NWS Kansas City, MO wrote its last area forecast discussion before the first event at May 19, 2:35 AM CST, 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 335 AM CDT WED MAY 19 2004 .DISCUSSION... WILL CONTINUE HIGH CHANCE TO LIKELY POPS FOR THIS MORNING FOR ONGOING PRECIP. PRECIP IS EXPECTED TO DIMINISH AS LOW LEVEL JET WEAKENS THIS MORNING. HEAVY RAIN PRODUCING THUNDERSTORMS CONTINUE TO TRAIN ACROSS THE KANSAS CITY METRO AREA TO CENTRAL MISSOURI. WILL CONTINUE FLASH FLOOD WATCH AT LEAST UNTIL 6AM. MAIN CONCERN WITH THIS PACKAGE CONTINUES TO BE PRECIP CHANCES THROUGH THE NEXT SEVERAL DAYS. RIDGE IS PROGGED TO BUILD IN TODAY...PUSHING THE FRONT BACK NORTH. CLOUDS MAY BE A LITTLE STUBBORN THIS MORNING...SO HAVE LOWERED EXPECTED HIGHS A DEGREE OR TWO. THE FRONT MAY ONLY MAKE IT TO NORTHEAST MISSOURI BY THIS AFTERNOON. HAVE MAINTAINED A CHANCE FOR THUNDERSTORMS FOR MAINLY NORTHEAST MISSOURI TO ACCOUNT FOR THAT. CONTINUED THUNDERSTORM CHANCES ACROSS NORTHERN MISSOURI OVERNIGHT. THAT REGION WILL BE CAUGHT IN THE MIDDLE OF A NORTHWARD MOVING FRONT AND ANOTHER COLD FRONT DROPPING SOUTH ACROSS THE DAKOTAS AND NEBRASKA. MODELS DIFFER ON POSITION OF SURFACE BOUNDARY BY THURSDAY. ETA KEEPS THE FRONT FARTHER SOUTH OVER NORTHERN MISSOURI...WHILE THE GFS PUSHES IT FARTHER NORTH ACROSS CENTRAL IOWA AND NORTHERN ILLINOIS. AM INCLINED TO LEAN TOWARD THE GFS WHICH IS HANDLING THE CURRENT SITUATION BETTER...AND BOTH MODELS PROG UPPER LEVEL RIDGE TO BUILD IN ACROSS THE SOUTH. FOR NOW HAVE SPLIT THE DIFFERENCE WITH FRONTAL POSITION (ACROSS SOUTHERN IOWA INTO CENTRAL ILLINOIS) WHICH MATCHES WELL WITH SURROUNDING OFFICES. GOING TEMP FORECAST LOOKS PRETTY GOOD SO MADE ONLY VERY MINOR ADJUSTMENTS HERE AND THERE. NRR && .PREV DISCUSSION... 1019 PM TUE... THE SYNOPTIC FRONT DRAPED ACROSS MISSOURI HAS PROVIDED THE FOCUS FOR ELEVATED THUNDERSTORMS ACTIVITY THIS EVENING. WITH THE WEAK LOW LEVEL JET POINTING TOWARDS KANSAS CITY...STORMS WITHIN THAT VICINITY HAVE BEEN ABLE TO MAKE FULL USE OF THE ABUNDANT INSTABILITY (CAPES IN THE 1000-1500 J/KG RANGE). HOWEVER...WITH NOTHING OTHER THAN THE WEAK JET TO FOCUS THIS ACTIVITY...WIDE SPREAD SEVERE ACTIVITY IS NOT EXPECTED. HENCE...NO SEVERE THUNDERSTORM WATCH IS ANTICIPATED. HOWEVER...WITH AND PRECIPITABLE WATER VALUES IN THE ONE PLUS INCH RANGE HEAVY RAIN IS OF PRIMARY CONCERN. THIS ACTIVITY IS EXPECTED TO CONTINUE TO TRACK ACROSS EAST CENTRAL KANSAS INTO CENTRAL MISSOURI OVERNIGHT. WITH THE RAINFALL FROM THE MCS ACTIVITY THIS MORNING...FLASH FLOOD GUIDANCE VALUES HAVE DROPPED OFF NOTICEABLE FOR THESE AREAS. THEREFORE A FLASH FLOOD WATCH HAS BEEN ISSUED FOR AREAS ALONG AND SOUTH OF A LINE FROM ST JOSEPH THROUGH CHILLICOTHE AND MOBERLY...AND NORTH OF A LINE FROM DREXEL THROUGH WARRENSBURG TO SEDALIA AND BOONVILLE...TILL 6AM. CUTTER 335 PM... MAIN FORECAST CONCERN IN THE SHORTER TERM IS WITH CHANCES OF PRECIPITATION AS PATTERN REMAINS QUITE UNSETTLED. WEAK WAVES IN FLOW ARE DIFFICULT AT BEST TO TIME. IN THE VERY NEAR TERM...WATCHING BOUNDARY THAT APPEARS TO BE SET UP FROM NEAR WICHITA...TO JUST SOUTH OF KANSAS CITY THEN INTO CENTRAL MISSOURI. WIND FIELDS IN MISSOURI STILL QUITE CHAOTIC DUE TO EARLIER CONVECTION SO CONVERGENCE ALONG THIS BOUNDARY IN THAT AREA IS MINIMAL. HOWEVER...WINDS ARE PICKING UP IN