AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
345 PM EDT SUN JUL 15 2012

.SHORT TERM...TODAY AND TONIGHT

THE INFLECTION POINT/CENTER OF AN EMBEDDED VORTICITY MAXIMUM IS
CURRENTLY SCRAPING SOUTHWARD ALONG THE SHORELINE OF LAKE HURON NEAR
WHITE ROCK AND FORESTVILLE. SHOWER AND THUNDERSTORM ACTIVITY HAS BECOME
NUMEROUS TO THE SOUTH AND EAST OF THIS FEATURE WITHIN THE WARM AIR
ADVECTION QUADRANT. THERE IS A BIT OF EVIDENCE CONFIRMING THAT MIXED
LAYER CAPES HAVE REACHED UPWARDS OF 1500 J/KG WHICH IS FAIRLY
IMPRESSIVE FROM WHAT HAS BEEN SEEN RECENTLY. THIS RELATIVELY HIGH
AMOUNT OF CAPE HAS BEEN RESPONSIBLE FOR SOME .88 TO 1.0 INCH HAIL
REPORTS TAKEN FROM THE STRONGER CORES IN ST CLAIR COUNTY. WITH A
LACK OF COLUMN FLOW AND SHEAR...STORM ORGANIZATION WILL REMAIN AT
PULSE TYPE TO BRIEFLY MULTICELLULAR AT TIMES. THUS...THE RISKS WITH
THUNDERSTORMS THIS AFTERNOON WILL CONTINUE TO BE GUSTY WINDS TO 40
MPH AND HAIL OF UP TO 1.0 INCH. HEAVY DOWNPOURS WILL ALSO BE
POSSIBLE WITH ANY OF THE CELLS AS A FEW LOCATIONS TODAY HAVE ALREADY
SEEN A VERY QUICK 1.5 TO 2 INCHES OF RAIN.

A VORTICITY LOBE TO SOUTHWEST OF THE FORESTVILLE CENTER HAS BEEN
SUPPORTING SOME ADDITIONAL DEVELOPMENT OVER SAGINAW BAY AND PORTIONS
OF CENTRAL LOWER MICHIGAN NEAR ALMA. THIS AREA OF SHOWERS AND
THUNDERSTORMS IS ALIGNED WITHIN A MAXIMUM OF LOW TO MIDLEVEL THETA
E. THE MODELS SWEEP THIS HIGHER MOISTURE CONTENT TO THE SE ACROSS
THE CWA DURING THE 20-00Z TIMEFRAME. THUS...SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE THROUGH ROUGHLY 00Z. THE LOSS OF
INSOLATION SHOULD CAUSE ANY REMNANT ACTIVITY TO DISSIPATE RATHER
QUICKLY.

THE ELONGATED TROUGH AXIS ALOFT WILL PUSH EASTWARD LATE THIS EVENING
OPENING THE DOORS FOR GEOPOTENTIAL HEIGHT RISES OVERNIGHT. A SURFACE
RIDGE AXIS WILL ALSO BUILD ACROSS THE CWA. EXPECT CLEAR SKIES
OVERNIGHT...WITH CONDITIONS NOT NEARLY AS MUGGY AS TEMPERATURES ARE
EXPECTED TO FALL AREAWIDE INTO THE 60S.

&&

.LONG TERM...MONDAY THROUGH SUNDAY

MODELS CONTINUE TO SUPPORT UPPER RIDGING BUILDING INTO THE GREAT
LAKES. WILL CONTINUE TO LEAN TOWARD NAM AND ECMWF SOLUTIONS WITH THE
GFS ISSUES.  A SHORTWAVE OVER ND IS EXPECTED TO DIVE OVER LOWER MI
LATE ON MONDAY AND MONDAY EVENING WITH LITTLE FAN FAIR. JUST TOO DRY
IN ALL LEVELS OF THE ATMOSPHERE TO HAVE ANY POPS.  THEN LOOK FOR THE
SURFACE FRONT TO MOVE INTO THE NORTHERN PARTS OF THE FORECAST AREA
TUESDAY EVENING AND ACTUALLY BE SOUTH OF THE FORECAST AREA ON
WEDNESDAY. IT APPEARS THAT THE 925 TO 850 FRONT WILL BE MORE ACTIVE
WITH THIS SHALLOW FRONT...WHICH DOES NOT MAKE IT THROUGH THE
FORECAST AREA UNTIL WEDNESDAY AFTERNOON. NOT MUCH UPPER LEVEL
SUPPORT AS THE SHORTWAVES STAY NORTH OF THE GREAT LAKES.

WITH THE DRY AIR AND 850 MBS TEMPS WARMING TO AROUND 20 TO THE LOWER
20S...EXPECT MIXING TO REACH ABOVE 800 MBS AND POSSIBLY TO 750 MBS.
CURRENT FORECAST OF LOWER TO MID 90S LOOKS ON TARGET. DEW POINTS IN
THE UPPER 50S SHOULD KEEP HEAT INDICES IN CHECK FOR MONDAY.

