SOLIDLY IN THE 35 TO 40 KNOT RANGE FOR AN EXTENDED PERIOD 18Z-03Z
SUNDAY. THE PASSING FRONTAL ZONE WILL BRING A CHANCE OF RAIN
THROUGH THE EARLY AFTERNOON PERIOD. A COOLING POST-FRONTAL THERMAL
PROFILE WILL SUPPORT A TRANSITION TOWARD SCATTERED SNOW
SHOWERS/FLURRIES FROM MID AFTERNOON ONWARD...ALTHOUGH ENOUGH
UNCERTAINTY EXISTS IN THE COVERAGE AND TIMING TO PRECLUDE A
SPECIFIC MENTION.

FOR DTW...CEILINGS WILL SETTLE BRIEFLY INTO IFR EARLY THIS MORNING.
SATELLITE TRENDS SUGGEST THIS DECK WILL CLEAR THE TERMINAL 08-09Z.
A LOWER CEILING WILL RETURN 12Z-15Z AS MOISTURE INCREASES AHEAD OF
AN APPROACHING LOW PRESSURE SYSTEM.  STRONG WESTERLY WINDS WILL
DEVELOP 18Z-20Z AND CONTINUE WELL INTO THE EVENING.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN CEILINGS BELOW 5000 FEET BRIEFLY EARLY THIS
MORNING.  CEILINGS WILL FIRMLY REMAIN BELOW 5000 FT FROM MID MORNING
ONWARD.

* HIGH CONFIDENCE THAT SUSTAINED WINDS WILL REACH 25 KNOTS FROM
260-270 DEGREES...WITH GUSTS TO 40 KNOTS SUNDAY AFTERNOON AND
EVENING.

.PREV DISCUSSION...ISSUED 701 PM EST SAT DEC 31 2011

SHORT TERM...TONIGHT

RICH BOUNDARY LAYER MOISTURE TRAPPED BENEATH A STRONG SUBSIDENCE
INVERSION HAS ALLOWED BL CLOUDS TO HANG TOUGH TODAY...AS
EXPECTED...WITH VERY FEW BREAKS OVER THE CWA AS OF EARLY THIS
AFTERNOON. THERE IS STILL A CHANCE FOR CLOUD COVER TO BREAK IN THE
FIRST HALF OF THE PERIOD AS THE FLOW TURNS SOUTHERLY AND WARM
ADVECTION DECREASES STABILITY BENEATH THE INVERSION...THOUGH IT IS
PROBABLY A MOOT POINT POINT AS MID AND HIGH CLOUDS WILL BE ON THE
INCREASE AT THE SAME TIME. SOUTH WINDS AND CLOUD COVER WILL KEEP LOW
TEMPERATURES IN CHECK OVERNIGHT...PERHAPS EVEN RISING A BIT BEFORE
SUNRISE.

ATTENTION THEN TURNS TO THE EARLY STAGES OF THE NEXT SYSTEM THAT
WILL AFFECT THE CWA MAINLY AFTER THE SHORT TERM PERIOD. WV IMAGERY
SHOWS THE UPPER CIRCULATION THAT WILL BE ROTATING INTO LOWER MI ON
SUNDAY MORNING CURRENTLY DIVING INTO THE WESTERN PLAINS. SATELLITE
TRENDS OFFER SUPPORT FOR RECENT SHORT TERM GUIDANCE...NAMELY THE RUC
AND 18Z NAM...WHICH ARE SLIGHTLY WEAKER AND A BIT SLOWER WITH THE
FORWARD PROGRESSION OF THE WAVE. FOR THE OVERNIGHT PERIOD...THIS
MOST CLOSELY RESEMBLES THE SOLUTION OF THE 12Z ECMWF. FOR THIS
REASON...SOME WEIGHT HAD TO BE GIVEN TOWARD THE POSSIBILITY OF A
WEAKER SURFACE CIRCULATION COME EARLY SUNDAY MORNING. THEREFORE...A
LESS AGGRESSIVE APPROACH WAS TAKEN WITH POPS FOR LATE TONIGHT
DESPITE THE FAVORABLE ISENTROPIC ASCENT/FGEN PROGS OFFERED BY THE
NAM/GFS. KEPT POPS ON THE LOW CHC END FROM US-23 EASTWARD AFTER 09Z
WITH AN INCREASE TOWARD 25-30 PER CENT FOR OUR EXTREME WESTERN AREAS.

