URGENT - MARINE WEATHER MESSAGE
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
358 PM EST THU NOV 12 2015

...SOUTHWEST GALES TO CONTINUE INTO FRIDAY...

.STRONG SOUTHWEST WINDS HAVE NOW OVERSPREAD MUCH OF THE AREA AS DEEP
LOW PRESSURE TRACKS INTO NORTHERN LAKE HURON THIS AFTERNOON. SOLID
GALE FORCE WINDS HAVE BEEN COMMON FROM SOUTHERN LAKE HURON SOUTH TO
THE MICHIGAN WATERS OF LAKE ERIE WITH WESTERN LAKE ERIE ENCROACHING
ON STORM FORCE GUSTS AT TIMES. EXPECT THESE BASIC CONDITIONS TO
PERSIST INTO THE EVENING AND ONLY EASE SLIGHTLY OVERNIGHT. 

GIVEN THIS EXPECTATION...WILL ONLY HAVE TO ADJUST A FEW HEADLINES
WITH THIS FORECAST. WILL BE CANCELING THE LOW WATER STATEMENT FOR
SAGINAW BAY AS WATER LEVELS ARE JUST NOW EDGING BELOW CHART DATUM
AND THE FORECAST CALLS FOR THESE LEVELS TO BASICALLY HOLD INTO THE
EVENING AND THEN SLOWLY RISE OVERNIGHT AS WINDS VEER TO THE WEST
SOUTHWEST.

ALSO...WILL DOWNGRADE THE STORM WARNING FOR LAKE ST CLAIR TO A GALE
WARNING AS NEXT PERIOD OF ENHANCED WIND GUSTS LATE THIS AFTERNOON
INTO EARLY THIS EVENING LOOKS TO ONLY LEAD TO OCCASIONAL GUSTS INTO
THE 40 TO 45 KNOT RANGE. THE WESTERN PORTION OF LAKE ERIE WILL
PROBABLY BE SOME 3 TO 5 KNOTS HIGHER ON AVERAGE...WHICH SUPPORTS THE
CONTINUATION OF THAT PORTION OF THE STORM WARNING AS GUSTS APPROACH
STORM FORCE AT TIMES AT THE VERY LEAST.

A SECOND SYSTEM IS STILL EXPECTED TO DROP INTO THE AREA ON FRIDAY IN
THE WAKE OF THIS EXITING STORM. THIS WILL LEAD TO PERSISTENT GALE
FORCE WIND GUSTS INTO FRIDAY ACROSS MUCH OF THE MARINE WATERS. COLD
AIR PUSHING DOWN TO THE NORTH OF A DEVELOPING THERMAL TROUGH WILL
ALLOW STRONGER NORTHWEST WINDS TO PUSH DOWN INTO THE NORTHERN LAKE
HURON BASIN. FOR THIS REASON...THE GALE WATCH WILL BE UPGRADED TO A
WARNING FOR AT LEAST MARGINAL GALE CONDITIONS FRIDAY AFTERNOON AND
EVENING.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1137 AM EST WED NOV 11 2015

.AVIATION...

THE FIRST HALF OF THE TAF PERIOD WILL START OUT QUIET AS CLEAR SKIES
GIVE WAY TO SOME MID/HIGH CLOUDS...WITH ABRUPT ARRIVAL OF SHOWERS
AND MVFR CEILINGS LATE TONIGHT (BRIEF IFR POSSIBLE)...FOLLOWED BY
VERY STRONG WINDS DURING THURSDAY...AS POWERFUL LOW PRESSURE SYSTEM
TRACKS INTO WESTERN GREAT LAKES TONIGHT...AND THROUGH NORTHERN LOWER
MICHIGAN TOMORROW. THERE IS A SLIGHT CHANCE OF THUNDERSTORMS LATE
TONIGHT...BUT CERTAINLY NOT HIGH ENOUGH TO INCLUDE MENTION IN THE
TAFS. THE ARRIVAL OF STRONG WINDS LOOKS TO BE IN THE 12-15Z TIME
FRAME...BEHIND THE COLD FRONTAL PASSAGE. COLD ADVECTION AND DEEP
LAYER MIXING DURING THE DAY ON THURSDAY WILL MAINTAIN STRONG
SOUTHWEST WINDS...WHICH LOOK TO BE AT OR ABOVE 25 KNOTS
SUSTAINED...WITH FREQUENT GUSTS OF 40 TO 45 KNOTS...STRONGEST WINDS
ACROSS SOUTHERN TAF SITES...DTW...YIP...AND DET...WHERE
BRIEF/ISOLATED GUSTS MAY APPROACH 50 KNOTS.

