NWS Kansas City, MO wrote its last area forecast discussion before the first event at Apr 3, 2:46 PM CST, 11 hours 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 246 PM CST THU APR 3 2003 EARLY AFTERNOON SURFACE ANALYSIS DEPICTS LOW CENTERED OVER WEST CENTRAL IOWA...WITH ASSOCIATED COLD FRONT EXTENDING SOUTHWEST ACROSS THE TIP OF SOUTHEAST NEBRASKA/NORTHWEST MISSOURI INTO CENTRAL KANSAS. WHILE ADEQUATE INSTABILITY IS PRESENT JUST AHEAD OF THE BOUNDARY...AS IS EVIDENT IN SURFACE DEWPOINTS IN THE MID TO UPPER 50S...LIS AROUND -4 TO -5...AND LAPSE RATES AROUND 7.5 J/KG...LACK OF DIURNAL DESTABILIZATION DUE TO MID TO UPPER LEVEL CLOUD COVER SHOULD INHIBIT THE BULK OF THUNDERSTORM DEVELOPMENT UNTIL LATER THIS EVENING/TONIGHT. BETTER ISENTROPIC LIFT...FORCING...AND SUPPORT FROM A 40-50 KNOT (ETA-PROGGED) LOW LEVEL JET SHOULD YIELD MORE FOCUSED THUNDERSTORM DEVELOPMENT (ELEVATED IN NATURE) BETWEEN 06Z AND 12Z FRIDAY ACROSS THE ENTIRE AREA. EXPECT THE SEVERE THREAT FROM THIS ACTIVITY TO BE THE POTENTIAL FOR LARGE HAIL...MAINLY ALONG AND NORTH OF THE SURFACE BOUNDARY PROGGED TO LIE ALONG A KANSAS CITY TO MACON LINE DURING THE 06Z-12Z FRIDAY TIME FRAME. IN ADDITION...THE 18Z META IS INDICATING THAT THUNDERSTORMS MAY CONGEAL INTO AN MCS OVERNIGHT...AND LINGER ACROSS THE AREA UNTIL MID TO LATE FRIDAY MORNING...SO MAY HAVE TO SLOW DOWN THE PRECIP-ENDING TIMING. SCHMIT HIGH PRESSURE MOVES ACROSS THE REGION FRIDAY NIGHT INTO SATURDAY. STRONG COLD ADVECTION WILL BE OFFSET BY MOSTLY SUNNY/PARTLY CLOUDY SKIES. HAVE THEREFORE GONE CLOSER TO ETA GUIDANCE. ISENTROPIC LIFT OVER THE SURFACE FRONT DEVELOPS ACROSS THE REGION OVERNIGHT SATURDAY...AHEAD OF THE NEXT SHORTWAVE TO MOVE OUT OF THE CENTRAL ROCKIES. PRECIP MAY HAVE A DIFFICULT TIME REACHING THE GROUND INITIALLY. HOWEVER DO EXPECT SHOWERS/THUNDERSTORMS TO MOVE ACROSS MUCH OF THE FORECAST AREA BY SUNDAY MORNING. AVN CONTINUES TO BE FARTHER NORTH WITH THE POSITION OF THE SURFACE FRONT BY MIDDAY SUNDAY. HAVE LEANED MORE TOWARD THE ETA POSITIONING OF THE FRONT AT THAT TIME AND PLACED THE FRONT ACROSS CENTRAL MISSOURI. ISENTROPIC LIFT OVER THE FRONT CONTINUES INTO SUNDAY AFTERNOON ACROSS MOST OF THE AREA. BY SUNDAY EVENING...EXPECT THE PRECIP TO MAINLY BE NORTH OF THE COLD FRONT...ACROSS NORTHERN MISSOURI. HAVE BUMPED POPS UP TO LIKELY ON SUNDAY FOR MOST OF THE FORECAST AREA. PRECIP SHOULD BE MAINLY RAIN...ALTHOUGH THE NORTHWEST CORNER OF MISSOURI MAY HAVE A CHANGE OVER TO SNOW SUNDAY/SUNDAY NIGHT. BEST MOISTURE SHOULD BE MOVING OUT OF THAT AREA...SO EXPECT SNOW AMOUNTS TO BE LIGHT. PRECIP MOVES OUT ON MONDAY LEAVING REMAINDER OF THE WEEK DRY. STORM SYSTEM OVER THE WEEKEND WILL USHER IN COOLER TEMPERATURES FOR THE START OF THE WORK WEEK. HOWEVER READINGS WELL INTO THE 60S WILL BE BACK WEDNESDAY AND THURSDAY. NRR 1015 AM... UPDATES WILL BE OUT SHORTLY TO MODIFY TEMPERATURE TRENDS AND ADD SCATTERED SPRINKLES. TEMPERATURES HAVE BEEN SLOW TO RISE THIS MORNING DUE TO THE EXTENSIVE CLOUD COVER. WILL GENERALLY LOWER HIGHS ABOUT A CATEGORY. LS 630 AM THU... SHOWERS AND THUNDERSTORMS HAVE MOVED OUT OF NORTHEAST MISSOURI AS THE THETA-E ADVECTION HAS SHIFTED INTO NORTHERN ILLINOIS. AN UPDATE TO THE FORECAST HAS BEEN ISSUED TO REMOVE PRECIPITATION FROM THE NORTHEAST MISSOURI COUNTIES. KOCH 