AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
656 PM EST THU FEB 9 2012
.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 435 PM EST THU FEB 9 2012
A 500MB LOW IS CURRENTLY OVER FAR NRN QUEBEC...WHERE IT WILL STAY
THROUGH AT LEAST FRIDAY. A 500MB TROUGH IS MOVING AROUND THE W SIDE
OF THIS LOW AND CURRENTLY STRETCHES FROM THE LOW CENTER TO CENTRAL
MANITOBA. AT THE SFC...AN ARCTIC COLD FRONT AND ASSOCIATED TROUGH IS
CURRENTLY JUST N OF THE CWA. VERY DRY AIR IN THE LOW AND MID LEVELS
KEPT SKIES CLEAR...EXCEPT FOR SOME HIGH CLOUDS...ALLOWING
TEMPERATURES TO CLIMB INTO THE MID 30S ACROSS MOST OF UPPER MI THIS
AFTERNOON.
THE COLD LOOKS TO MOVE INTO THE KEWEENAW SHORTLY AFTER 00Z FRI
/ORIENTED IN A WSW TO ENE DIRECTION/...BUT FINE SCALE MODELS SUGGEST
A LAKE ENHANCED BAND MAY FORM OVER OVER THE KEWEENAW A COUPLE OF
HOURS AHEAD OF THE FRONT IN WLY WINDS AS 850MB TEMPS FALL TO AOB
-10C. DO NOT HAVE HIGH POPS FOR THE PRE FRONTAL LES BAND SINCE AIR
WILL BE SO DRY INITIALLY. BY 03Z FRI...MODELS SHOW THE COLD FRONT
FROM JUST N OF THE HURON MOUNTAINS TO NEAR IRONWOOD. BY 06Z FRI...THE
FRONT SHOULD BE FROM NEAR GRAND MARAIS TO IRON MOUNTAIN. THEN BY 09Z
FRI...THE FRONT SHOULD BE JUST S OF THE ENTIRE CWA. EXPECT A GOOD
BURST OF SNOW RIGHT ALONG THE FRONT...ESPECIALLY IN UPSLOPE AREAS
NEAR LAKE SUPERIOR...WHERE SOUTH CENTRAL UPPER MI WILL LIKELY ONLY
SEE MINOR SNOW ACCUMULATIONS TONIGHT. LES WILL THEN ORGANIZE BEHIND
THE FRONT AS 850MB TEMPS FALL TO AROUND -18C RIGHT BEHIND THE
FRONT...AND WILL BE COLDEST AROUND 12Z AS LOW AS -25C. LOW LEVEL
WINDS BEHIND THE FRONT WILL BE NEARLY UNIDIRECTIONAL FROM AROUND 000
TO 010 DEGREES...PUTTING N WIND FAVORED AREAS UNDER THE GUN FOR THE
BEST LES. WITH THE ARRIVAL OF THE COLDEST AIR AROUND 12Z FRI WILL
ALSO COME DRIER MID LEVEL AIR AND LOWERING INVERSION HEIGHTS AS SFC
RIDGING PUSHES IN FROM THE NW. BY 18Z FRI...AIR WILL BE QUITE DRY
ABOVE 850MB...WITH A MORE INVERTED V TYPE SOUNDING IN THE LOW LEVELS
DUE TO DAYTIME HEATING. THIS WILL LEAD TO DIMINISHING LES THROUGH THE
DAY FRI...WITH ONLY SOME SCATTERED SNOW SHOWERS BY LATE IN THE DAY.
