AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
650 AM EST THU DEC 17 2015
.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 433 AM EST THU DEC 17 2015
A 991MB SURFACE LOW IS CURRENTLY LOCATED JUST TO THE NORTH OF LAKE
SUPERIOR AND IS SWEEPING A SECONDARY TROUGH EAST ACROSS UPPER
MICHIGAN EARLY THIS MORNING. THIS HAS SHIFTED THE WINDS TO MORE OF A
WESTERLY WIND AND QUICKLY INCREASED WINDS OVER THE KEWEENAW
PENINSULA (GUSTS UP TO 38KTS AT KCMX). HAVE ALSO SEEN THE
PRECIPITATION TRANSITION FROM -RA/DZ TO SNOW ACROSS THE CENTRAL U.P.
WHILE LIGHT SNOW CONTINUES OVER THE WESTERN U.P. ON THE BACKSIDE OF
THE SURFACE AND MID-LEVEL LOW. THIS SNOW HAS BEEN HELPED BY A
SECONDARY SHORTWAVE PIVOTING THROUGH THE AREA...BUT WITH THE
SURFACE/UPPER LOW LIFTING NORTH-NORTHEAST THROUGH THE MORNING...MUCH
OF THE DEEP MOISTURE GOES WITH IT AND WOULD EXPECT THE SNOW SHOWERS
TO DIMINISH THROUGH THE MORNING OUTSIDE OF THE LAKE ENHANCED AREAS
FAVORED BY WESTERLY WINDS.
AS FOR THE LAKE EFFECT...EXPECT LAKE EFFECT OVER THE WEST-SOUTHWEST
WIND LOCATIONS THIS MORNING AS COLD AIR MOVES OVER THE RELATIVELY
WARM (AROUND 4C) LAKE SUPERIOR WATERS. ANOTHER MID-LEVEL TROUGH
SLIDES THROUGH THE REGION THIS AFTERNOON...BRINGING DEEPER MOISTURE
AND RAISING INVERSION HEIGHTS OVER LAKE SUPERIOR. THAT WILL LEAD TO
A VERY FAVORABLE PERIOD OF LAKE EFFECT FOR THE WEST TO SLIGHTLY WEST-
SOUTHWEST WIND SNOW BELTS INTO FRIDAY. AS FOR SOME OF THE
SPECIFICS...DELTA-T VALUES DROP TO AROUND 19 WITH THE 850MB TEMPS
FALLING TO -15C BY 06Z FRIDAY. MODELS SHOWING LAKE INDUCED CAPE A
TOUCH OVER 500 J/KG AND WITH MUCH OF THE FORCING WITHIN THE
DGZ...SHOULD SEE DECENT SNOW RATIOS. DO THINK THE STRONGER WINDS
WILL FRACTURE THE FLAKES THIS AFTERNOON AND TONIGHT...SO DIDN/T GO
MUCH OVER 20-1 FOR THE SNOW RATIO. THEREFORE...ARE EXPECTING A VERY
FAVORABLE PERIOD FOR MODERATE TO OCCASIONALLY HEAVY LAKE EFFECT
SNOW. NAM (AND TO SOME EXTENT THE GEM-REGIONAL AND GFS) CONTINUES TO
SHOW A SLIGHT BACKING OF THE LOW LEVEL WHICH WOULD INCREASE
CONVERGENCE AND LEAD TO A STRONGER BAND SOMEWHERE OVER FAR NORTHERN
HOUGHTON AND KEWEENAW COUNTY LATE THIS AFTERNOON INTO EARLY EVENING.
