Lake-Effect Snow in Michigan, December 15, 2013

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
643 AM EST SUN DEC 15 2013

.SYNOPSIS...
ISSUED AT 220 AM EST SUN DEC 15 2013

A LINGERING AREA OF LOW PRESSURE WILL MOVE ACROSS NORTHERN MICHIGAN
TODAY...SPAWNING ADDITIONAL ACCUMULATING LAKE EFFECT SNOW. MOST OF
THE AREA WILL SEE A BRIEF LULL TONIGHT...BEFORE PLACES NEAR LAKE
MICHIGAN SEE MORE SNOW ON MONDAY. COLD TEMPERATURES WILL LAST INTO
MONDAY...BUT SOMEWHAT MILDER CONDITIONS WILL ARRIVE TUESDAY.

&&

.UPDATE...
ISSUED AT 643 AM EST SUN DEC 15 2013

-SN REMAINS WIDESPREAD. SOME ENHANCED CONVECTIVE ELEMENTS EXTEND
FROM GD TRAV BAY TO BEAVER ISL...AND PRESUMABLY INTO FAR WESTERN
MACKINAC CO. THESE ARE BEING INDUCED AS THE LAKES SPIN UP MULTIPLE
MESOLOWS ALONG THE BROADER SURFACE TROF EXTENDING FROM CENTRAL LAKE
HURON TO CENTRAL SUPERIOR. W/WNW 1000-850MB FLOW WILL CONTINUE
FROM GD TRAV BAY SOUTHWARD...TO THE NORTH THE LOW LEVEL FLOW WILL
REMAIN QUITE CONVOLUTED. NO SIGNIFICANT CHANGES NEEDED TO THIS
POINT...OUTSIDE OF MAKING SNOW A BIT MORE EXPANSIVE THIS MORNING
IN SE SECTIONS.

&&

.SHORT TERM...(TODAY THROUGH TONIGHT)
ISSUED AT 220 AM EST SUN DEC 15 2013

RATHER WIDESPREAD LIGHT SNOW CONTINUES AT THIS EARLY HOUR...COURTESY
OF LINGERING DEEP LAYER MOISTURE INTERACTING WITH WEAK SURFACE
TROUGH STRETCHING NORTHWEST TO SOUTHEAST ACROSS THE AREA.
SIGNIFICANT LAKE CONTRIBUTIONS HAVE ENDED FOR THE TIME BEING...
ALTHOUGH HAVE NOTICED SOME ILL-DEFINED RATHER STATIONARY LAKE BANDS
OVER NORTHERN LAKE MICHIGAN IN AREA OF MAX LOW LEVEL CONVERGENCE.
PATTERN REMAINS A VERY ACTIVE ONE THROUGH THE SHORT TERM
(TONIGHT)...AS ANOTHER SURGE OF STRONG CAA ON BACKSIDE OF SOUTHEAST
DIVING ONTARIO WAVE WILL RAMP UP THE LAKE PROCESSES ONCE AGAIN TODAY
INTO THIS EVENING. POTENTIAL DEFINITELY THERE FOR SOME SIGNIFICANT
SNOWS...ESPECIALLY IN PRESENCE OF OVERHEAD TROUGHING AND DECENT
BACKGROUND SYNOPTIC MOISTURE. EXACTLY WHERE AND JUST HOW MUCH
ANYTHING BUT A HIGH CONFIDENCE ENDEAVOR AS SAME TROUGHING AND
MATURATION OF LAKE INDUCED LOWS LOOK TO PLAY HAVOC WITH LOW LEVEL
WIND FIELDS. FORECAST CHALLENGES CENTER ON TRYING TO ANSWER THESE
UNCERTAINTIES...AS WELL AS ADDRESSING ASSOCIATED HEADLINE POTENTIAL.

