AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
1035 AM EST FRI FEB 18 2011

.UPDATE...

IMPRESSIVE WIND SPEEDS ACROSS THE KEWEENAW PENINSULA THIS
MORNING...WITH CMX REPORTING A PEAK WIND OF 68 MPH AT 838 AM THIS
MORNING. AN INCREDIBLE 81 MPH PEAK WIND REPORTED AT STANNARD ROCK AT
930AM THIS MORNING. DECIDED TO EXPAND THE HIGH WIND WARNING TO
ONTONAGON COUNTY WITH THE WEATHER SITE REPORTING STEADY 40+ MPH
WINDS THROUGH THE MORNING...ALTHOUGH THE STRONGEST WINDS ARE LIKELY
CONFINED TO THE SHORELINE NE OF ONTONAGON.

OVERALL...THE GOING FORECAST WAS IN REALLY GOOD SHAPE SO ONLY MINOR
CHANGES WERE NEEDED. DO NOT REALLY EXPECT MUCH IMPROVEMENT OF THE
WINDS UNTIL TONIGHT AS STRONG PRESSSURE RISES CONTINUE THROUGH THE
DAY AS WELL AS ANOTHER SURGE OF COLD ADVECTION ALOFT ASSOCIATED WITH
THE 850MB TROUGH AXIS. THEREFORE...AM THINKING THAT ALTHOUGH THE
WIND GUSTS WILL LIKELY SUBSIDE SOME THIS AFTERNOON ACROSS THE
KEWEENAW...THE FACT REMAINS THAT THIS WIND EVENT WILL MOST LIKELY BE
A FAIRLY LONG LIVED EVENT...WITH STRONG WINDS EXTENDING WELL INTO
THE NIGHT FOR LUCE/ALGER COUNTIES.

LOOKS LIKE TEMPS WILL BE STEADY OR SLOWLY FALL TODAY WITH THE STRONG
COLD ADVECTION. PLACES THAT HAVE SEEN SUNSHINE THIS MORNING ARE A
LITTLE WARMER THAN FORECAST AND WILL NEED TO BE ADJUSTED.
OTHERWISE...EXPECT TEMPS TO FALL INTO THE TEENS WEST AND LOW-MID 20S
EAST BY EVENING.
&&

PREV DISCUSSION...ISSUED AT 631 AM EST FRI FEB 18 2011...

.SYNOPSIS...

00Z RAOBS/LATEST WV IMAGERY AND RUC ANALYSIS SHOW WSW FLOW ALF OVER
MUCH OF THE CONUS BTWN MEAN UPR RDG OVER THE SE AND GENERAL TROFFING
OVER THE W. A PAIR OF SHRTWVS EMBEDDED WITHIN THIS FLOW ARE NEARBY.
THE FIRST IS E OF THE FA. ALTHOUGH OVERALL DRYNESS OF THE MID LVLS
OF AIRMASS IN PLACE PER 00Z APX/GRB RAOBS LIMITED THE ACCOMPANYING
PCPN OVER THE FA TO MAINLY SOME -DZ...A FEW LTG STRIKES WERE NOTED
OVER NE LK SUP ARND 03Z FRI WITH STEEP LAPSE RATES ABV UNSEASONABLY
WARM LLVL AIRMASS THAT HAS DOMINATED THE LAST COUPLE OF DAYS. IN
FACT... THE 00Z H7 TEMP AT GRB WAS AN IMPRESSIVE +2C...WITH HIEST
TEMP ARND 12C AT H83. PLENTY OF LLVL MSTR LINGERING UNDER THE SHARP
INVRN HAS LED TO AREAS OF FOG ACRS THE FA OVER MELTING SN PACK. NEXT
SHRTWV OF INTEREST IS LIFTING ENEWD INTO MN...WITH 12HR H5 FALLS IN
EXCESS OF 100M. ACCOMPANYING SFC/H85 LO IS IN ONTARIO JUST N OF
INL...AND ATTENDANT COLD FNT HAS SURGED INTO WRN UPR MI AS OF 04Z.
BUT THERE IS A COMPLETE LACK OF PCPN ALG THIS FNT WITH SHARP DRY
SLOTTING AS SHOWN ON THE 00Z MPX/INL RAOBS. STRONG NW FLOW...WITH
H85-7 WNW WINDS AOA 50KTS IN THE NRN PLAINS...IS DRIVING MUCH COLDER
AIR EWD INTO MN. AS OF 04Z...THE SFC TEMPS IN NW MN HAVE FALLEN INTO
THE 5-10F RANGE. THIS SHARP CAD HAS ENHANCED THE MIXING OF THE
STRONGER WINDS ALF TO THE SFC...WITH WIND GUSTS NEAR 40KTS AT
SEVERAL LOCATIONS. THE STRONG ISALLOBARIC WIND COMPONENT IN ADVANCE
OF CENTER OF GREATEST PRES RISES AOA 5MB/3HRS IN ERN NDAKOTA ON THE
SRN FLANK OF SFC LO IS ALSO IN LINE WITH THE GRADIENT W FLOW AND
PROVIDING ADDITIONAL ENHANCEMENT. WIND GUST REACHED 53 MPH AT DLH AT
05Z.
&&

