AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
101 AM EDT MON AUG 1 2011

.AVIATION...

//DISCUSSION...

A WEAK SURFACE PRESSURE TROUGH WILL CONTINUE TO SETTLE SOUTH ACROSS
SOUTHEAST MICHIGAN OVERNIGHT.  AN ISOLATED SHOWER OR STORM REMAINS
POSSIBLE TONIGHT ACROSS ALL OF SOUTHEAST MICHIGAN AND EVEN INTO THE
DAY MONDAY AT THE DETROIT TERMINALS.  OTHERWISE...CLOUDS BELOW 12KFT
WILL BE RATHER SCARCE AND WINDS WILL REMAIN LIGHT.

//DTW THRESHOLD THREATS...

* LOW CONFIDENCE FOR AN ISOLATED SHOWER OR THUNDERSTORM AFTER 4 AM
TONIGHT AND AGAIN MONDAY.

&&

.PREV DISCUSSION...ISSUED 838 PM EDT SUN JUL 31 2011

UPDATE...

SCATTERED CONVECTION OVER WISCONSIN...LAKE MICHIGAN...AND NOW FAR
WESTERN LOWER MICHIGAN INITIATED ALONG A NEAR SURFACE CONVERGENCE
ZONE IN A REGION OF RESPECTABLE MIXED LAYER INSTABILITY. ELEVATED
LEVELS OF BOUNDARY LAYER MOISTURE HAVE POOLED ON THE LEEWARD SIDE
OF THE CONVERGENCE ZONE AND NUMERICAL GUIDANCE SUPPORTS
MAINTAINING AND ADVECTING APPRECIABLE / ~1500 J/KG / SLIGHTLY
ELEVATED /925-850MB LAYER BASED/ CONVECTIVE POTENTIAL TONIGHT
ACROSS LOWER MICHIGAN. LOCAL HIRES SOLUTIONS ALSO SUPPORT
INCREASING FLOW AROUND 925MB...SIGNIFYING THE ESTABLISHMENT OF A
MODEST INVERSION WIND MAX. THERE WILL BE A SLIGHT INCREASE IN
CONVERGENCE AT THE BASE OF THE REMNANT DIURNAL BOUNDARY LAYER
ALONG WITH SOME FURTHER DESTABILIZATION VIA NOCTURNAL COOLING AT
THE TOP OF THE MOISTURE RIBBON. THESE FACTORS SHOULD ESTABLISH
FAVORABLE CONDITIONS FOR ADDITIONAL WIDELY SCATTERED ILL-ORGANIZED
CONVECTION TO DEVELOP OVER WESTERN LOWER MICHIGAN AND CONTINUE TO
PERCOLATE THROUGH THE NIGHT ACROSS THE REST OF THE SOUTHERN LOWER
MICHIGAN.

PREV DISCUSSION...ISSUED 323 PM EDT SUN JUL 31 2011

SHORT TERM...TONIGHT

ANOTHER HOT...BUT DRY DAY (THROUGH 3PM) AS TEMPERATURES HAVE OR WILL
TOP OUT IN THE LOWER 90S/AROUND 90 DEGREES WITH LIGHT WESTERLY FLOW
AND MOSTLY SUNNY SKIES. SURFACE DEW POINTS REMAIN STUCK IN THE 60S
(OUTSIDE OF THE NORTHERN THUMB REGION)...WITH MIXED LAYER CAPES
BELOW 2000 J/KG...AS OF 18Z. A SURFACE TROUGH ARRIVING THIS EVENING
MAY BE ABLE TO TRIGGER ISOLATED TO LOW SCATTERED ACTIVITY...BUT LOSS
OF DIURNAL HEATING WILL WORK AGAINST THE TROUGH AS THE NIGHT WEARS
ON...WITH THE 850-700 MB THETA-E RIDGE AXIS MOVING THROUGH SOUTHEAST
MICHIGAN REMAINING FAIRLY DIFFUSE. CERTAINLY WORTHY OF SLIGHT/LOW
CHANCE POPS NONE-THE-LESS WITH THE MODEST HEIGHT FALLS/MID LEVEL
COOLING COMING IN. WITH THE FAVORABLE LATE DAY/EARLY EVENING TIMING
ACROSS THE NORTH THIRD OF THE CWA...MODERATE INSTABILITY AND
ADEQUATE 0-6 KM BULK SHEAR/DOWNDRAFT CAPE...AN ISOLATED SEVERE
THREAT WILL EXIST.

