AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
310 AM EST SAT FEB 14 2015

.SHORT TERM...TODAY AND TONIGHT

CELLULAR NATURE OF RADAR ACTIVITY OVER SOUTHWEST LOWER
MICHIGAN INDICATIVE OF THE LOW LEVEL INSTABILITY...IN WHICH ARCTIC
FRONT DROPPING SOUTH WILL TAP...LEADING TO CONTINUED SNOW
SHOWERS...POSSIBLE BURST OF HEAVIER SNOW/SNOW SQUALLS ACROSS
SOUTHERN HALF OF CWA EARLY THIS MORNING...BUT STILL EXPECTING 1 TO 2
INCH RANGE TO HOLD FOR THE MOST PART...AS DRIER AIR OVER WISCONSIN
IS MAKING INROADS.

WATER VAPOR/IR SATELLITE IMAGERY SHOWS OUR ROBUST UPPER LEVEL PV
ANOMALY DESCENDING SOUTH FROM LAKE SUPERIOR EARLY THIS MORNING...AND
700 MB COLD POOL OF -35 C TO -37 C WILL BE SWINGING
THROUGH SOUTHERN LOWER MICHIGAN TODAY...WITH GOOD SURGE OF LOW
LEVEL COLD AIR FOLLOWING THE MID/UPPER LEVEL CIRCULATION TRACKING
THROUGH LAKE HURON BY SUNSET...WITH 925 MB TEMPS FALLING INTO THE
-25 TO -29 RANGE THIS EVENING/OVERNIGHT. THE ARCTIC SURFACE BOUNDARY
WILL BE CLEARING THE STATE BY MID-MORNING AS THE MAIN SURFACE LOW
OVER NORTHEASTERN ONTARIO HEADS INTO WESTERN NEW YORK. THE CURRENT
TEMPS OVER SOUTHEAST MICHIGAN...PREDOMINATELY LOWER 20S WILL BE THE
HIGHS FOR THE DAY WITH IMPRESSIVE COLD ADVECTION THROUGH THE
DAY OFFSETTING ANY INSOLATION WE RECEIVE.

POST FRONTAL SUBSIDENCE AND DEEPER MIXING WILL PROMOTE STRONG
NORTHWEST WIND GUSTS. NEED TO CLIMB ABOVE 5000 FEET TO REACH 40+
KNOTS (PER NAM SOUNDINGS)...AND EVEN THROUGH WE WILL TAP INTO
THIS LAYER...SURFACE WIND GUSTS OF COURSE WILL BE LESS...AND WILL
TOP GUSTS OUT AROUND 40 MPH. THESE STRONGER WINDS WILL LEAD TO
BLOWING SNOW...BUT WITH THE OLD CRUSTED SNOWPACK IN PLACE...AND
ONLY LIGHT ACCUMULATIONS FROM YESTERDAY EVENING AND EARLY THIS
MORNING...DECIDED AGAINST WINTER WEATHER ADVISORY.

VERY STEEP LOW LEVEL LAPSE RATES TODAY...BUT ENTIRE CLOUD LAYER
LOOKS TO BE WITHIN THE -20 TO -30 C AIRMASS...AND LOOKING FOR MOSTLY
FLURRIES FROM LATE MORNING ONWARD ONCE FRONT CLEARS THE STATE.
WILL HAVE TO KEEP AN EYE OUT FOR LAKE HURON SNOW BAND TONIGHT WITH
THE N-NW FLOW...AS 925 MB OMEGA WILL BE INTENSE...BUT 00Z
NAM/REGIONAL GEM MAINTAIN THE BAND WILL REMAIN MOSTLY OFFSHORE. WITH
MUCH OF LAKE HURON ICE COVERED...AND MOST IMPORTANTLY THE NEARSHORE
WATERS OF SOUTHERN LAKE HURON. HAVE NO COMPELLING REASON TO DISPUTE
THE DOMINANT BAND REMAINING OFFSHORE TONIGHT.

