AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 616 PM EDT SAT JUL 7 2012 .UPDATE... THE AVIATION SECTION HAS BEEN UPDATED BELOW && .SYNOPSIS... ISSUED AT 150 PM EDT SAT JUL 7 2012 HOT...DRY HIGH PRESSURE WILL PUSH SOUTH LATE TONIGHT AS A COLD FRONT SAGS ACROSS CENTRAL INDIANA. THE COLD FRONT WILL BRING AN END TO THE TRIPLE DIGIT HEAT...AND MAY ALSO PROVIDE A FEW SHOWERS OR THUNDERSTORMS AS IT PASSES. HOWEVER A DROUGHT-BUSTING SOAKER IS NOT EXPECTED. ANOTHER HIGH PRESSURE SYSTEM WILL BUILD ACROSS THE AREA IN THE WAKE OF THE FRONT. THIS SYSTEM WILL PROVIDE MUCH COOLER AIR FOR MUCH OF THE UPCOMING WORK WEEK AND ALLOW DAILY HIGH TEMPERATURES FALL BACK TOWARD SEASONAL NORMALS. && .NEAR TERM /TONIGHT/... ISSUED AT 150 PM EDT SAT JUL 7 2012 SURFACE ANALYSIS EARLY THIS AFTERNOON SHOWS BROAD HIGH PRESSURE STRETCHING FROM MISSOURI ACROSS INDIANA TO OHIO AND PA. A COLD FRONT WAS LOCATED ACROSS NORTHERN ILLINOIS AND SOUTHERN MICHIGAN...SLOWLY PUSHING SOUTHWARD. SOME LAKE BREEZE ENHANCEMENT WAS HELPING THE FRONT AROUND LAKE MICHIGAN. TEMPS WERE POISED TO REACH THE MIDDLE 100S TODAY. NO PRECIP ALONG THE FRONT AT THIS TIME AS WELL AS LITTLE CLOUD COVER ACCORDING TO VISIBLE PICTURES. WITH DAYTIME HEATING THIS AFTERNOON...EXPECT WIDELY SCATTERED SHOWERS AND THUNDERSTORMS TO CONTINUE THROUGH THE HEAT OF THE DAY...AND LINGER INTO THE EVENING HOURS AS SEEN IN PREVIOUS DAYS. HRRR FAILED TO DEVELOP ANY ORGANIZED CONVECTION NEAR THE FRONT...AND NAM HOLDS OFF DEVELOPMENT UNTIL AFTER MIDNIGHT. TIME HEIGHT SECTIONS DO BEGIN TO O SHOW LOWER AND MID LEVEL MOISTURE ARRIVING AFT 06Z WITH SOME LIFT. HOWEVER FORECAST SOUNDINGS FAIL TO SHOW SATURATION...BUT HINT AT JUST HEATING INSTABILITY. DYNAMICS ALOFT ARE WEAK. THUS CONFIDENCE IS QUITE LOW. WILL USE A BLEND OF THE MODELS FOR POPS. AS FOR TEMPS...COLD FRONT LOOKS TO STILL BE PASSING ACROSS THE FORECAST AREA LATE TONIGHT...AND FAR SOUTHERN COUNTIES MAY REMAIN IN THE WARM AIR MASS MUCH OF THE NIGHT. WILL TREND WARMER THAN MAVMOS FOR LOWS...ESPECIALLY GIVEN THE STARTING POINT WHERE WE HAVE TO FALL FROM LATE THIS AFTERNOON. && .SHORT TERM /SUNDAY THROUGH TUESDAY/... ISSUED AT 150 PM EDT SAT JUL 7 2012 MODELS ARE IN PRETTY GOOD AGREEMENT IN THE DURING THIS PERIOD AND WILL USE A BLEND. MAIN FORECAST CHALLENGE WILL BE POPS. FORECAST SOUNDINGS ON SUNDAY INDICATE A WARM AIR STILL LINGERING ALOFT...RESULTING IN AN INVERSION. FURTHERMORE TIME HEIGHTS CONTINUE TO SHOW GOOD MID LEVEL MOISTURE...WHICH LOOK TO BE CLUSTERS OF ICE CRYSTALS AND WATER VAPOR IN THE SKY...ALSO KNOWN AS CLOUDS. THE FRONTAL BOUNDARY WILL STILL BE LINGERING ACROSS THE SOUTHERN PARTS OF THE STATE...AND THIS MAY ACT AS AN EXTRA FORCING FEATURE ACROSS THE SOUTHERN PARTS OF THE FORECAST AREA. HOWEVER FORCING ALOFT REMAINS SLIM TO NONE AS THE STRONG RIDGE OVER THE WESTERN UNITED STATES BEGINS TO