DID NOT SEE MUCH OF A NEED TO ADJUST INHERITED MINS...WHICH ARE IN
LINE WITH LATEST GUIDANCE.

LONG TERM...MONDAY INTO NEXT WEEKEND

SOUTHERN EXTENSION OF THE MID LEVEL HEIGHT FALLS ASSOCIATED WITH A
MID TROPOSPHERIC PV ANOMALY CURRENTLY SEEN PIVOTING ACROSS HUDSON
BAY WILL SETTLE INTO THE GREAT LAKES OVER THE NEXT 24 HOURS.  THIS
WILL EFFECTIVELY EASE A WEAK COLD FRONT SOUTHWARD AND THROUGH
SOUTHEAST MICHIGAN ON MONDAY.  THE DEGREE OF FRONTAL CONVERGENCE
WILL BE ON THE WEAKER SIDE.  HOWEVER...THE BACKGROUND THERMODYNAMIC
ENVIRONMENT WILL BECOME INCREASINGLY FAVORABLE FOR CELL GROWTH
SHOULD CONVECTION MANAGE TO INITIATE ALONG THIS BOUNDARY BEFORE IT
SHIFTS SOUTH OF THE AREA...AS A LOWERING HEIGHT FIELD ESTABLISHES
MUCH STEEPER LAPSE RATES WITH COOLING COMMENCING IN THE MID LEVELS.
MODEL SOUNDING DATA CONTINUE TO SUGGEST MLCAPE VALUES NEAR 2000
J/KG...ESPECIALLY SOUTH OF THE I-69 CORRIDOR. THIS SUPPORTS A LOW
END POP THROUGH THE DAY. ANY STORM THAT DEVELOPS WOULD CARRY A
RISK OF STRONGER WIND GUSTS WITH AN INCREASING DCAPE
PROFILE/INVERTED-V STRUCTURE AND JUST ENOUGH DEEP LAYER SHEAR TO
SUSTAIN AN ORGANIZED UPDRAFT. A WELL MIXED WESTERLY FLOW WITH 850
MB TEMPERATURES HOLDING IN THE UPPER TEENS WILL ALLOW HIGHS TO
AGAIN MAKE A RUN TOWARD 90/LOWER 90S OUTSIDE OF THE THUMB.

ANY POST-FRONTAL COOLING/DRYING WILL BE BRIEF AND RATHER MINOR INTO
MONDAY NIGHT...WITH DEVELOPING LOW LEVEL SOUTHWEST FLOW ALLOWING A
WARM FRONT AND INITIAL THETA-E GRADIENT TO SHIFT BACK THROUGH THE
REGION ON TUESDAY.  WHILE THE UPWARD VERTICAL MOTION ALONG THIS
FRONTAL ZONE WILL NOT BE OVERLY STRONG...THE AIRMASS ADJUSTMENT
ARRIVING IN CONJUNCTION WITH INCREASING DAYTIME DESTABILIZATION MAY
PROMOTE SCATTERED CONVECTIVE DEVELOPMENT THROUGHOUT THE DAY.  IN
ADDITION...A NOCTURNALLY DRIVEN CONVECTIVE COMPLEX WILL LIKELY
ORGANIZE MONDAY NIGHT OVER THE UPPER MS VALLEY AT THE INFLECTION
POINT OF STRONG LOW LEVEL JET DYNAMICS...MOISTURE ADVECTION AND
INCREASING MID LEVEL ASCENT WITH THE PASSAGE OF A STRONGER
SHORTWAVE.  THIS COMPLEX WILL HAVE BOTH THE THERMODYNAMIC/KINEMATIC
SUPPORT AND MEAN TRAJECTORY FOR POSSIBLE UPSCALE GROWTH INTO THE
GREAT LAKES ON TUESDAY...ARRIVING INTO SOUTHEAST MICHIGAN LATE
TUESDAY INTO TUESDAY NIGHT.  THUNDERSTORMS DEVELOPING BOTH IN
ADVANCE OF AND CONTAINED WITHIN ANY COMPLEX WILL CONTAIN A SEVERE
WIND/HAIL THREAT WITH 0-6 KM BULK SHEAR CLIMBING OVER 30 KNOTS AND
AT LEAST MODERATE INSTABILITY IN PLACE.  ASSUMING EARLY DAY
CLOUDS/PRECIPITATION ARE LESS PREVALENT...HIGHS WILL AGAIN PUSH
TOWARD THE 88 TO 92F RANGE.

