AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 1236 PM CDT SUN JUN 24 2012 .UPDATE... ISSUED AT 944 AM CDT SUN JUN 24 2012 ONGOING TSRA ACROSS ERN IA W CNTL IL HAVE BEEN DEVELOPING FURTHER TO THE W THAN PREVIOUSLY ANTICIPATED. IF THIS TREND CONTINUES...TSRA WILL BE POSSIBLE ACROSS EXTREME NERN MO. CURRENT STORMS ARE TRACKING SE AND SHUD AT LEAST IMPACT ADAMS...BROWN AND PIKE COUNTIES IN IL. UNCERTAINTY REMAINS HOW FAR S THESE STORMS WILL PERSIST BEFORE DISSIPATING...WHICH LEADS TO EVEN MORE QUESTIONS THRU THE AFTERNOON AND INTO THE EVENING HOURS. WILL CONTINUE TO MONITOR AND UPDATE LATER THIS MORNING AS THE LATEST MDL DATA BECOMES AVAILABLE. TILLY && .SHORT TERM... ISSUED AT 233 AM CDT SUN JUN 24 2012 (TODAY AND TONIGHT) EXPECT EARLY MORNING CONVECTION AND CLOUD COVER WILL MOVE EAST AND/OR DISSIPATE AS LLJ VEERS AND WEAKENS. SURFACE WARM FRONT SHOULD QUICKLY PRESS EAST ACROSS THE REGION WITH SOUTHWEST WINDS TAKING HOLD THIS AFTERNOON. STILL ON TRACK FOR ONE HOT DAY WITH HIGH TEMPERATURES IN THE MIDDLE TO UPPER 90S. STILL WOULDN'T BE SURPRISED IF A FEW LOCATIONS TOP 100 DEGREES...ESPECIALLY ACROSS SOUTHERN IOWA AND NORTHERN MISSOURI WHERE 850MB THERMAL RIDGE WILL RESIDE. HEAT INDEX VALUES TO REMAIN IN CHECK THIS AFTERNOON...WITH ONLY EXCEPTION BEING ACROSS NORTHEAST MISSOURI WHERE MOISTURE WILL BEGIN POOLING AHEAD OF THE FRONT DURING PEAK HEATING. HERE HEAT INDEX VALUES COULD CERTAINLY FLIRT WITH ADVISORY CRITERIA. THE UPPER AIR PATTERN WILL CONTINUE TO AMPLIFY AS A TROF DIGS ACROSS THE EASTERN CONUS AND RIDGE INTENSIFIES ACROSS THE PLAINS. THIS WILL CAUSE THE FLOW ALOFT TO BECOME MORE NORTHERLY OVER THE MIDWEST AND ALLOW A SURFACE COLD FRONT TO DROP SOUTH ACROSS THE AREA TONIGHT AND MONDAY MORNING. ATMOSPHERE WILL BECOME MODERATELY UNSTABLE THIS AFTERNOON ALONG AND AHEAD OF THE FRONT WHERE DEWPOINTS WILL POOL IN THE UPPER 60S AND LOWER 70S. RESPECTABLE AMOUNT OF 0-6KM SHEAR WILL AID THUNDERSTORM ORGANIZATION AND SEVERITY IF INITIATION CAN OCCUR. SPC HAS PLACED EXTREME NORTHEAST MISSOURI AND WEST CENTRAL ILLINOIS INTO A SLIGHT RISK TODAY AND TONIGHT. CURRENT THINKING IS THAT ISOLATED TO SCATTERED CONVECTION MAY DEVELOP ALONG THE FRONT LATE THIS AFTERNOON AND EVOLVE SOUTH AS CLUSTERS TOWARD THE I-70 CORRIDOR IN EXTREME EASTERN MISSOURI AND SOUTH CENTRAL ILLINOIS DURING THE EVENING. IF THESE STORMS DO IN FACT FORM...THEY WOULD BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING WINDS. CERTAINLY A CONDITIONAL RISK...BUT ONE THAT CANNOT BE IGNORED. LATEST MODEL RUNS HAVE SLOWED THE SOUTHWARD PROGRESS OF THE FRONT...LEADING TO MUCH WARMER TEMPERATURES AND HUMID CONDITIONS FOR TONIGHT. HAVE UTILIZED A BLEND OF 2M TEMPERATURES AND