AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
403 PM EST TUE FEB 28 2012

.SHORT TERM...TONIGHT THROUGH EARLY WEDNESDAY

THE UPPER WAVE POSITIONED ALONG THE EASTERN ROCKIES THIS AFTERNOON
WILL LIFT NORTHEASTWARD INTO THE UPPER MIDWEST THROUGH THE EVENING
HOURS, DEVELOPING A CLOSED CIRCULATION AS IT DOES SO. VIGOROUS
SHORTWAVE ENERGY ROTATING AROUND ITS PERIPHERY WILL PROVIDE ABUNDANT
MID LEVEL FORCING FOR THE SAME REGION, WHICH WILL ALLOW THE SURFACE
LOW TO STEADILY DEEPEN THROUGH THE OVERNIGHT PERIOD. THIS PERIOD OF
DEEPENING WILL BE SUPPLEMENTED BY LEFT EXIT REGION SUPPORT COURTESY
OF A DEVELOPING UPPER JET OVER THE CENTRAL AND SOUTHERN PLAINS.

DEEP SOUTHERLY FLOW WILL DEVELOP IN RESPONSE TO SUBSEQUENT FALLING
HEIGHTS ACROSS THE CENTRAL UNITED STATES, WITH THE LOWER
TROPOSPHERIC WARM FRONT EXPECTED TO BECOME INCREASINGLY ORGANIZED
THROUGH THE NIGHT, WITH THE ACTIVE 850MB FRONT IS FORECAST TO ARRIVE
ON THE DOORSTEP AROUND 09Z. A HEALTHY RESPONSE OF DEEP ISENTROPIC
ASCENT WILL ALLOW A SURGE OF MOISTURE CHARACTERIZED BY PWATS SURGING
TO AN UNSEASONAL 0.8" TO 0.9" TO ASCEND ALONG THE SLOPED FRONTAL
ZONE INTO THE CWA, PROVIDING PLENTIFUL MOISTURE CONTENT FOR THE
DOMINANT FGEN BAND. IN ADDITION, UPPER TROP PLOTS SUGGEST SOME
DEGREE OF COUPLING BETWEEN THE AFOREMENTIONED DEVELOPING JET OVER
THE CENTRAL/SOUTHERN PLAINS AND THE JET CURRENTLY POSITIONED ACROSS
SOUTHERN ONTARIO, WITH STRONG UPPER LEVEL DIVERGENCE FORECAST TO
OVERSPREAD SOUTHEAST MICHIGAN COINCIDENT WITH THE ARRIVAL OF THE
STRONGEST FGEN FORCING. CURRENT THINKING QPF-WISE IS THAT THE
HIGHEST PRECIP RATES WILL MOST LIKELY BE FOUND ACROSS THE SAGINAW
VALLEY, WHERE MID LEVEL FORCING AND FGEN RESPONSE WILL BE THE
STRONGEST, AND OVER THE SOUTHERN/SOUTHEASTERN CWA ALONG THE NOSE OF
THE SURGING 60KT LOW LEVEL JET. FROM A CONCEPTUAL STANDPOINT, QPF
DEPICTED IN THE 12Z ECMWF SHOWS THIS WELL.

FORECAST SOUNDINGS SUGGEST THAT ALL LOCATIONS WILL BEGIN AS SNOW,
ESPECIALLY FURTHER NORTH, WITH MORE BORDERLINE SOUNDINGS FROM M59
SOUTHWARD, WHERE SNOW WILL BE SHORTER LIVED AND ONLY MINOR
ACCUMULATIONS OF A HALF INCH OR LESS ARE EXPECTED. NORTH OF
INTERSTATE 69, A SLIGHTLY LONGER DURATION AND STRONGER FORCING
SUGGEST 2 TO 4 INCHES WILL BE POSSIBLE, ESPECIALLY ACROSS THE
SAGINAW VALLEY. THE REAL FORECAST ISSUE WILL BE THE DOMINANT PTYPE
FROM ROUGHLY FLINT TO DETROIT, WHICH WILL DEPEND ON THE
STRENGTH/TIMING OF THE WARM NOSE ALOFT, WHICH WILL ALSO CAST SOME
UNCERTAINTY ON THE FORECAST SNOW AMOUNTS ACROSS THE NORTH. A QUICKER
CHANGEOVER THERE WOULD MEAN GREATER ICING POTENTIAL AND WOULD EAT
INTO SNOW ACCUMS. FROM A SYNOPTIC AND MESOSCALE PERSPECTIVE, THE
SETUP IS A FAVORABLE ONE FOR FREEZING RAIN...GIVEN THE TIMING OF THE
FORCING AND WARM/MOIST SURGE ALOFT WHILE AT THE SAME TIME, THE HIGH
PRESSURE OVER THE AREA TODAY WILL HAVE MIGRATED EASTWARD AND WILL
PROVIDE A STOUT EASTERLY WIND COMPONENT CAPABLE OF MAINTAINING
PERSISTENT DIABATIC COOLING AND A SUB-FREEZING NEAR-SURFACE LAYER.
THUS, DESPITE SOME UNCERTAINTIES REGARDING COVERAGE/INTENSITY, THE
FEELING IS THAT THE POTENTIAL FOR MIXED PRECIP IS HIGH, WITH THE
DOMINANT PTYPE STILL FORECAST TO BE FREEZING RAIN ACROSS THE CENTRAL
PORTION OF THE CWA. COMBINED WITH POTENTIALLY HAZARDOUS TIMING
CENTERED AROUND THE MORNING RUSH, FEEL THAT AN WINTER WX ADVISORY IS
AN APPROPRIATE WAY TO GO. THE NORTHERN SECTION OF THE ADVISORY IS
UNLIKELY TO SEE SNOW THAT MEETS ADVISORY CRITERIA, BUT THE POTENTIAL
FOR SNOW TO END AS A FEW HOURS OF FREEZING DRIZZLE, OR POTENTIALLY
EVEN A SHORTER PERIOD OF FZRA, WARRANTED EXTENDING THE ADVISORY ALL
THE WAY TO THE NORTH. AS NOTED IN PREVIOUS DISCUSSIONS, WILL HEDGE
ICE ACCUMS TOWARD A LESS EFFICIENT ACCUMULATION OF ICE AROUND A
TENTH OF AN INCH.

