...WINDS TO GRADUALLY DIMINISH TODAY...

.THE STORM WARNING FOR CENTRAL LAKE HURON AND SAGINAW BAY WILL BE
ADJUSTED DOWN TO A GALE WARNING WITH THIS FORECAST ISSUANCE AND
EXTENDED THROUGH THURSDAY EVENING. THE POWERFUL LOW PRESSURE
SYSTEM NEAR THE WEST END OF LAKE ERIE WILL DRIFT TOWARD PORT HURON
AND WEAKEN THROUGH THE DAY AND THEN MOVE THROUGH ONTARIO INTO
QUEBEC TONIGHT. THIS WILL ALLOW REMAINING NORTHEAST WIND GUSTS TO
DROP FROM THE MID 40 KNOT RANGE DOWN TO AROUND 35 KNOTS DURING THE
AFTERNOON AS THE WIND DIRECTION TURNS TOWARD THE NORTHWEST. THE
RAINFALL PATTERN WILL ALSO WEAKEN WITH TIME THROUGH THE DAY
ALLOWING SOME IMPROVEMENT IN VISIBILITY AS THE NEAR 20 FOOT WAVE
PATTERN SUBSIDES TO 10 FEET OR LESS BY THIS EVENING. SMALL CRAFT
ADVISORIES WILL THEN LIKELY BE NEEDED FOR FRIDAY UNTIL THE WAVES
DROP BELOW 4 FEET BY FRIDAY EVENING. HIGH PRESSURE BUILDING INTO
THE OHIO VALLEY FRIDAY, COMBINED WITH A VERY WEAK TROUGH OVER THE
UPPER MIDWEST, WILL BRING MUCH IMPROVED MARINE CONDITIONS FOR THE
WEEKEND.

URGENT - MARINE WEATHER MESSAGE
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
923 AM EDT THU OCT 20 2011

...WINDS AND WAVES WILL GRADUALLY DECREASE THIS AFTERNOON AND TONIGHT...

.THE POWERFUL LOW PRESSURE SYSTEM NEAR THE WEST END OF LAKE ERIE
WILL DRIFT TOWARD PORT HURON AND WEAKEN THROUGH THE DAY AND THEN
MOVE THROUGH ONTARIO INTO QUEBEC TONIGHT. THIS WILL ALLOW
REMAINING NORTHEAST WIND GUSTS TO DROP FROM THE MID 40 KNOT RANGE
DOWN TO AROUND 35 KNOTS DURING THE AFTERNOON AS THE WIND DIRECTION
TURNS TOWARD THE NORTHWEST. THE RAINFALL PATTERN WILL ALSO WEAKEN
WITH TIME THROUGH THE DAY ALLOWING SOME IMPROVEMENT IN VISIBILITY
AS THE NEAR 20 FOOT WAVE PATTERN SUBSIDES TO 10 FEET OR LESS BY
THIS EVENING. SMALL CRAFT ADVISORIES WILL THEN LIKELY BE NEEDED
FOR FRIDAY UNTIL THE WAVES DROP BELOW 4 FEET BY FRIDAY EVENING.
HIGH PRESSURE BUILDING INTO THE OHIO VALLEY FRIDAY, COMBINED WITH
A VERY WEAK TROUGH OVER THE UPPER MIDWEST, WILL BRING MUCH
IMPROVED MARINE CONDITIONS FOR THE WEEKEND.

AREA FORECAST DISCUSSION

738 PM EDT TUE OCT 18 2011

.AVIATION...

//DISCUSSION...