FOR DTW...STRONG COLD FRONT EXPECTED TO MOVE THROUGH 12-14Z TIME
WINDOW THURSDAY MORNING. INCREASING SOUTHWEST WINDS /220-240
DIRECTION/ WITH THIS FRONTAL PASSAGE WITH HIGH CONFIDENCE IN WIND
GUSTS OCCASIONALLY IN EXCESS OF 40 KNOTS THROUGH THE DAY.

//DTW THRESHOLD PROBABILITIES...

* HIGH FOR CEILING BELOW 5000 FT LATE TONIGHT INTO THURSDAY.

.PREV DISCUSSION...ISSUED 433 AM EST WED NOV 11 2015

SHORT TERM...TODAY AND TONIGHT

RAPIDLY DEEPENING CLOSED LOW AND ATTENDANT STRONG UPPER JET FORCING
NOW LIFTING OUT OF THE FRONT RANGE OF THE ROCKIES WILL INITIATE A
SIZABLE LOW LEVEL RESPONSE DOWNSTREAM OVER THE NEXT 48 HOURS.
SUBSTANTIAL CYCLOGENESIS OF THE RESULTING SURFACE LOW WILL COMMENCE
AS THE SYSTEM RACES NORTHEAST FROM THE CENTRAL PLAINS TODAY TO
ROUGHLY THE STRAITS BY THURSDAY AFTERNOON.  THE IMMEDIATE IMPACT
LOCALLY FOR THE DAYULIGHT PERIOD TODAY WILL SIMPLY BE A PERIOD OF
INCREASED UPPER HEIGHTS AS THE FLOW BUCKLES DOWNSTREAM OF THESE
HEIGHT FALLS.  PLENTY OF DRY AMBIENT AIR WITHIN A BACKGROUND OF WEAK
SUBSIDENCE WILL SUPPORT A HIGH DEGREE OF SUNSHINE...ALTHOUGH SOME
PESKY MID CLOUD NOW DRIFTING ACROSS WISCONSIN MAY ENCROACH NORTHERN
SECTIONS BY MIDDAY.  MODEST MIXING POTENTIAL UP THROUGH 925 MB UNDER
THE EXISTING LOW LEVEL SOUTHEAST FLOW WILL SUPPORT THE UPWARD
ADJUSTMENT IN TEMPERATURES TODAY.  HIGHS MID AND UPPER 50S.

