REMAINING BETWEEN 15 AND 25 KNOTS ACROSS MUCH OF LAKE HURON. THE 
PASSAGE OF ANOTHER LOW PRESSURE SYSTEM ACROSS ONTARIO COMBINED WITH 
STRONG HIGH PRESSURE OVER THE OHIO VALLEY WILL THEN PROVIDE A TIGHT 
SURFACE PRESSURE GRADIENT OVER THE CENTRAL GREAT LAKES ON MONDAY. 
SOUTHWESTERLY WINDS WILL INCREASE TO AT LEAST 20 KNOTS ACROSS ALL 
MARINE AREAS...AND POTENTIALLY REACH GALE FORCE ACROSS PORTIONS OF 
LAKE HURON. A GALE WATCH IS IN EFFECT FOR MUCH OF LAKE HURON...AND

THE AREA. WINDS WILL GRADUALLY DECREASE LATE MONDAY NIGHT AND

353 AM EDT MON SEP 24 2012

...GALE FORCE WINDS TODAY INTO TONIGHT...

.A COLD FRONT WILL PUSH SOUTH ACROSS LAKE SUPERIOR THIS 
AFTERNOON...THEN INTO NORTHERN LAKE HURON TONIGHT. AN INCREASING SW 
GRADIENT WILL OCCUR AS THIS COLD FRONT PUSHES SOUTH...EVIDENCED BY 
THE INCREASING WINDS NOW BEING OBSERVED ACROSS LAKE SUPERIOR. 
LINGERING COLD AIR OVER THE RELATIVELY WARM WATER WILL LEAD TO 
UNSTABLE CONDITIONS ACROSS THE LAKES WELL INTO THE AFTERNOON. THIS 
WILL BE SUPPORTIVE OF GALES ON LAKE HURON AND SMALL CRAFT ADVISORY 
CONDITIONS ON LAKE ST CLAIR AND WESTERN LAKE ERIE. DESPITE A 
TIGHTENING OF THE SFC GRADIENT OVER SOUTHERN LAKE HURON TONIGHT AS 
THE COLD FRONT PUSHES SOUTH...LOW LEVEL WARM AIR ADVECTION WILL 
INCREASE THE OVER LAKE STABILITY AND THUS MAKE IT MORE DIFFICULT TO 
MIX THE GALE FORCE WINDS TO THE LAKE SURFACE...ESPECIALLY AFTER 
MIDNIGHT. THE COLD FRONT WILL ACTUALLY SLOW DOWN CONSIDERABLY 
TONIGHT AND IS NOT FORECAST TO PUSH THROUGH THE SOUTHERN LAKE HURON 
BASIN UNTIL LATE TUESDAY NIGHT. THE PASSAGE OF THIS FRONT WILL BE 
MARKED BY A VEERING OF THE WINDS TO THE NORTH. THE WINDS WILL 
ACTUALLY WEAKEN FOLLOWING THE PASSAGE OF THE FRONT. STRONG HIGH 
PRESSURE WILL THEN BUILD IN FROM THE NORTHWEST ON 
WEDNESDAY...LEADING TO FAIRLY LIGHT WINDS THROUGH THE REST OF THE 
WEEK.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
417 AM EDT SAT SEP 22 2012

.SHORT TERM...TODAY AND TONIGHT

CONDITIONS WILL FEEL VERY FALL-LIKE TODAY AS THE SEASON OFFICIALLY
STARTS...AS VERY COOL TEMPERATURES...SOME RAIN SHOWERS...AND GUSTY
WINDS OCCUR TODAY.

WATER VAPOR IMAGERY CONTINUES TO SHOW SEVERAL EMBEDDED SHORTWAVES
STREAMING THROUGH A MEAN TROUGH IN PLACE OVER THE GREAT LAKES. A FEW
WEAKER WAVES WERE MOVING THROUGH LOWER MICHIGAN AT 330AM...AND WERE
HELPING TO GENERATE SHOWERS AND EVEN A FEW THUNDERSTORMS OVER THE
WESTERN PART OF THE STATE. THESE SHOWERS SHOULD MOVE ACROSS THE AREA
BY 800 AM...AT WHICH TIME SUBSIDENCE BEHIND THE WAVES SHOULD PROVIDE
QUIETER CONDITIONS UNTIL ANOTHER UPPER WAVE APPROACHES DURING THE
VERY LATE MORNING AND AFTERNOON.

