GALES...WILL LEAN TOWARD NO HEADLINE FOR GALES. INSTEAD WILL
CONTINUE TO FORECAST WINDS AROUND 30 KNOTS FOR THE DAY WITH A RANDOM
GUST TO GALE FORCE NOT OUT OF THE QUESTION...ESPECIALLY OVER SAGINAW
BAY WHICH REMAINS ICE COVERED AND ACTING MORE LIKE TERRAIN THAN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
321 AM EST THU FEB 18 2016

.DISCUSSION...

A COLD START TO THE DAY...AS TEMPERATURES GENERALLY IN THE -5 TO 10
DEGREE RANGE ACROSS SOUTHEAST MICHIGAN AT 3 AM. THIS WILL BE A DEEP
HOLE TO CLIMB OUT OF...AS HIGH PRESSURE SLOWLY EXITS SOUTHEAST
MICHIGAN...LIMITING MIXING DEPTHS. NONE-THE-LESS...WARM ADVECTION
AND MID FEBRUARY SUNSHINE SHOULD TRANSLATE TO HIGHS OF AT LEAST 30
DEGREES...WITH THE POTENTIAL TO REACH FREEZING MARK BEFORE WARM
ADVECTION MID/HIGH CLOUDS THICKEN UP. INCREASING WARM ADVECTION
TONIGHT WILL LEAD TO STEADY/SLOWLY RISING TEMPERATURES THROUGH THE
NIGHT...WITH STILL SOME DISCREPANCIES ON HOW ACTIVE THE WARM FRONT
WILL BE TRACKING THROUGH LOWER MICHIGAN...WITH THE 00Z GFS/REGIONAL
GEM BEING THE MORE ACTIVE SOLUTIONS VS DRIER NAM. THESE SIGNIFICANT
DIFFERENCES BECOME APPARENT BY 9Z FRIDAY...AS GFS 850-700 MB
SPECIFIC HUMIDITY VALUES ARE AROUND 1.5 G/KG GREATER THAN THE NAM.
LATEST 00Z EURO MORE OF A MIDDLE OF THE ROAD SOLUTION BETWEEN
TWO...AND BASED ON THE STRENGTH OF THE LOW LEVEL JET (70 KNOTS) AND
SUPPORT FROM HIRES-ARW...IT APPEARS LIKELY THERE WILL BE BRIEF SHOT
OF LIGHT PRECIPITATION ALONG/NORTH OF I-69 AROUND/JUST AFTER
MIDNIGHT...TAPERING POPS DOWN FARTHER SOUTH. WOULD EXPECT MOSTLY
SNOW WITH WET BULBING EFFECTS BEFORE WARM LAYER TAKES SUFFICIENT
HOLD TO POSSIBLY ALLOW FOR CHANGEOVER BEFORE ENDING.

ROBUST 500 MB HEIGHT FALL CENTER TO TRACK THROUGH CENTRAL WISCONSIN
FRIDAY AFTERNOON AND THROUGH NORTHERN LOWER MICHIGAN EARLY FRIDAY
EVENING. SECONDARY UPPER WAVE/HEIGHT FALL CENTER DROPPING SOUTHEAST
THROUGH MINNESOTA INTO WISCONSIN TOWARD MIDNIGHT HELPING TO
COMPLICATE THE FORECAST...ESPECIALLY WITH THE POTENTIAL WIND POP FOR
LATE FRIDAY/FRIDAY EVENING...AS 985-987 MB SURFACE LOW WEAKENS
TRACKING OFF INTO NORTHEASTERN ONTARIO FRIDAY NIGHT. LOW LEVEL
STABILITY REMAINS PROBLEMATIC/STABLE...AND STILL NO GREAT SUBSIDENCE
SIGNATURE...AND WHAT DOWNWARD TRANSPORT (280-282 K ISENTROPIC
SURFACE) THERE IS LOOKS LIKE IT WILL OCCUR AFTER 00Z SATURDAY AS MID
LEVEL DRY SLOT TAKES HOLD...WITH AREAS NORTH OF I-69 STANDING THE
BEST CHANCE OF GUSTS POSSIBLY REACHING 45 MPH. ULTIMATELY...HOW WARM
TEMPERATURES GET DURING THE DAY ON FRIDAY WILL DECIDE THE FATE OF
THE BOUNDARY LAYER DEPTH AND SUBSEQUENT WIND GUSTS AS COLD ADVECTION
SETS IN LATE IN THE DAY. EVEN THOUGH THERE LOOKS TO BE LITTLE
SUNSHINE DURING FRIDAY...WITH THE STRENGTH OF THE LOW AND EXCELLENT
LOW LEVEL WARM ADVECTION PATTERN...STILL PREFER TO GIVE MORE WEIGHT
TO THE WARMER EURO GUIDANCE...AND WILL HIGHLIGHT MAXES IN THE
UPPER 40S NORTH TO TO MID 50S SOUTH.

