AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1257 PM EST MON DEC 13 2010

.UPDATE...
BLIZZARD HEADLINE WAS EXPANDED AND EXTENDED...NOW INCLUDING BOTH HURON AND
SANILAC COUNTIES AND LASTING THROUGH 7 AM TUESDAY MORNING. RADAR
AND SATELLITE DATA SHOWS A STRONG AND PERSISTENT BAND OF LAKE
EFFECT SNOW REMAINING OVER THE THUMB. FORECAST MODEL SOUNDINGS FOR
SOUTHERN LAKE HURON SHOW VERY STRONG LAKE EFFECT POTENTIAL (LAKE
INDUCED CAPE VALUES AROUND 1000 J/KG) LASTING THROUGH LATE TOMORROW.
DETERMINING FACTOR FOR WHEN THE SNOW WILL STOP OVER THE THUMB WILL
BE DE PENDANT ON WHEN A NORTHWEST SHIFT IN THE LOW-LEVEL WIND
FIELD WILL OCCUR. LATEST MODEL DATA DOES NOT SHOW A PRONOUNCED
SHIFT OCCURRING UNTIL ABOUT 7 AM TOMORROW...THEREFORE THE BLIZZARD
WARNING WAS EXPANDED THROUGH THEN. SNOWFALL RATES AVERAGING AN
INCH AN HOUR OR GREATER ARE LIKELY IN THE BAND...BRINGING
ADDITIONAL ACCUMULATIONS NEAR THE LAKESHORE TO AROUND ONE FOOT.
NEARSHORE MARINE SITES HAVE BEEN RECORDING GUSTS BETWEEN 45 AND 50
MPH...AND EXPECT THIS TO CONTINUE AS WELL. THE COMBINATION OF
ADDITIONAL HEAVY SNOWFALL...STRONG NORTH WINDS...BLOWING
SNOW...LOW VISIBILITIES...AND COLD WIND CHILLS WILL BRING
DANGEROUS WINTER WEATHER CONDITIONS TO THE AREA OVERNIGHT.

FURTHER SOUTH OVER ST CLAIR COUNTY...ADDITIONAL SNOW ACCUMULATIONS
NEAR THE LAKESHORE ARE EXPECTED TO BE LIGHT...AND ISSUED A WINTER
WEATHER ADVISORY TO COVER LOW VISIBILITIES AND HAZARDOUS ROAD
CONDITIONS DUE TO PRIMARILY BLOWING SNOW CREATED BY STRONG GUSTY
WINDS NEAR THE LAKESHORE.

&&

.AVIATION...ISSUED 1224 PM EST MON DEC 13 2010

LAKE EFFECT SNOW SHOWERS HAVE BEEN CONFINED TO TERMINALS NORTH AND
EAST OF THE TAF SITES TODAY...BUT DET AND PTK WILL SEE MVFR CIGS AS
THESE CLOUDS ARE BLOWN SOUTHWARD FROM THE ROBUST NNW WINDS. HAVE A
TEMPO IN FNT FOR MVFR ALSO AS THEY COULD SEE CIGS DROP BRIEFLY BEING
ON THE EDGE OF THE CLOUD SHIELD. WINDS REMAIN GUSTY BUT THE ONLY
BLSN REPORTS HAVE BEEN MAINLY PTK AND NE FROM THERE. 30KT GUSTS ARE
HIGHEST FORECASTED...AND THE WINDS HAVE BEEN QUITE UNIFORM AND
CONSISTENT FROM 330 DEGREES...HOWEVER MAY SEE BRIEF GUSTS SLIGHTLY
HIGHER. HAVE DROPPED WINDS THIS EVENING BUT STILL GUSTING OVER 20KT
IN MOST PLACES.

&&

.PREV DISCUSSION...ISSUED 707 AM EST MON DEC 13 2010

UPDATE...

