AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 250 AM CDT TUE APR 12 2005 .DISCUSSION... EARLY MORNING WATER VAPOR IMAGERY AND OBJECTIVE UPPER AIR ANALYSIS DEPICT HIGHLY AMPLIFIED BLOCKING PATTERN ACROSS CONUS THIS MORNING. UPPER LOWS LOCATED OFF NORTHEAST/PACIFIC NORTHWEST COAST WITH BROAD NORTHERN STREAM UPPER RIDGE STRETCHING ACROSS MUCH OF CENTRAL CANADA. EMBEDDED BENEATH THIS RIDGE...UPPER LOW CENTERED OVER SOUTHEASTERN KS CONTINUES TO DRIFT VERY SLOWLY SOUTHEASTWARD. SURFACE ANALYSIS INDICATED FAIRLY BROAD AREA OF LOW PRESSURE ACROSS NORTHERN MO WITH SURFACE COLD FRONT STRETCHING BACK ACROSS SOUTHERN KS/WESTERN OK. NARROW AXIS OF MOISTURE IN PLACE AHEAD OF THIS FRONT ACROSS EASTERN MO INTO IA. WEAK FLOW COMBINED WITH MOISTURE CONVERGENCE ALONG THIS BOUNDARY APPEARS TO BE RESPONSIBLE FOR PATCHY DENSE FOG WHICH HAS DEVELOPED AROUND THE KMCI AREA. EXPECT THIS TO REMAIN SHORT LIVED AND LOCALIZED ALONG BOUNDARY IVOF WEAK SURFACE LOW. PRIMARY CONCERNS FOR TODAY ARE PRECIPITATION CHANCES...EXTENT OF CLOUD COVER AND ITS EFFECT ON MAX TEMPERATURES. GIVEN PROXIMITY OF UPPER LOW...NARROW AXIS OF LOW LEVEL MOISTURE AND WEAK FORCING ALONG SURFACE BOUNDARY...HAVE MAINTAINED POPS ACROSS ENTIRE CWA TODAY...WITH HIGHEST POPS (60S) ACROSS NORTHEAST WHERE BETTER MOISTURE RESIDES. MAY REFINE MORNING PRECIP FORECAST BASED ON RADAR TRENDS BEFORE MAKING GRIDS OFFICIAL. OTHERWISE BAND OF MVFR CEILINGS IN PLACE ALONG/BEHIND AFOREMENTIONED SURFACE BOUNDARY...WITH LARGER AREA OF STRATUS UPSTREAM ACROSS DAKOTAS/NORTHERN NE...WHILE DRY SLOT HAS WORKED INTO SOUTHEAST KS/SOUTHWEST MO AHEAD OF COLD FRONT. EXPECT AREAS BEHIND SURFACE FRONT TO REMAIN OVERCAST THROUGHOUT MOST OF THE DAY TODAY. MAX TEMPS BEHIND FRONT WILL BE TRICKY...AS TEMPS ACROSS EASTERN NE HAVE ALREADY FALLEN INTO THE 30S TO LOWER 40S...HOWEVER TEMPS IMMEDIATELY BEHIND FRONT REMAIN IN THE LOW 50S ACROSS NORTHWEST MO. FOR NOW HAVE GONE A CATEGORY OR SO BELOW GUIDANCE WITH MAX TEMPS IN THE MID 50S GIVEN VERY SLOW MOVEMENT OF FRONTAL BOUNDARY. UPPER LOW PROGGED TO SLOWLY TRANSLATE SOUTHEAST AWAY FROM REGION TONIGHT AS RIDGING BUILDS ACROSS NORTHERN PLAINS. HAVE MAINTAINED LOW CHANCE POPS FOR OVERNIGHT HOURS...AND REMOVED POPS FOR WEDNESDAY AS DRIER LOW/MID LEVEL AIR ADVECTS SOUTHWARD. MID LEVEL RIDGE PROGGED TO REMAIN ACROSS CENTRAL PLAINS THROUGH THURSDAY NIGHT...BEFORE SHIFTING EAST FRIDAY AS SHORTWAVE TROUGH TRANSLATES ACROSS NORTHERN ROCKIES INTO NORTHERN PLAINS FRIDAY NIGHT. ASSOCIATED SURFACE FRONT LOOKS TO REACH FORECAST AREA SATURDAY...RESULTING IN A CHANCE OF SHOWERS AND THUNDERSTORMS. AT THIS TIME FLOW ALOFT APPEARS WEAK ACROSS REGION...THUS AM NOT ANTICIPATING SEVERE WEATHER THREAT. SEAMAN && .PREV DISCUSSION... 