A LOW CONFIDENCE FORECAST FOR SURE TODAY BASICALLY...A MESOSCALE
FORECASTING NIGHTMARE...WITH INCREASING LAKE PROCESSES SUPERIMPOSED
ON CHAOTIC LOW LEVEL WIND FIELDS VIA LAKE AGGREGATE REINFORCED
TROUGHING AND MESOSCALE LOW(S) DEVELOPMENT. STRONG SLUG OF MID LEVEL
SUPPORT EARLY THIS MORNING ONLY ADDING TO THE COMPLEXITY. LOW LEVEL
TROUGHING ESSENTIALLY STALLS THIS MORNING ACROSS NORTHEAST LOWER
INTO CENTRAL LAKE SUPERIOR...WITH NEARLY ALL HIGH RES GUIDANCE
SUPPORTING DUAL LOW PRESSURE DEVELOPMENT ALONG IT (BOTH OF WHICH ARE
ALREADY EVIDENT ON LATEST REGIONAL ANALYSIS)...ONE OVER NORTHERN
LAKE MICHIGAN...WITH THE MUCH MORE IMPRESSIVE CENTER OVER LAKE
SUPERIOR TIED TO STRONG MID LEVEL SUPPORT/SHORTWAVE. FOCUSED LOW
LEVEL CONVERGENCE AND LAKE MOISTURE CONTRIBUTION WILL KEEP SNOW
SHOWERS/AREAS OF LIGHT SNOW ALONG THIS TROUGHING THIS MORNING. LOCAL
WRF VERY DISCONCERTING IN THIS REGARD...PEGGING RATHER INTENSE SLOW
MOVING SNOW BAND UP NEAR THE STRAITS AND ALONG THE NORTHEAST LOWER
COASTLINE WHERE LAKE HURON MODIFIED AIR INTERCEPTS THIS BOUNDARY.
FOCUS FOR MORE PURE LAKE ENHANCEMENT OCCURS SOUTH OF THIS AXIS OVER
NORTHERN LAKE MICHIGAN AS DEVELOPING WEST NORTHWEST FLOW DROPS H8
TEMPERATURES BACK DOWN INTO THE NEGATIVE MID TEENS. MORE THAN ENOUGH
LAKE/AIR TEMPERATURE DIFFERENCE TO IGNITE THE LAKE GUNS. HOWEVER...
SLUG OF VERY DRY AIR ALSO ACCOMPANIES THE CAA...ESPECIALLY FOR AREAS
ALONG AND SOUTH OF GRAND TRAVERSE BAY. PRE-LAKE MODIFIED MODEL
SOUNDINGS AWFULLY DRY OVER WISCONSIN THIS MORNING...AND WOULD EXPECT
SHORT FETCH LENGTH TO PREVENT GOOD LAKE MODIFICATION. MUCH TOUGHER
CALL NORTH OF GRAND TRAVERSE BAY WHERE BETTER MOISTURE WILL RESIDE.
PRESENCE OF TROUGHING/MESOSCALE FEATURES WILL HAVE PLENTY TO SAY ON
LAKE SNOW MORPHOLOGY...BUT FEELING IS BURSTS OF MODERATE TO HEAVY
SNOW WILL SPREAD INLAND DURING THE MORNING. THINGS ONLY GET MORE
ENTERTAINING IN THE AFTERNOON...WITH STRONG SUPPORT FOR LAKE
SUPERIOR LOW TO DROP SOUTH INTO NORTHERN LAKE MICHIGAN...ENHANCING
LOW LEVEL CONVERGENCE...ALL THE WHILE MOISTURE DEPTH AND INVERSION
HEIGHTS ARE ON THE INCREASE. THOSE INVERSIONS BECOME RATHER
IMPRESSIVE INDEED...WITH POTENTIAL FOR H7 LEVELS TO BE
REALIZED...WITH INTENSE UPWARD OMEGA PEGGED IN THE HEART OF THE
DENDRITIC GROWTH ZONE (THAT WHOLE FLUFF FACTOR THING). SNOW SHOWER
MORPHOLOGY REMAINS THE BIGGEST UNKNOWN...WITH CHANGING WIND FIELDS
AND AN OVERALL LACK OF SHEAR NOTED THROUGH THE DEEP CONVECTIVE
BOUNDARY LAYER. STILL...HAVE TO BELIEVE SOME VERY HEAVY SNOW SHOWERS
ARE POSSIBLE (ONE OR MORE INCHES PER HOUR) IN DIFFUSED BANDING
STRUCTURES. SOOOOOO....WHAT DOES THIS ALL MEAN TO SNOWFALL AMOUNTS
AND HEADLINE POTENTIAL? ANYONE? ANYONE? WELL...GOTTA TAKE AN
EDUCATED GUESS...AND THINK ADVISORY AMOUNTS ARE EASILY ATTAINABLE (3
TO 5 INCHES...LOCALLY MORE) IN THE TRADITIONAL SNOW BELTS OF
OTSEGO/CHARLEVOIX/ANTRIM/AND NORTHERN LEELANAU COUNTIES. WOULD
EXPECT MUCH LESS SNOW SOUTH OF GRAND TRAVERSE BAY...OWNING TO DEEP
LAYER DRYING. TOUGHEST CALL TIP THE MITT INTO NORTHEAST LOWER WHERE
TROUGHING WILL RESIDE. WILL STICK WITH INHERITED 2 TO 3 INCH MENTION
ACROSS THIS AREA FOR NOW...BUT DEFINITELY PASS ALONG CONCERNS FOR
THE POTENTIAL OF MUCH MORE TO THE DAY CREW. PLACEMENT OF SURFACE
TROUGHING AND MAINTENANCE OF EAST/NORTHEAST FLOW DOES NOT BODE WELL
FOR SIGNIFICANT SNOW ACCUMULATIONS NORTH OF THE MIGHT MAC...AND
STARTING TO WONDER IF PARTS OF NORTHEAST CHIPPEWA COUNTY WILL SEE
MUCH ACCUMULATING SNOW AT ALL.

