18Z DATA ANALYSIS HAD LOW PRESSURE CENTERED NEAR DETROIT MI AND HIGH

IMAGERY HAD THE SHORTWAVE RESPONSIBLE FOR THE SFC LOW MOVING ACROSS

FCST AREA RATHER QUICKLY AS OF 18-19Z. CLOUDS CLEARING QUICKLY IN
THE WAKE OF THE MID LEVEL TROUGH AXIS...ALREADY INTO THE NORTHWEST
THIRD OF THE FCST AREA AS OF 19Z. TIGHT PRESSURE GRADIENT OVER MUCH

ACROSS THE UPPER MIDWEST IN THE WAKE OF THE LOW...WITH FALLING
DAYTIME TEMPS ACROSS MUCH OF WI/IA AND -5F TO +10F ABOVE ACROSS MUCH
OF MN.

17.12Z MODELS LOOK TO HAVE INITIALIZED WELL AND OFFER VERY SIMILAR
SOLUTIONS FOR TONIGHT THRU THU NIGHT. DIFFERENCES CROP UP WITH THE
LATITUDE OF A PASSING SHORTWAVE/LIFT/SATURATION/PRECIP CENTERED ON

DPROG/DT OF 500MB HGTS AT 17.12Z SHOWED MODEL RUNS OF 15.12Z AND
16.12Z VERIFIED REASONABLY WELL ACROSS NOAM WITH A TREND TOWARD A
COMPROMISE OF THE EARLIER RUNS. FOR TONIGHT/WED MODELS CONVERGING
TOWARD A TIGHTER CONSENSUS SOLUTION...FAVORING STRONGER BUT FASTER
OF EARLIER SOLUTIONS WITH THE NEXT SHORTWAVE TROUGH INTO MN BY 00Z
THU. BETTER CONSENSUS FOR THIS TROUGH TO QUICKLY PASS WED NIGHT AND
BROAD...GENERALLY QUIET WEST/NORTHWEST FLOW FOR THU/THU NIGHT.
TIGHTER CONSENSUS FRI/FRI NIGHT IS SLOWER/STRONGER WITH THE NEXT
WAVE MOVING ACROSS THE CENTRAL PLAINS FRI THEN ACROSS THE MID/UPPER
MS VALLEY FRI NIGHT...BUT STILL SOME STRENGTH/LOW LEVEL FEATURE
DIFFERENCES WITH THIS FEATURE AND ITS IMPACTS ON THE AREA FRI. NO
MODEL WITH CLEARLY BETTER RUN-TO-RUN CONSISTENCY THIS CYCLE. CHECK
OF OBS VS. MODEL DATA AT 18Z SHOWED MODELS LOOKING GOOD WITH THE
CENTRAL CONUS MASS FIELDS. PER WV IMAGERY...ALL MODELS LOOKED QUITE
GOOD WITH THE SHORTWAVE DETAILS OVER NOAM/EASTERN PAC. ALL MODELS
ALSO LOOKED TO DO A GOOD JOB WITH THE 12Z-18Z PRECIP/SNOW ACROSS
THE UPPER MIDWEST. NO CLEAR MODEL FAVORITE THIS CYCLE AND WITH A
TREND TOWARD A COMPROMISE CONSENSUS OF THE EARLIER RUNS...FAVORED
THE MODEL/ENSEMBLE BLEND THIS CYCLE. SHORT TERM FCST CONFIDENCE ON
THE GOOD SIDE THIS CYCLE.

FOR THE SHORT TERM...QUIET/COLD WEATHER TONIGHT WITH THE SFC RIDGE
AXIS IN THE PLAINS QUICKLY TRANSLATING TO OVER WI BY 12Z WED.
WITH WINDS BECOMING LIGHT...2-5 INCHES OF SNOW COVER...MOSTLY CLEAR
SKIES AND THE COLD AIRMASS /925MB TEMPS -12C TO -16C/ OVER THE

PROGRESSION OF SYSTEMS IN NEARLY ZONAL FLOW...925-850MB WARM
ADVECTION ALREADY STARTS TO SPREAD ACROSS THE AREA LATE TONIGHT.
THIS AND INCREASING SOUTH WINDS LATE SHOULD HELP KEEP TEMPS FROM
BOTTOMING WELL BELOW ZERO TONIGHT. RATHER STRONG 925-850MB WARM
ADVECTION AHEAD OF THE NEXT LOW/WEAK SHORTWAVE SPREADS ACROSS THE
AREA WED. BRISK SOUTH WINDS WED TO AID MIXING/WARMING WITH NEAR
NORMAL HIGHS EXPECTED. AIRMASS AHEAD OF THIS FEATURE QUITE DRY AND
WITH THE SOURCE REGION OF THE 925-850MB AIR THE CENTRAL PLAINS...
MUCH OF THE FORCING/LIFT AHEAD OF THIS FEATURE WILL WORK TO SATURATE
THE COLUMN. SFC-MID LEVEL TROUGH AXIS MOVES QUICKLY ACROSS THE AREA
WED EVENING. WHAT SATURATION THAT DOES OCCUR BETWEEN 925-700MB IS
MAINLY OVER THE NORTHEAST HALF OF THE FCST AREA AND LIMITED 20-40
PERCENT -SN CHANCES TO THE NORTHEAST 2/3 OF THE FCST AREA WITH