MOS GUIDANCE TO CAPTURE THIS TREND. HAVE ALSO MAINTAINED LOW END POPS OVERNIGHT DUE TO THE EXPECTED FRONTAL POSITION. CVKING && .LONG TERM... ISSUED AT 233 AM CDT SUN JUN 24 2012 (MONDAY THROUGH SATURDAY) CANADIAN HIGH PRESSURE WILL BUILD INTO THE MIDWEST BEHIND THE FRONT WITH COOLER AND DRIER CONDITIONS EXPECTED BY MONDAY AFTERNOON. GIVEN SLOWER SPEED OF FRONT HAVE ADDED A FEW DEGREES ONTO MONDAYS HIGHS. WEDNESDAY THROUGH SATURDAY... UPPER LEVEL RIDGE WILL BUILD BACK OVER THE MIDWEST BY MIDWEEK WITH A HEAT WAVE DEVELOPING ACROSS THE CWA THROUGH AT LEAST FRIDAY. HIGHS IN THE UPPER 90S AND LOWER 100S ARE EXPECTED. APPEARS THAT DEWPOINTS WILL REMAIN QUITE LOW WEDNESDAY AND THURSDAY WHICH WILL AGAIN KEEP HEAT INDEX VALUES BELOW ADVISORY CRITERIA. EXPECT DROUGHT CONDITIONS TO WORSEN CONSIDERABLY AS RAPID EVAPOTRANSPIRATION TAKES PLACE. SOME HINT IN GFS MODEL LAND THAT THE RIDGE WILL TRY TO FLATTEN OUT BY NEXT WEEKEND...WITH A FRONT SAGGING INTO AT LEAST THE NORTHERN PORTION OF THE CWA. NOT REALLY CONFIDENT THAT THIS WILL HAPPEN GIVEN THE SIZE OF THE UPPER LEVEL RIDGE. THEREFORE HAVE KEPT POPS OUT OF THE EXTENDED FORECAST. WILD CARD STILL REMAINS TROPICAL SYSTEM DEBBIE AND WHERE SHE GOES. LATEST ECWMF LOOKS SIMILAR TO THE EARLIER GEM SOLUTION OF BRINGING THE SYSTEM UP THE MISSISSIPPI RIVER. CVKING && .AVIATION... ISSUED AT 1223 PM CDT SUN JUN 24 2012 OUTFLOW FROM TSRA ACROSS IL CONTINUES TO MOVE S. SOME QUESTION IF THIS OUTFLOW WILL REACH SUS/CPS. WILL LEAVE TAF AS VRB EARLY THIS AFTERNOON FOR NOW. THIS OUTFLOW MAY BECOME A FOCUS FOR TSRA THIS AFTERNOON. STILL...EXPECT TSRA OVER N CNTL IL TO CONTINUE TO DEVELOP AND MOVE S THIS AFTERNOON. AS THESE TSRA APPROACH SRN PORTIONS OF IL...THEY MAY BEGIN TO MOVE/DEVELOP TO THE SW TWD AREA OF WEAKER CAP/MORE INSTABILITY AND TWD SUS/CPS. TOO MANY QUESTION REMAIN AT THIS POINT TO ADD TO TAF. UIN MAY ALSO SEE TSRA DEVELOPMENT THIS AFTERNOON...BUT AGAIN TOO MANY QUESTIONS REMAIN. COU IS EXPECTED TO REMAIN DRY THRU THE PERIOD. A CDFNT SHUD PUSH THRU THE TERMINALS LATE TONIGHT WITH NELY WINDS BEHIND THE FNT. THESE WINDS SHUD PICK UP SOMEWHAT LATE MON MORNING. SPECIFICS FOR KSTL...OUTFLOW CONTINUES TO APPROACH THE TERMINAL AND SHUD ARRIVE SHORTLY AFTER THE TAF BECOMES VALID. GUSTS UP TO 20 KTS MAY ACCOMPANY THIS GUST FRONT BUT SHUD DIMINISH QUICKLY. WINDS SHUD GRADUALLY VEER TO BECOME SELY LATER THIS AFTERNOON. HAVE KEPT TAF DRY FOR NOW AS DISCUSSED ABOVE. WINDS SHUD BECOME NELY LATE TONIGHT AS A CDFNT PASSES THRU THE REGION. THESE NELY WINDS SHUD PICK UP LATE MON MORNING TO AROUND 12 KTS. TILLY && .CLIMATE... ISSUED AT 233 AM CDT SUN JUN 24 2012 RECORD HIGHS FOR TODAY...WEDNESDAY...THURSDAY AND FRIDAY DATE ST.
