Blizzard and Winter Storm in Michigan, February 17 to 20, 2009

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MARQUETTE MI
640 AM EST TUE FEB 17 2009

UPDATED FOR 12Z TAF ISSUANCE

...TRAVEL STRONGLY DISCOURAGED WEDNESDAY AFTERNOON THROUGH THURSDAY
MORNING OVER MQT AND ALGER COUNTIES DUE TO POSSIBLE BLIZZARD
CONDITIONS...

.SYNOPSIS...
10Z WATER VAPOR LOOP AND RUC 500MB HEIGHT ANALYSIS SHOWED SPLIT FLOW
ACROSS NORTH AMERICA...WITH NUMEROUS FEATURES TO WATCH FOR THE
UPCOMING MID-WEEK STORM SYSTEM. THE SOUTHERN BRANCH FEATURES A LARGE
TROUGH MOVING INTO CA WITH A POTENT SHRTWV IN SE CA...THEN RIDGING
DOWNSTREAM ACROSS THE CENTRAL PLAINS INTO THE LOWER MS VALLEY. IN
THE NORTHERN STREAM...RIDGING COVERS WESTERN CANADA AND A BROAD
TROUGH COVERS CENTRAL CANADA. WITHIN THIS BROAD TROUGH...A STRONG
SHRTWV WAS PRESENT OVER NE SASKATCHEWAN AND AN UPPER LOW WAS IN NRN
ONTARIO. A SHRTWV WAS ALSO PRESENT IN NE MN. UPPER MI LIES IN ZONAL
FLOW BETWEEN THE TWO BRANCHES. RADAR IMAGERY SHOWS SOME LIGHT PCPN
ASSOCIATED WITH WARM ADVECTION AND VERY WEAK DPVA AHEAD OF THE NE MN
SHRTWV. LIFT IS CONCENTRATED ON THE 280-285K SFCS. PCPN HAD A HARD
TIME REACHING THE GROUND FOR MUCH OF THE NIGHT...DUE TO LOW LEVEL
DRY AIR SEEN ON THE 00Z GRB SOUNDING. EVEN CLOUD BASES ARE STILL
GENERALLY VFR. CLOUDS EXTEND WESTWARD INTO THE NORTHERN PLAINS. THE
CLOUDS HAVE HELPED TEMPS STAY UP...WITH MOST LOCATIONS IN THE LOW TO
MID 20S. ANOTHER FACTOR KEEPING THE TEMPS UP IS A SOUTHERLY WIND
AHEAD OF A SFC TROUGH THAT STRETCHES FROM NRN LK SUPERIOR SW ACROSS
DLH AND INTO WRN NEBRASKA. RETURN FLOW SOUTH OF THE TROUGH IS
HELPING TO BRING MORE MOISTURE NORTHWARD...THOUGH DEWPOINTS DO NOT
REFLECT TRUE GULF OF MEXICO MOISTURE YET GIVEN THAT THEY ARE ONLY IN
THE 20S AND 30S IN THE CENTRAL PLAINS. UP TO THE NW...COLDER AIR
EXISTS ASSOCIATED WITH THE UPPER LOWS...NOTED BOTH BY SFC AND 850MB
TEMPS. AMAZING DIFFERENCE ACTUALLY AT 850MB...WITH GRB AT -8C AND
CWPL AT -24C AT 00Z. THIS COLD AIR WILL COME INTO PLAY FOR THE
MID-WEEK SNOW.

&&

.DISCUSSION...

TODAY...SHRTWV OVER NE MN WILL MOVE ACROSS THE CWA THIS MORNING...
CAUSING THE SFC TROUGH OVER WRN LAKE SUPERIOR TO FLATTEN OUT ALONG
THE LK SUPERIOR/UPPER MI SHORELINE...THEN THE UPPER FLOW IS GOING TO
TURN SOUTHWEST AS THE UPPER LOW IN NE SASKATCHEWAN DIVES DOWN INTO
SOUTHERN MANITOBA. WITH THE UPPER FLOW TURNING SW...THE SFC TROUGH
WILL BASICALLY BECOME STATIONARY. THE SETUP SUGGESTS PERSISTENT WEAK
ISENTROPIC LIFT OVER THE CWA...BUT IT MAY MOVE NORTHWARD DURING THE
AFTN AS THE FLOW TURNS TO THE SW. THEREFORE...HAVE KEPT HIGHEST POPS
IN THE NORTHERN CWA AND OUT OVER LK SUPERIOR. THE STRONGEST PORTION
OF THE LIFT IS ACTUALLY OVER ERN UPPER MI...SO THE MOST SNOW SHOULD
OCCUR THERE. AMOUNTS NOT REALLY EXPECTED TO BE ALL THAT MUCH...MAYBE
AN INCH OR TWO OVER ERN UPPER MI WITH LESS THAN AN INCH ELSEWHERE...
GIVEN THE WEAK LIFT. GIVEN CLOUDY SKIES PLANNED TODAY...WARMING
MOSTLY WILL COME FROM ADVECTION AND WEAK INSOLATION. GENERALLY
FOLLOWED A BLEND OF GUIDANCE FOR HIGHS.

