...A LATE WINTER STORM SYSTEM WILL IMPACT THE REGION...

.LOW PRESSURE OVER THE TENNESSEE VALLEY THIS MORNING WILL LIFT INTO 
SOUTHERN MI THIS AFTERNOON. THE SOUTHEASTERLY GRADIENT WILL INCREASE 
DRAMATICALLY AS THIS OCCURS DUE THE PRESENCE OF STRONG ARCTIC HIGH 
PRESSURE OVER SOUTHERN QUEBEC. COLD AIR WILL SUSTAIN AN UNSTABLE 
PROFILE OVER THE LAKES TODAY AND WILL RESULT IN STRONG WINDS 
DEVELOPING. THE STRONGEST WILL OCCUR OVER LAKE HURON WHERE GUSTS 
SHOULD REACH GALE FORCE TO THE NORTH OF STURGEON POINT. THE LOW WILL 
LIFT INTO LAKE HURON THIS EVENING...THEN PHASE WITH A SECONDARY LOW 
PRESSURE SYSTEM TRACKING ACROSS LAKE SUPERIOR. THIS WILL WEAKEN THE 
GRADIENT OVER LAKE HURON...LEADING TO A LULL IN THE WINDS DURING THE 
LATE EVENING HOURS. AS THE UPPER LOW LIFTS NORTH OF LAKE HURON LATE 
TONIGHT INTO TUESDAY VERY COLD AIR AND STRONG WINDS WILL OVERSPREAD 
THE REGION AGAIN...WITH THE STRONGEST WINDS EXPECTED ACROSS THE 
SOUTHERN HALF OF LAKE HURON. THIS WILL WARRANT A GALE WATCH SOUTH OF 
STURGEON POINT FOR TUESDAY.

...STRONG WINDS TO IMPACT THE REGION THROUGH TUESDAY...

.A PAIR OF LOW PRESSURE SYSTEMS TO OUR SOUTH AND WEST ADVANCING INTO 
THE GREAT LAKES HAS TIGHTENED THE PRESSURE GRADIENT ACROSS NORTHERN 
LAKE HURON AS IT RUNS UP AGAINST A STRONG AREA OF HIGH PRESSURE OVER 
QUEBEC. COLD AIR ALOFT WITH A FAVORABLE FETCH NORTH OF THE TROUGH

WINDS RELAX TEMPORARILY. THE NORTHERN SFC LOW TRACKING ACROSS LAKE 
SUPERIOR WILL SWEEP A COLD FRONT THROUGH THE GREAT LAKES TONIGHT 
WHICH WILL VEER THE WINDS TO THE WSW. STRONG CAA AND A TIGHT 
GRADIENT WILL ALLOW GUSTY WESTERLY WINDS TO DEVELOP OVERNIGHT AND 
THROUGH TUESDAY WITH GALES FORCE GUSTS LIKELY FOR THE SOUTH HALF OF 
LAKE HURON...LAKE ST CLAIR...AND LAKE ERIE. WINDS WILL VEER TO THE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
315 AM EDT SUN MAR 17 2013

.SHORT TERM...TODAY AND TONIGHT

UPPER LEVEL TROUGH SWINGING THROUGH THE NORTHERN GREAT LAKES THIS
MORNING...WITH EXCELLENT NORTHWEST CONFLUENT FLOW IN THE TROUGH'S
WAKE TODAY...ALLOWING STRONG HIGH (1028 MB) TO BUILD OVER THE
CENTRAL GREAT LAKES. THE PRONOUNCED ANTI-CYCLONIC FLOW AND LOW
INVERSION HEIGHTS ARE EXPECTED TO YIELD BREAKS IN THE STUBBORN LOW
CLOUDS. STILL WILL HAVE TO CONTEND WITH THE LIGHT NORTHERLY FLOW OFF
LAKE HURON...AND THE AIRMASS IS COLD (-11 TO -14 C AT 850 MB) FOR
MID MARCH STANDARDS...AND TOUGH TO NOT FACTOR IN A TOUCH OF CU
DEVELOPMENT IF WE DO IN FACT CLEAR OUT. NO CHANGES TO INHERITED
MAXES WHICH ARE IN LINE WITH A BLEND OF MET/MAV GUIDANCE.

