URGENT - MARINE WEATHER MESSAGE
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
346 AM EST TUE FEB 2 2016

...EASTERLY GALES OVER LAKE HURON...

.EASTERLY WINDS WILL INCREASE DURING THE DAY AS A RESULT OF A
TIGHTENING GRADIENT BETWEEN LOW PRESSURE LIFTING INTO THE MIDWEST
AND HIGH PRESSURE ANCHORED OVER EASTERN CANADA. THERE WILL BE A
SHALLOW UNSTABLE LAYER OVER LAKE HURON WHICH WILL SUPPORT SOME GUSTS
TO GALE FORCE OVER PORTIONS OF THE LAKE. THE TIME PERIOD OF
STRONGEST WINDS WILL BE FROM 5 PM THIS EVENING UNTIL ROUGHLY 2 AM
TONIGHT. WARMER AIR ADVANCING ACROSS LAKE ERIE WILL LIKELY RESULT IN
VERY HIGH STABILITY AND THUS MAKE IT MUCH LESS LIKELY THAT GALE FORCE
WIND GUSTS WILL BE ABLE TO MAKE IT TO THE SURFACE ON LAKE ERIE. THE
SURFACE LOW WILL MOVE INTO THE WESTERN GREAT LAKE TONIGHT ALREADY
OCCLUDING. THE GRADIENT WILL ACTUALLY RELAX CONSIDERABLY AS THE LOW
APPROACHES...LEADING TO WEAKENING WINDS LATE TONIGHT INTO WEDNESDAY
MORNING. THE LOW IS FORECAST TO TRACK ACROSS NORTHERN LAKE HURON
WEDNESDAY AFTERNOON BEFORE LIFTING INTO CANADA WED NIGHT.
STRENGTHENING SOUTHWEST WINDS WILL RESULT /ESPECIALLY ACROSS THE SRN
HALF OF THE LAKE/ AS THIS LOW PASSES THROUGH. THERE IS REASONABLY
HIGH PROBABILITY THAT THE SOUTHWEST WIND GUSTS WILL REACH 25 TO 30
KNOTS. THERE IS A CHANCE THAT WIND GUSTS MAY REACH GALE FOR A SHORT
PERIOD WED AFTERNOON AND EVENING.

.SECONDARY SURFACE LOW DEVELOPMENT HAS TAKEN HOLD OVER SOUTHWEST
LOWER MICHIGAN EARLY THIS MORNING. THIS LOW WILL LIFT INTO NORTHERN
LAKE HURON BY LATE MORNING...WHILE THE SFC LOW NOW OVER IOWA WEAKENS
INTO MORE OR LESS A TROUGH AXIS. WINDS WILL DECREASE DURING THE

CANADA DURING THE AFTERNOON...CAUSING WINDS TO SHIFT TO THE
SOUTHWEST. COLD AIR ADVECTION IN THE WAKE OF THIS SYSTEM WILL BOOST
MIXING DEPTHS AS THE SW GRADIENT TIGHTENS. THIS WILL LEAD TO A BRIEF
PERIOD OF GALE FORCE WIND GUSTS IN THE 21Z TO 03Z TIME FRAME /MOST
LIKELY ACROSS SAGINAW BAY OUT INTO CENTRAL LAKE HURON/. THE WINDS
WILL VEER TOWARD THE WEST-NORTHWEST DURING THE NIGHT WHILE WEAKENING

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
647 PM EST MON FEB 1 2016

.AVIATION...

VISIBLE SATELLITE IMAGERY HEADING INTO SUNSET INDICATED MBS AS THE
ONLY LOCATION SUBJECT TO LOW CLOUDS WITHOUT A DIURNAL COMPONENT AS
HIGH PRESSURE CONTINUES TO SLIDE ACROSS THE REGION DURING THE
EVENING. VEERING WIND AFTER MIDNIGHT COULD BRING SOME OF THOSE
CLOUDS SOUTHWARD TOWARD FNT AND POSSIBLY PTK. THIS WILL BE MONITORED
BEFORE GOING TOO PESSIMISTIC ON THE CEILING FORECAST. SLIGHTLY
COLDER AIR LEAKING IN FROM ONTARIO COULD ALSO ACTIVATE CLOUDS FROM
LAKES HURON AND ERIE...THE LATTER POSSIBLY MAKING IT INTO THE DTW
CORRIDOR TOWARD SUNRISE TUESDAY. THE OVERNIGHT CLOUD TRENDS FROM
LAKE HURON WILL BE ESPECIALLY IMPORTANT FOR CONDITIONS DURING THE
DAY AS BORDERLINE MVFR/VFR WILL BE POSSIBLE NORTH OF DTW AS THE LOW
LEVEL FLOW CONTINUES TO VEER AND STRENGTHEN AHEAD OF THE NEXT LOW
PRESSURE SYSTEM. THIS SYSTEM WILL SUPPORT MODERATE TO STRONG
EASTERLY WIND AND SPREAD RAIN OVER SE MICHIGAN DURING LATE AFTERNOON
WITH A BRIEF WINTRY MIX POSSIBLE AT MBS. ALL AREAS WILL SEE A RAPID
ONSET OF MVFR TO IFR WITH LOW LEVEL SATURATION INTO TUESDAY EVENING.