925 PM MON... HAVE UPDATED FORECAST FOR TONIGHT AND TUESDAY. FOR TONIGHT HAVE BASICALLY DROPPED MENTION OF RAIN OVER SOUTHWEST PORTION OF CWA...LEFT IN A TOKEN SLIGHT CHANCE TOWARDS TOMORROW MORNING FOR APPROACH OF WRAP AROUND SHOWERS BUT CONFIDENCE LOW. OTHERWISE...BEST BET FOR RAIN TONIGHT IS OVER NORTHERN AND EASTERN CWA TAPERING TO CHANCE WORDING OVER WEST CENTRAL MO. QUITE COLD OVER WESTERN AND CENTRAL KS THIS AFTERNOON ON BACK SIDE OF CLOSED SYSTEM. THIS AIRMASS WILL BE ADVECTED EAST INTO EASTERN KS AND WESTERN MO TOMORROW. THINK CURRENT MAX TEMPERATURES ARE TOO WARM AND HAVE LOWERED BY A CATEGORY TO MID 50S...AND THAT MAY STILL BE TOO WARM. MJ && .PREV DISCUSSION... 407 PM... IN THE NEAR TERM...SURFACE LOW HAS REMAINED NEARLY STATIONARY ALL DAY WITH CENTER BTWN MHK AND CNK AT 21 UTC. MODERATE CONVECTION CONTINUES TO BUBBLE ALONG THE INSTABILITY AXIS BELOW COLD POOL ALOFT...AND EXPECT THIS TREND TO CONTINUE THROUGH 00 UTC. LOSS OF DIURNAL HEATING MAY MEAN THE DEATH KNELL FOR SEVERE CONVECTION FOR EAX CWFA...BUT WITH INTERACTION OF COLD POOL AND MODEST SPEED/DIRECTIONAL SHEAR PLUS DECENT MOISTURE POOLING...CANNOT RULE OUT POSSIBILITY OF NON-SEVERE CONVECTION OVERNIGHT. BEST LIKELIHOOD FOR PRECIP WILL BE INVOF LOW/UPR LOW COUPLET THAT WILL TRACK FROM NORTHEAST KANSAS INTO NORTH CENTRAL MISSOURI OVERNIGHT...WITH CHANCE PRECIP GENERALLY ALONG AND SOUTH OF HIGHWAY 50. LOW LEVEL CAA LATE TONIGHT COUPLED WITH EVAPORATIVE COOLING WILL RESULT IN MINIMUM TEMPERATURES 5-10 DEGREES COOLER THAN THOSE SEEN MONDAY MORNING. PREVIOUS FORECAST MINIMUM TEMPERATURES LOOKED REASONABLE...SO ONLY TWEAKED. SF THE CENTER OF THE UPPER LOW WILL CONTINUE ITS MOVEMENT TO THE EAST ACROSS SOUTHERN MISSOURI DURING THE DAY TOMORROW...BEFORE TURNING A BIT TO THE SOUTHEAST TOMORROW NIGHT. THE SURFACE LOW WILL ALSO CONTINUE ITS EASTWARD TRACK BEFORE HEADING SOUTHEAST TOMORROW NIGHT. THE FORECAST AREA WILL BE ON THE BACKSIDE OF THESE FEATURES TOMORROW...WITH THE CONTINUING POSSIBILITY OF SHOWERS. HAVE INSERTED MENTION FOR A FEW THUNDERSTORMS CONFINED TO EASTERN PORTIONS OF THE FORECAST AREA TOMORROW AFTERNOON. HAVE LOWERED TEMPERATURES INTO THE UPPER 50S TO NEAR 60 DEGREES TOMORROW AS NEUTRAL TEMPERATURE ADVECTION AND CLOUD COVER SHOULD HINDER WARMING. LOW END PRECIPITATION CHANCES THEN LINGER INTO WEDNESDAY BEFORE SHUTTING OFF AS THE LOW PRESSURE SYSTEM PULLS FURTHER AWAY TO THE SOUTHEAST. A BACK DOOR COLD FRONT IS FORECAST TO TRAVERSE THE AREA WEDNESDAY...WHICH SHOULD BRING ADDITIONAL CLOUD COVER AND KEEP MAX TEMPERATURES SIMILAR TO THOSE TOMORROW. MID/UPPER LEVEL RIDGING WILL THEN BECOME THE DOMINANT FEATURE ACROSS THIS AREA THROUGH FRIDAY...BRINGING REDUCED CLOUD COVER AND A MODERATION OF TEMPERATURES. AN UPPER LEVEL SHORTWAVE THEN ADVANCES ACROSS THE NORTHERN CONUS AND DRAGS AN ATTENDANT SURFACE FRONT INTO THE AREA ON SATURDAY. THE MAIN UPPER LEVEL ENERGY LOOKS TO BE KEPT NORTH OF THE FORECAST AREA...BUT HAVE CONTINUED WITH THE CHANCE FOR SHOWERS AND THUNDERSTORMS IN THE VICINITY OF THE SURFACE FRONT ON SATURDAY.