NEXT UPPER WAVE TO AFFECT LOWER MICHIGAN IS CURRENTLY SPINNING DOWN
THE MINNESOTA/WISCONSIN BORDER. THIS WAVE IS FORECAST TO TRACK ALONG
THE MICHIGAN/INDIANA/OHIO BORDER TODAY. AREA OF LOW/MID LEVEL
DEFORMATION AND FGEN WILL BRUSH ACROSS FAR SOUTHERN LOWER MICHIGAN
THIS AFTERNOON AND EARLY EVENING...PROVIDING A GOOD CHANCE OF RAIN
SOUTH OF M-59. FOR THE REMAINDER OF THE AREA...GOOD POTENTIAL FOR
SHOWERS ALSO EXISTS AS DIURNAL SURFACE HEATING AND COLDER AIR
ADVECTION ALOFT STEEPENS LOW-LEVEL LAPSE RATES TO AROUND 9 DEG C/KG.
THE COLDER AIR AND CYCLONIC FLOW OVER THE WARMER GREAT LAKES WILL
ALSO GENERATE A GOOD DEAL OF INSTABILITY...AND WILL GET LAKE EFFECT
PROCESSES GOING. A FEW THUNDERSTORMS WILL ALSO BE POSSIBLE...AS MU
CAPE VALUES RISE TO ALMOST 800 J/KG. THUNDERSTORMS WILL HOWEVER BE
MORE LIKELY OVER THE WESTERN PORTION OF THE STATE...CLOSER TO FLOW
OFF LAKE MICHIGAN. GOOD POTENTIAL FOR SMALL HAIL TO OCCUR WITH ANY
SHOWERS OR THUNDERSTORMS ALSO EXISTS TODAY AS FREEZING LEVELS HOVER
AROUND ONLY 5000 FEET.

COLD AIR IN PLACE OVER THE AREA AND CLOUD COVER WILL ONLY ALLOW MAX
TEMPERATURES TODAY TO WARM INTO THE MID 50S TO LOW 60S. LOWS TONIGHT
SHOULD FALL TO THE MID/UPPER 30S TO LOW 40S.

SHOWERS WILL DECREASE IN COVERAGE OVER THE INLAND AREAS OVERNIGHT AS
LAPSE RATES STABILIZE A LITTLE WITH THE LOSS OF DAYTIME HEATING AND
DRIER AIR WORKS INTO THE AREA.

&&

.LONG TERM...SUNDAY THROUGH FRIDAY

THE COLD AIR NOW POSITIONED ACROSS NRN MN AND NW ONTARIO WILL BECOME
CENTERED OVER LOWER MI BY SUN MORNING. WHILE THE GREAT LAKES WILL
MODIFY THIS AIRMASS...850MB TEMPS ARE STILL EXPECTED TO HOVER AROUND
0C THROUGH THE DAY. THE DEPTH OF LOW LEVEL COLD AIR WILL LEAD TO
STEEP LAPSE RATES FROM THE SFC TO 700MB...WHICH WILL ALLOW A FAIRLY
EXTENSIVE STRATO CU FIELD TO DEVELOP BY SUN AFTERNOON WITH ADDED
MOISTURE FLUX OFF LAKE MICHIGAN. THIS WILL KEEP DAYTIME HIGHS
SUPPRESSED TO THE 50S FOR MOST OF THE AREA. THE NAM SOLUTION IS A
BIT MORE AGRESSIVE WITH SUBSIDENCE FOLLOWING IN THE WAKE OF A MID
LEVEL WAVE SLIDING ACROSS LAKE HURON EARLY IN THE MORNING. AS A
RESULT...IT INDICATES A STRONG MID LEVEL INVERSION WHICH WOULD
DRASTICALLY LIMIT CONVECTIVE CLOUD DEPTHS. THE REMAINDER OF THE 00Z
MODEL SUITE HOWEVER INDICATE SOME ADDITIONAL MID LEVEL IMPULSES
ROLLING ACROSS THE STATE SUN AFTERNOON WHICH SUPPORT A HIGHER AND
WEAKER INVERSION AND THUS REMAIN SUPPORTIVE OF A LOW CHANCE OF SOME
SHOWERS /MAINLY DIURNALLY DRIVEN/.

THERE REMAINS STRONG AGREEMENT AMONG RECENT MODEL SOLUTIONS IN
SHOWING THE LONG WAVE TROUGH AXIS MOVING ACROSS NEW ENGLAND ON
MONDAY AS THE UPPER LOW LIFTS INTO NRN QUEBEC. THIS WILL LEAD TO
SUBSTANTIAL MID LEVEL HEIGHT RISES ACROSS SRN MI. MEANWHILE...A COLD
FRONT WILL PUSH SOUTH INTO THE NRN GREAT LAKES MONDAY...DRIVEN BY
YET ANOTHER MID LEVEL WAVE ROTATING AROUND THE ERN CANADIAN VORTEX.
WITH STRONG SFC HIGH PRESSURE LOCATED OVER THE OH AND TN
VALLEYS...LOW LEVEL W-SW FLOW WILL STRENGTHEN OVER THE AREA ON
MONDAY...LEADING TO A PUSH OF LOW LEVEL WARM AIR. THIS WILL RESULT
IN HIGHS REBOUNDING INTO THE 60S ON MON AND POSSIBLY 70S ON TUES.
PASSAGE OF THE COLD FRONT ACROSS THE FORECAST AREA WILL OCCUR EITHER
LATE TUES OR TUES NIGHT PER 00Z MODEL CONSENSUS. THERE IS EXPECTED
TO BE SOME GOOD UPPER JET DYNAMICS. THE MAIN ISSUE IN WHICH THE
MODEL SOLUTIONS ARE STRUGGLING WITH IS WITH RESPECT TO HOW AGRESSIVE
MOISTURE TRANSPORT INTO SE MI WILL BE. THE POTENTIAL FOR CONVECTIVE
DEVELOPMENT ACROSS THE OH AND MS VALLEYS SUGGESTS MOISTURE MAY
STRUGGLE TO ADVANCE THIS FAR NORTHWARD AND SUPPORTS A 20 OR 30 PCT
CHANCE OF SHOWERS TUES/TUES NIGHT ATTM.

