AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
326 AM EST FRI JAN 20 2012

.UPDATE...
THE AVIATION SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...COLD ARCTIC AIR WAS IN PLACE ACROSS CENTRAL INDIANA
EARLY THIS MORNING AS A HIGH PRESSURE SYSTEM WILL QUICKLY PUSH
THROUGH THE GREAT LAKES TODAY. LOW PRESSURE IS EXPECTED TO PUSH
OUT OF THE THE SOUTHERN PLAINS AND PUSH INTO THE TENNESSEE RIVER
VALLEY TONIGHT. WITH THE COLD AIR IN PLACE...THE LOW WILL BRING
SNOW TO THE NORTHERN PARTS OF CENTRAL INDIANA...AND FREEZING RAIN
WILL BE POSSIBLE ACROSS THE CENTRAL PARTS OF THE STATE.

THE LOW WILL DEPART ON SATURDAY...BRINGING PRECIPITATION TO AN END
AND ALLOWING ANOTHER QUICK MOVING AREA OF HIGH PRESSURE TO PUSH
INTO THE REGION...PROVIDING ANOTHER COLD WINTER DAY AND NIGHT.

ANOTHER STRONG LOW PRESSURE IS EXPECTED TO DEVELOP IN THE CENTRAL
PLAINS ON SUNDAY. THIS WILL ALLOW MUCH WARMER AND MOIST GULF AIR
TO ARRIVE IN THE OHIO VALLEY. THIS LOW PRESSURE SYSTEM IS THEN
EXPECTED TO PUSH ACROSS THE AREA ON SUNDAY NIGHT INTO
MONDAY...BRINGING CHANCES FOR MORE RAIN AND PERHAPS A
THUNDERSTORM.

FINALLY...YET ANOTHER STORM SYSTEM WILL BRING RAIN CHANCES
STARTING WEDNESDAY AND POSSIBLY MIXING WITH SNOW ACROSS NORTHERN
SECTIONS OF CENTRAL INDIANA WEDNESDAY NIGHT.

&&

.NEAR TERM /TODAY AND TONIGHT/...

MAIN FORECAST CHALLENGE TODAY WILL BE PRECIPITATION TYPE. VERY
COLD HIGH PRESSURE WAS IN PLACE ACROSS CENTRAL INDIANA AND HIGH
PRESSURE OVER THE UPPER MIDWEST WAS BUILDING INTO THE OHIO VALLEY.
SKIES WERE CLEARING AND THE FRESH SNOW ACROSS THE NORTHERN PARTS
OF THE FORECAST AREA WAS ALLOW TEMPS TO PLUMMET.

THE HIGH IS EXPECTED TO QUICKLY MOVE ACROSS THE STATE TODAY AS
TIME HEIGHTS AND FORECAST SOUNDINGS INDICATE A DRY COLUMN. WATER
VAPOR IMAGERY SHOWS A STRONG SHORT WAVE OVER THE ROCKIES WITH
PLENTY OF MOISTURE STREAMING EAST IN THE QUICK ZONAL FLOW ALOFT.
EXPECT CLOUDS TO INCREASE RAPIDLY THIS AFTERNOON AS THESE FEATURES
ARRIVE IN THE AREA. AS THE 850 TROUGH DIGS OVER THE CENTRAL PLAINS
THIS AFTERNOON...STRONG WARM AIR ADVECTION WILL BE IN PLACE AS
850MB TEMPS RISE TO NEAR 0C ACROSS THE FORECAST AREA. THE GFS IS A
BIT COOLER THAN NAM AND I PREFER THIS SOLUTION DUE TO THE COLD AIR
IN PLACE AT THE SURFACE ACROSS THE AREA DUE TO THE PREVIOUSLY
DISCUSSED FRESH SNOW. WITH CLOUDS ADVANCING IN THIS MORNING...COLD
AIR MAY BE TRAPPED AT THE SURFACE ALLOWING FOR AN IDEAL FREEZING
RAIN SET-UP.