NOW THAT BLOWING AND DRIFTING SNOW HAS EASED SOMEWHAT WITH ONLY
OCCASIONAL VISIBILITIES DOWN TO SEVERAL MILES...WILL CANCEL THE
WINTER WEATHER ADVISORY. STEADY LIGHT SNOW SHOWERS OVERNIGHT HAVE
ALSO DIMINISHED TO FLURRIES. EXPECT LITTLE/NO ACCUMULATIONS FOR
MUCH OF THE AREA TODAY. LAKE EFFECT BANDS...HOWEVER...WILL
CONTINUE TO BRUSH THE NORTHERN THUMB SHORELINE...SO EXPECT MORE
ACCUMULATIONS IN LOCAL AREAS...ESPECIALLY NEAR LAKE HURON.
OTHERWISE...A VERY COLD DAY ON TAP WITH WIND CHILLS AT OR BELOW
ZERO.

&&

.PREV DISCUSSION...ISSUED 355 AM EST MON DEC 13 2010

SHORT TERM...TODAY

WILL MAINTAIN CURRENT HEADLINES WITH THIS ISSUANCE AND DO AN UPDATE
AT 12Z TO DROP THE TUSCOLA WARNING AND MOST LIKELY THE BLOWING SNOW
ADVISORY FOR THE REST OF THE AREA. WILL MAINTAIN THE WARNINGS FOR
HURON/SANILAC COUNTIES AS WIND GUSTS ALONG THE SHORELINE IN HURON
COUNTY REMAIN IN THE 45+ MPH RANGE AND LAKE EFFECT SNOW BANDS WILL
CONTINUE TO BRUSH BOTH COUNTIES INTO THE MORNING AND TO SOME DEGREE
THIS AFTERNOON AS WELL.

SYNOPTIC SCALE LIGHT SNOW ON THE VERY SOUTHERN EDGE OF STRETCHED OUT
DEFORMATION ZONE WILL DRIFT EAST/SOUTHEAST ACROSS THE CWA DURING THE
PRE-DAWN HOURS AND GRADUALLY WEAKEN FURTHER. ONCE THIS LIGHT SNOW IS
DONE...POCKETS OF LOWER VISIBILITIES FROM BLOWING SNOW WILL IMPROVE
A GREAT DEAL. DURING THE DAY...ANY ACCUMULATING SNOW WILL BE LIMITED
TO THE LAKE HURON SHORELINE OVER THE THUMB WITH JUST A FEW FLURRIES
ELSEWHERE.

TEMPERATURES HAVE FALLEN TO AROUND 10 DEGREES AND WILL EDGE DOWN A
FEW MORE DEGREES INTO THE EARLY MORNING. WITH GUSTY WINDS...WIND
CHILL READINGS WILL BOUNCE AROUND GENERALLY IN THE -5 TO -10 F AREA
THROUGH THE DAY AS TEMPERATURES REALLY WON/T IMPROVE MUCH AS ARCTIC
AIR CONTINUES TO RUSH INTO THE AREA. AFTERNOON HIGH TEMPERATURES
WILL HOLD AT AROUND 15 DEGREES OR LESS WILL ALL LOCATIONS OTHER THAN
THOSE IMMEDIATELY ADJACENT TO LAKE HURON WHERE WATER TEMPERATURES IN
THE 30S WILL MODERATE THE LOW LEVEL AIR ENOUGH TO BRING TEMPERATURES
AROUND 20.

LONG TERM...TONIGHT THROUGH SUNDAY

A DRY AND COLD AIRMASS WILL REMAIN OVER THE REGION THROUGH THE FIRST
HALF OF THE WEEK AS WE ARE ENTRENCHED WITHIN THE DEEP NORTHWESTERLY
FLOW ON THE BACK SIDE OF THE UPPER LEVEL TROUGH. MODEL SOUNDINGS
SHOW CLOUDS CLEARING OUT TONIGHT MAKING FOR A VERY COLD NIGHT AS
THE ARCTIC AIRMASS RESIDES OVERHEAD. THE PRESSURE GRADIENT WILL
REMAIN TIGHT ENOUGH TO MAINTAIN A 10-15 MPH WIND THROUGH THE NIGHT
YIELDING WIND CHILL VALUES OF -5 TO -15 DEGREES BELOW ZERO. THIS
IS ON THE FRINGES OF WIND CHILL ADVISORY CRITERIA AND THE DAY
SHIFT WILL NEED TO KEEP A CLOSE EYE ON TEMPS/WINDS FOR TONIGHT.

