AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 334 AM CDT MON MAY 31 2004 .DISCUSSION... MAIN FORECAST CONCERN IS WITH CHANCES OF PRECIPITATION THE NEXT FEW DAYS. FINALLY A BREAK FROM THE BIG WEATHER...BUT WILL BE DEALING WITH PESKY CHANCE OF PRECIPITATION AS UPPER LOW OVER UPPER MIDWEST THIS MORNING WILL BE SLOW TO MOVE OUT. SOME DISCREPANCIES IN THE MODELS WITH HANDLING OF THIS...WITH GFS HOLDING ONTO CUT OFF LOW OVER IOWA THROUGH WEDNESDAY WHILE ETA KEEPS TROUGHING OVER AREA...BUT NOT AN ACTUAL CUT OFF. WILL AIM AT A BIT OF A COMPROMISE SOLUTION WITH KEEPING WEST TO EAST ORIENTED TROUGH OVER AREAS JUST TO THE NORTH ON WEDNESDAY MORNING. THIS TROUGH IS EXPECTED TO SWING THROUGH MISSOURI DURING THE DAY ON WEDNESDAY. FOR TODAY...LOOKING AT STEEPENING LAPSE RATES OCCURRING ACROSS FORECAST AREA BY AFTERNOON...WITH ONLY WEAK CAPPING. MOISTURE WILL BE LIMITING FACTOR...BUT SOME MOISTURE SHOWING UP IN THE 800 TO 700 LEVEL THAT SHOULD BE ENOUGH TO GET AT LEAST SOME ISOLATED SHOWERS AND THUNDERSTORMS GOING. WEAK WAVE ALSO SHOWING UP AT 700 MB WRAPPING AROUND UPPER LOW AND ETA SHOWING DECENT LIFT INTO WESTERN PORTIONS OF FORECAST AREA BY 00Z. WILL NOT GET TOO CUTE WITH TRYING TO GUESS EXACTLY WHERE ANY CONVECTION MIGHT ERUPT...SINCE THERE IS NOT A GOOD BOUNDARY TO KEY ON...AND DO NOT WANT ANYONE TO GET SURPRISED BY A THUNDERSTORM THIS AFTERNOON OR EVENING WHILE THEY ENJOY THE MEMORIAL HOLIDAY...SO WILL INTRODUCE LOW POPS FOR ENTIRE FORECAST AREA...THEN END THEM IN SOUTHEAST AREAS...WHERE BETTER LIFT IS SHOWING UP THIS EVENING AS 700 WAVE MOVES PAST. FOR TUESDAY...WITH UPPER LOW STILL TO OUR NORTH...AND ADDITIONAL WAVES MOVING AROUND ITS SOUTHERN PERIMETER...WILL KEEP SOME POPS MENTIONED IN NORTHERN AREAS WHERE SOME LIFT IS SHOWING UP AT MID LEVEL. FOR WEDNESDAY WILL LIMIT POPS JUST TO THE NORTHEAST AREAS...AS THINK THAT WILL BE THE AREA OF BEST LIFT WITH UPPER WAVE DROPPING SOUTHEAST ACROSS MID MISSISSIPPI VALLEY. HOWEVER...WITH MODELS NOT IN GREAT AGREEMENT THAT DAY...COULD SEE THIS FORECAST GETTING SOME ADJUSTMENTS OVER THE NEXT FEW MODEL RUNS. HEAT WILL BE KEPT AT BAY WITH UPPER LOW JUST TO OUR NORTH...ALTHOUGH WESTERLY COMPONENT TO THE WIND TODAY AND TUESDAY ALONG WITH ENOUGH SUNSHINE SOUTHWEST HALF OF FORECAST AREA...THAT LOWER 80S SEEM QUITE REASONABLE. EXPECTING MORE CLOUDINESS ON WEDNESDAY WITH UPPER TROUGH MOVING THROUGH REGION...AND WINDS TAKING ON A MORE NORTHERLY DIRECTION...THAT AFTERNOON HIGHS SHOULD BE SEVERAL DEGREES COOLER WITH LOWS THURSDAY MORNING THE COOLEST OF THE WEEK BEFORE RETURN FLOW STARTS TO SET UP. PC && .PREVIOUS DISCUSSION... 600 PM... SEVERE STORMS HAVE CLEARED OUR COUNTIES, AND I HAVE FINALLY HAD A CHANCE TO LOOK AT THE FORECAST IN MORE DETAIL. THE UPPER TROUGH AXIS IS SWINGING THROUGH KANSAS THIS EVENING AND HAS AIDED IN THE INITIATION OF SOME THUNDERSTORMS ALONG THE NEBRASKA KANSAS BORDER BETWEEN MARYSVILLE AND HIAWATHA. THESE STORMS ARE DIURNALLY DRIVEN WITH LESS THAN 1000 J/KG OF CAPE. AS THE SUN SETS, THE STORMS WILL LIKELY DIMINISH OVER NORTHWEST MISSOURI AROUND MARYVILLE. THE BIGGEST CHANGE TO THE FORECAST WAS THE ADDITION