THAT SHOULD LIMIT THE SNOWFALL FOR AREAS SOUTH OF HOUGHTON UNTIL
ANOTHER TROUGH SLIDES THROUGH LATE TONIGHT AND SHIFTS WINDS MORE
WESTERLY. FOR TODAY INTO TONIGHT...HAVE SNOWFALL AMOUNTS OF 4-8
INCHES FOR NORTHERN HOUGHTON AND KEWEENAW COUNTIES...WITH MOST OF
THAT FALLING FROM LATE THIS AFTERNOON INTO TONIGHT. THAT PUTS THE
AMOUNTS JUST UNDER THE 8 INCH AND 12HR CRITERIA FOR A
WARNING...ALTHOUGH THE VERY GUSTY WINDS WILL LEAD TO BLOWING AND
DRIFTING SNOW THAT COULD WARRANT ISSUING A WARNING. BUT WITH THE
STRONGEST BAND EXPECTED TO MOVE AROUND A BIT TONIGHT INTO
FRIDAY...DIDN/T HAVE ENOUGH CONFIDENCE TO GO WITH A WARNING AND
AFTER COORDINATION WITH THE LONG TERM SHIFT OPTED TO ISSUE AN
ADVISORY FOR THE LONG DURATION EVENT.
OUTSIDE THE MAIN LAKE EFFECT AREA OVER THE KEWEENAW...DO EXPECT SOME
LIGHT SNOW SHOWERS OVER THE WEST THIS AFTERNOON IN ASSOCIATION WITH
THE SHORTWAVE AND DEEPER MOISTURE. OTHERWISE...EXPECT THE REST OF
THE AREA TO SEE A MOSTLY CLOUDY SKY WITH THE LAKE EFFECT STAYING OFF
SHORE OF ALGER/LUCE COUNTIES FOR MUCH OF THE NIGHT.
.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 508 AM EST THU DEC 17 2015
CONCERNS FOCUS ON POTENTIAL FOR ONGOING MODERATE TO OCCASIONALLY
HEAVY LAKE EFFECT SNOW OVER THE KEWEENAW PENINSULA LATE TONIGHT INTO
FRI EVENING.
FAIRLY PROGRESSIVE PATTERN FOR LONG TERM WILL START OUT WITH THE
UPPER GREAT LAKES IN A WNW COLD ADVECTION PATTERN IN THE WAKE OF THE
STORM SYSTEM NOW LIFTING NORTH OF LAKE SUPERIOR. THE COLD ADVECTION
COMBINED WITH DEEPENING MOISTURE AND WEAK ENHANCEMENT COULD GENERATE
PERIODS OF MODERATE TO POSSIBLY HEAVY LES OVER W-NW SNOWBELTS OF
LAKE SUPERIOR INTO FRI NIGHT. BROAD MID-LVL RIDGING BUILDING ACROSS
THE CENTRAL CONUS WILL THEN LEAD TO BRIEF PERIOD OF MILDER AND
GENERALLY QUIET WEATHER FOR THE WEEKEND BEFORE ANOTHER IN A SERIES
OF PLAINS SYSTEMS BRINGS A CHANCE OF MORE PRECIPITATION FOR THE FIRST
HALF OF NEXT WEEK.
FRI INTO FRI NIGHT...PER 00Z MODEL CONSENSUS...COLD ADVECTION IN THE
WAKE OF PLAINS SYSTEM LIFTING NORTH OF LAKE SUPERIOR WILL LOWER 850
MB TEMPS DOWN TO -16 TO -19C BY FRI AFTERNOON AND FRI NIGHT.
