AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
645 AM EST MON NOV 25 2013
.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 516 AM EST MON NOV 25 2013
WV IMAGERY AND RUC ANALYSIS INDICATED WNW MID/UPPER LEVEL FLOW FROM
CNTRL CANADA THROUGH THE GREAT LAKES WITH ONE SHORTWAVE TROUGH FROM
NW ONTARIO INTO NW MN AND ANOTHER WELL TO THE NORTH MOVING INTO NRN
SASK. AT THE SFC...A TIGHT PRES GRADIENT PREVAILED ACROSS THE WRN
GREAT LAKES BTWN A 1000 MB LOW LOCATED JUST NORTH OF THUNDER BAY
ONTARIO AND A 1036 MB RIDGE OVER THE OH VALLEY. WITH THE STRONGEST
PRES FALLS MOVING TO THE NE OF LAKE SUPERIOR...VERY STRONG SW WINDS
PERSISTED ACROSS WRN LAKE SUPERIOR AND NRN LAKE MICHIGAN. WAA
LEADING TO INCREASING STABILITY HAS LIMITED MIXING OF 45-50 KNOT
925-850 MB WINDS TOWARD THE SFC EXCEPT OVER THE RELATIVELY WARM LAKE
MICHIGAN WATERS. GUSTS IN THE 35-40 KT RANGE PERSISTED FROM FAIRPORT
TO PORT INLAND WHERE A WIND ADVISORY WAS IN EFFECT. WINDS OVER
INLAND LOCATIONS AT ESC AND ISQ WERE ONLY GUSTING TO AROUND 25
KNOTS. RADAR INDICATED WEAK RETURNS...MAINLY OVER THE ERN CWA...WITH
SOME PATCHY LIGHT SNOW OR FLURRIES SUPPORTED BY 700-300 QVECTOR CONV
AND ISENTROPIC LIFT AHEAD OF THE UPSTREAM SHRTWV.
TODAY...EXPECT WINDS TO SUBSIDE BY THE 15Z WIND ADVISORY EXPIRATION
TIME AS THE CORE OF THE STRONGEST 925-850 MB WINDS SHIFTS OFF TO THE
EAST. AS THE AREA OF LIGHT SNOW MOVES TO THE EAST...SOME LAKE
ENHANCEMENT MAY BE POSSIBLE WITH THE SW FLOW OFF OF LAKE MICHIGAN
BUT SHOULD REMAIN MAINLY TO THE SOUTH AND EAST OF THE CWA. OVER THE
KEWEENAW...AN AREA OF LOW LEVEL CONV AS WINDS VEER FROM SW TO W MAY
BRING A BRIEF PERIOD OF LAKE ENHANCED SNOW. HOWEVER...MID LEVEL
DRYING WITH THE DRY SLOT AND MARGINAL INSTABILITY WITH 850 MB TEMPS
AROUND -7C (LAKE SFC NEAR 4C) SUPPORTS ONLY CHANCE POPS WITH ANY
ACCUMULATIONS ONLY AMOUNTING TO A HALF INCH OR LESS. INCREASING
850-700 MB MOISTURE AND AND 850/700 MB TEMPS DROPPING TO -10C/-17C
WITH THE APPROACH OF THE SHRTWV WILL ALSO BRING AN INCREASE IN LAKE
ENHANCED SNOW INTO THE WEST AND THE ERN SHORELINE FROM PICTURED
ROCKS TO GRAND MARAIS.
TONIGHT...STRONGER CAA DROPPING 850 MB TEMPS TO AROUND -18C BOOSTING
LAKE INDUCED CAPES TO NEAR 700 J/KG ALONG WITH STRENGTHENING
CYCLONIC NW FLOW WILL BRING A FURTHER INCREASE IN LES INTO THE WEST.
THE HIGH RES MODELS OFFER A VARIETY OF SOLUTIONS AS TO WHERE THE
HEAVIER SNOW BANDS WILL FOCUS AND DELAY THE STRONGER VEERING WIND
SHIFT AND LOW LEVEL CONV BAND MOVING IN TIL AFT 12Z. ALTHOUGH
SEVERAL INDICATE THE GREATER SNOW POTENTIAL INTO THE KEWEENAW AND
IRONWOOD AREAS...CONFIDENCE IN IN HIGHLIGHTING ANY PARTICULAR
LOCATION IS LIMITED. SO...A GENERAL 2 TO 5 INCH FCST WAS INCLUDED
FOR MOST OF THE NW TO WNW FLOW SNOWBELTS IN THE WEST AS WELL AS
LOCATIONS NORTH OF M-28 EAST OF MUNISING.
