LAKE HURON. MODEL SOUNDING FROM N CENTRAL LAKE HURON HAVE US MIXING 
DOWN FROM 4KFT WHERE 37KT WINDS COULD OCCUR. ENHANCING THE WINDS AS 
WELL WILL BE A 500MB TROUGH AXIS AND 35KT 850MB JET PASSING THROUGH 
FROM 00-06Z TONIGHT. WILL KEEP GALES IN THE FORECAST JUST UNTIL THE 
ABOVE FEATURE PASSES AND THE PRESSURE GRADIENT RELAXES SOME...AROUND 
09Z. 

CONTINUED STRONG SW WINDS PROVIDE AN INTERESTING FEATURE SHOWN ON 
VIS SATELLITE TODAY AS ICE SHELF MOVED SIGNIFICANTLY AWAY FROM LAND.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1200 AM EST THU FEB 3 2011

.AVIATION...

OBSERVATIONS INDICATE CEILING HEIGHT ALONG THE SHORELINE OF LAKE
MICHIGAN HAS DROPPED INTO THE MVFR CATEGORY WITH AN INLAND MOVE IN
THE PATTERN AS WINDS BACK TOWARD THE WEST. PLAN TO GIVE THESE CLOUDS
A CHANCE TO MAKE IT INTO OUR AREA LATER IN THE MORNING AS WESTERLY
FLOW CONTINUES TO DEVELOP AND THE INVERSION ABOVE THE BOUNDARY LAYER
INCREASES. HOWEVER, PLAN NOT TO CARRY A PREVAILING CONDITION AS
THERE IS LITTLE OR NO ADDITIONAL LAKE CLOUD DEVELOPMENT DUE TO THE
VERY DRY AIR FROM WISCONSIN. THIS LACK OF NEW CLOUD DEVELOPMENT ADDS
SOME DOUBT ABOUT HOW MUCH WILL BE LEFT OF THE OVERALL PATTERN BY THE
TIME IT REACHES SE MICHIGAN.

THE OTHER CONCERN FOR AVIATION INTERESTS WILL BE WITH SOUTHWEST WIND
INCREASING THIS AFTERNOON. GUSTS OF 20 TO 25 KNOTS WILL ADD AN EDGE
TO ALREADY COLD TEMPERATURES. ANY ADDITIONAL LAKE-GENERATED CLOUD
COVER LATER TODAY IS EXPECTED TO BE PATCHY DUE TO THE DRY NATURE OF
THE BOUNDARY LAYER AND DIRECTED MOSTLY NORTH OF MBS. THE GUSTINESS
OF THE WIND WILL EASE A BIT THIS EVENING BUT SUSTAINED WIND WILL
LINGER NEAR 15 KNOTS THROUGH TONIGHT.

&&

.PREV DISCUSSION...ISSUED 308 PM EST WED FEB 2 2011

SHORT TERM...TONIGHT

SNOW AND WINDS CONTINUE TO WIND DOWN LATE THIS AFTERNOON...WITH JUST
SOME LINGERING LAKE EFFECT ACTIVITY WITH THE NORTHERLY FLOW COMING
OFF LAKE HURON TO DEAL WITH...WHICH WILL LIKELY AFFECT THE SHORELINE
COMMUNITIES OF THE THUMB REGION EARLY THIS EVENING BEFORE PUSHING
OFFSHORE AND ENDING...AS LOW LEVEL ANTI-CYCLONIC FLOW BUILDS IN AND
SURFACE RIDGE AXIS SETTLES OVER THE CENTRAL GREAT LAKES TOMORROW
MORNING. THUS...WITH SOME ADDITIONAL LIGHT SNOW SHOWER ACTIVITY AND
CONTINUED BRISK WINDS OF 25 TO 35 MPH FOR ANOTHER FEW HOURS...WILL
CARRY BLOWING SNOW ADVISORY FOR HURON/SANILAC INTO THE MID EVENING
HOURS. ALL OTHER HEADLINES WILL BE ALLOWED TO EXPIRE AT 5 PM.

WITH CLEARING SKIES EXPECTED TONIGHT...WE ARE SET UP FOR A
COLD NIGHT WITH THE FRESH SNOW COVER...AND WILL CONTINUE WITH THE
MINS IN THE LOW SINGLE NUMBERS...SEVERAL DEGREES BELOW LATEST
GUIDANCE. IF THERE WASN'T SOME UNCERTAINTY WITH WINDS COMPLETELY
DYING OFF BY 12Z...WOULD HAVE FORECASTED MINS BELOW ZERO ACROSS MUCH
OF THE CWA.