DEEPER MOISTURE/INSTABILITY AXIS WILL SWEEP EAST BY WEDNESDAY
MORNING AS A COLD FRONT EXITS THE REGION.  LINGERING BOUNDARY LAYER
MOISTURE WILL PROMOTE A GENEROUS DIURNAL CU FIELD AND PERHAPS A
COUPLE OF SHOWERS UNDER WEAKLY CYCLONIC FLOW...WITH THE THERMAL
ADVECTIVE PROCESS NUDGING HIGHS DOWN A NOTCH INTO THE LOW-MID 80S.
LITTLE AIRMASS CHANGE NOTED FOR THURSDAY AS BUILDING HIGH PRESSURE
PROVIDES A HIGHER DEGREE OF DIABATIC HEATING.

SOUTHEAST MICHIGAN WILL REMAIN POSITIONED ON THE NORTHERN PERIPHERY
OF THE WEST TO EAST ELONGATED UPPER RIDGE FRIDAY INTO THE UPCOMING
WEEKEND.  THIS WILL LEAVE THE REGION ON THE EDGE OF THE CAP AND THE
MORE DEFINED INSTABILITY GRADIENT.  ILL-DEFINED SHORTWAVE
ENERGY...PERHAPS CONVECTIVELY ENHANCED...WILL ATTEMPT TO SLIDE
EASTWARD ALONG THIS AXIS AND WILL PROVIDE AT LEAST A LOW END
OPPORTUNITY FRIDAY. AIRMASS WILL UNDERGO SLIGHT MODERATION AS
UPPER HEIGHTS/THICKNESSES EASE UPWARD...BUT GENERALLY LOOKING AT
READINGS JUST A TICK ABOVE EARLY AUGUST NORMS /HIGHS MIDDLE-UPPER
80S...LOWS LOWER-MIDDLE 60S/.

CLIMATE...

WE WILL BE FINISHING JULY THE WAY WE STARTED...HOT. SO HOT IN
FACT...JULY 2011 WILL GO DOWN AS THE WARMEST ON RECORD AT
DETROIT...AS THE MONTHLY AVERAGE TEMPERATURE WILL LIKELY CHECK IN AT
79.3 DEGREES...BEATING THE 79.0 DEGREES SET IN 1955 AND 1921.
20 DAYS THE HIGH TEMPERATURE REACHED OR SURPASSED 89 DEGREES...TIED
FOR THE HIGHEST TOTAL (1955).

ASSUMING NO RAIN ARRIVES BEFORE MIDNIGHT...DETROIT WILL ALSO FINISH
AS THE SECOND WETTEST JULY ON RECORD WITH A TOTAL OF 7.66 INCHES.
THE RECORD IS 8.76 INCHES SET IN 1878.

MARINE...

THE NEXT SEVERAL DAYS WILL FEATURE LIGHT WINDS AND SMALL WAVES. THE
ONLY POSSIBLE DISRUPTION TO THE FAVORABLE BOATING CONDITIONS WILL
BE THE POSSIBILITY OF THUNDERSTORMS TONIGHT AND ESPECIALLY ON
TUESDAY AS LOW PRESSURE SYSTEM TRACKS THROUGH THE CENTRAL GREAT
LAKES REGION.
