AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
158 PM EDT FRI OCT 28 2011

.UPDATE...
THE LONG TERM SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...

A COOL BUT QUIET WEATHER PATTERN IS EXPECTED THIS
WEEKEND AS NORTHWEST FLOW ALOFT WILL PUSH A COUPLE OF UPPER LEVEL
WEATHER DISTURBANCES THROUGH INDIANA. THE FIRST SYSTEM WILL PUSH
THROUGH TONIGHT...AND WILL MAINLY RESULT IN JUST AN INCREASE IN
CLOUDS. THE NEXT WILL PUSH THROUGH ON SUNDAY NIGHT AND MONDAY AND
WILL RESULT IN OUR NEXT BEST CHANCE FOR RAIN. DRY WEATHER IS THEN
EXPECTED EARLY NEXT WEEK IN THE WAKE OF THAT SYSTEM.

RAIN CHANCES WILL THEN RETURN LATE NEXT WORK WEEK AS ANOTHER COLD
FRONT IS EXPECTED TO PUSH ACROSS THE REGION. TEMPERATURES ARE
EXPECTED TO BE NEAR NORMAL.

&&

.NEAR TERM /TONIGHT/...

A WEAK SHORT WAVE OVER THE UPPER MIDWEST IS EXPECTED TO PIVOT
SOUTHEASTWARD ACROSS NORTHERN INDIANA AND THE SOUTHERN GREAT LAKES
LATE TONIGHT. VERY DRY AIR REMAINED IN PLACE AT THE SURFACE AS DEW
POINT TEMPERATURES WERE IN THE LOWER 30S. TIME HEIGHT SECTIONS
TONIGHT SHOW SOME WEAK LIFT...BUT AGAIN MOISTURE REMAINS LIMITED.
FORECAST SOUNDINGS REMAIN RATHER DRY BUT DO SHOW SOME MID LEVEL
SATURATION TOWARD 12Z INDICATIVE OF CLOUD COVER. HOWEVER PERIODS
OF CLEAR SKIES AND EXPECTED LOWS IN THE MIDDLE AND LOWER 30S
SHOULD BE ENOUGH FOR AREA OF FROST IN SOME SPOTS...PARTICULARLY
ACROSS THE SOUTHERN PARTS OF THE FORECAST AREA WHERE CLOUD COVERAGE
FROM THE PASSING SYSTEM TO THE NORTH WILL HAVE ITS LEAST
INFLUENCE. THUS WILL INCLUDE ANOTHER FROST ADVISORY TONIGHT. ALSO
WILL TRIM MAVMOS LOWS BY 1-2 DEGREES...PARTICULARLY ACROSS THE
SOUTHERN FORECAST AREA WHERE CLOUD COVERAGE IS EXPECTED TO BE LOWEST.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY/...

MODELS REMAIN IN PRETTY GOOD AGREEMENT AND WILL USE A BLEND. MAIN
FORECAST CHALLENGE WILL BE TEMPERATURES IN ON SATURDAY AND
SUNDAY...AND RAIN CHANCES ON SUNDAY NIGHT INTO MONDAY.

NAM/GFS SHOW TONIGHTS SHORT WAVE QUICKLY DEPARTING ON SATURDAY
MORNING AND FORECAST SOUNDINGS DRY OUT QUICKLY. GOOD SUBSIDENCE IS
ALSO SEEN IN THE TIME HEIGHT SECTIONS. THUS WILL TREND TOWARD
PARTLY CLOUDY ON SATURDAY AS A SURFACE RIDGE OF HIGH PRESSURE
BUILDS ACROSS THE AREA. GIVEN THE 850MB TEMPERATURES A BLEND OF
MAVMOS AND METMOS WILL WORK NICELY.

HIGH PRESSURE QUICKLY MOVES THROUGH THE SATE ON SATURDAY NIGHT AND
DRY WEATHER IS EXPECTED. HOWEVER CLOUDS WILL INCREASE LATE
SATURDAY NIGHT AS OUR NEXT SYSTEM BEGINS TO APPROACH. NAM 850MB
SURFACE INDICATES STRONG WARM AIR ADVECTION AND FORECAST
SOUNDINGS SHOW MID AND HIGHER LEVEL SATURATION BY 12Z. WILL USE A
BLEND ON LOWS FOR SATURDAY NIGHT.

