NWS Kansas City, MO wrote its last area forecast discussion before the first event at Aug 26, 3:45 PM CST, 6 hours 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 445 PM CDT WED AUG 26 2003 SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ALONG HIGHWAY 36 ALONG AN AREA OF ENHANCED CONVERGENCE EVIDENT ON THE WIND PROFILER NETWORK AT 850MB. THE 12 ETA MODEL HAS DONE A GOOD JOB THUS FAR HANDLING THE INITIATION OF THIS ACTIVITY, BUT I BELIEVE THAT BY MID EVENING IT DRIVES THE CONVECTION TOO FAR SOUTH. WHILE COVERAGE SHOULD BE FAIRLY GOOD THIS EVENING, I DONT ANTICIPATE A LARGE COLD POOL TO DEVELOP. SO I WOULD EXPECT MOST OF THE CONVECTION TO REMAIN ALONG AND NORTH OF THE MISSOURI RIVER. MUCH OF THE CONVECTION SHOULD DIE DOWN BY LATE EVENING WITH THE LOSS OF PEAK HEATING, BUT A FEW SHOWERS AND STORMS MAY PERPETUATE IN AN ELEVATED UNSTABLE LAYER. THE ETA SUGGESTS A SHEAR AXIS AT 700MB FROM AROUND MARYVILLE MISSOURI TO BOONVILLE. AT THIS TIME ELEVATED CONVECTION IS LOW CONFIDENCE SO IVE ONLY INCLUDED AT 20 TO 25 PERCENT CHANCE THROUGH TOMORROW MORNING. BOTH THE ETA AND GFS SHIFT LOW LEVEL CONVERGENCE ABOUT 50 MILES FURTHER SOUTH TOMORROW. I DONT EXPECT SCATTERED CONVECTION TO DEVELOP UNTIL LATE AFTERNOON, SO TEMPERATURES WILL LIKELY EXCEED 100 DEGREES IN ALL BUT NORTHEAST AND NORTH CENTRAL MISSOURI TOMORROW. I HAVE EXTENDED HEAT ADVISORIES FROM MARYVILLE TO CHILLICOTHE TO BOONVILLE AND POINTS SOUTHWEST DUE TO THE HEAT EXPECTED TOMORROW. THE KANSAS CITY METRO HAS BEEN UPGRADED TO AN EXCESSIVE HEAT WARNING DUE TO THE DURATION OF HEAT AND URBAN HEAT ISLAND EFFECTS. STRONG COLD FRONT FORECAST TO MOVE THROUGH FORECAST AREA ON FRIDAY WITH SLOWER ETA MODEL PREFERRED. KEPT TEMPERATURES ABOVE NORMAL WITH THE CAVEAT THAT MORE CLOUDS AND/OR FASTER FRONTAL MOVEMENT WILL NECESSITATE LOWERING HIGH TEMPERATURES. RAISED RAIN CHANCES AS WELL DUE TO POOLING OF BOUNDARY LAYER MOISTURE AND SHORTWAVE MOVING THROUGH. ADDED POPS TO SATURDAY AS WELL AS MODELS ADVERTISE ANOTHER SHORTWAVE EMBEDDED IN ZONAL AND FASTER MID/UPPER LEVEL FLOW PROVIDES ELEVATED LIFT IN POST FRONTAL AIRMASS. HAVE ALSO LOWERED HIGH TEMPERATURES DUE TO EXTENSIVE CLOUD COVER AND RAIN. MJ 340 AM... AN AIRMASS VERY SIMILAR TO WHAT WE EXPERIENCED YESTERDAY...WITH MID LEVEL MOISTURE AND COOL TEMPERATURES PROVIDING FOR SUFFICIENT INSTABILITY...WILL REMAIN ACROSS THE AREA AND PROVIDE FOR PULSE DIURNALLY DRIVEN THUNDERSTORMS AGAIN TODAY. CONVECTIVE TEMPERATURES RIGHT AROUND 100 DEGREES WILL BE ATTAINABLE AND EXPECT INCREASED AREAL COVERAGE OF THUNDERSTORMS OVER YESTERDAY. WITH THE FIRST OF TWO SURFACE BOUNDARIES APPROACHING MISSOURI BY WEDNESDAY AND SHORTWAVE ENERGY FORECAST TO HANG AROUND THE FORECAST AREA...HAVE MADE FEW MODIFICATIONS TO THE PRECIPITATION CHANCES WEDNESDAY THROUGH OVERNIGHT FRIDAY. A MINOR BREAK IN TEMPERATURES WEDNESDAY MAY BE JUST ENOUGH TO KEEP BELOW HEAT ADVISORY CRITERIA ALTHOUGH WILL NEED TO CONTINUE TO MONITOR TRENDS. KEPT THE FORECAST DRY FROM SATURDAY ON AS MODELS CONTINUE TO DISAGREE ON HOW TO HANDLE THE UPPER TROUGH MOVEMENT. TEMPERATURES STILL LOOK TO MODERATE DOWNWARD BY THE WEEKEND TO MORE COMFORTABLE AND CLIMATOLOGICALLY NORMAL LEVELS. STOFLET 910 PM MON... DID SOME MINOR REVISION TO FORECASTS TO ADD ISOLATED STORMS IN PORTIONS OF NORTHERN MISSOURI AND NORTHEAST KANSAS WHERE THEY HAVE DEVELOPED IN VICINITY OF WEAK SHORT WAVES MOVING THROUGH EASTERN NEBRASKA AND IOWA. MESOETA SHOWS THIS ACTIVITY SHOULD BECOME MORE FOCUSED IN AREA OF STRUNG OUT VORTICITY ACROSS IOWA LATE TONIGHT...SO WILL PUT WORDING IN FORECASTS JUST THROUGH EARLY MORNING WITH ANTICIPATION OF ACTIVITY PULLING OUT OF AREA BY 3 AM.