AN AMPLIFIED UPPER LEVEL RIDGE WILL BE BUILDING OVERHEAD
TONIGHT...WITH THE SURFACE HIGH RETREATING TO THE EAST AT A GOOD
CLIP. NONE-THE-LESS...WITH THE DRY LOW LEVEL EASTERLY
FLOW...ANTICIPATING JUST AN INCREASE IN CLOUDS OVERNIGHT AS LOW
LEVEL CONDENSATION PRESSURE DEFICIENT REMAIN HIGH...AROUND 300 MB.
ALTHOUGH...THERE WILL BE A REAL IMPRESSIVE SURGE OF MOISTURE AROUND
12Z MONDAY...WITH 290 K ISENTROPIC ASCENT JUST SOUTH OF THE
BORDER...AND WILL CARRY A LOW CHANCE OF FROZEN PRECIPITATION NEAR
THE OHIO BORDER TOWARD 12Z MONDAY.

LOOKING AT A QUICK DIP IN TEMPS THIS EVENING BEFORE RETURN FLOW/LOW
LEVEL WARM ADVECTION KICKS IN...AND MADE NO CHANGES TO INHERITED
MINS WHICH LOOKED REASONABLE (UPPER TEENS THUMB REGION TO MID 20S
SOUTH).

&&

.LONG TERM...MONDAY THROUGH SATURDAY

THE MID LEVEL TROUGH NOW ROTATING ACROSS THE PACIFIC NORTHWEST IS
FORECAST TO AMPLIFY AS IT EMERGES IN THE LEE OF THE NORTHERN ROCKIES
AND INTO THE NORTHERN PLAINS BY MONDAY. THE WAVE WILL THEN TAKE ON A
NEGATIVE TILT AS IT ROTATES ACROSS MN AND THE NRN GREAT LAKES
MON/MON NIGHT. THE WATER VAPOR LOOP SHOWS A MID LEVEL SHORT WAVE
OVER THE COLORADO ROCKIES. THIS WAVE IS FORECAST TO TRACK ALONG THE
LOWER TROPOSPHERIC FRONTAL BOUNDARY DRAPED ACROSS THE OHIO VALLEY
TONIGHT...LIFTING INTO THE EASTERN GREAT LAKES BY MON MORNING. THE
00Z MODEL SUITE CONTINUE SHOW ENOUGH SEPARATION BETWEEN THIS SHORT
WAVE AND THE LARGER SCALE TROUGH TRAVERSING THE NRN PLAINS TO KEEP
THE BETTER LOW LEVEL FGEN/MOISTURE TRANSPORT SOUTH OF THE STATE
THROUGH MON MORNING.

THE BETTER DYNAMIC FORCING ACROSS SE MI WILL THUS BE TIED TO THE
LARGER SCALE WAVE ADVANCING IN FROM MN. WHILE LARGE SCALE SUPPORT
VIA MID LEVEL HEIGHT FALLS AND UPPER LEVEL DIVERGENT FLOW WILL BE
QUITE GOOD...ESPECIALLY MON AFTERNOON... THE DEEPER MOISTURE IS
EXPECTED TO SLIDE SOUTHEAST OF THE AREA ALONG THE OHIO VALLEY
BAROCLINIC ZONE. MOISTURE DEPTH MAY ALSO BECOME PROBLEMATIC AS A
SUBSTANTIAL MID LEVEL DRY PUNCH HAS BEEN FORECAST TO OVERTAKE SRN
LOWER MI BY MON EVENING FOR SEVERAL MODEL CYCLES. THUS TOTAL QPF IS
EXPECTED TO BE LIGHT /LESS THAN 0.15 INCH/. THE INITIAL DRY AND COLD
AIR OVER SE MI WILL LEAD TO GOOD WET BULB COOLING AND THUS THE
POTENTIAL FOR THE ONSET OF PRECIP TO BE IN THE FORM OF SNOW. MODEL
SOUNDINGS DO HOWEVER SHOW THE DEPTH OF WARM AIR GROWING IN THE
BOUNDARY LAYER DURING THE AFTERNOON /ESPECIALLY ACROSS THE EASTERN
HALF OF THE FORECAST AREA/ TO SUPPORT A CHANGE OVER TO RAIN. THE
LACK OF MID LEVEL MOISTURE MAY ALSO BE SUPPORTIVE OF SOME DRIZZLE AT
TIMES.

THE MID LEVEL WAVE IS FORECAST TO EVOLVE INTO A CLOSED UPPER LOW BY
TUESDAY. THE OCCLUDED FRONT WILL LIFT NORTHEAST OF THE FORECAST AREA
MON EVENING WITH A COLD FRONT EXPECTED TO PUSH INTO SE MI EARLY TUES
MORNING. 850MB TEMPS WILL DROP TO -12 TO -14C TUES MORNING.
STEEPENING LOW LEVEL LAPSE RATES WITHIN A STRENGTHENING W-SW
GRADIENT WILL LEAD TO SOME GUSTY WINDS THROUGH THE DAY TUES /LIKELY
TOPPING 30 MPH AT TIMES/. WHILE DAYTIME HIGHS SHOULD REBOUND INTO
THE 30S...THE WIND CHILL READINGS WILL LIKELY REMAIN STUCK IN THE
TEENS AND 20S.

