AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 155 AM CDT FRI MAY 28 2004 .DISCUSSION... STRONG SOUTHERN STREAM TROUGH CONTINUES TO ROTATE EASTWARD ACROSS THE SOUTHERN PLAINS EARLY THIS MORNING...WITH IMPRESSIVE SHORTWAVE RIDGE POISED TO BUILD OVER THE AREA LATER TODAY. REMNANTS OF EARLIER SUPERCELL EVENT OVER NRN MO HAD PUSHED SOUTH INTO THE OZARKS EARLY THIS MORNING WITH A BROKEN LINE OF WEAK THUNDERSTORMS DRAPED JUST BEHIND EFFECTIVE SURFACE COLD FRONT/OUTFLOW BOUNDARY WHICH IS MANIFESTED IN THE FORM OF A DEWPOINT GRADIENT. ACTIVE WEATHER PATTERN APPEARS LIKELY FOR THE WEEKEND. SHORT TERM (OVERNIGHT/TODAY)... LACK OF A SIGNIFICANT COLD POOL HAS RESULTED IN BROKEN CONVECTION BECOMING QUASI-STATIONARY OVER SRN MO...WITH TRAINING ACTIVITY CONTINUING OVER LAWRENCE COUNTY IN SW MO. THIS ACTIVITY IS BEING SUPPORTED BY A MODEST 20-30 KNOT LOW LEVEL JET OVER ERN OK/WRN AR AHEAD OF UPSTREAM TROUGH AXIS. EXPECT THIS ACTIVITY TO CONTINUE FOR SEVERAL MORE HOURS WITH BACK BUILDING EXPECTED AS LOW LEVEL FEED CONTINUES TO VEER. THIS WILL LIKELY LEAD TO LOCALIZED FLASH FLOODING WHERE BEST ORTHOGONAL FORCING IS MAXIMIZED OVER FAR SOUTHWEST MISSOURI. SUBSTANTIAL AVAILABLE ELEVATED CAPE WOULD YIELD MARGINALLY SEVERE HAIL IN THE STRONGEST CELLS AS WELL. SUBSIDENCE IN THE WAKE OF SOUTHERN STREAM SYSTEM WILL ALLOW IMPROVING CONDITIONS AFTER SUNRISE WITH MORNING MID-HIGH CLOUD COVER GIVING WAY TO INCREASING SUNSHINE. TEMPERATURES SHOULD REACH THE MID 80S MOST AREAS...BUT CONDITIONS WILL REMAIN QUITE MUGGY OVER SOUTHERN MISSOURI WHERE 70F DEWPOINTS WILL REMAIN POOLED SOUTH OF REMNANT CONVECTIVE OUTFLOW. DESPITE LACK OF MODEL QPF...I WOULD NOT BE SURPRISED IF A FEW SHOWERS/STORMS DEVELOPED OVER SRN MO WHERE DEEP MIXING CAN TAP INTO AN UNCAPPED AIRMASS -- QUESTION IS FORCING BUT THINK THAT LOW CHANCE POPS ARE WARRANTED. LONGER TERM (SATURDAY ONWARD).... CONDITIONS APPEAR TO BE COMING TOGETHER FOR A SIGNIFICANT SEVERE WEATHER EVENT ON SATURDAY IN OR CLOSE TO THE MISSOURI OZARKS REGION. PRONOUNCED SHORTWAVE RIDGING OVER THE CENTRAL CONUS WILL SLIDE EAST DURING THE EARLY MORNING HOURS SATURDAY...ALLOWING FOR SHARP HEIGHT FALLS TO SPREAD EAST OVER THE PLAINS AS LEAD NEGATIVE TILT SHORTWAVE TROF EJECTS OUT FROM UNDERNEATH VIGOROUS UPPER LEVEL CYCLONE OVER THE NORTHERN ROCKIES. RESULTING STRONG LEE CYCLOGENESIS AND SYNOPTICALLY FORCED LOW LEVEL WIND MAXIMA WILL PROMOTE MODEST WARM AIR ADVECTION AND FUNNEL RICH LOW LEVEL MOISTURE (DWPTS AROUND 70F) NORTHWARD BACK INTO THE REGION DURING THE DAY. WARM SECTOR WILL ONLY BE WEAKLY CAPPED OVER THE OZARKS AS MODEL PROGS MAINTAIN ELEVATED MIXED LAYER WEST OF THE REGION. STILL...A MODERATE TO VERY UNSTABLE AIRMASS IS EXPECTED TO BUILD