.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 437 AM EST MON NOV 25 2013
EXTENT OF LAKE EFFECT SNOW AND SNOW AMOUNTS ALONG WITH THE NEED FOR
ANY ADVISORIES OR WARNINGS TUESDAY/TUESDAY NIGHT IS PRIMARY FOCUS.
IN LARGE SCALE...STRONG SHORTWAVE IN NORTHERN STREAM CURRENTLY OVER
NORTHERN MANTIOBA WILL BE CROSSING UPR MICHIGAN AND LK SUPERIOR ON
TUESDAY. NAM/GFS/ECMWF DECENT AGREEMENT WITH TIMING OF LARGER SCALE
IMPACTS AS THEY ALL SHOW H7-H5/H5-H3 Q-VECTOR CONVERGENCE INTO WESTERN
UPR MICHIGAN BEFORE 12Z TUESDAY SPREADING TO CNTRL CWA BY 18Z AND
EXITING EASTERN CWA BY 00Z WEDNESDAY. MAY SEE MINOR LGT SNOW EVEN
INTO SOUTH AS THE SHORTWAVE CROSSES THE REGION. BIGGEST IMPACT
THOUGH WILL BE ON LK EFFECT THAT BEGINS LATE TONIGHT. NAM AND GFS
FORECAST SOUNDINGS SHOW GOOD RESPONSE FM THE WAVE WITH INVERSION
HEIGHTS RISING ABOVE 5KFT LATE TONIGHT AND SPIKING UP TO 8-10KFT BY
MIDDAY TUESDAY. LAKE EQUILIBRIUM LEVELS INCREASE TO 13KFT AND LAKE
INDUCED CAPE VALUES CLIMB OVER 700J/KG AS H85 TEMPS FALL TO -17C TO
-20C BY TUESDAY NIGHT. SOUNDINGS ALSO INDICATE INCREASING MOISTURE
QUALITY TUESDAY INTO MOST OF TUESDAY NIGHT. SO...INSTABILITY AND
MOISTURE NOT THE ISSUE FOR MODERATE TO HEAVY SNOW. BOTH PARAMETERS
ARE THERE NO DOUBT. MAIN STICKING POINT FOR THE FORECAST ARE
LOW-LEVEL WIND FIELDS AND MORE SPECIFICALLY THE WIND DIRECTION WHICH
IS ALL SO CRITICAL FOR PEGGING WHERE HEAVIEST LK EFFECT WILL OCCUR.
UNFORTUNATELY...NOTEABLE DIFFERENCES EXIST BTWN THE NAM/NCEP HIGH
RES RUNS AND THE COARSER ECMWF/GFS AND ALSO THE GEM. MAIN ISSUE IS
HOW QUICKLY SOUTH TO BRING LOW-LEVEL WIND SHIFT PASSAGE ON TUESDAY.
PASSAGE OF THE TROUGH ESSENTIALLY KICKS LK EFFECT FM WNW/NW FLOW
AREAS TO AREAS FAVORED BY N/NNE WINDS. USUALLY LIKE THE NAM WITH
HIGHER RESOLUTION DETAILS...BUT SUCH A QUICK TROUGH PASSAGE AT
15Z-18Z ON TUESDAY IN THE NORTH SEEMS QUESTIONABLE AS SHORTWAVE
TROUGH AXIS IS STILL OVER CNTRL UPR MICHIGAN AT 18Z. WOULD EXPECT
THE TROUGH PASSAGE TO OCCUR TUESDAY EVENING IN THE WAKE OF THE
SHORTWAVE TROUGH CROSSING THE AREA. OVERALL...PREFERRED SOLUTION
IS PROBABLY MOST CLOSEST TO GFS/LOCAL REGIONAL WRF AND ECMWF.
