A LAKE EFFECT SNOW AND BLOWING SNOW ADVISORY MEANS LAKE-EFFECT
SNOW AND BLOWING SNOW IS FORECAST THAT WILL MAKE TRAVEL DIFFICULT
IN SOME AREAS. LAKE-EFFECT SNOW SHOWERS TYPICALLY ALIGN
THEMSELVES IN BANDS AND WILL LIKELY BE INTENSE ENOUGH TO DROP
SEVERAL INCHES IN LOCALIZED AREAS. IN ADDITION...VISIBILITIES
WILL BE LIMITED DUE TO BLUSTERY WINDS CREATING BLOWING AND
DRIFTING SNOW. USE CAUTION WHEN TRAVELING.

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE MARQUETTE MI
656 AM EST THU DEC 13 2007

...UPDATED FOR AVIATION...

.DISCUSSION...
MAIN FCST CONCERN IS THE LAKE ENHANCED/LAKE EFFECT EVENT THIS AFTN
THRU FRI MORNING.

WATER VAPOR IMAGERY AND RUC ANALYSIS SHOW SPLIT FLOW PATTERN
CONTINUING OVER THE CONUS. A POSITIVE TILT TROF IN THE SRN STREAM
EXTENDS FROM THE MID MISSISSIPPI VALLEY TO TX. ANOTHER SRN STREAM
SHORTWAVE WAS JUST OF THE SRN CA COAST. FARTHER UPSTREAM...SHORTWAVE
JUST OFF THE BRITISH COLUMBIA COAST WILL SEND ENERGY INTO THE SRN
STREAM WHICH WILL COMBINE WITH CA SHORTWAVE TO SPIN UP A SIGNIFICANT
LWR MISSISSIPPI VALLEY TO NEW ENGLAND STORM THIS WEEKEND. IN THE NRN
STREAM...ATTENTION IS ON THE POTENT SHORTWAVE OVER SRN MANITOBA/ERN
DAKOTAS. SYSTEM HASNT LOST ANY STRENGTH SINCE MOVING ONSHORE IN
BRITISH COLUMBIA 24HRS AGO AS IMPRESSIVE HEIGHT FALLS CONTINUE ALONG
ITS TRACK. 00Z SOUNDING AT KGGW IN NE MT INDICATED A 12HR HEIGHT
FALL OF 170M AT 500MB. ALTHOUGH A MOISTURE CONNECTION IS LACKING...
THERE IS A RIBBON OF DEEP MOISTURE ASSOCIATED WITH THE SHORTWAVE AS
SHOWN BY KBIS SOUNDING. PROFILE WAS MOSTLY SATURATED THRU THE COLUMN
WITH PRECIPITABLE WATER 205PCT OF NORMAL. STRONG DEEP LAYER FORCING
WITH SHORTWAVE IS MOSTLY CENTERED JUST N OF THE U.S./CANADA BORDER
PER RUC ANALYSIS WHERE RADARS INDICATE A SHIELD OF SNOW SPREADING
INTO NRN ONTARIO. TAIL OF FORCING DOES EXTEND S INTO MN AND IS
RESULTING IN A NARROW BAND OF SNOW INTO NRN MN ALONG RIBBON OF DEEP
MOISTURE. DESPITE ONGOING WAA/ISENTROPIC ASCENT REGIME OVER THE
UPPER LAKES...NO PCPN IS OCCURRING DUE TO THE VERY DRY AIRMASS OVER
THE AREA AS SHOWN BY 00Z KINL/KGRB/KMPX SOUNDINGS. AT THE
SFC...ASSOCIATED LOW PRESSURE WAS LOCATED IN EXTREME SE MANITOBA