A TOUCH MORE STRAIGHTFORWARD FORECAST HEADING INTO TONIGHT...BUT
STILL PLENTY OF CONCERNS. LAKE AGGREGATE TROUGHING QUICKLY SHUNTS
SOUTH...VEERING WINDS AROUND TO NORTHERLY...FORCING LAKE SNOWS TO
TARGET THE GRAND TRAVERSE BAY REGION AND POINTS SOUTHWEST. STILL
SOME REALLY GOOD SIGNATURES THIS EVENING...WITH 750MB INVERSION
HEIGHTS AND STRONG OMEGA IN THE DGZ. SHIFTING WINDS LIKELY TO
PREVENT GOOD BAND ORGANIZATION...BUT COULD SEE SOME RATHER HEAVY
SNOW SHOWERS CONTINUE TO TARGET PORTIONS OF LEELANAU COUNTY. WILL
HIGHLIGHT THIS FOR AT LEAST A COUPLE MORE INCHES. WINDS LOOK TO BACK
QUICKLY NORTHWESTERLY DURING THE EARLY MORNING MONDAY...BRINGING
SNOW SHOWERS BACK INLAND...ALTHOUGH AT A MUCH LIGHTER INTENSITY WITH
DEPLETING MOISTURE PROFILES AND LOWERING INVERSIONS. LOW
TEMPERATURES TONIGHT VERY TRICKY...AND COMPLETELY BASED OFF CLOUD
TRENDS. SUPPORT FOR CANADIAN PLATEAU LAND BREEZE INFILTRATION INTO
EASTERN UPPER AND THE TIP OF THE MITT RATHER HIGH...SUGGESTING SOME
PAINFULLY COLD TEMPERATURES AS SKIES CLEAR. WILL TREND THESE AREAS
DOWN SEVERAL DEGREES...STOPPING JUST SHORT OF DOUBLE DIGIT NEGATIVE
READINGS FOR NORTHEAST CHIPPEWA COUNTY.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 220 AM EST SUN DEC 15 2013

THE UPPER PATTERN WILL BE A BIT LESS AMPLIFIED EARLY IN THE WORK
WEEK...THOUGH WNW FLOW ALOFT WILL STILL DOMINATE. SHALLOW SHORTWAVE
RIDGING ARRIVES TOWARD MIDDAY MONDAY...BEFORE THE NEXT BIT OF
NORTHERN STREAM ENERGY REACHES SUPERIOR. THE MOST PROMINENT UPPER
TROF WILL BE OVERHEAD ON TUESDAY. AT THE SURFACE...LOW PRESSURE IN
CENTRAL CANADA WILL PUSH A WARM AND COLD FRONT ACROSS THE REGION
MONDAY NIGHT AND TUESDAY RESPECTIVELY. THE WARM FRONT WILL
TEMPORARILY DISPLACE OUR PRESENT POLAR AIRMASS IN FAVOR OF A MILDER
PACIFIC AIRMASS. PRECIP CHANCES AND TEMP TRENDS REMAIN THE MAIN
CONCERNS.

MONDAY...WEAK 1000-850MB NW FLOW WILL BE PRESENT TO START THE
MORNING...ALONG WITH PLENTY OF COLD AIR (850MB TEMPS STILL IN THE
UPPER MINUS TEENS). SO SOME SHSN CAN BE EXPECTED NEAR LAKE MI AND
LAKE SUPERIOR EARLY ON...DESPITE RATHER DRY MID-LEVEL AIR (850-700MB
RH 35-45 PERCENT). ISENTROPIC ASCENT WILL EXTEND INTO THE WEST HALF
OF THE FORECAST AREA AROUND MIDDAY...BY WHICH TIME 1000-850MB WINDS
WILL HAVE STRENGTHENED AND BACKED SW. THAT WILL BE THE BEGINNING OF
A BRIEF PERIOD (3-6HR) OF LAKE ENHANCED SNOW. SAID FORCING LOOKS TO
BE OF MODERATE INTENSITY...THOUGH AWAY FROM LAKE MI MOISTURE
AVAILABILITY IS NOT IDEAL. NEAR IT THOUGH...INVERSION HEIGHTS REMAIN
QUITE DEEP FOR A WARM ADVECTION/SW FLOW EVENT (5-6K FT)...AND THE
MAX VERTICAL VELOCITY IS PEGGED VERY NICELY IN THE DGZ (-13 TO
-15C). AM THUS CONCERNED ABOUT A REASONABLY HEALTHY SW FLOW
EVENT..LIMITED MAINLY BY JUST MODERATE DYNAMICS RATHER THAN THE
SHARP/STRONG FORCING WE SOMETIMES SEE FROM CLIPPERS.