TONIGHT...SHRTWV CURRENTLY IN SE CA WILL BE MOVING ACROSS THE
ROCKIES AND INTO SE CO/SW KS BY 00Z. DOWNSLOPING FLOW OFF THE
ROCKIES AND DPVA AHEAD OF THIS SHRTWV IS EXPECTED TO RESULT IN A
995MB LOW NEAR TOPEKA KS AT 00Z. SINCE RIDGING EXISTS DOWNSTREAM OF
THE SHRTWV...THE SHRTWV WILL LIFT UP TOWARDS NRN MO BY 12Z WED...
WITH THE SFC LOW LIFTING INTO NRN IL. MEANWHILE...THE SHRTWV IN SRN
MANITOBA WILL ALSO BE DROPPING DOWN INTO THE NORTHERN PLAINS AND
BEGINNING TO DRAG THE UPPER LOW IN NRN ONTARIO WITH IT. WHAT THIS
MEANS FOR THE CWA IS ANOTHER ROUND OF WARM ADVECTION SEEN ON
280-285K SFCS...BUT THE ACTUAL ISENTROPIC LIFT IS FAIRLY WEAK.
HOWEVER...MID LEVEL FRONTOGENESIS WILL BE INCREASING WITH TIME OVER
THE CWA...WHICH SHOULD CAUSE PCPN TO EXPAND. IN ADDITION...THE AREA
BEGINS TO FALL IN THE RIGHT ENTRANCE REGION OF A 60-70KT JET STREAK
ON THE SOUTH SIDE OF THE NRN ONTARIO UPPER LOW...AIDING IN UPPER
DIVGC. NEW 06Z NAM/LOCAL WRF-ARW ARE EVEN A BIT FASTER THAN THEIR
PREVIOUS RUNS IN PCPN EXPANSION...WHICH WILL NEED TO BE LOOKED AT BY
THE DAY SHIFT. GIVEN THE RELATIVELY WARM AIRMASS IN PLACE...WOULD
NORMALLY EXPECT LOW SNOW TO WATER RATIOS. HOWEVER...MUCH OF THE LIFT
OCCURS IN THE DGZ AND THE OVERALL DEPTH OF AGGREGATION IS FAIRLY
SMALL. THEREFORE HAVE KEPT WITH THE IDEA OF RATIOS AROUND 15 TO 1.
OVERALL...LOOKS LIKE A GENERAL 2 TO POSSIBLY 4 INCHES ACROSS THE
CWA. TEMPS WILL PROBABLY BE SLOW TO FALL DURING THE EVENING...BUT
THEN TAKE A MUCH MORE RAPID FALL IN WRN UPPER MI AFTER MIDNIGHT AS
THE SFC TROUGH BEGINS TO SINK SOUTH AND WINDS TURN NE. GENERALLY
STAYED CLOSE TO A BLEND OF THE LOCAL WRF-ARW RUN AND MAV GUIDANCE
FOR LOWS...WITH A BIT OF THE MET INCLUDED AS WELL TO ACCOUNT FOR THE
POSSIBILITY OF A FASTER COLD AIR INTRUSION.

WED INTO THU...FOCUS IS ON THREE ITEMS...THE SFC LOW AND SHRTWV
COMING UP FROM NRN IL...THE SHRTWV DROPPING DOWN INTO THE NORTHERN
PLAINS AND THE NRN ONTARIO UPPER LOW. DURING THE DAY WED...THE
SHRTWV OVER THE NORTHERN PLAINS WILL MOVE INTO IA AND WRN WI WHILE
AT THE SAME TIME PULLING THE NRN ONTARIO UPPER LOW DOWN TOWARDS
THUNDER BAY. AS THESE TWO ARE MOVING SOUTHWARD...THEY MAY BEGIN TO
INTERACT WITH THE SHRTWV COMING UP FROM NRN IL. THE AMOUNT OF
INTERACTION STILL REMAINS A QUESTION...WITH THE UKMET/REGIONAL
CANADIAN HAVING THE MOST WHILE THE NAM IS THE LEAST. THE 00Z ECMWF
AND TO SOME EXTENT THE GFS ARE AROUND THE MIDDLE OF THE ROAD. AFTER
HOLDING A CONFERENCE CALL WITH WESTERN GREAT LAKES OFFICES AND
HPC...DECIDED TO FOLLOW CLOSE TO THE 00Z ECMWF FOR HANDLING OF THE
FEATURES. SEE THE PMDHMD DISCUSSION FROM HPC FOR MORE DETAILS.