.DISCUSSION...

MAIN FCST CONCERNS INTO SAT ARE RELATED TO WINDS/GOING HEADLINES AS
WELL AS POTENTIAL FOR LES. FOCUS FOR LATER IN THE FCST TURNS TO SN
CHCS LATER IN THE WEEKEND ASSOCIATED WITH NEXT SFC LO EMERGING FM
THE DESERT SW.

TDAY...AS SHRTWV NOW NW OF THE FA SLIDES ACRS ONTARIO...SFC LO IS
FCST TO LIFT NE TO NEAR JAMES BAY BY 00Z SAT. STRONG NW SFC FLOW IS
PROGGED OVER THE FA BTWN THE DEPARTING LO AND SFC HI PRES NOSING
INTO THE NRN PLAINS. STRONG CAD WITH H85 TEMPS FALLING TO ARND -20C
OVER THE KEWEENAW BY 00Z SAT WL STEEPEN SFC-H85 LAPSE RATES AND
ENHANCE MIXING OF H925-85 WINDS UP TO 50-60KTS TO THE SFC. ALTHOUGH
SHARPEST PRES RISE CENTER IS FCST TO LIFT MORE NE INTO ONTARIO
CLOSER TO THE LO TRACK...STILL FAVORABLE ISALLOBARIC WIND COMPONENT
WL ENHANCE THE TOTAL WIND. GOING WIND HEADLINES APPEAR ON TRACK WITH
HI WIND WRNGS IN THE EXPOSED KEWEENAW AND ALGER/LUCE COUNTIES.
QUESTION IS WHETHER TO EXTEND WIND ADVY TO THE MORE SHELTERED
SCNTRL. GUIDANCE DOES INDICATE THE STRONGEST CAD WL PASS TO THE N OF
MNM...AND THERE IS A FAIRLY SHARP GRADIENT OF WIND GUSTS UPSTREAM
BTWN CNTRL MN AND IOWA. SINCE THE 05Z WIND GUST WAS SO HI AT DLH AND
THE GFS/LOCAL WRF-ARW BUFKIT PROFILES FOR MNM AND ESC INDICATE WIND
GUSTS TO 40-45 KTS ARE LIKELY THERE...OPTED TO EXTEND ADVY TO THE
ENTIRE CWA. AS FOR LES...THE DEEPEST BACKWASH MSTR IS PROGGED TO
LIFT MORE NE THRU ONTARIO AND NOT IMPACT THE FA. ALTHOUGH THE
AIRMASS WL BECOME SUFFICIENTLY COLD TO SUPPORT LES IN THE WNW WIND
SN BELTS OVER THE KEWEENAW THIS MRNG AND THEN E OF MUNISING IN THE
AFTN...THE STRONG WINDS WL FRAGMENT THE SN FLAKES...LOWERING
SN/WATER RATIOS...AND DISRUPT SN BAND ORGANIZATION. SLOWLY VEERING
LLVL FLOW WL ALSO LIMIT RESIDENCE TIME OF THE SN BANDS. ALTHOUGH THE
SMALLER FLAKES WL MORE EFFICIENTLY REDUCE VSBY...OPTED TO AVOID LES/
BLSN HEADLINES AND FOCUS ON THE GREATER HI WIND HAZARD IN THE
WARNING AREAS OF THE KEWEENAW/ALGER/LUCE. OTRW...CONSIDERING THE
STRONG CAD AND CORRELATION BTWN OBSVD SFC TEMPS/H85 TEMPS
UPSTREAM...TENDED TO LOWER SFC TEMPS FASTER THAN PREVIOUS FCST MORE
IN LINE WITH THE LOCAL WRF-ARW PROGS.