WILL QUICKLY EXPAND POPS EASTWARD WITH TIME...WITH THE MAIN FOCUS
NEAR LAKE MI IN BOTH PENINSULAS...BUT ESPECIALLY IN MACKINAC CO.
WILL HAVE A SNOWFALL MAX NEAR 4 INCHES BETWEEN NAUBINWAY AND ST
IGNACE...1-3 FROM LEELANAU UP TO EMMET...LESS THAN 2 INCHES
ELSEWHERE.

MAX TEMPS IN THE MID TEENS TO LOWER 20S.

MON NIGHT...MILDER/DRIER AIR WILL GRADUALLY INVADE FROM SW TO
NE MONDAY NIGHT. BY 09Z...850MB TEMPS WILL BE IN THE -10 TO -7C
RANGE...ABSOLUTELY BALMY BY RECENT STANDARDS. SOME LAKE ENHANCED
PRECIP WILL LINGER FOR EASTERN UPPER AND FAR NORTHERN LOWER MI IN
THE EVENING...BUT THE INTENSITY WILL WANE BY 03Z AS BETTER
FORCING/MOISTURE EXITS. OVERNIGHT...UPPER TROF SWINGING AROUND THE
BASE OF THE LOW IN FAR NORTHERN ONTARIO WILL ADVANCE ACROSS WI. THAT
WILL RETURN DEEPER MOISTURE AND SOME SPOTTY LIGHT SYNOPTIC SNOW INTO
WESTERN SECTIONS OVERNIGHT (MAINLY TOWARD MORNING)...THOUGH LITTLE
LAKE ASSISTANCE WILL OCCUR GIVEN THE MILDER AIRMASS. MIN TEMPS WILL
BE EARLY IN THE EVENING...IN MOST PLACES VERY CLOSE TO MONDAY MAX
TEMPS...WITH READINGS RISING OVERNIGHT.

TUESDAY...COLD FRONT SWEEPS ACROSS NORTHERN MI IN THE MORNING...WITH
A SECONDARY FRONT DRAPED ACROSS SUPERIOR AT THE END OF THE DAY. COLD
ADVECTION IS WEAK...WITH 850MB TEMPS ONLY LOWERING BACK TOWARD OR A
BIT COOLER THAN -10C. POTENTIAL FOR SOME LIGHT SYNOPTIC SNOW
ASSOCIATED WITH THE COLD FRONT AND INITIAL UPPER TROF...AND PERHAPS
JUST COLD ENOUGH TO REGENERATE LIGHT LAKE EFFECT SNOW IN THE PM.
WILL GENERALLY GO WITH HIGH CHANCE TO LOW LIKELY POPS MOST AREAS
THRU THE DAY. IT WILL BE TOASTY THOUGH...WITH MAX TEMPS IN THE UPPER
20S TO AROUND 30F.

REST OF THE FORECAST...SOME CHANGES FROM 24 HOURS AGO. THE BROADER
PATTERN WILL FINALLY (THOUGH ONLY BRIEFLY) FLIP-FLOP...WITH DIGGING
ENERGY IN THE WEST HELPING TO TURN THE UPPER FLOW MORE ZONAL...AND
EVENTUALLY SW-ERLY BY LATE IN THE WEEK. HOWEVER...THE VORTEX OVER
CENTRAL CANADA IS NOW PROGGED TO BE STRONGER...AND WILL BE QUICKER
TO KNOCK DOWN ANY TENDENCY TOWARD RIDGING IN OUR NECK OF THE WOODS.
THUS...THE LATE-WEEK WARM-UP IS GOING TO BE TEMPERED JUST A
SMIDGE...AND ARCTIC AIR IS LIKELY TO SURGE RIGHT BACK IN TO START
NEXT WEEKEND.

AS FOR POPS/WX...COOLISH POST-FRONTAL AIR WILL SUPPORT LIGHT LAKE
EFFECT INTO WED DOWNSTREAM OF LAKES MI/SUPERIOR. BRIEF LULL WED
NIGHT...BEFORE WARM-ADVECTION RELATED FORCING CRANKS UP SOME MORE
SNOW CHANCES. GIVEN A LESS SUBSTANTIAL DIFFICULT...APPEARS IT WILL
BE DIFFICULT TO SQUEEZE OUT MUCH IN THE WAY OF LIQUID PRECIP. LAKE
EFFECT SNOW WILL RETURN WITH THE COLD AIR ON SATURDAY.
