AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 318 PM CDT MON MAY 22 2006 .DISCUSSION... MESOSCALE CONVECTIVE VORTEX OVER SOUTHERN KANSAS CONTINUES TO MOVE EVER SO SLOWLY EASTWARD WITH AN ARC OF WHAT APPEARS TO BE ELEVATED CONVECTION (PER SPC MESOANALYSIS GRAPHICS) OCCURRING ALONG ITS LEADING EDGE. REMNANT SURFACE BOUNDARY STRETCHING FROM BOURBON COUNTY SE INTO LAWRENCE AND STONE COUNTY SHOWS UP QUITE NICELY IN AWS OBSERVATIONS WITH A SLIGHTLY MORE ENHANCED CUMULUS FIELD DEVELOPING ALONG THE CONVERGENCE AXIS. MOISTURE APPEARS TO BE POOLING A BIT JUST TO THE NORTH OF THIS CONVERGENCE AXIS WITH DEWPOINTS IN THE LOWER 70S LEADINGS TO MLCAPES OF NEARLY 3000 J/KG BASED OFF MODIFIED RUC POINT FORECAST SOUNDINGS. WHILE INSTABILITY IS PLENTIFUL SHEAR IS PITIFUL WITH WINDS AT OR BELOW 15KT FROM THE SURFACE TO 250MB. ANY STORMS THAT CAN DEVELOP ALONG THIS CONVERGENCE AXIS LATE THIS AFTERNOON INTO EARLY THIS EVENING MAY POSE A BRIEF LOCALIZED WIND/MARGINAL HAIL THREAT. CONVECTION WILL BY AND LARGE BEGIN TO DIMINISH AFTER SUNSET HOWEVER WITH SOME CONVECTION STILL PRESENT NEAR THE MCV OVER KS ITS POSSIBLE THAT THIS FEATURE MAY SUSTAIN ITSELF INTO THE NIGHT LEADING TO AT LEAST SOME SMALL CHANCES OF SHOWERS/ISO STORMS INTO TUESDAY MORNING AS IT TRANSLATES SLOWLY EASTWARD. ASSUMING THIS MCV MAINTAINS ITS IDENTITY OVERNIGHT INTO TUESDAY WE WILL END UP ON THE SUBSIDENT BACKSIDE OF THE VORT TUESDAY AFTERNOON WITH MORE SUNSHINE EXPECTED. AT LEAST MIXED SUNSHINE AND SOUTHERLY WINDS SHOULD ALLOW TEMPS TO WARM WELL INTO THE 80S AND HAVE TRENDED TEMPS A SMIDGE ABOVE THE WARMEST OBJECTIVE GUIDANCE FOR TUESDAY AFTERNOON. VIGOROUS NEGATIVE TILT TROUGH OVER SOUTHERN CALIFORNIA INTO ARIZONA WILL MOVE NORTHEASTWARD ACROSS THE ROCKIES TUESDAY AND INTO THE EASTERN PLAINS/MID MISSISSIPPI VALLEY REGION BY WEDNESDAY AFTERNOON. SURFACE FRONT IS PROGGED TO DROP INTO THE OZARKS WEDNESDAY AFTERNOON WITH FULL SUITE OF SHORT RANGE NUMERICAL GUIDANCE IN GOOD AGREEMENT ON TIMING AND PLACEMENT OF FRONTAL BOUNDARY. NAM/GFS/WRF ALSO ALL TIGHTEN THE HEIGHT GRADIENT TO THE SOUTH OF THE CLOSED LOW TO OUR NORTH AND LEAD TO FAIRLY MODEST MID LEVEL FLOW AND SOMEWHAT IMPRESSIVE DEEP LAYER SHEAR VALUES. ASSUMING NO CONVECTIVE DEBRIS LEFT OVER FROM ANY UNEXPECTED NOCTURNAL CONVECTION WEDNESDAY MORNING WE SHOULD BECOME QUITE UNSTABLE WEDNESDAY AFTERNOON. AT THIS DISTANCE SET UP APPEARS FAVORABLE FOR SEVERE WX WEDNESDAY AFTERNOON INTO WED NIGHT AND HAVE HIT THIS IN THE HWO A BIT. NAM/GFS BOTH BLAST THE FRONT SOUTH OF THE CWA BY THURSDAY MORNING...HOWEVER WRF HANGS THE FRONT UP OVER SOUTHERN MISSOURI AND WOULD SUGGEST A CONTINUED THREAT OF SHRA/TSRA OVER SOUTHERN MISSOURI INTO THURSDAY AFTERNOON. WILL NEED TO KEEP AN EYE ON THIS IN LATER RUNS BUT ONLY KEPT SOME SCHC POPS GOING JUST IN CASE THE WRF PANS OUT. IN THE EXTENDED UPPER RIDGE BUILDS INTO THE AREA AND SHOULD SET THE STAGE FOR MUCH ABOVE AVERAGE TEMPERATURES (POSSIBLY NEAR RECORD BREAKING) LATE IN THE WEEK INTO THE WEEKEND. CONVECTIVE CHANCES LOOK PRETTY LOW DURING THAT TIME FRAME AS WARM MID LEVEL TEMPS BENEATH THE UPPER RIDGE SHOULD KEEP CONVECTION GENERALLY SUPPRESSED. RIDGE MAY BEGIN TO BREAK DOWN BY EARLY NEXT WEEK BUT THAT IS TEETERING ON THE EDGE OF PREDICTABILITY THIS FAR IN ADVANCE SO ONLY NUDGED POPS A BIT ABOVE CLIMO AND TEMPS A BIT COOLER TOWARD CLIMO. IZZI && .AVIATION... THUNDERSTORMS WILL LIKELY AFFECT BOTH KJLN AND KSGF THIS AFTERNOON...AND INTO THE EARLY EVENING. SCATTERED SHOWERS MAY ALSO LINGER NEAR THE TERMINALS THROUGH 02-03Z. WINDS SHOULD GO CALM TONIGHT...AS SKIES CLEAR OUT. GIVEN THE ALREADY MOIST ATMOSPHERE AND ADDITIONAL MOISTURE FROM RAINFALL TONIGHT...FOG WILL ONCE AGAIN BE POSSIBLE DURING THE EARLY MORNING HOURS. HAVE TAKEN KSGF INTO MVFR FOR VISIBILITY AFTER 06Z...BUT KEEPING KJLN IN VFR AT THIS TIME. CURRENT THINKING IS THAT THE FOG WILL MOST LIKELY BE A PLATEAU EFFECT...BUT VISIBILITIES AT KJLN WILL NEED TO BE CLOSELY MONITORED. CONDITIONS LOOK DRY AND VFR FOR TUESDAY...WITH SOUTHERLY WINDS GUSTING TO NEAR 20KTS BY EARLY AFTERNOON. SCHULTZ && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. WFO SGF
