AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
338 PM EDT TUE SEP 25 2012

.SHORT TERM...THIS AFTERNOON AND TONIGHT

A SLOWLY MOVING COLD FRONT...ANALYZED FROM CENTRAL LAKE HURON TO
SOUTHERN WISCONSIN AT 18Z...WILL SLOWLY SINK SOUTH TOWARDS THE
MICHIGAN/OHIO BORDER LATE TONIGHT. FOCUS CONTINUES TO BE ON THE
PRECIPITATION TO OUR SOUTH WHICH HAS DISSIPATED QUITE RAPIDLY AS IT
HEADS TOWARDS THE VERY DRY AIR IN PLACE ACROSS THE SOUTHERN GREAT
LAKES. THE PUSH SOUTHWARD OF THE AFOREMENTED COLD FRONT WILL BE
HELPED ALONG BY THE LARGE HIGH PRESSURE SYSTEM BUILDING INTO THE
NORTHERN PLAINS AND UPPER MISSISSIPPI VALLEY WHILE A WEAK LOW
PRESSURE SYSTEM DEVELOPS ALONG THE FRONT AND MOVES THROUGH THE
SOUTHERN GREAT LAKES TONIGHT.

WHILE THE COLD FRONT WILL BE TOO DRY TO PRODUCE MUCH IN THE
WAY OF RAIN...THE FORCING ASSOCIATED WITH A WEAK LOW PRESSURE SYSTEM
MOVING THROUGH THE SOUTHERN GREAT LAKES WILL BRING THE CHANCE FOR
RAIN ACROSS THE EXTREME SOUTHERN CWA DURING THE OVERNIGHT HOURS.
DESPITE THE LOW...THERE IS A LOT OF DRY AIR IN PLACE ACROSS THE
CENTRAL GREAT LAKES WITH MOISTURE LIMITED TO THE LOW LEVELS WITH NOT
MUCH MID LEVEL FRONTOGENESIS FORECAST WITH THIS SUITE OF MODELS.
GIVEN THERE IS A RIBBON OF HIGHER THETA-E AIR WILL CONTINUE SLIM
CHANCES ACROSS THE FAR SOUTHERN CWA...BUT REMOVE THUNDER GIVEN THE
LIMITED MOISTURE DEPTH AND LACK OF DEEP FORCING AND INSTABILITY.

SHALLOW COLD AIR ADVECTION IN THE WAKE OF THE FROPA TONIGHT WILL
ALLOW TEMPS TO DROP OFF INTO THE 40S NORTH OF THE I-69 CORRIDOR AND
50S SOUTH.

&&

.LONG TERM...

NORTHWEST FLOW AROUND THE BACK SIDE OF THE HUDSON BAY UPPER LOW WILL
CARRY A COUPLE OF SHORTWAVES THROUGH THE GREAT LAKES BETWEEN NOW AND
WEDNESDAY. THE 12Z NAM, WHICH LOOKS TO HAVE A GOOD HANDLE ON THESE
FEATURES OF INTEREST, BRINGS A TRAILING SHORTWAVE CURRENTLY OVER
WESTERN ONTARIO INTO THE WESTERN GREAT LAKES BY WEDNESDAY MORNING.
THE RESULTANT AMPLIFICATION OF THE LONGER WAVE TROUGH IS FORECAST TO
BE FORCING A COLD FRONT OUT OF THE AREA AT THE BEGINNING OF THE LONG
TERM PERIOD. A FEW SHOWERS WILL THEREFORE BE POSSIBLE ALONG THE
MICHIGAN/OHIO BORDER AHEAD OF THE UPPER TROUGH AXIS AND PARTICULARLY
ALONG THE SURFACE COLD FRONT, MAINLY IN THE MORNING BEFORE DEEPER
MOISTURE ALONG THE FRONT IS SHUNTED FULLY TO THE SOUTH. HIGH
TEMPERATURES WILL BE NOTICEABLY COOLER ACROSS NORTHERN AREAS AS THEY
FALL INTO THE LOW TO MID 60S, BUT WILL AGAIN REACH AROUND 70 DEGREES
IN THE DETROIT METRO AREA WHERE THE BULK OF THE COOLER AIR WILL NOT
ARRIVE UNTIL THE EVENING.

