AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
644 AM EST WED NOV 19 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 426 AM EST WED NOV 19 2014

BROAD UPPER TROUGH OVER MUCH OF THE CENTRAL AND EASTERN CONUS WILL
START TO SHIFT EAST THROUGH THE SHORT TERM PERIOD. ON THE WEST SIDE
OF THIS UPPER TROUGH...A COUPLE SHORTWAVES ARE DIVING SOUTHEAST
TOWARDS THE AREA...ONE IS JUST STARTING TO MOVE INTO NORTHWEST
WISCONSIN AND THE OTHER ONE IS LOCATED NEAR LAKE WINNIPEG. THE
FIRST AND WEAKER SHORTWAVE WILL SLIDE ACROSS SOUTHERN UPPER
MICHIGAN THIS MORNING WHILE THE SECOND SHORTWAVE DROPS ACROSS THE
UPPER GREAT LAKES REGION THIS AFTERNOON/EVENING. AS THE FIRST
SHORTWAVE MOVES THROUGH IT WILL DRAG THE ELONGATED 1007MB SURFACE
TROUGH EAST (CURRENTLY STRETCHING NORTH-SOUTH ACROSS EASTERN
MINNESOTA) INTO WESTERN UPPER MICHIGAN AND WISCONSIN THIS
MORNING AND CONTINUING EASTWARD INTO EASTERN UPPER MICHIGAN THIS
AFTERNOON. AS IT MOVES INTO EASTERN UPPER MICHIGAN...THE SECOND
SHORTWAVE WILL REACH THE FEATURE...STRENGTHENING AND CLOSING OFF THE
TROUGH NEAR THE SOO AT 00Z THURSDAY AT 1000MB AND THEN INTENSIFY
FURTHER TO 997MB AS IT MOVES EAST THROUGH CANADA TONIGHT. WILL TOUCH
ON THE SYNOPTIC SCALE PRECIPITATION FEATURES FIRST...THEN DIVE INTO
LAKE EFFECT PRECIPITATION.

FOR THE SYNOPTIC PRECIPITATION...EXPECT THE BROAD AREA OF LIGHT
SNOW (2.5-5MI VISIBILITIES OVER EASTERN MINNESOTA AND WESTERN
WISCONSIN) AHEAD OF THE SURFACE TROUGH AND ALSO TIED TO THE
SHORTWAVE TO SHIFT EAST INTO UPPER MICHIGAN TODAY. HAVE ALREADY
SEEN THIS SNOW WORKING INTO IRONWOOD OVER THE LAST HOUR. THIS
PRECIPITATION IS TIED TO THE BROAD MID LEVEL Q-VECTOR CONVERGENCE
AND WARM AIR ADVECTION EARLY THIS MORNING...WITH THE BEST FORCING
SLIDING SOUTH OF THE AREA THROUGH WISCONSIN AND INTO LOWER MICHIGAN
THIS MORNING. BUT STILL THINK THERE WILL BE ENOUGH FORCING FROM THE
SURFACE-700MB TROUGH SWEEPING THROUGH THE CWA TO PRODUCE LIGHT SNOW
ACROSS MUCH OF THE AREA BY EARLY AFTERNOON. THE NON LAKE EFFECT
INFLUENCED AREAS WILL GENERALLY SEE 0.02-0.05 OF LIQUID
TODAY...HIGHEST OVER THE SOUTH. WITH SNOW RATIOS ON AVERAGE AROUND
15-1...WOULD EXPECT A BROAD HALF INCH TO MAYBE A TOUCH MORE IN
THOSE AREAS. THIS PRECIPITATION WILL SHIFT EAST AND OUT OF THE AREA
IN THE AFTERNOON...AS THAT LOW LEVEL TROUGH PUSHES THROUGH. THAT
WILL LEAD TO ANOTHER PERIOD OF NORTHWEST WIND LAKE EFFECT BEHIND
THE TROUGH AND DEVELOPING LOW...WITH A BRIEF PERIOD OF LAKE EFFECT
OVER THE EAST AHEAD OF IT.