COLD FRONT DROPS INTO THE NORTHERN PART OF THE FORECAST AREA ON
TUESDAY...BUT NOT BEFORE 850 TEMPS GET TO 23C. MOISTURE ALL LAGS
BEHIND THE FRONT ALONG THE 925 AND 850 FRONTS. WE SHOULD MIX WELL
ABOVE 800 MBS...PERHAPS AS HIGH AS 725 MBS...AND INTO THE ELEVATED
MIXED LAYER. WINDS WILL HAVE A STRONG WESTERLY COMPONENT AND AS HIGH
AS 10 TO 15 KNOTS AT THE SURFACE. THESE ALL SUGGEST KEEPING THE
CURRENT 96 TO 100 DEGREE FORECAST FOR TUESDAY...IF NOT A DEGREE
WARMER. DEW POINTS WILL CREEP INTO THE LOWER TO MID 60S WHICH WILL
CREATE HEAT INDICES ABOVE 100...AND TOWARD 105. HEAT ADVISORIES WILL
BE LIKELY...BUT DEFINITELY LESS THAN 50 PERCENT CONFIDENCE OF A HEAT
WARNING EVENT THAT WOULD NECESSITATE A WATCH.

MLCAPES GET UP TO 1500 J/KG ACROSS THE TRI CITIES AND THUMB REGION
WITH SOME GOOD CONVERGENCE IN THE BOUNDARY LAYER ALONG THE SHALLOW
FRONT. 500 MB WINDS INCREASE CLOSE TO 40KTS WITH SHEAR APPROACHING
30KTS. THERE IS ALSO SOME WEAK UPPER DIVERGENCE ASSOCIATED WITH THE
RIGHT REAR ENTRANCE REGION OF THE 70-80KT UPPER JET. WILL ADD A
CHANCE OF THUNDERSTORMS FOR THESE REGIONS LATE TUESDAY.

THESE FEATURES ALL SLIDE ACROSS SE LOWER MI ON TUESDAY
NIGHT...ALTHOUGH THE MLCAPES DECREASE DRAMATICALLY WITH THE LOSS OF
THE DIURNAL COMPONENT.  THE SCATTERED STORMS WILL BECOME TRULY
ELEVATED AS CAPES ARE STILL 1500 J/KG OR MORE LIFTING FROM 850 MBS.

PROBABLY ENOUGH CAPE AND SHEAR THAT AN ISOLATED SEVERE STORM IS
POSSIBLE TUESDAY AFTERNOON AND EVENING IN THE TRI CITIES AND THUMB
REGIONS...AND THEN ISOLATED SEVERE HAIL OVERNIGHT TUESDAY FOR THE
REST OF THE FORECAST AREA.

ON WEDNESDAY...SHALLOW FRONT WILL CONTINUE TO SLIP SOUTH. LOOKS LIKE
ENOUGH OF THE COOLER...DRIER AND STABLE AIR WILL SLIP INTO THE TRI
CITIES AND THUMB TO HAVE A DRY FORECAST ON WEDNESDAY...WITH MORNING
CHANCES NEAR FLINT AND WILL KEEP THE CHANCE ALL DAY FOR I-94 ON
SOUTH. WILL HAVE MORE OF A GRADIENT ACROSS THE FORECAST AREA ON
WEDNESDAY WITH THE FRONTAL POSITION. UPPER 70S TO AROUND 80 LOOKS ON
TARGET FOR THE TRI CITIES AND THUMB...BUT MIXING INTO SOME WARMER
TEMPS FOR DETROIT ON SOUTH COULD GET US A SNEAKY UPPER 80S DAY.

IN THE EXTENDED...MORE DRY CONDITIONS AS THE SURFACE HIGH PRESSURE
BUILDS INTO THE REGION. EXTENDED MODELS AND ENSEMBLES ALL HAVE CLOSE
TO THE SAME SYNOPTIC SOLUTIONS WITH OBVIOUS FINE DETAIL DIFFERENCES
THAT FAR OUT. THE TUESDAY NIGHT AND WEDNESDAY SYSTEM REINFORCES THE
NORTHERN QUEBEC UPPER LOW.  500 MB HEIGHTS LOWER JUST A BIT FOR
THURSDAY AND FRIDAY.  THEN HEIGHTS BUILD AGAIN ON SATURDAY AND
SUNDAY AHEAD OF THE NEXT WEAK WAVE. WILL CONTINUE THE TREND OF THE
LAST SEVERAL MONTHS...DRY AIR AND MOSTLY CLEAR SKIES LEADING TO
WARMER AIR AND WARMER THAN GUIDANCE TEMPS. EVEN BEHIND OUR FRONT ON
THURSDAY AND FRIDAY 850 TEMPS REACH 12C-16C WITH EXPECTED MIXING TO
AROUND TO 850 MBS WHICH SHOULD LEAD TO TEMPS A LITTLE WARMER THAN
CURRENT FORECAST. THEN 850 TEMPS WARM BACK TOWARD AROUND 20 TO THE
LOWER 20S FOR NEXT WEEKEND. WILL WARM THOSE TEMPS A LITTLE
TOO...SOLIDLY INTO THE 90S AGAIN.