MODEL SOUNDINGS SUGGEST A NUMBER OF FACTORS COMING TOGETHER FOR THE
POTENTIAL OF MODERATE TO POSSIBLY HEAVY LAKE EFFECT SNOWFALL OVER
THE KEWEENAW PENINSULA...ESPECIALLY BEGINNING LATE TONIGHT AND
CONTINUING INTO FRI EVENING. FIRST OFF...THE HEART OF THE COLDEST
850 MB TEMPS WILL BE MOVING ACROSS LAKE SUPERIOR AT THIS TIME WHICH
WILL GREATLY INCREASE INSTABILITY. SECONDLY...MODELS HINT THAT A
COUPLE OF SHORTWAVES WILL DIVE DOWN FROM SOUTH CENTRAL CANADA
THROUGH BASE OF BROAD MID-LVL TROUGH OVER THE NCNTRL CONUS PROVIDING
DEEPER MOISTURE (TO NEAR 350 MB PER FORECAST SOUNDINGS) WHILE
LIFTING INVERSIONS AND PROVIDING AN OPPORTUNITY FOR WEAK ENHANCEMENT
TO LAKE EFFECT. PLUGGING IN A WESTERN LAKE SUPERIOR TEMP OF 42F
YIELDS IMPRESSIVE LAKE INDUCED CAPE VALUES FROM 550-625 J/KG BY
FRIDAY WITH LAKE INDUCED EQUILIBRIUM HEIGHTS FM 9-10 KFT. BEST MODEL
OMEGA/LIFT DOES INTERSECT DGZ ON FRIDAY WHICH WILL ALSO CONTRIBUTE
TO FAVORABLE SNOW GROWTH. LAKE INDUCED TROUGHING ADVERTISED BY HIGH
RESOLUTION MODELS IN RESPONSE TO COLDER AIR MOVING OVER REGION WILL
ENHANCE LOW-LEVEL CONVERGENCE IN WESTERLY FLOW....LIKELY ALLOWING
FOR A INTENSE DOMINANT W-E LES TO FORM. GIVEN ALL THE FAVORABLE
FACTORS AND FAIRLY GOOD MODEL AGREEMENT WILL CONTINUE LES ADVISORY
INTO FRI NIGHT OVER THE KEWEENAW. FEEL FAIRLY CONFIDENT THAT TOTAL
LES ACCUMULATION WILL EXCEED A FOOT IN SEVERAL PLACES OVER THE
KEWEENAW PENINSULA....MAINLY FROM TWIN LAKES TO CALUMET. THE
WESTERLY WINDS GUSTING NEAR 35 MPH WILL ALSO CAUSE CONSIDERABLE
BLOWING SNOW AND OCCASIONAL WHITEOUT CONDITIONS AT TIMES.
WINDS BACKING WSW OVER ERN UPPER MI FROM LAKE INDUCED TROUGHING
SHOULD KEEP ANY DOMINANT W-E LES BAND THAT FORMS OFFSHORE OF ERN
COUNTIES OF CWA UNTIL AT LEAST LATE FRI. PASSAGE OF SFC TROUGH LATE
FRI INTO FRI EVENING WILL BEGIN TO VEER WINDS AROUND MORE WNW AND
THEN COULD BRING MODERATE TO HEAVY LES AND BLOWING SNOW INTO
PORTIONS OF ERN ALGER-LUCE AND POSSIBLY NRN SCHOOLCRAFT AND FOR THE
WEST INTO NORTHERN ONTONAGON...SRN HOUGHTON AND NORTHERN BARAGA
COUNTIES FRI NIGHT INTO EARLY SAT. THESE LOCATIONS WILL LIKELY ALSO
NEED A LES ADVISORY FOR LATE FRI INTO FRI NIGHT/SAT MORNING BUT
SINCE EVENT WILL TAKE PLACE MAINLY IN THE 4TH INTO 5TH FORECAST
PERIODS WILL NOT ISSUE HEADLINE JUST YET.
THIS WEEKEND...LINGERING WNW LES SHOULD BEGIN TO WIND DOWN FROM WEST
TO EAST SATURDAY AFTERNOON AS COLDEST AIR MOVES WELL EAST AND THE
HIGH PRESSURE RIDGE BUILDING IN FROM THE WEST RESULT IN LARGE SCALE
ANTICYCLONIC WIND FLOW AND BEGINS TO LOWER INVERSION HGTS BLO
5KFT.EXPECT QUIETER/DRIER WEATHER SAT NIGHT INTO SUNDAY WITH BROAD
MID-LVL RIDGE MOVING ACROSS OVER THE AREA. MAY BE A FEW LINGERING
LAKE EFFECT SNOW SHOWERS SAT NIGHT AS WEAKENED TROUGH PERSISTS OVER
NRN LAKE SUPERIOR.