TOP DOWN METHODOLOGY OF ON THE GFS FORECAST SOUNDINGS REVEALS
MAINLY SNOW ACROSS THE NORTHERN PARTS OF THE FORECAST AREA AND A
LARGE ENOUGH WARM LAYER TO SUPPORT FREEZING RAIN ACROSS THE
CENTRAL AND SOUTH. PRECIPITATABLE WATER IN THE FORECAST SOUNDINGS
INDICATE THAT ANY SNOW AMOUNTS WILL BE CLOSE TO ADVISORY
CRITERIA...THUS WILL AIM FOR A SNOW ADVISORY ACROSS THE NORTH
LATER STARTING THIS AFTERNOON...AND CONTINUING INTO THE OVER NIGHT
HOURS. WILL USE FREEZING RAIN ADVISORY ACROSS THE SOUTHERN PARTS
OF CENTRAL INDIANA...HOWEVER AS THE AIR MASS COOLS FZRA MAY CHANGE
OVER TO MIXED PRECIPITATION OR JUST SNOW ALONG AND NEAR THE I-70
CORRIDOR DURING THE EVENING HOURS.

AS FOR TEMPS WILL TREND COLDER THAN MAVMOS FOR HIGHS AS MAVMOS IS
ALREADY UNDERESTIMATING THE COLD AIR IN PLACE. WILL USE A BLEND ON
LOWS. HIGH CONFIDENCE IN A MEASUREABLE PRECIPITATION EVENT...THUS
WILL TREND POPS HIGHER THAN MAVMOS.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...

FORECAST SOUNDINGS ON SATURDAY DRY OUT QUICKLY AS THE QUICK MOVING
SYSTEM DEPARTS DURING THE MORNING HOURS. ANOTHER QUICK MOVING AREA
OF HIGH PRESSURE THEN WILL SETTLE ACROSS THE THE GREAT LAKES ON
SATURDAY AND SATURDAY NIGHT. AS WEAK RIDGING BUILDS ALOFT...EXPECT
A MOSTLY SUNNY SATURDAY. CLOUDS SHOULD RETURN ON LATE SATURDAY
NIGHT AS RETURN FLOW BEGINS AMID WARM AIR ADVECTION. FORECAST
SOUNDINGS SHOW SATURATED LOWER LEVELS ON LATE SATURDAY NIGHT
AND SUNDAY AS 850MB TEMPERATURES RISE TO NEAR 6C BY 12Z SUNDAY.
WITH SOME NEW SNOW ON THE GROUND...WILL TREND HIGHS AT OR BELOW
MAVMOS FOR SATURDAY HIGHS. GIVEN THE WARM AIR ADVECTION WILL TREND
LOWS ON SATURDAY NIGHT WARMER THAN MAVMOS ALSO.

GFS AND NAM SUGGEST A SHARP TROUGH DIGGING IN THE PLAINS STATES ON
SUNDAY. THIS SYSTEM PUSHES ACROSS CENTRAL INDIANA ON SUNDAY NIGHT
IN A NEGATIVELY TILTED FASHION...WITH PLENTY OF UPPER SUPPORT.
THUS WILL TREND TOWARD CLOUDY SKIES ALONG WITH HIGHS ON SUNDAY
ABOVE MAVMOS AS VERY WARM AIR...NEAR 10C AT 850MB...IS EXPECTED TO
BE ADVECTED ACROSS CENTRAL INDIANA ON STRONG SOUTHERLY WINDS.

AS THE STRONG DYNAMICS PUSH ACROSS THE REGION ALONG WITH THE COLD
FRONT ON SUNDAY NIGHT...WILL INCLUDE THUNDER MENTION AS WELL AS
FORECAST SOUNDINGS INDICATE FAVORABLE LAPSE RATES.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
ENSEMBLES ARE KEYING IN ON TWO SYSTEMS THAT ARE EXPECTED TO AFFECT
THE LOCAL AREA IN THE EXTENDED. THE FIRST ONE WILL BE IN THE PROCESS
OF PASSING OFF TO THE EAST BY MONDAY. WILL KEEP SOME CHANCE POPS FOR
MIXED PRECIPITATION ON MONDAY TO COVER POTENTIAL WRAP AROUND TO THE
REAR OF THE EXITING SYSTEM. NEXT SYSTEM IS EXPECTED ARRIVE TOWARDS
THE MIDDLE OF NEXT WEEK. AT THIS TIME...MAJORITY OF ENSEMBLES ARE
INDICATING RAIN WITH THIS FEATURE...WITH ONLY A FEW SUGGESTING SNOW.
FOR NOW...WILL STICK WITH CHANCE POPS FOR RAIN FOR NEXT WEDNESDAY
AND THURSDAY.

