...GALES TO IMPACT THE REGION TONIGHT AND SUNDAY...

.A RAPIDLY DEEPENING LOW PRESSURE SYSTEM WILL PUSH A COLD FRONT 
ACROSS THE CENTRAL GREAT LAKES TONIGHT. THIS WILL ALLOW STRONG WEST 
WINDS TO DEVELOP TONIGHT AND CONTINUE INTO SUNDAY AS THE SURFACE

INCREASE TO 40 KNOTS GALES TOMORROW. GALE FORCE WIND GUSTS WILL 
SUBSIDE ACROSS MOST OF THE AREA SUNDAY EVENING AS THE LOW PRESSURE 
SYSTEM MOVES AWAY AND A RIDGE OF HIGH PRESSURE BUILDS IN FROM THE 
WEST. GALE FORCE WIND GUSTS WILL HOWEVER LINGER OVER THE NORTHERN 
HALF OF LAKE HURON...CLOSER TO THE DEPARTING AREA OF LOW

GUSTS TO 40 KNOT GALES HAVE BEEN WIDESPREAD THIS AFTERNOON...WITH 
GUSTS TO 45 KNOTS OVER THE OPEN WATERS OF LAKE HURON NORTH OF 
ALPENA. THE STRONG PERSISTENT WINDS WILL ALSO CREATE LOW WATER

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1047 PM EDT FRI APR 15 2011

.UPDATE...

OBSERVATIONAL EVIDENCE OF APPRECIABLE CONVECTION TO OUR WEST
WARRANTED ADDITION OF A CHANCE OF THUNDER TO THE FORECAST
OVERNIGHT, MAINLY ALONG AND SOUTH OF INTERSTATE 69 FOR NOW.
OUTSTANDING LOW LEVEL MOISTURE TRANSPORT IS IN PROGRESS OVER THE
REGION AS SHOWN BY MODEL DEPICTIONS OF A 60 KNOT LOW LEVEL JET
CENTERED AROUND 850 MB. THE DESTABILIZATION ASSOCIATED WITH THIS
PROCESS WILL CONTINUE TO SUPPORT WIDESPREAD SHOWER DEVELOPMENT
WITH A FEW POCKETS OF THUNDER POSSIBLE. LATER TONIGHT, THE
ADVANCING UPPER LOW WILL SPREAD COLDER AIR ALOFT OVER LOWER
MICHIGAN TO STEEPEN LAPSE RATES EVEN FURTHER. NO SEVERE WEATHER.
THE REST OF THE FORECAST IS IN GOOD SHAPE.

&&

.AVIATION...ISSUED 750 PM EDT FRI APR 15 2011

EASTERLY WINDS WILL CONTINUE TO GUST NEAR 30 KNOTS THIS EVENING
BEFORE EASING SLIGHTLY OVERNIGHT. PLAN TO MAINTAIN A MENTION OF
LOW LEVEL WIND SHEAR WITH THE MIXED LAYER DEPTH RIGHT AROUND 2000
FEET, BASED ON EARLY 00Z SOUNDING RETURNS, AND GIVE THE LOW LEVEL
JET AXIS A CHANCE TO MOVE TO OUR EAST SHORTLY AFTER MIDNIGHT.

WHILE THE WIND SPEED WILL EASE DURING THE NIGHT, PROBLEMS FOR
AVIATION WILL THEN BE REPLACED BY RAIN AND EVENTUALLY FOG AND LOW
CEILING. LOW PRESSURE MOVING FROM WESTERN ILLINOIS TO ABOUT CENTRAL
LAKE MICHIGAN WILL PULL A WARM FRONT THROUGH THE REGION THAT WILL
SUPPORT IFR CONDITIONS UNTIL ABOUT EARLY SATURDAY AFTERNOON. SOME
CEILING AND VISIBILITY IMPROVEMENT IS EXPECTED IN THE WARM SECTOR
OF THE SYSTEM THROUGH LATE AFTERNOON BUT ACCOMPANIED BY GUSTY
SOUTHWEST WINDS.

&&

.PREV DISCUSSION...ISSUED 400 PM EDT FRI APR 15 2011

SHORT TERM...TODAY THROUGH TOMORROW...