SUNDAY NIGHT INTO WEDNESDAY...WEATHER LOOKS TO BECOME MORE ACTIVE
AGAIN FOR SUN NIGHT INTO MONDAY AS SLIGHTLY NEG-TILT SHORTWAVE
TROUGH AND ASSOC SFC LOW LIFT NE FROM THE CENTRAL PLAINS. THE 00Z
GFS HAS TRENDED TOWARD THE MORE CONSISTENT ECMWF AND ARE NOW IN GOOD
AGREEMENT SHOWING A SFC LOW TRACK ACROSS NRN LAKE MI/CLOSE TO
MACKINAC STRAITS BY LATE SUN NIGHT/EARLY MON. THERMAL PATTERNS/GFS
SOUNDING PROFILES SUGGEST MOSTLY SNOW WEST HALF WITH GENERALLY A MIX
OF SNOW/RAIN FOR THE EAST HALF AND LIKELY MORE RAIN FOR LOCATIONS
NEAR LAKE MI FOR SUN NIGHT INTO MON MORNING. AS SYSTEM MOVES EAST ON
MON AFTERNOON...PTYPE WILL CHANGE TO MOSTLY LIGHT SNOW ACROSS CWA.
AT THIS POINT WITH CONSENSUS QPF GENERALLY RANGING FROM .10 TO
.20...SNOW AMOUNTS APPEAR WILL BE MINIMAL WITH THIS SYSTEM...NO MORE
THAN AN INCH OR TWO. WITH SYSTEM EXITING EAST WEATHER LOOKS QUIET
FOR MON NIGHT AND TUE. GFS AND ECMWF ADVERTISE ANOTHER SYSTEM
APPROACHING FROM THE PLAINS WHICH COULD BRING MORE MIXED PCPN INTO
THE AREA LATE WED.

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING)
ISSUED AT 650 AM EST THU DEC 17 2015
WITH THE LOW DEPARTING THE AREA...WINDS ARE SHIFTING TO THE WEST
BEHIND THE SURFACE TROUGH THAT IS MOVING THROUGH CENTRAL UPPER
MICHIGAN. THE WESTERLY WINDS COMBINED WITH COLD AIR MOVING OVER THE
RELATIVELY WARM LAKE SUPERIOR WATERS WILL LEAD TO LAKE EFFECT OVER
THE NEXT COUPLE OF DAYS...ESPECIALLY AT KCMX. HAVE THE WORST
CONDITIONS THERE THROUGH THE TAF PERIOD...WITH THE HEAVIEST SNOW
FALLING LATE THIS AFTERNOON THROUGH FRIDAY. AT THE OTHER TWO
SITES...THE WINDS ARE NOT FAVORABLE FOR LAKE EFFECT...BUT SOME
LIGHT SNOW SHOWERS ARE EXPECTED THIS MORNING BEFORE THE MAIN
ENERGY ASSOCIATED WITH THE LOW LIFTS NORTH AND OUT OF THE AREA.
THAT WILL LEAD TO A TRANSITION TO VFR CONDITIONS AT KSAW...WHILE
KIWD STAYS AT MVFR.

.MARINE...(FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE)
ISSUED AT 433 AM EST THU DEC 17 2015
A LOW JUST TO THE NORTH OF LAKE SUPERIOR WILL CONTINUE NORTH TO
NORTHERN JAMES BAY BY THIS EVENING. A TIGHT PRESSURE GRADIENT AND
COLD AIR SURGING ACROSS THE LAKE WILL LEAD TO WESTERLY GALES OF
35-40KTS OVER MUCH OF THE LAKE TODAY INTO TONIGHT. GALES TO 35KTS
ARE EXPECTED TO CONTINUE INTO FRIDAY NIGHT OR SATURDAY MORNING FOR
MOST OF THE LAKE...SO HAVE EXTENDED THE GALE WARNINGS TO THOSE
TIMES. A SURFACE RIDGE WILL SLIDE ACROSS THE UPPER GREAT LAKES
REGION ON SATURDAY AND SATURDAY NIGHT...LEADING TO WINDS FALLING
BELOW 20KTS. BUT THE LIGHTER WINDS WILL BE SHORT LIVED AS ANOTHER
LOW PRESSURE SYSTEM DEVELOPS IN THE CENTRAL PLAINS ON SATURDAY NIGHT
AND LIFTS NORTHEAST THROUGH THE GREAT LAKES REGION SUNDAY NIGHT INTO
MONDAY. AT THIS TIME...NORTHERLY WINDS UP TO 30KTS ARE EXPECTED ON
MONDAY.