OVER A GOOD PORTION OF THE OZARKS REGION BY AFTERNOON. MEANWHILE...STRONG PRESSURE FALLS WILL RESULT IN INCREASINGLY BACKED LOW LEVEL FLOW WHICH WILL BE LOCALLY ENHANCED ALONG SURFACE WARM FRONT...WITH HIRES ETA ALSO SHOWING STRONG SIGNS OF A SECONDARY OROGRAPHICALLY INDUCED TROUGH DEVELOPING LEE OF THE BOSTON MOUNTAINS. VERTICAL SHEAR WILL INCREASE SHARPLY THROUGHOUT THE DAY AS MID-UPPER LEVEL JET STREAKS TRANSLATE THROUGH THE MEAN TROUGH AXIS...RESULTING IN LARGE SWEEPING HODOGRAPHS OVER THE WRN OZARKS AND ERN PLAINS BY LATE AFTERNOON. AT THIS POINT...THE COMBINATION OF INSTABILITY AND STRONG DIRECTIONAL/SPEED SHEAR HIGHLY FAVORABLE FOR THE DEVELOPMENT OF SUPERCELL THUNDERSTORMS OVER THE AREA SATURDAY...ESPECIALLY DURING THE AFTERNOON AND EVENING HOURS. THE EVENT MAY UNFOLD WITH EARLY CONVECTION FIRING ALONG THE RETREATING WARM FRONT...AND THEN ADDITIONAL SUPERCELL THUNDERSTORMS DEVELOPING OVER THE EASTERN PLAINS ALONG THE ADVANCING DRY LINE. WILL CONTINUE TO MONITOR TRENDS THROUGH TOMORROW MORNING...BUT AT THIS POINT HAVE HIGH CONFIDENCE THAT VERY LARGE HAIL...DAMAGING WINDS AND TORNADOES WILL BE POSSIBLE IN OUR JUST WEST OF THE AREA. CONDITIONS FOR SUNDAY HARDLY AN IMPROVEMENT AS VIGOROUS VORTICITY LOBE AND AN EQUALLY POTENT NEGATIVE TILT SHORTWAVE TROUGH ROTATE NORTHEAST AHEAD OF SLOW MOVING SYSTEM OVER THE NORTHERN PLAINS. AFTER A BRIEF RESPITE IN THE WARM SECTOR SUNDAY...CONDITIONS APPEAR FAVORABLE FOR AN EXTENSIVE SQUALL LINE TO AFFECT A LARGE PORTION OF THE NATIONS MID SECTION AS IMPRESSIVE SYNOPTIC SCALE LINEAR FORCING ACCOMPANIES ADVANCING SURFACE FRONT. WILL NOT BUY INTO ADDITIONAL HIGH QPF AMOUNTS BEING ADVERTISED BY THE GFS ON MEMORIAL DAY...HOWEVER WILL HAVE TO MONITOR TRENDS TO INTRODUCE AT LEAST LOW CHANCE POPS AS SHARP POST-FRONTAL SURFACE TROUGH REMAINS OVER THE MID WEST WHILE FINALLY SPOKE OF ENERGY ALOFT ROTATES SOUTHEAST INTO THE AREA MONDAY WITHIN INCREASING NORTHWEST FLOW ALOFT. MUCH DRIER AIRMASS TO FINALLY MAKE ITS PRESENCE KNOWN TUESDAY INTO THE MIDDLE OF NEXT WEEK. && .AVIATION... CONVECTIVE CHANCES HAVE BEEN REINTRODUCED INTO THE KSGF TAF FOR EARLY THIS MORNING AS LOW LEVEL JET FORCING CONVECTION IN THE WAKE OF WEAK LOW LEVEL GUST FRONT EARLIER. CIGS/VIS TO REMAIN VFR THROUGH THE PERIOD AT KSGF TERMINAL EXCEPT FOR TEMPORARY LIFR VSBYS IN VICINITY OF EARLY MORNING THUNDERSTORMS. AT JOPLIN...BROKEN MVFR CIGS ARE VERY LOCALIZED AND SEEM TO BE DRIVEN BY SIGNIFICANT LOW LEVEL MOISTURE (74F DEWPOINT) BEING POOLED JUST SOUTH/WEST OF CONVECTION TO THEIR NORTHEAST. DO NOT ENVISION THIS BEING LONG LIVED AND WILL IMPROVE TO VFR CONDITIONS DURING HOURS OF AIRPORT OPERATIONS. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. BOOKBINDER
