Area forecast discussion, Jun 25, 1:37 PM CDT, 1 hour before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 137 PM CDT WED JUN 25 2003 UPDATED FORECASTS TO ADD A FLOOD WATCH FOR THIS AFTERNOON AND EVENING FOR THE KANSAS CITY METRO AREA. FLASH FLOOD GUIDANCE ON THE LOW SIDE FOR PORTIONS OF THE METRO AREA...EXPECIALLY ON THE KANSAS SIDE. ALTHOUGH STORMS SHOULD MOVE THROUGH PRETTY RAPIDLY WITH FRONT PASSING THROUGH AREA IN THE 00Z TO 01Z TIMEFRAME...THINK STORMS WILL CONTAIN VERY HEAVY RAINS THAT MAY CAUSE LOCALIZED FLOODING...ESPECIALLY IN THOSE PLACES FAVORED FOR COLLECTING WATER IN HEAVY DOWNPOURS. PC 1208 PM... WILL DO SOME MINOR REWORDING TO FORECASTS TO ADD MENTION OF WINDS AND HEAVY RAIN TO THUNDERSTORM POTENTIAL THIS AFTERNOON TONIGHT. ALSO WILL RAISE POPS SOME GIVEN THE FACT THAT FRONT IS LIGHTING UP AND ONGOING CONVECTION IN WARM SECTOR AHEAD OF FRONT. MESOETA SEEMS TO HAVE THE BEST HANDLE ON TIMING OF THE FRONT WHICH SHOULD BE NOT BE GETTING TO THE KANSAS CITY AREA UNTIL AFTER 00Z. PC 329 AM... THE FOCUS OF THIS MORNINGS FORECAST IS CENTERED ON THE EXPECTED THUNDERSTORM ACTIVITY TODAY AND TONIGHT. ALL THE MODELS ARE IN GOOD AGREEMENT ON THE PROGRESSION OF THE UPPER LEVEL TROUGH AND ACCOMPANYING COLD FRONT AS IT PUSHES ITS WAY THROUGH THE PLAINS STATES TODAY. SATELLITE...SURFACE AND RADAR DATA BACKUP THE CURRENT ANALYSIS OF THE MODELS. RADAR TRENDS PLACE THE FIRST LINES OF CURRENT ONGOING CONVECTION IN THE EXTREME NORTHWEST CORNER OF MISSOURI AROUND 14Z. NOT ENTIRELY SURE THAT THE CONVECTION WILL HOLD TOGETHER THAT LONG. THE RADAR RETURNS ARE STARTING TO LOOK A LITTLE RAGGED. THE STORMS APPEAR TO BE HAVING A HARD TIME MAINTAINING COMPOSURE ALONG THE SOUTHERN END AS LOW LEVEL WINDS CONTINUE TO VEER UNDER THE INFLUENCE OF THE APPROACHING TROUGH. HENCE...I HAVE CONTINUED WITH ONLY CHANCE POPS IN THE NORTHWEST CORNER OF MISSOURI FOR THIS MORNING. THE COLD FRONT SHOULD MOVE INTO MISSOURI IN THE LATE AFTERNOON EARLY EVENING HOURS. EXPECT CONVECTION TO FIRE IN EAST KANSAS/WEST MISSOURI SOMETIME BEFORE THAT IN THE NOON TO EARLY AFTERNOON TIME FRAME. A COMBINATION OF SURFACE HEATING AND UPPER LEVEL DYNAMICS SHOULD HELP KICK THINGS OFF. I WENT AHEAD AND SLIGHTLY EXPENDED THE LIKELY POPS FOR THE MID AFTERNOON HOURS AS THERE SEEMS TO BE THE POTENTIAL FOR A SHORT WAVE...CURRENTLY COMING OUT OF TEXAS...KICKING OFF ADDITIONAL CONVECTION AHEAD OF THE FRONT. ADJUSTED THIS AFTERNOONS HIGH TEMPS DOWN A COUPLE OF DEGREES AS CLOUD COVER OFF THE STORMS TO OUR NORTHWEST AND ADVECTED MOISTURE FROM THE SOUTH WILL CONSPIRE AGAINST US. HOWEVER...GOING TEMPS ARE STILL WARMER THEN THE MAV OR MET GUIDANCE NUMBERS WHICH CAME IN WITH NUMBERS IN THE LOW TO MID 80S FOR MUCH EAST KANSAS AND MISSOURI TODAY. CUTTER 335 PM... MAIN FORECAST CONCERNS