A 996MB SFC LOW IS CURRENTLY TREKING OVER WESTERN MISSOURI AND WILL
DEEPEN TO AROUND 985MB OVER THE NEXT 24 HRS. WITH THE HELP OF A
1036MB ARCTIC HIGH TO OUR NORTH...THE RESULTANT SURFACE PRESSURE
GRADIENT WILL HELP DRIVE GUSTY EASTERLY WINDS THROUGH THE EARLY
MORNING HOURS TOMORROW IN SPITE OF STRONG LL WARM ADVECTION THAT
WILL KEEP THE MIXING LAYER CAPPED AND MOMENTUM TRANSFER SOMEWHAT
LIMITED. ATTM...IT DOES NOT APPEAR THAT WIND ADVISORY CRITERIA WILL
BE MET. 00/12Z MODEL SUITE APPEARS TO BE REPRESENTING THE SYSTEM
WELL AS THE LOW LIFTS TO THE NORTHEAST AND A NARROW BAND OF WARM
FRONTAL PRECIP STRETCHING FROM CHICAGO THROUGH INDIANAPOLIS LIFTS
NORTH TOWARD OUR AREA. MODEL PROGS INDICATE THAT A BAND OF H7
FRONTOGENESIS WILL LIFT FROM S TO N ACROSS THE AREA BETWEEN ROUGHLY
3Z-8Z TONIGHT. AT THE SAME TIME WEAK TO MODERATE DIVERGENCE
ASSOCIATED WITH A 120KT JET STREAK AND Q-VEC FORCING FOR ASCENT WILL
OVERSPREAD THE AREA. IN THE LOW LEVELS...50-70KT SOUTHERLY FLOW WILL
TRANSPORT GULF MOISTURE NORTHWARD RESULTING IN PROGGED PWATTS
EXCEEDING ONE INCH. AS NOTED BY THE OVERNIGHT SHIFT...ISENTROPIC
ASCENT ALONG THE 300K SFC LOOKS TO BE QUITE STRONG...PARTICULARLY IN
THE 3Z-8Z TIME FRAME MENTIONED ABOVE...DURING WHICH MOST AREAS WILL
LIKELY SEE THEIR HEAVIEST RAINFALL. OVERALL..RELATIVELY LITTLE
CHANGE WAS NEEDED TO THE SHORT TERM AS THE PREVIOUS FORECAST HAS
CAPTURED THIS SYSTEM AND ITS EVOLUTION QUITE WELL.

LONG TERM...SATURDAY NIGHT THROUGH FRIDAY

THE STRONG LOW PRESSURE SYSTEM WILL CONTINUE TO DEEPEN SATURDAY
NIGHT INTO SUNDAY AS IT LIFTS THROUGH THE CENTRAL GREAT LAKES INTO
EASTERN ONTARIO. WHILE WRAPAROUND MOISTURE ON WEST FLOW AROUND THE
BASE OF THIS LOW WILL PROVIDE A CONTINUED CHANCE OF SHOWERS...EVEN
SNOW SHOWERS AS COLDER AIR FILTERS INTO THE AREA...THE MAIN STORY
WITH THIS STORM WILL BECOME THE WIND. WINDS WILL BEGIN TO GUST TO 30
MPH OR MORE SATURDAY NIGHT...AND THEN INCREASE FURTHER INTO SUNDAY
AS THE LOW REACHES ITS PEAK INTENSITY BY MIDDAY AND BETTER MIXING
LEADS TO ENHANCED WIND POTENTIAL WITHIN TIGHT PRESSURE GRADIENT THAT
WILL BE DRAPED ACROSS THE AREA IN THE WAKE OF THIS LOW. EXPECT WIND
GUSTS OF 40 MPH TO BE COMMON. DEPENDING ON THE EXACT POSITION OF THE
LOW BY THAT TIME...A WIND ADVISORY MAY VERY WELL BE REQUIRED. THE
TEMPERATURES WILL BE COOL...WITH HIGHS RANGE FROM THE MID 40S ACROSS
THE NORTHERN TIER OF THE CWA FROM THE SAGINAW VALLEY INTO THE THUMB
REGION TO THE LOWER 50S CLOSER TO THE OHIO STATE LINE. THE COLDER
AIR WITH THIS SYSTEM WILL REMAIN JUST OFF TO THE NORTH GIVEN THE LOW
PRESSURE POSITIONING BY SUNDAY.

