AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
628 AM EST SAT FEB 27 2016

.AVIATION...

EDGE OF STRATUS DECK IS STEADILY MOVING EAST EARLY THIS MORNING WITH
THE BACK EDGE OF THE DECK ALMOST THROUGH ALL THE TAF SITES.  AS
DRIER AIR WORKS IN ANY LOWER VFR CLOUDS WILL MOVE OFF BRINGING VFR
CONDITIONS TO ALL THE TERMINALS AS RIDGE OF HIGH PRESSURE BUILDS IN
OVER THE AREA.  SOUTHWESTERLY FLOW PREVAILS TODAY AS WINDS START TO
INCREASE THROUGHOUT THE DAY AND AGAIN TOMORROW AS THE NEXT LOW
PRESSURE SYSTEM MOVES TOWARDS THE AREA.

FOR DTW...EDGE OF LOWER VFR CLOUD DECK TODAY WILL QUICKLY PASS OVER
THE TERMINAL AND AS IT DOES WINDS WILL INCREASE DURING THE DAY.  AN
INCREASED GRADIENT AND DEEPENING DAYTIME MIXED LAYER WILL SUPPORT
GUSTY SOUTHWEST WINDS ON SATURDAY...WITH GUSTS POSSIBLY REACHING 30
KNOTS.

//DTW THRESHOLD PROBABILITIES...

* HIGH IN CEILINGS ABOVE 5000FT TODAY.

&&

.PREV DISCUSSION...ISSUED 411 AM EST SAT FEB 27 2016

DISCUSSION...

STRONG LOW TO MIDLEVEL WARM ADVECTION WILL SUPPORT MIDLEVEL RIDGING
THROUGH THE CENTRAL GREAT LAKES TODAY. THE WARM ADVECTION OFF OF THE
DECK WILL SUPPORT A STABLE COLUMN AND PRECIPITATION FREE CONDITIONS.
THE ITEM OF IMPORTANCE IS REALLY HOW HIGH MIXING DEPTHS CAN GET
TO IN LIGHT OF THE FRESH SNOWPACK. THE ANSWER TO THIS HAS
IMPORTANCE ON BOTH HIGH TEMPERATURES AND SURFACE WIND MAGNITUDES
TODAY. IT IS A DIFFICULT CALL AS FORECAST SOUNDINGS DIFFER RATHER
SIGNIFICANTLY ON THE STRUCTURE AND DEPTH OF THE BOUNDARY LAYER.
ADDING TO THE CONFUSION IS THE LOW RESOLUTION ECMWF FORECAST
SOUNDINGS AVAILABLE SUGGESTING LITTLE TO NO BOUNDARY LAYER GROWTH
WILL OCCUR. THERE IS SOME SIGNAL SUGGESTING THE TERRAIN WILL
REMAIN COOLER...WHICH IS PROBABLY A GOOD CALL GIVEN THE ELEVATION
FACTOR AND IT IS THE SAME AREA THAT OBSERVED THE HIGHEST RECENT
SNOW AMOUNTS. THE FORECAST CALLS FOR LOWER 40S FOR MANY AREAS.
WITH THE ARCTIC FRONT APPROACHING NORTHERN LAKE SUPERIOR
TODAY...THE STRENGTH AND STRUCTURE OF THE MSLP GRADIENT OVER THE
AREA IS RATHER IMPRESSIVE. 925 MB WINDS TODAY ARE SHOWN TO REACH
IN EXCESS OF 30 KNOTS. THE OUTGOING FORECAST CALLS FOR SOUTHWEST
WINDS OF 20 TO 30 MPH.

MODELS CONTINUE TO ADVERTISE A COMPACT SURFACE LOW PRESSURE SYSTEM
DEVELOPING/UNDERGOING CYCLOGENESIS OVER THE GREAT LAKES REGION
SUNDAY AND SUNDAY NIGHT. THERE IS A GOOD CONSENSUS THE SURFACE LOW
WILL TRACK ALONG THE SOUTHERN PERIPHERY OF THE ARCTIC FRONT...FROM
SHEBOYGAN WI AT 18Z SUNDAY TO ALONG SAGINAW BAY/CENTRAL LAKE HURON
BY 00Z MONDAY. THE PRIMARY FORCING AT WORK WITH THE DEEPENING
SURFACE LOW APPEARS TO BE VERY STRONG RIGHT ENTRANCE REGION
DYNAMICS ALOFT. FGEN AND COLD SIDE DEFORMATION IS PROGGED TO BE
GOOD...HOWEVER...REMAINS WELL NORTH OF THE AREA. SO GIVEN THE DRY
POLAR ORIGIN AIRMASS IN ADVANCE OF THE SYSTEM...THE OVERALL
PRECIPITATION POTENTIAL IS ON THE LOWER SIDE. KEPT WITH THE LIKELY
POPS CENTERED AROUND SUNDAY EVENING...FOR LIGHT
RAIN...TRANSITIONING TO SNOW FLAKES SUNDAY NIGHT. LITTLE SNOW
ACCUMULATION IS EXPECTED ATTM...BUT THE ONE AREA THAT COULD SEE
SOME LIGHT ACCUMULATIONS WOULD BE IN THE THUMB. THE MAIN TOPICS
FOR THE SUNDAY SYSTEM REMAIN WHAT DAYTIME TEMPERATURES CAN GET
TO...AND MORE IMPORTANTLY THE WIND POTENTIAL. PREFER TO SEE WHAT
THE TEMPERATURE AND SNOWPACK RESPONSE IS TODAY BEFORE HIKING
TEMPERATURES UP SIGNIFICANTLY. ECMWF MOS GUIDANCE IS STILL
ADVERTISING 60S WHICH WOULD BE AN EASY CALL IF THERE WASN'T THE
SNOWPACK. IF IT WERE TO OCCUR...PROBABLY VERY LATE SUNDAY
AFTERNOON/VERY EARLY SUNDAY EVENING JUST AHEAD OF THE SURFACE COLD
FRONT. AS FOR WINDS...THE ONE NOTABLE TREND IN LATEST FORECAST
DATA IS ONE OF A BROADER SURFACE LOW CIRCULATION IN PLACE ACROSS
SOUTHEASTERN MICHIGAN SUNDAY AFTERNOON. SO DESPITE...HIGHLY
IMPRESSIVE 850MB WINDS OF 60 KNOTS OR MORE...TRULY STRONG 925 MB
WINDS ARE RELEGATED TO THE PERIPHERY NEAR/LAKE ERIE/LAKE ST CLAIR.
INCIDENTALLY...THE SAME AREAS THAT DID NOT GET AS MUCH SNOW.
CONTINUED TO MENTION WINDS OF 35 TO 40 MPH POSSIBLE...PRIMARILY
OVER THE SOUTHERN HALF OF THE CWA SUNDAY AFTERNOON AND SUNDAY
EVENING.

