AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
1235 PM EST SUN JAN 14 2007

.UPDATE...HAVE OBVIOUSLY DECIDED TO PUT A PORTION OF THE CWA IN A
WINTER STORM WATCH FOR OVERNIGHT THROUGH MONDAY MORNING. HAVE
ESSENTIALLY FOCUSED ON PORTIONS OF NORTHEAST LOWER MICHIGAN WHERE
LAKE ENHANCEMENT OFF LAKE HURON MAY BOOST SNOW ACCUMULATIONS BETWEEN
MIDNIGHT AND NOON MONDAY INTO WARNING CRITERIA (6 INCHES/12 HOURS).
MAY ALSO BE HOISTING ADVISORIES FOR ADDITIONAL COUNTIES NEAR THE
WATCH...TIER OF COUNTIES ALONG THE M-55 CORRIDOR FROM MANISTEE TO
ROSCOMMON AND PERHAPS ADDITIONAL NE COUNTIES AROUND THE WATCH.

ADAM

.PREV DISCUSSION...ISSUED AT 1037 AM EST SUN JAN 14 2007

UPDATE...SFC ANALYSIS REVEALING WEAK NEARLY INDISCERNIBLE COLD
FRONT ACROSS THE UPPER PENINSULA AND ACROSS CENTRAL WISCONSIN...
WHILE HIGH PRESSURE ONCE AGAIN BUILDING SE OUT OF CANADA AND INTO
NRN MICHIGAN. PER 12Z APX SOUNDING...NOT NEARLY AS SATURATED IN THE
LOWER AND MID LEVELS ACROSS THE CWA THIS MORNING AS WAS INDICATED
YESTERDAY WITH BASICALLY SCT-BKN LOW AND MID CLOUD COVER OUT THERE
THIS MORNING. SO ASIDE FROM A COUPLE POCKETS OF LIGHT SNOW RUNNING
ACROSS THE SOUTHERN TIER OF COUNTIES LAST EVENING AND OVERNIGHT...
PRETTY MUCH HIGH AND DRY CURRENTLY ACROSS THE CWA.

FOR THE REST OF THE AFTERNOON...WITH COLDER BUT DRYER AIR GETTING
SLOWLY SUPPRESSED SOUTHWARD AND LOW LEVEL WINDS VEERING TO THE
N/NW...SHOULD EVENTUALLY GET SOME LIGHT LAKE EFFECT SNOW SHOWERS
GOING DURING THE AFTERNOON. BEST CHANCES LOOKING TO BE AROUND
WHITEFISH POINT...AND AREAS AROUND GRAND TRAVERSE BAY.
HOWEVER...FAIRLY LOW AND STRONG INVERSION HEIGHTS COMBINED WITH
DRYING AND MARGINALLY COLD TEMP PROFILES WILL KEEP LES COVERAGE AND
INTENSITY AT BAY.

BIGGER FORECAST CONCERN COMES OVERNIGHT THROUGH MONDAY MORNING. 06Z
AND 12Z NAM-WRF SOLUTIONS HAVE OF COURSE BEEN TRENDED THIS STORM
NORTHWARD AND STRONGER...TAKING THE SFC LOW UP THROUGH CLEVELAND
MONDAY MORNING AND NOW PRODUCING A DECENT SWATH OF 0.50 TO 0.75
INCHES OF QPF ACROSS THE S/E PORTION OF THE CWA THROUGH MONDAY
EVENING. IF CORRECT...AND CONSIDERING LAKE ENHANCEMENT POTENTIAL OFF
LAKE HURON...THIS SUGGESTS 5 TO 10 INCHES OF ACCUMULATION POTENTIAL
FOR THESE AREAS BASICALLY IN A 12 HOUR WINDOW FROM MIDNIGHT TONIGHT
THROUGH NOON MONDAY. DTX/GRR HAVE ALREADY EXPANDED WATCH
ACCORDINGLY. AM ALSO CONSIDERING PUTTING SRN TIER OF COUNTIES AND
PORTIONS OF NE LOWER MICHIGAN INTO A WATCH AS WELL EITHER WITH THE
MORNING UPDATE OR EARLY IN THE AFTERNOON. WOULD REALLY LIKE TO GET A
GOOD LOOK AT OTHER 12Z GUIDANCE AS WELL AS DO A BIT MORE REAL-TIME
ANALYSIS TO BEFORE MAKING JUMPING IN.

