AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
703 PM EST WED DEC 26 2012

.UPDATE...

AS OF 630 PM...MOST OF THE SNOWFALL REPORTS HAVE THUS FAR BEEN IN
THE 3 TO 6 INCH RANGE ACROSS THE ADVISORY AREA. OF CONCERN IS THE
SOLID 5 TO 6 INCH REPORTS ALREADY RECEIVED ACROSS EASTERN
OAKLAND...MACOMB AND ST CLAIR COUNTIES. THE MID LEVEL
DEFORMATION...WHILE WEAKENING...SHOULD REMAIN NEARLY STATIONARY
OVER THE EAST-CENTRAL PORTIONS OF THE FORECAST AREA THROUGH 03Z.
SATELLITE/RADAR COMPOSIT ALSO SUGGEST A GOOD FEED OF ATLANTIC
MOISTURE INTO THE EASTERN GREAT LAKES...WHICH IS ALWAYS CONCERNING
IN THESE TYPE OF SYSTEMS. GIVEN THE EXPECTATION FOR ANOTHER 2 TO 3
HOURS OF GOOD LIFT AND CONSIDERING THE REPORTS ALREADY
RECEIVED...THE ADVISORY WILL BE UPGRADED TO A WARNING ACROSS
MACOMB...ST CLAIR AND SANILAC COUNTIES AS SNOW ACCUMULATIONS OF 6
TO 9 INCHES APPEAR POSSIBLE. WHILE CONDITIONS WILL IMPROVE
OVERNIGHT...THERE DOES APPEAR TO BE A BRIEF PERIOD OF IDEAL LAKE
ENHANCEMENT ALONG THE LAKE HURON SHORELINE FROM PORT SANILAC DOWN
TO PORT HURON WHICH COULD CERTAINLY ADD ANOTHER INCH OR TWO ONTO
THE SYSTEM SNOWFALL.

ANOTHER AREA OF CONCERN HAS BEEN THE NEAR STEADY BAND OF ENHANCED
DEFORMATION WHICH SET UP FROM SOUTHERN SHIAWASSEE COUNTY UP
THROUGH CENTRAL GENESEE COUNTY AND INTO NORTHERN LAPEER COUNTY.
THIS WILL PROMPT AN UPGRADE TO AN ADVISORY FOR SHIAWASSEE COUNTY.
WILL HOLD ONTO THE ADVISORY FOR GENESEE AND LAPEER BUT ADJUST
ACCUMS UP SLIGHTLY. ALTHOUGH SNOW HAS BEEN DIMINISHING ACROSS THE
REMAINDER OF THE AREA...CONSIDERABLE BLOWING AND DRIFTING THIS
EVENING WILL SUPPORT HOLDING ONTO THE CURRENT ADVISORIES.

AN UPDATED WSW WILL BE ISSUED BY 730 PM.

&&

.AVIATION...ISSUED 605 PM EST WED DEC 26 2012

//DISCUSSION...

RECENT OBSERVATIONS OVER SE MI ARE SUPPORTING A WEAKENING TREND TO
THE SNOW WHICH HAS BEEN ONGOING FOR SEVERAL HOURS. THE STORM
SYSTEM NOW IMPACTING SE MI SHOULD UNDERGO RAPID WEAKENING DURING
THE COURSE OF THE EVENING...WITH THE HIGHER INTENSITY SNOWFALL
SHIFTING TOWARD THE THUMB REGION BEFORE DIMINISHING OVERNIGHT.
THERE WILL HOWEVER CONTINUE TO BE SPORADIC HIGHER INTENSITY BURSTS
OF SNOW THIS EVENING...PARTICULARLY AROUND PTK AND FNT. NORTH-
NORTHEAST WINDS WILL GUST OVER 20 KNOTS AT TIMES THIS
EVENING...WHICH WILL LEAD TO SOME DRIFTING OF THE SNOW THAT HAS
ALREADY FALLEN. CONDITIONS WILL THEN RAPIDLY IMPROVE LATE TONIGHT
THROUGH THURS MORNING AS WINDS BACK TO THE NORTHWEST AND MUCH
DRIER AIR FUNNELS INTO THE AREA.