CANADIAN HIGH PRESSURE WILL BUILD INTO THE REGION BY MID WEEK IN THE
WAKE OF THIS COLD FRONT. DESPITE RISING MID LEVEL HEIGHTS ACROSS THE
GREAT LAKES...THE POST FRONTAL SHALLOW COLD AIR IS EXPECTED TO KEEP
TEMPS ON THE COOL SIDE OF SEASONAL NORMS WED INTO THURS BEFORE THE
AIRMASS MODIFIES TOWARD THE END OF THE FORECAST PERIOD.

&&

.MARINE...

LOW PRESSURE WILL STRENGTHEN AS IT LIFTS FROM THE CENTRAL GREAT
LAKES UP INTO QUEBEC TODAY AND TONIGHT. A TIGHTENING SURFACE
PRESSURE GRADIENT BEHIND THIS AREA OF LOW PRESSURE IN COMBINATION
WITH STRONG COLD AIR ADVECTION OVER THE WARMER WATERS WILL ALLOW
WIND GUSTS AND WAVES TO INCREASE THIS AFTERNOON. NORTHWEST WINDS
OVER THE OPEN WATERS OF CENTRAL AND NORTHERN LAKE HURON ARE EXPECTED
TO GUST JUST OVER 30 KNOTS...WITH GUSTS TO 25 KNOTS EXPECTED OVER
MUCH OF THE NEARSHORE AREAS. PERSISTENT NORTHWESTERLY WINDS OVER THE
LENGTH OF LAKE HURON WILL ALSO ALLOW WAVE HEIGHTS TO BUILD AS HIGH
AS 7 FEET OVER THE NEARSHORE WATERS. SMALL CRAFT ADVISORIES ARE IN
EFFECT FROM THIS AFTERNOON THROUGH SUNDAY AFTERNOON FOR NEARSHORE
WATERS BETWEEN PORT AUSTIN AND PORT SANILAC. WIND SPEEDS WILL
DECREASE ON SUNDAY AS HIGH PRESSURE BUILDS INTO THE AREA.

WATERSPOUTS WILL BE POSSIBLE TODAY AND TONIGHT ACROSS ALL MARINE
WATERS AS A SEASONABLY COLD AIRMASS SETTLES IN OVER THE WARM LAKE
WATERS...CREATING VERY UNSTABLE CONDITIONS.

ANOTHER ROUND OF STRONG WINDS IS EXPECTED ON MONDAY AS A STRONG LOW
PRESSURE SYSTEM TRACKS ACROSS ONTARIO. ADDITIONAL SMALL CRAFT
ADVISORIES MAY BE NECESSARY...AND A GALE WATCH MAY BE NEEDED FOR
PORTIONS OF LAKE HURON.

.AVIATION...ISSUED 135 AM EDT SAT SEP 22 2012

//DISCUSSION...

DRIER AIR PUSHING INTO THE REGION WILL KEEP CHANCES FOR SHOWERS LOW
FOR THE REMAINDER OF THE NIGHT. A STRONG UPPER LEVEL DISTURBANCE
WILL TRACK ACROSS SOUTHERN MICHIGAN AND NORTHERN OHIO THIS
AFTERNOON. THIS WILL BRING ADDITIONAL CHANCES FOR RAIN
SHOWERS...PRIMARILY FROM PTK SOUTH. LAKE EFFECT PROCESSES AND STEEP
LAPSE RATES GENERATED AS COLDER AIR ADVECTS IN AT THE UPPER LEVELS
WILL ALSO CONTRIBUTE TO SHOWER CHANCES ACROSS ALL OF SOUTHEAST
MICHIGAN TODAY...WHICH SHOULD END BY MIDNIGHT. A THUNDERSTORM WILL
ALSO BE POSSIBLE. BOTH SHOWERS AND THUNDERSTORMS WILL HAVE A GOOD
POTENTIAL TO PRODUCE SMALL HAIL THROUGH THIS EVENING.

//DTW THRESHOLD THREATS...

* LOW CONFIDENCE WITH CEILINGS DROPPING BELOW 5000 FEET THROUGH 18Z
TODAY. MEDIUM CONFIDENCE WITH CEILINGS AT OR BELOW 5000 FEET FROM
18Z-00Z...ESPECIALLY IN SHOWERS OR THUNDERSTORMS.