AS FAR AS SNOWFALL AMOUNTS AND HAZARDS...THE HEAVIEST SNOW SHOULD
FALL ALONG AND JUST BEHIND THE COLD FRONT...AND WOULD CONTINUE
LONGER EXCEPT FOR THE DRY AIR MOVING IN SO QUICKLY. THE PREVIOUS
FORECAST HAS SNOW TOTALS IN THE 3 TO 5 INCH RANGE OVER THE FAVORED N
WIND SNOWBELTS...WHICH IS JUST SUB LES ADVISORY /5 INCHES IN 12
HOURS/. THIS LOOKS REASONABLE GIVEN HIGH SNOW TO LIQUID RATIOS IN
THE 20-25 TO 1 RANGE SINCE THE BEST LIFT WILL BE IN THE DGZ DURING
THE EXPECTED TIME OF HEAVIEST SNOW. HIGH RESOLUTION MODELS SUCH AS
THE NCEP HIGH RES WRF-ARW/NMM THE LOCAL HIGH RES WRF WOULD SUGGEST
HIGHER SNOW TOTALS...BUT THOSE APPEAR TO BE OVERDOING AMOUNTS. WILL
USE THOSE MODELS FOR FROPA/PRECIP TIMING...BUT WILL UNDERPLAY THEIR
QPF AMOUNTS. WINDS WILL BE GUSTY...SO THERE WILL BE SOME VISIBILITY
RESTRICTIONS. WILL NOT ISSUE ANY HEADLINES AT THIS TIME DUE TO THE
FACT THAT THE HEAVIEST PRECIP WILL FALL WELL BEFORE MORNING COMMUTE
AND AMOUNTS SHOULD BE SUB ADVISORY AT MOST.
TEMPS THU NIGHT AND FRI WILL BE VERY CHILLY...ESPECIALLY COMPARED TO
OUR TEMPS AS OF LATE. LOWS TONIGHT WILL RANGE FROM NEAR 0F OVER
INTERIOR W AND FAR ERN UPPER MI...TO THE LOW TEENS OVER E CENTRAL
UPPER MI. HIGHS ON FRI WILL NOT BE MUCH WARMER. OVER THE W HALF OF
UPPER MI...EXPECT HIGHS AROUND 10F...WITH HIGHS IN THE TEENS OVER
THE E HALF OF UPPER MI. WIND CHILLS WILL ALSO BE A
CONCERN...ALTHOUGH NOT LOW ENOUGH FOR ANY HEADLINES. EXPECT WIND
CHILL VALUES AS LOW AS THE NEGATIVE TEENS LATE TONIGHT THROUGH
FRIDAY MORNING...THEN AGAIN FRIDAY EVENING.
.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 435 PM EST THU FEB 9 2012
THE AO WHICH HAS BEEN POSITIVE NEARLY CONTINUALLY FROM EARLY NOV HAS
BECOME NEGATIVE IN THE LAST FEW WEEKS. HOWEVER...THE NAO HAS
REMAINED POSITIVE...SO THE WARM WINTER PATTERN HAS CONTINUED FOR
UPPER MI DESPITE THE AO TURNING NEGATIVE. SINCE NOV 1...THE AVG TEMP
HERE AT THE NWS OFFICE HAS BEEN 24.9F...MAKING THIS THE 3RD WARMEST
NOV 1-FEB 8 PERIOD ON RECORD. THE WARMEST NOV 1-FEB 8 PERIOD
OCCURRED IN 2001-2002 WITH AN AVG TEMP OF 28.1F. OVER THE NEXT WEEK
OR SO...IT LOOKS LIKE THE AO WILL REMAIN NEGATIVE...BUT LESS SO...
WHILE THE NAO TRENDS TOWARD NEUTRAL/NEGATIVE. THIS WILL PROBABLY
RESULT IN ABOVE NORMAL TEMPS ON THE WHOLE THRU NEXT WEEK. HOWEVER...
THERE WILL BE A PERIOD OF COLDER AIR/BLO NORMAL TEMPS OVER THE NEXT
FEW DAYS AS DEEP POLAR VORTEX CENTERED JUST NE OF HUDSON BAY SWINGS
A PORTION OF ITS ASSOCIATED ARCTIC AIRMASS INTO THE GREAT LAKES
REGION IN RESPONSE TO A RIDGE THAT HAS BUILT N THRU THE NW
TERRITORIES. AFTER THE PUSH OF ARCTIC AIR OVER THE NEXT FEW DAYS...