FOR DTW...EXPECT THERE WILL BE SOME FLUCTUATIONS IN SNOWFALL
INTENSITY BETWEEN 00Z AND 03Z...WITH THE OVERALL TREND BEING A
WEAKENING ONE. ADDITIONAL ACCUMULATIONS BETWEEN 00Z AND 04Z SHOULD
REMAIN UNDER TWO INCHES. THE GUSTY WINDS TONIGHT WILL LIKELY LEAD TO
SOME BLOWING AND DRIFTING OF THE SNOW WHICH HAS ALREADY FALLEN.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN CEILINGS BELOW 5000 FT TONIGHT AND THURSDAY
MORNING.

* HIGH CONFIDENCE THAT PRECIPITATION WILL FALL AS SNOW WEDNESDAY
  AFTERNOON AND EVENING.

&&

.PREV DISCUSSION...ISSUED 358 PM EST WED DEC 26 2012

SHORT TERM...THROUGH TONIGHT

SNOW WILL CONTINUE TO SPREAD INTO THE AREA TONIGHT AS MOISTURE WRAPS
AROUND A LOW PRESSURE SYSTEM TRACKING FROM THE TENNESSEE VALLEY TO
THE ATLANTIC COAST. LOWER MICHIGAN WILL REMAIN ON THE PERIPHERY OF
THIS SYSTEM...WITH THE STRONGEST FORCING AND GREATEST MOISTURE
REMAINING SOUTHEAST OF HERE. A GENERAL 3 TO 6 INCHES OF ACCUMULATION
REMAINS IN THE FORECAST (THOUGH ACTUAL AMOUNTS WERE INCREASED
SLIGHTLY SOUTH OF I-69 AND OVER THE THUMB). HEADLINE ADJUSTMENTS
WERE ONLY MADE TO SPEED UP ARRIVAL OF SNOW BY A FEW HOURS BETWEEN
M-59 AND I-69.

WATER VAPOR IMAGERY THIS AFTERNOON SHOWS THE UPPER LOW OVER EASTERN
KY HAS BEGUN TO TAKE ON A LITTLE MORE OF A NEGATIVE TILT...WITH
STRONGER AREAS OF VORTICITY STARTING TO SPLIT...WITH ONE CHUNK STILL
IN THE CENTER OF THE LOW AND ANOTHER MAKING A BEE-LINE FOR THE EAST
COAST. THIS HAS ALREADY BEGUN TO INDUCE A SECONDARY AREA OF LOW
PRESSURE OVER THE CAROLINAS...WITH THE ORIGINAL LOW CENTER STILL
NEAR THE KY/WV BORDER. HEIGHT FALLS AND JET DYNAMICS THIS EVENING
WILL BECOME MORE SUPPORTIVE OF THE SECONDARY AREA...AND EXPECT THE
FIRST LOW CENTER TO FILL LATE THIS AFTERNOON AND ESPECIALLY TONIGHT.
LOOKING AT MODEL TOTAL DEFORMATION FIELDS...STRONGEST DEFORMATION
CONTINUES TO BE DISPLACED TO OUR SOUTHEAST OVER OHIO. HERE IN
MICHIGAN...DEFORMATION AND FGEN LOOK THE STRONGEST AT THE 700-500MB
LEVEL THROUGH ABOUT 00Z. AT THIS TIME...THE LOW SHOULD BE FILLING IN
AND OVERALL FORCING WITHIN THE TROWAL SHOULD WEAKEN. THIS CONTINUES
TO SUPPORT THE IDEA OF AN ADVISORY VERSUS A WARNING...ALTHOUGH
PRECIPITATION WRAPPING AROUND THE BACKSIDE OF THE LOW (NOW OVER
WESTERN MICHIGAN) STILL NEED TO PIVOT AND MOVE OVER THE AREA. THIS
WILL HAVE TO BE WATCHED THROUGHOUT THE EVENING TO SEE IF WEAKENING
TRENDS ARE ACTUALLY OBSERVED. MOISTURE WRAPPING AROUND THE SYSTEM
WILL BRING PW VALUES UP TO ABOUT 0.5 INCHES...WHILE SPECIFIC
HUMIDITIES VALUES RISE TO AROUND 2 G/KG ACROSS THE SOUTHERN AND
EASTERN PORTIONS OF THE FORECAST. DRY SLOT HAS BEEN VERY APPARENT ON
WATER VAPOR THIS AFTERNOON AS IT SURGED UP INTO THE OHIO VALLEY AND
EVEN SOUTHEAST MICHIGAN. MODEL QPF HAS BEEN QUITE A BIT UNDERDONE
WHEN COMPARED TO UPSTREAM OBSERVATIONS OVER
ILLINOIS/INDIANA/OHIO...AND WILL CONTINUE TO UNDERCUT QPF AMOUNTS
FOR AREAS NOT ADJACENT TO LAKE HURON. LIFT WILL ALSO BECOME
DISPLACED FROM WITHIN THE DENDRITIC GROWTH ZONE BY THIS EVENING AS
TROWAL BRINGS IN WARMER TEMPS ALOFT...SO BIG FLAKES NOW BEING
OBSERVED HERE AT NWS DTX WILL BECOME SMALLER...HELPING TO LOWER
ACCUMULATION RATES.