SPRAWLING SURFACE HIGH PRESSURE WILL THEN BUILD IN UNDER REBOUNDING
HEIGHTS ALOFT WEDNESDAY NIGHT THROUGH FRIDAY. DESPITE PLENTY OF
INSOLATION, STRONG SUBSIDENCE WILL CAP MIXING HEIGHTS AND LIMIT
AFTERNOON HIGHS TO THE 60S ON BOTH DAYS AS THE THERMAL TROUGH
SETTLES OVERHEAD. MOSTLY CLEAR SKY CONDITIONS AND A WEAK PRESSURE
GRADIENT ALONG WITH A FRESH CANADIAN AIRMASS WILL ENSURE CHILLY
NIGHTS ON WEDNESDAY AND THURSDAY. LOWS WILL RANGE FROM THE MID/UPPER
30S ACROSS THE NORTHWEST TO THE 40S IN DETROIT METRO, MAKING SOME
FROST POSSIBLE FOR SOME LOCATIONS ON BOTH NIGHTS.

&&

.MARINE...

A COLD FRONT OVER CENTRAL LAKE HURON WILL BE DRIVEN SOUTH
TONIGHT...REACHING LAKE ERIE BY LATE WEDNESDAY MORNING. THE PASSAGE
OF THE COLD FRONT WILL VEER THE WINDS TO THE NORTH-NORTHEAST.
SHALLOW COLD AIR ADVECTION TONIGHT WILL BOOST INSTABILITY OVER LAKE
HURON. THIS WILL RESULT IN A BRIEF INCREASE IN THE WINDS LATE
TONIGHT ALONG THIS PUSH OF COLDER AIR. AS A RESULT...WAVES OVER
SOUTHERN LAKE HURON WILL BRIEFLY INCREASE WED MORNING. ALTHOUGH
WINDS WILL REMAIN BELOW SMALL CRAFT CRITERIA...WAVES WILL BUILD UP
WITH THE LONG FETCH ACROSS THE TIP OF THE THUMB LATE TONIGHT.
THEREFORE WILL ISSUE A SMALL CRAFT ADVISORY FOR THESE AREAS WITH
THIS ISSUANCE. WAVES ARE FORECAST TO CONTINUE INTO WEDNESDAY WITH
THE LONG FETCH BRINGING HIGHER WAVES TO THE REST OF THE LAKE HURON
NEARSHORE AREAS WEDNESDAY MORNING. GIVEN THE LATER ONSET WILL ISSUE
SMALL CRAFTS FOR THE TWO SOUTHERN LAKE HURON NEARSHORE ZONES
WEDNESDAY MORNING. WINDS WILL THEN WEAKEN CONSIDERABLY LATE
WEDNESDAY AS STRONG HIGH PRESSURE EXPANDS ACROSS THE GREAT LAKES.
HOWEVER HIGHER WAVES WILL CONTINUE THROUGH MUCH OF WEDNESDAY NIGHT.
THE SMALL CRAFT ADVISORIES WILL CONTINUE INTO MUCH OF WEDNESDAY
NIGHT GIVEN THE RESIDUAL WAVE ACTION ACROSS LAKE HURON. THE HIGH
PRESSURE SYSTEM WILL DOMINATE THE FORECAST INTO THE WEEKEND.

.AVIATION...ISSUED 117 PM EDT TUE SEP 25 2012

//DISCUSSION...

DESPITE A COLD FRONT OVER NORTHERN LOWER MICHIGAN THAT CONTINUES TO
SLOWLY MOVE SOUTH...THERE IS A MUCH LOOSER PRESSUE GRADIENT IN
PLACE ACROSS SOUTHERN MICHIGAN AS S-SW WINDS GUST IN THE 12 TO 16
KNOT RANGE THIS AFTERNOON. THIS COLD FRONT WILL MOVE SOUTH TONIGHT
AND WED MORNING...MOVING ACROSS MBS AROUND 03Z AND DTW AROUND 14Z
WED. THE PASSAGE OF THE FRONT WILL BE MARKED BY A VEERING OF THE
WINDS TO THE N-NW.

FOR DTW...DESPITE EARLIER RUNS INDICATING PRECIPITATION MAKING IT TO
THE METRO AIRPORT...RECENT RUNS ARE LESS BULLISH WITH THE RAIN
LIMITED TO AREAS SOUTH OF THE OHIO BORDER. CLOUDS SHOULD STILL LOWER
BUT PRECIPITATION IS LOOKING LESS LIKELY WITH THIS SUITE OF MODEL
RUNS.

//DTW THRESHOLD THREATS...

* MEDIUM CONFIDENCE CEILINGS WILL FALL BELOW 5000 FT AFTER 03Z.