OF SOME AFTERNOON SHOWERS AND THUNDERSTORMS FOR NORTH CENTRAL AND NORTHEASTERN MISSOURI TOMORROW AND TUESDAY. THE UPPER LEVEL LOW CENTERED OVER MINNESOTA IS EXPECTED TO MOVE LITTLE DURING THE NEXT TWO DAYS. AS THE UPPER LOW DRIFTS SOUTH NORTHERN MISSOURI WILL DEVELOP STEEP LAPSE RATES IN THE AFTERNOON FROM THE SURFACE TO 700MB. LOW LEVEL MOISTURE WILL BE LIMITED, BUT SUBSTANTIAL ENOUGH TO YIELD SURFACE BASED CAPES BETWEEN 500 AND 1000 J/KG. WITHOUT A SURFACE FEATURE TO INITIATE AFTERNOON CONVECTION, CONVECTION WILL BE ISOLATED TO SCATTERED. ANY STORMS THAT DO FORM WILL HAVE THE POTENTIAL TO PRODUCE LARGE HAIL SINCE FREEZING LEVELS WILL BE LESS THAN 9000 FEET. KOCH 300 PM... WITH ONGOING CONVECTION AND LINGERING FLOODING PROBLEMS IN A HANDFUL OF NORTHERN MISSOURI COUNTIES, I HAVE HAD VERY LITTLE TIME TO ANALYZE THE MODELS FOR A NEW FORECAST. THE LINE OF STORMS FROM KIRKSVILLE TO SEDALIA CONTINUES TO MOVE EAST AROUND 30 MPH AND SHOULD BE OUT OF THE FORECAST AREA BETWEEN 4 PM AND 5 PM. ONCE THE STORMS CLEAR OUR FORECAST AREA, I WILL CANCEL THE TORNADO WATCH FOR THE REMAINDER OF THE PLEASANT HILL FORECAST AREA. THEN EARLY THIS EVENING I WILL PUBLISH NEW GRIDS AND A NEW FORECAST THROUGH THE SEVEN DAY PERIOD. A PRELIMINARY LOOK AT THE MODELS SUGGESTS THAT THERE IS AT LEAST THE POTENTIAL FOR SOME ISOLATED TO SCATTERED THUNDERSTORMS TOMORROW AFTERNOON OVER NORTHERN MISSOURI IN THE NORTHWEST FLOW WITH COLD TEMPERATURES ALOFT. INSTABILITY IS PROGGED BY THE ETA TO BE AROUND 500-1000 J/KG WITH SOME SPEED SHEAR IN THE NORTHWEST FLOW. THE STORMS PREDICTION CENTER HAS ALL OF NORTHERN MISSOURI OUTLOOKED FOR A SLIGHT RISK OF SEVERE THUNDERSTORMS SO I WILL LIKELY ADD SOME CHANCE FOR AFTERNOON THUNDERSTORMS FOR MISSOURI COUNTIES. ANOTHER AREA FORECAST DISCUSSION WILL BE ISSUED EARLY THIS EVENING WITH THE UPDATED FORECAST. KOCH 915 AM... MORNING SURFACE ANALYSIS INDICATES COLD FRONT REMAINS WEST OF FORECAST AREA ACROSS EXTREME EASTERN NE INTO EASTERN KS. ADDITIONALLY...OUTFLOW BOUNDARY FROM OVERNIGHT CONVECTION ANALYZED JUST SOUTH OF I-70 CORRIDOR...INTERSECTING COLD FRONT JUST W OF KC METRO AREA. LOW 70 DEW POINTS NOTED ALONG/SOUTH OF THIS BOUNDARY...WHILE LOW/MID 60 DEW POINTS AND BACKED WINDS NOTED ON COOL SIDE OF BOUNDARY. WATER VAPOR IMAGERY INDICATES SHORTWAVE TROUGH/VORT MAX LOCATED ACROSS CENTRAL KS INTO TX PANHANDLE. THIS FEATURE IS EXPECTED TO EJECT EASTWARD INTO LOWER MO VALLEY THROUGH THIS AFTERNOON. AM BECOMING INCREASINGLY CONCERNED CONVECTIVE INITIATION MAY OCCUR EARLY THIS AFTERNOON AT INTERSECTION OF OUTFLOW BOUNDARY/SURFACE FRONT JUST EAST OF KC METRO AREA ALONG I-70 CORRIDOR. ANY STORMS WHICH ARE ABLE TO DEVELOP IN THIS ENVIRONMENT AND INTERACT WITH OUTFLOW BOUNDARY WILL RAPIDLY BECOME SEVERE/SUPERCELLULAR GIVEN DEGREE OF SHEAR/INSTABILITY...WITH ATTENDANT THREAT FOR TORNADOES IN ADDITION TO HAIL/WINDS. WILL UPDATE HWO TO HIGHLIGHT THIS THREAT...OTHERWISE EXPECT SEVERE THREAT TO SHIFT EAST OF FORECAST AREA BY MID TO LATE AFTERNOON AS WESTERLY LOW LEVEL FLOW SHUNTS DEEP MOISTURE EAST OF CWA.

AT THIS TIME...NO SEVERE WEATHER IS ANTICIPATED WITH THIS ACTIVITY.