PEAK OF THIS SNOW EVENT STILL LOOKS TO RUN BETWEEN NOW AND ABOUT
03Z/10PM. GUSTY NORTHEAST WINDS WILL ALSO PERSIST INTO
TONIGHT...CREATING AREAS OF BLOWING AND DRIFTING SNOW...AND REDUCING
VISIBILITIES DOWN TO A HALF MILE OR LESS IN THE HEAVIER BURSTS AND
GUSTS.

OVERNIGHT...MEAN WINDS (1000-850MB) FROM THE NORTHEAST WILL ALLOW
FOR SOME LAKE ENHANCEMENT OFF LAKE HURON. GFS/NAM FORECAST SOUNDINGS
FROM OVER THE WATER DO SHOW LAKE TO 850MB TEMPERATURE DIFFERENTIALS
HOVERING AROUND 13 DEG C...BUT WITH EQUILIBRIUM LEVELS ONLY RISING
UP TO BETWEEN 5000-6000 FT. LOCAL GUIDANCE WOULD SUGGEST THIS SHOULD
ADD ANOTHER 2 INCHES TO SYNOPTIC SNOWFALL...RESULTING IN HIGHER
TOTALS ACROSS ST CLAIR AND SANILAC COUNTIES. THIS MAY RUN AROUND 6
TO 7 INCHES NEAR THE LAKESHORE BY THE TIME SNOW TAPERS OFF LATE
TOMORROW MORNING...BUT GIVEN LONG DURATION...THE SNOWFALL STILL
FALLS SHY OF WARNING CRITERIA.

LONG TERM...

LAKE EFFECT SNOW IN THE THUMB WILL DIMINISH STEADILY DURING THURSDAY
MORNING. THE DOWNWARD TREND WILL BE DUE MAINLY TO THE LOSS OF
SYNOPTIC SUPPORT ON THE HEELS OF TODAY'S SYSTEM RESULTING IN A
BACKING TREND IN WIND DIRECTION TOWARD THE NORTHWEST. UNTIL THEN,
INSTABILITY WILL BE OK WITH LAKE TO 850 MB DELTA-T OF 13-15C OVER
EQUILIBRIUM LEVEL AROUND 5000 FEET WHICH WILL BE GOOD ENOUGH FOR
ADDITIONAL ACCUMULATION AROUND AN INCH DURING THE MORNING BEFORE THE
WIND SHIFTS OFFSHORE. SURFACE HIGH PRESSURE WILL THEN SETTLE IN
DURING THE AFTERNOON INTO THURSDAY EVENING HELPING TO PRODUCE A
SHORT PERIOD OF PARTLY CLOUDY CONDITIONS. THE UPPER AIR WAVELENGTH
BETWEEN LOW PRESSURE SYSTEMS OVER THE U.S. IS SHORT SO AN EXCHANGE
OF LOW CLOUDS FOR HIGH WILL BE MARKED BY A SHORT PERIOD OF OPEN SKY
DURING THURSDAY EVENING, LONG ENOUGH TO HELP TEMPERATURES DROP OVER
THE FRESH SNOW COVER. MIN TEMPS IN THE TEENS WILL BE WIDESPREAD OVER
THE REGION.