THE SFC LOW OVER NRN IL SHOULD STRENGTHEN AS IT LIFTS TOWARDS THE
THUMB OF LOWER MI BY 00Z THU...TO AROUND 988MB. AS IT PASSES BY TO
OUR SOUTH...WINDS WILL TURN NORTHERLY AND INCREASE WEST TO EAST
THROUGH THE DAY WED. THE INCREASE IN WINDS WILL BE AIDED BY COLD
ADVECTION FROM THE UPPER LOW AND SHRTWV DROPPING SOUTHWARDS TOWARDS
THE AREA. IN FACT...BY 00Z THU...850MB TEMPS SHOULD FALL TO -18C
OVER WESTERN SUPERIOR. SIMILAR COOLING WILL BE FELT AT THE SFC...AND
THEREFORE NON-DIURNAL TREND IS INDICATED IN HOURLY TEMP FORECASTS.
AHEAD OF THIS COOLING...A BAND OF FAIRLY STRONG MID-LEVEL
FRONTOGENESIS/FRONTOLYSIS WILL MOVE SLOWLY WEST TO EAST ACROSS THE
CWA. POTENTIAL EXISTS FOR 2-4 INCHES OF SYNOPTIC SNOW FROM THIS
CIRCULATION...SINCE STRONG LIFT IS PRESENT WITHIN AND ABOVE THE
DENDRITIC GROWTH ZONE. HOWEVER...THIS CIRCULATION WILL ALSO BE ON
TOP OF THE COOLING 850MB TEMPS...IE THE DEVELOPING LAKE EFFECT. THE
BEST JUXTAPOSITION OF THESE FEATURES OCCURS OVER NORTH CENTRAL UPPER
MI DURING WED AFTN AND EVENING. IN FACT...THE LAKE EFFECT/UPSLOPE
COMPONENT SHOULD IMPROVE EVEN MORE DURING THE EVENING AS SOUNDINGS
SHOW INVERSION HEIGHTS RISING TO 825MB. TO MAKE MATTERS WORSE...THE
WIND FIELDS REALLY INCREASE TOWARDS EVENING OVER EASTERN SUPERIOR
INTO NORTH CENTRAL UPPER MI...WITH SPEEDS OF 40-45 KT DEPICTED IN
THE MIXED LAYER...GIVING AN IDEA OF THE GUSTS. UPPER LOW CURRENTLY
IN NRN ONTARIO SHOULD DROP SOUTH OVER UPPER MI WED NIGHT...BRINGING
THE CORE OF THE COLD AIR ACROSS. WIND CHILLS COULD END UP DROPPING
TO -20F BY THU MORNING OVER WRN UPPER MI. ON THU...THE UPPER LOW
WILL SHIFT EAST INTO NEW ENGLAND...TAKING THE SYSTEM WITH IT.
HOWEVER...THE POTENTIAL WILL NEED TO BE MONITORED FOR THE SYSTEM TO
ROTATE BACK TO THE WEST...AS SHOWN IN THE PAST FEW GFS RUNS.
OVERALL...THOUGH...SNOW FOR MOST LOCATIONS ON WED NIGHT SHOULD
SWITCH TO LAKE EFFECT. GREATEST AMOUNT OF LAKE EFFECT EXPECTED IN
CENTRAL UPPER MI...EVEN INTO DELTA AND SRN SCHOOLCRAFT COUNTIES DUE
TO THE STRONG WINDS. AMOUNT OF SNOW IN WRN UPPER MI IS SORT OF
UNKNOWN WITH THE FAIRLY EXTENSIVE ICE COVERAGE PRESENT. FOR SNOW
RATIOS DURING THE EVENT...KEPT THEM GENERALLY 25 TO 1 OR LESS...DUE
TO SUBSTANTIAL WIND CAUSING SOME FRACTURING OF THE SNOW CRYSTALS.
OVERALL...DESPITE THE DIFFERENCES IN THE MODEL
TRACKS/INTENSITIES...QPF FORECASTS WERE IN GOOD AGREEMENT. ONLY
ADJUSTMENT WAS TO KEEP HIGHER QPF THAN THE NAM SHOWED FOR WRN UPPER
MI DUE TO ITS POORER HANDLING OF THE ICE.