FIRST FOR THE LAKE EFFECT OFF LAKE MICHIGAN. THIS PART OF THE
FORECAST IS VERY TRICKY...AS THERE ARE STILL SEVERAL SOLUTIONS IN
PLAY FOR TODAY AS THE LOW LEVEL TROUGH MOVES THROUGH. WHILE THIS
OCCURS...EXPECT THE LOW LEVEL WINDS TO GRADUALLY BACK AND
MOISTENING TO OCCUR LATE THIS MORNING AND EARLY AFTERNOON. THIS
WILL DEVELOP A LAKE EFFECT BAND ON LAKE MICHIGAN IN THE SOUTHWEST TO
SOUTH-SOUTHWEST FLOW RIGHT AS THE SECOND SHORTWAVE IS DIVING INTO
THE AREA AND THE SURFACE TROUGH IS OVER CENTRAL UPPER MICHIGAN.
THUS...WILL BE GETTING THE LIGHT SYNOPTIC PRECIPITATION ENHANCED BY
THE LAKE MICHIGAN LAKE EFFECT. THE TRICKY PART ARRIVES IN THE
POTENTIAL FOR A MESO LOW DEVELOPING OVER NORTHERN LAKE MICHIGAN AS
THIS LAKE EFFECT BAND TAKES SHAPE AS THE SURFACE TROUGH AND
SHORTWAVE MOVE THROUGH. THERE SEEMS TO BE A SPLIT IN THE HIGH
RESOLUTION MODELS ON THE LOCATION OF THE DEVELOPMENT OF THE MESOLOW.
THE 00Z NAM/RAP/GEM-REG ALL DEVELOP THE LOW FARTHER TO THE WEST AND
NEAR THE NORTHERN LAKE MICHIGAN BUOY AT 18Z AND SHIFT IT NORTH INTO
SCHOOLCRAFT/LUCE COUNTIES THIS AFTERNOON. MEANWHILE...THE 00Z NCEP
WRF NMM/ARW KEEP THE LOW FARTHER TO THE EAST AND MUCH OF THE LAKE
EFFECT PRECIP OVER FAR SOUTHEAST LUCE COUNTY AND WESTERN
CHIPPEWA/MACKINAC COUNTIES. THE 00Z GFS APPEARS TO BE CLOSER TO THE
NCEP WRF/S WHILE THE 00Z GFS PARALLEL AND NAMDNG ARE A MIDDLE GROUND
BETWEEN THE WEST AND THE EAST SOLUTIONS. FEEL THAT FOLLOWING THE
MIDDLE GROUND IS THE WAY TO GO AT THIS POINT...WITH THE AXIS OF
HEAVIEST PRECIP BRUSHING EASTERN SCHOOLCRAFT AND GENERALLY AFFECTING
WESTERN MACKINAC AND LUCE COUNTIES. EXPECT THE PRECIPITATION TO
START SHORTLY AFTER 18Z AND THEN CONTINUE INTO THE EARLY EVENING
BEFORE WINDS SHIFT TO THE NORTHWEST BEHIND THE DEVELOPING LARGE
SCALE LOW. WITH MUCH OF THE LAKE INDUCED FORCING WITHIN THE DGZ AND
EQUILIBRIUM LEVELS RISING TOWARD 13KFT...SNOW RATIOS WILL BE IN THE
20-30 TO ONE RANGE AND THERE WILL BE THE POTENTIAL FOR MODERATE TO
EVEN HEAVY SNOW WHERE THAT BAND SETS UP. GOING FORECAST HAS 3 TO 5
INCHES AND MAYBE A LOCALIZED 6 ALONG THE LUCE/MACKINAC COUNTY
BORDER FOR THIS AFTERNOON THROUGH EARLY EVENING...WHICH WOULD LINE
UP WITH AN ADVISORY. BUT THE LAKE EFFECT OFF LAKE SUPERIOR
COMPLICATES MATTERS (AND IS ADDRESSED BELOW). FOR
SCHOOLCRAFT...WILL ISSUE A SPS TO HIGHLIGHT THE UNCERTAINTY OF THE
HEAVIEST SNOW AND ALSO TO SHOW 1-3 INCHES OF ACCUMULATION THROUGH
THIS EVENING.

