AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
306 PM EDT THU JUN 21 2012

.SHORT TERM...TONIGHT

SHOWERS AND THUNDERSTORMS THAT HAVE FORMED ALONG/AHEAD OF THIS
AFTERNOON'S COLD FRONT WILL QUICKLY EXIT TO THE EAST THIS EVENING.
UNTIL THIS OCCURS, ISOLATED MARGINALLY SEVERE HAIL/WIND WILL REMAIN
POSSIBLE ACROSS THE EASTERN THIRD OF THE CWA. ELSEWHERE, TRAILING
SHOWER AND ISOLATED T-STORM ACTIVITY WILL DISSIPATE OVER THE CWA
COINCIDENT WITH THE LOSS OF DIURNAL HEATING THIS EVENING. LIGHT
WESTERLY WINDS BEHIND THE FRONT WILL THEN CONTINUE TO BRING COOLER
AND DRIER AIR INTO THE FORECAST THROUGH THE NIGHT, PROMOTING COOL
OVERNIGHT LOW TEMPERATURES FALLING TO AROUND 60 DEGREES UNDER
CLEARING SKIES.

&&

.LONG TERM...

NORTHWEST FLOW WILL DOMINATE THE EXTENDED PERIOD...ALLOWING FOR
TEMPERATURES NEAR NORMAL OVER THE NEXT SEVERAL DAYS...AS EXPANDING
UPPER LEVEL RIDGE DEVELOPS ALONG THE FOOTHILLS OF THE ROCKIES.

TIMING OF THE UPPER LEVEL DISTURBANCES WITHIN THE JET CORE WILL BE
DIFFICULT...AND THESE ISSUES BEGIN TO SHOW UP FOR THE WEEKEND.

LARGE UPPER LEVEL LOW OVER EASTERN CANADA PROGGED TO DESCEND
SOUTHWARD...WITH EXACT CENTER OF THE COLD POOL IN QUESTION FOR EARLY
NEXT WEEK...AS INTERACTION WITH TROPICAL DISTURBANCE IN THE GULF OF
MEXICO IS UP ON THE AIR AS WELL (SEE 00Z CANADIAN VS EUROPEAN
SOLUTION).

COMPACT UPPER LEVEL WAVE OVER SOUTH CENTRAL CANADA WILL SWING
THROUGH NORTHERN LOWER MICHIGAN LATE TOMORROW...AND CERTAINLY LOOKS
SUFFICIENT TO GENERATE A FEW SHOWERS AND THUNDERSTORMS WITH THE
IDEAL TIMING OF THE DAY...AND RAPIDLY FALLING 500 MB TEMPS (-4 C
CHANGE DURING THE DAY). ILL DEFINED SFC-850 MB WIND/PATTERN/LOW
LEVEL CONVERGENCE WILL LIMIT ORGANIZATION AND COVERAGE. MET GUIDANCE
LOOKS GOOD...AROUND 80/LOWER 80S.

LARGE AREA OF HIGH PRESSURE (1018 MB) SETTLES OVER THE GREAT LAKES
REGION ON SATURDAY...AND DESPITE AN UPPER LEVEL DISTURBANCE TRACKING
THROUGH LATER IN THE DAY....WILL MAINTAIN DRY FORECAST AS LOW LEVEL
STATIC STABILITY WILL BE HIGH. WITH AN INCREASE IN MID/HIGH CLOUDS
DURING THE AFTERNOON...MAXES CAPPED AROUND 80 DEGREES SEEMS
REASONABLE.

THE FORECAST THEN BECOMES LESS CERTAIN FOR THE SECOND HALF OF THE
WEEKEND...AS FORMIDABLE SHORTWAVE TROUGH SWINGS INTO THE NORTHERN
GREAT LAKES. WARM ADVECTION OUT AHEAD OF THIS SYSTEM COULD MAKE
SUNDAY A SNEAKY WARM DAY...AS 12Z UKMET SHOWING 850 MB TEMPS
SURGING TO 17 C BY 12Z SUNDAY. HOWEVER...SURFACE FRONT LOOKS TO BE
HUNG UP (ALONG/NORTH OF I-69)...WITH SHOWERS AND THUNDERSTORMS
POSSIBLE...WHICH WOULD LIMIT THE MAXES (SUB 80 DEGREES). WILL PLAY
THE MIDDLE GROUND...UPPER 70S/NEAR 80 NORTH...80S SOUTH.

