.AVIATION...

//DISCUSSION...

LOW PRESSURE OVER NE MISSOURI IS FORECAST TO TRACK ACROSS SE MI
BETWEEN 15Z AND 18Z ON TUESDAY. STRONG LOW LEVEL MOISTURE TRANSPORT
IN ADVANCE OF THIS SYSTEM WILL ALLOW A RAPID DROP IN CEILINGS AND
VISIBILITIES TONIGHT. THE 18Z MODEL SOUNDINGS AND MOS GUIDANCE
CONTINUE TO BE TOO MOIST IN THE LOW LEVELS AND THUS CONTINUE TO
ADVERTISE MUCH LOWER CEILING HEIGHTS IN COMPARISON TO OBSERVATIONS.
NONETHELESS...OBSERVATIONS OVER THE LAST HOUR HAVE INDICATED
CEILINGS RAPIDLY DROPPING BELOW 3K FT WITH LIGHT RAIN/DRIZZLE
DEVELOPING ACROSS SRN MI. BASED ON OBSERVATIONAL DATA AND GIVEN
CONTINUED LOW LEVEL MOISTENING...CEILINGS ARE EXPECTED TO DROP AT OR
BELOW 1000 FT BETWEEN 03Z AND 06Z...WHERE THEY WILL REMAIN THROUGH
DAYBREAK. GIVEN THE WARM LOW LEVEL AIRMASS...PRECIP TONIGHT WILL
REMAIN ENTIRELY IN THE FORM OF RAIN.

FOR DTW...EXPECTING THE LOWEST CIGS AND VSBY WILL LIKELY OCCUR
AROUND DAYBREAK THROUGH ROUGHLY 15Z AS AN ASSOCIATED WARM FRONT
LIFTS INTO THE METRO AREA. STRONG COLD AIR ADVECTION LATE TUES
AFTERNOON AND EVENING WILL TRANSITION RAIN OVER TO SNOW SHOWERS AND
WILL LEAD TO A PERIOD A VERY GUSTS W-NW WINDS.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE CEILINGS WILL REMAIN BELOW 5000 FT THROUGH THE TAF
PERIOD.

* LOW CONFIDENCE ON WHETHER CIGS OR VSBY WILL DROP BELOW 200FT OR
1/2SM TUES MORNING.

* HIGH CONFIDENCE PRECIP TYPE WILL REMAIN RAIN TONIGHT THROUGH EARLY
TUES AFTERNOON.

* HIGH CONFIDENCE WIND GUSTS WILL EXCEED 25 KNOTS AT 280-310 DEGREES
AFTER 20Z TUES.

.PREV DISCUSSION...ISSUED 326 PM EST MON JAN 16 2012

SHORT TERM...TONIGHT

MODELS OVER DID THE 925 MB MOISTURE TODAY...AND SUNSHINE WAS AROUND
FOR A GOOD PART OF THE DAY...ALLOWING TEMPS TO CLIMB INTO THE LOW TO
MID 40S FOR MUCH OF THE AREA. THIS IS GOOD NEWS...AS PRECIPITATION
TYPE IS TRENDING TO ALL RAIN FOR TONIGHT. 12Z SOUNDINGS AT DVN/ILX
SHOWED 925 MB TEMPS OF 7 AND 8 C RESPECTIVELY...SO CONFIDENCE IN THE
FORECASTED 12Z GFS 925 TEMPS IS FAIRLY HIGH...WHICH BRINGS +2 C ALL
THE WAY TO SAGINAW BAY...WITH +7 C INFILTRATING THE CITY OF DETROIT
AND POINTS SOUTH. EVEN THE NAM FORECASTED SURFACE DEW PTS OF 32+ F
REACH THE SAGINAW BAY...INCREASING CONFIDENCE PRECIPITATION WILL BE
MOSTLY LIQUID VARIETY. BAY/MIDLAND/HURON COUNTIES ARE THE BORDERLINE
COUNTIES WHERE SOME WET BULBING COULD SUPPORT SOME FREEZING
RAIN/SNOW...BUT NOT EVEN SURE IF PRECIPITATION RATES WILL BE
SUFFICIENT...AS MODEL QPF TONIGHT IS ONLY AROUND A TENTH OF AN
INCH...AS THE DEEPER MOISTURE AND LIKELY MORE ACTIVE REGION REMAINS
JUST SOUTH OF THE MICHIGAN BORDER AS SHORTWAVE EJECTS NORTHEAST FROM
NEBRASKA. WITH DEWPOINTS CLIMBING INTO THE MID 30S...DO NOT THINK
DENSE FOG WILL BE MUCH OF AN ISSUE...WOULD PREFER TO SEE DEW PTS
CLOSER TO 40 DEGREES COME OVER THE SNOW COVER/COLD GROUND.