WEAK MOISTURE TRANSPORT EVOLVING NORTHWEST OF AN ORGANIZING LOW
PRESSURE SYSTEM OVER THE TENNESSEE VALLEY WILL SLIDE ACROSS
SOUTHEAST MICHIGAN TONIGHT.  THIS WILL BRING LOWER VFR/MVFR
CONDITIONS IN INTERMITTENT LIGHT RAIN AT ALL TERMINALS THROUGH THE
EARLY MORNING HOURS.  RAINFALL WILL INCREASE IN COVERAGE AND
INTENSITY THROUGH THE LATTER HALF OF THE MORNING AND INTO THE
AFTERNOON AS THE LOW LIFTS NORTHWARD AND STRENGTHENS.  THIS WILL
ALLOW CONDITIONS TO MAINTAIN LOWER MVFR/IFR CIGS AND VISIBILITY.
WINDS WILL INCREASE OUT OF THE NORTHEAST THROUGH THE PERIOD...
BECOMING GUSTY ON WEDNESDAY. GUSTS 25 TO 30 KNOTS LOOK ATTAINABLE
AT ALL TERMINALS BY THE AFTERNOON...WITH THE POTENTIAL FOR
LOCALIZED HIGHER GUSTS AT MBS WITH WINDS COMING OFF SAGINAW BAY.

FOR DTW...NORTHEAST WINDS WILL INCREASE TO 15-20 KNOTS SUSTAINED
WEDNESDAY AFTERNOON.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE THAT CEILINGS WILL DROP BELOW 5000 FEET AFTER 04Z
  TONIGHT...THEN REMAIN BELOW 5000 FEET THROUGH WEDNESDAY.

* HIGH CONFIDENCE FOR SUSTAINED NORTHEAST WINDS OF 15 TO 20 KNOTS
  WITH GUSTS AROUND 25 KNOTS FROM A 030-050 DIRECTION WEDNESDAY
  AFTERNOON.

&&

.PREV DISCUSSION...ISSUED 406 PM EDT TUE OCT 18 2011

SHORT TERM...THIS AFTERNOON AND TONIGHT

A STRONG LOW PRESSURE SYSTEM DEVELOPING OVER THE OHIO VALLEY WILL
CONTINUE TO PUMP MOISTURE INTO THE SOUTHERN GREAT LAKES LATE THIS
AFTERNOON AND THIS EVENING AS THE LOW ORGANIZES AND DEEPENS. THE
DEEPENING LOW WILL CAUSE THE PRESSURE GRADIENT TO TIGHTEN DURING THE
OVERNIGHT HOURS...WITH GUSTY WINDS DEVELOPING AFTER MIDNIGHT. THE
INFLUX OF MOISTURE...AS EVIDENCED BY THE THICKENING CLOUD FIELD THIS
AFTERNOON...WILL COMBINE WITH A GOOD AMOUNT OF ISENTROPIC LIFT AND
FGEN FORCING NORTH OF AN APPROACHING WARM FRONT TO BRING WIDESPREAD
RAIN SHOWERS TO SOUTHEAST MICHIGAN TONIGHT. THE FORCING AND MOISTURE
WILL HAVE A FAIR AMOUNT OF LOW LEVEL DRY AIR TO OVERCOME BEFORE RAIN
HITS THE GROUND...PER THE 12Z KDTX RAOB SOUNDING...HOWEVER THE
MOISTURE ADVECTING IN IS QUITE DEEP AND THE FORCING SUFFICIENT
ENOUGH TO OVERCOME THE LOW LEVEL DRY AIR AT SOME POINT TONIGHT.
GIVEN A BETTER HANDLE ON THE START TIME OF THE RAIN WILL ADJUST THE
POP GRIDS TONIGHT TO REFLECT THE DEVELOPMENT OF THE RAIN SHOWERS
FROM SOUTH TO NORTH AS THIS DRY AIR IS OVERCOME.

WITH A FAIR AMOUNT OF CLOUD COVER PREVENTING MUCH IN THE WAY OF
RADIATIONAL COOLING LOW TEMPERATURES ARE ONLY EXPECTED TO DIP DOWN
IN THE 40S DURING THE OVERNIGHT HOURS.

