AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 256 AM EDT TUE JUL 24 2012 .UPDATE... THE SYNOPSIS...NEAR TERM AND SHORT TERM SECTIONS HAVE BEEN UPDATED BELOW && .SYNOPSIS... ISSUED AT 245 AM EDT TUE JUL 24 2012 A COLD FRONT WILL DROP SOUTH ACROSS CENTRAL INDIANA TODAY BEFORE RETURNING NORTHEAST AS A WARM FRONT TUESDAY NIGHT AND WEDNESDAY. ANOTHER COLD FRONT WILL DROP SOUTHEAST FROM THE UPPER MIDWEST ON FRIDAY AND FRIDAY NIGHT BEFORE LIFTING NORTHEAST AS A WARM FRONT INTO SOUTHWEST INDIANA EARLY NEXT WEEK. THIS WILL RESULT IN THUNDERSTORM CHANCES THROUGH THE REMAINDER OF THE WORK WEEK AND MORE CHANCES LATE IN THE WEEKEND AND EARLY NEXT WEEK. THE LATTER FRONT WILL BRING IN MORE SEASONABLE TEMPERATURES FOR THE WEEKEND BUT NOT BEFORE AFTERNOON TEMPERATURES IN THE 90S OR ABOVE CONTINUE THROUGH LATE THIS WORK WEEK. && .NEAR TERM /TODAY/... ISSUED AT 245 AM EDT TUE JUL 24 2012 MAIN ISSUES OF CONCERN FOR CENTRAL INDIANA TODAY ARE THUNDERSTORM CHANCES...INCLUDING SEVERE POSSIBILITY...AND THE SEEMINGLY NEVER ENDING HEAT ISSUES. MODELS IN PRETTY DECENT AGREEMENT ON DROPPING A COLD FRONT...CURRENTLY ACROSS SOUTHERN LOWER MICHIGAN...ACROSS CENTRAL INDIANA TODAY. THE FRONT IS EXPECTED TO INTERACT WITH AN UNSTABLE ATMOSPHERE AND PRODUCE SCATTERED THUNDERSTORMS THROUGH THE DAY WITH THE BEST CHANCES ACROSS NORTHEAST SECTIONS...WHERE THE MOISTURE WILL BE DEEPER. THIS AREA WILL ALSO BE CLOSER TO THE BETTER UPPER DYNAMICS AS A 90 PLUS JET STREAK AT 250 MILLIBARS WILL BE NORTHWEST AND SOUTHEAST ORIENTED ACROSS THE EASTERN GREAT LAKES. GOOD MID LEVEL FLOW FOR THIS TIME OF YEAR ALONG WITH A 30 PLUS KNOT LOW LEVEL JET WILL BE NEAR OUR NORTHEAST AS WELL. THIS AREA WILL ALSO BE WITHIN A WARM AIR ADVECTION ZONE WHICH SHOULD PROVIDE ADDITIONAL LIFT. MIXED LAYER CAPES FROM THE NAM12 SOUNDINGS EXCEED 2500 J/KG THIS AFTERNOON NEAR THE FRONT. WITH STRONG INSTABILITY AND MORE THAN SUFFICIENT UPPER DYNAMICS...WOULD NOT BE SURPRISED TO SEE A FEW SEVERE STORMS PER THE SPC DAY1 OUTLOOK ALONG AND NORTH OF THE FRONT. UNIDIRECTIONAL NORTHWEST FLOW SUGGESTS WIND DAMAGE AND LARGE HAIL WOULD BE THE MAIN SEVERE THREATS. AFTERNOON HEAT INDICES LOOK LIKE THEY WILL REACH HEAT ADVISORY CRITERIA SOUTHWEST THIS AFTERNOON...WHERE MORE SUNSHINE IS EXPECTED. TEMPERATURES AND HEAT INDICES ACROSS THE NORTHEAST HALF OR SO OF THE FORECAST WILL BE MORE PROBLEMATIC AND DEPEND ON THE THUNDERSTORM COVERAGE ALONG WITH ASSOCIATED CLOUD COVER AND HOW FAR SOUTHWEST THE FRONT MAKES IT. BEST BET IS TOO STICK CLOSER TO...BUT A DEGREE OR TWO WARMER THEN THE WARMER NAM MOS SOUTHWEST AND NEAR THE NAM MOS NORTHEAST. AT ANY RATE...WILL GO WITH A HEAT ADVISORY STARTING AT NOON ACROSS SOME OF OUR SOUTHWEST COUNTIES AND CONTINUE IT THROUGH WEDNESDAY THERE. && .SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/... ISSUED AT 245 AM EDT TUE JUL 24 2012 THE FOCUS FOR THE SHORT TERM WILL CONTINUE TO BE ON THUNDERSTORM CHANCES ALONG WITH TEMPERATURES AS THE COLD FRONT TODAY IS EXPECTED TO LIFT BACK NORTH OVERNIGHT TONIGHT AND INTO WEDNESDAY BEFORE ANOTHER APPROACHES DROPS SOUTHEAST TO LAKE MICHIGAN AND NORTHERN ILLINOIS OVERNIGHT THURSDAY NIGHT PER THE MORE CONSISTENT 12Z ECMWF AND THE 00Z GFS AND GEFS. AGAIN...PLENTY OF INSTABILITY THROUGH THE PERIOD...BUT BEST CHANCES APPEAR TO BE THURSDAY