AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
141 PM EDT THU JUN 9 2011

.UPDATE...
THE SYNOPSIS...NEAR TERM...SHORT TERM AND LONG TERM SECTIONS HAVE
BEEN UPDATED BELOW.

&&

.SYNOPSIS...A COLD FRONT ACROSS NORTHERN INDIANA EARLY THIS
AFTERNOON WILL SLIDE SOUTH TO SOUTH CENTRAL INDIANA BEFORE STALLING
THIS EVENING AND THEN LIFTING NORTH AS A WARM FRONT OVERNIGHT AND
FRIDAY. THEN...ANOTHER COLD FRONT WILL SLIDE SOUTHEAST ACROSS
CENTRAL INDIANA ON FRIDAY NIGHT AND SATURDAY. THE FRONTS WILL
INTERACT WITH AN UNSTABLE ATMOSPHERE TO PRODUCE SCATTERED TO
NUMEROUS THUNDERSTORMS. THEN...AFTER A BRIEF PERIOD OF DRY WEATHER
LATE IN THE WEEKEND...THUNDERSTORM CHANCES RETURN EARLY NEXT WEEK AS
THE FRONT RETURNS NORTHEASTWARD TOWARD THE OHIO VALLEY. THE HEAT
WAVE SHOULD BE ENDING BY SUNDAY AS TEMPERATURES FALL TO NEAR NORMAL
BEHIND THE SECOND COLD FRONT.

&&

.NEAR TERM /TONIGHT/...

MAIN CHALLENGE TONIGHT WILL BE POPS AS MODELS STILL HAVE
AFOREMENTION COLD FRONT STALLING OUT ACROSS SOUTH CENTRAL INDIANA
THIS EVENING AND LIFTING BACK NORTHEAST OVERNIGHT AND FRIDAY. PLENTY
OF INSTABILITY WILL BE AROUND TONIGHT WITH MIXED LAYER MODEL CAPES
FROM 500 TO 1500 J/KG. IN ADDITION...MODELS ALL HAVE A PRETTY DECENT
SHORT WAVE MOVING IN OVERNIGHT ON THE SOUTHERN END OF THE FAST
ZONAL FLOW ALOFT. ALSO...MODELS SHOWING DECENT LOW LEVEL CONVERGENCE
IN THE VICINITY OF THE FRONT AND DIVERGENCE ALOFT FROM UPPER JET
ACROSS THE GREAT LAKES. THUS...WILL GO WITH GOOD CHANCE OR BETTER
POPS TONIGHT ESPECIALLY ACROSS OUR NORTHERN COUNTIES CLOSER TO THE
850 MILLIBAR INFLOW AND OVERALL DEEPER MOISTURE. COULD SEE SOME
EVENING SEVERE STORMS...BUT LACK OF SHEAR SHOULD KEEP THEM ISOLATED.

THE WARMER NAM MOS LOOKS GOOD WITH THE LOWEST OVERNIGHT LOWS NORTH
IN THE 60S BEHIND THE FRONT.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...

MAIN FOCUS TO THE SHORT TERM WILL CONTINUE TO BE ON POPS AS A COLD
FRONT STALLS ACROSS SOUTH CENTRAL INDIANA THIS EVENING AND LIFTS
NORTHEAST OF THE FORECAST AREA FRIDAY AFTERNOON ONLY TO BE FOLLOWED
BY A COLD FRONT MOVING IN FROM THE WEST FRIDAY NIGHT.

MODELS FAR APART ON TIMING OF COLD FRONT. THE 12Z NAM AND 00Z ECMWF
HAVE IT ON THE SOUTHEASTERN FRINGES OF OUR FORECAST AREA 12Z
SATURDAY WITH THE 12Z OPERATIONAL GF...00Z GFS ENSEMBLE AND 09Z SREF
DONT HAVE IT THERE UNTIL 18Z SATURDAY. THE NAM AND GFS HAVE BEEN
FAIRLY CONSISTANT AND SO BLEND LOOKS LIKE THE WAY TO GO REGARDING
FRONTAL POSITION. MODELS WERE SHOWING PLENTY OF INSTABILITY WITH
MIXED LAYER CAPES TO AROUND 200 J/KG ON FRIDAY AND REMAINING ABOVE
1000 J/KG FRIDAY NIGHT AND SATURDAY SOUTHEAST. WILL KEEP HIGHEST
POPS THROUGH FRIDAY NIGHT NORTH CLOSEST TO THE 850 MILLIBAR INFLOW
AND DEEPER MOISTURE. THEN...SATURDAY...BEST POPS WILL BE SOUTHEAST
CLOSER TO THE FRONT TAPPERING TO SMALL CHANCE NORTHWEST. SHOULD SEE
THE ACTIVITY END BY SATURDAY EVENING WITH THE FRONT DROPPING FURTHER
SOUTHEAST AND DRIER AIR WORKING ITS WAY IN AS HIGH PRESSURE BUILDS
ACROSS THE WESTERN GREAT LAKES. COULD AGAIN SEE A FEW ISOLATED
SEVERE STORMS THROUGH SATURDAY...BUT WEAK SHEAR WOULD SUGGEST THEY
WOULD BE MAINLY DURING THE AFTERNOON AND EARLY EVENING HOURS.