LONG TERM...WEDNESDAY THROUGH NEXT TUESDAY

LONG TERM FORECAST WILL FOCUS ON THE POWERFUL LOW PRESSURE SYSTEM
THAT WILL IMPACT THE OHIO VALLEY AND GREAT LAKES REGION TOMORROW
INTO THURSDAY. FEATURE OF INTEREST IS CURRENTLY SEEN NICELY ON WATER
VAPOR IMAGERY OVER THE MID MISSISSIPPI VALLEY. LIGHT PRECIP WILL BE
ONGOING AT THE START OF THE PERIOD IN RESPONSE TO INCREASING WARM
AIR ADVECTION/ISENTROPIC ASCENT. SURFACE LOW PRESSURE WILL CONTINUE
TO DEEPEN TOMORROW AS A 130+ KNOT JET STREAK ROUNDS THE BASE OF THE
TROUGH AND MID LEVEL HEIGHTS CONTINUE TO FALL. SEVERAL FACTORS WILL
COME TOGETHER TO SUPPORT AN INCREASE IN THE RAINFALL RATE AS WE HEAD
INTO TOMORROW EVENING. IMPRESSIVE PV ANOMALY WILL APPROACH THE AREA
BY 00Z-06Z TOMORROW NIGHT ALONG WITH LEFT EXIT REGION OF 250MB JET.
AS THE LOW CONTINUES TO STRENGTHEN...A DECENT TROWAL WILL SET UP
OVER SOUTHEAST MICHIGAN. WARM AIR ADVECTION WILL INCREASE
SUBSTANTIALLY AROUND 00Z WITH IMPRESSIVE 300K ISENTROPIC ASCENT AND
ASSOCIATED 700MB OMEGA VALUES. LOW LEVEL 850-700MB FGEN WILL ALSO
INCREASE SUBSTANTIALLY AROUND 00Z IN RESPONSE TO INCREASING
CONVERGENCE AND TIGHTENING THERMAL GRADIENT.

ALL OF THIS WILL ALSO COINCIDE WITH THE BEST SURGE OF MOISTURE AS
PWAT VALUES INCREASE TO AROUND 1.25 INCHES. LATEST 12Z MODELS
CONTINUED THE TREND OF SHUNTING THE BEST TROPICAL MOISTURE EAST OF
THE REGION THANKS TO RIGHT EXIT REGION DYNAMICS OF 250MB JET. NAM
AND GFS BUFR SOUNDINGS ALSO SHOW MIDLEVEL LAPSE RATES REMAINING
FAIRLY STABLE...MOIST ADIABATIC AT BEST. THAT BEING SAID...STILL
PLENTY OF DYNAMIC FORCING AND AVAILABLE MOISTURE TO SUPPORT A TOTAL
OF 1-2 INCHES OF RAIN BY 06Z THURSDAY MORNING WITH THE HEAVIEST RAIN
OCCURRING 21Z-03Z. OTHER POTENTIAL LIMITING FACTOR WILL BE THE EVER
VEXING DRY SLOT. LATEST 12Z MODELS ARE IN FAIRLY GOOD AGREEMENT IN
SHOWING THE DRY SLOT STAYING JUST EAST OF OUR AREA BUT A SLIGHT
WESTWARD SHIFT IN THE TRACK COULD LIMIT QPF TOTALS OVER THE
SOUTHEASTERN CWA. GIVEN SOME LINGERING UNCERTAINTY AND THE FACT THAT
THE HEAVIEST RAIN/POTENTIAL FLOODING IS STILL 24+ HOURS AWAY...WILL
LET LATER SHIFTS CONSIDER POSSIBLE FLOOD WATCH.

