NWS Kansas City, MO wrote its last area forecast discussion before the first event at Aug 29, 1:58 AM CST, 6 hours 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 258 AM CDT SUN AUG 29 2004 .DISCUSSION... FORECAST CONCERN ON THE FOREFRONT IS POTENTIAL FOG DEVELOPMENT THIS MORNING. SKIES HAVE BECOME CLEAR FOR THE MOST PART...EXCEPT FOR THE EDGE OF A LOW CLOUD DECK INCHING INTO THE EASTERN FRINGE OF THE CWA. THE CLEAR SKIES ALONG WITH LIGHT SURFACE WINDS GENERALLY LESS THAN 5 KNOTS WILL PROVIDE THE SETUP FOR FOG DEVELOPMENT THIS MORNING. AM EXPECTING PATCHY DENSE FOG IN FAVORABLE LOCATIONS SUCH AS LOW LYING AREAS AND RIVER VALLEYS...HOWEVER WIND PROFILES OF 10 KNOTS ABOVE THE SURFACE AND WITHIN THE INVERSION LAYER DO NOT SUGGEST WIDESPREAD DENSE FOG WILL DEVELOP. THE FOG THAT DOES DEVELOP IS EXPECTED TO LAST A FEW HOURS AND BURN OFF BY MID MORNING. LOOKING AT THE FOG POTENTIAL FOR EARLY MONDAY MORNING...FORECAST WIND PROFILES INDICATE SOUTHERLY WINDS FROM 10 TO 20 KNOTS WITHIN THE INVERSION LAYER ACROSS THE WESTERN FORECAST AREA...WITH LIGHTER/MORE FAVORABLE WINDS ACROSS EASTERN SECTIONS. WILL NOT MENTION FOG AT THIS POINT FOR MONDAY MORNING WITH FORECAST SOUNDINGS KEEPING THE DEPTH OF MOISTURE EXTREMELY SHALLOW. WITH SURFACE HIGH PRESSURE SLIDING INTO PLACE ACROSS THE FORECAST AREA...TEMPERATURES TODAY SHOULD WARM INTO THE MID 70S TOWARD NORTHEAST MISSOURI...AND NEAR TO JUST ABOVE 80 DEGREES ACROSS WESTERN MISSOURI AND EXTREME EASTERN KANSAS. A WEAK SURFACE FRONT IS FORECAST TO WASH OUT AS IT APPROACHES THE NORTHWEST CORNER OF MISSOURI EARLY MONDAY MORNING. WITH BETTER FORCING HELD TO THE NORTH...ANY HIGH BASED SHOWERS WOULD NEED TO PENETRATE THE LOW LEVEL DRY LAYER...SO HAVE KEPT A DRY FORECAST GOING AT THIS JUNCTURE. A GRADUAL WARMING TREND WILL CONTINUE INTO THE WORK WEEK AS SURFACE HIGH PRESSURE IS REINFORCED WITH A FLATTENED UPPER RIDGE BECOMING THE DOMINANT FEATURE ACROSS THE WESTERN 2/3RDS OF THE CONUS. STOFLET && .PREV DISCUSSION... 1015 PM SAT... A FEW CONCERNS ABOUT DENSE FOG TONIGHT. SOME THINGS AGAINST IT ARE THE BKN-OVC CLOUDS STILL IN NORTHWEST MO...AND THE WINDS ARE STILL 5-7KTS. WILL SEE A RIDGE OVERHEAD TONIGHT...SO THE SURFACE WINDS SHOULD DECOUPLE. ALTHOUGH AT 2Z, LATHROP PROFILER HAD 20KT WINDS AT H8...WHICH ISNT CONDUCIVE FOR DENSE FOG. FOGPLOT PUTS DENSE FOG IN 2 OF THE THREE TAF SITES. PRETTY SURE WE WILL SEE DENSE FOG AROUND ESPECIALLY IN LOW LYING AREAS AND RIVER VALLEYS...BUT ENOUGH UNCERTAINTY TO PRECLUDE ISSUING A DENSE FOG ADVISORY RIGHT NOW. HAVE UPDATED GRIDS TO MENTION AREAS OF DENSE FOG FOR NOW. ZFP ALREADY OUT. LVQ 253 PM SAT... 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 1129 AM SAT... 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.
