AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 1250 PM CDT SAT JUN 21 2008 .DISCUSSION... /345 AM CDT SAT JUN 21 2008/ THE WEAK SHORT WAVE TROF MOVING THROUGH THE UPPER MS VLY ATTM IS FORECAST TO CONT MOVING ESEWD TODAY AND INTO THE GREAT LAKES BY EVENING...WITH THE ATTENDANT SFC BNDRY ACROSS SRN IA MOVING INTO SRN IL AND SE MO BY 00Z. AMPLE SUN/HEATING TODAY SHOULD RESULT IN DECENT INSTABILITY AHEAD OF THE BNDRY WILL MLCAPES AROUND 2000 J/KG. CONVERGENCE ALONG THE BOUNDARY HOWEVER WILL BE RELATIVELY WEAK AND DEEP LAYER SHEAR ONLY PROGGED TO BE AROUND 20-25 KTS...WHICH WOULD SUPPORT ISOLD-SCT COVERAGE OF PULSE TO MULTICELL STORMS. EXPECTING STORMS TO DEVELOP ALONG THE BOUNDARY THIS AFTERNOON WITH GREATEST COVERAGE ACROSS INDIANA/ILLINOIS DECREASING SWWD INTO MO. SOME MARGINALLY SEVERE HAIL AND WIND GUSTS COULD ACCOMPANY THE MOST INTENSE CELLS. OVERALL COVERAGE AND INTENSITY SHOULD DIMINISH THIS EVENING WITH LOSS OF HEATING AND AS THE STORMS MOVE SEWD AWAY FROM THE CWA. ATTENTION THEN TURNS TO THE POTENTIAL FOR ANOTHER ROUND OF STORMS DURING THE LATE EVENING AND OVERNIGHT HOURS FOCUSED BACK TO THE NORTH. A MUCH STRONGER SHRTWV TROF IS PROGGED TO DIG SEWD THRU THE MS VLY REGION BEGINNING LATE TONIGHT INTO SUNDAY WITH AN ATTENDANT COLD FRONT. A WESTERLY LLJ DEVELOPING AHEAD OF THE TROF/CDFNT TONIGHT WILL FOCUS WAA/LIFT ACROSS THE MO VLY REGION SUPPORTING THUNDERSTORM DEVELOPMENT. MODELS ARE SUGGESTING POTENTIAL FOR UPSCALE GROWTH INTO AN ORGANIZED CONVECTIVE COMPLEX MOVING INTO NRN MO. NOT SURE HOW FAR SOUTH THIS WILL GET BUT HAVE BUMPED UP POPS IN THE NORTH. ALSO INCREASED POPS A BIT ACROSS THE ENTIRE AREA ON SUNDAY AS THE MCS AND/OR RESIDUAL BNDRY AND CDFNT CONTS SEWD ACROSS THE REGION. DEEP LAYER SHEAR WILL BE MUCH IMPROVED DUE TO STRENGTHENING MID LEVEL FLOW ASSOCD WITH THE DIGG SHRTWV TROF AND THIS WOULD SUPPORT MUCH GREATER CONVECTIVE ORGANIZATION/COVERAGE. HIGH PRESSURE SHOULD THEN SETTLE INTO THE REGION ON MONDAY BRINGING A BRIEF SPELL OF DRY AND TRANQUIL WEATHER. GLASS && .AVIATION... /1239 PM CDT SAT JUN 21 2008/ FOR THE 18Z TAFS...A COLD FRONT THAT EXTENDS FROM NORTHEASTERN INDIANA THROUGH SOUTH CENTRAL ILLINOIS THEN INTO CENTRAL MISSOURI WILL SLIDE SOUTH THROUGH THE REST OF THE AREA BY THIS EVENING. THUNDERSTORMS ARE STILL EXPECTED TO DEVELOP ALONG AND BEHIND THE FRONT AS IT MOVES SOUTH. HOWEVER...THUNDERSTORMS ARE EXPECTED TO BE SCATTERED AND CHANCES OF THEM IMPACTING A TERMINAL ARE TOO REMOTE TO INCLUDE IN TAFS. OTHERWISE...WINDS ARE EXPECTED TO BE WESTERLY JUST AHEAD OF THE FRONT AND BECOME NORTHWEST TO NORTH BEHIND THE FRONT. MCS DEVELOPMENT STILL A POSSIBILITY OVER WESTERN IOWA TONIGHT WITH IT SLIDING SOUTHEAST TOWARDS TAF SITES...SO ADDED VCTS/VCSH TO SITES BEGINNING AROUND 09Z FOR KUIN...10Z FOR KCOU AND AROUND 12Z FOR KSUS/KSTL.