LOW PRESSURE SYSTEM WILL BEGIN TO QUICKLY FILL ON THURSDAY MORNING.
FORCING FOR PRECIP WILL BE LIMITED TO LINGERING DEFORMATION BUT
COULD GENERATE ANOTHER 0.25-0.5 INCH OF RAIN. THE EXACT LOCATION
WILL DEPEND ON HOW FAR WEST THE DRY SLOT MOVES WITH THE BEST CHANCE
FOR PERSISTENT RAIN OVER THE NORTH AND WEST. OTHER MAIN STORY DURING
THIS EVENT WILL BE STRONG WINDS. STRONG PRESSURE GRADIENT FROM THE
986MB SURFACE LOW WILL DEVELOP TOMORROW AFTERNOON. STABLE PROFILE
ABOVE 925MB WILL LIMIT MIXING POTENTIAL BUT STILL EXPECT WIND GUSTS
OF 30-40 MPH WITH THE STRONGER GUSTS OVER THE NORTHERN CWA. ONE
POSITIVE ASPECT OF THE STRONGER/FARTHER WEST SOLUTION THAT WE HAVE
TRENDED TOWARD WILL BE SLIGHTLY WARMER TEMPERATURES. WITH THE
SURFACE LOW TRACKING DIRECTLY OVER US...THE COLDEST AIR WILL NOT BE
ABLE TO FULLY IMPACT SOUTHEAST MICHIGAN. MOS GUIDANCE GIVES MAX
TEMPS TOMORROW IN THE MID TO UPPER 50S AND THIS SEEMS REASONABLE
GIVEN THE TRACK OF THE LOW. TEMPS ON THURSDAY WILL BE SOMEWHAT
COOLER DUE TO DEVELOPING NORTHERLY FLOW BUT STILL IN THE LOW TO MID
50S.

FRIDAY AND BEYOND...LOW PRESSURE WILL QUICKLY EXIT THE REGION FRIDAY
MORNING WITH DRY AIR AND SUBSIDENCE BUILDING ACROSS THE GREAT LAKES.
AFTER ONE MORE COOL DAY ON FRIDAY...EXPECT A SLOWLY MODERATING TREND
IN TEMPS FOR THE WEEKEND AND EARLY NEXT WEEK WITH WESTERLY FLOW
DEVELOPING. A WEAK COLD FRONT WILL CROSS THE REGION ON SUNDAY WITH A
LOW CHANCE OF A FEW SCATTERED SHOWERS. THIS FRONT WILL DO LITTLE TO
DROP TEMPERATURES THOUGH AS SOUTHWESTERLY FLOW AND MIDLEVEL RIDGING
WILL QUICKLY DEVELOP ON MONDAY AND PUSH TEMPS EVEN HIGHER.

MARINE...

A STRONG LOW PRESSURE SYSTEM DEVELOPING OVER THE OHIO VALLEY TONIGHT
WILL HEAD NORTHWARD TOWARDS THE SOUTHERN GREAT LAKES
WEDNESDAY...THEN SLOWLY TRACK THROUGH THE CENTRAL GREAT LAKES
THURSDAY AND THURSDAY NIGHT. WINDS WILL QUICKLY INCREASE LATE
TONIGHT AND WEDNESDAY...BRINGING STORM AND GALE FORCE WINDS TO THE
CENTRAL GREAT LAKES.  STORM FORCE WIND GUSTS WILL BE POSSIBLE ON THE
NORTH HALF OF LAKE HURON LATE WEDNESDAY INTO EARLY THURSDAY WITH A
STRONG GALE POSSIBLE OVER SOUTH SECTIONS THROUGH SAGINAW BAY. LOW
VISIBILITY IN HEAVY RAINFALL WILL ALSO BE A CONCERN OVER ALL MARINE
AREAS. THE TRACK OF THE SURFACE LOW FROM ABOUT TOLEDO TO WINDSOR TO
TORONTO IS EXPECTED TO RESULT IN WINDS BELOW GALE FORCE FOR LAKE ST
CLAIR AND WESTERN LAKE ERIE. THE STRONG WIND CONDITIONS ARE THEN
EXPECTED TO IMPROVE THURSDAY NIGHT INTO FRIDAY AS THIS LOW PRESSURE
SYSTEM TRACKS INTO QUEBEC. PREVIOUS HEADLINES ARE STILL IN
PLACE...HOWEVER THE TIMING HAS BEEN DELAYED BY A COUPLE OF HOURS
GIVEN A SLIGHT DELAY IN THE HAZARDOUS CONDITIONS. SINCE THE