ATTENTION THEN TURNS TO THE LAKE EFFECT BEHIND THE TROUGH OR
DEVELOPING SURFACE LOW WITH INCREASING NORTHWEST TO OCCASIONAL
WEST-NORTHWEST WINDS. OVERALL...THE SETUP LOOKS TO BE FAIRLY
SIMILAR TO THE LAST LAKE EFFECT EVENT...WITH 850MB TEMPS FALLING
INTO THE -16 TO -18C RANGE TONIGHT AND ALLOWING LAKE INDUCED
EQUILIBRIUM LEVELS TO RISE TO AROUND 15KFT OVER THE WEST THIS
EVENING AND THEN TO NEAR 18KFT OVER THE EAST OVERNIGHT. IN
GENERAL...LOOKS LIKE SNOW RATIOS FROM THE LAST EVENT WERE AROUND 20
TO 1 AND THAT SEEMS REASONABLE WITH THE ADDITION OF SOME COLUMNS TO
THE SNOW ABOVE THE DGZ...ALTHOUGH THE SLIGHTLY LIGHTER WINDS COULD
LEAD TO VALUES BEING CLOSER TO THE MID 20S. WILL SHOW A QUICK
INCREASE TO THE LAKE EFFECT THIS AFTERNOON OVER THE WEST...WITH THE
INCREASED CONVERGENCE AS THE LOW LEVEL SURFACE TROUGH SWEEPS THROUGH
AND PUSHES THE EXISTING SOUTHWESTERLY LAKE EFFECT INLAND. WOULD
EXPECT A VERY QUICK SEVERAL INCHES OF ACCUMULATIONS THROUGH EARLY
EVENING BEFORE A MORE STEADY LIGHT TO MODERATE WIND PARALLEL LAKE
EFFECT BECOMES ESTABLISHED BY LATE EVENING AND REMAINS THROUGH THE
NIGHT. WILL NEED TO WATCH SOUTHWEST ONTONAGON AND GOGEBIC COUNTIES
AS THERE CONTINUES TO BE HINTS OF THE NEAR SURFACE FLOW BACKING
SLIGHTLY THROUGH THE NIGHT AND AIDING CONVERGENCE AND PRODUCING A
STRONGER BAND IN THAT AREA. WILL SHOW SOME SLIGHTLY HIGHER AMOUNTS
TO ACCOUNT FOR THAT. FORECAST SNOWFALL AMOUNTS OVER THE WEST FOR
THIS AFTERNOON THROUGH TONIGHT ARE IN THE 5 TO 10 INCH RANGE. THIS
IS A SOLID ADVISORY (ESPECIALLY WITH SOME BLOWING SNOW NEAR LAKE
SUPERIOR) AND WILL ISSUE ONE FOR GOGEBIC THROUGH THE KEWEENAW
STARTING THIS AFTERNOON AND CONTINUING THROUGH THURSDAY. WITH THE
WINDS IN THE 20-30KT RANGE...EXPECT THE LAKE EFFECT TO MAKE IN
FARTHER INLAND AND SPREAD THE HIGHER AMOUNTS INTO SOUTHERN HOUGHTON
AND BARAGA COUNTIES (AND COULD EVEN AFFECT FAR NORTHWESTERN
MARQUETTE COUNTY). THUS...WILL ALSO INCLUDE THEM IN THE LES
ADVISORY. AS THE TROUGH PUSHES EAST THROUGH THE EVENING
HOURS...EXPECT THE NORTHWEST TO WEST-NORTHWEST LAKE EFFECT TO KICK
IN OVER THE EAST AROUND MIDNIGHT. SHOULD SEE AN INITIAL STRONG
CONVERGENCE BAND PUSH ON SHORE DURING THAT TIME THEN THE WIND
PARALLEL LES THROUGH THE REST OF THE NIGHT. WITH THE LINGERING
SURFACE TROUGH OVER THE EASTERN LAKE...IT DOES APPEAR THAT THERE
WILL BE A DOMINATE BAND OVER EASTERN ALGER...NORTHERN SCHOOLCRAFT
AND NORTHWEST LUCE COUNTY OVERNIGHT AND THAT WILL HELP BOOST
SNOWFALL TOTALS. OVERALL FOR TONIGHT...HAVE AMOUNTS OF 4 TO 8
INCHES TO THE EAST OF MUNISING. AFTER COORDINATION WITH THE LONG
TERM SHIFT...WILL GO AHEAD AND ISSUE A LES WARNING FOR THE COMBINED
TONIGHT THROUGH THURSDAY NIGHT PERIOD. FOR LUCE...OPTED TO START IT
EARLIER (18Z) TO CAPTURE THE INITIAL LAKE ENHANCED SNOWFALL THIS
AFTERNOON AND EARLY EVENING...WHICH WILL KEEP THE HEADLINES SIMPLE
AND WITHOUT DOUBLE HEADLINES. WILL MAKE SURE TO HIGHLIGHT THE TWO
WAVES OF SNOW...WITH THE WORST CONDITIONS OVER THE NORTH LATE
TONIGHT INTO THURSDAY MORNING FOR LUCE COUNTY.

