Winter Storm in Michigan, December 9 to 10, 2008

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
926 PM EST MON DEC 8 2008

.UPDATE...

NO MAJOR UPDATES PLANNED THIS EVENING. STRENGTHENING AREA OF WARM
AIR ADVECTION/MOIST ISENTROPIC ACCENT CONTINUING TO GENERATE
POCKETS OF LIGHT TO OCCASIONALLY MODERATE PRECIPITATION ACROSS THE
AREA. INITIAL BURST OF LGT-MDT SNOW NOW SHIFTING NORTH OF M-59. TO
THE SOUTH...SEEING MORE OF A TRANSITION TOWARD A VERY LGT MIX
NORTH OF THE WARM FRONT NOW MOVING INTO NORTHERN IN/OH...WITH
PRECIPITATION INTENSITY/SATURATION INSUFFICIENT TO MAINTAIN ALL
SNOW. THIS LIGHT MIX WILL EXPAND NORTHWARD INTO AT LEAST THE I-69
CORRIDOR OVERNIGHT...WITH POCKETS OF LIGHT FREEZING RAIN/DRIZZLE
CREATING A FEW SLICK SPOTS ESPECIALLY ON UNTREATED ROADWAYS/
ELEVATED SURFACES. UPSTREAM TRENDS SUPPORT LATEST MODEL GUIDANCE
IN SHOWING A DRY SLOT WORKING IN FROM SOUTH TO NORTH
OVERNIGHT.

THE EXCEPTION TO ALL THIS WILL BE ACROSS THE TRI-CITIES/NORTHERN
THUMB...WHERE A MORE PROLONGED PERIOD OF PRECIPITATION WILL FOCUS
WITHIN AN AXIS OF DEEPER MOISTURE ADVECTION/STRONGER OVERRUNNING
ALONG THE 850-700MB FRONTAL ZONE. LATEST SOUNDINGS INDICATE
THERMAL/MOISTURE FIELDS WILL SUPPORT ALL SNOW ACROSS THIS
AREA...WITH ACCUMULATIONS OF 2-4 INCHES STILL LOOKING ATTAINABLE
TONIGHT (ESPECIALLY MIDLAND/BAY COUNTIES).

.PREV DISCUSSION...ISSUED 707 PM EST MON DEC 8 2008

AVIATION...

MAIN AREA OF LIGHT SNOW FOCUSED NORTH OF A WARM FRONT WILL SHIFT
NORTHEAST OF DETROIT AND FLINT BY 02Z.  THIS WILL LEAVE CONDITIONS
PRIMARILY WITHIN VFR FOR MUCH OF THE OVERNIGHT PERIOD AT THESE
TERMINALS AS A DRY SLOT WORKS IN.  MBS REMAINS IN BETTER POSITION TO
PICK UP ADDITIONAL POCKETS OF MVFR/BRIEF IFR LIGHT SNOW OVERNIGHT.
CONDITIONS WILL DETERIORATE FROM NORTH TO SOUTH THROUGH THE MORNING
HOURS AS DEEPER MOISTURE AND STRONGER FORCING ACCOMPANY THE APPROACH
OF A LOW PRESSURE SYSTEM. LATEST MODEL SOUNDINGS/TEMPERATURE
PROFILES REMAIN CONSISTENT IN DRIVING WARMER AIR IN AHEAD OF THIS
SYSTEM. THIS WILL KEEP PRECIPITATION ON TUESDAY AS JUST COLD RAIN
AT DETROIT...A RAIN/SNOW MIX TRANSITIONING TO RAIN AT FLINT AND
ALL SNOW AT MBS THROUGH THE AFTERNOON. CONDITIONS WILL LOWER INTO
A PREDOMINANT IFR CONDITION AT ALL TERMINALS DURING THIS TIME...
WITH A PERIOD OF LIFR IN HEAVIER SNOW AT MBS.

PREV DISCUSSION...ISSUED 422 PM EST MON DEC 8 2008

SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT

A WINTER STORM WARNING HAS BEEN ISSUED FOR THE SAGINAW VALLEY AND
PORTIONS OF THE THUMB WHILE A WINTER STORM WATCH REMAINS IN EFFECT
FOR THE I-69 CORRIDOR.

