//DISCUSSION...

REDUCED VISIBILITIES DUE TO HAZE AT TAF ISSUANCE SHOULD QUICKLY BURN
OFF/MIX OUT AS WINDS INCREASE TO 4-8 KNOTS AFTER SUNRISE. THE LIGHT
SOUTHWESTERLY FLOW WILL PERSIST THROUGH TONIGHT IN ADVANCE OF A SLOW
MOVING FRONT PUSHING SOUTH OUT OF CANADA. DRY CONDITIONS AND MOSTLY
SUNNY SKIES ARE EXPECTED UNTIL AT LEAST 06Z WITH JUST A SLIGHT
CHANCE OF A SHOWER OR THUNDERSTORM TOWARDS THE END OF THE TAF CYCLE
AS THE FRONT APPROACHES. CONFIDENCE IS NOT HIGH ENOUGH IN THIS
OCCURRENCE TO INCLUDE ANY MENTION OF PRECIPITATION IN THE FORECAST.
ALTHOUGH LIGHT WINDS SHOULD SUPPORT SOME MIXING OVERNIGHT...THERE
WILL BE A CHANCE OF HAZE/BR AGAIN AS LOW LEVEL MOISTURE/DEWPOINTS
CONTINUE TO INCREASE.

//DTW THRESHOLD THREATS...

.PREV DISCUSSION...ISSUED 412 AM EDT SUN JUL 17 2011

SHORT TERM...TODAY AND TONIGHT

TEMPERATURES AND HUMIDITY WILL CONTINUE TO CLIMB TODAY AS HEIGHTS
BUILD OVER THE REGION. SOUTHWESTERLY RETURN FLOW INCREASES AS THE
LOW PRESSURE SYSTEM OVER ONTARIO SLOWLY SINKS SOUTHWARD...ADVECTING
THE HOT AIRMASS THAT HAS BEEN PLAGUING THE PLAINS INTO NORTHERN
MICHIGAN. DEWPOINTS WILL CLIMB A FEW MORE DEGREES TODAY...AND THE
NAM IS ACTUALLY DOING PRETTY WELL SHOWING VALUES ONLY REACHING THE
MID AND UPPER 60S...WHILE THE TRULY MUGGY AIR LOCATED WEST OF LAKE
MICHIGAN WILL NOT ARRIVE UNTIL LATE TONIGHT AND MONDAY. HIGHS TODAY
WILL TOP OUT 2-4 DEGREES MORE THAN YESTERDAY IN THE 90-94 RANGE
WITH HEAT INDICES MAXING OUT AROUND 96...JUST SHY OF WHAT WE NEED
FOR A HEAT ADVISORY. THE DEPARTMENT OF ENVIRONMENTAL QUALITY HAS
ALSO ISSUED AN AIR QUALITY ALERT FOR COUNTIES ALONG AND SOUTH OF THE
M-59 CORRIDOR.

SHORTWAVE ENERGY MOVING AROUND THE UPPER LEVEL RIDGE FROM THE FOUR
CORNERS REGION HAS BEEN RESPONSIBLE FOR GENERATING CONVECTION IN
NORTH DAKOTA AND MINNESOTA OVERNIGHT. THESE THUNDERSTORMS HAVE SHOWN
SIGNS OF WEAKENING IN THE LAST COUPLE HOURS AS THEY TRACK EASTWARDS
INTO THE SURFACE RIDGE THAT STILL ENCOMPASSES THE ENTIRE GREAT LAKES
REGION. WITH NO LOW LEVEL JET IN THE VICINITY...EXPECT TO SEE THIS
DIMINISHING TREND CONTINUE INTO THIS MORNING HOURS. DAYTIME HEATING
AND ADDITIONAL SHORTWAVES ROUNDING THE RIDGE WILL LIKELY RESULT IN A
RE-INTENSIFICATION OF THIS ACTIVITY THROUGHOUT THE AFTERNOON. AT
THIS TIME IT IS EXPECTED TO BE TOO FAR REMOVED TO AFFECT SKY COVER
ACROSS SOUTHEAST MICHIGAN...BUT WILL BE SOMETHING TO MONITOR AS WE
HEAD INTO THE AFTERNOON. THE BULK OF THE MODELS SHOWS THE REMNANTS
OF THIS ACTIVITY CASCADING AROUND THE RIDGE TOWARDS LAKE HURON
OVERNIGHT...POSSIBLY IMPACTING NORTHERN PORTIONS OF THE CWA. ANOTHER
MCS WILL LIKELY DEVELOP ACROSS SOUTHERN WISCONSIN IN THE VICINITY OF
THE LOW LEVEL JET BUT IS EXPECTED TO REMAIN WEST OF THE FORECAST
AREA. GIVEN THE UNCERTAINTY IN HOW ALL OF THIS WILL PLAY OUT...HAVE
ADDED AT LEAST A SLIGHT CHANCE(20 POP) TO THE SOUTHERN HALF OF THE
FORECAST AREA WITH 30-40 POPS FURTHER NORTH. OTHERWISE...CONDITIONS
WILL BECOME INCREASINGLY HUMID OVERNIGHT AS DEWPOINTS CREEP UP TO
NEAR 70 DEGREES WITH THE LOW LEVEL THETA-E RIDGE OVERHEAD.