LONG TERM...TUESDAY THROUGH SUNDAY

UPPER LEVEL PATTERN THROUGH THE REMAINDER OF THE WORK WEEK WILL
FEATURE PROGRESSIVE LOWER AMPLITUDE FLOW...TUCKED BENEATH A
PREDOMINANT POLAR VORTEX ANCHORED OVER HUDSON BAY.  A COUPLE OF
STRONGER SHORTWAVE EMBEDDED WITHIN THIS FLOW WILL TRANSLATE THROUGH
THE GREAT LAKES DURING THIS TIME...LEADING THE FOCUS FOR A COUPLE
PRECIPITATION OPPORTUNITIES AND DRIVING REINFORCING SHOTS OF ARCTIC
INTO THE REGION.  PATTERN ADJUSTMENT WILL ATTEMPT TO PROVIDE THE
NEXT REAL WARMUP STARTING NEXT WEEKEND.

FIRST MID LEVEL WAVE CURRENTLY NOTED ON WATER VAPOR MIGRATING ACROSS
THE INTERMOUNTAIN WEST WILL CONTINUE EASTWARD OVER THE NEXT 24
HOURS...REACHING THE GREAT LAKES BY TUESDAY EVENING.  EXPANDING
HEIGHT FALL REGION WILL POSITION THE DEEPENING ASSOCIATED SFC LOW
OVER ROUGHLY SOUTHWEST LOWER MICHIGAN AT 12Z TUE MORNING.
WIDESPREAD AREA OF LIGHT PRECIPITATION WILL LIKELY BE ONGOING
AREAWIDE AT THIS TIME DRIVEN BY SUSTAINED WAA/ISENTROPIC ASCENT AND
FAVORABLE LEFT EXIT REGION JET DYNAMICS.  12Z MODEL SUITE
MAINTAINING THE NORTHWARD TREND IN THE SFC LOW TRACK DISPLAYED BY
IT/S PREDECESSOR...ALLOWING THE WAVE TO BISECT THE FORECAST ON A
NORTHEASTWARD TRAJECTORY DURING THE DAY.  UNDER A DEEPENING
SOUTHWEST FLOW...THIS WILL EFFECTIVELY DRIVE A GOOD LOW LEVEL WARM
NOSE INTO SOUTHEAST MICHIGAN EARLY IN THE DAY.  THIS WILL SUPPORT A
NUDGE UPWARD IN DAYTIME HIGHS...RANGING FROM MID 30S NORTH TO MID
40S SOUTH.

DEEPER MID LEVEL DEFORMATION/FORCING WILL DISPLACE TO THE NORTHWEST
EARLY IN THE DAY...AS THE MOISTURE DEPTH DIMINISHES LOCALLY UNDER
WEAK MID LEVEL DRYING.  GIVEN SUFFICIENTLY ELEVATED FREEZING LEVELS
AND QUESTIONABLE MOISTURE DEPTH TO SUPPORT ICE NUCLEATION...EXPECT
AREAS OUTSIDE OF THE NORTHERN SAGINAW VALLEY TO CARRY A PREDOMINANT
LIQUID PHASE (LIGHT RAIN AND/OR DRIZZLE) WELL INTO THE AFTERNOON
PERIOD.   COLDER AIR FUNNELING IN ON DEVELOPING/GUSTY NORTHWEST
WINDS ON THE BACKSIDE WILL EVENTUALLY COOL THE COLUMN ENOUGH TO
SUPPORT SNOW...TRANSITIONING FROM NORTHWEST TO SOUTHEAST 19Z-01Z.
MID LEVEL DEFORMATION/WEAK FGEN BAND WILL PIVOT EASTWARD...CLIPPING
THE TRI-CITIES AND NORTHERN THUMB DURING THIS TIME.  THIS WILL OPEN
THE DOOR FOR A BURST OF SNOWFALL BEFORE THE MOISTURE PULLS EAST.
OVERALL LOOKING AT A SWATH OF ACCUMULATION FROM 1 TO 2 INCHES ACROSS
THIS CORRIDOR THROUGH TUESDAY EVENING...LOCALLY UP TO 3 ACROSS
NORTHERN MIDLAND/BAY. ACCUMULATION POTENTIAL TAPERS OFF QUICKLY
TOWARD THE SOUTH UNDER DIMINISHING FORCED ASCENT...WITH LITTLE
MORE THAN A FEW SNOW SHOWERS UNDER THE CAA/CYCLONIC FLOW FOR THE
DETROIT SUBURBS AND POINTS SOUTHWARD DURING THE EVENING.