A COMPLEX STORM SYSTEM BRINGING SNOW TO THE NORTH...MIXED
PRECIPITATION TO OUR CENTRAL COUNTIES AND PRIMARILY RAIN TO DETROIT
WILL IMPACT SOUTHEAST MICHIGAN THROUGH TUESDAY EVENING. SHORTWAVE
ENERGY OVER NEW MEXICO WILL ADVANCE TOWARDS THE CENTRAL GREAT LAKES
OVERNIGHT...BRINGING THE ASSOCIATED SURFACE LOW PRESSURE SYSTEM
TAKING SHAPE OVER THE SOUTHERN PLAINS WITH IT. THE SURFACE LOW
BECOMES ELONGATED AND BEGINS TO FILL AS IT MOVES OVER SOUTHEAST
MICHIGAN ON TUESDAY...AS THE UPPER SHORTWAVE GETS ABSORBED INTO THE
LARGER TROUGH SETTING UP OVER THE PLAINS. ADDITIONAL ENERGY WILL
APPROACH FROM NORTHERN ALBERTA...PUSHING A COLD FRONT THROUGH AND
QUICKLY ACCELERATING THE LOW PRESSURE SYSTEM TOWARDS THE EASTERN
GREAT LAKES TUESDAY NIGHT. UNTIL THEN...A PROLONGED PERIOD OF
PRECIPITATION IS EXPECTED OVER THE REGION WITH GOOD MOISTURE
TRANSPORT AHEAD OF THE SURFACE LOW...AND STRONG FRONTOGENESIS AND
DEFORMATION IN PLACE ON THE NORTHWEST SIDE.

A WARM FRONT IS APPROACHING THE REGION LATE THIS AFTERNOON WITH
PRECIPITATION FILLING IN ALONG THE INITIAL 925-850MB FRONT.
PRECIPITATION HAS BEEN VERY LIGHT SO FAR UPSTREAM AND WILL EXPECT TO
SEE MIXED PRECIPITATION REPORTS CHANGE OVER TO SNOW AS EVAPORATIONAL
COOLING HAS AN EFFECT ON THE ATMOSPHERE. TEMPERATURES IN SOUTHEAST
MICHIGAN ARE IN THE UPPER 20S TO NEAR 30 ALONG THE SOUTHERN BORDER
AND WILL GRADUALLY WARM OVERNIGHT(ASIDE FROM BRIEF COOLING AT THE
ONSET OF PRECIPITATION). A SHARP GRADIENT IN TEMPERATURES CAN BE
SEEN ACROSS INDIANA WITH TEMPERATURES IN THE CENTRAL PART OF THE
STATE IN THE MID 30S WHILE THE SOUTH HAS ALREADY RISEN INTO THE 50S.
THIS IS A GOOD SIGN THAT THE WARM AIR WILL IN FACT MAKE IT TO
SOUTHEAST MICHIGAN AS THE SYSTEM APPROACHES OVERNIGHT INTO
TUESDAY...REDUCING THE ICING POTENTIAL ACROSS THE METRO AREA AND
LOCATIONS SOUTH.

THIS INITIAL BAND OF SNOW WILL INCREASE IN INTENSITY AS IT LIFTS
NORTH ACROSS THE AREA TONIGHT...STALLING ACROSS THE SAGINAW VALLEY
AS THE FRONT CONTRACTS. MODEL QPF VARIES FROM .35 TO .5 ACROSS THE
FAR NORTHERN COUNTIES TONIGHT BEFORE THE BAND OF HEAVIEST SNOW LIFTS
JUST NORTH OF THE AREA. A BREAK IS EXPECTED IN THE PRECIPITATION
BEHIND THIS INITIAL BAND AFTER ABOUT 4 AM BUT ACCUMULATIONS COULD BE
HIGHER IF THIS BAND STALLS OVER MIDLAND/BAY COUNTIES.

PRECIPITATION WILL SPREAD NORTHEAST BACK INTO THE AREA LATE TONIGHT
INTO TUESDAY MORNING. THE NAM/GFS ARE GENERALLY LIFTING THE 0C
ISOTHERM UP TO A LANSING TO LEXINGTON LINE ON TUESDAY WITH THERMAL
PROFILES SUPPORTING A MIX ALONG I-69 SOUTH TO AROUND PONTIAC...WITH
PRIMARILY RAIN TOWARDS METRO DETROIT. A BRIEF PERIOD OF FREEZING
RAIN IS POSSIBLE FOR NORTHERN PORTIONS OF METRO DETROIT BUT SHOULD
QUICKLY TRANSITION TO RAIN AS TEMPERATURES WARM INTO THE MID 30S.

