URGENT - MARINE WEATHER MESSAGE
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
411 AM EST FRI MAR 9 2012

...A NORTHWEST GALE THIS MORNING THROUGH THIS AFTERNOON...

.A STRONG PRESSURE GRADIENT IN ADVANCE OF HIGH PRESSURE CENTERED
OVER THE UPPER MISSISSIPPI VALLEY WILL STRENGTHEN MARKEDLY THIS
AFTERNOON AS A SURFACE TROUGH SLIDES ACROSS LAKE HURON. AS THIS
HAPPENS...BREEZY NORTHWEST FLOW OVER LAKE HURON WILL QUICKLY RAMP
UP DURING THE MORNING. MODERATE WINDS WILL GUST TO GALE FORCE
ACROSS THE NORTHERN HALF OF THE LAKE WITH A PERIOD OF STRONG GALES
POSSIBLE FOR CENTRAL LAKE HURON DURING THE MID DAY PERIOD WHEN
WAVE HEIGHTS WILL INCREASE TO WELL OVER 10 FEET. THEREFORE...THE
GALE WARNING REMAINS IN EFFECT FOR THE NORTHERN HALF OF LAKE
HURON. AN ADDITION HAS BEEN MADE TO THE SOUTHERN EXTENT OF THE
WARNING...WHERE THE OPEN WATERS FROM PORT AUSTIN TO HARBOR BEACH
HAVE BEEN ADDED. FOR THIS AREA...THE NORTHWEST FETCH IS EXPECTED
TO BE SUFFICIENT TO SUPPORT GALES OVER MOST OR ALL OF THE ZONE.
DEPENDING ON THE EXACT TRACK OF THE LOW...THE WARNING COULD
POTENTIALLY BE FURTHER EXPANDED TO INCLUDE NEARSHORE AREAS NEAR
THE TIP OF THE THUMB. IN ADDITION TO BREEZY CONDITIONS FOR THE
NEARSHORE ZONES...WAVES OF 5 FEET OR HIGHER EMANATING FROM TODAY'S
GALE WILL ENSURE CHOPPY WATERS FOR THE SOUTHERN HALF OF LAKE HURON
TONIGHT EVEN AFTER WINDS SUBSIDE. HIGH PRESSURE WILL THEN QUICKLY
ADVANCE TO THE EAST COAST ON SATURDAY WITH INCREASING
SOUTHWESTERLY WINDS ON THE BACK SIDE OF THE HIGH IMPACTING THE
GREAT LAKES REGION. THESE WINDS MAY BECOME QUITE STRONG ON
SATURDAY BEFORE STRONG LOW LEVEL WARMING SUBSTANTIALLY INCREASES
THE STABILITY OVER THE LAKES SATURDAY NIGHT.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
320 PM EST THU MAR 8 2012

.SHORT TERM... THIS EVENING AND TONIGHT

ONGOING COLD AIR ADVECTION WILL CONTINUE TO CAUSE TEMPS TO DROP
THROUGH THE 30S DURING THE COURSE OF THE EVENING. MOISTURE FLUX OFF
LAKE MICHIGAN UNDER THE COLD WESTERLY FLOW AND STEEP LOW LEVEL LAPSE
RATES HAS LED TO SOME LIGHT RAIN AND SNOW SHOWERS THIS AFTERNOON. A
DRIER LOW LEVEL AIRMASS IS IN THE PROCESS OF ADVECTING INTO SRN MI
FROM WISCONSIN AS EVIDENT BY SFC DEWPOINTS IN THE TEENS UPSTREAM OF
LAKE MI AND A DECREASING STRATO CU FIELD OVER SW LOWER MI. THIS WILL
END ANY LINGERING SHOWERS BY EARLY EVENING AND WILL LEAD TO AN
OVERALL CLEARING TREND.