NO NEW INFORMATION PRESENTED ITSELF WITHIN THE 27.00Z NWP DATA TO
BACK OFF OF THE OUTLOOK FOR A POTENTIAL WINTER WEATHER STORM
SYSTEM DURING THE TUESDAY/TUESDAY NIGHT TIMEFRAME. AT THESE LEAD
TIMES...THE MESSAGE IS INEVITABLY THE SAME...HIGHLIGHTING THESE
EVENTS AS COMPLEX AND UNCERTAIN. THE COMPLEXITY FOR THIS EVENT IS
TIED TO THE DOWNSTREAM EVOLUTION/TIMING OF TWO SEPARATE SHORTWAVE
PV FEATURES. THE FIRST ONE IS NOW EMBEDDED ALONG THE POLEWARD
FLANK OF A ZONAL CENTRAL PACIFIC JET STREAK. THE SECOND SHORTWAVE
IS NOW MIRED WITHIN A LARGER POTENTIAL VORTICITY ENVELOPE NEAR
70N 68W. THE LATTER UPPER LEVEL LOW CIRCULATION IS FORECASTED TO
SWING/PIVOT DOWN ACROSS NORTHERN LAKE SUPERIOR/NORTH OF LAKE HURON
MONDAY. PLENTY OF INTERACTIONS NEED TO OCCUR YET WITH BOTH
FEATURES. WHAT IS PROBABLY THE MOST IMPORTANT OFF OF THE SECOND
SHORTWAVE IS EXACTLY HOW FAR SOUTHWARD AN ARCTIC SURFACE FRONT
WILL PUSH MONDAY NIGHT. SAMPLING OF THE MID- LATITUDE PACIFIC
ENERGY THAT EVENTUALLY RESULTS IN THE TUES/WED LOW PRESSURE SYSTEM
WILL NOT HAVE A TAIL OF THE PV FILAMENT SAMPLED IN THE PACNW
UNTIL THE 12Z MONDAY RAOB. PREFERENCE AT THIS POINT REMAINS WITH
THE MORE CONSISTENT ECMWF...WHICH CONTINUES TO SUGGEST THE
POTENTIAL FOR SOME SIGNIFICANT SNOW ACCUMULATIONS FOR AT LEAST A
SIZABLE PORTION OF THE CWA (AGAIN GLACIAL TERRAIN NORTHWARD). THE
ECMWF SOLUTION DOES SUPPORT SUB FREEZING SURFACE WET BULB
TEMPERATURES TUESDAY AHEAD OF THE SYSTEM MOISTURE.

MARINE...

RIDGE OF HIGH PRESSURE WILL HOLD ACROSS THE MARINE AREAS THROUGH
TONIGHT RESULTING IN A CONTINUATION OF DRIER CONDITIONS.
SOUTHWESTERLY FLOW WILL INCREASE TODAY AND EVEN MORE TOMORROW AS
WARMER AIR SURGES INTO THE REGION.  WIND GUST ACROSS THE MARINE
AREAS WILL REACH INTO THE 25 TO 30 KNOT RANGE TODAY.  AS THE NEXT
LOW PRESSURE SYSTEM APPROACHES...A TIGHTENING PRESSURE GRADIENT WILL
BRING THE CHANCE FOR GALES ACROSS LAKE HURON.  THIS HAS RESULTED IN
AN ISSUANCE OF A GALE WATCH ACROSS LAKE HURON FOR SUNDAY.  RAIN AND
SNOW WILL AFFECT THE REGION SUNDAY NIGHT AS A COLD FRONT PASSES
THROUGH.  THIS FRONT WILL SHIFT SOUTHWESTERLY WINDS BACK TO THE
NORTHWEST DURING THE OVERNIGHT HOURS ON SUNDAY.