WING OF PRONOUNCED MID LEVEL ASCENT EMERGES ALONG THE LEAD EDGE OF
THE INBOUND HEIGHT FALLS ACROSS THE MID MS VALLEY/MIDWEST TODAY...
FAVORABLE EXIT REGION JET DYNAMICS AND INCREASING UPPER DIFFLUENCE
LOCKING ONTO THE TREMENDOUS HEIGHT FALL GRADIENT. THE STRENGTHENING
DEEP LAYER SOUTHWEST FLOW WILL LODGE A SUBSTANTIAL COMPONENT OF
MOISTURE ADVECTION INTO THIS BACKGROUND FORCING FIELD...NETTING A
LEAD CORRIDOR OF SHOWERS THAT OUTPACES THE INBOUND STRONG COLD FRONT
BY 4-5 HOURS.  UNIFORM MODEL CONSENSUS IN CENTERING THIS MOISTURE
AXIS OVER THE REGION 06Z-10Z EARLY THURSDAY MORNING.  DIMINISHING
MID LEVEL STABILITY /850-750 MB/ WILL PRESENT A LIMITED WINDOW/
OPPORTUNITY FOR SOME ELEVATED THUNDER DURING THIS TIME. COLD FRONT
ITSELF AT THE DOORSTEP OF THE SOUTHWEST COUNTIES BY 11-12Z THURSDAY
MORNING.  SOME HI RES SOLUTIONS LEAVE THE POSSIBILITY FOR A TRAILING
LOW TOPPED LINE OF CONVECTIVE SHOWERS TO ALIGN WITH THIS ROBUST
FEATURE.  THIS SCENARIO WOULD PRESENT THE POTENTIAL FOR SHOWERS TO
AUGMENT/EHHANCE THE RAPIDLY ASCENDING MIXED LAYER ALONG THE FRONTAL
INTERFACE...OPENING THE DOOR FOR AN INITIAL BRIEF PERIOD OF STRONGER
GUSTS /IN EXCESS OF 50 MPH/.  THE ONSET TIMING OF THE HIGH WIND
WATCH STARTS AT 11Z TO CAPTURE THIS POTENTIAL.  FOR ADDITIONAL
ASSESSMENT ON WIND POTENTIAL FOR THURSDAY...SEE LONG TERM SECTION.

LONG TERM...

ATTENTION OF THE LONG TERM PERIOD WAS PLACED SQUARELY ON THE WIND
POTENTIAL FOR THURSDAY AND FRIDAY. A DESCRIPTION OUTLINING THE MAIN
SYNOPTIC SCALE FEATURES RESPONSIBLE FOR THE WIND EVENT CAN BE FOUND
IN PREVIOUS DTX AREA FORECAST DISCUSSIONS. THE 11.00Z NWP SUITE
ARRIVED WITH NO SIGNIFICANT DEVIATIONS FROM PRIOR THINKING. THE
BIGGEST TRENDS IDENTIFIED IN THE LATEST MODEL DATA WAS A SLIGHT
SOUTHWARD JOG OF THE SURFACE LOW TRACK WITH THE BROAD LOW CENTER
DOWN INTO NORTHERN LOWER MICHIGAN AND A SLIGHTLY SLOWER SOLUTION IN
SURFACE COLD FRONT TIMING.

THERE APPEARS TO BE TWO SEPARATE FORCING MECHANISMS THAT WILL
BRING STRONG WINDS TOMORROW...POTENTIALLY EXCEEDING 55 MPH. THE
FIRST OPPORTUNITY...WILL BE TIED TO ANY SHALLOW LOW-TOPPED
CONVECTION THAT CAN DEVELOP ALONG THE INITIAL COLD AIR SURGE/SURFACE
THETA E COLD FRONT. THE SECOND OPPORTUNITY WILL DEVELOP DURING THE
AFTERNOON AS THE COLD AIR ADVECTION DEEPENS AND ALIGNS THE
PRESSURE GRADIENT FAVORABLY TO THE DEEP WESTERLY FLOW.