STILL LOOKING FOR COOL DOWN NEXT WEEK AS LARGE UPPER LEVEL LOW LOOKS
TO BE SETTLING OVER THE EASTERN GREAT LAKES. WE LOOK TO BE ON THE
WESTERN FRINGE (ALTHOUGH 12Z EURO ARGUES FOR A MORE DIRECT
BLOW)...WHICH INCLUDES THE MOISTURE GRADIENT...SO DIURNAL SWINGS ARE
IN QUESTION...ALONG WITH SLIGHT CHANCE OF SHOWERS.
REGARDLESS...THINKING TEMPS WILL AVERAGE ABOUT 5 DEGREES BELOW
NORMAL.

&&

.MARINE...

WEST TO NORTHWEST FLOW WILL BUILD ACROSS AREA WATERS IN THE WAKE OF
THIS AFTERNOON'S FRONT, BUT WILL DO SO AT A SPEED LOW ENOUGH TO
MAINTAIN LOW HEIGHTS. HIGH PRESSURE WILL THEN BUILD IN THROUGH THE
FIRST HALF OF THE WEEKEND, PROVIDING CONTINUED LIGHT WINDS AND WAVES
WITH JUST SLIGHT CHANCE OF A THUNDERSTORM ON FRIDAY AFTERNOON.  THE
PATTERN WILL THEN BECOME MORE ACTIVE BEGINNING ON SUNDAY AS COOLER
AIR SURGES INTO THE AREA BRINGING WITH IT RENEWED THUNDERSTORM
CHANCES.

.AVIATION...ISSUED 1207 PM EDT THU JUN 21 2012

//DISCUSSION...

UPSTREAM SURFACE AND SATELLITE OBSERVATIONS SHOW A COLD FRONT
MARCHING TOWARD SOUTHEAST MICHIGAN FROM THE WEST EARLY THIS
AFTERNOON. CONDITIONS AHEAD OF THE FRONT WILL CONTINUE TO BE
CHARACTERIZED BY A GUSTY SOUTHWEST WIND AND MOSTLY CLEAR / VFR
CONDITIONS UNTIL THE UPSTREAM CLOUD SHIELD WORKS ACROSS THE AREA
BETWEEN 18Z AND 00Z.  DURING IT'S PASSAGE, WHICH WILL OCCUR IN THE
WAKE OF THE SURFACE COLD FRONT / WIND SHIFT, CEILINGS WILL FALL
BELOW 5000 FEET BUT ONLY AN OCCASIONAL MVFR CEILING POSSIBLE BASED
ON CURRENT OBSERVATIONS OVER WESTERN LOWER MICHIGAN. THE EXCEPTION
WILL BE WITHIN ANY HEAVIER SHOWER OR THUNDERSTORM ACTIVITY, WHICH
IS FORECAST TO GRADUALLY INCREASE IN COVERAGE THROUGH THE PEAK
HEATING HOURS - ESPECIALLY TOWARD THE DETROIT METRO AREA, INCLUDING
THE KPTK TO KDTW CORRIDOR. WINDS WILL TURN TO THE WEST BEHIND THE
FRONT, USHERING IN MOSTLY CLEAR CONDITIONS AFTER THE PASSAGE OF THE
NARROW PLUME OF DEEPER MOISTURE AND ASSOCIATED BAND OF CLOUDS. AFTER
SEVERAL HOURS OF CLEAR CONDITIONS, PATCHY STRATOCU IN THE 4-5KFT
RANGE MAY FILTER IN TOWARD SUNRISE.

FOR DTW...THE MOST FAVORABLE TIME WINDOW FOR THUNDERSTORMS TO AFFECT
DTW AIRSPACE IS BETWEEN 19Z AND 22Z AS THE COLD FRONT PUSHES
THROUGH THE METRO AREA. THE UNCERTAINTY REGARDING THE COVERAGE OF
THUNDERSTORMS HAS NOT CHANGED, BUT IT IS POSSIBLE THAT STRONG
THUNDERSTORMS COULD DEVELOP OVERHEAD OR PERHAPS JUST EAST OF THE
AIRFIELD THIS AFTERNOON BEFORE QUICKLY EXITING TO THE EAST.

//DTW THRESHOLD THREATS...

* LOW CONFIDENCE THAT A THUNDERSTORM WILL IMPACT DTW

* HIGH CONFIDENCE ON CEILING BELOW 5000 FEET AFTER THE FRONTAL
PASSAGE.