MODEL BLEND LOOKS BEST FOR TEMPERATURES BASED ON EXACT FRONTAL
POSITION UNCERTAINTY.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...

LONG RANGE MODELS STILL A WAYS APART REGARDING THE TIMING OF THE
RETURN OF SATURDAY'S COLD FRONT BACK NORTHEASTWARD TOWARDS THE OHIO
VALLEY. THUS...CONFIDENCE LOW ON TIMING AND COVERAGE OF
THUNDERSTORMS NEXT WEEK. AGREE WITH HPC THAT SUNDAY SHOULD BE DRY
UNDER HIGH PRESSURE AND OTHERWISE LOWEST CHANCES WOULD SEEM TO BE
MONDAY AND TUESDAY WITH THE FRONT LIKELY TO BE FAR ENOUGH TO THE
SOUTHWEST...HOWEVER WITH MODELS NOT WELL IN SINK OR
CONSISTANT...WILL NOT MAKE ANY BIG CHANGES AND JUST KEEP SMALL POPS
IN EACH PERIOD NEXT WEEK AND FINE TUNE AS IT GETS CLOSER.
ALSO...MODELS DO SHOW A FEW SHORT WAVES DROPPING SOUTHEAST ACROSS
CENTRAL INDIANA OVERTOP A MISSISSIPPI VALLEY UPPER RIDGE...SO WOULD
HATE TO CUT POPS MONDAY AND TUESDAY JUST TO HAVE TO ADD THEM BACK.
HPC TEMPERATURES ARE SEVERAL DEGREES LOWER THAN PREVIOUS
FORECASTS...SO WILL NOT GO QUITE AS LOW. OVERALL...NEAR NORMAL
TEMPERATURES LOOK GOOD.

&&

.AVIATION.../DISCUSSION FOR 091800Z TAFS/...

LOW CONFIDENCE FORECAST THIS PACKAGE. THAT SAID...EXPECT GENERALLY
VFR CONDITIONS OUTSIDE OF CONVECTION...WITH EXCEPTION OF POSSIBLE
MVFR FOG OVERNIGHT IN FAVORED AREAS.

MAIN COLD FRONT REMAINS WELL TO THE NORTH OF THE SITES...BUT
NUMEROUS BOUNDARIES FROM PREVIOUS CONVECTION HAVE MOVED ACROSS THE
SITES. WIND DIRECTIONS VARY A LOT WITHIN RELATIVELY SHORT DISTANCES.
WITH A PASSAGE OF A BOUNDARY WINDS SHIFT QUICKLY. THUS WINDS MAY
VARY THIS AFTERNOON INTO THIS EVENING AT THE SITES. WILL GENERALLY
GO WITH PREVAILING E/SE WINDS...BUT SHIFTS TO THE NW OR NE CAN
HAPPEN QUICKLY WHEN A BOUNDARY PASSES.

THE SAME BOUNDARIES MAKE FORECASTING CONVECTION DIFFICULT. IN
GENERAL WILL USE SIMPLE CB MENTION...BUT ONE BOUNDARY MAY BE CLOSE
ENOUGH TO KIND AT ISSUANCE TIME TO GO WITH VCTS.

MORE STORMS WILL DEVELOP TONIGHT AND MOVE MAINLY TO THE NORTH OF THE
SITES...BUT AGAIN BOUNDARIES MAY WORK SOUTH INTO OUR AREA AND
TRIGGER CONVECTION. WILL CONTINUE CB MENTION. SIMILAR SCENARIO WILL
CONTINUE ON FRIDAY WITH FRONT/SCATTERED CONVECTION STILL IN THE
AREA.