TNGT...HI PRES IN THE NRN PLAINS WL BE MOVING EWD UNDER FAIRLY SHARP
H5 RISES UP TO 120M IN THE WAKE OF DEPARTING SHRTWV. WITH RELAXING
PRES GRADIENT W-E...EXPECT THE STRONG WINDS TO DIMINISH AS WELL...
LAST OVER THE E. LES WL ALSO DIMINISH W-E AS NAM/GFS FCST SDNGS SHOW
INVRN BASE LOWERING STEADILY TOWARD 2K FT AT CMX AFT 06Z. LES WL BE
MORE PERSISTENT OVER THE E...BUT STRONG AND STEADILY VEERING WINDS
TO MORE NW WL LIMIT RESIDENCE TIME/SN TO WATER RATIOS. BUT WITH
LONGER FETCH ACRS LK SUP AND FCST SDNGS SHOWING SHARPEST OMEGA
WITHIN THE FAVORABLY PLACED DGZ BTWN 2-4K FT...SN ACCUMS MAY APRCH
ADVY LVL IN THIS AREA WHERE LLVL CYC FLOW/SHARPER CNVGC LINGERS
LONGEST.

SFC HI PRES RDG IS FCST TO BLD OVER THE UPR GRT LKS ON SAT...WITH
RDG AXIS EXTENDING FM CENTER OVER NW ONTARIO INTO CNTRL UPR MI LATER
IN THE DAY. GFS SHOWS A STRIPE OF PCPN DVLPG OVER THE WRN CWA LATE
IN THE DAY UNDER SHARPER H85-7 FGEN/ISENTROPIC ASCENT ON THE 285K
SFC WHERE RETURN SLY FLOW SETS UP. NAM SHOWS AN AREA OF HIER MID LVL
RH IN THIS AREA BUT NO PCPN...AS THAT MODEL HOLDS THE SHARPER FGEN
TO THE W. SHIFTED GOING POPS INTO THIS AREA OVER THE FAR W TO
REFLECT THIS CONSENSUS OF AT LEAST HIER MID LVL RH. BUT WENT ONLY
SCHC ON THE POPS WITH AREA UNDER UPR CNVGC IN RIGHT EXIT OF H3 JET
MAX IN SCNTRL CAN AND LLVL DRY AIR HOLDING FIRM.

SAT NGT...AS SFC RDG AXIS SHIFTS GRDLY TO THE E...LARGER SCALE WAD
IS FCST TO DVLP OVER THE UPR GRT WITH ISENTROPIC ASCENT BEST SHOWN
ON THE 285-290K SFCS. WITH LLVL ESE FLOW ON THE SW FLANK OF
DEPARTING HI PRES RDG...EXPECT THE NEAR SFC DRY AIR TO BE MOST
TENACIOUS OVER THE SE FA. SO KEPT POPS OUT OF THIS AREA. BUT DID
BUMP POPS UP A BIT HIER OVER THE NW CWA AFT 06Z WHEN UPR JET
CROSSING SRN CAN MOVES INTO ONTARIO AND PLACES THAT AREA UNDER THE
RRQ QUADRANT...WITH SOME UPR DVGC FCST NEAR PERSISTENT AXIS OF HIER
H85-7 FGEN. TENDED TO RAISE GOING MIN TEMPS TOWARD CONSENSUS TEMPS
FCST WITH THICKENING CLD COVER.

FOR SUN...MODEL FLIP FLOPS CONT...WITH 00Z GFS NOW TRENDING A BIT
FARTHER S WITH LO TRACK ACCOMPANYING SHRTWV LIFTING NEWD FM THE
DESERT SW. ON THE OTHER HAND...THE 00Z NAM/ECMWF ARE FARTHER N. IN
FACT...THE 00Z ECMWF SHOWS ALMOST 0.75 INCH QPF OVER THE SCNTRL
18Z-24Z SUN IN AREA WHERE GUIDANCE HINTS THERE MAY BE ENHANCED UPR
DVGC IN LEFT EXIT OF JET MAX TRACKING INTO THE LOWER LKS AND RRQ OF
JET IN SE CAN. CONSIDERING NCEP PREFERENCE FOR A BLEND OF THE 00Z
GFS/00Z ECMWF...WHICH BOTH SHOW HEAVIER PCPN OVER THE SCNTRL...
OPTED TO BUMP POPS UP A BIT IN THAT AREA TO HI LIKELY/CATEGORICAL.
WITH FGEN ON THE NRN FLANK OF LO CROSSING TO THE S AND STRENGTHENING
NE FLOW...TENDED TO GO TOWARD THE LO END OF GUIDANCE FOR MAX TEMPS.