TIGHT NORTH-SOUTH BAROCLINIC ZONE SETTING UP OVER THE WEEKEND IN THE
LOWS WAKE ACROSS THE ACROSS THE GREAT LAKES REGION...WITH LOW
PRESSURE TRACKING THROUGH OHIO VALLEY ON SUNDAY...BRINGING GOOD
CHANCE OF PRECIPITATION WITH MID LEVEL DEFORMATION AS SHORTWAVE
TROUGH TRACKS THROUGH DURING SUNDAY EVENING. 1000-850 MB THICKNESSES
PROGGED ABOVE 1305 M ALONG/SOUTH OF M-59 THROUGH MOST OF
SUNDAY...SUGGEST RAIN...BUT TRENDING DOWN DURING THE AFTERNOON TO
SUPPORT CHANGEOVER TO SNOW BY EVENING...BUT SHORT AMPLITUDE OF UPPER
WAVE...MARGINAL THERMAL PROFILES...AND QUICK MOVING/WEAKER SURFACE
LOW SUGGESTS JUST MINOR ACCUMULATIONS.

&&

.MARINE...

LIGHT WINDS THIS MORNING WILL BECOME FRESH OUT OF THE SOUTHEAST BY
AFTERNOON AS HIGH PRESSURE DEPARTS TO THE EAST. WINDS WILL FURTHER
RAMP UP TO SUSTAINED NEAR GALES LATE TONIGHT THROUGH FRIDAY WITH
GALE GUSTS EXPECTED TO REACH 35 TO 40 KNOTS OVER THE OPEN WATERS OF
LAKE HURON. THE GALE WATCH HAS BEEN UPGRADED TO A WARNING OVER MUCH
OF THE OPEN WATERS FROM LATE TONIGHT INTO FRIDAY NIGHT. GUSTS TO
GALES WILL BECOME POSSIBLE OVER SAGINAW BAY BY FRIDAY AFTERNOON AS
LOW PRESSURE PASSES TO THE NORTH AND WINDS VEER TO THE SOUTHWEST. A
GALE WATCH WILL REMAIN IN EFFECT FOR THIS PORTION OF THE LAKE LATE
FRIDAY INTO FRIDAY NIGHT. DURING THIS PERIOD OF HIGH WINDS...EXPECT
SIGNIFICANT WAVE HEIGHTS OVER THE OPEN WATERS TO PEAK NEAR 12 FEET
WITH MAXIMUM WAVE HEIGHTS NEAR 20 FEET OVER THE NORTHERN HALF OF
LAKE HURON.

&&

.AVIATION...ISSUED 1159 PM EST WED FEB 17 2016

MSAS ANALYSES PLACE THE CENTER OF THE POLAR ANTICYCLONE OVER SAGINAW
BAY LATE THIS EVENING...WITH SURFACE OBSERVATIONS SHOWING THAT MUCH
OF SOUTHEASTERN MICHIGAN HAS GONE TO A CALM WIND. EXPECT THIS TO
CONTINUE RIGHT INTO THE MID TO LATE MORNING HOURS BEFORE SURFACE
HEATING CAN GROW A BOUNDARY LAYER. THE SURFACE WINDS WILL RESPOND
OUT OF THE SOUTHEAST DUE TO AN INCREASING GRADIENT OFF OF RETREATING
SURFACE HIGH PRESSURE. OVERRUNNING OF WARMER AND MOIST AIR WILL LEAD
TO THE ORGANIZATION OF A WARM FRONT ALOFT AND THICKENING/LOWERING OF
HIGH CLOUD BY EVENING.