00Z MODEL RUNS SHOW NO SIGNIFICANT CHANGES WITH SYSTEM AS IT CROSSES
THE UPPER GREAT LAKES TODAY. 6HR 500MB HEIGHT FALLS ARE STILL
PROGGED TO BE NEARLY 100M. ALTHOUGH THE STRONGEST DEEP LAYER FORCING
WILL PASS JUST N OF UPPER MI...SWD EXTENSION OF FORCING COINCIDING
WITH RIBBON OF DEEP LAYER MOISTURE PER 00Z KBIS SOUNDING SHOULD
YIELD A BAND OF -SN PASSING ACROSS THE FCST AREA. ALTHOUGH THERE IS
A LOT OF DRY AIR OVER THE AREA NOW...IT APPEARS MODELS MAY BE A
LITTLE DEFICIENT WITH THE POPS/PCPN AMOUNTS ACROSS THE FCST AREA AS
RIBBON OF DEEP MOISTURE/FORCING PASSES OVER THE AREA. WILL THUS
SPREAD A SHORT PERIOD OF LIKELY POPS ACROSS THE N WHERE SATURATION
POTENTIAL IS A LITTLE BETTER. WILL KEEP CHC POPS ACROSS THE S. SNOW
ACCUMULATION WILL BE UNDER 1 INCH WITH THIS BRIEF PERIOD OF -SN. AS
FOR LAKE EFFECT...WINDS WILL HAVE JUST ENOUGH SRLY COMPONENT OVER
LAKE MICHIGAN TO ALLOW FOR THE POTENTIAL OF BRIEF LAKE ENHANCEMENT
OR AT LEAST LOW-LEVEL MOISTENING AS BAND OF FORCING PASSES EARLY
THIS AFTN. STILL ACCUMULATIONS SHOULDNT BE MORE THAN 1 INCH. TO
THE W...WINDS WILL BECOME MORE WRLY AT THE END OF THE PERIOD OF DEEP
LAYER FORCING. SO...LAKE ENHANCEMENT WONT BE TAKEN FULL ADVANTAGE
OF. STILL...THERE IS AN OPPORTUNITY FOR MAYBE A FEW INCHES OF SNOW
DURING THE DAY OVER THE KEWEENAW. THE BIGGER IMPACT WILL BE THE
STRONG WINDS THAT DEVELOP IN THE AFTN/EVENING. ISALLOBARIC WIND
COMPONENT WILL BE ALIGNED WITH THE WRLY BOUNDARY LAYER WIND (A
FAVORABLE DIRECTION FOR STRONG WINDS ON THE KEWEENAW). WITH 35-40KT
AVBL WITHIN 3KFT OF THE GROUND AND A HEALTHY ISALLOBARIC PUSH...
WINDS WILL LIKELY BE STRONGER THAN GUIDANCE INDICATES LATE
AFTN/EARLY EVENING...AND BLSN WILL BE A BIG ISSUE IN OPEN AREAS.
POTENT APPEARANCE OF SHORTWAVE ON WATER VAPOR IMAGERY IS ALSO
SUPPORTIVE OF GOING ABOVE MODEL GUIDANCE ON WINDS. THIS INCLUDES
OVER LAKE SUPERIOR WHERE GALES ARE A GOOD BET. A COUPLE OF OBS IN ND
HAVE ALREADY INDICATED GUSTS ABOVE 35KT EARLY THIS MORNING... AN
INDICATION OF WHAT SHOULD OCCUR OVER LAKE SUPERIOR AND THE KEWEENAW.
WILL RIDE WITH THE ADVY FOR THE KEWEENAW...BUT WILL HIT THE BLSN
ASPECT HARDER IN THE ADVY STATEMENT. WILL NEED TO WATCH FOR THE
POSSIBILITY OF UPGRADING TO A WARNING IF IT APPEARS SEVERAL HRS OF
SIGNIFICANT BLSN WILL OCCUR. AS FOR HEADLINES...HAD TO MAKE SOME
CHANGES TO INCLUDE BLSN IN SOME OF THE ADVY HEADLINES SINCE THAT IS
DEFINITELY NEEDED. WITH THAT CHANGE BEING MADE...HEADLINE TYPES
WERE ALSO CHANGED TO LAKE EFFECT SNOW.

ACROSS THE REST OF THE COUNTIES BORDERING LAKE SUPERIOR...SECOND
COLD FRONT WILL SWEEP ACROSS THE AREA THIS EVENING...SHIFTING WRLY
WINDS TO THE NW. THIS SHOULD RESULT IN A BRIEF PERIOD OF MDT
(PERHAPS HVY) SNOW AND BLSN. NW-SE ORIENTED WIND PARALLEL LES REGIME
SHOULD THEN QUICKLY SETUP...SUPPORTING HEAVIER SNOW ACCUMULATIONS
FOR ONTONAGON/GOGEBIC...THE HURON MOUNTAINS AND ERN
MARQUETTE/ALGER/LUCE. HOWEVER...THERE IS SOME QUESTION ABOUT HOW
MUCH LOWERING OF INVERSION OCCURS DURING THE NIGHT. THE GFS LOWERS
INVERSION DOWN TO 3-5KFT WHILE NAM IS NO LWR THAN 6-8KFT...HIGHEST
OVER THE E. THIS HAS IMPORTANT IMPLICATIONS FOR HEADLINES...
ESPECIALLY E OF KMQT...AS NAM SCENARIO WOULD SUPPORT ACCUMULATIONS
GETTING INTO WARNING CRITERIA. WILL LEAN SOMEWHAT TOWARD THE GFS AS
THE CANADIAN/UKMET LEND SOME SUPPORT FOR THE GFS IDEA OF UPPER TROF
SHIFTING E AND CYCLONIC FLOW RELAXING A LITTLE QUICKER THAN THE NAM
INDICATES. AFTER A SURGE OF STRONG/GUSTY WINDS WITH FROPA...WINDS
OVER THE W AND INLAND OVER THE E WILL RELAX DURING THE OVERNIGHT...
RESULTING IN DIMINISHING OF BLOWING/DRIFTING SN. WINDS WILL REMAIN
FAIRLY STRONG/GUSTY NEAR THE LAKESHORE E OF KMQT THRU THE NIGHT.

