AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 315 PM CDT FRI JUL 16 2004 .DISCUSSION... MEAN NORTHWEST FLOW ALOFT REMAINS ACROSS THE REGION...AS HIGH AMPLITUDE MID LEVEL RIDGE REMAINS IN PLACE ACROSS THE ROCKIES/INTERMOUNTAIN WEST. CONVECTIVELY INDUCED VORTICITY FEATURES ARE EVIDENT EARLY THIS AFTERNOON OVER SOUTHEAST MO AND SOUTH CENTRAL KS...WHILE FURTHER NORTH WEAK SHORTWAVE TROUGH IS NOTED DIGGING THROUGH WESTERN GREAT LAKES REGION. SURFACE FRONT ASSOCIATED WITH THIS FEATURE APPEARS TO STRETCH FROM CENTRAL WI ACROSS EASTERN IA AND INTO WEST CENTRAL MO...ROUGHLY ALONG A KIRK TO KMKC LINE. CONVECTION DEVELOPING ON WESTERN FRINGE OF GREAT LAKES SHORTWAVE ALONG AND BEHIND SURFACE FRONT IS EVIDENT ACROSS EASTERN IA INTO IL. AIRMASS BEHIND FRONT REMAINS UNSTABLE WITH DEW POINTS IN THE LOWER 70S...AS DRIER AIR REMAINS FURTHER UPSTREAM ACROSS NORTHERN IA AND EASTERN NE. WILL KEEP 40 POPS ACROSS AREAS ALONG AND EAST OF A BETHANY TO SEDALIA LINE FOR THE EVENING HOURS. MESOANALYSIS INDICATES 30-40 KTS OF DEEP LAYER SHEAR PRESENTLY ACROSS THIS AREA WITH 100MB MLCAPE VALUES IN THE 1000-2000 J/KG RANGE...THUS CANT RULE OUT ISOLATED SEVERE POTENTIAL...WITH DAMAGING WINDS/HAIL THE THREATS. OTHERWISE EXPECT DRIER AIR TO WORK INTO THE AREA FOR SATURDAY. GOING TEMPS LOOK IN LINE WITH GUIDANCE...AND SHOULD RUN A FEW DEGREES BELOW NORMAL. SEAMAN FOR THE SUNDAY THROUGH WEDNESDAY TIMEFRAME...THE GENERAL UPPER PATTERN WILL CONSIST OF THE DOMINANT RIDGE OVER THE WESTERN CONUS AND TROUGH OVER THE EASTERN CONUS. THE PERSISTENT PATTERN KEEPS THIS FORECAST AREA UNDER THE NORTHWEST FLOW REGIME FOR MUCH OF NEXT WEEK. THE UPPER LOW OFF THE PACIFIC COAST WILL MOVE NORTHEAST AND ACROSS CENTRAL CANADA EARLY NEXT WEEK. THE UPPER LOW WILL BREAK DOWN THE NORTHERN PORTION OF THE RIDGE BEFORE SHEARING OUT. AS THIS ACTIVITY OCCURS ACROSS THE NORTHERN CONUS...TEMPERATURES HERE WILL SEE A WARMING TREND AS THE UPPER HIGH SPREADS OVER THE SOUTHERN CONUS THROUGH MID WEEK. A SURFACE FRONT IS THEN PROGGED TO MOVE SOUTHEAST TOWARD THE AREA ON WEDNESDAY. HAVE INTRODUCED CHANCES FOR SHOWERS AND THUNDERSTORMS WEDNESDAY NIGHT AHEAD OF THE ANTICIPATED FRONTAL PASSAGE ON THURSDAY. STOFLET && .PREV DISCUSSION... 406 AM... THIS MORNING A RIDGE REMAINS PARKED OVER THE ROCKY MOUNTAINS WITH A TROUGH AXIS ALONG THE APPALACHIAN MOUNTAINS. WITHIN THE NORTHWEST FLOW IN BETWEEN THESE TWO FEATURES A 100+ KTS JET STREAK AT 250 MB IS EVIDENT ON THE PROFILERS ACROSS THE UPPER MISSISSIPPI VALLEY. AN MCS OVER WEST KANSAS THIS MORNING HAS BROUGHT AN EFFECTIVE FRONT SOUTH...RUNNING IT FROM NORTH KANSAS THROUGH SOUTHEAST NEBRASKA INTO NORTH CENTRAL IOWA. RUC ANALYSIS INDICATES THAT A THETA-E AXIS IS A LITTLE TO OUR WEST...RUNNING FROM CENTRAL OKLAHOMA THROUGH KANSAS INTO EASTERN NEBRASKA. 