DRY AIR FEEDING IN FM HI PRES OVER ONTARIO AND FARTHER N OF SFC LO
TRACK THRU THE LOWER GRT LKS WL TEND TO LIMIT QPF OVER THE NRN TIER
ON SUN NGT INTO MON...BUT SOME LK MOISTENING JUSTIFIED MAINTAINING
HIER POPS IN THE UPSLOPE AREAS OVER THE NRN TIER. STEADY SN SHOULD
CONT OVER THE SCNTRL...ESPECIALLY IF THE SOMEWHAT FARTHER N ECMWF
VERIFIES AND SHARPER FGEN IS OVER THAT AREA. AT LEAST THE SRN TIER
OF THE CWA WL LIKELY REQUIRE SOME SN HEADLINES FOR THIS EVENT. SINCE
THE SN WL NOT START UNTIL LATE IN THE 5TH PERIOD...WL HANDLE WITH
SPS FOR NOW AND LEAVE POTENTIAL WATCH ISSUANCE FOR LATER SHIFTS.
&&

.AVIATION /FOR THE 06Z TAF ISSUANCE/...

EXPECT MVFR CIGS TO PREVAIL AT BOTH TAF SITES THROUGH THE PERIOD AS
A DRIER AND MORE TURBULENT AIRMASS TAKES HOLD OVER THE REGION. MUCH
COLDER AIR FLOODING THE AREA IN THE WAKE OF A STRONG COLD FRONT WILL
RESULT IN STRONG GUSTY WRLY WINDS AT BOTH TAF SITES. WINDS WILL
LIKELY GUST OVER 40 KT AT KSAW AND COULD GUST AS HIGH AS 50 KT AT
KCMX IN FAVORABLE WRLY FLOW ON FRIDAY. THE WESTERLY FLOW OF COLD AIR
OFF LAKE SUPERIOR WILL ALSO LIKELY GENERATE LAKE EFFECT SNOW SHOWERS
AT KCMX. THE SNOW COMBINED WITH BLOWING FROM THE STRONG WINDS SHOULD
LOWER VSBYS DOWN TO AT LEAST IFR DURING THE DAY ON FRIDAY AT KCMX...
AND THEN AS WINDS VEER MORE TO NORTHWEST FRI EVENING EXPECT VSBYS TO
IMPROVE TO MVFR. GIVEN WRLY FLOW...WOULD NOT EXPECT MORE THAN A FEW
FLURRIES AT KSAW WITH NO RESTRICTION TO VISIBILITY.
&&

.MARINE /FOR 4AM LAKE SUPERIOR FORECAST ISSUANCE/...

A STRONG LOW PRESSURE SYSTEM JUST NORTH OF LAKE SUPERIOR WILL MOVE
TO JAMES BAY TODAY. COLD AIR WRAPPING AROUND THE LOW WILL LEAD TO
STORM FORCE WINDS TO 50 KNOTS ACROSS MUCH OF LAKE SUPERIOR TODAY. A
HIGH PRESSURE RIDGE PUSHING EAST FROM THE NORTHERN PLAINS TONIGHT
WILL DIMINISH THE WINDS FROM WEST TO EAST TONIGHT INTO SATURDAY.
HEAVY FREEZING SPRAY WILL ALSO OCCUR ACROSS LAKE SUPERIOR TODAY
THROUGH SATURDAY MORNING. A LOW PRESSURE SYSTEM MOVING OUT OF THE
CENTRAL PLAINS ON SATURDAY NIGHT AND INTO THE LOWER GREAT LAKES ON
SUNDAY...WILL BRING THE POTENTIAL FOR NORTHEAST GALES TO 35 KNOTS ON
SUNDAY NIGHT. HIGH PRESSURE WILL ONCE AGAIN MOVE OVER THE AREA BY
MONDAY NIGHT...REDUCING WINDS TO LESS THAN 20 KNOTS.