THE NRN STREAM WILL RETREAT WITH PATTERN TAKING ON A DISTINCT SPLIT
FLOW NEXT WEEK. WHETHER OR NOT THIS SPLIT FLOW LEADS TO ANY SRN
STREAM SYSTEMS REACHING THE UPPER GREAT LAKES REMAINS TO BE SEEN.
RIGHT NOW...IT APPEARS THAT THE OVERALL DRY PATTERN WILL PERSIST
NEXT WEEK.
BEGINNING FRIDAY NIGHT...WITH 850MB TEMPS AROUND -20C...LES WILL BE
ONGOING IN AREAS FAVORED BY NW WINDS. DRY AIR/LOW INVERSION BLO 4KFT
AND HINTS OF INVERTED-V/WELL-MIXED BOUNDARY LAYER WILL KEEP LES
LIGHT INITIALLY. HOWEVER...WITH THE DENDRITIC SNOW GROWTH TEMP ZONE
(DGZ) IN THE CONVECTIVE LAYER...MIGHT STILL BE ABLE TO FLUFF UP A
FEW INCHES OF SNOW LOCALLY...HIGHEST OVER THE NE FCST AREA WHERE
LONGER OVERWATER FETCH CAN WORK TO OFFSET DRY AIR. WINDS OVER FAR SW
UPPER MI MAY BACK SUFFICIENTLY TO CUT OVERWATER TRAJECTORIES ENOUGH
TO ALLOW FOR SOME CLEARING. TEMPS THERE SHOULD FALL INTO THE SINGLE
DIGITS BLO ZERO. ELSEWHERE...TEMPS SHOULDN'T FALL BLO THE SINGLE
DIGITS/LWR TEENS AS SFC-925MB WINDS MAINTAIN A FLOW OFF OF LAKE
SUPERIOR.
LOOKS LIKE LES WILL RAMP UP SAT/SAT EVENING AS A SHORTWAVE DROPS S
AROUND POLAR VORTEX CENTERED NE OF JAMES BAY. WITH 850MB TEMPS
MODERATING SLIGHTLY...DGZ RISES A BIT AND BECOMES MORE IDEALLY
POSITIONED IN THE CONVECTIVE LAYER/UPWARD MOTION REGION. RISING
INVERSION/DEEPER MOISTURE PROFILE AND CONVERGENT NORTHWESTERLY FLOW
ALL POINT TO POTENTIAL HEADLINE EVENT...MORE LIKELY ADVY GIVEN THE
SHORT WINDOW WHERE ALL PARAMETERS LINE UP BEST (UPWARD MOTION IN
DGZ/DEEP MOISTURE/HIGHER INVERSION HEIGHTS). LONGER FETCH AND LONGER
DURATION OF MORE FAVORABLE LES PARAMETERS SUGGEST BEST SNOW
ACCUMULATIONS WILL BE OVER THE NE FCST AREA. OVER WRN LAKE
SUPERIOR...FLOW IS MORE WESTERLY. AS IS OFTEN THE CASE WITH WESTERLY
WINDS IN THAT AREA...ENHANCED CONVERGENCE COULD SET UP BTWN THE
PORCUPINE MTNS AND HOUGHTON DUE TO A SLIGHTLY MORE SOUTHERLY WIND
COMPONENT TOWARD THE APOSTLE ISLANDS AND A MORE NORTHERLY COMPONENT
TOWARD ISLE ROYALE. SO...BEST SNOW ACCUMULATIONS IN WRN UPPER MI
WILL PROBABLY OCCUR IN THAT AREA. LES WILL WIND DOWN ALONG WITH
DECREASING CLOUDS W TO E LATER SAT NIGHT INTO SUN AS WAA BEGINS. BY
SUN EVENING...AIR MASS SHOULD BE WARM ENOUGH TO BRING AN END TO ANY
LINGERING LES OVER THE NE FCST AREA.
