Heavy Snow in Michigan, January 11 to 12, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
848 PM EST TUE JAN 11 2011

.UPDATE...

BROADER LARGE SCALE ASCENT SUPPORTED BY PERSISTENT SYSTEM RELATIVE
ISENTROPIC ASCENT SHOWING SIGNS OF DIMINISHING...WITH FORCING
BECOMING MORE MESOSCALE/BANDED AS THE MID LEVEL DEFORMATION/TROWAL
AXIS CONTRACTS AND PIVOTS OVER SOUTHEAST LOWER MICHIGAN. LATEST
RADAR TRENDS CONFIRM THIS EVOLUTION...WITH A TRANSITION OF THE
HIGHER INTENSITY SNOWFALL INTO A CORRIDOR EXTENDING FROM NORTHERN
WAYNE/EASTERN OAKLAND INTO MCCOMB AND ST CLAIR COUNTIES. LATEST
SPOTTER REPORTS AND RADAR ESTIMATES INDICATE ANYWHERE FROM ONE
HALF TO ONE INCH PER HOUR RATES OVER A PORTION OF THIS AREA. IN
LIGHT OF THESE TRENDS...WILL ADJUST THE HIGH END AMOUNTS UP
ANOTHER INCH ACROSS THIS QUADRANT FOR A SOLID 3-6 INCH SWATH
ENCOMPASSING THE DETROIT METRO AREA.

NO OTHER CHANGES PLANNED ATTM.  WITH THE STRONGER ASCENT STILL
EXPECTED TO RELEASE OVERNIGHT...WILL LIKELY ALLOW THE ADVISORY TO
END AT MIDNIGHT. ADDITIONAL SUPPORT WILL RESIDE WITHIN AN AREA OF
ENHANCED CONVERGENCE EXTENING SOUTH OFF LAKE HURON. HOWEVER...THE
SETUP LOOKS MARGINAL GIVEN A BACKING LOW LEVEL FLOW AND
EQUILIBRIUM HEIGHTS BELOW 6K FT. THEREFORE...WILL CONTINUE TO
CONFINE ADDITIONAL ACCUMULATIONS OF OVER AN INCH TO THE FAR
EASTERN THUMB DURING THE EARLY MORNING PERIOD...LESS THAN AN INCH
ELSEWHERE.

&&

.AVIATION...ISSUED 650 PM EST TUE JAN 11 2011

WIDESPREAD AREA OF MODERATE SNOW FOCUSED WITHIN THE NORTHWEST
QUADRANT OF A PASSING LOW PRESSURE NOW ENCOMPASSING ALL TERMINALS.
PREVAILING IFR CONDITIONS WILL CONTINUE THROUGH THE REMAINDER OF THE
EVENING UNDER PERSISTENT ASCENT WITHIN THE ASSOCIATED DEFORMATION
ZONE.  BRIEF BURSTS OF HEAVIER SNOW WILL CONTINUE TO IMPACT DTW/DET
AND PTK THROUGH MIDNIGHT...LEADING TO INTERMITTENT REDUCTIONS OF
VISIBILITY BELOW 1 MILE AND BRINGING ADDITIONAL SNOWFALL
ACCUMULATIONS OF UP TO 2 INCHES.  SNOWFALL INTENSITY WILL DIMINISH
OVERNIGHT AS THE STRONGER FORCING SHIFTS EAST.  THIS WILL ALLOW
CONDITIONS TO EASE BACK INTO MVFR IN LIGHT SNOW THROUGH THE EARLY
MORNING HOURS.  STRATOCU FIELD WILL LINGER INTO WEDNESDAY SUSTAINED BY
SUFFICIENT MOISTURE DEPTH AND STEEP LOW TO MID LEVEL LAPSE RATES.
LATEST SOUNDINGS SUGGEST CEILINGS WILL HOVER WITHIN THE
2500-4000 FT RANGE...WHILE SUPPORTING A FEW FLURRIES. BACKING LOW
LEVEL WINDS FROM THE NORTHEAST THIS EVENING WILL SETTLE INTO A
PREVAILING NORTHWEST TRAJECTORY ON WEDNESDAY...WITH GUSTS TO 20
KNOTS FROM LATE MORNING ONWARD.