ARCTIC AIR CARRYING 850 MB TEMPERATURES OF -14 TO -16C WILL BE
FIRMLY ENTRENCHED OVER SOUTHEAST MICHIGAN BY WEDNESDAY...AS WEAK
SURFACE RIDGING DRIFTS ACROSS THE AREA.  THIS AIRMASS WILL YIELD
HIGHS OF LOWER AND MIDDLE 20S.  NEXT PROGRESSIVE MID LEVEL WAVE
WILL BE ON THE DOORSTEP BY WEDNESDAY NIGHT.  WHILE THE BETTER
FORCING/CVA WILL HOLD TO THE NORTH...MODELS DO HINT AT A PERIOD OF
BETTER SYSTEM RELATIVE ISENTROPIC ASCENT EMERGING IMMEDIATELY IN
ADVANCE OF THE ASSOCIATED COLD FRONT THURSDAY MORNING.  VARYING
MODEL OPINION STILL EXISTS ON THE RESPONSE WITHIN THE MOISTURE
FIELDS...BUT ENOUGH SUPPORT REMAINS TO HIGHLIGHT A CHANCE OF SNOW
WITH SOME MINOR ACCUMS AREAWIDE DURING THIS TIME.

STRONGER SURGE OF ARCTIC AIR WILL ARRIVE IN THE WAKE OF THIS FRONTAL
PASSAGE FOR THURSDAY AND FRIDAY.  ONE FINAL WEAK SHORTWAVE/CLIPPER
RIDING THE PERIPHERY OF THE MODERATING ARCTIC FRONTAL ZONE WILL
STREAM ACROSS THE GREAT LAKES DURING THE FRIDAY PERIOD...PROVIDING
ANOTHER QUICK SHOT FOR SOME LOWER END ACCUMULATING SNOW.  HEIGHTS
WILL BEGIN TO BUILD INTO THE WEEKEND AS THE CENTRAL CANADIAN POLAR
VORTEX RETREATS TO THE NORTH.  THIS WILL ALLOW FOR SOME DEGREE OF
MODERATION IN TEMPERATURES TOWARD NORMAL/ABOVE NORMAL DURING THIS
TIME.

MARINE...

LOW PRESSURE LOOKS TO BE TRACKING THROUGH SOUTHEAST MICHIGAN
TOMORROW MORNING...DEEPENING AS IT SLIDES EAST DURING THE DAY.
STRONG LOW LEVEL COLD ADVECTION AND TIGHTENING PRESSURE GRADIENT
WILL LEAD TO STRONG NORTHWEST WINDS LATE IN THE DAY INTO TUESDAY
NIGHT...WITH GALES POSSIBLE OVER THE OPEN WATERS OF LAKE HURON. A
GALE WATCH HAS BEEN ISSUED. SMALL CRAFT ADVISORIES WILL LIKELY BE
NEEDED FOR THE NEARSHORE WATERS FOR FREQUENT GUSTS OF 25 KNOTS. HIGH
PRESSURE BUILDING IN FOR THE MID WEEK PERIOD WILL LEAD TO LIGHTER
WINDS BEFORE THE NEXT LOW PRESSURE SYSTEM AND ASSOCIATED COLD FRONT
COMES THROUGH ON THURSDAY.