MON THRU THU...AS ALLUDED TO ABOVE...NRN STREAM RETREATS WITH SPLIT
FLOW BEING THE RULE NEXT WEEK. STILL LOOKS LIKE A SRN BRANCH WAVE
MOVING INTO THE MID MISSISSIPPI VALLEY MON MAY BRING THE NRN END OF
ASSOCIATED -SN SHIELD INTO PORTIONS OF SRN UPPER MI. NOTHING MORE
THAN LOW CHC/SLIGHT CHC POPS ARE WARRANTED. BENIGN/DRY WEATHER THEN
FOLLOWS TUE/WED. EVEN LES WON'T BE A CONCERN WITH CONSENSUS 850MB
TEMPS WARMER THAN -8C. HEADING INTO THU...GFS/ECMWF INDICATE NRN
STREAM ENERGY PASSING BY TO THE N WHILE ANOTHER SRN STREAM SYSTEM
MOVES TO THE MID MISSISSIPPI VALLEY. TRACK OF NRN WAVE N OF UPPER MI
SUGGESTS MINIMAL PCPN THREAT HERE....AND SIMILAR TO THE PREVIOUS SRN
BRANCH WAVE...PCPN WITH THE SRN SYSTEM WILL LARGELY PASS BY TO THE
S. SO...OPTED FOR A DRY FCST FOR THU. RETREATING NRN STREAM AND
SPLIT FLOW SUGGESTS TEMPS WILL RETURN TO ABOVE NORMAL VALUES NEXT
WEEK.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING)
ISSUED AT 655 PM EST THU FEB 9 2012
A COLD FRONT WILL MOVE THROUGH THE TAF SITES EARLY IN THE FCST
PERIOD. THE MAIN CONCERN IS THE TIMING OF THE FRONTAL PASSAGE AT
EACH SITE AND THE BEGINNING OF LAKE EFFECT SNOW. INITIAL STAGES OF
THE PASSAGE WILL RANGE FROM 01Z AT CMX TO 05Z AT SAW. EXPECT QUICKLY
VEERING WINDS WITH THE FRONTAL PASSAGE AND AN INCREASE IN
WINDS...ESPECIALLY AT CMX. LAKE EFFECT SNOW AND BLOWING SNOW WILL
ALSO BEGIN SHORTLY AFTER THE FRONTAL PASSAGE. CONDITIONS WILL LIKELY
FALL TO IFR VIS WITH MAINLY MVFR CIGS. CONDITIONS WILL START TO IMPROVE
FRIDAY MORNING AS DRY AIR MOVES IN.
&&
.MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)
ISSUED AT 435 PM EST THU FEB 9 2012
AN ARCTIC COLD FRONT WILL MOVE ACROSS LAKE SUPERIOR THIS
EVENING...USHERING IN MUCH COLDER AIR. EXPECT OCCASIONAL NORTHERLY
GALE GUSTS TO 35KTS AND HEAVY FREEZING SPRAY...ESPECIALLY ACROSS THE
CENTRAL AND EASTERN LAKE. A LULL IN THE WINDS AND HEAVY FREEZING
SPRAY CAN BE EXPECTED FRIDAY AFTERNOON AS A LOW LEVEL RIDGE BUILDS
IN FROM THE NORTH. THEN FROM FRIDAY NIGHT THROUGH SATURDAY
NIGHT...AN INCREASING PRESSURE GRADIENT FROM A RIDGE IN THE NORTHERN
PLAINS BUILDING IN ON THE BACK SIDE OF THE DEPARTING EASTERN TROUGH
WILL BRING NORTHWESTERLY GALES TO 35KTS AND HEAVY FREEZING SPRAY TO
PORTIONS OF LAKE SUPERIOR. CONDITIONS QUIET DOWN FOR THE REMAINDER
OF THE PERIOD STARTING SUNDAY AS THE RIDGE MOVES OVER THE UPPER
GREAT LAKES.