THE INITIAL SFC THETA E GRADIENT/COLD FRONT IS FORECASTED TO SLIDE
THROUGH THE CWA TOMORROW BETWEEN 11-14Z FROM WEST TO EAST. MODEL
SOUNDINGS REMAIN STEADFAST IN GENERATING A POCKET OF INSTABILITY IN
THE 900-800MB LAYER. WILL BE INTERESTING TO SEE WHAT SORT OF LIGHT
THE CAMS WILL SHED ON OVERALL CONVECTIVE POTENTIAL DEVELOPING WITHIN
THIS CORRIDOR OF ENHANCED INSTABILITY...THE MOST RECENT 4KM-SPC WRF-
NMM DOES HINT AT A BROKEN LINE OF SHOWERS AT HOUR 36. THE MOST
DISCONCERTING ASPECT OF THIS SYSTEM...EVEN EARLY ON IS THE DEPTH OF
THE STRONG KINEMATIC FIELD ALONG THE SOUTHERN FLANK OF THE DEEP
CYCLONIC CIRCULATION. MODEL SOUNDINGS ARE IN STRONG AGREEMENT THAT
45-55 KNOTS WILL RESIDE IN THE COLUMN BETWEEN 1000 AND 5000 FT AGL.
THE BEST PRESSURE GRADIENT FORCE IS EXPECTED TO BECOME ESTABLISHED
SOUTH OF THE M 59 CORRIDOR BEFORE 18Z...THEN EXPANDING NORTHWARD AS
THE OCCLUSION/WARM CORE LIFTS INTO NORTHERN LAKE HURON. INCREASING
UNIDIRECTIONAL WEST FLOW WILL THEN ALLOW THE DEEPER COLD AIR
ADVECTION TO FILTER ACROSS LOWER MICHIGAN DURING THE AFTERNOON.
MIXING HEIGHTS APPEAR TO BE A LITTLE COMPROMISED WITH A LACK OF
REAL DRY AIR...BUT A STRONG MODEL GUIDANCE SUGGESTS WINDS OF UP TO
45 KNOTS AT THE TOP OF THE MIXED LAYER. WITH THESE FACTORS IN
CONSIDERATION FELT THERE WAS A 50 PERCENT CONFIDENCE IN WIND
REACHING 55 TO 60 MPH. AS A RESULT...THE DECISION WAS MADE TO
ISSUE A HIGH WIND WATCH FOR THE COUNTIES ALONG AND SOUTH OF THE
INTERSTATE 69 CORRIDOR FROM 11Z THURSDAY TO 03Z FRIDAY.

MODEL DATA CAME IN WITH AN EVEN FASTER SOLUTION FOR THE TRAILING
WAVE...ENTERING INTO THE ENTRANCE REGION OF THE JET AT 21- 00Z
THURSDAY. THE MODELS THEN SCREAM THIS ENERGY THROUGH SEMICH THE
LATTER HALF OF THE NIGHT. WILL SAY THERE IS QUITE A BIT OF
UNCERTAINTY WITH EXACTLY HOW THE WIND EVOLUTION WILL PLAY OUT
THURSDAY NIGHT...ESPECIALLY WITH THE SECOND MIDLEVEL COLD AIR
ADVECTION EVENT AND SUBSIDENCE/ASCENT THAT WILL ACCOMPANY THE
SHORTWAVE. MODELS SHOW A VERY GOOD MIXED LAYER THROUGH THE
DURATION OF THE NIGHT. THERE REMAINS PLENTY OF TIME TO REFINE THE
FRIDAY FORECAST AS FUTURE SHIFTING OF THE SOLUTION SPACE WILL
OCCUR BECAUSE OF THE IMPENDING WAVE INTERACTIONS. LATEST THINKING
IS THAT WINDS WILL ACTUALLY WEAKEN SOMEWHAT DURING THE DAY FRIDAY
AS A SURFACE TROUGH WILL BE DRAGGED SOUTHWARD THROUGH THE AREA.

MARINE...

STRONG LOW PRESSURE WILL TRACK FROM THE CENTRAL PLAINS TODAY TO THE
STRAITS BY THURSDAY. A TIGHT PRESSURE GRADIENT ON THE SOUTH SIDE OF
THE LOW COMBINED WITH STRONG LOW LEVEL JET WINDS MIXING TO THE
SURFACE WILL RESULT IN A PERIOD OF STRONG WINDS...REACHING GALE
FORCE ACROSS THE EASTERN LAKES ON THURSDAY. THE POTENTIAL EXISTS FOR
GUSTS TO REACH STORM FORCE ACROSS THE MICHIGAN WATERS OF LAKE ERIE
AND LAKE ST CLAIR. A SECOND SYSTEM QUICKLY FOLLOWING THE PRIMARY
STORM ON FRIDAY WILL LEAD TO A CONTINUED THREAT OF GALES FOR SOME OF
THE MARINE ZONES AS COLDER UNSTABLE AIR MOVES INTO THE REGION.
