NWS Kansas City, MO wrote its last area forecast discussion before the first event at Jul 4, 2:30 PM CST, 10 hours 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 330 PM CDT SUN JUL 4 2004 .DISCUSSION... EARLY AFTERNOON SATELLITE IMAGERY AND UPPER AIR ANALYSIS INDICATE BROAD MEAN TROUGH ACROSS MUCH OF CONUS WITH NUMEROUS SHORTWAVE TROUGHS/VORTICITY FEATURES (SOME CONVECTIVELY INDUCED) EMBEDDED WITHIN FLOW. PRIMARY FEATURES OF INTEREST FOR THIS FORECAST PACKAGE ARE TROUGH ACROSS PACIFIC NORTHWEST/ROCKIES...AND SOUTHERN STREAM PERTURBATION CURRENTLY OVER NORTHERN NM. SUBSIDENCE IN WAKE OF EARLY MORNING MCS HAS ALLOWED FOR MOSTLY SUNNY SKIES ACROSS MUCH OF CWA THIS AFTERNOON. EARLY AFTERNOON SURFACE ANALYSIS INDICATES SURFACE TROUGH/WIND SHIFT LOCATED ACROSS NORTHERN MO...EXTENDING JUST NORTH OF THE I-70 CORRIDOR. FURTHER SOUTHWEST OLD OUTFLOW BOUNDARY FROM OVERNIGHT MCS LOCATED ACROSS NORTHERN OK INTO SOUTHWEST KS. A FEW SHOWERS/THUNDERSTORMS ARE LOCATED JUST NORTH OF THIS BOUNDARY...AND APPEAR TO BE ASSOCIATED WITH ISENTROPIC LIFT/ELEVATED MOISTURE RETURN. SOMEWHAT UNCERTAIN FORECAST REGARDING PRECIPITATION FOR THE NEXT COUPLE OF DAYS. WHAT IS CERTAIN IS THAT PACIFIC NORTHWEST/ROCKIES TROUGH WILL SLOWLY PROPAGATE ACROSS PLAINS MONDAY AND TUESDAY...RESULTING IN DEVELOPMENT OF SEVERAL CONVECTIVE SYSTEMS. HOW THESE SYSTEMS EVOLVE AND WHERE THEY TRACK REMAINS SOMEWHAT UNCERTAIN...THUS IT IS DIFFICULT TO NAIL DOWN PRECISE TIMING/PLACEMENT OF PRECIPITATION CHANCES. AS A RESULT HAVE KEPT POPS IN CHANCE CATEGORY THROUGH TUESDAY. FOR THIS EVENING INTO THE OVERNIGHT HOURS...ISOLATED CONVECTION ACROSS SOUTH CENTRAL KS MAY MAKE IT INTO FAR SOUTHWEST MO EARLY THIS EVENING...AND WILL INCLUDE A LOW CHANCE POP. OTHERWISE CONVECTION CURRENTLY FIRING OVER HIGH PLAINS...AS WELL AS ANTICIPATED CONVECTION ALONG DRYLINE FROM SW KS INTO TX PANHANDLE AHEAD OF NM VORT MAX WILL LIKELY CONGEAL INTO ONE OR MORE MCSS THIS EVENING...WITH CORFIDI VECTORS INDICATING A MEAN SOUTHEASTWARD MOTION. EXPECT DOMINANT MCS TO DEVELOP OVER SOUTHWEST/WEST CENTRAL KS INITIALLY TRACKING EASTWARD INTO CENTRAL KS ALONG NOSE OF STRENGTHENING LOW LEVEL JET...THEN SOUTHEASTWARD INTO NORTHEAST OK/FAR SOUTHWEST MO LATE TONIGHT AS LOW LEVEL JET VEERS. CONVECTIVE EVOLUTION FURTHER NORTH ACROSS NORTHERN KS/NE REMAINS MORE UNCERTAIN AND DEPENDENT ON AVAILABLE INFLOW INTO SYSTEM. HAVE KEPT HIGHEST POPS (40S) ACROSS SOUTHWEST COUNTIES AFTER MIDNIGHT...WITH SLIGHTLY LOWER POPS FURTHER NORTH. WOULDNT BE TOTALLY SURPRISED TO SEE MCS TAKE MORE OF A SOUTHERN TRACK (MUCH LIKE LAST