NWS Kansas City, MO wrote its last area forecast discussion before the first event at Jul 25, 2:09 PM CST, 3 hours 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 309 PM CDT SUN JUL 25 2004 .DISCUSSION... NOT MUCH GOING ON IN THE SHORT TERM PORTION OF THE FORECAST. UNSEASONABLY COOL AIRMASS CONTINUES TO SETTLE IN OVER AREA...WITH POSITIVELY TILTED UPPER LEVEL TROUGH SWINGING FROM NEBRASKA INTO IOWA AND MISSOURI TONIGHT. THIS LOW DEEPENS A BIT AS IT TRACKS INTO AREA...BUT WITH LIMITED MOISTURE TO WORK WITH AND ONLY A LITTLE ELEVATED LIFT...NOT EXPECTING TO SEE ANY SHOWERS DEVELOPING. LATER TONIGHT...WITH AXIS OF SURFACE RIDGE RUNNING FROM CENTRAL KANSAS...THROUGH SOUTHEAST NEBRASKA AND INTO WEST CENTRAL IOWA...MAY SEE SOME PATCHY FOG DEVELOPING WITH THE CLEARING SKIES IN NORTHWEST MISSOURI AND NORTHEAST KANSAS. FOR MONDAY...UPPER LOW MOVES EAST OF REGION...BUT WITH COLD POOL STILL AFFECTING AREA...WILL SEE LAPSE RATES SUPPORT SOME CU FIELD DEVELOPING AGAIN. SOUNDINGS WOULD SUGGEST TEMPERATURES LEVELING OFF IN THE MIDDLE TO UPPER 70S AFTER THESE CLOUDS DEVELOP...SO ANOTHER UNSEASONABLY COOL DAY EXPECTED. SURFACE RIDGE SETS UP OVER CENTRAL MISSOURI MONDAY NIGHT...SO WITH CLEAR SKIES AND LIGHT WINDS...SHOULD SEE SOME MORE VERY COOL NIGHTTIME LOWS...ESPECIALLY IN EASTERN HALF OF FORECAST AREA. THEN WARM UP BEGINS ON TUESDAY AS RETURN FLOW SETS UP BY AFTERNOON. STILL WEAK EVEN AT THAT POINT...SO SHOULD STILL HAVE TEMPERATURES AT LEAST 5 DEGREES COOLER THAN NORMAL AFTER THE CHILLY START TO THE DAY. THE MEDIUM RANGE MODELS ARE IN DECENT AGREEMENT WITH THE LARGE SCALE WEATHER FEATURES FOR THE SECOND HALF OF THE WEEK. THE POTENT UPPER SHORTWAVE MOVING INTO BRITISH COLUMBIA THIS AFTERNOON IS FORECAST TO DEEPEN AS IT MOVES SLOWLY INTO THE CANADIAN HIGH PLAINS. FOR KANSAS AND MISSOURI, THE UPPER LOW OVER SOUTHERN CANADA MEANS LOW HEIGHTS AND RELATIVELY STRONG MID LEVEL ZONAL FLOW. LEE SIDE TROUGHING WILL ACT TO DISPLACE COOL SURFACE HIGH PRESSURE OVER THE REGION ON WEDNESDAY, AND LOW LEVEL MOISTURE WILL BEGIN TO RETURN TO THE REGION. I BELIEVE THAT THE 00Z GFS MAY BE A BIT PREMATURE WITH ITS CONVECTION OVER KANSAS DURING THE DAY WEDNESDAY, BUT AS THE CENTRAL HIGH PLAINS HEATS UP WEDNESDAY AFTERNOON, A CONVECTIVE COMPLEX SHOULD FORM LATE WEDNESDAY SOMEWHERE IN THE WESTERN HIGH PLAINS. WITH RELATIVELY STRONG FLOW, THIS COMPLEX HAS A GOOD CHANCE TO MAKE IT INTO EASTERN KANSAS AND WESTERN MISSOURI LATE WEDNESDAY NIGHT INTO THURSDAY. SO, IN THE EXTENDED FORECAST MY BEST CHANCES FOR PRECIPITATION ARE WEDNESDAY NIGHT INTO THURSDAY. THE GFS BECOMES CLUTTERED WITH CONVECTIVE FEEDBACK FROM ASSORTED MESOSCALE COMPLEXES BY LATE IN THE WEEK, SO FORECAST CONFIDENCE DECREASES SIGNIFICANTLY FRIDAY THROUGH SUNDAY. IVE MAINTAINED SOME 30 PERCENT CHANCES FRIDAY WITH RELATIVELY COOL MID LEVEL TEMPERATURES AND ABUNDANT LOW LEVEL MOISTURE EXPECTED. FOR SATURDAY AND SUNDAY, IVE KEPT THE FORECAST DRY FOR NOW. THE GFS ADVERTISES A TRANSITION TO NORTHWEST FLOW SO THIS TREND WILL HAVE TO BE MONITORED. AT THIS TIME, THE GFS SUGGESTS LITTLE CAPPING NEXT WEEKEND, SO CLUSTERS OF STORMS COULD TRACK INTO THE REGION FROM NEBRASKA AND THE DAKOTAS. OTHERWISE, A RETURN TO AVERAGE TEMPERATURES AND MORE HUMID CONDITIONS LOOKS INEVITABLE FOR THE END OF THE WEEK. KOCH && .PREV DISCUSSION... 