AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
356 AM EST SAT FEB 11 2012

.SHORT TERM...TODAY

COLD FRONT HAS PASSED THROUGH SE MI BRINGING IN STRONG NW WINDS
GUSTING TO 25 KNOTS AND VERY COLD AND DRY AIR WITH SFC DEWPOINTS IN
THE SINGLE DIGITS. THE WEAKENING DEFORMATION BAND WILL CONTINUE TO
PRODUCE LIGHT SNOW SHOWERS OVER MOST OF THE AREA UNTIL AROUND 12Z.
CURRENT OBS SUGGEST ANY ACCUMULATIONS WILL BE A HALF INCH OR LESS.
THE EXCEPTION WILL BE AREAS AROUND THE THUMB WHERE NORTHERLY WINDS
WILL CONTINUE TO PRODUCE LAKE EFFECT UNTIL MORNING WHEN THE WINDS
TURN A MORE NORTHWESTERLY PUSHING THE MAJORITY OF THE SNOW OFFSHORE.
EXETER RADAR IN CANADA SHOWS A RATHER BROAD AREA OF LAKE EFFECT FROM
PORT AUSTIN DOWN TO PORT HURON...WITH THE HEAVIEST BAND NEAR PORT
HURON. LOOK FOR THESE AREAS TO SEE AROUND ANOTHER INCH OVERNIGHT.

MODELS SHOW A COUPLE SHORTWAVES DIVING SOUTH OUT OF CANADA DURING
THE DAY TODAY AS FRIDAYS SURFACE LOW MOVES TOWARD THE EAST COAST AND
DEEPENS. STRONG HIGH PRESSURE BUILDING OVER THE NORTHERN PLAINS WILL
HELP KEEP THE BULK OF THE ENERGY FROM THESE WAVES TO OUR NE BUT IT
DOES LOOK LIKE THEY WILL PASS OVER LAKE HURON. THOUGH DRY AIR WILL
BE IN PLACE IN THE MID LEVELS...WEAK SURFACE HEATING EARLY IN THE
DAY WITH THE UPPER LEVEL WAVES PASSING BY WILL LIKELY LEAD TO SOME
CLOUD DEVELOPMENT AND POSSIBLY PRODUCE FLURRIES FOR A FEW HOURS IN
THE AFTERNOON. CAA ADVECTION WITH A FRESH SNOW PACK WILL KEEP TEMPS
DOWN TODAY WITH MOST MOS GUIDANCE STRUGGLING TO EXCEED 20 DEGREES
FOR MOST AREAS. GUSTS SHOULD REMAIN AROUND 20-25 KNOTS THROUGH THE
DAY AS THE GRADIENT STAYS TIGHT WITH THE HIGH OVER THE PLAINS
BUILDING INTO THE STRENGTHENING LOW OVER THE EAST COAST. OVERALL THE
MAIN CONCERN FOR TODAY WILL BE THE COLD TEMPS AND WIND PRODUCING WIND
CHILLS IN THE SINGLE DIGITS.

&&

.LONG TERM...TONIGHT THROUGH FRIDAY

LONGWAVE TROUGH AXIS ANCHORED OVER THE GREAT LAKES EARLY THIS
MORNING WILL RAPIDLY PULL EAST THROUGH THE LATTER HALF OF THE
WEEKEND.  THIS PROCESS WILL ALLOW THE LOW LEVEL WIND FIELD TO VEER
TO WEST-NORTHWEST TONIGHT.  THIS WILL PROVIDE A FAVORABLE TRAJECTORY
FOR SOME DEGREE OF LAKE MICHIGAN MOISTURE FLUX TO WORK INTO THE
REMNANT LOW LEVEL THERMAL TROUGH/SUB-INVERSION MOIST LAYER.  THIS
CONTINUES TO POINT TOWARD MAINTAINING A MORE PESSIMISTIC SKY
CONDITION THROUGHOUT THE NIGHT.  THIS COMBINED WITH A WELL MIXED
10-15 KNOT SFC-850 MB GRADIENT WILL KEEP LOWS FROM REALIZING THE
FULL POTENTIAL OF THIS ARCTIC AIR WITHIN A FRESH SNOWPACK.  LOWS IN
THE LOWER TO MIDDLE TEENS REMAIN APPROPRIATE.

CLOUD FORECAST WILL REMAIN A CHALLENGE INTO SUNDAY...AS DEEP MID
LEVEL DRYING AND INCREASING SUBSIDENCE LOWER INVERSION HEIGHTS AND
LEAVE THE MOIST LAYER 50 MILLIBARS DEEP /950-900MB/.   LATEST MODEL
SOUNDINGS INDICATE THIS WILL BE SUFFICIENT TO ENCASE THE AREA IN A
STRATOCU DECK FOR MUCH OF THE DAY...FINALLY MIXING OUT TOWARD LATE
AFTERNOON/EVENING.  THERMAL PROFILE WILL MODERATE IN RESPONSE TO THE
EXITING LOWER HEIGHT FIELD...BUT ASSUMING LIMITED INSOLATION THIS
WILL LEAVE HIGHS PREDOMINATELY IN THE UPPER 20S.  THE RADIATIONAL
COOLING POTENTIAL WILL BE MORE FAVORABLE SUNDAY NIGHT...WITH THE
COLDEST LOCALES AGAIN MAKING A RUN DOWN INTO THE LOWER TO MIDDLE
TEENS.