RAW SURFACE TEMPS OUT OF THE NAM/EURO INDICATING TEMPERATURES OF 10
TO 15 BELOW ZERO TOWARD SUNRISE SUNDAY...AND ALTHOUGH WINDS WILL BE
DIMINISHING STEADILY TONIGHT...ENOUGH OF A CROSSOVER OF COLD TEMPS
(ZERO TO -5) AND WIND (15 TO 20 MPH) TO SUPPORT WIND CHILLS OF 25
BELOW ZERO OR COLDER THIS EVENING AND TONIGHT...AND WILL ISSUE WIND
CHILL WARNING...WHICH WILL CONTINUE INTO SUNDAY MORNING.

&&

.LONG TERM...SUNDAY THROUGH FRIDAY

STRONGLY CONFLUENT MID LEVEL FLOW AND BUILDING SHORT WAVE RIDGING
INTO THE WESTERN GREAT LAKES WILL FORCE THE ARCTIC HIGH INTO LOWER
MI ON SUNDAY. THE MAGNITUDE OF THE COLD AIR OVERHEAD /WITH 925MB
TEMPS HOLDING AROUND -24C/ AND LIMITED AFTERNOON MIXING DEPTHS WILL
CAUSE DAYTIME HIGHS TO STRUGGLE TO SURPASS 0 DEG F. THE GRADIENT
WILL RELAX DURING THE DAY AS THE HIGH EXPANDS INTO LOWER
MI...RESULTING IN REDUCED WINDS DURING THE AFTERNOON. MODEL
SOLUTIONS HAVE BEEN STEADFAST IN SHOWING A MID LAKE CONVERGENT BAND
OF SNOW OVER SRN LAKE HURON. SFC HIGH PRESSURE SHOULD BUILD ACROSS
ONTARIO /AIDED BY THE EXCEPTIONALLY COLD AIR/ A LITTLE FASTER THAN
OVER SE MI. THIS MAY ALLOW ENOUGH OF A NE WIND COMPONENT TO FORCE
THE BAND INTO THE ERN THUMB REGION SUN MORNING/EARLY AFTERNOON. THE
FLOW SHOULD THEN BACK TO THE NW OVER SE MI IN THE AFTERNOON AS THE
SURFACE RIDGING BUILDS IN FROM THE NORTH. TEMPS HAVE THE POTENTIAL
TO DROP INTO THE NEGATIVE TEENS AND 20S SUN NIGHT. HOWEVER...THERE
IS A GOOD CHANCE THAT MID AND HIGH LEVEL CLOUDS WILL BE ON THE
INCREASE AS BROAD LOW-MID LEVEL WARM AIR ADVECTION OVERSPREADS THE
UPPER MIDWEST AND WRN GREAT LAKES. THIS SUPPORTS HOLDING WITH THE
CURRENT FORECAST MINS OF 5 TO 15 BELOW.

AMPLIFICATION OF THE LONG WAVE RIDGE ACROSS WRN NOAM AND THE NORTH
ATLANTIC WILL DRIVE ANOTHER POLAR LOW INTO HUDSON BAY BY
TUESDAY...WITH LONG WAVE TROUGHING EXPANDING BACK ACROSS THE ERN US.
THIS WILL FORCE YET ANOTHER SURGE OF ARCTIC AIR INTO THE GREAT LAKES
REGION. THE MEDIUM RANGE MODEL SUITE GENERALLY SUGGEST THE
ASSOCIATED ARCTIC FRONT TRAVERSING SE MI ON TUESDAY. WHILE MODEL
SOLUTIONS SUGGEST SOME DECENT DCVA AND GOOD MID LEVEL HEIGHT FALLS
ON TUESDAY...MEAGER MOISTURE WILL REMAIN SUPPORTIVE OF JUST CHANCE
TYPE POPS. STEADY LOW LEVEL WARM AIR ADVECTION IN ADVANCE OF THE
COLD FRONT SHOULD SEND TEMPS UP INTO THE 20S BY TUESDAY. THE PASSAGE
OF THE FRONT WILL THEN FORCE TEMPS WELL BELOW NORMAL BY WEDNESDAY...
WITH WELL BELOW NORMAL TEMPS HOLDING THROUGH THE END OF THE FORECAST
PERIOD.