&&

.PREV DISCUSSION...ISSUED 349 PM EST TUE JAN 11 2011

SHORT TERM...THIS AFTERNOON AND TONIGHT

WINTER WEATHER ADVISORY CONTINUES UNTIL MIDNIGHT FOR THE I-69
CORRIDOR SOUTH TO THE OHIO BORDER AS A LOW PRESSURE SYSTEM LIFTING
THROUGH OHIO SPREADS SNOW INTO LOWER MICHIGAN. 00Z MODEL SUITE
CONTINUES TO PLACE LIFT WITHIN THE DEFORMATION ZONE ACROSS SOUTHEAST
MICHIGAN THROUGH THIS EVENING. ANALYSIS OF ISENTROPIC ASCENT (SYSTEM
RELATIVE AT 280K AND 285K) SHOWS GOOD LIFT OCCURRING THROUGH THIS
EVENING. ASCENT LOOKS TO BE CENTERED WITHIN THE DENDRITIC GROWTH
ZONE FROM THE OHIO BORDER UP THROUGH I-69...BEFORE THEN BECOMING
CENTERED HIGHER UP IN THE ATMOSPHERE AS YOU MOVE NORTH TOWARDS THE
TRI-CITIES. MID-LEVEL LAPSE RATES WILL ALSO STEEPEN THIS EVENING AS
THE UPPER LOW SLIDES ACROSS NORTHERN OHIO...AND CONTINUE TO SUPPORT
SOME HEAVIER BURSTS OF SNOW. ADVISORIES LOOK ON TRACK WITH RADAR
DATA...SURFACE OBSERVATIONS...AND SATELLITE CLOUD ICE ENHANCEMENTS
INDICATING THE HEAVIEST SNOWFALL SOUTH OF A LINE FROM FLINT TO
MILWAUKEE. STILL EXPECTING 3 TO 5 INCHES OF STORM TOTAL ACCUMULATION
BY TOMORROW MORNING...WITH SNOW INTENSITY CRITERIA FOR AN ADVISORY
MET THIS AFTERNOON AND EVENING (MORE THAN 2 INCHES IN A 6 HOUR
PERIOD). SNOWFALL RATES WE ARE CURRENTLY SEEING WILL SUSTAIN
THEMSELVES THROUGH THE EVENING RUSH HOUR AND A LITTLE BEYOND.

FURTHER NORTH ACROSS THE TRI-CITIES AND THUMB...WEAKER LIFT AND
LOWER LAPSE RATES WILL NOT SUPPORT THE HIGHER SNOWFALL INTENSITIES
WE WILL SEE FURTHER SOUTH. REGARDLESS...CAN STILL EXPECT 1 TO 2
INCHES OF SNOWFALL TO AFFECT EVENING TRAVEL. SHOULD THEN SEE ANOTHER
1 TO 2 INCHES OF SNOWFALL DURING THE OVERNIGHT HOURS...WITH THE
EXCEPTION OF THE THUMB WHERE LAKE-ENHANCEMENT WILL BRING HIGHER
AMOUNTS. THINK WITH INVERSION HEIGHTS ONLY REACHING 5000-6000
FEET...AND WITH LAPSE RATES FALLING THROUGH THE NIGHT BY THE TIME
THE WINDS TURN MORE NORTHERLY...LAKE EFFECT COMPONENT SHOULD ONLY
ADD A FEW INCHES AT MOST. STORM TOTALS FOR THE TRI-CITIES LOOK TO BE
FROM 2 TO 3 INCHES. ACROSS THE THUMB...WILL LIKELY SEE 3 TO 4
INCHES...WITH SOME 5 INCH AMOUNTS CLOSER TO THE LAKE HURON
SHORELINE.

LONG TERM...WEDNESDAY THROUGH NEXT TUESDAY

LIGHT SNOW SHOWERS WILL QUICKLY END ACROSS SOUTHEAST MICHIGAN
WEDNESDAY MORNING AS DRY AIR FILTERS IN BEHIND THE DEPARTING LOW
PRESSURE SYSTEM. WITH MOISTURE LIMITED TO THE LOWEST 4K FT IN THE
COLUMN ONLY FLURRIES ARE EXPECTED ACROSS MUCH OF THE CWA WEDNESDAY
AFTERNOON. NORTH NORTHWESTERLY WINDS WILL CONTINUE THE SNOW CHANCES
ACROSS THE EXTREME EASTERN THUMB INTO THE AFTERNOON HOURS. A HIGH
PRESSURE RIDGE WILL BUILD IN OVERHEAD WEDNESDAY NIGHT AND THURSDAY.
WITH 850MB TEMPERATURES PLUMMETING INTO THE MID TEENS BELOW ZERO AND
SOME SCATTERING OUT OF THE CLOUDS...LOW TEMPERATURES SHOULD FALL
INTO THE SINGLE DIGITS ABOVE ZERO ACROSS MUCH OF THE CWA. WIND
CHILLS WILL ALSO BE QUITE COLD WEDNESDAY NIGHT...FALLING INTO THE
SINGLE DIGITS BELOW ZERO. WITH THE COLD LOW TEMPERATURES EXPECTED
THURSDAY MORNING AND CONTINUED COLD AIR ALOFT HIGH TEMPERATES ON
THURSDAY WILL STRUGGLE TO GET ABOVE 20.