A SPLIT MID LEVEL FLOW WILL DEVELOP ACROSS THE CONUS FOR THE
UPCOMING WORK WEEK IN THE WAKE OF THE EXITING LONGWAVE TROUGH.  A
LEAD SOUTHERN STREAM WAVE LIFTING OUT OF THE SOUTHERN ROCKIES WILL
MERGE WITH REMNANT ENERGY DRIFTING THROUGH THE CENTRAL/NORTHERN
ROCKIES.  THE ASSOCIATED SFC CYCLOGENESIS THAT EMERGES AS THIS
TROUGH SHIFTS INTO THE SOUTHERN PLAINS WILL PROVIDE A MODEST
THERMAL/MOISTURE RESPONSE DOWNSTREAM UNDER INCREASING SOUTHWEST
FLOW.  WHILE THE STRONGER FORCING WILL REMAIN TIED TO THE SHORTWAVE
WELL TO THE SOUTH...THIS SETUP WILL BRING A NORTHEASTWARD EXPANDING
PLUME OF LOW LEVEL MOISTURE LINKED TO WEAK ISENTROPIC ASCENT DURING
THE MONDAY NIGHT AND TUESDAY PERIODS.  A BRIEF UPTICK IN CVA
ASSOCIATED WITH THE PASSAGE OF A WEAKER NORTHERN WAVE MAY ENHANCE
THE OVERALL ASCENT.  IN GENERAL...LOOKING AT SOME MINOR ACCUMS
THROUGH THIS TIME WITH EXPECTATIONS FOR A FEW HUNDREDTHS OF QPF.

UPPER HEIGHTS WILL CONTINUE TO BUILD IN ADVANCE OF THE NEXT STRONGER
SYSTEM EJECTING OUT OF THE SOUTHERN ROCKIES MID WEEK.  THE
CORRESPONDING MODERATING THERMAL FIELD WILL LEAVE THE PTYPE IN
QUESTION AS THE ASSOCIATED MOISTURE PLUME ADVECTS THROUGH SOUTHEAST
MICHIGAN IN THE THURSDAY/THURSDAY NIGHT PERIOD.  BETTER UPPER JET
SUPPORT/DYNAMICS WILL BRING A HIGHER QPF OPPORTUNITY ACROSS A
PORTION OF THE GREAT LAKES...BUT THE NATURAL DETAIL UNCERTAINTIES
REMAIN AT THIS STAGE WITH SOME PHASING ADJUSTMENTS STILL POSSIBLE
WITH AN AMPLIFYING NORTHERN STREAM WAVE TRAILING THIS FEATURE.

&&

.MARINE...

STRONG NORTHERLY WINDS IN THE WAKE OF FRIDAY COLD FRONTAL PASSAGE
AND HIGH PRESSURE BUILDING OVER THE NORTHERN PLAINS WILL KEEP THE
GRADIENT FAIRLY TIGHT OVER THE EASTERN LAKES. THIS SETUP WILL
CONTINUE TO PRODUCE GALE FORCE WINDS OVER THE SOUTH END OF LAKE
HURON THROUGH THIS AFTERNOON.  OUTSIDE OF THE GALE WARNING, SMALL
CRAFT ADVISORIES WILL BE IN EFFECT FOR ALL OTHER MARINE AREAS.

STRONG HIGH PRESSURE WILL SETTLE ACROSS THE CENTRAL PLAINS AND
MIDWEST TODAY AND SUNDAY AS ANOTHER SURGE OF ARCTIC AIR MOVES OVER
THE GREAT LAKES. THE RESULTING PRESSURE GRADIENT WILL PRODUCE
NORTHWEST GALES OVER THE NORTHERN TWO THIRDS OF LAKE HURON OPEN
WATERS THROUGH SUNDAY AFTERNOON BEFORE A MODERATING TREND BEGINS
MONDAY. GALE WARNING HAS BEEN ISSUED FOR THOSE AREAS ALONG WITH
SMALL CRAFT ADVISORIES FOR THE SOUTHERN NEARSHORE WATERS DUE TO HIGH
WAVES.

.AVIATION...ISSUED 1155 PM EST FRI FEB 10 2012

//DISCUSSION...

A POWERFUL ARCTIC COLD FRONT HAS MADE ITS WAY THROUGH THE TAF SITES.
CONDITIONS ARE STILL LIFR/VLIFR EARLY THIS MORNING FROM KFNT SOUTH
TO THE METRO AIRPORTS...HOWEVER CONDITIONS ARE QUICKLY IMPROVING
FROM NORTH TO SOUTH AS THE LAST BANDS OF FGEN SNOW DISSIPATE AS
EVIDENCED BY THE WARMING IR CLOUD TOPS AND RADAR IMAGERY. CONDITIONS
SHOULD SETTLE INTO VFR VSBYS AND MVFR CIGS AS THE SNOW
DISSIPATES...WITH NORTHWEST FLOW AND SEVERAL SHORTWAVES AND SURFACE
TROUGHS PROVIDING ENOUGH MOISTURE AND LIFT TO KEEP THE LOW CIGS IN
PLACE THROUGHOUT THE AFTERNOON AND EVENING HOURS. THE GUSTY
NORTHERLY WINDS TO 20 TO 25 KNOTS WILL BACK TO THE NORTHWEST LATER
THIS MORNING...THEN TO THE WEST DURING THE OVERNIGHT HOURS.

FOR DTW...WORST SNOW SHOULD DISSIPATE WITHIN THE NEXT FEW
HOURS...AND WILL LIKELY ONLY DROP TO 1SM WITH OCCL 1/2SM VSBYS. SNOW
RATES WILL LIKELY TOP OUT NEAR 1/2 INCH PER HOUR WITH TOTAL ACCUMS
UP TO 2 INCHES STILL EXPECTED.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN CEILING BELOW 5000 FEET THROUGH THIS AFTERNOON.

* HIGH CONFIDENCE IN SNOW AS PRECIPITATION TYPE.
