AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1239 PM EST SUN DEC 14 2008

.AVIATION...

A MOIST SOUTHWEST FLOW ENVIRONMENT IS FIRMLY ENTRENCHED ACROSS
SOUTHEAST MICHIGAN AS A STRONG LOW PRESSURE SYSTEM LIFTS NORTHWARD
ACROSS THE UPPER MIDWEST. NUMEROUS LIGHT RAIN SHOWERS HAVE
BLOSSOMED LATE THIS MORNING...MAINLY CLIPPING THE SOUTHERN TWO
THIRDS OF THE FORECAST AREA. AFTER THIS CURRENT ACTIVITY...THE
TAF SITES SHOULD WITNESS A RELATIVELY QUIET PERIOD LATE THIS
AFTERNOON/EARLY EVENING BEFORE A MORE WIDESPREAD COVERAGE AFFECTS
ALL OF SOUTHERN LOWER MICHIGAN OVERNIGHT. CEILINGS AND
VISIBILITIES ARE EXPECTED TO LOWER INTO A LOW END MVFR/IFR THIS
EVENING AS FULLY SATURATED CONDITIONS ALLOW FOR BR. WITH THIS
ISSUANCE HAVE TIMED THE PASSAGE OF A COLD FRONT FROM NORTH TO
SOUTH TOMORROW MORNING. EXPECT SUSTAINED SOUTHERLY WINDS TO
STEADILY INCREASE OVERNIGHT WITH THE APPROACHING FRONTAL
SYSTEM...WITH A QUICK VEERING TO THE WEST AFTER PASSAGE...GUSTS
TOMORROW MORNING INCREASING TO THE LOWER 30 KNTS.

&&

.PREV DISCUSSION...ISSUED 349 AM EST SUN DEC 14 2008

SHORT TERM...TODAY

THE MIX OF SNOW...SLEET...FREEZING RAIN AND RAIN WILL CHANGEOVER TO
ALL RAIN EARLY THIS MORNING AS 850 MB TEMPS WARM TO +3 TO +5 CELSIUS
WITH SURFACE TEMPERATURES WARMING INTO THE UPPER 30S. SHORTLY AFTER
THE CHANGEOVER...DRY AIR BETWEEN 400 AND 700 MB COUPLED WITH THE
LOSS OF FRONTOGENESIS CURRENTLY PRESENT BETWEEN 700 AND 850 MB WILL
LEAD TO A BREAK IN THE PRECIPITATION DURING THE AFTERNOON HOURS.
WITH THE DRY AIR AND LOSS OF FORCING...WILL KEEP THE PRECIP
CHANCES OUT OF THE LIKELY CATEGORY. HOWEVER ABUNDANT LOW LEVEL
MOISTURE MAY BE ABLE TO SQUEEZE OUT SOME LIGHT RAIN OR DRIZZLE
DESPITE THE LACK OF SUPPORT IN THE MIDDLE LEVELS SO WILL LEAVE
POPS IN THE CHANCY CATEGORY.

LONG TERM...TONIGHT THROUGH SATURDAY

LONGWAVE PATTERN WILL REMAIN VERY ACTIVE THROUGH NEXT WEEKEND...AS
UPPER RIDGING PARKED ACROSS THE SOUTHEAST CONUS AND MEAN TROUGHING
OUT WEST MAINTAIN A BROAD MID/UPPER LEVEL SOUTHWEST FLOW ACROSS
THE GREAT LAKES. PERSISTENT 120+ KNOT UPPER LEVEL JET WRAPPING
AROUND THE BASE OF THE TROUGH WILL COMBINE WITH SEVERAL STRONGER
SHORTWAVES EJECTING NORTHEAST TO BRING SEVERAL ROUNDS OF
PRECIPITATION AND KEEP TEMPERATURES ON A ROLLER COASTER RIDE.

