AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 215 PM CDT WED SEP 15 2004 .DISCUSSION... THE WEAK COLD FRONT WAS LOCATED NEAR INTERSTATE 35 THIS AFTERNOON WITH THE SHORTWAVE NOTICED EARLIER IN THE CENTRAL PLAINS HAVING SHIFTED QUICKLY NORTHEAST INTO MINNESOTA. A BROKEN BAND OF SHOWERS AND THUNDERSTORMS CONTINUE AHEAD OF THE FRONT AS THE FRONT PROGRESSES SLOWLY SOUTHEAST. WEAK HIGH PRESSURE SETTLING SOUTHEAST FROM THE NORTHERN PLAINS WILL CONTINUE TO PUSH THE FRONT THROUGH THE CWA THIS EVENING. ALTHOUGH SCT SHOWERS AND THUNDERSTORMS WILL CONTINUE ALONG THE FRONT THIS AFTERNOON AND THIS EVENING...DO NOT EXPECT ANY SEVERE ACTIVITY DUE TO LIMITED AFTERNOON HEATING IN ADVANCE OF THE FRONT. THE PRECIPITATION WILL END IN THE SE CWA THIS EVENING WITH CLOUD COVER GRADUALLY THINNING FROM THE NW TO SE. CLOUD COVER MAY LINGER IN THE SRN ZONES UNTIL VERY LATE TONIGHT DUE TO THE SLOW MOVEMENT OF THE FRONT ACROSS SOUTHERN MISSOURI. OTHERWISE...AN UPPER RIDGE WILL BUILD INTO THE CENTRAL PLAINS THROUGH FRIDAY. THE CIRCULATION AROUND IVAN AND THE HIGH PRESSURE RIDGE EXTENDING FROM MISSOURI TO THE GREAT LAKES WILL KEEP THE AREA UNDER EAST TO NORTHEAST LOW LEVEL FLOW THROUGH FRIDAY. PREFER COOLER MAV GUIDANCE IN THIS REGIME. DB AN AMPLIFYING UPPER TROUGH WILL DEVELOP OVER THE WESTERN CONUS THIS WEEKEND...WITH HURRICANE IVAN TO MEANDER WITHIN THE UPPER RIDGE ACROSS THE APPALACHIANS. THE 00Z GFS HAS COME IN LINE WITH YESTERDAYS THINKING WITH A SLOWER PROGRESSION OF THE AMPLIFIED TROUGH TOWARD THE PLAINS. THE SLOWER TROUGH WILL KEEP THE FORECAST AREA BENEATH UPPER RIDGING OVER THE WEEKEND INTO THE EARLY WORK WEEK...RESULTING IN TEMPERATURES WELL ABOVE NORMAL. A COLD FRONT IS THEN FORECAST TO MOVE ACROSS THE FORECAST AREA TUESDAY NIGHT INTO WEDNESDAY. HAVE INSERTED LOW CHANCES FOR SHOWERS AND THUNDERSTORMS DURING THIS TIME FRAME ALTHOUGH TIMING AND STRENGTH OF THE FRONT REMAIN IN QUESTION. && .PREV DISCUSSION... 155 AM... EARLY MORNING SATELLITE IMAGERY AND UPPER AIR ANALYSIS INDICATE MEAN LONGWAVE TROUGH AXIS LOCATED ALONG CENTRAL ROCKIES WITH SEVERAL SHORTWAVE FEATURES ROTATING THROUGH CYCLONIC FLOW. SHORTWAVE FEATURES EXPECTED TO INFLUENCE FORECAST AREA INCLUDE WEAK SHORTWAVE TROUGH CURRENTLY ACROSS EXTREME EASTERN KANSAS...WHICH COMBINED WITH ISENTROPIC LIFT ALONG 310K SURFACE ASSOCIATED WITH 40-50KT LOW LEVEL JET HAS ALLOWED AREA OF ACCAS TO RAPIDLY DEVELOP ACROSS MUCH OF NORTHERN MO. FURTHER WEST SHORTWAVE TROUGH WHICH WILL AFFECT AREA TODAY CURRENTLY LOCATED OVER NORTHWEST CO. SURFACE ANALYSIS INDICATED COLD FRONT CURRENTLY LOCATED FROM NORTHERN IA BACK INTO NORTH CENTRAL KS. LARGE AREA OF CONVECTION IN PROGRESS ALONG/BEHIND THIS BOUNDARY ACROSS CENTRAL NE/NORTHWEST KS. EXPECT LARGE CONVECTIVE COMPLEX TO CONTINUE DEVELOPING EASTWARD THROUGH THE OVERNIGHT HOURS...REACHING NORTHWEST MO TOWARDS DAYBREAK. ADDITIONALLY...CANT RULE OUT CHANCE OF ISOLATED/WIDELY SCATTERED SHOWERS THROUGH THE OVERNIGHT HOURS AHEAD OF THIS COMPLEX IN AFOREMENTIONED REGION OF ISENTROPIC LIFT. CO SHORTWAVE TO RAPIDLY LIFT ACROSS CENTRAL PLAINS INTO UPPER MS VALLEY REGION TODAY...WITH BEST LIFT SPREADING ACROSS EXTREME NORTHEAST KS/NORTHERN MO DURING THE MORNING HOURS. WILL KEEP HIGHEST POPS ALONG/WEST OF A KC TO KIRKSVILLE LINE. PRECIPITATION DURING THE AFTERNOON HOURS ALONG ADVANCING COLD FRONT APPEARS A LITTLE MORE UNCERTAIN...AS MAIN SYNOPTIC LIFT ASSOCIATED WITH CO SHORTWAVE SHIFTS NORTHEAST OF AREA. ETA MODEL HAS SLOWED TIMING OF FRONT CONSIDERABLY...NOW PROGGING FRONT TO STAY NORTH/WEST OF KC UNTIL THIS EVENING...WHILE GFS IS MORE PROGRESSIVE WITH FRONT. ALTHOUGH FAIRLY POOR MID LEVEL LAPSE RATES WILL LIMIT DEGREE OF INSTABILITY...IT STILL APPEARS SBCAPE VALUES WILL RANGE IN THE 1000-1500 J/KG THIS AFTERNOON ALONG FRONTAL BOUNDARY. WILL RETAIN AFTERNOON POPS ACROSS ALL BUT NW CORNER OF MO...THEN INCLUDE CHANCE POPS DURING EVENING HOURS ACROSS SOUTHEASTERN CWA TO ACCOUNT FOR SLOWER TIMING. TEMPERATURES TODAY WILL BE TRICKY...PARTICULARLY ACROSS NORTHERN MO WHERE DEGREE OF CLOUD COVER AND EXTEND/DURATION OF PRECIPITATION WILL DETERMINE WHETHER TEMPS ARE ABLE TO RECOVER THIS AFTERNOON. HAVE TRENDED TEMPS FROM UPPER 70S ACROSS NORTHWEST MO TO MID 80S ACROSS FAR SOUTHERN CWA. SEAMAN && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. WFO EAX
