What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Kansas City, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at May 11, 2:51 PM CDT, 2 hours 48 minutes earlier.
Area forecast discussion, May 11, 2:51 PM CDT, 2 hours 48 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 251 PM CDT WED MAY 11 2011 .DISCUSSION... WEAK SHORTWAVE WHICH INITIATED THE CONVECTION THIS MORNING HAS DEPARTED THE FORECAST AREA. A WEAK SUBSIDENCE INVERSION WAS NOTED IN THE WAKE OF THE WAVE ON THE TOPEKA 18Z SOUNDING. REGARDLESS...THE CAP IS RATHER WEAK WITH INSTABILITY AROUND 2500 J/KG-3500 J/KG. DUE TO THE HIGH INSTABILITY...WIDELY SCATTERED SHOWERS AND THUNDERSTORMS WERE DEVELOPING THIS AFTERNOON. GIVEN THE WEAK SHEAR ENVIRONMENT...THE PRIMARY THREATS ARE LARGE HAIL AND DAMAGING WINDS. NEXT CONCERN IS THE CONVECTION UPSTREAM IN OKLAHOMA AND SOUTH CENTRAL KANSAS...AHEAD OF A NEARLY STATIONARY UPPER LEVEL LOW IN SOUTHERN COLORADO. CONVECTION WAS GENERALLY MOVING NORTH NORTHEAST AS MID LEVEL WINDS BACK AHEAD OF THE LOW. DUE TO THE SLOW MOVEMENT AND BACKING WINDS...THE CONVECTION TO THE SOUTHWEST IN KANSAS AND OKLAHOMA WILL BE SLOW TO MOVE SUFFIFICIENTLY EAST...NOT LIKELY ARRIVING INTO EXTREME WESTERN MISSOURI UNTIL AT LEAST 7 OR 8 PM. THE ONLY EXCEPTION MAY IN EXTREME NORTHWEST MISSOURI...JUST TO THE SOUTH OF THE STATIONARY FRONT IN SOUTHEASTERN NEBRASKA. SBCAPES WILL BE AROUND 2500-3000 J/KG THIS EVENING...BUT LOW AND DEEP LAYER SHEAR WILL BE WEAK. DESPITE THE WEAK SHEAR...LARGE HAIL AND DAMAGING WINDS ARE POSSIBLE DUE TO THE HIGH INSTABILITY. MODELS CONTINUE TO SUGGEST THAT THE UPPER LEVEL LOW WILL BE VERY SLOW TO MOVE EAST. THIS APPEARS REASONABLE GIVEN THE BLOCK OFF THE EAST COAST. THE INSTABILITY WILL SIGNIFICANTLY DIMINISH AFTER SUNSET WITH THE INTENSITY OF THE CONVECTION DECREASING AS IT MOVES EAST. ON THURSDAY...THE UPPER LEVEL LOW DRIFTS INTO CENTRAL AND WESTERN KANSAS WITH THE ATTENDANT SURFACE LOW SHIFTING EAST INTO EASTERN KANSAS WITH THE FRONT SAGGING INTO NORTHWEST MISSOURI. THESE FEATURES ALONG WITH ANY WEAK SHORTWAVES WILL TRIGGER SCATTERED THUNDERSTORMS ONCE AGAIN IN A HIGH INSTABILITY AND LOW SHEAR ENVIRONMENT. LARGE HAIL...DAMAGING WINDS AND LOCALLY HEAVY RAINFALL ARE POSSIBLE. ON THURSDAY NIGHT AND FRIDAY...THE NAM AND GFS ARE CONSISTENT IN SHIFTING THE UPPER LEVEL LOW EAST SOUTHEAST INTO SOUTHERN MISSOURI. THE PRECIPITATION WILL GRADUALLY END FROM THE NORTHWEST DURING THIS PERIOD. DB MEDIUM RANGE (SATURDAY THROUGH WEDNESDAY)... MODELS HAVE COME INTO BETTER AGREEMENT WITH HANDLING OF UPPER DOUBLE LOW EVOLUTION AS THEY PRETTY MUCH AGREE WITH SWINGING THE NORTHERN ONE THROUGH THE UPPER MIDWEST AS THE FIRST ONE SLOWLY SWINGS THROUGH TO THE EAST. THIS FIRST WAVE SHOULD HAVE MOVED ON BY THE EXTENDED AND THE SECOND WAVE WILL PROVIDE SOME INSTABILITY SHOWERS POTENTIALLLY ON SATURDAY AND MORE LIKELY ON SUNDAY. AFTER THAT SURFACE RIDGING WILL BRING QUIET AND CONTINUED SLIGHTLY COOL THROUGH WEDNESDAY. BAILEY && .AVIATION... FOR THE 18Z TAFS...TOUGH FORECAST THROUGH THURSDAY MORNING WITH THE FORECAST REVOLVING AROUND THE TIMING OF CONVECTION. AN UPPER LOW WAS NEARLY STATIONARY IN SOUTHERN COLORADO WITH THE CONVECTION AHEAD OF THE LOW IN NORTH CENTRAL KANSAS SOUTH INTO OKLAHOMA. THE LOW WILL BE VERY SLOW TO MOVE EAST TODAY THROUGH THURSDAY. BEST ESTIMATE IS THAT CONVECTION IN KANSAS WILL MOVE INTO THE TERMINALS AFTER 00Z AND SLOWLY DIMINISH DURING THE EVENING AS INSTABILITY DECREASES. NUMERICAL GUIDANCE SUGGEST THAT AN MVFR DECK MAY FORM LATE TONIGHT DUE TO SATURATION OF THE LOWER LEVELS AND NOCTURNAL COOLING. CANNOT ARGUE WITH THE GUIDANCE AT THIS TIME...BUT CONFIDENCE IS NOT HIGH. DB && .EAX WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. &&