STRONG WARM AIR ADVECTION WILL BE IN PLACE ON SUNDAY AS THE
APPROACHING LOW PRESSURE SYSTEM PUSHES INTO THE GREAT LAKES AND A
SURGE OF 850MB TEMPERATURES NEAR 4C ARRIVE. HOWEVER COLUMN RH
INCREASES ALONG AS FORECAST SOUNDINGS CONTINUE TO SHOW MID AND
HIGH LEVEL SATURATION. THUS A MOSTLY CLOUDY DAY APPEARS IN STORE.
WILL TREND TOWARD THE COOLER MAVMOS HIGHS HERE GIVEN THE EXPECTED
CLOUD COVER.

THE QUICK MOVING UPPER SUPPORT SWINGS THROUGH INDIANA ON SUNDAY
NIGHT AND THIS FORCING WILL BE OUR BEST CHANCES FOR RAINFALL.
FORECAST SOUNDINGS INDICATE DEEP SATURATION AT THAT TIME AND BEST
CHANCES SHOULD REMAIN ACROSS THE NORTHERN PARTS OF THE FORECAST
AREA WHERE DYNAMICS AND MOISTURE APPEAR MOST FAVORABLE. WILL TREND
POPS HIGHER THAN MAVMOS...PARTICULARLY DURING THE EVENING HOURS
ON SUNDAY. GIVEN THE EXPECTED CLOUDS AND RAIN A BLEND ON LOWS
LOOKS REASONABLE.

DRY WEATHER IS EXPECTED TO RETURN ON MONDAY AS THE SHORT WAVE
QUICKLY EXITS THE AREA AND SUBSIDENCE RETURNS IN THE WAKE OF THE
SYSTEM AS ANOTHER RIDGE OF HIGH PRESSURE BUILDS ACROSS THE AREA.
THUS WILL AIM FOR A PARTLY CLOUDY MONDAY WITH HIGH TEMPERATURES
ABOUT 5-7 DEGREES COOLER THAN EXPECTED PERSISTENCE DUE TO COLD AIR
ADVECTION IN THE WAKE OF THE SYSTEM ALONG WITH EXPECTED 850MB
TEMPERATURES NEAR -1C.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...

TIMING OF THE NEXT...STRONGER COLD FRONT WAS FOCUSED ON DURING THE
EXTENDED PERIOD. ALL THE MODEL SUITE HAS PUSH BACK THE TIMING OF
THIS NEXT FRONT. YESTERDAYS MODELS ALL DEPICTED THIS FRONT MOVING
THROUGH ON LATE TUE NIGHT THROUGH WED...BUT NOW THE GFS HAS
PUSHED BACK TIMING TO WED NIGHT INTO THU...WITH THE EURO BEING THE
SLOWEST OF ALL...NOT MOVING THROUGH UNTIL LATE IN THE WORK WEEK.
ALLBLEND GUIDANCE TAKES A BLEND OF THE NEW MODELS PLACING CHANCE POPS
DURING THE DAY ON WED AND LASTING THROUGH THURSDAY. THIS COULD
POSSIBLY BE PUSHED BACK EVEN MORE IF LATER MODEL ISSUANCES
CONTINUE THE SLOWER TRENDS.

THERE WILL BE A BRIEF "WARM UP" THROUGH EARLY NEXT WEEK...AND THEN
TEMPS WILL BEGIN TO COME DOWN ONCE AGAIN AFTER THE FROPA.

&&

.AVIATION /DISCUSSION FOR THE 281800Z TAF ISSUANCE/...

A NARROW RIDGE OF HIGH PRESSURE WILL REMAIN ACROSS CENTRAL
INDIANA AS A LOW PRESSURE SYSTEM (TO OUR SOUTH) TRACKS ACROSS KY
AND VICINITY. A CLIPPER TYPE SYSTEM WILL TRACK TO THE NORTH OF US
TONIGHT...KEEPING ANY PRECIPITATION FROM INVADING THE REGION...SO
FORECAST WILL REMAIN DRY AND IN TERMS OF AVIATION...WILL MAINLY
HAVE TO DEAL WITH MID TO HIGH LEVEL CLOUDS. LOOKS LIKE VFR RIGHT
THROUGH THE PERIOD AS HIGH CLOUDS SHOULD HELP PREVENT MOST FOG
FORMATION.

FROST ADVISORY FROM 2 AM TO 9 AM EDT SATURDAY FOR INZ021-028>031-