&&

.LONG TERM...

PRONOUNCED MID LEVEL DRY SLOT (700 MB) WILL BE IN PLACE TOMORROW
AFTERNOON...BUT LOW LEVEL CONVERGENCE WITH THE OCCLUSION/WARM FRONT
MAY BE SUFFICIENT FOR PROLONGING THE DRIZZLE/LIGHT RAIN SHOWERS
(MAINLY NORTH). THE WEAKENING/FILL LOW WILL WORK THROUGH
NORTHERN LOWER MICHIGAN TOMORROW NIGHT...WITH GOOD LOW LEVEL COLD
ADVECTION PROGGED...AS 925 MB TEMPS FALL TO AROUND -2 C BY 12Z
THURSDAY. THE CYCLONIC LOW LEVEL FLOW AND 700 LOW/COLD POOL (-12 TO
-14 C) WILL SUPPORT SNOW SHOWERS...AGAIN MAINLY NORTH...CLOSER TO
THE MID LEVEL CIRCULATION.

PLANNING ON A CLOUDY/MOSTLY CLOUDY DAY ON THURSDAY WITH
THE...SUPPORTED BY GFS 925 MB RH/EUROPEAN 850 MB RH...AND PREFER THE
INHERITED MAX GRID...WHICH UNDERCUTS GUIDANCE BY A COUPLE DEGREES.

THURSDAY NIGHT WE SHOULD LOSE THE CLOUD COVER...BUT WE BEGIN TO WARM
ADVECT...WHICH SHOULD HELP STABLIZE TEMPS AROUND THE 30 DEGREE MARK.

TWO STRONG UPPER LEVEL WAVES...ONE OVER THE GULF OF ALASKA...AND THE
OTHER OFFSHORE OF VANCOUVER IS THE FOCUS FOR THE END OF THE WORK
WEEK...AS THE CONSOLIDATED TROUGH WORKS THROUGH THE ROCKIES ON
THURSDAY...WITH CYCLOGENESIS OCCURRING OVER THE CENTRAL PLAINS. ONE
MORE UPPER WAVE WEST OF ALASKA WILL BE COMING INTO PLAY...SWINGING
THROUGH THE BASE OF THE TROUGH...TAPPING PACIFIC/GULF OF MEXICO
MOISTURE. MAIN QUESTION IS WHETHER WE WILL BE DEALING WITH NORTHERN
AND SOUTHERN STREAM LOWS...OR A PHASED RAPIDLY DEEPENING SINGLE
LOW...POTENTIAL BOMB...PER GFS. PREFERENCE WILL BE WITH THE 12Z
EUROPEAN WHICH IS SKEWED TOWARD A STRONGER LOW LIFTING NORTH THROUGH
LOWER MICHIGAN/CENTRAL GREAT LAKES...BUT NOT AS DEEP AS THE LOW THE
GFS IS ADVERTISING. GOOD CHANCE OF MUCH OF THE CWA PUNCHING INTO THE
50S...WITH POTENTIAL THUNDERSTORMS WITH NEGATIVE LIS ADVERTISED.

PER 12Z EURO...
LONGWAVE TROUGH IN PLACE FOR THE WEEKEND WILL PROVIDE SEASONABLE
COOL TEMPS...AS 850 MB TEMPS FALL TO -10 TO -12 C.
A WARMING TREND COMMENCES EARLY NEXT WEEK AS RIDGE BUILDS INTO THE
AREA....SUPPORTING TEMPS UP AROUND 50 DEGRESS AGAIN BY TUESDAY

&&

.MARINE...

WAVES OVER LAKE HURON WILL CONTINUE TO DIMINISH IN HEIGHT THROUGH
THE LATE MORNING AS HIGH PRESSURE REMAINS IN CONTROL OVER THE AREA.
WAVES SHOULD DECREASE BELOW 4 FEET BY 1000 AM.

