NWS Kansas City, MO wrote its last area forecast discussion before the first event at Aug 20, 12:10 PM CST, 2 hours 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 110 PM CDT SAT AUG 20 2005 .DISCUSSION... UPDATING FORECAST TO LOWER HIGH TEMPERATURES ACROSS SOUTHWEST 1/4 OF CWA WHERE CIRRUS BLOWOFF FROM SOUTHERN KS STORMS CONTINUES TO SPREAD NORTHEAST. SO HAVE ALSO INCREASED CLOUD COVER OVER ALL BUT NORTHWEST MO. TRUE COLD FRONT WILL NOT COME THROUGH TILL SUNDAY MORNING SO UPPING DEWPOINTS THROUGH TONIGHT. MAY NEED TO CONSIDER ADDING FOG. MJ && .PREV DISCUSSION... 330 AM... THE SHORTWAVE IS BEGINNING TO PICK UP SOME MOMENTUM AS EVIDENT IN PROFILER NETWORK. SO THE RAIN SHOULD BE ENDING DURING THE MORNING HOURS. HOWEVER THE SURFACE COLD FRONT WILL MOVE THROUGH THE REGION VERY SLOWLY TODAY...AND MAY NOT ACTUALLY MAKE IT ALL THE WAY TO SOUTHERN MISSOURI. CONVERGENCE ALONG THE FRONT WILL BE VERY WEAK AND AM ONLY EXPECTING SCATTERED CONVECTION(IF ANY) TO DEVELOP THIS AFTERNOON ACROSS CENTRAL MISSOURI. A STRONGER COLD FRONT WILL MOVE SOUTH ACROSS THE REGION TONIGHT AS ANOTHER SHORTWAVE ROTATES AROUND A POTENT LOW PRESSURE SYSTEM MOVING ACROSS SOUTHERN CANADA. AM NOT EXPECTING MUCH PRECIP ASSOCIATED WITH THIS FRONT CONSIDERING THE AMOUNT OF DRY AIR. HOWEVER WILL LEAVE IN SLIGHT CHANCE POPS ACROSS FAR NORTHERN MISSOURI AS THE FRONT WILL BE MOVING ACROSS THAT AREA NEAR THE TIME OF PEAK HEATING. ANOTHER POSITIVE FACTOR AS FAR AS PRECIP GOES...THAT AREA IS UNDER THE ENTRANCE REGION OF A WEAK 300MB JET MAX. THE GFS PROGS A STRONG VORT MAX TO MOVE ACROSS THAT AREA AS WELL...HOWEVER THAT LOOKS LIKE CONVECTIVE FEEDBACK AND HAVE THROWN THAT OUT. IF THE MODELS ARE CORRECT AND 850MB TEMPS IN THE 12-15C RANGE MOVE INTO THE REGION. AREA SHOULD SEE HIGHS ONLY IN THE UPPER 70S TO MID 80S FROM SUNDAY THROUGH TUESDAY...WITH MONDAY AND TUESDAY BEING THE COOLEST DAYS. ETA PROGS RETURN FLOW TO BEGIN TUESDAY NIGHT ACROSS THE NORTHWEST CORNER OF MISSOURI. HOWEVER THE GFS IS MUCH SLOWER...WITH A MORE AMPLIFIED RIDGE DEVELOPING OVER THE CENTRAL STATES. HAVE LEANED TOWARD THE GFS SOLUTION AND CONTINUED THE DRY FORECAST THROUGH MID WEEK PENDING MORE CONSISTENT MODEL RUNS. NRR && .PREV DISCUSSION... 929 PM FRI... OUTFLOW HAS PUSHED WELL AHEAD OF THE LINE OF THUNDERSTORMS. THIS SUGGESTS THAT THE STORMS WILL MAINTAIN AN OVERALL WEAKENING TREND THROUGH THE NIGHT. ALTHOUGH THERE WILL CONTINUE TO BE AN ISOLATED THREAT FOR DAMAGING WIND GUSTS. THEREFORE THE SEVERE THUNDERSTORM WATCH WILL LIKELY BE ALLOWED TO EXPIRE AT 10PM. TIMING THE END OF THE PRECIP OVERNIGHT INTO SATURDAY WILL BE DIFFICULT. SO FAR HAVE NOT SEEN MUCH OF A PUSH ALONG THE COLD FRONT. SUSPECT THE SHOWERS AND THUNDERSTORMS WILL CONTINUE WELL INTO SATURDAY...ESPECIALLY ACROSS CENTRAL MISSOURI...AS 850MB WINDS RUN NEARLY PARALLEL TO THE SURFACE/850MB BOUNDARIES. WILL THEREFORE ALLOW THE FLASH FLOOD WATCH TO CONTINUE. NRR 355 PM FRI... SEVERE THUNDERSTORMS AND FLASH FLOODING HIGHLIGHT THE FORECAST CONCERNS TONIGHT. OUTFLOW