.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 442 AM EST WED NOV 19 2014

MAIN FCST CONCERNS IN THE LONG TERM ARE ONGOING LES ON THU INTO
EARLY FRI WITHIN THE COLD...CYC NW FLOW LEFT IN THE WAKE OF
DEPARTING LO PRES IN QUEBEC. FOCUS FOR THE WEEKEND WL TURN TO
WARMING TEMPS AND THE POTENTIAL FOR SOME MIXED PCPN SAT/SUN AS A LO
PRES IN THE PLAINS MOVES NNE AND NEAR UPR MI. COLDER AIR AND SOME
LES ARE LIKELY TO RETURN EARLY NEXT WEEK BEHIND THIS LO.

THU...STRONG SHRTWV OVER THE UPR LKS AND ACCOMANYING SFC LO PRES
OVER FAR SW QUEBEC ON THU MRNG ARE FCST TO SHIFT STEADILY TO THE E.
LINGERING DEEP LYR QVECTOR CNVGC OVER THE E ON THU MRNG IS FCST TO
EXIT BY 18Z AND GIVE WAY TO SOME DEEP LYR QVECTOR DVGC UNDER RISING
H5 HGTS UP TO 100-120M IN THE 12Z THU-00Z FRI PERIOD. DESPITE THE
ONSET OF THE NEGATIVE DYNAMICS THAT ARE FCST TO LOWER INVRN BASE W-E
THRU THE DAY...SHARP CYC NW FLOW IN THE PRESENCE OF H85 TEMPS
FALLING TO S LO AS ABOUT -21C WITHIN THE THERMAL TROF MOVING ACRS
THE UPR LKS WL BE FAVORABLE FOR MODERATE TO HEAVY LES. THIS PCPN
SHOULD BE HEAVIEST IN THE MRNG OVER THE E HALF WITH ARRIVAL OF THE
TROF AXIS/SHARP LLVL CNVGC WHILE ABUNDANT MSTR TO H5 IS STILL
PRESENT AND FCST SDNGS SHOW DEEP INSTABILITY WITH EQUILIBRIUM LVL AS
HI AS H55 OR SO. FAVORABLE SN GROWTH RELATED TO SHARP UVV FCST
WITHIN DGZ FM ABOUT 3-6K FT MSL AND A POSSIBLE LK NIPIGON CONNECTION
WL ALSO ENHANCE SN TOTALS. GUSTY NW WINDS WL ALSO RESULT IN
CONSIDERABLE BLSN. ALTHOUGH THE DYNAMIC FORCING WL BE GONE BY 12Z
OVER THE W AND FCST SDNGS SHOW THE ONSET OF MID LVL
DRYING...LINGERING CYC NW FLOW ESPECIALLY IN THE MRNG WL ALLOW FOR
AT SOME MODERATE TO HEAVY LES. BUT AS THE SUBSIDENCE INVRN
STRENGTHENS AND SINKS TOWARD H85 IN THE AFTN... THERE SHOULD BE A
DIMINISHING TREND IN THE SN IN THOSE AREAS. THE BEST CHC FOR DRY WX
WL BE IN THE DOWNSLOPE AREAS OF THE SCENTRAL DURING THE AFTN
FOLLOWING THE EXIT OF THE DEEPER MSTR. HI TEMPS WL RUN WELL BLO
NORMAL AGAIN UNDER THE ARRIVING H85 THERMAL TROF AND MAY SET MORE
DAILY RECORD LO MAX TEMP RECORDS.