EAST TO SOUTHEAST FLOW WILL DEVELOP TONIGHT AND WEDNESDAY IN ADVANCE
OF AN APPROACHING LOW PRESSURE SYSTEM. WINDS MAY ATTAIN GALE FORCE
ACROSS THE NORTHERN HALF OF LAKE HURON AS THE LOW DRAWS CLOSER ON
WEDNESDAY...WITH GUSTS TO 40 KNOT GALES POSSIBLE. WARMER AIR SURGING
UP INTO THE AREA BY WEDNESDAY EVENING SHOULD USHER IN A MORE STABLE
MARINE ENVIRONMENT...ALLOWING GALE FORCE WIND GUSTS TO DIMINISH IN
THE EVENING.

WHILE WINDS WILL NOT BE AS STRONG ACROSS THE REMAINDER OF THE
CENTRAL GREAT LAKES...PERSISTENT EASTERLY FLOW SHOULD ALLOW WAVE
HEIGHTS TO BUILD IN EXCESS OF 4 FEET ACROSS WESTERN LAKE ERIE AND
THE NEARSHORE PORTIONS OF LAKE HURON (EXCLUDING SAGINAW BAY) BY
WEDNESDAY MORNING. WAVE HEIGHTS WILL DIMINISH QUICKLY BY WEDNESDAY
EVENING AS A COLD FRONT PUSHES ACROSS THE AREA AND FLIPS WINDS
QUICKLY TO THE WEST. SMALL CRAFT ADVISORIES WILL LIKELY BE REQUIRED
ON WEDNESDAY FOR WESTERN LAKE ERIE AND MUCH OF THE LAKE HURON
NEARSHORE WATERS.

ANOTHER LOW PRESSURE SYSTEM WILL DEEPEN AS IT LIFTS ACROSS THE GREAT
LAKES ON FRIDAY. THIS SYSTEM MAY POTENTIALLY BRING ANOTHER ROUND OF
STRONG WINDS FRIDAY NIGHT THROUGH SATURDAY.

//DISCUSSION...

VFR CONDITIONS AND LIGHT SOUTHEAST WINDS WILL PERSIST FOR THE
REMAINDER OF THE DAY BEFORE CONDITIONS BEGIN A DOWNWARD TREND TO IFR
AS DEEPER MOISTURE SUGGEST INTO THE AREA HEAD OF AN APPROACHING WARM
FRONT. PRECIPITATION WILL SPREAD INTO THE REGION AFTER MIDNIGHT,
MAINLY AFTER ABOUT 08Z. THE DOMINANT PRECIPITATION TYPE WILL BE
DIFFICULT TO DETERMINE FOR ANY ONE LOCATION, BUT THE CURRENT FORECAST CALLS
FOR A TRANSITION FROM SNOW TO FREEZING RAIN TO RAIN TO BE FASTER
ACROSS THE SOUTH, INCLUDING DTW. FOR MBS, PTYPE WILL BE MOSTLY SNOW
RESULTING IN THE POTENTIAL FOR A 2 TO 4 INCHES OF ACCUMULATION. IN
BETWEEN, MAINLY PTK AND FNT, POTENTIALLY AS FAR SOUTH AS DTW, A
PERIOD OF FREEZING RAIN MIXED WITH SLEET WILL HAVE THE BEST CHANCE
TO PERSIST FOR A FEW HOURS. THIS WILL BE ESPECIALLY TRUE AS DRY
SURFACE WINDS INCREASE OUT OF THE EAST COINCIDENT WITH THE ARRIVAL
OF THE BULK OF THE PRECIPITATION. THIS DRY AIR WILL BE A SOURCE OF
PLENTIFUL DIABATIC COOLING NEAR THE SURFACE THAT IS EXPECTED TO HOLD
TEMPERATURES BELOW FREEZING UNTIL AT LEAST DAY BREAK. HOWEVER,
PRECIPITATION TYPE AND, SPECIFICALLY, THE DURATION OF FREEZING RAIN
FOR ANY GIVEN POINT STILL REPRESENTS THE MOST UNCERTAIN ASPECT OF
THE FORECAST.

FOR DTW...PRECIPITATION IS STILL FORECAST TO REACH THE AIRFIELD
BETWEEN 07Z AND 09Z. AFTER A BRIEF PERIOD OF SNOW TO START,
PRECIPITATION TYPE WILL TRANSITION TO FREEZING RAIN WHICH MAY MIX
WITH SLEET AT TIMES. THERE IS SOME UNCERTAINTY REGARDING HOW LONG
THE WINDOW FOR FREEZING RAIN FOR LAST, BUT THE PRIME TIME IS
EXPECTED TO BE BETWEEN ABOUT 10Z AND 14Z. DIURNAL HEATING WILL HELP
BORDERLINE SURFACE TEMPERATURES RISE ABOVE FREEZING BY MID MORNING,
WHICH WILL ALLOW PTYPE TO MAKE A CHANGE OVER TO RAIN AND THEN
DRIZZLE.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN CEILINGS BELOW 5000 FT.

* MEDIUM CONFIDENCE IN A PRECIPITATION TYPE OF SNOW TRANSITIONING TO
MOSTLY FREEZING RAIN.