NNW FLOW LES IS EXPECTED FRI AS 850MB TEMPS ONLY MODERATE FROM -17C
IN THE MORNING TO -15C BY EVENING. WITH INVERSIONS RUNNING 3-5KFT
AND SFC HIGH PRES BUILDING INTO THE UPPER LAKES DURING THE
DAY...RESULTING IN INCREASINGLY ANTICYCLONIC FLOW (ESPECIALLY OVER
WRN LAKE SUPERIOR)...SNOW ACCUMULATIONS WILL GENERALLY BE ON THE
LIGHT SIDE (1 TO 4 WITH LOCALLY 5 INCHES). HIGHER ACCUMULATIONS WILL
BE OF KMQT WITH LONGER FETCH AVBL ACROSS LAKE SUPERIOR.
PRECONDITIONING FROM UNFROZEN LAKE NIPIGON SHOULD RESULT IN ONE OR
TWO DOMINANT BANDS. AWAY FROM LAKE EFFECT...DRY WEATHER IS EXPECTED.
WILL FAVOR THE COOLER GFS MOS FOR HIGHS GIVEN SOURCE REGION OF THE
CHILLY AIRMASS THAT WILL BE OVER THE AREA.

LES WILL DIMINISH/END FROM W TO E FRI NIGHT AS HIGH PRES SLIDES
ACROSS THE UPPER LAKES...RESULTING IN WINDS BECOMING SW BY SAT
MORNING. THERE MAY BE AN OPPORTUNITY FOR A MESOLOW TO DEVELOP OVER
ERN LAKE SUPERIOR UNDER THE PERIOD OF LIGHT WINDS. SHOULD ONE
DEVELOP...ANY ENHANCED LES THAT WOULD RESULT WILL NOT AFFECT UPPER
MI SINCE WINDS BECOME SW LATE IN THE NIGHT. WITH HIGH PRES PASSING
OVER THE AREA AND LAKE EFFECT CLOUDS DEPARTING...IT SHOULD BE A COLD
NIGHT...ESPECIALLY WITH MIN PRECIPITABLE WATER AROUND 0.1 INCHES
OVER THE AREA. WHILE THERE MAY BE SOME HIGH CLOUDS TO CONTEND
WITH...WILL STILL GO AT OR BLO THE COOLER GFS MOS GUIDANCE GIVEN THE
OTHER FAVORABLE RADIATIONAL COOLING FACTORS.

&&

.AVIATION (FOR THE 12Z TAF ISSUANCE)...

MAIN CONCERN IS FOR RESTRICTED VSBY DUE TO SNOW/BLOWING SNOW AT KCMX
THIS AFTERNOON. A LOW LEVEL JET OVER THE AREA WILL CAUSE A WIND
SHEAR EARLY THIS MORNING. THE WINDS WILL MIX DOWN CAUSING GUSTY
CONDITIONS BY LATE MORNING...THUS WILL DROP THE SHEAR AT THAT TIME.
UPPER TROF/SFC LOW CONTINUES TO APPROACH THE REGION...WITH LIGHT
SNOW DEVELOPING AS SFC TROF APPROACHES THE KEWEENAW THIS MORNING.
WESTERLY WINDS PICK UP WITH TIGHTENING PRES GRADIENT...WITH
STRONGEST WINDS ASSOCIATED WITH THE PASSAGE OF COLD FRONT IN THE
EARLY AFTERNOON. COMBINATION OF SNOW AND BLOWING SNOW TO PRODUCE
IFR/LIFR CONDITIONS THROUGH THE AFTERNOON AND EVENING. AT
KSAW...MVFR CONDITIONS DEVELOP AS PASSAGE OF SFC TROF BRINGS IN
STRATUS IN THE AFTERNOON...BUT STRONGER WINDS HOLD OFF UNTIL CFROPA
AFTER 0Z FRI.

&&

.MARINE (FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE)...

THE LOW PRESSURE AREA WILL MOVE ACROSS SOUTH CENTRAL CANADA TODAY
BECOMING JUST NORTH OF WAWA THIS EVENING. THIS LOW WILL TRACK INTO
SOUTHEAST QUEBEC LATE TONIGHT. WIND GUST AS HIGH AS 37KNOTS ARE
BEING REPORTED OVER THE DAKOTAS THIS MORNING WITH THIS SYSTEM. IF
THIS PERSIST...GALE FORCE GUSTS WILL MOVE OF THE LAKE LATE THIS
AFTERNOON. MEANWHILE...A RIDGE OF HIGH PRESSURE WILL MOVE INTO THE
NORTHERN MINNESOTA THIS EVENING BRINGING LIGHTER WINDS TO THE AREA.
SOUTH TO SOUTHWEST WINDS OF 20-30KT WILL DEVELOP AHEAD OF THE LOW
TONIGHT AND THIS MORNING. BEHIND THE LOW THERE WILL BE A SHORT
PERIOD OF NORTHWEST GALES TONIGHT...MAINLY OVER CENTRAL AND EASTERN
LAKE SUPERIOR. ANOTHER RIDGE WILL MOVE THROUGH LAKE SUPERIOR ON
FRIDAY AND FRIDAY EVENING. ANOTHER LOW WILL RACE ACROSS NORTHERN
ONTARIO ON SATURDAY BRINGING STRONG GUSTY WINDS TO THE LAKE AGAIN.