THE VERY COLD TEMPERATURES OVER THE LAND SHOULD HELP TO STRENGTHEN
THE THERMAL TROUGHING OVER LAKE HURON TONIGHT...HOPEFULLY ORIENTING
ANY REMAINING LAKE EFFECT SNOW SHOWERS OUT OVER THE WATER BY TUESDAY
MORNING. ADDITIONAL MINOR ACCUMULATIONS (2 INCHES OR LESS) REMAIN
POSSIBLE ACROSS EXTREME EASTERN HURON COUNTY AND NORTHEASTERN
SANILAC COUNTY...BUT THE THREAT SHOULD BE DIMINISHING AS WE PROGRESS
THROUGH THE NIGHT.

THE PRESSURE GRADIENT WILL GRADUALLY RELAX WITH A SURFACE RIDGE
BUILDING OVERHEAD ON WEDNESDAY AND WEDNESDAY NIGHT. TEMPERATURES
WILL ONLY UNDERGO GRADUAL MODIFICATION THROUGH THIS TIME AS WE HOLD
ONTO A NORTHWESTERLY WIND WITH A FRESH SNOWPACK AND HAVE UNDERCUT
GUIDANCE THROUGH WEDNESDAY NIGHT. WEDNESDAY NIGHT LOWS MAY NEED TO
BE LOWERED IF MID CLOUDS HOLD OFF WITH LIGHT WINDS AND GOOD
RADIATIONAL COOLING CONDITIONS IN PLACE.

BY THE LATER HALF OF THE WEEK...THE UPPER LOW OVER THE NEW ENGLAND
STATES WILL RETROGRADE BACK TO THE WEST AS SHORTWAVE ENERGY IS
EJECTED OUT OF THE GULF OF ALASKA...ESTABLISHING A BROAD LONGWAVE
TROUGH ACROSS NORTH AMERICA. A SERIES OF SHORTWAVE MOVING ACROSS THE
NORTHERN TIER OF THE UNITED STATES WILL MOVE THROUGH THE REGION FROM
THURSDAY INTO THE UPCOMING WEEKEND. ALTHOUGH SNOW SHOWERS WILL BE
POSSIBLE...MOISTURE WILL BE A LIMING FACTOR AND POPS AT THIS TIME
RANGE FROM JUST FLURRIES TO A LOW CHANCE LIGHT SNOW SHOWERS.

MARINE...

STRONG NORTH TO NORTHWEST WINDS WILL REMAIN IN PLACE ACROSS ALL
MARINE AREAS THROUGH THE EARLY THIS WEEK IN RESPONSE TO A TIGHTENING
PRESSURE GRADIENT BETWEEN THE DEPARTING WINTER STORM AND STRONG HIGH
PRESSURE BUILDING INTO THE NORTHERN PLAINS. SUSTAINED GALE FORCE
WINDS OF 35 TO 40 KNOTS WITH GUSTS TO 45 KNOTS CAN BE EXPECTED OVER
LAKE HURON TODAY WITH GUSTS TO 35 KNOT GALES OR BETTER FURTHER SOUTH
TO WESTERN LAKE ERIE...WITH THESE CONDITIONS PERSISTING INTO TUESDAY.
THE PERIOD OF STRONGEST WINDS WILL BE EARLY THIS MORNING WHEN GUSTS
WILL APPROACH STORM FORCE AT TIMES.

ARCTIC AIR WILL ALSO CONTINUE FUNNEL INTO THE AREA...LEADING TO
ABUNDANT SNOW SQUALLS AND HIGH WAVES EARLY THIS WEEK. WINDS WILL
SLOWLY DIMINISH DURING THE MIDDLE PART OF THE WEEK AS SURFACE HIGH
PRESSURE BUILDS OVER THE GREAT LAKES. THIS HIGH WILL ALSO LEAD TO A
STEADY DOWNTREND IN SNOW SHOWER ACTIVITY TUESDAY NIGHT INTO