LONG TERM...SUNDAY THROUGH FRIDAY

A STRONG SURFACE CYCLONE WILL DEEPEN ACROSS PORTIONS OF IOWA AND
NORTHERN ILLINOIS TONIGHT...EMERGING OUT ACROSS SOUTHERN LAKE
MICHIGAN BY THE START OF THE PERIOD SUNDAY.  THIS STRONG WINTER
SYSTEM IS ON THE DOCKET FOR NEW YEARS...BRINGING A FRESH BLAST OF
CONTINENTAL ARCTIC AIR TO SOUTHEASTERN MICHIGAN. AN EVENT THAT HAS
BEEN RATHER UNFAMILIAR THIS WINTER.

THE PARENT PV ANOMALY THAT IS RESPONSIBLE FOR THE SUBSTANTIAL LEE
TROUGH/NEBRASKA LOW CENTER HAS BEEN OUTSTANDING TODAY ON WV IMAGERY.
QUITE IMPRESSIVE TO SEE THIS CLOSED MIDLEVEL LOW ARRIVE IN THIS
PRISTINE OF SHAPE AFTER TRUDGING THROUGH THE ROCKY MOUNTAINS...AN
AREA WITH ENHANCED FRICTIONAL/SHEARING EFFECTS. THE 31.12Z RUN OF
THE ECMWF INITIALIZED CONSIDERABLY WEAKER WITH THE CYCLONIC
VORTICITY CENTROID OVER UT/ID IN COMPARISON TO THE NAM/GFS. IN
ADDITION...THE ECMWF IS SURPRISINGLY WEAK WITH THE ENTIRE TRAILING
JET CORE THAT WAS IN PLACE AT 12Z FROM UTAH CLEAR NORTHWESTWARD INTO
BRITISH COLUMBIA. THE GEM INITIALIZED WEAK WITH THE JET AS WELL.
THIS PRESENTS A CHALLENGE...AS THE USUAL DEPENDABLE ECMWF IS A
SOLUTION THAT IS DEFINING THE WEAK END OF THE ENVELOPE AND HAS SOME
ISSUES TO START. THIS CASTS SOME UNCERTAINTY AS IT ADVERTISES A LOW
STRENGTH FOR TOMORROW SOME 3 TO 9 MB WEAKER THAN THE NAM/GFS. THE
REASON FOR THE LONG WINDED DISCUSSION ON ALL OF THIS IS TO OUTLINE
THAT THERE ARE SOME NOTABLE DIFFERENCES YET IN THE
MODELS...SOMETHING THAT IN GREAT LIKELIHOOD WILL RESOLVE MUCH MORE
CLEANLY WITH THE 00Z SET OF RAOBS.

SATELLITE REPRESENTATION AND THE PROGGED NEGATIVE TILT RESPONSE
DIRECTLY INTO SOUTHEASTERN MICHIGAN TOMORROW MIDDAY LENDS SUPPORT
FOR A STRONGER SYSTEM RESPONSE LOCALLY ACROSS SOUTHEASTERN MICHIGAN.
GFS IS LIKELY TOO STRONG WITH THE SURFACE LOW/DESPITE A FAVORABLE
DEEPENING BOOST FROM THE UNSTABLE GREAT LAKES. JUST AM NOT OVERLY
ECSTATIC FOR THE QUALITY OF PHASING ON THE SYNOPTIC SCALE ACCORDING
TO THE TROPOPAUSE MAPS. WOULD LIKE TO SEE THE TRAILING ANOMALY WRAP
INTO THE LOW PRIOR TO ARRIVAL AND THIS CLEARLY DOES NOT HAPPEN WITH A
HEALTHY AMOUNT OF SEPARATION. REGARDLESS...THE TILTING ACTION OF THE
LEAD ANOMALY WILL BRING A STRONG AGEOSTROPHIC AND FRONTOGENETIC
RESPONSE. RESULTANT ISENTROPIC DOWNGLIDE SHOULD BE EFFICIENT
TOMORROW AND THE POTENTIAL REMAINS THAT WINDGUSTS COULD REACH/EXCEED
50 KNOTS FROM LATE MORNING THROUGH THE EARLY EVENING HOURS. WITH THE
LINGERING UNCERTAINTY AND AN EVENT THAT WILL BE SOLIDLY IN PERIOD 2
WILL MAINTAIN THE CURRENT HIGH WIND WATCH HEADLINE BUT TWEAK THE
TIMING. THE SOLUTION FOR THE MORNING HOURS HAS TRENDED QUITE A BIT
WARMER/STABLE...DID SWITCH PTYPE TO A STRAIGHT RAIN PRIOR TO THE
START OF CAA. DEPTH OF MOISTURE AND DYNAMICS ARE LACKING FOR A
PRECIPITATION EVENT...CHANCE POPS WILL SUFFICE.