LATER WED NIGHT AND THU. TIGHTER PRESSURE GRADIENT OVER THE AREA
LATE WED NIGHT/THU MORNING ALONG WITH THE COLD ADVECTION/SUBSIDENCE
AND STEEP SFC-900MB LAPSE RATES SHOULD ALLOW FOR BRISK NORTHWEST
WINDS. THIS ALONG WITH TEMPS FALLING TO NEAR OR BELOW ZERO RESULTS

MOVING ACROSS THE AREA. THE SFC HIGH MOVES OVERHEAD THU NIGHT FOR
ANOTHER COLD NIGHT WITH LIGHTER WINDS. LOWS LIKELY TO BE THU

BEGIN TO INCREASE AHEAD OF THE NEXT SHORTWAVE TROUGH. GOOD MODEL
CONSENSUS FOR SOME DEEPER 850-500MB MOISTURE TO ACCOMPANY THIS
WAVE. MDT/STRONG 925-700MB WARM ADVECTION/ISENTROPIC LIFT WITH SOME
850-700MB FN CONVERGENCE AND 300MB DIVERGENCE IN THE RIGHT ENTRANCE
REGION OF A 110-130KT JET OVER/NORTH OF LK SUPERIOR. RATHER DEEP
LIFT SIGNAL SHOWING UP...WITH INDICATIONS IN SOME MODEL SOUNDINGS
THE -12C TO -18C DENDRITIC GROWTH ZONE COULD BE 200+MB DEEP. GIVEN
THE DEPTH OF THE MOISTURE/LIFT THIS COULD RESULT IN SNOW-WATER
RATIOS IN EASILY IN EXCESS OF 20 TO 1. WITH THE MODEL/ENSEMBLE
CONSENSUS PRODUCING 0.10 TO AS MUCH AS 0.40 INCH OF QPF OVER
MAINLY THE CENTRAL/SOUTH PARTS OF THE FCST AREA CENTERED ON FRI...
A FLUFFY SNOWFALL OF 2 TO AS MUCH AS 8 INCHES LOOKING POSSIBLE ON
FRI. AS THE MODEL CONSENSUS TIGHTENS WITH BETTER POSITION DETAILS...
WINTER WEATHER HEADLINES ARE LOOKING NECESSARY FOR PARTS OF THE FCST
AREA AS EARLY AS LATE THU NIGHT AND POSSIBLY INTO FRI EVENING. FOR
NOW RAISED SNOW CHANCE ON FRI INTO THE 60-70 PERCENT RANGE OVER THE
SOUTHERN 3/4 OF THE FCST AREA. LIKE THE PREVIOUS SYSTEMS...THIS ONE
LOOKS TO EXIT QUICKLY FRI EVENING WITH DECREASING CLOUDS/HIGH
PRESSURE BUILDING IN OVERNIGHT.

FAVORING THE MODEL/ENSEMBLE CONSENSUS...TRENDED LOWS/HIGHS FOR
TONIGHT THRU FRI NIGHT TOWARD A BLEND OF THE NUMERICAL TEMP
GUIDANCE. WITH THE WINDS FOR MIXING LATE WED NIGHT...DID FAVOR
WARMER OF GUIDANCE LOWS. ALSO FAVORED WARMER OF GUIDANCE LOWS THU
NIGHT WITH INCREASING CLOUDS/WARM ADVECTION AFTER MIDNIGHT.