415 AM THU... STEEP LAPSE RATES AND SUFFICIENT MID LEVEL MOISTURE ARE PRESENT THIS MORNING AND HAVE SPAWNED SOME WARM ADVECTION SHOWERS AND THUNDERSTORMS OVER NORTHERN MISSOURI AND SOUTHERN IOWA. THETA-E ADVECTION AT 750MB SEEMS TO BE THE TRIGGER FOR THESE SHOWERS AND CLOUD BASES ARE VERY HIGH WITH THESE CELLS. AS THE AXIS OF THETA-E ADVECTION MOVES EAST THIS MORNING, SHOWERS SHOULD COME TO AN END OVER NORTHERN MISSOURI RIGHT AROUND SUNRISE. SURFACE DEWPOINTS HAVE CLIMBED INTO THE MID 50S OVER EASTERN KANSAS AND NORTHERN MISSOURI OVERNIGHT SETTING THE STAGE FOR THE POSSIBILITY OF SURFACE BASED CONVECTION ALONG A COLD FRONT EXPECTED TO ARRIVE IN NORTHWEST MISSOURI LATE THIS AFTERNOON. IT IS TOUGH TO DETERMINE HOW DEEP THE MOISTURE WILL BE. THE ETA 850MB DEWPOINT FIELD INITIALIZED POORLY AT 00Z. THE AVN WAS BETTER AND I FAVOR IT OVER THE ETA WHICH POOLS MORE MOISTURE AHEAD OF THE FRONT THIS AFTERNOON AND EVENING. WITH WIND TRAJECTORIES IN THE 925 TO 850MB LAYER PROJECTED TO HAVE A SOUTHWESTERLY COMPONENT BY LATE IN THE DAY, I EXPECT THE BEST DEEP LAYER MOISTURE TO BE OVER CENTRAL AND EASTERN MISSOURI. THEREFORE I HAVE THE BEST CHANCES FOR THUNDER (40%) THIS EVENING FROM CHILLICOTHE TO KIRKSVILLE. DRY MID LEVELS WILL CONTRIBUTE TO THE DAMAGING WIND THREAT ESPECIALLY EARLY IN THE EVENING WITH SURFACE BASED STORMS. HAIL IS ALSO A CONCERN. PRECIPITATION CHANCES DWINDLE SOUTH OF HIGHWAY 36 AS LOW LEVEL WESTERLIES SWEEP THE MOISTURE TO THE EAST AS THE FRONT DROPS SOUTH TONIGHT. THE NEXT CHANCE FOR PRECIPITATION WILL ARRIVE LATE SATURDAY NIGHT INTO SUNDAY AS THE MAIN UPPER TROUGH EJECTS INTO THE PLAINS. I FAVOR THE SURFACE LOW POSITION OF THE ETA BY 12Z SUNDAY. I THINK THAT THE GFS IS TOO FAR NORTH CONSIDERING THE STRENGTH OF THE SURFACE HIGH OVER THE GREAT LAKES. WITH THIS SAID, MOST OF KANSAS AND MISSOURI WILL BE IN THE COLD SECTOR ON SUNDAY SO THE SEVERE WEATHER POTENTIAL WILL BE LOW WITH THIS SYSTEM. THE DAY SHIFT WILL NEED TO CONSIDER LOWERING HIGH TEMPERATURES ON SUNDAY IF THE ETA SOLUTION HOLDS TRUE. KOCH .EAX... KS...NONE. MO...NONE.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL AND WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS. .DAY ONE...THIS AFTERNOON AND TONIGHT SCATTERED SEVERE THUNDERSTORMS CAPABLE OF PRODUCING DAMAGING WIND GUSTS AND LARGE HAIL ARE POSSIBLE IN EXTREME NORTHEAST KANSAS AND IN NORTHERN MISSOURI. THE MAJORITY OF THE SEVERE THUNDERSTORM ACTIVITY IS EXPECTED TO REMAIN ALONG AND NORTH OF AN ATCHISON KANSAS TO CHILLICOTHE TO MACON LINE. THESE THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG A COLD FRONT AS IT ENTERS NORTHWEST MISSOURI LATE THIS AFTERNOON. LIMITED ATMOSPHERIC MOISTURE SHOULD KEEP SEVERE THUNDERSTORMS FROM BECOMING WIDESPREAD...HOWEVER ANY STORMS THAT FORM WILL BE CAPABLE OF PRODUCING DAMAGING WIND GUSTS AND HAIL LARGER THAN PENNIES. IN ADDITION TO THE THUNDERSTORM POTENTIAL...FIRE DANGER REMAINS HIGH OVER NORTHERN MISSOURI AND NORTHEAST KANSAS TODAY UNDER THE INFLUENCE OF STRONG SOUTH TO SOUTHWEST WINDS AT 20 TO 30 MPH. ALSO...LIGHTNING ASSOCIATED WITH ANY THUNDERSTORM ACTIVITY WILL POSE AN ADDITIONAL FIRE HAZARD. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY THUNDERSTORMS ARE FORECAST FOR SATURDAY NIGHT INTO MONDAY ACROSS THE ENTIRE REGION.