SOUTHEAST KANSAS AND COULD SEE ENOUGH LIFT TO GET SOMETHING BREAKING THROUGH THE CAP AND GOING ALONG THE FRONT JUST TO THE SOUTHWEST OF FORECAST AREA TOWARD 00Z. RUC MODEL HAS BEEN DEPICTING THIS SCENARIO FAIRLY WELL. SHOULD SEE CONVECTION BUILD EASTWARD INTO WEST CENTRAL MISSOURI ALONG THIS BOUNDARY WHERE ENOUGH SUNSHINE HAS CREATED SOME INSTABILITY THIS AFTERNOON. BUT CORFIDI VECTORS WOULD INDICATE IF THESE STORMS CAN BUILD INTO A COMPLEX...THEY WOULD WANT TO TREND SOUTHWARD WHICH MAKES SENSE GIVEN WHERE BETTER MOISTURE AND INSTABILITY RESIDE INTO NORTHEAST OKLAHOMA. IF A COMPLEX DOES DEVELOP...SHOULD HOLD BACK NORTHWARD MOVEMENT OF FRONT LATER TONIGHT AND ON WEDNESDAY MORNING. HAVE PULLED THUNDERSTORM CHANCES BACK FURTHER SOUTH ON WEDNESDAY MORNING TO ACCOUNT FOR THIS SLOWER RETURN. BY AFTERNOON...WITH BUILDING UPPER RIDGE...SHOULD SEE FRONT TAKE A JUMP UP TO THE NORTH AS WINDS PICK UP FROM THE SOUTH IN RESPONSE TO A DEVELOPING SURFACE WAVE IN WEST CENTRAL KANSAS. WILL LEAVE A CHANCE OF STORMS IN THE AFTERNOON NEAR IOWA BORDER...BUT EXPECTED TO BE PRETTY CAPPED ACROSS REST OF FORECAST AREA IN THE AFTERNOON. ON THURSDAY...SOME QUESTION ON WHERE FRONT WILL BE SETTING UP. ETA A LITTLE FURTHER SOUTH WITH IT SLICING INTO NORTHERN MISSOURI BY MIDDAY WHEREAS GFS KEEPS IT IN SOUTHERN IOWA. WITH WARM AIR MASS IN PLACE...WILL LEAN TOWARD GFS SOLUTION...WITH ONLY LOW POPS REMAINING IN THE EXTREME NORTHERN AREAS OF FORECAST REGION. PC IN THE LAST HALF OF THE FORECAST AN AMPLIFIED WEST COAST TROUGH AND EAST COAST RIDGE WILL DOMINATE THE NATION. THIS AMPLIFIED PATTERN WILL BE THE RESULT OF A STRONG EAST PACIFIC BLOCKING RIDGE THAT IS FORECAST TO HOLD STRONG THROUGH NEXT WEEK. THE LATEST RUNS OF THE MID RANGE MODELS ARE...IN GENERAL...ALL TRENDING TOWARDS THE SOLUTION OFFERED BY THE ECMWF. THE ONE NOTABLE DIFFERENCE WAS THAT GFS WANTED TO BEGIN TRANSLATING THE WEST COAST TROUGH ACROSS THE NATION BEGINNING EARLY NEXT WEEK. THIS SEEMS UNREASONABLE DUE TO THE ESTABLISHED BLOCKING RIDGE IN THE EAST PACIFIC...WHICH SHOULD SLOW ANY EASTWARD PROGRESSION OF THE THE WEST COAST TROUGH. THEREFORE I HAVE LEANED TOWARDS THE IDEA THAT THE TROUGH WILL COME OUT IN BITS AND PIECES...AS SHOWN BY THE ECMWF. WITH THIS IN MIND...EXPECTATIONS ARE THAT WEAK RIDGING WILL MOVE IN ACROSS THE CENTRAL PLAINS LATE THIS WEEK...WITH A LEE SIDE LOW SPINNING UP IN WEST KANSAS AND NEBRASKA IN ADVANCE OF THE DIGGING WEST COAST TROUGH. THIS WILL LIFT A WARM FRONT BACK THROUGH NORTHERN MISSOURI FRIDAY AND SATURDAY...HELPING TEMPERATURES RANGE 10 OR MORE DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR. AS THE TROUGH DIGS INTO THE WEST COAST OVER THE WEEKEND IT IS THEN EXPECTED TO EJECT A SHORT WAVE THAT WILL ORGANIZE THE LEE SIDE LOW INTO A COLD FRONT DRAPED ACROSS THE MIDWEST. THIS FRONT WOULD THEN PUSH SOUTHEAST THROUGH MISSOURI SUNDAY/MONDAY. MOISTURE LOOKS A LITTLE MARGINAL AT THIS TIME...BUT WITH A FRONTAL BOUNDARY MOVING THROUGH SOME CHANCE THUNDERSTORM POPS LOOK REASONABLE FOR SUNDAY AND MONDAY. CUTTER && .EAX WATCHES/WARNINGS/ADVISORIES... KS...FLASH FLOOD WATCH TILL 6 AM FROM DONIPHAN SOUTH TO JOHNSON COUNTIES ALONG THE KS/MO BORDER. MO...FLASH FLOOD WATCH TILL 6 AM FOR AREAS FROM ANDREW COUNTY SOUTH TO CASS COUNTY...AND EAST TO RANDOLPH SOUTH TO COOPER.

HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 1242 PM CDT TUE MAY 18 2004 KSZ025-057-060-102>105-MOZ001>008-011>017-020>025-028>033-037>040- 043>046-053-054-191100- 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 ISOLATED THUNDERSTORMS WILL BE POSSIBLE THROUGH THE MID AFTERNOON HOURS ACROSS PORTIONS OF EAST CENTRAL KANSAS AND WEST CENTRAL MISSOURI. STORMS MAY BECOME MORE ORGANIZED DURING THE LATE AFTERNOON HOURS ALONG A BOUNDARY THAT IS EXPECTED TO SET UP ACROSS THE SOUTHERN PORTIONS OF THE KANSAS CITY METRO AREA...EAST TO AROUND BOONVILLE MISSOURI. STORMS LATE THIS AFTERNOON WILL HAVE THE POTENTIAL OF PRODUCING LARGE HAIL. IF THE STORMS CAN DEVELOP ENOUGH TO TAP INTO THE SURFACE WIND FIELDS EVEN AN ISOLATED TORNADO OR WIND DAMAGE CAN NOT BE RULED OUT. THE STORMS THIS EVENING SHOULD BUILD SOUTH OUT OF THE OUTLOOK AREA. THEN LATE TONIGHT AS THE BOUNDARY BEGINS TO LIFT NORTH AS A WARM FRONT ADDITIONAL THUNDERSTORM DEVELOPMENT MAY TAKE PLACE. AGAIN THE MAIN THREAT FOR THESE STORMS WOULD BE HAIL. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY WITH A VERY ACTIVE WEATHER PATTERN ACROSS THE CENTRAL PART OF THE COUNTRY...THUNDERSTORMS ARE FORECAST FOR SEVERAL PERIODS DURING THE EXTENDED OUTLOOK. FIRST ON WEDNESDAY MORNING...STORMS MAY BE LIFTING NORTH THROUGH THE NORTHERN HALF OF MISSOURI AND NORTHEAST KANSAS. IF NORTHERN MISSOURI DOES SEE THESE STORMS...THE ADDITIONAL HEAVY RAINFALL ON ALREADY SATURATED GROUND MAY LEAD TO FLOODING PROBLEMS. THESE STORMS MAY ALSO CONTAIN LARGE HAIL. BY LATER IN THE DAY...THE FRONT SHOULD BE FAR ENOUGH NORTH TO KEEP MOST OF THE THUNDERSTORM DEVELOPMENT NORTH OF MISSOURI. HOWEVER...IF STORMS CAN DEVELOP LATE IN THE DAY ON WEDNESDAY IN EXTREME NORTHERN MISSOURI...DAMAGING WINDS AND HAIL WOULD BE POSSIBLE. FURTHER OUT...ANOTHER FRONTAL BOUNDARY MOVING INTO THE AREA SATURDAY NIGHT AND SUNDAY WILL BRING MORE CHANCES OF THUNDERSTORMS...FIRST IN NORTHERN MISSOURI SATURDAY NIGHT...AND ACROSS THE ENTIRE OUTLOOK AREA SUNDAY AND SUNDAY NIGHT. THE BEST CHANCE OF SEVERE STORMS WILL BE WITH THE FRONT DURING THE DAY ON SUNDAY. THE NEXT CHANCE OF STORMS WILL BE MONDAY NIGHT WITH YET ANOTHER FRONTAL BOUNDARY. AGAIN SEVERE WEATHER MAY OCCUR WITH THIS FRONT. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED LATE THIS AFTERNOON AND EARLY EVENING IN AREAS SOUTH OF THE MISSOURI RIVER...LATE TONIGHT AND DURING THE MORNING ON WEDNESDAY ACROSS MAINLY NORTHWEST MISSOURI AND NORTHEAST KANSAS...AND POSSIBLE LATE IN THE DAY IN EXTREME NORTHERN MISSOURI ON WEDNESDAY. && THIS PRODUCT...ALONG WITH OTHER WEATHER...HYDROLOGIC AND CLIMATE INFORMATION...IS AVAILABLE ON THE WEB AT (LOWER CASE) HTTP://WWW.CRH.NOAA.GOV/EAX OR HTTP://WEATHER.GOV.