ADAM

.PREV DISCUSSION...ISSUED AT 325 AM EST SUN JAN 14 2007

DISCUSSION...OVERALL FORECAST BEGINNING TO COME INTO GREATER
CLARITY THROUGH EARLY IN THE WEEK AS NORTHERN STREAM ENERGY AND
SOUTHERN STREAM MOISTURE IMPACT MICHIGAN.  MAIN WEATHER FEATURE WILL
OCCUR LATER SUNDAY NIGHT INTO MONDAY...AS SURFACE LOW TRACKS ACROSS
THE OHIO VALLEY WHILE NORTHERN STREAM SHORTWAVE TROF PUSHES ACROSS
THE GREAT LAKES.  BIGGEST FORECAST QUESTION WILL REVOLVE AROUND
TRYING TO SORT OUT TO WHAT DEGREE DRY AIR ADVECTING IN FROM THE
NORTH WILL IMPACT SNOW/QPF INCREASING FROM THE SOUTH.

TODAY...RATHER BENIGN WINTER WEATHER ACROSS NORTHERN MICHIGAN TODAY.
1000-850MB WIND FIELDS REMAIN QUITE LIGHT...AND GRADUALLY WILL VEER
FROM NORTHWEST THIS MORNING TO NORTH THIS AFTERNOON.  WEAK DYNAMICS
AT PLAY TODAY...WITH FGEN BAND ACROSS SOUTHERN PARTS OF THE AREA BUT
MOISTURE DEPTH SHALLOW AND DRY AIR IN THE MID LEVELS.  FORECAST
SOUNDINGS SHOW MOST OF THE MOISTURE BELOW THE -10 DEGC LINE...SO A
LOW QPF EVENT.  WE MAY BE ABLE TO DEVELOP SOME LIGHT LAKE EFFECT
SNOW SHOWERS AS THE DAY PROGRESSES...ALTHOUGH LOW INVERSION HEIGHTS
AND DRY MID LEVELS WILL KEEP THINGS IN CHECK.  ANY SNOW
ACCUMULATIONS SHOULD BE LESS THAN ONE INCH.

TONIGHT/MONDAY...THE MAIN WEATHER STORY WILL PLAY OUT DURING THIS
TIMEFRAME.  SURFACE LOW WILL TRACK TO THE NORTHEAST ALONG
QUASI-STATIONARY FRONT POSITIONED ACROSS THE OHIO VALLEY.  BOTH THE
NAM AND GFS HAVE TRENDED A BIT FURTHER NORTH WITH THE SURFACE LOW
TRACK AND IT/S ASSOCIATED MOISTURE OVER THE PAST 2 RUNS.
NORMALLY...A SURFACE LOW TRACKING AS FAR SOUTH AS THIS ONE WOULD NOT
PRODUCE MUCH IN THE WAY OF SNOW ACROSS NORTHERN MICHIGAN...BUT IN
THIS CASE WE ALSO HAVE A VIGOROUS NORTHERN STREAM SHORTWAVE TROF
APPROACHING THE GREAT LAKES.  NAM CROSS SECTIONS DRAWN FROM NORTH TO
SOUTH ACROSS THE AREA /COLD AIR TO WARM AIR/ SHOW AN FGEN BAND
MOVING INTO NORTHERN LOWER MICHIGAN TOWARD 12Z MONDAY.  SATURATED
EQUIVALENT POTENTIAL TEMPERATURES ARE SLIGHTLY BELOW ZERO JUST ABOVE
THIS SLOPED FGEN AREA ACROSS MUCH OF NORTHERN LOWER BETWEEN
09Z-15Z.  THIS WOULD NORMALLY POINT TOWARD A HEAVIER SNOW AREA...BUT
WE HAVE AN INHIBITING FACTOR TO CONSIDER...MOISTURE DEPTH.  LOW
LEVEL NORTHEAST FLOW WILL BE ADVECTING IN DRIER AIR DURING THIS
TIME...RESULTING IN THE ATMOSPHERE HAVING TO FULLY MOISTEN UP.  SO
THE REAL QUESTION IS...WILL THE DELAY IN MOISTENING UP THE
ATMOSPHERE WASTE SEVERAL HOURS OF THE BEST DYNAMICS.  I THINK THE
ANSWER TO THIS IS YES...ESPECIALLY NORTH OF M-72.  THE MOISTURE
DEPTH NEVER REALLY GETS TO THE LEVEL WHERE I WOULD LIKE TO SEE FOR A
BIG SNOW EVENT...AS WE NEVER SEE A SEVERAL HOUR PERIOD WITH PRIME
TEMPERATURES IN THE -12 TO -18 DEGC RANGE WITHIN THE DEEPER
MOISTURE.  SO ALL OF THIS POINTS TO A WIDESPREAD SNOW EVENT IN
NORTHERN MICHIGAN WITH GENERALLY SMALLER FLAKE SIZE RESULTING IN
LOWER SNOW TOTALS.  WE WILL SEE SOME ENHANCEMENT OFF OF LAKE HURON
...ESPECIALLY BETWEEN ROGERS CITY AND EAST TAWAS...AND THIS
AREA COULD SEE 1-2 INCHES MORE OF ACCUMULATION THAN AREAS FURTHER
NORTH AND WEST.  AS SURFACE LOW PASSES TO THE SOUTHEAST DURING THE
AFTERNOON...LOW LEVEL FLOW BACKS TO THE NORTH...AND WE MAY ALSO SEE
SOME SNOW ENHANCEMENT OFF OF LAKE MICHIGAN /MAINLY WEST OF US-131/.
I WILL PAINT A GENERAL 2-3 INCH SNOWFALL FOR MOST AREAS OF NORTHERN
LOWER /EXCEPT THE ENHANCED AREAS/...WITH LIGHTER AMOUNTS AS YOU HEAD
NORTH INTO EASTERN UPPER.