WHAT THIS MEANS IN TERMS OF LK EFFECT SNOW IS EXPECT A PROLONGED
PERIOD OF LK EFFECT FOR WNW/NW FLOW AREAS LATE TONIGHT THROUGH LATE
TUESDAY AFTN /WHITE PINE TO ROCKLAND/TWIN LAKES AND MAYBE AS FAR
NORTH AS HOUGHTON/ AND ALSO OVER NORTHERN PARTS OF ALGER AND LUCE
COUNTIES. HEAVIER LK EFFECT THEN SHIFTS TO GOGEBIC/WESTERN ONTONAGON
AND MARQUETTE COUNTIES BY TUESDAY EVENING. BASED ON EXPECTED SLR/S
NEARING 20:1 OR EVEN ABOVE 20:1 AND QPF WHICH WAS BLEND OF REGIONAL
WRF AND EVENTUALLY THE WETTER NAM DNG LATER TUESDAY...SEEMS LIKE A
SOLID ADVY EVENT IS IN STORE WITH SNOW AMOUNTS OF 4-6/5-8 INCHES IN
THE 12 HOUR PERIOD FOR TUESDAY AND AGAIN ON TUESDAY NIGHT...THOUGH
THE LOCATIONS OF HEAVIEST SNOW SHOULD SHIFT AROUND AS WINDS IN THE
LAKE CONVECTIVE LAYER SO SOME SHEAR AND DO NOT STAY LOCKED IN THE
SAME DIRECTION FOR VERY LONG PERIOD OF TIME. SOME LOCATIONS IN THE
FAR WESTERN CWA /VCNTY OF IWD TO BERGLAND AND WHITE PINE/ MAY COME
CLOSER TO WARNING CRITERIA TUESDAY AFTN INTO TUESDAY NIGHT BUT SINCE
THE LARGER SCALE FORCING IS DIMINISHING WHEN WIND DIRECTION BECOMES
A MORE FAVORABLE N-NNE TO INCREASE CONVERGENCE IN THESE AREAS...WILL
OPT TO ISSUE THE ADVY AND LET FUTURE SHIFTS UPGRADE TO WARNING IF IT
IS NEEDED. SNOW WILL BE THE MAIN ISSUE WITH THIS EVENT. WINDS WILL
BE GUSTY 25-35 MPH...BUT STRONGEST WINDS AND BLSN/VSBY IMPACTS WILL
BE MORE OVER THE NORTHERN PARTS OF THE KEWEENAW ON TUESDAY AND
PERHAPS INTO NCNTRL UPR MICHIGAN ON TUESDAY NIGHT. NOT EXPECTING
WIDESPREAD BLSN AS THE EVENT THIS LAST WEEKEND HAD.
FOR NOW...COORDINATED WITH SHORT TERM FORECASTER AND PUT OUT LAKE
EFFECT SNOW ADVISORIES FOR WESTERN TIER. ADDITIONAL HEADLINES WILL
LIKELY BE ISSUED OVER NCNTRL AND POSSIBLY NORTHEAST CWA LATER TODAY
OR TONIGHT...BUT SINCE THE MORE SIGNIFICANT SNOW WILL NOT OCCUR IN
THESE AREAS UNTIL LATER TUESDAY OR EVEN AS LATE AS TUESDAY NIGHT IF
GFS IS COMPLETELY CORRECT...WILL NOT ISSUE THOSE HEADLINES NOW. NOT
ENOUGH CONFIDENCE THAT THESE AREAS WOULD SEE WARNING AMOUNTS SO DID
NOT WANT TO PUT A WATCH OUT EITHER.
SNOW SHOWERS PERSIST FOR N FLOW AREAS ON WEDNESDAY...BUT INTENSITY
WILL BE ON THE WANE WITH LOWERING INVERSION HEIGHTS TO AT OR BLO
5KFT. EVEN AS SNOW DIMINISHES...THE DGZ WILL BE IN THE HEART OF THE
LAKE CONVECTIVE LAYER SO WHAT SNOW SHOWERS ARE LEFTOVER ON WEDNESDAY
WILL BE THE EFFECIENT FLUFFY TYPE. WINDS WILL BE ON THE DECREASE AS
WELL...AS WILL BLSN/ASSOCIATED VSBY ISSUES. SINCE THE FLOW REMAINS
LGT NORTH ALL DAY AND INSTABILITY IS MORE THAN SUFFICIENT...SNOW
SHOWERS PROBABLY WILL NOT END COMPLETELY FOR FAR WEST OR NCNTRL BUT
THEY MAY BECOME PINNED CLOSER TO THE SHORELINES ON WEDNESDAY NIGHT
AS MESOSCALE EFFECTS/LAND BREEZES START TO DRIVE THE LOW-LEVEL
CONVERGENCE.
STILL COULD SEE SOME LGT SNOW ON THANKSGIVING. NO BIG IMPACT TO
TRAVEL EXPECTED THOUGH. BEST CHANCE OVER THE NORTHERN TIER. WEAK
TROUGH WORKS THROUGH THURSDAY NIGHT INTO FRIDAY. COULD SEE SOME SNOW
SHOWERS ACROSS KEWEENAW IN WNW FLOW ON FRIDAY. WEEKEND WILL FEATURE
MODEST WARMING TREND WITH SOME AREAS SLIGHTLY ABOVE FREEZING FOR
DAYTIME HIGHS. LGT SNOW MAY ACCOMPANY THIS WARM AIR ADVECTION BUT
LOOKS LIKE BETTER CHANCE FOR ANY SNOW ACCUMULATION WILL REMAIN TO
NORTH OF CWA.