CONFIDENCE HAS INCREASED IN POTENTIAL FOR HEAVY SNOW ACROSS THE
SAGINAW VALLEY...DESPITE A BREAK BETWEEN THE FIRST ROUND
TONIGHT...AND THE MORE PERSISTENT AND HEAVY SNOW TUESDAY AFTERNOON.
THE HIGHER RESOLUTION OF THE NAM DOES FOCUS A HEAVIER BAND OF
PRECIPITATION ACROSS MIDLAND/BAY COUNTIES WHICH COULD YIELD SNOWFALL
TOTALS OVER A FOOT. THIS IS REASONABLE BUT WILL WAIT TO SEE THIS
MESOSCALE FEATURE SHOWING UP BEFORE RAISING ACCUMULATIONS. MODELS
ARE ALSO IN FAIRLY GOOD AGREEMENT SHOWING A MID LEVEL DRYSLOT ALSO
WORKING INTO THIS SYSTEM...GENERALLY FROM I-69 SOUTH. GIVEN THE
CURRENT TRACK...THIS SHOULD NOT REDUCE ACCUMULATIONS IN THE WARNING
AREA...BUT MAY CUT BACK ON QPF IN THE I-69 CORRIDOR. THE UNCERTAINTY
REGARDING THE PRECIPITATION TYPE...REDUCED SNOW RATIOS WITH WARMER
TEMPERATURES...AND SURFACE TEMPERATURES HOVERING AROUND FREEZING
WARRANTS LEAVING THE WATCH IN EFFECT OVERNIGHT. IF TEMPERATURES DO
NOT MAKE IT TO 32 THEN ICING WILL BE MORE OF A CONCERN IN THIS
REGION.

LONG TERM...WEDNESDAY THROUGH MONDAY

THE MID TO END OF THE WORK WEEK WILL CONTINUE TO FEATURE PREVAILING
COLD NORTHWEST UPPER LEVEL FLOW...AS THE MAIN JET STREAM RESIDES
ACROSS THE GREAT LAKES REGION. A SERIES OF DISTURBANCES/LOW
PRESSURES WILL TRACK WITHIN THIS FAST FLOW...BUT SHOULD TRACK MOSTLY
NORTH (OVER THE NORTHERN GREAT LAKES)...PROVIDING JUST CHANCE POPS
(MAINLY DURING THURSDAY) EXTENDING THIS FAR SOUTH. CRASHING
INVERSION HEIGHTS AND GENERAL SUBSIDENCE ON WEDNESDAY WILL LEAD TO
FLURRIES AT WORST. MAX TEMPS IN THE 20S LOOK GOOD WITH THE THERMAL
TROUGH WORKING THROUGH (925 MB TEMPS AROUND -10 C). A RIDGE OF HIGH
PRESSURE CRESTING OVER THE CWA EARLY WEDNESDAY EVENING SHOULD ALLOW
FOR A QUICK DROP IN TEMPERATURES BEFORE CLOUDS THICKEN UP AND FILTER
BACK INTO THE AREA. AT THIS POINT...WILL CARRYING SINGLE NUMBERS
OVER THE THUMB REGION...WITH LOWER TEENS ELSEWHERE.

A GRADUAL WARMUP SHOULD THEN COMMENCE ON FRIDAY...AS MEDIUM RANGE
MODELS 12Z EUROPEAN/GFS ARE IN GOOD AGREEMENT FORECASTING A BIG
PATTERN SHIFT...AS LONGWAVE TROUGH SETS UP SHOP OVER THE WEST COAST
DURING THE WEEKEND/EARLY NEXT WEEK...WITH A RIDGE ALONG THE EAST
COAST. UNFORTUNATELY...LOWER MICHIGAN WILL BE CAUGHT IN THE BATTLE
GROUND/BAROCLINIC ZONE WITH THE INCREASING SOUTHWEST FLOW
ALLOWING FOR A STORM TRACK THROUGH THE GREAT LAKES REGION. AT THIS
POINT...IT APPEARS SOUTHEAST MICHIGAN WILL BE ON THE WARM SIDE OF
THE LOW(S)...BUT WILL CARRY A CHANCE OF SNOW AND RAIN
(SUNDAY-MONDAY) DUE TO THE INHERENT UNCERTAINTY THAT FAR OUT.

MARINE...

SOUTHERLY WINDS WILL CONTINUE TO INCREASE A BIT MORE THIS
EVENING...OUT AHEAD OF AN APPROACHING LOW PRESSURE SYSTEM. THIS LOW
WILL MOVE THROUGH THE SOUTHERN GREAT LAKES TOMORROW...WITH STRONG
NORTHWEST WINDS OF 20 TO 30 KNOTS EXPECTED BEHIND THE PASSAGE
OF THE LOW ON WEDNESDAY. A RIDGE OF HIGH PRESSURE WILL MOVE IN
WEDNESDAY EVENING...ALLOWING THE WINDS TO QUICKLY DIMINISH.
HOWEVER...SOUTHWEST WINDS WILL BE ON THE INCREASE DURING
THURSDAY...REACHING 20 TO 30 KNOTS...OUT AHEAD OF OUR NEXT LOW
PRESSURE SYSTEM...WHICH WILL TRACK THROUGH THE NORTHERN GREAT LAKES.