ONLY POTENTIAL HIGH IMPACT ISSUE TO CONTEND WITH WILL BE
EVOLUTION OF SURFACE TRAJECTORIES OVER THE GREAT LAKES MONDAY
THROUGH WEDNESDAY. THIS WILL HAVE A SIGNIFICANT IMPACT ON LAKE
EFFECT SNOW POTENTIAL. ATM...CURRENT MODEL SOLUTIONS SUGGEST THAT
THE WIND DIRECTION WILL REMAIN ENOUGH WESTERLY WHERE SNOW WILL NOT
BE AN ISSUE. ONE SPECIFIC FEATURE WILL BE A THERMAL TROUGH THAT
WILL PIVOT DOWN LAKE HURON MONDAY NIGHT. THIS MAY SCRAPE ENOUGH
INLAND TO SWITCH SURFACE TRAJECTORIES BRIEFLY TO THE
NORTHEAST...LEADING TO SOME ACCUMULATIONS ALONG THE FAR EASTERN
THUMB. TOO EARLY TO CALL ON THIS. OTHERWISE COLD TEMPERATURES WITH
20S ON MONDAY GIVING WAY TO TEENS/TO AROUND 20 FOR DAYTIME HIGHS
ON TUESDAY.

MARINE...

STRONG GALES WILL DEVELOP OVER AREA WATERS DURING THE DAY ON SUNDAY
WITH CENTRAL WITH THE POSSIBILITY OF LOW END STORM FORCE WIND GUSTS
OVER MOST OF THE OPEN WATERS OF LAKE HURON. A STRONG LOW CURRENTLY
TAKING SHAPE OVER THE CENTRAL PLAINS WILL LIFT INTO THE CENTRAL
GREAT LAKES ON SUNDAY MORNING. AS IT DOES SO...SUSTAINED GRADIENT
WINDS WILL TURN SOUTHERLY AND INCREASE APPRECIABLY INTO THE 20-30
KNOT RANGE. GUSTS WILL INITIALLY BE LIMITED TO LOW END GALES AS THE
SOUTHERLY FLOW WILL MAINTAIN SOME STABILITY OVER THE LAKES.
HOWEVER...THE PRESSURE GRADIENT WILL INCREASE MARKEDLY BY SUNDAY
AFTERNOON INTO SUNDAY NIGHT AS THE LOW PRESSURE CENTER SHIFTS TOWARD
NORTHERN LAKE HURON. AS WINDS VEER TO WESTERLY BEHIND A STRONG COLD
FRONT SUSTAINED GALES CAN BE EXPECTED OVER THE OPEN WATERS OF LAKE
HURON WITH GUSTS POTENTIALLY REACHING STORM FORCE AND WAVES REACHING
15 TO 20 FEET. THE GALE WATCHES FOR THESE AREAS HAVE THEREFORE BEEN
UPGRADED TO STORM WATCHES. THE EXISTING GALE WATCHES REMAIN IN PLACE
FOR SAGINAW BAY AND THE NEARSHORE ZONES WHILE WESTERN LAKE ERIE AND
LAKE SAINT CLAIR HAVE BEEN UPGRADED TO GALE WARNING STATUS. FREEZING
SPRAY WILL ALSO BECOME AN ISSUE ON LAKE HURON DURING THE DAY ON
MONDAY AS MUCH COLDER AIR PLUNGES INTO THE REGION.