IN THE SHORTER TERM ARE WITH CHANCES OF THUNDERSTORMS THIS EVENING...AND THEN FOCUS TURNS TO COLD FRONT ON WEDNESDAY. REGARDING THIS EVENING...CURRENT TRENDS SHOW MOISTURE AXIS RUNNING THROUGH FLINT HILLS INTO AREA BETWEEN KANSAS CITY AND OMAHA. ISOLATE STORMS HAVE TRIED TO DEVELOP BUT STRUGGLING WITH A BIT TO GET GOING WITH LACK OF SURFACE CONVERGENCE OR AN UPPER WAVE TO FOCUS ORGANIZATION. WILL KEEP ISOLATED STORMS MENTIONED IN NORTHEAST KANSAS AND NORTHWEST MISSOURI FOR THE EARLY EVENING HOURS...WHICH IS UNDER THE MOISTURE AXIS...AND JUST GO SLIGHT CHANCES FURTHER SOUTH AND EAST. FOR WEDNESDAY...MODELS LOOK ON TRACK WITH SURFACE FRONT CURRENTLY SITUATED OVER NORTHWEST NEBRASKA. FRONT ASSOCIATED WITH STRONG UPPER WAVE MOVING OUT OF THE ROCKIES. QUITE A TEMPERATURES CONTRAST WITH THIS FRONT. WILL START TO TREND DOWN TEMPS ON THURSDAY AFTER ITS PASSAGE. WITH CLOUDS INCREASING IN VERY MOIST AIR AHEAD OF FRONT SHOULD HELP KEEP TEMPS IN CHECK A BIT...BUT ALSO CONCERNED WITH SOME COMPRESSIONAL WARMING IN ADVANCE OF FRONT. WILL GO ABOVE GUIDANCE VALUES AND KEEP PRETTY MUCH WHAT WE HAD GOING IN FORECAST. WITH VIGOROUS FRONT...AND DECENT SHEAR AND MOISTURE...LOOKS LIKE SEVERE WEATHER FOR THE WEDNESDAY AFTERNOON AND EVENING TIMEFRAME. FRONT WILL BLOW THROUGH PRETTY RAPIDLY WEDNESDAY NIGHT...SO WILL PULL CHANCES OF RAIN OUT OF THURSDAY FORECAST. PC IN THE LONGER RANGE...AS THE UPPER LEVEL TROUGH AXIS SHIFTS TOWARD THE GREAT LAKES REGION...KANSAS AND MISSOURI COME UNDER THE INFLUENCE OF WEAK NORTHWEST FLOW BY FRIDAY ON THE EASTERN SIDE OF A SURFACE HIGH. A SECONDARY UPPER LOW DEVELOPS FRIDAY NIGHT OVER MANITOBA HOWEVER THE ASSOCIATED ENERGY REMAINS TO THE NORTH OF NORTHERN IOWA IN ASSOCIATION WITH A 90 KT UPPER LEVEL JET. THE MODELS ARE TRENDING TOWARD A LESS AMPLIFIED UPPER LEVEL PATTERN AND IF THAT IS THE CASE...THE PRECIPITATION SHOULD REMAIN TO THE NORTH OF MISSOURI. THE WARMEST TEMPERATURES IN THE EXTENDED LOOK TO BE ON SATURDAY IN THE UPPER 80S WITH STRONG WARM AIR ADVECTION. A WEAK SURFACE FRONT MOVES INTO NORTHERN MISSOURI AND EXTREME NORTHEAST KANSAS SATURDAY NIGHT. MOISTURE RETURN INDICATED BY DEWPOINTS IN THE 60 TO 65 DEGREE RANGE COMBINED WITH ANY LIFT ALONG THE SURFACE BOUNDARY IS THE REASON FOR INTRODUCING PRECIPITATION CHANCES SATURDAY NIGHT. NEARLY ZONAL FLOW IS ESTABLISHED OVER THE KANSAS-MISSOURI REGION BY SUNDAY. AS AN UPPER LOW DIGS ITS WAY ACROSS THE WESTERN CANADIAN PROVINCES...RIDGING TAKES PLACE OVER THE NORTH CENTRAL U.S. KEEPING MONDAY INTO TUESDAY DRY. STOFLET 1215 PM... BASED ON CURRENT DEVELOPMENT SHOWING UP ON WICHITA RADAR...AND SPC CONCERNS ABOUT RAPID DEVELOPMENT OF STORMS BETWEEN OMA AND MCI...WILL INTRODUCE THUNDERSTORM CHANCES INTO WESTERN FORECAST AREA FOR THIS AFTERNOON AND EARLY EVENING PERIOD.
