Area forecast discussion, Jun 1, 2:00 PM CST, 2 hours 28 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 300 PM CDT WED JUN 1 2011 .DISCUSSION... A WEAK WARM FRONT STRETCHING FROM MHK KANSAS SOUTHWEST TO SOUTHERN MISSOURI MARKS THE LEADING EDGE OF A HIGHLY UNSTABLE AIR MASS. STRONG THUNDERSTORMS WERE DEVELOPING ALONG THE LEADING EDGE OF THIS BOUNDARY. FOR THE MOST PART...THE STORMS HAVE BEEN BELOW SEVERE LIMITS DUE TO WEAK SHEAR. A FEW STORMS MAY PRODUCE MARGINALLY SEVERE HAIL AND DAMAGING WINDS...ESPECIALLY DUE TO THE PULSE NATURE OF THE CONVECTION. THE BOUNDARY WILL LIFT NORTHEAST THROUGH THE NIGHT WITH THE CONVECTION TO SLOWLY SPREAD NORTHEAST INTO WESTERN MISSOURI. STORMS MAY TEND TO DIMINISH TOWARD SUNSET. HOWEVER...WEAK ISENTROPIC LIFT MAY REGENERATE OR MAINTAIN CONVECTION ACROSS NORTHERN MISSOURI TONIGHT WITH MUCAPES AROUND 2000 J/KG. ALTHOUGH SHEAR WILL BE WEAK...A FEW STORMS MAY PRODUCE SMALL HAIL...GUSTY WINDS AND LOCALLY HEAVY RAINFALL. THE ISENTROPIC LIFT WILL END ACROSS NORTHERN MISSOURI THURSDAY MORNING WITH A MID LEVEL CAP SPREADING EAST INTO MISSOURI AS THE UPPER RIDGE BUILDS INTO THE PLAINS. THIS SHOULD PRECLUDE ADDITIONAL CONVECTION THROUGH AT LEAST FRIDAY. OTHERWISE...TEMPERATURES WILL CONTINUE TO WARM THROUGH FRIDAY WITH HEAT INDICES APPROACHING 100 DEGREES ON FRIDAY. DB MEDIUM RANGE (SAT-WED)... DEVELOPING MID-ATLANTIC BLOCKING WILL ALLOW THE SYNOPTIC FLOW PATTERN TO SLOW SIGNIFICANTLY OVER MUCH OF THE CONUS AS WE MOVE INTO AND THROUGH THE MEDIUM RANGE FORECAST. LONG RANGE MODELS REMAIN IN REASONABLE AGREEMENT ALLOWING A SUMMERLIKE UPR RIDGE TO DEVELOP OVER THE CONUS. CONDITIONS UNDER THIS RIDGE WILL BE TYPICAL TO THOSE OF JULY...WITH THE 588 DM RIDGE SUPPORTING UPR 80S TO LOWER 90S EACH AFTERNOON. A HIGHER SPIKE IN TEMPERATURES WILL BE PREVENTED BY THE RETURN OF RATHER OPPRESSIVE HUMIDITY VALUES AS DEWPOINTS CLIMB INTO THE UPPER 60S TO 70S EACH AFTERNOON THANKS IN PART TO INCREASING EVAPOTRANSPIRATION. HEAT INDEX READINGS MAY CLIMB INTO THE MIDDLE TO UPR 90S. REGARDING PRECIPITATION CHANCES...FORECAST SOUNDINGS CONTINUE TO SUGGEST MODEST CAPPING WHICH SHOULD PREVENT PRECIPITATION FOR MUCH OF THE AREA INTO NEXT WEEK. HOWEVER THE DEGREE OF SHORTWAVE ENERGY TRAPPED UNDER THE RIDGE...TYPICALLY A POOR FORECAST FOR MEDIUM RANGE MODELS...IS EXPECTED TO VARY FROM MODEL RUN TO MODEL RUN. ANY SHORTWAVE TRAPPED UNDER THE RIDGE GIVEN THE WEAK FLOW COULD PRODUCE SCT DIURNAL TSRA BY NEXT WEEK. DUX && .AVIATION... FOR THE 18Z TAFS...A WEAK WARM FRONT WHICH IS ALSO MARKS THE BETTER LOW LEVEL MOISTURE RETURN...WAS TRIGGERING SCATTERED SHOWERS AND THUNDERSTORMS IN NORTHEASTERN KANSAS. THE STORMS WERE LIFTING SLOWLY NORTHEAST. ALTHOUGH SHEAR IS QUITE WEAK...THE INSTABILITY AXIS WILL SHIFT SLOWLY EAST TOWARD THE TERMINALS LATE THIS AFTERNOON WITH A FEW STORMS POSSIBLY CLIPPING THE TERMINALS LATE THIS AFTERNOON AND EARLY THIS EVENING. LATER TONIGHT...THE FOCUS SHOULD BE TO THE NORTH AND EAST OF THE TERMINALS AS THE WARM ADVECTION AHEAD OF THE WARM FRONT SHIFTS NORTH. OTHERWISE...VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD.