NIGHT) AND MISS CWA ENTIRELY. LARGE SCALE LIFT ASSOCIATED WITH EJECTING TROUGH WILL SPREAD ACROSS THE AREA MONDAY INTO TUESDAY. BEST PRECIPITATION CHANCES WILL AGAIN BE TIED TO PLACEMENT OF SURFACE FEATURES...AND WILL HAVE TO WAIT FOR TONIGHTS CONVECTION TO PLAY OUT...SO FOR NOW HAVE JUST RETAINED CHANCE POPS ACROSS CWA...WITH SLIGHTLY HIGHER POPS ACROSS NORTH IN PROXIMITY TO BETTER LARGE SCALE LIFT. SURFACE FRONT SHOULD PUSH THOUGH AREA BY TUESDAY EVENING ENDING PRECIPITATION THREAT. IN TERMS OF TEMPERATURES...HAVE GENERALLY STAYED CLOSE TO PERSISTENCE WITH DAYTIME TEMPS RUNNING CLOSE TO SLIGHTLY BELOW AVERAGE. SEAMAN AFTER THE COLD FRONT MOVES THROUGH AT THE BEGINNING OF THE WEEK...A COUPLE OF DAYS IN THE MIDDLE OF THE WEEK WILL FEATURE HIGH PRESSURE BEFORE WE SEE RETURN FLOW. BY THE END OF THE WEEK...AN OPEN UPPER TROUGH MOVES ACROSS THE NORTHERN PLAINS. MEANWHILE A SURFACE FRONT PLANTS ITSELF FROM SOUTHWEST KANSAS UP TO CENTRAL IOWA BY FRIDAY. THE CHALLENGE IN THE EXTENDED FORECAST IS TO FIGURE WHEN THIS NEXT FRONT WILL AFFECT THE FORECAST AREA. THE ECMWF IS QUICK TO MOVE THIS FRONT THROUGH BY SATURDAY NIGHT...WHILE THE GFS HANGS ONTO IT AND DOESNT GET IT ACROSS NORTHWEST MISSOURI UNTIL SUNDAY NIGHT. HAVE PLACED CHANCE POPS IN THE FRIDAY NIGHT THROUGH SAT NIGHT TIMEFRAME WITH SLIGHTS AFTER THAT...WHICH IS MAINLY IN LINE WITH THE ECMWF. HOWEVER WITH UPPER LOW SO FAR NORTH AND LITTLE TEMPERATURE GRADIENT TO THE NORTHERN PLAINS...IT MAY BE LONGER BEFORE THE FRONT GETS HERE AS THE GFS DEPICTS. TEMPERATURES WILL BE BACK TO AROUND NORMAL READINGS IN THE UPPER 80S. && .PREV DISCUSSION... 624 AM... QUICK ADJUSTMENT TO THIS MORNINGS FORECAST FOR THE CONVECTION. THE ACTIVITY ACROSS NORTHERN MISSOURI HAS FINALLY BEEN QUASHED BY THE SUBSIDENCE BEHIND THE LOW LIFTING INTO THE GREAT LAKES. FARTHER SOUTH...THE MCSS SOUTHERN END HAS DEVELOPED AN INTENSE COMPLEX THAT IS SINKING THROUGH SOUTHEAST KANSAS AND SOUTHWEST MISSOURI. SO BASED ON CURRENT RADAR TRENDS...I HAVE STRIPPED MORNING POPS OUT OF MOST OF THE CWA. ONLY KEEPING SOME SMALL CHANCE POPS ACROSS THE SOUTHERN TIER OF COUNTIES...AND THOSE ONLY TILL 9 AM. CUTTER && .PREV DISCUSSION... 317 AM SUN... A MESSY QUASI-ZONAL PATTERN CONTINUES TO DOMINATE THE CONUS THIS MORNING. THE WEAK UPPER LEVEL LOW...THAT HAD BEEN CONTROLLING THE WEATHER ACROSS KANSAS AND MISSOURI...HAS LIFTED TOWARDS THE GREAT LAKES LEAVING WEAK RIDGING AND SUBSIDENCE IN ITS WAKE. FARTHER WEST A SERIES OF SHORTWAVES...THAT WILL KEEP OUR WEATHER ACTIVE...ARE STACKED UP IN THE WESTERLIES ACROSS THE PACIFIC NORTHWEST...ROCKY