&&

.MARINE...

A WEAK SURFACE PRESSURE GRADIENT WILL MAINTAIN QUIET MARINE
CONDITIONS THROUGH MONDAY MORNING WITH WINDS OF GENERALLY 10 KNOTS
OR LESS FOR NEARSHORE ZONES AND 10 TO 15 KNOTS OVER THE OPEN WATERS.
WAVES WILL BE 2 FEET OR LESS ACROSS AREA WATERS DURING THIS TIME.
BREEZY SOUTH WINDS OF 15 TO 20 KNOTS WILL THEN SPREAD ACROSS LAKE
HURON ON MONDAY AFTERNOON...GRADUALLY TURNING TOWARD THE WEST
SOUTHWEST ON MONDAY NIGHT AS A FRONT SHIFTS THROUGH THE AREA.
CONDITIONS MAY APPROACH SMALL CRAFT ADVISORY FOR SAGINAW BAY AND
AROUND THE THUMB ON MONDAY NIGHT AS THE SUSTAINED BREEZE MAY FORCE
WAVE HEIGHTS INTO THE 3 TO 5 FOOT RANGE AWAY FROM THE IMMEDIATE
SHORELINE. IMPROVING CONDITIONS ON TUESDAY WILL BE FOLLOWED BY MORE
TRANQUIL CONDITIONS FOR THE REST OF THE WEEK AS HIGH PRESSURE
SETTLES ACROSS THE GREAT LAKES. THERE IS A CHANCE FOR THUNDERSTORMS
TODAY AND AGAIN MONDAY NIGHT THROUGH EARLY WEDNESDAY.

&&

.AVIATION...ISSUED 230 PM EDT SUN JUL 15 2012

//DISCUSSION...

AN EMBEDDED SHORTWAVE/VORTICITY CENTER IS CURRENTLY OVER THE
SHORELINE OF LAKE HURON NEAR HARBOR BEACH. CONVECTIVE TEMPERATURES
WERE REACHED WITH HIGHER 60S DEWPOINTS TO THE SOUTH AND ALLOWED FOR
A LOCALIZED MASS CONVECT EPISODE PRIMARILY ACROSS THE FAR EASTERN
CWA...ST CLAIR AND MACOMB COUNTIES. THIS AREA HAPPENS TO RESIDE IN
THE SOUTHERLY WAA SECTOR OF THIS EMBEDDED SHORTWAVE. SATELLITE
IMAGERY SUGGESTS THE NEAR TERM SHOWER/TSTORMS ALONG THIS VORTICITY
FILAMENT WILL PUSH EASTWARD INTO ONTARIO/LAKE HURON DURING THE NEXT
HOUR. CONFIDENCE IS NOT AT ALL HIGH WITH WHAT WILL EVOLVE OUT OF THE
AGITATED CUMULUS LINE BUILDING BACK TO THE SOUTHWEST FROM JACKSON TO
GOSHEN. HIGH RESOLUTION MODELS SUGGESTS THAT AS THE SHORTWAVE LOBE
IN ASSOCIATION WITH THE HARBOR BEACH CENTER SETTLES SOUTHWARD DURING
THE AFTERNOON HOURS THE NEXT CHANCE FOR SHOWERS AND TSTORM WILL
OCCUR ALONG THIS FEATURE TRENDING FROM NORTH TO SOUTH BETWEEN
18-00Z. THIS HAS BEEN TIMED FOR THE TAF SITES WITH A TEMPO GROUP.
OTHERWISE...MIDLEVEL DRY AIR ADVECTION TONIGHT WILL BRING VFR TO SKC
SKIES.

AT KDTW...LEFT OUT THIS INITIAL ROUND OF SHOWERS AND TSTORMS AS THIS
EARLY ACTIVITY HAS BEEN FAVORING TO THE NORTHEAST AND WILL EXIT
MOMENTARILY. WILL WATCH TWO ADDITIONAL FEATURES FOR THUNDERSTORMS
DEVELOPMENT. THE FIRST IS WITH THE TRAILING LINE OF CUMULUS OVER
SOUTH CENTRAL LOWER MICHIGAN...WHILE THE SECOND IS WITH DEEPER
SHORTWAVE ENERGY NOW SINKING SOUTHWARD INTO THE SAGINAW BAY AREA.

//DTW THRESHOLD THREATS...

* LOW CONFIDENCE IN TIMING CEILING HEIGHTS ABOVE 5000 FEET DURING
THE AFTERNOON

* LOW CONFIDENCE IN TIMING OF THUNDERSTORM POTENTIAL FOR THE
AFTERNOON HOURS.
