AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 253 PM CDT SAT AUG 28 2004 .DISCUSSION... MORE INSTABILITY HAS DEVELOPED THIS AFTERNOON IN THE MUCK AHEAD COLD FRONT THAN PREVIOUSLY THOUGHT, AND CLUSTERS OF SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON FROM SEDALIA UP TO KIRKSVILLE. THE LINE OF SHOWERS (AND THE COLD FRONT) ARE MOVING TO THE EAST AT 20 MPH AND WILL PASS THROUGH MACON AND BOONVILLE BY 5 PM. ONCE THE FRONT PUSHES THROUGH THE FORECAST AREA, AN EXTENDED PERIOD OF QUIET AND MUCH DRIER WEATHER IS EXPECTED. WARM ADVECTION WILL NEED TO BE MONITORED OVER NORTHEAST KANSAS AND NORTHWEST MISSOURI EARLY MONDAY MORNING AS 850MB MOISTURE INCREASES. BUT AT THIS TIME 700-500MB LAPSE RATES FROM THE ETA DO NOT APPEAR TO BE CONDUCIVE TO ELEVATED THUNDERSTORM DEVELOPMENT. A NARROW AXIS OF HIGH PRESSURE WILL BUILD INTO IOWA, NORTHERN MISSOURI, AND EASTERN KANSAS TONIGHT. LOW LEVEL STRATOCUMULUS OVER EASTERN NEBRASKA SHOULD DISSIPATE THIS EVENING WITH THE LOSS OF SURFACE HEATING AND THE CENTRAL PLAINS SHOULD CLEAR OUT. FOG DEVELOPMENT IS A CONCERN LATE TONIGHT INTO TOMORROW MORNING, BUT THERE ARE A COUPLE OF FACTORS WORKING AGAINST WIDESPREAD FOG DEVELOPMENT. WIND GRADIENTS WILL BE TIGHT ENOUGH THIS EVENING TO KEEP THE REGION RELATIVELY WELL MIXED. DRY AIR ADVECTION WILL ALSO BE A FACTOR THIS EVENING. BY LATE TONIGHT, SURFACE WINDS WILL DECOUPLE ESPECIALLY IN SHELTERED AREAS, BUT FORECAST SOUNDINGS SHOW WINDS BETWEEN 5 AND 10 KNOTS OVER A RELATIVELY SHALLOW INVERSION LAYER. THIS WILL LEAD TO MIXING JUST ABOVE THE GROUND AND WILL RETARD FOG FORMATION. SO DESPITE ABUNDANT SURFACE MOISTURE, CLEAR SKIES, AND RELATIVELY LIGHT WINDS, I AM NOT EXPECTING MUCH DENSE FOG. FOR NOW I WILL CARRY PATCHY/AREAS OF FOG WITH NO DENSE FOG WORDING, AND THE EVENING SHIFT CAN MONITOR WIND PROFILERS TO GAGE THE DEPTH OF THE INVERSION LAYER. THE REST OF THE FORECAST LOOKS QUIET. NGM MOS HAS PERFORMED BETTER THAN THE GFS AND ETA WITH TEMPERATURES THIS SUMMER IN GENERAL. IT IS A BIT COOLER AND SHOULD VERIFY BETTER THIS CYCLE SINCE THE GROUND IS SO WET. KOCH .PREV DISCUSSION... 1129 AM... THE COLD FRONT THAT INITIATED STORMS LAST EVENING HAS MOVED VERY LITTLE DURING THE LAST 12 HOURS, AND NOW APPEARS TO BE STRETCHING FROM NEAR KIRKSVILLE TO HARRISONVILLE. OUTFLOW BOUNDARIES FROM INTENSE CONVECTION OVERNIGHT WILL FOCUS STORMS WELL SOUTH AND EAST OF THE PLEASANT HILL FORECAST AREA TODAY. WITH RAIN SHOWERS ENDING OVER CENTRAL MISSOURI, I HAVE UPDATED THE FORECAST TO DECREASE PRECIPITATION CHANCES AND THE MAJORITY OF THE RAIN SHOULD BE EAST OF KIRKSVILLE SHORTLY AFTER NOON. THE EXTENDED FORECAST HAS ALSO BEEN UPDATED, AND NO CHANGES ARE ANTICIPATED THIS AFTERNOON FOR DAYS 4 THROUGH 7. THE MEDIUM RANGE MODELS ARE IN VERY GOOD AGREEMENT ADVERTISING A FLAT RIDGE ANCHORED OVER THE WESTERN HALF OF THE COUNTRY. HIGH PRESSURE WILL RESIDE OVER THE MIDWEST FOR MUCH OF THE WEEK. LOW LEVEL MOISTURE WILL BE SLOW TO RETURN TO THE REGION IN THIS WEAK SURFACE FLOW REGIME. TEMPERATURES NEAR AVERAGE ARE EXPECTED AND PRECIPITATION CHANCES ARE LOW THROUGH THE WEEKEND. KOCH && 317 AM... THE HEAVY RAINFALL EVENT APPEARS TO BE BEGINNING TO COME TO AN END ACROSS THE FORECAST AREA EARLY THIS MORNING...AS AREAL COVERAGE AND INTENSITY OF CONVECTION ON RADAR IMAGERY CONTINUES TO DECREASE. THIS TREND IS SUPPORTED BY LATEST IR SATELLITE IMAGERY...WHICH PORTRAYS SIGNIFICANT CLOUD TOP WARMING. CURRENT ANALYSIS OF SURFACE OBSERVATIONS INDICATES THAT THE FRONT IS STILL LOCATED ROUGHLY ALONG A SOUTH KANSAS CITY TO KIRKSVILLE LINE. DUE TO THE POTENTIAL FOR ADDITIONAL TRAINING OF CELLS TO EASILY EXACERBATE CURRENT FLOODING PROBLEMS...WILL HOLD ONTO THE FLOOD WATCH UNTIL ITS 6 AM EXPIRATION. WILL TAPER POPS TO BELOW 20 PERCENT BY THIS AFTERNOON...AS EXPECT THE FRONT WILL HAVE ENTIRELY EXITED THE CWA BY 18Z. THIS WILL BE THE FINALE TO A WEEKS WORTH OF ACTIVE WEATHER...AS SURFACE HIGH PRESSURE BUILDS IN LATE SATURDAY AND SUNDAY. THE PRESENCE OF THE LOW-LEVEL RIDGE AND SATURATED GROUND CONDITIONS WILL LIKELY SET THE STAGE FOR FOG FORMATION OVERNIGHT SATURDAY INTO SUNDAY...SO HAVE TWEAKED GRIDS/ZONES ACCORDINGLY. AS FAR AS TEMPERATURES ARE CONCERNED...LEANED TOWARD THE LOWER END OF GUIDANCE TODAY DUE TO SATURATED GROUND CONDITIONS AND NORTHERLY LOW LEVEL FLOW. TEMPERATURES WILL MODERATE TO NEAR NORMAL READINGS EARLY IN THE UPCOMING WORK WEEK AS WEAK RIDGING BUILDS OVER THE SOUTHWEST CONUS. SCHMIT && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE.