AFTERNOON AND NIGHT AS THE LATTER FRONT GETS CLOSER AND IS HELPED ALONG BY FAST ZONAL OR NORTHWEST UPPER FLOW AROUND THE BASE OF AN UPPER LOW THAT IS EXPECTED TO OPEN UP OVER THE NORTHERN WISCONSIN AND LAKE SUPERIOR VICINITY EARLY FRIDAY. WILL STICK WITH GOOD CHANCE POPS FOR THIS TIME PERIOD. LOWEST POPS LOOK TO BE LATE WEDNESDAY AND WEDNESDAY NIGHT AS THE FIRST FRONT LIFTS NORTHEAST OF THE FORECAST AREA AND 700 MILLIBAR TEMPERATURES AROUND 12 DEGREES SUGGEST THE ATMOSPHERE WILL BE CAPPED. AFTER COORDINATION WITH ADJACENT OFFICES...WILL GO DRY FOR THAT TIME PERIOD. WITH THE FORECAST AREA IN THE WARM SECTOR ON WEDNESDAY...SHOULD SEE A GOOD DEAL OF SUNSHINE. ALSO...850 MILLIBAR TEMPERATURES ARE PROGGED TO BE AROUND 26 DEGREES CELSIUS. THIS SHOULD ALLOW TEMPERATURES TO APPROACH TRIPLE DIGITS NORTHEAST AND EASILY EXCEED 100 DEGREES SOUTHWEST PER THE HOTTER 00Z NAM MOS. THE 00Z GFS MOS AGAIN LOOKS LIKE IT IS NOT BE ABLE TO HANDLE DROUGHT RELATED LACK OF VEGETATIVE MOISTURE AVAILABLE. DESPITE CONVECTIVE MIXING OF DRIER AIR TO THE SURFACE...DEW POINTS IN THE WARM SECTOR HAVE STAYED UP TO MID AND UPPER 60S OF LATE. SO...TEMPERATURES 100 DEGREES AND ABOVE ALONG WITH MID AND UPPER 60S DEW POINTS WILL RESULT IN HEAT INDICES NEAR 105 WHICH IS ENOUGH TO GO WITH A HEAT ADVISORY WEDNESDAY FROM NOON TO 8 ACROSS ALL THE COUNTIES THAT ARE NOT IN THE ONE FOR TODAY. WOULDN'T RULE OUT ANOTHER HEAT ADVISORY ON THURSDAY...BUT FOR NOW...WITH COVERAGE OF THUNDERSTORMS AND CLOUD COVER STILL A BIT UP IN THE AIR...WILL WITHHOLD HEADLINES. && .LONG TERM /FRIDAY THROUGH TUESDAY/... ISSUED AT 241 AM EDT TUE JUL 24 2012 GUIDANCE IN DECENT AGREEMENT EARLY IN THE LONG TERM PERIOD WITH A COLD FRONT HAVING EXITED THE AREA...AND A TRAILING UPPER WAVE ON ITS WAY OUT AS WELL. WILL HAVE LOW POPS INITIALLY WITH THIS WAVE...FOLLOWED BY A PERIOD OF DRY WEATHER AS A SURFACE HIGH TRAVERSES THE AREA FRIDAY NIGHT TRHOUGH SUNDAY. INITIALIZATION REINTRODUCES POPS SUNDAY NIGHT THROUGH THE REMAINDER OF THE PERIOD WITH HINTS OF AN UPPER LEVEL WAVE ROUNDING THE RIDGE TO THE WEST. WITH GREATER UNCERTAINTY AND MODEL DISCREPANCY REGARDING THIS PERIOD...HAVE CUT INITIALIZATION POPS TO NO MORE THAN 30 PERCENT. INCREASED MAX TEMPS ACROSS THE BOARD A DEGREE OR SO...AS ALLBLEND HAS ROUTINELY SUFFERED FROM A BIT OF A COOL BIAS LIKELY OWING TO GFS INFLUENCE. && .AVIATION /DISCUSSION FOR THE 24/06Z TAFS/... ISSUED AT 110 AM EDT TUE JUL 24 2012 THIS EVENING/S UPPER AIR INDICATES AIR MASS STILL QUITE FAVORABLE FOR CONVECTION. MODEST 15-20KT LOW LEVEL JET COMBINED WITH FRONTAL SYSTEM DROPPING DOWN FROM THE NORTH...SHOULD ALLOW FOR SCATTERED CONVECTION TO DEVELOP AFTER ABOUT 250800Z OR SO. KLAF APPEARS TO HAVE THE BEST CHANCES FOR A DIRECT IMPACT FROM CONVECTION...WITH PROGRESSIVELY LESSER CHANCES WITH THE MORE SOUTHERN TAF SITES. DUE TO THE NOCTURNAL NATURE OF THE CONVECTION...CB BASES SHOULD BE RATHER HIGH...AROUND 050. CONVECTIVE THREAT EXPECTED TO DIMINISH BY THE MID MORNING HOURS ON TUESDAY AS LOW LEVEL FLOW WEAKENS. OUTSIDE OF ANY CONVECTION...CEILINGS GENERALLY ABOVE 050...SURFACE WINDS LESS THAN 12 KTS EXPECTED AT THE TAF SITES THROUGH 241800Z. PROBABLY WILL SEE SOME DIURNAL CLOUD DEVELOPMENT BASED 020-030 BY THE MID TO LATE MORNING HOURS TUESDAY. && .IND WATCHES/WARNINGS/ADVISORIES...