THE UPPER LOW IS FORECAST TO SLOWLY MEANDER TOWARD NEW ENGLAND BY
THE END OF THE WEEK AS A STRONG BLOCKING PATTERN DEVELOPS OVER NORTH
AMERICA WITH HIGH AMPLITUDE RIDGING BUILDING INTO HUDSON BAY. THE
MEDIUM RANGE MODEL SUITE HAVE SHOWN SOME CONTINUITY IN DEPICTING THE
CIRCULATION AROUND THE UPPER LOW ADVECTING SOME OF THE POLAR AIR
OVER CENTRAL CANADA INTO THE GREAT LAKES REGION ON WEDNESDAY...
LEADING TO THE COLDEST DAY IN THE FORECAST PERIOD AS 850MB TEMPS ARE
FORECAST TO DROP TO -16 TO -18C. EVEN UNDER THE MARCH SUN
ANGLE...THIS DEGREE OF COLD AIR IS LIKELY TO CAUSE DAYTIME HIGHS TO
STRUGGLE TO REACH FREEZING. A GRADUAL MODERATION OF THE AIRMASS IS
THEN EXPECTED LATE IN THE WEEK AND INTO NEXT WEEKEND...ACTUALLY
AIDED BY SOME SLIGHT WARM AIR ADVECTION FROM THE NORTHEAST. THIS
WILL SUPPORT FORECAST HIGHS GETTING INTO THE 40S BY FRIDAY INTO NEXT
WEEKEND...WHICH IS AT LEAST CLOSER TO SEASONAL NORMS.

&&

.MARINE...

A BACK DOOR COLD FRONT IS MOVING THROUGH NORTHERN LAKE HURON THIS
MORNING...WITH WESTERLY WINDS OF 20 KNOTS GUSTING UP TO 30 KNOTS.
THE ASSOCIATED WAVE TRAIN WILL SINK SOUTH...GLANCING THE EXPOSED
NEARSHORE WATERS OF THE THUMB TODAY...AND SMALL CRAFT ADVISORIES
HAVE BEEN ISSUED FOR OUTER SAGINAW BAY AND NEARSHORE WATERS OF LAKE
HURON FROM PORT AUSTIN TO PORT SANILAC.

STRONG LOW PRESSURE LIFTING INTO THE WESTERN GREAT LAKES TOMORROW
WILL SUPPORT INCREASING SOUTHEAST WINDS LATER TONIGHT AND
MONDAY...WITH GUSTS IN THE 25 TO 30 KNOT RANGE OVER MUCH OF LAKE
HURON. AS THE LOW LIFTS INTO ONTARIO ON TUESDAY...WINDS WILL BECOME
STRONG OVER THE ENTIRE CENTRAL GREAT LAKES REGION...WESTERLY 25 TO
30 KNOTS...WITH POTENTIAL FOR GALE FORCE GUSTS. STILL A BIT TOO FAR
OUT IN TIME TO ISSUE A GALE WATCH HOWEVER.

.AVIATION...ISSUED 1246 AM EDT SUN MAR 17 2013

//DISCUSSION...

CEILING WILL LINGER OVER SE MICHIGAN DURING THE EARLY MORNING HOURS
BUT IT WILL BE LOW END VFR. THE LATEST OBSERVATIONAL DATA SUPPORTS
NO MORE THAN A PATCH OF MVFR CEILING AS A WEAK COLD FRONT/TROUGH
SETTLES THROUGH LOWER MICHIGAN BEFORE SUNRISE. THIS BOUNDARY WILL
PASS THROUGH PERHAPS WITH A SNOW FLURRY AND THEN SHIFT THE WIND
TOWARD THE NORTH AT ALL LOCATIONS FOR THE MORNING AFTER SUNRISE.
STRONG HIGH PRESSURE WILL THEN BUILD INTO THE REGION DURING THE REST
OF THE DAY AND SLIDE OVER SOUTHERN ONTARIO BY SUNDAY NIGHT. THIS
FEATURE WILL SCOUR OUT ENOUGH LOW LEVEL MOISTURE FOR NO MORE THAN
SCATTERED STRATOCU UNDER JUST SOME THIN HIGH CLOUDS. INCREASING
EASTERLY FLOW DURING SUNDAY NIGHT WILL MARK THE APPROACH OF THE NEXT
LOW PRESSURE SYSTEM WHICH IS NOT EXPECTED TO IMPACT AVIATION
CONDITIONS UNTIL AFTER SUNRISE MONDAY.