00Z UPPER AIR SOUNDINGS FROM OAX...TOP...AND DVN ALL SHOWED A NICE CAP ACROSS THE CWA. HOWEVER...WITH 850 MB WINDS...WEAK AS THEY MAY BE...VEERING ACROSS THE THETA-E AXIS...AND THE RIGHT REAR ENTRANCE REGION OF THE JET SHIFTING SOUTH...CONVECTION HAS BEGUN TO FIRE ACROSS SOUTHWEST IOWA AND NORTHWEST MISSOURI THIS MORNING. FOR THE REMAINDER OF THE EARLY MORNING HOURS...THE CONVECTION WILL CONTINUE TO MOVE SOUTHEAST AT 45 MPH. WITH 0-6 KM SHEAR VALUES RUNNING IN THE 35+ KTS RANGE...AND SURFACE WINDS HIGHLY BACKED ALONG THE MISSOURI RIVER...LOCAL HELICITY VALUES ARE QUIT HIGH. HENCE SUPERCELL ACTIVITY WITH LARGE HAIL...DAMAGING STRAIGHT LINE WINDS...AND TORNADOS ARE POSSIBLE. AFTER SUNRISE...CONVECTION LOOKS TO BE ONGOING AS THE FORECAST BECOMES VALID THIS MORNING. THETA-E ADVECTION WILL CONTINUE ACROSS THE CWA AS THE RIGHT REAR ENTRANCE TO THE JET SETTLES THROUGH THE CWA TODAY. ADDITIONALLY...THE SHORTWAVE ASSOCIATED WITH THE JET STREAK WILL PUSH THE FRONT THROUGH NORTHERN MISSOURI EARLY THIS AFTERNOON PROVIDING A FOCUS FOR ACTIVITY. SURFACE BASED CAPES WILL BE RUNNING FROM AROUND 1000+ J/KG THIS MORNING TO 3000+ J/KG ALONG THE FRONT THIS AFTERNOON. 0-6 KM SHEAR VALUES ALSO RUN IN THE 30+ KNOT RANGE THROUGH THE AFTERNOON HOURS...SO HEAVY RAIN WIND AND HAIL AND WIND WILL BE POSSIBLE AS THESE STORMS WILL HAVE SOME ORGANIZATION AND HIGH PRECIPITABLE WATER VALUES. THEREFORE...I HAVE ADDED SOME LIKELY POPS TO THE FORECAST FOR THE MORNING AND AFTERNOON HOURS LOOSELY BASED ON THE EXPECTED SURFACE BOUNDARIES PROGRESS. OTHERWISE...I PUSHED TEMPERATURES DOWN A FEW DEGREES FOR THIS AFTERNOON AS THE SURFACE FRONT LOOKS TO PUSH THROUGH MOST OF THE CWA BY EARLY AFTERNOON AND THE CLOUD COVER FROM TODAYS CONVECTION SHOULD TAKE THE EDGE OF THE DIURNAL HEATING. CUTTER .PREV DISCUSSION... 910 PM THU... EARLY EVENING SATELLITE IMAGERY AND OBJECTIVE ANALYSIS INDICATE MID LEVEL RIDGE CENTERED OVER CENTRAL ROCKIES WITH 100+KT 250MB JET STREAK EMBEDDED WITHIN NORTHWEST FLOW ALOFT ACROSS UPPER/MID MS VALLEY. SURFACE ANALYSIS INDICATES COLD FRONT STRETCHING FROM EASTERN DAKOTAS BACK INTO WESTERN NEBRASKA...WHILE SURFACE RIDGE IN PLACE ACROSS EASTERN IA/MO. AHEAD OF SURFACE FRONT MOISTURE AXIS WITH LOW TO MID 70 DEW POINTS IN PLACE ACROSS EASTERN KS/NE...RESULTING IN AXIS OF >3000 J/KG 100MB MLCAPE...WHILE FURTHER EAST TIGHT INSTABILITY AXIS EXTENDS ACROSS WESTERN MO WHERE DEW POINTS FALL INTO THE LOWER TO MID 60S ACROSS CENTRAL/EASTERN MO ASSOCIATED WITH SURFACE RIDGE. TOP/OAX SOUNDINGS INDICATE FAIRLY SUBSTANTIAL CAPPING INVERSION REMAINS IN PLACE ACROSS THE REGION. SEVERE CONVECTION EARLIER THIS EVENING ACROSS SOUTHEAST SD/NORTHEAST NE WEAKENED RAPIDLY AS IT MOVED INTO EAST CENTRAL NE WHERE STRONGER CAP WAS IN PLACE...AND SCATTERED ELEVATED CONVECTION FURTHER EAST ACROSS IA REMAINS WEAK. ALTHOUGH CAPPING INVERSION REMAINS STRONG THIS EVENING...IT STILL APPEARS FORCING LATER TONIGHT WILL ALLOW FOR AT LEAST SCATTERED CONVECTION TO DEVELOP. AS JET STREAK PROPAGATES SOUTHWARD OVERNIGHT AND 850MB FLOW VEERS...EXPECT REGION OF ENHANCED LIFT TO SPREAD ACROSS WESTERN HALF OF FORECAST AREA...ASSOCIATED WITH COMBINATION OF RIGHT ENTRANCE REGION OF PASSING JET STREAK...AND 850MB THETA-E ADVECTION. THIS MAY BE SUFFICIENT TO WEAKEN CAP AND ALLOW PARCELS TO REACH LFC...ALLOWING FOR CONVECTION TO DEVELOP AND POSSIBLY BECOME WIDESPREAD ACROSS EASTERN KS/WESTERN MO AFTER 06Z. DEEP LAYER SHEAR IN EXCESS OF 40 KTS SUGGESTS STORMS HAVE POTENTIAL TO BECOME SEVERE...WITH DAMAGING WINDS THE MAIN THREAT. HIGH FREEZING/WET-BULB ZERO LEVELS WILL LIKELY KEEP HAIL THREAT MARGINAL AT BEST. GOING FORECAST LOOKS IN GOOD SHAPE AND HAVE ONLY MADE MINOR ADJUSTMENTS.
