AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 1219 PM CDT SUN JUN 22 2008 .DISCUSSION... /335 AM CDT SUN JUN 22 2008/ UPSTREAM CONVECTION OVER SRN IA OR LACK THEREOF IS THE MOST PROBLEMATIC PART OF THIS FCST. IF THIS ACTIVITY WAS MAINTAINING ORGANIZATION AS IT MOVED SOUTHEAST IT WOULD MAKE A MORE SPECIFIC FCST A BIT EASIER. HOWEVER IN LIGHT OF THE RELATIVELY WEAK INFLOW/WAA INTO SRN IA/NRN MO...THE ACTIVITY HAS BEEN SHOWING A GENERAL WEAKENING TREND. SOUTH OF IT THERE IS ALOT OF ENHANCED HIGHER MID CLOUD...WHICH BEARS CAREFUL WATCHING. WHAT ALL THIS MEANS IS IT IS HARD TO SPECIFY THAT CONVECTION TODAY WILL BE PURELY CONFINED TO THE AFTERNOON AND EVENING HOURS. THAT SAID I THINK THE VAST MAJORITY WILL BE...BUT AGAIN CANT RULE OUT SOMETHING THIS MORNING. LATEST THINKING IS THAT THE WEAK BNDRY DRAPPED ACROSS IA WILL MOVE SOUTHEAST TODAY AS THE SHRTWV TROF PRESENTLY ACROSS THE UPPER MS VLY DIGS SEWD. MUCH LIKE YESTERDAY...CONVERGENCE ALONG THIS BNDRY WILL BE RELATIVELY WEAK AND MLCAPES EXPECTED TO APPROACH 2000 J/KG. THE ONE THING WE HAVE TODAY THAT WASNT PRESENT YDA IS MUCH GREATER DEEP LAYER SHEAR THANKS TO STRONGER MID LEVEL FLOW ASSOCIATED WITH DIGG TROF. THIS SHOULD PROMOTE OVERALL GREATER STORM ORGANIZATION AND IMPROVED SEVERE POTENTIAL. THE GENERAL SCENARIO I ENVISION IS SCATTERED THUNDERSTORMS DEVELOPING ALONG THE BNDRY THIS AFTERNOON BETWEEN ST LOUIS AND QUINCY...WITH THE ACTIVITY MOVING SSEWD. SHEAR IS SUFFICIENT FOR SHORT-LIVED SUPERCELLS AND MULTICELL CLUSTERS WITH AN ATTENDANT THREAT OF LARGE HAIL AND DAMAGING WINDS. THERE COULD BE A COUPLE OF CORRIDORS WHERE HYBRID MULTICELL CLUSTERS PRODUCE SWATHS OF DAMAGING WINDS. BOTH THE NCEP AND NSSL HI RES WRF MODELS ALSO FOLLOW THIS THINKING TO VARYING DEGREES. ACTIVITY SHOULD BE FOCUSED MAINLY FROM STL SOUTHWARD THIS EVENING AND I AM ANTICIPATING A GENERAL WEAKENING TREND AFTER SUNSET AS INSTABILITY DIMINISHES. DRIER AND SLIGHTLY COOLER AIR WILL FILTER INTO THE AREA ON MONDAY AS HIGH PRESSURE SETTLES INTO THE MS VLY...AND THIS SHOULD PERSIST INTO MONDAY NIGHT. TRANQUIL WEATHER HOWEVER APPEARS SHORT-LIVED. THE FAVORED WRF-NAM AND SREF HAS PRETTY DECENT WAA AND MOISTURE RETURN COMMENCING ON TUESDAY IN THE WAKE OF THE RETREATING ANTICYCLONE. IT APPEARS THAT SOMEWHERE ACROSS THE MID MS VLY THERE SHOULD BE A GOOD CHANCE OF SHOWERS AND THUNDERSTORMS GIVEN THESE FACETS...ALONG WITH MODERATE TO STRONG WARM SECTOR INSTABILITY AND A LIFTING WARM FRONTAL BNDRY. GLASS && .AVIATION... /1219 PM CDT SUN JUN 22 2008/ FOR THE 18Z TAFS...MID AND HIGH CLOUDS ASSOCIATED WITH SCATTERED SHOWERS AND A FEW THUNDERSTORMS WILL PERSIST OVER THE TAF SITES FOR THE FIRST 6 TO 8 HOURS OF THE FORECAST PERIOD. COULD STILL SEE ADDITIONAL SHOWERS AND THUNDERSTORMS DEVELOP AS A SHORTWAVE SLIDES THROUGH REGION...SO KEPT TEMPO GROUPS AT KCOU...KSTL AND KSUS FROM ABOUT 21Z TO 02Z. FEEL THAT MOST OF ACTIVITY TO REMAIN SOUTH OF KUIN...SO JUST HAVE VCTS THROUGH 01Z. BEYOND THAT...WILL SEE CLEAR SKIES AND LIGHT AND VARIABLE WINDS...WITH SOME DIURNAL CU DEVELOPING BY MID MORNING ON MONDAY. BYRD && .LSX WATCHES/WARNINGS/ADVISORIES... MO...NONE.