THU NGT...SFC HI PRES RDG MOVING E UNDER THE RISING HGTS IS FCST TO
MOVE INTO WI BY 12Z FRI...RESULTING IN A BACKING/MORE ACYC FLOW
ESPECIALLY OVER THE W. THESE BACKING WINDS...ENHANCED BY SFC LAND
BREEZE FLOW...SHOULD ALLOW THE LES OVER THE W TO SHIFT AWAY FM
IRONWOOD AND INTO THE KEWEENAW THRU THE NGT. WHILE THE MORE SLOWLY
BACKING H925 FLOW MAY LIMIT THE RESIDENCE TIME OF THE BANDS OVER THE
E...SOME OF THE MODELS ARE SHOWING A REINFORCING SHRTWV DIGGING SEWD
JUST TO THE NE OF LK SUP. ALTHOUGH THE DPVA/DYNAMIC FORCING IS
PROGGED TO STAY TO THE NE OF UPR MI...A SLOWING OF THE BACKING WIND
TREND ASSOCIATED WITH THIS SHRTWV PASSAGE IN CONCERT WITH INCRSG
LAND BREEZE CNVGC MAY RESULT IN CONTINUED HEAVY LES...ESPECIALLY
NEAR LK SUP E OF GRAND MARAIS. OVER THE INTERIOR W AND SCENTRAL...
EXPECT A VERY CHILLY NGT WITH SOME BLO ZERO MINS WITH PWAT AS LO AS
0.10 INCH. STEADY WNW H925 WINDS UP TO 20 KTS MAY LIMIT THE DIURNAL
TEMP DROP A BIT.

FRI...AS THE UPR TROF OVER ERN CANADA DRIFTS TO THE E...THE FLOW
ALOFT WL TREND MORE ZONAL IN ADVANCE OF AN INCOMING SHRTWV RDG THAT
WL BRING ABOUT 12HR H5 HGT RISES UP TO 150-200M. DESPITE THESE HGT
RISES...DVLPG ISENTROPIC ASCENT IN THE SW FLOW TO THE NW OF SFC HI
PRES MOVING TOWARD THE MID ATLANTIC STATES WL BRING ABOUT INCRSG
MID/HI CLDS. LINGERING LES  OVER THE KEWEENAW AND NEAR LK SUP OVER
THE FAR E SHOULD SHIFT OUT INTO LK SUP.BY 00Z SAT...H85 TEMPS ARE
FCST TO RISE TO NEAR -5C ALONG THE WI BORDER...SO DAYTIME TEMPS
SHOULD MODERATE. BUT FCST HI STABILITY SHOWN ON FCST SDNGS WITH LO
SUN ANGLE INDICATES MAX TEMPS WL REMAIN WELL BLO NORMAL. A STEADY
SSW WIND WL MAKE THE AIR FEEL EVEN COLDER.

FRI NGT THRU SAT NGT...WITH INCRSG ISENTROPIC ASCENT IN THE
STRENGTHENING SW FLOW BTWN HI PRES MOVING OFF THE E COAST AND LO
PRES MOVING ACRS SCENTRAL CANADA...SOME OF THE MEDIUM RANGE MODELS
ARE GENERATING SOME LGT PCPN...MAINLY LATE FRI NGT INTO SAT AFTN
OVER THE ERN CWA WHERE LONGER DURATION OF ISENTROPIC ASCENT WL FAVOR
DEEPER MOISTENING SHOWN ON FCST SDNGS. BUT MARGINAL NATURE OF THE
DEEP MOISTENING JUSTIFIES NO MORE THAN CHC POPS EVEN OVER THE E.
SINCE THE MOISTENING MAY BE RATHER LO BASED AND THIS WARMING SFC
BASED MOIST LYR WL BE WARMER THAN -10C...MAINTAINED MENTION OF
FREEZING DZ LATE FRI NGT THRU SAT NGT WHERE TEMPS REMAIN
SUFFICIENTLY CHILLY. EXPECT A RELATIVELY MODEST DIURNAL TEMP DROP ON
FRI NGT WITH THE MIN TEMPS OCCURRING RELATIVELY EARLY. INCRSG SSW
WINDS AND CLDS ACCOMPANING THE WAD WL PROBABLY CAUSE TEMPS TO RISE
THRU MOST OF THE NGT. TEMPS ON SAT SHOULD RISE ABOVE 32 EVERYWHERE.