THE NEXT SYSTEM TO AFFECT THE GREAT LAKES LATER FRIDAY IS ALREADY
MOVING THROUGH THE ROCKIES TODAY. WATER VAPOR SATELLITE IMAGERY
INDICATES THE UPPER WAVE IS ON THE STRONG SIDE NOW BUT THE 12Z
MODELS ARE CONSISTENT WITH PREVIOUS SOLUTIONS THAT SHOW THE WAVE
TAKING ON A WEAK/POSITIVE TILT BY THE TIME IT REACHES THE GREAT
LAKES. THIS APPEARS TO BE DUE TO THE 140 KNOT UPPER LEVEL AXIS
REMAINING ON THE DOWNSTREAM SIDE OF THE LONG WAVE TROUGH WITH ONLY
ABOUT 60 KNOTS DIGGING IN FROM UPSTREAM. OTHERWISE, CONDITIONS FOR
SURFACE CYCLOGENESIS ARE FAVORABLE ENOUGH OVER THE SOUTHERN PLAINS.
MOISTURE AND BAROCLINICITY WILL NOT BE AS GREAT AS WITH TODAY'S
SYSTEM BUT MODEL DEPICTIONS OF THETA-E CROSS SECTIONS INDICATE LOW
LEVEL STABILITY WILL BE ON THE LOW SIDE. THIS IS WORTHY OF NOTING
THE POTENTIAL FOR THE MODELS TO IMPROVE THE ORGANIZATION OF THE
SYSTEM IN UPCOMING FORECAST CYCLES. FOR NOW, POPS FOR FRIDAY INTO
SATURDAY ARE NUDGED HIGHER IN THE CHANCE CATEGORY FOR ANOTHER ROUND
OF SNOW TO START THE WEEKEND. ALL THINGS REMAINING THE SAME NOW TO
THEN AND WE COULD END UP WITH A FRESH INCH OR TWO BEFORE HIGH
PRESSURE BUILDS BACK INTO THE REGION BY SUNDAY.

THE MOST RECENT GLOBAL MODEL SOLUTIONS COLLECTIVELY OFFER A
PSEUDO-REX BLOCK CONFIGURATION IN THE UPPER AIR PATTERN TO START
NEXT WEEK. THIS WOULD SUPPORT COLD NORTHWEST FLOW ALOFT PERSISTING
OVER THE GREAT LAKES FOR THE FIRST HALF OF THE WEEK. OTHER THAN A
POSSIBLE BACK DOOR COLD FRONT AROUND MONDAY NIGHT, THIS MEANS DRY
CONDITIONS AND TEMPERATURES TYPICAL FOR EARLY JANUARY IN SE
MICHIGAN.

MARINE...

SNOW AND STRONG NORTHEAST WIND WILL CONTINUE THROUGH TONIGHT AS A
WINTER LOW PRESSURE SYSTEM MOVES FROM EASTERN KENTUCKY TO THE MID
ATLANTIC COAST. GALE WARNINGS REMAIN IN EFFECT FOR SAGINAW BAY AND
WESTERN LAKE ERIE WHERE THE WIND DIRECTION AND ASSOCIATED
CHANNELING/FUNNELING WILL HELP WITH FREQUENT GALE FORCE GUSTS. THE
WIND CONDITIONS WILL EASE CONSIDERABLY THURSDAY BUT HIGH WAVES WILL
PERSIST OVER THE SOUTH HALF OF LAKE HURON THROUGH THURSDAY NIGHT
REQUIRING SMALL CRAFT ADVISORIES DURING THAT TIME. AFTER A WEAK
ROUND OF HIGH PRESSURE, THE NEXT LOW PRESSURE SYSTEM WILL ARRIVE
LATE FRIDAY BUT THIS SYSTEM IS NOT EXPECTED TO BE AS STRONG. MARINE
CONDITIONS ARE THEN LIKELY TO BE MOSTLY FAVORABLE THROUGH THE
WEEKEND.