LONG TERM...MONDAY THROUGH SATURDAY

PRONOUNCED UPPER RIDGE AXIS WILL LIE TO THE WEST ON MONDAY...KEEPING
SOUTHEAST MICHIGAN ALONG THE NORTHEAST PERIPHERY AND WITHIN 40-50
KNOTS OF WEST-NORTHWEST MID LEVEL FLOW.  THIS SETUP PROVIDES A
FAVORABLE DOWNSTREAM POSITION FOR ANY FORWARD PROPAGATING/COLD POOL
DRIVEN MCS ACTIVITY EVOLVING UPSTREAM LATE TODAY/TONIGHT TO
POTENTIALLY IMPACT THE REGION ON MONDAY.  THIS ACTIVITY MAY BE TIED
TO ONE OR MORE WEAK MID LEVEL FILAMENTS FUNNELING OVER THE RIDGE
PERIPHERY.  GIVEN THE SCALE...MODELS FAIL TO CAPTURE THESE DETAILS
WITH ANY DEGREE OF CERTAINTY.  THERMODYNAMIC BACKGROUND WILL
CERTAINLY SUPPORT CONVECTION SHOULD SOME FORM OF LARGER SCALE ASCENT
COME TO FRUITION.  AN EARLY DAY WEAKENING MCS AND A CORRESPONDING
THICKER MID CLOUD FIELD WOULD CUT INTO THE HEATING POTENTIAL...BUT
MAY ALSO PROVIDE A MORE DEFINED DIFFERENTIAL HEATING/CONVERGENCE
ZONE FOR CONVECTION TO ANCHOR ALONG LATER IN THE DAY.  A MODIFIED
SOUNDING ASSUMING LIMITED HEATING DISRUPTION YIELDS UPWARDS OF 3000
J/KG OF WEAKLY CAPPED SBCAPE DURING THE AFTERNOON PERIOD.  UNDER
MODEST BUT STILL SUFFICIENT MID LEVEL FLOW/SHEAR PARAMETERS AND AN
INVERTED-V SOUNDING...A CONDITIONAL DAMAGING WIND THREAT DOES
EXIST. THE HIGH TEMPERATURE FORECAST FOR MONDAY REMAINS SLIGHTLY
CONSERVATIVE GIVEN THE POSSIBLE ISSUES WITH CLOUDS/PRECIPITATION...
GENERALLY WITHIN THE 88-91F RANGE.