SUN THRU TUE...IN GENERAL THE LASTEST LONG RANGE GUIDANCE IS SHOWING
A FARTHER W TRACK FOR SFC LO THAT WL BE DVLPG IN THE MID MS RIVER
VALLEY ON SUN AS ASSOCIATED NEGATIVELY TILTED SHRTWV LIFTS NEWD IN
ADVANCE OF DEEPENING UPR TROF IN THE PLAINS. AS THIS SHRTWV RIDES TO
THE NNE...EXPECT STEADIER PCPN TO DVLP FM THE S ON SUN. SINCE THE LO
IS PROGGED TO TRACK N THRU UPR MI...WITH THE 00Z GFS/ECWMF
INDICATING A TRACK THRU THE CENTRAL CWA...EXPECT THE BULK OF THE
PCPN ON SUN TO FALL AS RA AS H85 TEMPS SURGE TO 2 TO 4C IN THE WARM
SE FLOW AHEAD OF THE NEGATIVELY TILTED SHRTWV. FCST SDNGS INDICATE
THE WARMING BE SFC BASED AS WELL WITH NO SGNFT FREEZING RA. ONCE THE
LO SHIFTS TO THE NNE OF UPR MI...WRAP ARND DEEP CYC W-NW FLOW WL
DRAW COLDER AIR BACK INTO THE UPR LKS AND CHG LINGERING PCPN BACK TO
SN ON MON. LES THEN LOOKS TO BE A GOOD BET ON TUE AS COLDER AIR
SURGES BACK INTO THE AREA ON THE HEELS OF GUSTY NW WINDS LEFT IN THE
WAKE OF THE DEPARTING LO MOVING THRU SE CANADA.

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z THURSDAY MORNING)
ISSUED AT 643 AM EST WED NOV 19 2014

LIGHT SNOW AHEAD OF A SURFACE TROUGH IS SPREADING EAST-NORTHEAST
ACROSS UPPER MICHIGAN THIS MORNING WILL REDUCE VISIBILITIES TO MVFR
VALUES FOR MUCH OF THE DAY TODAY. AS THIS TROUGH SHIFTS EAST
THROUGH WESTERN UPPER MICHIGAN THIS AFTERNOON...WINDS WILL SHIFT TO
THE WEST-NORTHWEST AND LAKE EFFECT SNOW WILL QUICKLY INTENSIFY AT
KIWD/KCMX AND CONTINUE THROUGH THE REST OF THE PERIOD. CURRENTLY
HAVE IFR CONDITIONS IN THE TAFS...BUT WOULD EXPECT OCCASIONAL
PERIODS OF LIFR VISIBILITIES IN THE HEAVIER BANDS. AT KSAW...ONCE
THE TROUGH MOVES THROUGH...THE SNOW WILL END AND CONDITIONS WILL
IMPROVE TO VFR. DID CONTINUE TO MENTION OCCASIONAL SNOW SHOWERS AND
SOME REDUCED VISIBILITIES WITH THE NORTHWEST WIND LAKE EFFECT...BUT
DON/T EXPECT CONDITIONS TO FALL TO MVFR.
&&

.MARINE...(FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE)
ISSUED AT 442 AM EST WED NOV 19 2014

AS A LO PRES TROF CROSSES THE UPPER GREAT LAKES TODAY...EXPECT A
WIND SHIFT FROM SW TO NW...WITH RAPIDLY INCREASING NW WINDS REACHING
GALE FORCE OVER THE WESTERN LAKE BY LATE THIS AFTERNOON. THE GALES
TO ABOUT 35 KTS WILL OVERSPREAD ALL BUT THE FAR EASTERN LAKE BY LATE
TONIGHT BEFORE DIMINISHING W TO E ON THU IN ADVANCE OF AN
APPROACHING HI PRES RIDGE. AS THIS HI SHIFTS INTO THE MID ATLANTIC
STATES ON FRI...THE WINDS WILL BACK FURTHER TO THE SSW AND INCREASE
UP TO 25-30 KTS BY SAT. EXPECT THESE WINDS TO DIMINISH LATER ON SAT
BEFORE BACKING TO THE E AND INCREASING UP TO 25-30 KTS ON SUN AHEAD
OF ANOTHER LO PRES MOVING NE TOWARD THE UPPER LAKES.