&&

.MARINE...

GALE FORCE WINDS WILL RAPIDLY DEVELOP ON LAKE HURON EARLY THIS
MORNING WITH THE PASSAGE OF AN ARCTIC COLD FRONT. THE FRONT WILL
MOVE ACROSS LAKES ST CLAIR AND ERIE LATER THIS MORNING...WITH GALE
FORCE WINDS QUICKLY FOLLOWING IN THEIR WAKE. THE DEGREE OF COLD AIR
ADVANCING INTO THE REGION TODAY ALONG WITH RAPIDLY DEEPENING LOW
PRESSURE HEADING EAST OF THE GREAT LAKES WILL LEAD TO HIGH END GALE
FORCE WINDS OUT OF THE NNW ON LAKE HURON. GALES WILL PERSIST WELL
INTO TONIGHT ON LAKE HURON. WINDS WILL THEN WEAKEN DURING THE DAY
SUNDAY AS ARCTIC HIGH PRESSURE BUILDS OVERHEAD.

&&

.AVIATION...ISSUED 1202 AM EST SAT FEB 14 2015

A PATTERN OF SNOW WILL CONTINUE OVER SE MICHIGAN AHEAD OF A POWERFUL
ARCTIC COLD FRONT. INTENSITY WILL BE VARIABLE BUT IFR RESTRICTION IS
EXPECTED TO BE THE PREVAILING CONDITION SOUTH OF MBS. THE FRONT
CONTINUES TO HOLD THE POTENTIAL FOR A ROUND OF SNOW SQUALLS AS IT
MOVES NORTH TO SOUTH OVER THE REGION FROM ABOUT 09Z TO 13Z.
CONDITIONS WILL BE FAVORABLE FOR SQUALLS TO PRODUCE NEAR ZERO
VISIBILITY IN SNOW AND BLOWING SNOW AS WIND GUSTS SURGE TO 30 KNOTS
POST FRONT. THE SQUALLS WILL FOLLOW THE FRONTAL WIND SHIFT SOUTH OF
THE AREA BUT THE WIND WILL CONTINUE SUSTAINED 20-25 KNOTS WITH GUSTS
30-35 KNOTS THROUGH THE AFTERNOON. THIS WILL MAINTAIN BLOWING SNOW
BUT THE ARCTIC AIR WILL BECOME TOO DRY FOR MUCH MORE THAN FLURRIES
BEFORE A CLEARING CLOUD TREND INTO SATURDAY EVENING. DANGEROUS WIND
CHILL WILL BE THE PRIMARY CONCERN.

FOR DTW... IFR VISIBILITY IN SNOW SHOWERS WILL OCCUR OFF AND ON
DURING THE REST OF THE NIGHT BUT ONLY LEAVE LESS THAN AN INCH OF
POWDERY ACCUMULATION. THIS WILL BE FOLLOWED BY A POWERFUL ARCTIC
FRONT AROUND 13Z. CONFIDENCE IS GOOD ON THE FRONTAL TIMING AND
POTENTIAL FOR SNOW SQUALLS FOR 2-3 HOURS TRAILING THE PASSAGE THAT
COULD REDUCE VISIBILITY NEAR ZERO AT TIMES AND PRODUCE ANOTHER QUICK
INCH OF ACCUMULATION. WIND GUSTS WILL THEN BUILD UP TO 35 KNOTS BY
AFTERNOON LEAVING THE WIND AND DANGEROUSLY COLD WIND CHILL AS THE
PRIMARY CONCERN THROUGH SATURDAY EVENING.

//DTW THRESHOLD PROBABILITIES...

* HIGH FOR CEILINGS BELOW 5KFT TONIGHT THROUGH MORNING.

* HIGH FOR PRECIPITATION TYPE OF SNOW.

* MODERATE FOR EXCEEDING CROSSWIND THRESHOLD DUE TO GUSTS NEAR 35
  KNOTS FROM 330 DIRECTION.