A WEAK SURFACE REFLECTION WILL EASE SOUTH OF THE REGION ON TUESDAY
AS HIGH PRESSURE BUILDS ACROSS SOUTHERN ONTARIO.  THIS WILL SHIFT
THE PRIMARY THETA-E/INSTABILITY GRADIENT BRIEFLY BACK TO THE
SOUTH AND WEST THROUGH TUESDAY NIGHT.  THIS LEAVES THE LOCAL AREA
WITH NO REAL DEFINED FORCING MECHANISM TO OVERCOME A CAPPED MID
LEVEL ENVIRONMENT.  UNLESS THIS CHANGES VIA THE PASSAGE OF A MID
LEVEL WAVE/DECAYING MCS...ANTICIPATE A MODIFIED SOUNDING YIELDING
2500-3000 J/KG OF MLCAPE WILL REMAIN UNTAPPED.  THIS SUPPORTS THE
GOING DRY FORECAST FOR THESE PERIODS.  12Z GFS AND NAM DO ALLOW FOR
SOME WIDELY SCATTERED LATE DAY ACTIVITY...BUT LOOK ERRONEOUS THANKS
TO SOME CORRUPTIVE 76-77F DEWPOINT CONTOURS IN THE RAW DATA FIELD.
850 MB TEMPERATURES CONTINUE TO HOVER IN THE MID TO UPPER TEENS AND
FULLY MIXED SHOULD YIELD HIGHS RANGING FROM LOWER 90S SOUTH AND WEST
OF I-75 TO MID 80S IN THE THUMB.

THE PRONOUNCED UPPER RIDGE EXTENDING THROUGHOUT A LARGE MAJORITY OF
THE CONUS WILL MAKE THE HEAT AND HUMIDITY THE MAIN STORY RIGHT
THROUGH NEXT WEEKEND.  A WELL-MIXED AND DEEPENING SOUTHWEST FLOW
WILL AID THE ELEVATED HEIGHTS IN NUDGING DAYTIME TEMPERATURES UP A
NOTCH WEDNESDAY AND THURSDAY.  THURSDAY LOOKS TO BE THE WARMEST DAY
WITH THE LEAST AMOUNT OF UNCERTAINTY /POSSIBLE CLOUD AND
PRECIPITATION ISSUES/...WITH READINGS SOLIDLY ACHIEVING MID 90S PER
LATEST PROGGED THERMAL FIELDS.  ECMWF IS THE MOST AGGRESSIVE WITH
THIS HEAT...DRIVING AN IMPRESSIVE 26C 850MB TEMPERATURE AXIS INTO
THE REGION DURING THE DAY.  MIDWEEK CONDITIONS MAY NECESSITATE HEAT
RELATED HEADLINES...ESPECIALLY GIVEN THE POTENTIAL FOR CONSECUTIVE/
MULTIPLE DAYS OF HEAT INDICES IN THE 95-100 RANGE.

THETA-E GRADIENT WILL RECOIL BACK NORTHEAST ON WEDNESDAY IN RESPONSE
TO THE INCREASING SOUTHWEST FLOW.  THIS AXIS MAY PROVIDE ENOUGH
ASCENT TO SUPPORT CONVECTIVE DEVELOPMENT WITH THE AID OF DAYTIME
DESTABILIZATION.  IN ADDITION...CANNOT RULE OUT THAT A NOCTURNAL MCS
UPSTREAM WILL ANCHOR ALONG THE EDGE OF THE CAP AND THEN DROP
SOUTHEAST INTO THE REGION DURING THIS TIME.  SIMILAR CONDITIONAL
OPPORTUNITY WILL EXIST FRIDAY/SATURDAY...BUT NOT ENOUGH SUPPORT YET
GIVEN THE MID LEVEL WARMTH TO WARRANT A DEFINED POP MENTION THROUGH
THIS PERIOD.

MARINE...

GOOD MARINE CONDITIONS CAN BE EXPECTED AGAIN TODAY AS THE CENTRAL
GREAT LAKES REMAIN BETWEEN HIGH PRESSURE NEAR THE EAST COAST AND A
SLOW MOVING FRONT PUSHING SOUTH OUT OF CANADA. THIS WEAK FRONT WILL
PROVIDE A FOCUS FOR SCATTERED SHOWERS AND THUNDERSTORMS TO MOVE
SOUTH ACROSS THE GREAT LAKES FROM TONIGHT THROUGH MONDAY NIGHT.
THERE IS THE POTENTIAL FOR SOME OF THE STORMS TO BE STRONG ON
MONDAY...ESPECIALLY FROM SOUTHERN LAKE HURON TO LAKE ERIE. HIGH
PRESSURE WILL RETURN BEHIND THIS FRONT BRINGING FAVORABLE MARINE
CONDITIONS AGAIN FOR TUESDAY.