ATTENTION THEN TURNS TO THE MID LEVEL WAVE NOW DROPPING INTO NRN
MN...FORECAST TO TRACK ACROSS LOWER MI OVERNIGHT. THE WAVE ITSELF IS
FORECAST TO BECOME HIGHLY SHEARED AS IT DIVES INTO THE BASE OF THE
LONG WAVE TROUGH AXIS OVER THE SRN GREAT LAKES. ALTHOUGH BRIEF...A
PERIOD OF DECENT DCVA ASSOCIATED WITH THIS WAVE IS FORECAST TO
TARGET CENTRAL AND NORTHERN LOWER MI OVERNIGHT. THE HIGHEST CHANCES
FOR SNOW CONTINUE TO BE ACROSS THE SAGINAW VALLEY AND THUMB REGION
WHERE BETTER LARGE SCALE ASCENT AND DEEPER MOISTURE WILL BE PRESENT.
THE SHORT DURATION OF LIFT /3 HOURS OR LESS/ WILL SUPPORT MINOR SNOW
ACCUMS ACROSS THE SAGINAW VALLEY AND THUMB /LESS THAN AN INCH/.
MODEL SOUNDINGS DO HOWEVER SHOW STEEP SFC-700MB LAPSE RATES TONIGHT
/NEAR 8C PER KM/. THE ADDED CONVECTIVE COMPONENT MAY LEAD TO SOME
LOCALLY HIGHER AMOUNTS. ALTHOUGH THE AIRMASS WILL BE MUCH DRIER
FARTHER SOUTH...THERE DOES APPEAR TO BE THE POTENTIAL FOR A BRIEF
INCREASE IN LAKE ENHANCEMENT OFF LAKE MICHIGAN LATE TONIGHT AS COLD
AIR ADVECTION LIFTS EQUILIBRIUM LEVELS. THIS WILL SUPPORT SOME
SCATTERED SNOW SHOWERS OR FLURRIES ACROSS THE SOUTHERN HALF OF THE
FORECAST AREA...WITH LITTLE IN THE WAY OF ACCUMS EXPECTED. THE
SURFACE LOW ASSOCIATED WITH THIS UPPER WAVE IS FORECAST TO TRACK
INTO LAKE HURON LATE TONIGHT...WHICH WILL TIGHTEN THE GRADIENT OVER
SRN MI. THIS ALONG WITH THE STEEP LOW LEVEL LAPSE RATES WILL CAUSE
AN INCREASE IN WINDS LATE TONIGHT...POSSIBLY GUSTING UP TO 30 MPH AT
TIMES. AFTER A BRIEF PERIOD OF CLEARING LATE THIS EVENING...THE
INCREASED GRADIENT OVERNIGHT SHOULD KEEP MINS IN THE UPPER 20S/LOWER
30S.

&&

.LONG TERM...FRIDAY THROUGH NEXT THURSDAY

A WEAK SHORTWAVE OVER NORTHERN MICHIGAN WILL EXIT TO ONTARIO DURING
THE DAY ON FRIDAY MAKING WAY FOR HIGH PRESSURE TO BUILD ACROSS SE MI
THROUGH SUNDAY AFTERNOON.

THE NEXT SURFACE LOW WILL LIFT OUT OF THE SOUTHERN PLAINS REACHING
THE GREAT LAKES SUNDAY NIGHT. A CUT OFF UPPER LOW OVER THE SW CONUS
WILL SLOWLY DRIFT EAST AND NORTH THROUGH THE WEEKEND AS IT
GRADUALLY GETS ABSORBED BACK INTO THE MAIN FLOW. PREVIOUS FORECASTER
HELD OFF ON THE ONSET OF PRECIP AS MODELS TEND TO BE TOO FAST WITH
CLOSED LOWS. LATEST MODEL RUNS ARE COMING BETTER IN LINE WITH THE
GOING FORECAST SLOWING IT DOWN NOW AS WELL. THE ECMWF SHOWS THE SFC
LOW BRIEFLY DEEPENING DURING ITS PASSAGE ACROSS MI. THE 12Z GFS HAS
THE LOW DEEPENING BUT ON A MORE NORTHERLY TRACK ACROSS THE WESTERN
GREAT LAKES TRYING TO PHASE IT WITH THE LARGER DOMINATE CANADIAN LOW
OVER THE HUDSON BAY. THE TIMING OF THE PRECIP WILL BE FROM SUNDAY
NIGHT THROUGH MONDAY EVENING WITH THE HEAVIEST RAIN FALLING MONDAY
MORNING AS THE COLD FRONT APPROACHES WITH GOOD MID LEVEL DIFFLUENT
FLOW AND A WEAK JET MAX PASSING OVER. IN ADDITION...A GOOD SURGE OF
700MB THETA E MOVES INTO SOUTHERN MICHIGAN SUNDAY NIGHT BEHIND THE
WARM FRONT. ALL THAT SAID...WILL CONTINUE THE DRY FORECAST FOR
SUNDAY AS THE COLUMN WILL BE VERY DRY EARLY WITH INCREASING MOISTURE
THROUGH THE EVENING. PRECIP WILL END QUICKLY AFTER THE COLD FRONT
PASSES AS MUCH DRIER AIR ADVECTS INTO THE REGION. ONLY POSSIBLY
CONCERN WOULD BE FOR MORE OF A ECMWF TRACK WHICH WOULD KEEP THE WRAP
AROUND MOISTURE OVER THE NORTHERN CWA THROUGHOUT THE DAY MONDAY.