FOR DTW... LOW CLOUD POTENTIAL WILL CONTINUE TO BE MONITORED DURING
THE NIGHT AS EASTERLY LOW LEVEL FLOW DEVELOPS FROM LAKES HURON AND
ERIE. STRATUS/STRATOCU THAT BRUSHES THE TERMINAL WILL BE DIRECTED
NORTH DURING TUESDAY MORNING WITH MODERATE TO STRONG EASTERLY WIND
VEERING SLIGHTLY SOUTHEAST. VFR WILL THEN CONTINUE UNTIL RAPID ONSET
OF CEILING BELOW 5000 FT LATE TUESDAY AFTERNOON AS RAIN SPREADS INTO
THE REGION...THEN QUICKLY DOWN TO MVFR AND IFR EARLY TO MID TUESDAY
EVENING.

//DTW THRESHOLD PROBABILITIES...

* LOW FOR CEILING AOB 5 KFT THROUGH TUESDAY MORNING. HIGH TUESDAY
  AFTERNOON INTO EVENING.

* MODERATE FOR EASTERLY WIND EXCEEDING CROSS WIND POTENTIAL TUESDAY
  AFTERNOON.

DISCUSSION...

WEAK DEEP LAYER SUBSIDENCE AND DIMINISHED MOISTURE QUALITY WILL
DEFINE CONDITIONS LOCALLY OVER ROUGHLY THE NEXT 24 HOURS /INTO EARLY
TUESDAY AFTERNOON/...YIELDING A RELATIVE LULL IN ACTIVE WEATHER AS
ATTENTION TURNS TO THE SHARP MID LEVEL WAVE AND ATTENDANT UPPER JET
CORE NOW KICKING OUT OF THE SOUTHERN ROCKIES.  12Z MODEL SUITE
ARRIVING IN LINE WITH RECENT INTRAMODEL TRENDS AND GENERAL CONSENSUS
FOR THE EVENTUAL TRACK...STRENGTH AND TIMING OF THIS CLOSED SYSTEM
AS IT TRANSLATES THROUGH THE GREAT LAKES TUESDAY NIGHT AND
WEDNESDAY. STRONG SFC CYCLOGENESIS WILL COMMENCE BY TONIGHT AS THE
MAIN HEIGHT FALL CENTER KICKS EAST OF THE ROCKIES...WITH SUBSEQUENT
DEEPENING THROUGH EARLY TUESDAY AS THE SFC LOW LIFTS TO NEAR KANSAS
CITY.  PRONOUNCED DYNAMIC RESPONSE IMMEDIATELY DOWNSTREAM WILL NET A
ROBUST NORTHWARD THETA-E SURGE WITHIN THE EXPANDING FIELD OF LOW-MID
LEVEL WARM AIR ADVECTION/ISENTROPIC ASCENT AND UPPER DIFFLUENCE.
THIS DEEP MOISTURE PLUME WILL RAPIDLY EXPAND NORTHEAST INTO SE
MICHIGAN 21Z-01Z LATE TUESDAY...SETTING UP A SOLID PERIOD OF LGT-MDT
RAINFALL THROUGH EARLY TUESDAY NIGHT.

PTYPE CONCERNS AT ONSET LARGELY MITIGATED BY THE LATE DAY TIMING...A
SEEMINGLY LARGE ENOUGH DIURNAL TIMELINE DESPITE THE STUBBORN NEAR
SURFACE EASTERLY FLOW TO INCH SURFACE TEMPERATURES ABOVE FREEZING
ALL AREAS PRIOR TO ONSET. NARROW WINDOW FOR A BRIEF PERIOD OF
SNOW/SLEET ACROSS THE TRI-CITIES/THUMB AT ONSET AS EVAPORATIVE
COOLING PROCESSES TAKE HOLD AND WET BULB TEMPS HOVER AROUND
FREEZING. OTHERWISE...LOOKING AT A GOOD .3 TO .6" OF LIQUID QPF
GIVEN THE MOISTURE QUALITY AND BACKGROUND FORCING...WITHIN AN
INCREASINGLY UNSTABLE MID LEVEL ENVIRONMENT. PATTERN SUGGESTS A
WINDOW FOR SEEING A FEW RUMBLES OF THUNDER /22Z-04Z/ AS THE THETA-E
RIDGE PIVOTS ACROSS.  FIRM SOUTHEAST GRADIENT DOES CARRY 40+ KTS FOR
A TIME AT THE TOP OF THE STABLE LAYER /ABOVE 2000 FT/...TOO STABLE
BENEATH TO BE OF GREATER CONCERN BUT MAY YIELD SOME GUSTY WINDS
/30 MPH RANGE/.

ENCROACHING MID LEVEL DRY SLOT OF MATURING SYSTEM ARRIVING
COINCIDENT WITH THE LEAD COLD/OCCLUDED FRONTAL PASSAGE WILL STEADILY
