WEATHER INITIALLY...BUT AS EVENING PROGRESSES...AND FRONT MOVES FURTHER SOUTH...SHEAR NOT AS IMPRESSIVE AND LOSS OF SURFACE HEATING WILL MEAN LESS INSTABILITY FOR THE STORMS TO WORK WITH. STILL THINK THE POTENTIAL WILL BE THERE FOR HEAVIER RAIN AS PWATS WILL BE GREATER THAN 2 INCHES. PC 839 AM CDT SUN... THIS MORNINGS LOW LEVEL JET HAS INDUCED ISENTROPIC LIFT ON THE 310K SURFACE ACROSS EASTERN NEBRASKA. WITH THE JET LEVEL WINDS ORIENTED FROM SOUTHWEST TO NORTHEAST THE STORMS THIS MORNING HAVE BEEN SLOW TO PUSH EAST. HOWEVER...LATEST RADAR TRENDS INDICATE THAT THE STORMS MIGHT GRAZE THE FAR NORTHWEST CORNER OF MISSOURI...SO I HAVE ADDED SOME SCATTERED THUNDERSTORM POPS TO THE MORNING HOURS. FARTHER SOUTH...THE SCATTERED SHOWERS AND STORMS IN EXTREME EAST CENTRAL KANSAS HAVE DISSIPATED...SO MORNING THUNDERSTORM CHANCES ALONG THE STATE LINE WERE REMOVED. CUTTER 345 AM... WV IMAGERY DEPICTS SEVERAL POTENT SHORTWAVE FEATURES WHICH WILL HELP DETERMINE SENSIBLE WEATHER ACROSS THE CENTRAL PLAINS FOR THE NEXT 48 HOURS. INITIAL LEAD WAVE...CURRENTLY OVER NRN MANITOBA...HAS HELPED DAMPEN AND DISPLACE THE HIGH AMPLITUDE RIDGE WHICH HAS RESIDED OVER THE CENTRAL CONUS FOR THE PAST SEVERAL DAYS. SECONDARY TRAILING WAVE IS CURRENTLY SEEN OVER CNTRL MONTANA...AND THIS FEATURE WILL TRAVERSE EWD INTO THE WRN GREAT LAKES BY MONDAY MORNING. AHEAD OF THIS SIGNIFICANT WAVE...SEVERAL MORE SUBTLE WAVE FEATURES HAVE EJECTED INTO THE HIGH PLAINS ON THE WRN PERIPHERY OF THE RIDGE AXIS...AND HAVE HELPED INITIATE A CONVECTIVE SYSTEM ALONG A PREFRONTAL SURFACE TROF OVER WRN NEBRASKA AND SOUTH DAKOTA. THIS COMPLEX...CURRENTLY OVER CNTRL NEBRASKA...IS FORECAST TO CONTINUE TO PROPAGATE NORTHEAST INTO NORTHWESTERN IOWA THROUGH THE MORNING HOURS. FORECAST FOR THE IMMEDIATE SHORT TERM IS BECOMING COMPLICATED BY ELEVATED CONVECTION DEVELOPING OVER CENTRAL AND EASTERN KANSAS THIS MORNING. THIS ACTIVITY APPEARS TO BE ASSOCIATED WITH ISENTROPIC LIFT ALONG THE 305K LAYER...AND APPEARS TO BE BEST HANDLED BY THE RUC...AND TO SOME DEGREE THE NAM/WRF. COVERAGE APPEARS TO BE ISOLATED AT BEST...AND IS FORECAST TO DISSIPATE SHORTLY AFTER SUNRISE...SO FOR THE TIME BEING...WILL NOT INTRODUCE ANY MENTION IN THE FORECAST. FOCUS THIS AFTERNOON AND EVENING WILL BE CONVECTIVE INITIATION ALONG AND AHEAD OF A SEASONABLY STRONG FRONTAL BOUNDARY FORECAST TO DIVE SOUTHEAST FROM THE DAKOTAS. A DEEP WELL MIXED BOUNDARY LAYER WILL DEVELOP THIS AFTERNOON IN THE WARM SECTOR OVER THE LOWER MISSOURI RIVER VALLEY. 