POTENTIAL EXISTS FOR PRECIP TO SCATTER OUT EARLIER ON MONDAY IF
SIGNATURES IN THE MODELS COME TO FRUITION. AS IS SOMETIMES THE
CASE...THE SYSTEM ENERGY SPLITS WHERE THE BULK OF IT STAYS CLOSELY
TIED TO THE LOW PRESSURE CENTER AND THE OTHER AREA OF ENERGY DIVES
SOUTHEASTWARD ALONG THE COLD FRONT AS IT SEARCHES FOR BETTER
MOISTURE AND INSTABILITY. THIS CAN LEAVE AN AREA WHICH SCATTERS OUT
IN BETWEEN WHICH COULD FALL OVER SE MI. A BIT TOO EARLY TO CALL IT
NOW BUT SOMETHING TO KEEP AN EYE ON AS IT APPROACHES. HIGH PRESSURE
WILL BUILD IN MONDAY NIGHT LASTING THROUGH MID WEEK WHEN ANOTHER
COLD FRONT LOOKS TO PASS THROUGH THE GREAT LAKES.

TEMPS WILL BE MILD FOR MUCH OF THE EXTENDED WITH THE EXCEPTION OF
FRIDAY WHEN WE WILL FALL SHORT OF REACHING 40 DEGREES. WARM AIR WILL
FILL BACK IN ON SATURDAY WITH HIGH PRESSURE AND WITH THE JET STREAM
OVER THE BORDER OF THE US/CANADA...WARM AIR WILL BUILD NORTHWARD
AND LINGER THROUGH THE END OF NEXT WEEK.

&&

.MARINE...

LOW PRESSURE WILL TRACK FROM NORTHWEST ONTARIO TO LAKE HURON
TONIGHT...THEN WILL SLIDE ACROSS THE EASTERN GREAT LAKES FRIDAY
AFTERNOON. A TIGHTENING OF THE PRESSURE GRADIENT WILL OCCUR ON THE
BACK SIDE OF THIS DEPARTING LOW. THIS ALONG WITH A REINFORCEMENT OF
COLD AIR OVER THE LAKES WILL LEAD TO INCREASING WINDS LATE TONIGHT
AND THROUGH THE DAY ON FRIDAY...SUPPORTING GALES ON LAKE HURON AND
SMALL CRAFT ADVISORIES IN THE NEARSHORE WATERS. WINDS AND WAVES WILL
SUBSIDE FRIDAY NIGHT AS STRONG HIGH PRESSURE MOVES ACROSS THE
REGION. THE HIGH WILL THEN QUICKLY ADVANCE TO THE EAST COAST ON
SATURDAY WITH INCREASING SOUTHWESTERLY WINDS ON THE BACK SIDE OF THE
HIGH IMPACTING THE GREAT LAKES REGION. THESE WINDS MAY BECOME QUITE
STRONG ON SATURDAY BEFORE STRONG LOW LEVEL WARMING SUBSTANTIALLY
INCREASES THE STABILITY OVER THE LAKES SATURDAY NIGHT.

&&

.AVIATION...ISSUED 1156 AM EST THU MAR 8 2012

//DISCUSSION...

THE COLD FRONT HAS NOW PUSHED EAST OF METRO DETROIT. RESIDUAL POST
FRONTAL LOW LEVEL MOISTURE WILL MAINTAIN CEILINGS IN THE 1500 TO
2500 FT RANGE FOR AT LEAST THE NEXT TWO TO THREE HOURS. DRIER AIR
WILL CONTINUE TO PUSH IN FROM THE WEST...WHICH WOULD LIFT CEILINGS
ABOVE 3000 FT IN THE 20-22Z TIME FRAME AND WILL LIKELY SCATTERED THE
LOW CLOUDS OUT THIS EVENING. A FAST MOVING LOW PRESSURE SYSTEM WILL
TRACK ACROSS LAKE HURON LATE TONIGHT INTO FRI MORNING. THIS SYSTEM
WILL INCREASE LOW CLOUDS DURING THE OVERNIGHT AND SHOULD LEAD TO AT
LEAST SOME LIGHT SNOW NORTH OF PTK.

FOR DTW....THE BACK EDGE OF THE POST FRONTAL RAIN SHOULD MOVE EAST
OF THE AIRFIELD BETWEEN 18Z AND 19Z. THE WINDS HAVE ALREADY VEERED
TO THE WEST AND SHOULD CONTINUE TO GUST UP AROUND 25KTS OVER THE
NEXT ONE TO TWO HOURS.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN CEILINGS REMAINING BELOW 5000 FT THROUGH 22Z.