DESPITE A RIDGE OF HIGH PRESSURE IN PLACE THURSDAY NIGHT AND
FRIDAY...A FAIRLY STRONG SHORTWAVE WILL TRACK THROUGH THE CENTRAL
GREAT LAKES DURING THIS TIME PERIOD. THE SHORTWAVE BRINGS IN ENOUGH
CLOUDS TO PREVENT MUCH IN THE WAY OF RADIATIONAL COOLING THURSDAY
NIGHT. IN FACT THERE IS ENOUGH MOISTURE AND LIFT TO PUT IN A SMALL
CHANCE FOR SNOW SHOWERS THURSDAY NIGHT AND FRIDAY. WITH THE MOISTURE
STREAMING IN WILL RAISE MIN TEMPERATURES THURSDAY NIGHT AND
INTRODUCE LOW POPS FOR SNOW THURSDAY NIGHT AND FRIDAY.

A FAIRLY STRONG CLIPPER SYSTEM TRACKING THROUGH NORTHERN LOWER
MICHIGAN WILL BRING A COUPLE INCHES OF SNOWFALL ACCUMULATION ON
SATURDAY. THE MODELS HAVE BEEN VERY CONSISTENT WITH TIMING OF THIS
FEATURE TRACKING THROUGH THE AREA...ALTHOUGH THE TRACK HAS SHIFTED A
BIT SOUTHWARD FROM RUN TO RUN. WITH THE LOW CLOSER TO THE CWA THERE
WILL BE PLENTY OF LIFT WITH OMEGA VALUES OF 3 TO 6 MICROBARS. WITH
280-290K MIXING RATIOS OF 1.5 TO 2.5 G/KG AND THE ADDITIONAL LIFT
PROVIDED BY THE COLD FRONT THE CHANCE OF MEASURING DURING THE DAY ON
SATURDAY IS HIGH ENOUGH TO WARRANT INCREASING POPS INTO THE LIKELY
CATEGORY.

NORTHWEST FLOW OVER THE GREAT LAKES WITH A SERIES OF SHORTWAVES
EJECTING FROM A LARGE UPPER LEVEL LOW PRESSURE OVER THE GULF OF
ALASKA WILL MAINTAIN SNOW CHANCES SUNDAY AND MONDAY. A STRONGER LOW
TRACKING THROUGH THE OHIO VALLEY ON TUESDAY COULD BRING US ANOTHER
ROUND OF ACCUMULATING SNOW DEPENDING ON THE CONNECTION WITH A WEAKER
SECONDARY LOW TRACKING THROUGH THE NORTHERN GREAT LAKES. AT THIS
TIME THE ECMWF MAINTAINS ENOUGH DISTANCE BETWEEN THESE SYSTEMS FOR
LITTLE IMPACT ACROSS SOUTHEAST MICHIGAN WHILE THE GFS PHASES THESE
SYSTEMS ENOUGH FOR A FEW INCHES OF SNOW ON TUESDAY. GIVEN THE ACTIVE
PATTERN IN PLACE ACROSS THE GREAT LAKES WILL GO WITH A 30 PERCENT
CHANCE UNTIL A CLEARER SOLUTION EMERGES FROM THE MODELS.

MARINE...

SNOW WILL CONTINUE TO SPREAD ACROSS THE CENTRAL GREAT LAKES TONIGHT
AS A LOW PRESSURE SYSTEM LIFTS ACROSS NORTHEAST OHIO AND INTO
NORTHERN PENNSYLVANIA. HEAVIER BURSTS OF SNOW WILL AT TIMES RESTRICT
VISIBILITIES TO 1/2 MILE OR LESS FROM CENTRAL LAKE HURON SOUTHWARD.

NORTHERLY WINDS WILL INCREASE LATE TONIGHT AS THE LOW PRESSURE
SYSTEM TRACKS FROM LAKE ERIE TOWARDS THE EAST COAST. WIND GUSTS TO
30 KNOTS ARE LIKELY ACROSS THE OPEN WATERS OF LAKE HURON...ACROSS
OUTER SAGINAW BAY AND ACROSS THE NEARSHORE WATERS FROM PORT AUSTIN
TO HARBOR BEACH. A BRISK WIND ADVISORY IS NOW IN EFFECT THROUGH
TOMORROW EVENING FOR THE NEARSHORE WATERS. THE GUSTY WINDS WILL
SUBSIDE WEDNESDAY NIGHT AS THE AREA OF LOW PRESSURE MOVES UP THE
EAST COAST AND HIGH PRESSURE BEGINS TO BUILD IN FROM THE WEST.