LONG TERM...THURSDAY THROUGH WEDNESDAY

IN THE WAKE OF THE DEPARTING STORM SYSTEM...SURFACE HIGH PRESSURE
WILL EXTEND FROM THE TEXAS INTO THE OHIO/TENNESSEE VALLEY REGIONS.
THIS WILL PROVIDE SEVERAL DAYS OF QUIET WEATHER. TEMPERATURES WILL
BE RATHER CHILLY WITH THIS LARGE COLD AIRMASS ENCOMPASSING MUCH OF
THE EASTERN CONUS...WITH HIGHS AROUND 20 DEGREES AND LOWS IN THE
SINGLE DIGITS TO AROUND ZERO.

THE NEXT SYSTEM TO AFFECT THE AREA WILL BE A NORTHERN STREAM WAVE
THAT WILL SWEEP INTO THE UPPER MIDWEST/GREAT LAKES DURING THE LATE
FRIDAY INTO SATURDAY TIME FRAME. THIS SYSTEM WILL INTERACT TO SOME
DEGREE WITH THE LEFTOVER UPPER LEVEL ENERGY NOW SETTLING INTO THE
SOUTHWEST CONUS. A LION/S SHARE OF THE 12Z MODEL SOLUTIONS...WHICH
INCLUDES GFS/GLOBAL GEM ENSEMBLE MEMBERS...ARE PROGRESSIVE ENOUGH
WITH THE NORTHERN STREAM WAVE TO LIMIT THE EFFECTS OF ANY PHASING
BETWEEN THE STREAMS TO AREAS GENERALLY EAST OF THE CENTRAL GREAT
LAKES. SO...GENERALLY DO NOT EXPECT ANYTHING MORE THAN LIGHT SNOW
FOR SOUTHEAST LOWER MICHIGAN ATTM.

ADDITIONAL SHORTWAVE ENERGY CONTINUES TO STREAM OFF THE NORTHERN
PACIFIC INTO THE BASE OF THE STEADILY AMPLIFYING UPPER TROUGH OVER
THE UPPER MIDWEST. THIS WILL PUT THE REGION WITHIN AN UNSETTLED
PATTERN WITH PERIODS OF LIGHT SNOW NEXT WEEK. THERE IS STILL SOME
CONCERN THAT ENOUGH PHASING BETWEEN THE MOST SIGNIFICANT OF THESE
GULF/ALASKA SHORTWAVES AND SHORTWAVE ENERGY ROTATING AROUND THE
HUDSON BAY POLAR VORTEX WILL PRODUCE A MORE SUBSTANTIAL SYSTEM
THROUGH OR JUST EAST OF THE CENTRAL GREAT LAKES DURING THE MONDAY
INTO TUESDAY TIME FRAME. MODEL CONSISTENCY REMAINS IFFY ON THE
EVOLUTION OF THIS PARTICULAR STORM SYSTEM ATTM...WHICH IS NOT
SURPRISING GIVEN THE FAST ENERGETIC FLOW STREAM DOWN FROM THE
NORTHERN PACIFIC. SO...FORECAST CONFIDENCE...BEYOND THE GENERAL
UPPER LEVEL PATTERN...REMAINS LOW AT THIS POINT.

TEMPERATURES WILL REMAIN COLD INTO NEXT WEEK...AND WILL LIKELY GET
COLDER AT THE END OF THIS FORECAST PERIOD AS THE AMPLIFYING UPPER
TROUGH INTO EARLY NEXT WEEK WILL FEED ADDITIONAL POLAR/ARCTIC AIR
INTO THE GREAT LAKES BY TUESDAY/WEDNESDAY

MARINE...

WINDS WILL QUICKLY DIMINISH THIS EVENING AS A RIDGE OF HIGH PRESSURE
MOVES OVER THE CENTRAL GREAT LAKES LATE TOMORROW MORNING. THIS HIGH
WILL SLIDE EAST THROUGH THE END OF THE WORK WEEK...SUPPORTING
MODERATE SOUTHWEST WINDS OF 15 TO 25 KNOTS. WINDS WILL BECOME
LIGHTER OVER THE WEEKEND...AREA OF LOW PRESSURE WORKS THROUGH THE
REGION.