HAZARD DISCUSSION...WITH SNOW COMING IN AFTER MIDNIGHT (POSSIBLY
EARLIER AS SHOWN BY THE 06Z NAM/LOCAL WRF-ARW RUNS)...DECIDED TO
ISSUE SOME HEADLINES NOW. CONFIDENCE WAS HIGH ENOUGH TO PUT
ADVISORIES UP FOR WRN UPPER MI AND WARNINGS FOR MQT/ALGER COUNTIES.
ICE COVERAGE ON WESTERN SUPERIOR WAS THE ONLY ITEM THAT PREVENTED
FAR WRN UPPER MI FROM HAVING A WINTER STORM WARNING. MUCH DISCUSSION
WAS GIVEN FOR THE WARNING TYPE FOR MQT/ALGER COUNTIES. SNOW WILL
START ACCUMULATING TONIGHT THROUGH WED MORNING...THEN WINDS KICK UP.
BLIZZARD CONDITIONS SEEM LIKELY WED AFTERNOON THROUGH THU MORNING...
BUT WITH A 12 HOUR WINDOW OF SUB-BLIZZARD CONDITIONS EXPECTED
(BASICALLY BEFORE 18Z WED)...DECLINED TO ISSUE THE BLIZZARD WARNING
RIGHT NOW. LATER SHIFTS AS WE GET CLOSER TO THE EVENT WILL LIKELY
NEED TO UPGRADE. FOR DELTA/SCHOOLCRAFT/LUCE...EITHER A HIGH END
ADVISORY OR WARNING IS PLANNED. GIVEN THE UNCERTAINTY ON WHICH ONE
TO GO WITH...DECIDED TO ISSUE A WINTER STORM WATCH FOR NOW.
AGAIN...IF THE SNOW DEVELOPS MORE INTENSE OVER THE EAST HALF OF
UPPER MI AS THE NEW 06Z NAM INDICATES...A WARNING MIGHT BE MORE
APPROPRIATE. IRON...DICKINSON AND MENOMINEE COUNTIES MAY NEED A
WINTER WEATHER ADVISORY FOR BLOWING SNOW AT SOME POINT...BUT RIGHT
NOW NO HEADLINE SHOULD SUFFICE.

BEYOND THU...VERY FEW CHANGES MADE DUE TO TIME SPENT ON THE UPCOMING
STORM.

.AVIATION (FOR THE 12Z TAF ISSUANCE)...

CMX...EXPECT -SN TO DIMINISH THIS MRNG WITH PASSAGE OF DISTURBANCE
TO THE E...BUT PREDOMINANT MVFR CIGS WL REMAIN CLOSE TO INCOMING LO
PRES TROF THRU THE DAY. ARRIVAL OF ANOTHER DISTURBANCE TNGT WL BRING
MORE SN...WITH CONDITIONS DETERIORATING TO IFR OVERNGT.

SAW...EXPECT -SN/MVFR CONDITIONS TO DIMINISH BY NOON...WITH
CONDITIONS TRENDING TOWARD VFR MOST OF THE DAY WITH RELATIVELY DRY
SW FLOW AHEAD OF INCOMING LO PRES TROF. THIS TROF WL ARRIVE THIS
EVNG AND SERVE AS A FOCUS FOR SOME HEAVIER SN WITH CONDITIONS
DETERIORATING TO IFR LATER TNGT.

&&

.MARINE (FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE)...

MAIN FCST CONCERN DURING THIS FCST PERIOD INVOLVES LOW PRES MOVING
FROM THE PLAINS LATE TODAY TO THE LOWER GREAT LAKES ON WED AND
SOUTHEAST CANADA ON THU. TIGHTENING PRES GRADIENT BTWN THE LOW AND
HIGH PRES BUILDING FROM MANITOBA INTO THE NRN PLAINS WILL CAUSE N TO
NE GALES ACROSS ALL BUT FAR WESTERN LAKE SUPERIOR WED THRU THU.
SINCE INCREASINGLY COLDER AIR WILL ALSO BE SPREADING OVER THE
AREA...HEAVY FREEZING SPRAY WILL ALSO DEVELOP IN ICE FREE AREAS
DURING THIS TIME. THE WINDS/HEAVY FREEZING SPRAY WILL DIMINISH W-E
THU INTO FRI.