.LONG TERM...SATURDAY THROUGH TUESDAY
313 PM CST TUE JAN 17 2012

17.00Z MEDIUM RANGE MODELS IN REASONABLY GOOD AGREEMENT WITH EACH
OTHER AND THEIR PREVIOUS RUNS SAT...WITH BROAD NEARLY ZONAL FLOW
ACROSS THE CONUS. DIFFERENCES WITH THE TIMING OF WEAKER SHORTWAVES
IN THE ZONAL FLOW...BUT THIS NOT UNEXPECTED AT THE DAY 4 TIME-FRAME.
BETTER CONSISTENCY AMONG MODELS ON SUN FOR A STRONGER SHORTWAVE
TROUGH TO CROSS THE UPPER MIDWEST AND TROUGHING TO BE DIGGING INTO
THE WEST COAST...WITH GEM/ECMWF FASTER THAN GFS/UKMET. RUN-TO-RUN
CONSISTENCY DECREASES ON SUN. CONSISTENCY BETWEEN 17.00Z GFS/ECMWF
DECREASES FOR MON/TUE WITH SPEED/STRENGTH OF THE SUNDAY WEST COAST
TROUGHING AS IT MOVES ACROSS THE ROCKIES THEN INTO THE CENTRAL
CONUS BY TUE. EACH MAINTAINS DECENT CONSISTENCY OF TIMING/STRENGTH
TO ITS 16.00Z...HOWEVER 17.12Z HAS TRENDED TOWARD A MORE PROGRESSIVE
SOLUTION MON/TUE...MORE SIMILAR TO THE MORE RUN-TO-RUN CONSISTENT
GFS. LONG TERM FCST CONFIDENCE AVERAGE TO GOOD SAT/SUN THEN BELOW
AVERAGE MON/TUE. SMALLER SCALE ZONAL FLOW DETAIL DIFFERENCES SAT/SUN
DAYS 4/5 WILL HAVE TO WAIT UNTIL IN THE DAY 1/2 TIME-FRAME TO SETTLE
DOWN...THUS WILL PREFER THE MODEL/ENSEMBLE CONSENSUS FOR NOW THESE
PERIODS. PMDEPD DISCUSSION TRENDS TOWARD FAVORING THE SLOWER ECMWF
SOLUTION MON/TUE...BUT WITH THE TREND OF THE 17.12Z ECMWF TOWARD THE
GFS...WITH FAVOR AN EQUAL WEIGHTED MODEL BLEND FOR MON/TUE AT THIS
POINT. MODEL/ENSEMBLE CONSENSUS WOULD HAVE COLD HIGH PRESSURE
SETTLED OVER THE AREA FOR SAT...THEN THE SHORTWAVE TROUGH WITH A SFC
TROUGH/FRONT TO MOVE ACROSS THE REGION SUN. MODELS DIFFER ON HOW
MUCH 925-850MB WARMING OCCURS IN THE WARM ADVECTION AHEAD OF THE
WAVE...WITH A -RA OR -SN CHANCE CENTERED ON SUN REASONABLE FOR NOW.
THE 925-850MB WARMING CONTINUES INTO MON AS THE STRONG TROUGHING
DIGS THRU THE ROCKIES AND SOUTH/SOUTHWEST FLOW CONTINUES OVER THE
PLAINS INTO THE UPPER MIDWEST. DEPENDING ON WHICH IF ANY MODEL MAY
BE MORE CORRECT...CARRIED A -RA/-SN CHANCE ON MON FOR NOW. STRONG
TROUGHING WOULD MOVE INTO THE MID/UPPER MS VALLEY TUE. MODEL LOW
LEVEL THERMAL PROFILES/850MB TEMPS INDICATE PRECIP TYPE
UNCERTAINTIES TUE AND CONTINUED A -RA/-SN MIX FOR MUCH OF THE AREA
FOR NOW. WITH FCST CONFIDENCE MOSTLY IN THE AVERAGE TO LOW RANGE...
FOR THE MOST PART STAYED NEAR THE MODEL/ENSEMBLE CONSENSUS IN THE
DAY 4-7 PERIOD.

.AVIATION...THROUGH 06Z THURSDAY
1143 PM CST TUE JAN 17 2012

THE MAIN CONCERN IN THE SHORT TERM IS WITH THE WINDS GOING INTO
WEDNESDAY AFTERNOON AS A RIDGE OF HIGH PRESSURE MOVES THROUGH THE
REGION TONIGHT. THIS RIDGE AXIS IS CURRENTLY OVER CENTRAL
MINNESOTA AND IOWA AND WILL BE EAST OF THE MISSISSIPPI RIVER BY
DAY BREAK. THIS WILL BRING WESTERLY WINDS TO OUT OF THE SOUTH FOR
MUCH OF WEDNESDAY. AS A LOW PRESSURE SYSTEM TRACKS THROUGH THE
DAKOTAS TOWARD NORTHERN MINNESOTA...IT WILL DEEPEN AND TIGHTEN UP
THE PRESSURE GRADIENT ACROSS THE TAF REGION. THIS WILL LEAD TO
SOME GUSTS IN THE 25 TO 30KT RANGE OUT OF THE SOUTH THROUGH THE
AFTERNOON. AS THE LOW PASSES THROUGH THE NORTH...A COLD FRONT WILL
COME THROUGH EARLY IN THE EVENING AND BRING WITH IT SOME SNOW
SHOWERS AND A WIND SHIFT TO THE NORTHWEST. CEILINGS WILL LIKELY
ALSO DROP BEHIND THE FRONT TO AT LEAST MVFR AND POSSIBLY HIGH END
IFR.