WINDS WILL EASE QUICKLY SUNDAY NIGHT AS THIS SYSTEM LIFTS INTO THE
CANADIAN MARITIMES AND THE PRESSURE GRADIENT RELAXES BETWEEN THIS
SYSTEM AND A WARM FRONT THAT WILL BEGIN TAKING SHAPE WELL TO THE
SOUTH AS THE NEXT LOW PRESSURE SYSTEM BEGINS TO ORGANIZE OVER THE
CENTRAL PLAINS. A CHANCE OF RAIN SHOWERS WILL CONTINUE ACROSS THE
SOUTHERN CWA AS MOISTURE BEGINS TO OVERRUN THIS FRONT AS SHORTWAVE
ENERGY RIPPLES EAST THROUGH THE UPPER ZONAL FLOW LEFT BEGIN IN THE
WAKE OF THE WEEKEND SYSTEM. WITH THE WARM FRONT TO THE SOUTH...THE
TEMPERATURES WILL REMAIN SEASONABLY COOL WITH LOWS IN THE 30S TO
AROUND 40 SUNDAY NIGHT AND HIGHS INTO THE UPPER 40S TO LOWER 50S.
THE COOLEST READINGS WILL BE FOUND THROUGH THE SAGINAW VALLEY AND
THUMB WHERE EAST/NORTHEAST FLOW OFF OF THE COLD WATERS OF LAKE HURON
WILL HOLD TEMPERATURES IN THE LOWER/MID 40S NEAR THE SHORELINE.

MODELS ADVERTISE THE CONTINUATION OF THIS ACTIVE 7 TO 10 DAY
PERIOD...WHICH WILL INCLUDE THE NEXT SYSTEM FOR THE MIDDLE OF NEXT
WEEK...MONDAY NIGHT THROUGH WEDNESDAY.  LIKE THE ECMWF POSITION OF
THE WARM FRONT MON NIGHT INTO TUESDAY.  GFS...ESPECIALLY 12Z...MOVES
THE FRONT THROUGH MOST OF SE LOWER ON THE DAY TUESDAY WHILE THE MAIN
SURFACE LOW IS STILL DEVELOP WELL TO THE SW.  THAT WOULD NOT BE A
GOOD SETUP TO GET A WARM FRONT THROUGH SRN LWR MI EARLY IN THE
SPRING WITH OUR COLD GREAT LAKES.  AS THAT STORM MOVES TO THE NW OF
THE FORECAST AREA TUESDAY NIGHT AND WEDNESDAY...THEN THE WARM FRONT
SHOULD MOVE THROUGH MUCH OF SE MI.

MARINE...CURRENT OBSERVATIONS SUPPORT GALE OR NEAR GALE FORCE WINDS
ALREADY OCCURRING OVER NORTHERN LAKE HURON AS WELL AS A LAND-BASED
OBSERVATION SUGGESTING GALES OVER THE MICHIGAN WATERS OF LAKE ERIE.
IN ADDITION...OBS OF WIND GUSTS OVER LAKE MICHIGAN INCREASE
CONFIDENCE THAT GALE FORCE WIND FIELD HAS HEALTHY SPATIAL
CONTINUITY. THUS...GALE WARNING IS NOW IN EFFECT FOR ALL ZONES. WAVE
RESPONSE WILL BE IMPRESSIVE AS WELL WITH HEIGHTS AROUND 8-10 FT AND
12-14 FEET OVER NORTHERN LAKE HURON. AFTER A LULL ON SATURDAY
EVENING...STRONG WINDS WILL RESUME BEHIND THE COLD FRONT WITH COLD
ADVECTION LEADING TO HEALTHIER MIXING/MOMENTUM TRANSFER AND A
RENEWAL OF GALES OVER NORTHERN AREAS.