NORTH TO NORTH NORTHWEST LAKE EFFECT DEVELOPING MONDAY NIGHT...AND A
FEW MORE INCHES OF ACCUMULATION POSSIBLE IN THOSE FAVORED LAKE
EFFECT AREAS /ESPECIALLY ALONG AND WEST OF US-131/.

JK

TUESDAY NIGHT THROUGH THURSDAY...ECMWF AND GFS APPEAR TO BE IN
REASONABLE AGREEMENT WITH REGARDS TO THE MOISTURE FIELDS THROUGH
THIS PERIOD...WHILE THE NAM SITS AS THE OUTLIER. GFS/ECMWF HAVE
RELATIVE HUMIDITY IN THE 850-700MB DROPPING OFF TO LESS THAN 25% BY
TUESDAY NIGHT ACROSS NORTHERN MICHIGAN...WHILE THE NAM IS MUCH
SLOWER AND KEEPS THE DECENT MOISTURE (>70%) AROUND MUCH LONGER. AS
IS THE CASE IN NORTHERN MICHIGAN QUITE FREQUENTLY...MODELS HAVE A
TENDENCY TO END LAKE EFFECT TOO QUICKLY...SO THE SLOWER DECREASE IN
MOISTURE DEPICTED BY THE NAM MIGHT BE THE MORE LIKELY SCENARIO...
WHICH WOULD KEEP LAKE EFFECT PRECIPITATION GOING THROUGH TUESDAY
NIGHT. REGARDLESS...WILL HOLD OFF ON INTRODUCING POPS BACK INTO THE
FORECAST TO AVOID FLIP FLOPPING WITH CHANCE POPS AND LET THE
DAY SHIFT TAKE A SECOND LOOK. OTHERWISE...AS RIDGE AXIS MOVES
OVERHEAD WEDNESDAY...TRANQUIL WEATHER WILL RETURN FOR THE MIDDLE
HALF OF THE WEEK. WITH 850MB TEMPS SHOWING VERY LITTLE
RECOVERY...MAY KEEP SOME CLOUDINESS NEAR THE LAKE SHORES...BUT
OTHERWISE...MANY AREAS WILL SEE SOME SUN FOR THE MIDDLE OF THE WEEK.
TEMPERATURES TUESDAY AND WEDNESDAY NIGHTS WILL BE SOME OF THE COLDEST
OF THE SEASON SO FAR...WITH LOWS EXPECTED TO REACH THE SINGLE
DIGITS. A FEW AREAS MAY EVEN SEE SUB-ZERO TEMPERATURES...ESPECIALLY
INLAND AREAS...WITH THE LACK OF CLOUD COVER. HIGHS WILL ALSO BE
QUITE CHILLY WITH TEMPERATURES STRUGGLING TO GET OUT OF THE TEENS.
