AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
549 AM EST SAT JAN 1 2011
.SYNOPSIS...
WATER VAPOR IMAGERY AND RUC ANALYSIS SHOW A TROF FROM THE ROCKIES
INTO THE PLAINS. WITHIN THE TROF...A CLOSED MIDLEVEL LOW WAS LIFTING
NNE INTO MN. 00Z RAOBS SHOWED IMPRESSIVE 12HR 500MB HEIGHT FALLS
UPWARDS OF 220M AT KOAX. DESPITE OVERALL IMPRESSIVE LOOK ON WATER
VAPOR IMAGERY AND STRONG DYNAMICS...PCPN IS SURPRISINGLY LIMITED
AROUND THE MIDLEVEL LOW. MIDLEVEL DRY PUNCH UNDER UPPER JET
SUPPORTING SYSTEM IS SURGING INTO THE UPPER LAKES EARLY THIS
MORNING. AT THE SFC...LOW PRES IS OVER WRN LAKE SUPERIOR TO THE N OF
THE APOSTLE ISLANDS WITH COLD/OCCLUDED FRONT BOWING ACROSS UPPER MI.
&&
.DISCUSSION...
WITH LIQUID PCPN ISSUES ENDING IN THE NEXT COUPLE OF HRS WITH CAA
QUICKLY SPREADING INTO UPPER MI...ATTENTION FOR THIS FCST WILL TURN
TO LES/WINDS AND TEMPS.
DEEPENING MIDLEVEL LOW WILL TRACK ACROSS FAR WRN LAKE SUPERIOR/NE MN
TOWARD LAKE NIPIGON TODAY. ON THE SE SIDE OF CIRCULATION...
OCCASIONAL FLURRIES/-SHSN SHOULD OCCUR OVER MAINLY WRN UPPER MI
TODAY IN CLOSER PROXIMITY TO MIDLEVEL SYSTEM. SINCE LOW-LEVEL FLOW
IS SWRLY...LAKE ENHANCED SNOW WILL LIKELY REMAIN OFFSHORE OF THE
KEWEENAW FOR THE BULK OF THE DAY. IF WINDS DO MAINTAIN ENOUGH SRLY
COMPONENT THRU THE DAY...SNOW AMOUNTS OVER THE W WILL BE LIGHT...
PROBABLY NOT MORE THAN AROUND 1 INCH. SNOW MAY BEGIN TO PICK UP LATE
IN THE DAY AS WINDS BEGIN TO VEER. SW FLOW MAY BRING SOME LES INTO
THE FAR ERN FCST AREA OFF LAKE MICHIGAN TODAY...BUT LATEST MODEL
GUIDANCE AGREES THAT LOW-LEVEL FLOW IN THAT AREA WILL HAVE A LITTLE
TOO MUCH OF A WRLY COMPONENT FOR LES TO BE MUCH OF AN ISSUE. MORE
SIGNIFICANT LES WILL STAY SAFELY E OF KISQ/KERY. ALTHOUGH STRONG
850MB CAA IN THE MORNING WILL BECOME NEUTRAL IN THE AFTN...SFC TEMPS
WILL FALL MOST AREAS THRU THE ENTIRE DAY. UPPER SINGLE DIGIT READINGS
APPEAR LIKELY FAR W TOWARD KIWD IN THE AFTN WHILE TEMPS FALL TO
AROUND 20F E. WITH WINDS AT THE TOP OF THE MIXED LAYER PROGGED AROUND
40KT TODAY...GUSTS MAY BRIEFLY FLIRT WITH ADVY CRITERIA OF 45MPH. NOT
EXPECTING WIDESPREAD OR PERSISTENT CRITERIA TO BE REACHED...SO ADVY
DOES NOT APPEAR NEEDED ATTM. ONE AREA THAT WILL NEED TO BE WATCHED
MORE CLOSELY TODAY IS FROM JUST E OF KESC TO KISQ AND POSSIBLY TO
KERY AS SW FLOW OVER WARMER LAKE WATERS WILL ENSURE MORE EFFICIENT
MIXING.