404 AM... WATERVAPOR LOOP SHOWS WEAK SHORTWAVE MOVING ACROSS SOUTHEAST MISSOURI AS MID LEVEL TROUGH PUSHES INTO THE CENTRAL PLAINS. MID LEVEL TROUGH PROGGED TO MOVE ACROSS THIS AFTERNOON AND TONIGHT...DEVELOPING A CUT OFF LOW EAST OF THE FORECAST AREA. TROUGH SHOULD PROVIDE ENOUGH LIFT FOR ABUNDANT CLOUDS ACROSS THE ENTIRE AREA. DESPITE A STRENGTHENING LOW OVER THE REGION HOWEVER...HAVE MAINTAINED POPS AT LESS THAN 15 PERCENT. SUBSIDENCE BEHIND LEADING SHORTWAVE...COUPLED WITH LEFT REAR QUAD OF UPPER LEVEL JET SHOULD LIMIT PRECIP TO NO MORE THAN SPRINKLES...IF ANY. HAVE ALSO MAINTAINED THE SLOW WARMUP EARLY THIS WEEK. 850MB TEMPS REMAIN COOL THROUGH THE NEXT SEVERAL DAYS...AS THERMAL TROUGH LINGERS THROUGH TUESDAY. RECORD LOWS FOR TOMORROW MORNING SHOULD HOLD...BUT WILL BE CLOSE. RECORD LOW FOR MCI IS 55(1962)...STJ IS 51(1971). ETA IS QUICKER AND STRONGER THAN THE GFS IN BRINGING RIDGE BACK INTO THE REGION BY LATE TUESDAY. HOWEVER WILL NOT JUMP ON THE QUICK WARMUP AS SURFACE WINDS REMAIN FROM THE SOUTHEAST AND WINDS UP THROUGH 850MB LOOK TO REMAIN ON THE WEAK SIDE. GFS BRINGS MORE MOISTURE INTO THE REGION WEDNESDAY/WEDNESDAY NIGHT. ETA IS TYPICALLY TOO DRY. SO HAVE INCREASED POPS TO 30 FOR WARM AIR ADVECTION PRECIP WEDNESDAY NIGHT INTO THURSDAY ACROSS THE FORECAST AREA. NRR 830 PM SAT... 00Z UPPER AIR ANALYSIS AND WATER VAPOR IMAGERY INDICATE SHORTWAVE TROUGH AXIS CURRENTLY LOCATED OVER MID MS VALLEY...AND REGIONAL RADAR IMAGERY SHOWS ASSOCIATED PRECIPITATION HAS SHIFTED OUT OF FORECAST AREA. SUBSIDENCE BEHIND THIS FEATURE HAS ALLOWED LOW CLOUDS TO DISSIPATE ACROSS NORTHEAST KS AND NORTHWEST MO. DESPITE ABUNDANT RESIDUAL SURFACE MOISTURE FROM TODAYS RAINFALL...THINK SUFFICIENT MID LEVEL CLOUD COVER SHOULD KEEP DENSE FOG FROM DEVELOPING...HOWEVER MID SHIFT WILL NEED TO KEEP CLOSE EYE ON THIS. OTHERWISE GOING TEMPS FOR TONIGHT LOOK REASONABLE...AND SHOULD CHALLENGE RECORD LOW AT MCI (56) SUNDAY MORNING. SECONDARY SHORTWAVE TROUGH CURRENTLY DIGGING INTO CENTRAL HIGH PLAINS IS EXPECTED TO DEEPEN AS IT PROPAGATES ACROSS THE CENTRAL PLAINS INTO THE LOWER MO VALLEY TONIGHT INTO THE DAY SUNDAY. 850MB BAROCLINIC ZONE HAS BEEN PUSHED SOUTH OF AREA...AND IS CURRENTLY LOCATED FROM SOUTHERN MO INTO CENTRAL OK. EXPECT ANY THETA-E ADVECTION WITHIN 925-850MB LAYER TO REMAIN SOUTH OF FORECAST AREA...ALTHOUGH CANT RULE OUT SHOWERS LATE TONIGHT ACROSS FAR SOUTHEAST. HAVE UPDATED FORECAST TO REMOVE POPS ACROSS ALL BUT FAR SOUTHEAST FOR THE OVERNIGHT HOURS. SEAMAN && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. WFO EAX