BUILD...SLOWLY BRINGING NORTHWESTERLY FLOW TO THE OHIO VALLEY. THUS WILL TRY TO KEEP A DRY FORECAST FOR SUNDAY...PARTICULARLY ACROSS THE NORTHERN PARTS OF THE FORECAST AREA WHERE DRY NE WINDS WILL BEGIN TO MAKE SOME HEADWAY. MAY NEED TO KEEP SOME LOW CHC POPS ACROSS THE SOUTH...AND AGAIN...A BIG RAIN WILL NOT BE EXPECTED TO LACK OF UPPER SUPPORT. GIVEN CLOUDS...WILL TREND HIGHS COOLER THAN MAVMOS. LITTLE CHANGE APPEARS TO OCCUR ON SUNDAY NIGHT AS THE FRONTAL BOUNDARY STALLS NEAR THE OHIO RIVER AND NE SURFACE FLOW CONTINUES ACROSS THE FA. NO SUPPORT ALOFT. WILL CONTINUE WITH A PERSISTENCE TYPE FORECAST WITH LOW CHC POPS ACROSS THE SOUTH AND DRY FORECAST ACROSS THE NORTH. GIVEN SOME EXPECTED CLOUDS IN THE AREA WILL TREND SUNDAY NIGHT LOWS WARMER THAN MAVMOS. MONDAY THROUGH TUESDAY THE BROAD COOLER HIGH PRESSURE SYSTEM OVER THE UPPER MIDWEST APPEARS TO FINALLY PUSH THE LINGERING FRONTAL BOUNDARY FARTHER SOUTH AS A COOLER AND DRY NE SURFACE FLOW PERSISTS. PARTLY CLOUDY DAYS AND MOSTLY CLEAR NIGHTS LOOK THE WAY TO GO AS FORECAST SOUNDINGS SHOW ATTAINABLE CONVECTIVE TEMPERATURES BUT DRY AIR ALOFT AND LITTLE CAPE. THUS WE WILL EXPECT JUST A FEW CU. WILL USE A BLEND ON TEMPS THROUGH THIS PERIOD. && .LONG TERM /TUESDAY NIGHT THROUGH WEDNESDAY/... ISSUED AT 158 PM EDT SAT JUL 7 2012 LATEST MODELS ARE IN RELATIVELY GOOD AGREEMENT...AND INDICATE DRY UNTIL AT LEAST SATURDAY. REGIONAL INITIALIZATION HAS A SMALL CHANCE OF PRECIPITATION FRIDAY AND FRIDAY NIGHT...BUT THE INITIALIZATION IS INFLUENCED BY PREVIOUS MODEL RUNS FOR CONTINUITY. CONSIDERING THIS AND ALSO MODELS TEND TO INTRODUCE PRECIPITATION TOO FAST IN A DROUGHT...GOING TOTALLY DRY FRIDAY AND FRIDAY NIGHT. TOO EARLY TO DISCARD SOMEWHAT HIGHER CHANCE OF RAIN REGIONAL MODEL HAS SATURDAY. FOR TEMPS...REGIONAL MODEL NOT ALL BAD BUT AS IWX POINTED OUT PROBABLY NEEDS TO BE BUMPED UP A LITTLE DAYS CONSIDERING EFFECTS OF DRY GROUND. && .AVIATION /DISCUSSION FOR 080000Z TAF ISSUANCE/... ISSUED AT 616 PM EDT SAT JUL 7 2012 VFR SCATTERED CLOUD COVER AND P6SM EXPECTED THROUGH THE PERIOD EXCEPT PERHAPS BRIEFLY IN A THUNDERSTORM. A WEAK FRONT IS EXPECTED TO BE NEAR LAF AROUND ISSUANCE TIME...IND AND HUF AROUND 02Z AND BMG AROUND 06Z. WINDS WILL BE AROUND 5 KNOTS OR LESS AND SWITCH FROM NORTHWEST TO NORTHEAST BEHIND THE BACKDOOR FRONT. PLENTY OF INSTABILITY FOR THUNDERSTORMS...BUT MOISTURE AND LIFT NO IMPRESSIVE...SO COVERAGE WILL NOT BE ENOUGH TO PUT IN THE TAFS UNLESS A STORM DEVELOPS NEAR A TAF SITE NEAR ISSUANCE TIME. THEN...MAY NEED TO ADD A SHORT VCTS OR TEMPO GROUP. WINDS WILL INCREASE TO 10 TO 15 KNOTS AFTER 15Z SUNDAY. && .IND WATCHES/WARNINGS/ADVISORIES... EXCESSIVE HEAT WARNING UNTIL 8 PM EDT THIS EVENING FOR INZ021- 028>031-035>049-051>057-060>065-067>072. && SYNOPSIS...PUMA NEAR TERM...PUMA SHORT TERM...PUMA LONG TERM....JK AVIATION...MK