&&

.AVIATION /DISCUSSION FOR THE 200900Z KIND TAF UPDATE/...

NO SIGNIFICANT CHANGES MADE TO THE FORECAST AT THIS TIME. PREVIOUS
DISCUSSION FOLLOWS.

VFR CONDITIONS THROUGH FRIDAY AFTERNOON WITH DETERIORATING
CONDITIONS THEREAFTER AS PRECIP ARRIVES.

MAINLY CLEAR SKIES EARLY THIS MORNING WILL BE BRIEF AS MID LEVEL
CLOUDS EXPAND BACK INTO CENTRAL INDIANA AROUND DAYBREAK AS
OVERRUNNING MOISTURE DEVELOPS ON BACK SIDE OF ARCTIC HIGH PRESSURE
AND AHEAD OF AN APPROACHING WARM FRONT. MODEL SOUNDINGS SHOWING THAT
DRY SUBSIDENT AIR WITHIN THE BOUNDARY LAYER WILL TAKE ITS TIME BEING
SATURATED AS PREDOMINANT EASTERLY FLOW PERSISTS INTO THE AFTERNOON.
ANTICIPATE ONLY A SLOW DROP IN CEILINGS TO BETWEEN 5-10KFT THROUGH
THE MORNING HOURS. THE DRIER AIR WITHIN THE BOUNDARY LAYER WILL BE
SQUEEZED FROM THE OVERRUNNING MOISTURE SPREADING EAST INTO NORTHERN
INDIANA AND DEEPER MOISTURE COURTESY OF ISENTROPIC LIFT EXPANDING
NORTHEAST OUT OF THE LOWER MISSISSIPPI VALLEY. HAVE INTRODUCED VCSH
AND MVFR CONDITIONS AT ALL TERMINALS BETWEEN 18 AND 22Z FROM NORTH
TO SOUTH AS LOWER LEVELS MOISTEN UP.

PRECIP TYPE WILL BE QUESTIONABLE AS WARM ADVECTION WITHIN THE
BOUNDARY LAYER WILL ENABLE TEMPS ABOVE FREEZING ALOFT WITH SURFACE
TEMPS REMAINING BELOW FREEZING. MORE ROBUST PRECIP COVERAGE
ANTICIPATED BY THE EVENING AS A SURFACE WAVE DEVELOPS ALONG THE
FRONT ACROSS THE LOWER OHIO VALLEY. CONFIDENCE GROWING IN PRECIP TO
FALL MAINLY IN THE FORM OF FREEZING RAIN WITH POSSIBLY SOME SLEET
MIXED IN FROM TIME TO TIME AT KBMG...KHUF AND KIND FOR THE DURATION
OF THE EVENING. WITH COLDER AIR ENTRENCHED AT KLAF...PRECIP TYPE
LIKELY TO VARY BETWEEN MAINLY SNOW AND SLEET. ANTICIPATE WIDESPREAD
IFR CONDITIONS TO DEVELOP AFTER SUNSET AND CONTINUE THROUGH THE
REMAINDER OF THE FORECAST PERIOD. AS THE WAVE PASSES BY TO THE
SOUTH...WIND DIRECTION WILL BACK FROM EASTERLY TO N/NE BY 06Z
SATURDAY AND INCREASE TO 10-15KTS. EXPECT PRECIP TO WRAP UP BETWEEN
06-09Z AS BETTER FORCING DIMINISHES WITH THE LOW PULLING AWAY TO THE
EAST.