BOUNDARY FROM EARLIER KS CONVECTION HAS IGNITED FROM SOUTHWEST OF TOP THROUGH MCI. AIRMASS VERY UNSTABLE WITH HIGH PRECIPITABLE WATER VALUES COVERING ENTIRE CWA. 0-6KM BULK SHEAR VALUES SUPPORT POTENTIAL FOR A FEW INITIAL SUPERCELLS. DUE TO RECENT HEAVY RAINS OVER THE PAST 2 DAYS...DEGREE OF INSTABILITY... AVAILABLE LOW LEVEL MOISTURE AND PLUME OF SUBTROPICAL MOISTURE IT IS PRUDENT TO ISSUE FLASH FLOOD WATCH FOR THE ENTIRE CWA FOR ALL OF TONIGHT. HAVE HIT QPF GRIDS RATHER HARD WITH MANY LOCATIONS LIKELY TO SEE IN EXCESS OF AN INCH OF RAIN. APPROACHING COLD FRONT ORIENTED NORTH/SOUTH THROUGH EASTERN NEBRASKA AND CENTRAL KS WILL MARCH EAST-SOUTHEAST TONIGHT WITH ADDITIONAL CONVECTION FORMING ALONG IT. THUS SOME AREAS WILL SEE SEVERAL ROUNDS OF STORMS THROUGH 12Z SATURDAY. MINIMAL COOLING BEHIND THIS FRONT AND EXPECT TEMPERATURES TO WARM BACK UP TO SEASONAL VALUES ONCE THE SUN COMES OUT. SOUTHERN CWA WILL BE SLOWEST TO BREAK OUT OF CLOUDS AND MAY BE A BIT OVERLY OPTIMISTIC ON MAX TEMPERATURES. WILL MAINTAIN CHANCE POPS OVER SOUTHERN THIRD OF CWA FOR AT LEAST THE MORNING HOURS. FRONTAL BOUNDARY APPEARS TO HANG UP OVER SOUTHERN MO AND PLUME OF AFOREMENTIONED SUBTROPICAL MOISTURE BENDS EAST ACROSS SOUTHERN HALF OF MO. WEAK VORTICITY MAXIMA COULD EASILY BE EMBEDDED WITHIN THIS MOISTURE PLUME AND BE ENOUGH FOR WIDELY SCATTERED NUISANCE CONVECTION. HAVE ALSO ADDED LOW CHANCE POPS ACROSS NORTHWEST CORNER OF MO FOR SATURDAY EVENING AS SECONDARY/850MB FRONT DROPS SOUTHEAST. MAY BE ENOUGH RESIDUAL MOISTURE FOR SCATTERED STORMS TO FORM ALONG THE 850MB THETAE AXIS IN THE LATE AFTERNOON AND CONTINUE INTO NORTHWEST MO EARLY IN THE EVENING. MJ BY SUNDAY...THE SURFACE FRONT IS WELL PAST OUR CWA. A CURSORY LOOK TO THE MODELS AND GUIDANCE WOULD SAY TEMPS BACK TO NEAR NORMAL AND ZERO POPS. HOWEVER WE HAVE SOME CONCERN WITH THE H8 FRONT THAT IS STILL ACROSS OUR AREA SUNDAY MORNING. A SMALL POSSIBILITY THAT WE WILL SEE SOME SHOWER DEVELOPMENT ON THIS. THE GFS SHOWS A LITTLE MID LEVEL MOISTURE. WILL TREND ON THE CONSERVATIVE SIDE BY ADDING A FEW MORE CLOUDS AND KEEPING TEMPS JUST A LITTLE LOWER. AT THE BEGINNING OF THE WEEK...THE UPPER LEVEL RIDGE IS TO OUR WEST. AN UPPER LEVEL LOW MOVES ONTO THE PACIFIC COAST BY THE MIDDLE OF THE WEEK...ALTHOUGH THE TIMING OF THAT HAS BEEN CHANGING FROM RUN TO RUN. WHILE THIS UPPER LOW WOBBLES AROUND...A SURFACE FRONT GETS HUNG UP IN THE HIGH PLAINS. TIMING ON THIS ITEM HEADING EAST HAS BEEN UNCERTAIN THE PAST SEVERAL RUNS. WITHOUT A STRONG PUSH...THE FRONT WILL LIKELY TAKE ITS TIME REACHING US. GFS MAY BE HINTING AT PHASING THIS LOW WITH THE LOW NEAR THE GREAT LAKES ASSOCIATED WITH THE UPPER LOW. LATEST RUNS HAVE NOT AGREED ON TIMING...BUT GENERAL CONSENSUS HAS BEEN TO PUSH FROPA BACK UNTIL FRIDAY NIGHT (DAY7)... SIMILAR TO THE GFS/EC. TEMPERATURES SHOW A WARMING TREND THROUGH THE WEEK WITH THE WARMEST READINGS THU/FRI IN THE PREFRONTAL ENVIRONMENT. 27 && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE MO...NONE WFO EAX