FIRST VERY DYNAMIC SYSTEM CONTINUING TO ORGANIZE AS IT LIFTS INTO
THE CENTRAL PLAINS THIS MORNING.  SFC LOW WILL QUICKLY TRANSLATE
NORTHEAST AND ACROSS LAKE SUPERIOR BY TONIGHT IN RESPONSE TO RAPID
UPSTREAM HEIGHT FALLS/STRONG LARGE SCALE ACCENT...SENDING A COLD
FRONT RAPIDLY EASTWARD INTO SOUTHERN MICHIGAN OVERNIGHT.
PRE-FRONTAL MOISTURE TRANSPORT/THETA-E ADVECTION WILL STRENGTHEN
WITHIN THE DEEP SOUTHWEST FLOW THROUGH THE EVENING...ALLOWING RAIN
TO EXPAND IN COVERAGE WITH TIME.  BEST LARGE SCALE ACCENT WILL
ARRIVE AFTER 06Z AS SOUTHEAST MICHIGAN FALLS WITHIN FAVORABLE EXIT
REGION JET DYNAMICS AND INCREASING LOW LEVEL FRONTAL CONVERGENCE...
SUPPORTING CATEGORICAL POPS FOR THE OVERNIGHT HOURS. MAY EVEN SEE AN
EMBEDDED LIGHTNING STRIKE OR TWO ACROSS THE FAR SOUTH AS A NARROW
SLIVER OF ELEVATED INSTABILITY WORKS IN.  IMPRESSIVE WIND FIELD
SUSTAINED BY A 50-70 KNOT LOW LEVEL JET WITH MAINTAIN GUSTS OF 25-30
KNOTS OVERNIGHT.

COLD FRONT WILL SWEEP EAST ACROSS THE AREA AROUND 12Z MONDAY
MORNING.  LOW LEVEL WIND FIELD WILL PICK UP IN INTENSITY FOR A
PERIOD JUST AHEAD OF THE FRONT...PERHAPS AIDED BY ANY HEAVIER
SHOWERS MIXING DOWN THE STRONGER WINDS JUST OFF THE SURFACE.
POST-FRONTAL WESTERLY WINDS WILL REMAIN QUITE GUSTY ON MONDAY...WITH
SOUNDINGS SHOWING WINDS OF 40-45 KNOTS JUST BELOW A STRENGTHENING
INVERSION AROUND 900 MB. THIS COMBINED WITH A DECENT ISALLOBARIC
RESPONSE WILL LEAD TO A PERIOD WHERE GUSTS COME CLOSE TO ADVISORY
CRITERIA (45 MPH). HIGHS WILL OCCUR RIGHT AT 12Z MONDAY...BEFORE
PRONOUNCED COLD AIR ADVECTION SENDS TEMPERATURES ON A DOWNWARD
SPIRAL THROUGH THE DAY.  DEEP MOISTURE STRIPS AWAY QUICKLY THROUGH
THE MORNING...JUST AS THERMAL PROFILES BECOME FAVORABLE FOR A
CHANGEOVER...LEAVING JUST A FEW RA/SN SHOWERS AND LITTLE IF ANY
ACCUMULATION THROUGH THE DAY.

AFTER A BRIEF PERIOD OF HIGH PRESSURE ALLOWS TEMPERATURES TO
PLUMMET MONDAY NIGHT (A FEW SINGLE DIGIT LOWS ASSUMING CLOUDS
CLEAR)...THE NEXT SHOT OF PRECIPITATION QUICKLY ARRIVES ON THE
DOORSTEP BY TUESDAY AFTERNOON/EVENING.  THERMAL PROFILES SOLIDLY
SUPPORT ALL SNOW WITH THIS PRECIP SHIELD.  STRONG LARGE SCALE
FORCING/FAVORABLE UPPER JET SUPPORT WITH MIXING RATIOS AROUND 3 G/KG
SUGGEST THERE IS POTENTIAL OF REALIZING A MODEL CONSENSUS QPF NEAR
2...LEADING TO SEVERAL INCHES OF ACCUMULATION TUESDAY NIGHT.
ANOTHER SYSTEM WILL APPROACH THE GREAT LAKES TOWARD THE END OF THE
WEEK...BUT A DEEPENING WARM LAYER WILL LIKELY CREATE MORE OF A MIXED
PRECIP SCENARIO.

MARINE...

A STRONG LOW PRESSURE SYSTEM WILL MOVE INTO THE WESTERN GREAT LAKES
TODAY...THEN DRAG A COLD FRONT THROUGH THE CENTRAL GREAT LAKES
TONIGHT AS THE LOW MOVES INTO SOUTHERN CANADA. HIGH PRESSURE WILL
THEN SLOWLY BUILD INTO THE WESTERN GREAT LAKES MONDAY NIGHT BEHIND
THE LOW. THIS LOW WILL BRING SOUTHERLY GALES TO LAKE HURON TODAY AND
TONIGHT...AS WESTERLY GALES PERSIST BEHIND THE FRONT INTO MONDAY.
GALE FORCE WINDS SHOULD SETTLE DOWN MONDAY NIGHT AS THE HIGH BUILDS
INTO THE REGION.