MOUNTAINS...AND HIGH PLAINS. THE CLOSEST WAVE...MOVING THROUGH NEBRASKA THIS MORNING...HAS SPARKED A MCS WHICH MIGHT LEAVE SOME THUNDERSTORMS FLOATING AROUND ACROSS EASTERN KANSAS AND NORTHERN MISSOURI AFTER DAYBREAK. THE NORTH SOUTH ORIENTED LINE...CURRENTLY MOVING THROUGH NORTHERN MISSOURI... SHOULD GRADUALLY DIE OFF AS IT MOVES EAST INTO THE MORE STABLE AIRMASS BEHIND THE EXITING LOW. THE SOUTH END OF THE LINE IN CENTRAL KANSAS WILL CONTINUE TO FIRE ON THE SURFACE BOUNDARY... SPREADING SOUTH INTO SOUTH CENTRAL KANSAS AND ALLOWING THUNDERSTORMS TO PROPAGATE THROUGH EAST KANSAS AND POTENTIALLY INTO WEST CENTRAL MISSOURI. I HAVE LEFT A GOING CHANCE OF THUNDER ACROSS MOST OF THE CWA THROUGH MID MORNING TO COVER ANY RESIDUAL STORMS ACROSS THE NORTH HALF OF THE CWA...AND ANYTHING THAT HAS NOT QUITE EXITED THE REGION IN THE SOUTHERN HALF. THE NEXT SHORTWAVE..CURRENTLY LOCATED IN THE GREAT BASIN...IS PROGGED TO SLIDE INTO KANSAS THIS AFTERNOON. WARM AIR ADVECTION AHEAD OF THIS WAVE WILL HAVE AN OPPORTUNITY TO INTERACT WITH ANY LEFTOVER SURFACE BOUNDARIES TO POP OFF MORE CONVECTION LATE THIS AFTERNOON/EARLY THIS EVENING. WITH CAPE VALUES STILL PROGGED TO RANGE UPWARDS OF 5000+ J/KG...AND 0-6 KM BULK SHEAR RANGING FROM 25-35 KTS...ANY STORMS THAT DO GET GOING WILL HAVE THE POTENTIAL FOR TO PRODUCE SEVERE HAIL AND DAMAGING WINDS. HOWEVER...WITH THE PROGRESSIVE NATURE OF THIS MORNINGS MCS...MY THOUGHTS ARE THAT ANY BOUNDARIES THAT COULD FOCUS INITIATION SHOULD BE TO THE EAST OR SOUTH OF THE CWA FOR MOST OF THE DAY. THEREFORE I HAVE PUSHED BACK OUR ONSET OF OUR THUNDERSTORM CHANCES INTO THE EVENING HOURS. HEAVY PRECIP COULD OCCUR WITH ANY OF THE ACTIVITY WE GET OVERNIGHT. BUT...COVERAGE LOOKS TO BE PROBLEMATIC EVERYWHERE BUT EAST CENTRAL KANSAS AND WEST CENTRAL MISSOURI...WHICH IS WHERE FLASH FLOOD GUIDANCE VALUES HIGHEST. SO...NO FLASH FLOOD WATCH IS CURRENTLY ANTICIPATED. FOR MONDAY INTO TUESDAY...A MORE WELL DEFINED TROUGH WILL MOVE THROUGH THE NORTHERN HALF OF THE PLAINS. THIS WAVE LOOKS TO FOCUS CONVECTION ALONG A WARM FRONT IN SOUTHERN IOWA...BUT ANY PREVIOUS CONVECTION COULD LEAVE ENOUGH BOUNDARIES AROUND TO CONFUSE THE ISSUE. SO...I WILL KEEP A CHANCE OF THUNDER EVERYWHERE FOR MONDAY THROUGH MONDAY NIGHT...BUT THE HIGHEST POPS WILL BE ALONG THE IOWA BORDER. FOR TUESDAY...I SHIFT THE THUNDER CHANCES EAST THROUGH THE CWA AS THE TROUGH PUSHES A COLD FRONT THROUGH. OTHERWISE...FOR TUESDAY AND WEDNESDAY I DROPPED TEMPS A CATEGORY AS COOL AIR WORKS ITS WAY SOUTH IN THE BASE OF THE TROUGH MOVING THROUGH THE NORTHERN PLAINS.