8H TEMPERATURES BETWEEN +20C AND +24C WILL ALLOW TEMPERATURES TO RISE QUICKLY INTO THE 90S...BARRING SIGNIFICANT INFLUENCE FROM ELEVATED CONVECTIVE DEBRIS ORIGINATING THIS MORNING IN KANSAS. THIS WILL CREATE A MODERATELY UNSTABLE AND WEAKLY CAPPED ENVIRONMENT WITH MLCAPES 2000-3000 J/KG. FORECAST SOUNDINGS INDICATE A MODIFIED INVERTED-V TYPE PROFILE WITH T/TD SPREADS ON THE ORDER OF 25F TO 30F DURING PEAK HEATING. LIMITING FACTORS FOR WIDESPREAD AFTERNOON WARM SECTOR CONVECTION APPEAR TO BE LACK OF A DISCERNIBLE TRIGGER TO SUPPORT DEVELOPMENT AND WEAK LOW LEVEL CONVERGENCE REMOVED FROM THE APPROACHING FRONTAL BOUNDARY. HOWEVER...ISOLATED LATE AFTERNOON THUNDERSTORMS STILL APPEAR POSSIBLE AREA WIDE...WITH SOME CHANCE FOR LOCALLY DAMAGING WINDS BEFORE THE FOCUS SHIFTS TO MORE ROBUST THUNDERSTORMS ALONG THE FRONTAL BOUNDARY IN NORTHWEST MISSOURI. MODELS HAVE BEEN VERY CONSISTENT SHOWING A POTENT COLD FRONT IMPINGING ON THE NORTHWEST CORNER OF MISSOURI BY THE LATE AFTERNOON/EARLY EVENING HOURS. LOW LEVEL INSTABILITY...UPPER LEVEL SUPPORT IN THE FORM OF JET STREAK ENERGY IN EXCESS OF 70 KT NORTH OF THE BOUNDARY...AND INCREASING LOW LEVEL FRONTAL CONVERGENCE WILL ACT TO INITIATE WIDESPREAD THUNDERSTORM DEVELOPMENT. OVERALL SHEAR PROFILES ACROSS THE LOWER MISSOURI RIVER VALLEY WILL BE RATHER WEAK...AND THE CONVECTION WILL LIKELY TAKE THE FORM OF LINE SEGMENTS...WITH THE POSSIBILITY OF DAMAGING WINDS IN THE INITIAL FORMATION STAGES...BEFORE TRANSITIONING TO A MORE BROAD CONVECTIVE COMPLEX WITH THE LOSS OF INSTABILITY DURING THE EVENING HOURS. DESPITE PW VALUES EXCEEDING 2 INCHES IN THE WARM SECTOR...EXCESSIVE RAINFALL APPEARS LIMITED GIVEN THE PROGRESSIVE NATURE OF THE FRONTAL BOUNDARY AND LIKELY EFFECTIVE COLD POOL GENERATION. FRONTAL BOUNDARY LOOKS AS IF IT WILL MAKE QUICK PROGRESS THROUGH THE AREA BY EARLY MONDAY AFTERNOON WITH NICE POST FRONTAL PRESSURE RISES. TRIMMED BACK POPS FOR MONDAY AS COOLER AIR IN LARGE SCALE SUBSIDENCE ADVECTS TOWARDS THE AREA. TUESDAY MORNING LOOKS TO BE THE COOLEST FOR THE REGION IN OVER A MONTH WITH PLUMMETING DEWPOINTS AND SURFACE HIGH PRESSURE CENTERED OVER WESTERN MISSOURI. GENERALLY FOLLOWED THE SLIGHTLY WARMER MET GUIDANCE IN THIS TIME PERIOD...ALTHOUGH THE CHILLY MAV NUMBERS WOULD BE POSSIBLE IF DEWPOINTS CRASH AS MUCH AS THAT GUIDANCE PACKAGE INDICATES. FORECAST WAS UNCHANGED AFTER TUESDAY AS THERE REMAINS SOME UNCERTAINTY TO THE PATTERN EVOLUTION INTO NEXT WEEKEND. 21 && .EAX WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. WFO EAX