TURNING TO MAIN LES CONCERN...THE KEWEENAW WILL LIKELY SEE A PERIOD
OF MDT/HVY LES THIS EVENING AS WINDS SHIFT W. THIS HEAVIER SNOW MAY
CLIP NRN ONTONAGON COUNTY AS WELL. MODELS CONTINUE TO INDICATE A
RELATIVELY SHARP WIND SHIFT TO ENHANCE THE POTENTIAL FOR A PERIOD OF
HVY LES BEFORE A MORE MDT LES SETS UP. SOUNDINGS SHOW FAVORABLE
DENDRITIC SNOW GROWTH TEMPS SOLIDLY IN THE CONVECTIVE LAYER TO BOOST
ACCUMULATIONS. CONSIDERING 35-40KT WINDS IN THE MIXED LAYER...ADVY IS
WARRANTED FOR COMBO OF SNOW/BLSN. ACCUMULATIONS OF 4 TO POSSIBLY AS
MUCH AS 8 INCHES IN ISOLATED SPOTS SEEM LIKELY TONIGHT. CONTEMPLATED
GOING WITH A WARNING AS PERSISTENT/WIDESPREAD BLSN COMBINED WITH
PERIODS OF MDT SNOW MAY PUT VIS AOB 1/4SM FREQUENTLY ONCE ENOUGH NEW
FRESH SNOW ACCUMULATION HAS OCCURRED. FOR NOW...WILL OPT FOR
ADVY...BUT POSSIBLE UPGRADE TO WARNING WILL NEED TO BE RECONSIDERED
DURING THE DAY TODAY...ESPECIALLY IN LIGHT OF THE NAM WHICH INDICATES
A MORE SUSTAINED RELATIVELY STATIONARY BAND OF CONVERGENCE SETTING
UP ACROSS THE KEWEENAW TO THE N OF HOUGHTON THRU THE NIGHT INTO SUN
MORNING. IF THAT OCCURS...WARNING WILL LIKELY BE NEEDED. OTHER THAN
THE LES OVER NW UPPER MI...REST OF THE FCST AREA WILL BE MAINLY DRY
AND COLD. WILL BUFFER THE HEAVIER SNOW OVER THE NW FCST AREA WITH LOW
POPS FOR -SHSN...AND TO THE E...WINDS MAY VEER JUST ENOUGH TO BRUSH
LES ALONG THE SHORELINE AREAS FROM GRAND MARAIS EASTWARD. WIND CHILLS
SHOULD PLUMMET TO AROUND -20F IN SOME INTERIOR W AND CNTRL
LOCATIONS TONIGHT...NOT QUITE TO -25F ADVY THRESHOLD.
WITH WRLY FLOW PERSISTING SUN...LES WILL CONTINUE MAINLY OVER THE NW
FCST AREA AND POSSIBLY CLOSE THE SHORE FROM AROUND GRAND MARAIS
EASTWARD. NAM AND ESPECIALLY GFS CONTINUE TO INDICATE CONVERGENCE
INTO THE KEWEENAW BTWN WSW FLOW TOWARD THE APOSTLE ISLANDS AND WNW
FLOW OVER THE NRN PORTION OF LAKE SUPERIOR. THIS SHOULD MAINTAIN
FAIRLY HEALTHY LES ON THE KEWEENAW SUN.
SUN NIGHT...CURRENT MID/UPPER LOW AFFECTING THE UPPER LAKES WILL BE
SETTING UP SHOP OVER HUDSON BAY WITH BROAD CIRCULATION ENCOMPASSING A
GOOD PORTION OF THE NRN CONUS. NEXT SHORTWAVE OF CONCERN WILL BE
DROPPING S THRU SASKATCHEWAN TOWARD THE NRN PLAINS ON W AND SW SIDE
OF BROAD UPPER LOW CIRCULATION. IN RESPONSE...LOW-LEVEL WINDS MAY
BEGIN TO BACK ALREADY SUN NIGHT. AS MORE OF A SRLY COMPONENT TO WIND
DEVELOPS...LES WILL SHIFT N...AFFECTING LESS OF NW UPPER MI. TO THE
E...IF ANY LES IS OCCURRING NEAR THE SHORE E OF MUNISING...IT WILL
GRADUALLY SHIFT OFFSHORE OVERNIGHT. DIMINISHING WINDS AND PARTLY
CLOUDY SKIES SHOULD SET THE STAGE FOR A COLD NIGHT AWAY FROM LAKE
SUPERIOR MODERATION. INCLUDED SINGLE DIGITS BELOW ZERO IN THE
INTERIOR W...BUT IT COULD BE QUITE A BIT COLDER IF IT IS CLEAR MOST
OF THE NIGHT.
WITH THE AFOREMENTIONED SHORTWAVE...MODELS OVERALL ARE TRENDING
SHARPER WITH THIS SYSTEM AS IT ROTATES THRU THE WRN GREAT LAKES TUE
MORNING. IF THIS IS A TREND THAT CONTINUES...WOULD EXPECT A DECENT
SFC LOW TO SPIN UP (PROBABLY OVER LAKE SUPERIOR) AS FORCING
OVERSPREADS THE WARMER WATERS OF THE GREAT LAKES (850MB TEMPS WILL
STILL BE IN THE -12 TO -14C RANGE OVER LAKE SUPERIOR MON INTO MON
NIGHT). COULD BE AN INTERESTING LITTLE SYSTEM FROM AN LES STANDPOINT
AS SOME HVY SNOW CERTAINLY COULD OCCUR. WIND SHOULD BE S TO SW
ACROSS THE FCST AREA MON AHEAD OF SHORTWAVE...SO LAKE SUPERIOR LES
WILL END. HOWEVER...THE SRLY FLOW COMBINED WITH FORCING
OVERSPREADING THE AREA MON AFTN WILL RAISE POSSIBILITY OF LAKE
ENHANCED SNOW OFF LAKE MICHIGAN INTO THE ERN FCST AREA.
ELSEWHERE...WILL INTRODUCE CHC POPS FOR -SN AS FORCING ASSOCIATED
WITH SHORTWAVE ARRIVES. DEPENDING ON STRENGTH/POSITION OF ANY SFC
LOW TRACKING THRU THE UPPER LAKES...THERE COULD BE A PERIOD DECENT
LAKE ENHANCED SNOW TRANSITIONING TO PURE LES OFF LAKE SUPERIOR MON
NIGHT INTO TUE AS WINDS SHIFT NW.
