AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
652 PM EDT THU JUN 28 2012

.AVIATION...

//DISCUSSION...

A COLD FRONT EXTENDS FROM THE THUMB TO CENTRAL ILLINOIS. THIS
FRONT WILL PUSH ACROSS THE REST OF SE MI THROUGH THE REMAINDER OF
THE EVENING. DESPITE POOLING OF LOW LEVEL MOISTURE ALONG THIS
FRONT...THE ATMOSPHERE IS STRONGLY CAPPED WHICH HAS BEEN
EFFECTIVELY INHIBITING THUNDERSTORM DEVELOPMENT. THERE IS HOWEVER
A MID LEVEL SHORT WAVE NOW ADVANCING INTO SRN LAKE MI. LOCALIZED
MID LEVEL COOLING IN ADVANCE OF THIS WAVE HAS INITIATED SOME
CONVECTION OVER SOUTHERN LAKE MICHIGAN...WHICH WILL LIKELY
PROGRESS TO THE EAST-SOUTHEAST DURING THE COURSE OF THE EVENING
AND POSES THE RISK OF IMPACTING METRO DETROIT IN THE 02Z TO 05Z
TIME FRAME. DRIER AIR WILL THEN INFILTRATE THE REGION OVERNIGHT
INTO EARLY FRI MORNING.

//DTW THRESHOLD THREATS...

* LOW CONFIDENCE IN THE CHANCES OF THUNDERSTORMS THIS EVENING.

&&

.PREV DISCUSSION...ISSUED 404 PM EDT THU JUN 28 2012

SHORT TERM...THIS EVENING AND TONIGHT

LATEST SATELLITE/SURFACE OBSERVATIONS SHOW WEAK MID-TROPOSPHERIC
WAVE AND ATTENDANT SURFACE PRESSURE TROUGH APPROACHING SOUTHEAST
MICHIGAN. MOSTLY SUNNY SKIES PREVAIL THOUGH THANKS TO LARGE CAPPING
INVERSION AT THE BASE OF AN IMPRESSIVE ELEVATED MIXED LAYER.
MOISTURE POOLING ALONG AND BEHIND THE COLD FRONT WILL ALLOW PARCELS
AN ATTEMPT AT BREAKING THROUGH THE CAP THIS EVENING. BEST LOW LEVEL
THETA-E SURGE WILL SLIDE ACROSS THE SOUTHERN CWA DURING THE NEXT FEW
HOURS AS THE 750-800MB CAP WEAKENS. 12Z NAM/MET GUIDANCE HAS COME
INTO BETTER ALIGNMENT WITH REALITY IN REGARDS TO SURFACE DEWPOINTS
WITH VALUES SURGING INTO THE UPPER 60S OVER THE PAST FEW HOURS. THIS
HAS KEPT OUR TEMPS SLIGHTLY SUBDUED EVEN WITH FULL SUN OVER THE
AREA. NAM BUFR SOUNDINGS FOR DTW SUGGEST WE NEED A SURFACE PARCEL OF
ROUGHLY 98/70 TO GET PAST THE CAP. THOUGH NOT OUTSIDE THE REALM OF
POSSIBILITY...IT WILL BE DIFFICULT TO ACHIEVE SUCH A COMBINATION OF
HIGH HEAT AND MOISTURE. FORECAST SOUNDINGS ALSO SHOW ABOUT 50-75
J/KG OF MLCIN. THIS WILL BE DIFFICULT TO OVERCOME WITH THE OVERALL
WEAK BACKGROUND FORCING FOR LIFT. OF COURSE...IF ANY CONVECTION DOES
MANAGE TO GET PAST THE CAP IT WILL VERY LIKELY BE SEVERE WITH NEARLY
3000 J/KG OF MLCAPE AND 30+ KTS OF 0-6KM SHEAR. SEVERE WINDS WOULD
BE THE MAIN THREAT WITH 1500+ J/KG OF DCAPE ENCROACHING ON OUR
SOUTHERN CWA. LATEST HI-RES MODEL RUNS SUGGEST CONVECTION FIRING IN
THE EXTREME SOUTH AND EASTERN PARTS OF OUR AREA AROUND 00Z. THIS
SEEMS REASONABLE GIVEN THE BETTER LOW LEVEL THETA-E AND INSTABILITY
ACROSS THE SOUTH. CONFIDENCE IS NOT HIGH ENOUGH TO RAISE POPS THOUGH
AND WILL CONTINUE WITH LOW CHANCE FOR THE EVENING. OVERNIGHT LOWS
WILL NOT PROVIDE MUCH RELIEF FROM THE HEAT AS TEMPS ONLY DROP INTO
THE LOW TO MID 70S ACROSS METRO DETROIT. A FEW MODEL RUNS HINTED AT
AN MCS DEVELOPING OVER IOWA LATE TONIGHT BUT THIS FEATURE...IF IT
DEVELOPS...WILL REMAIN TOO FAR TO THE SOUTHWEST TO IMPACT OUR CWA
TONIGHT. THE ONLY POSSIBLE IMPACT WILL BE INCREASING HIGH CLOUDS BY
THE EARLY MORNING HOURS.

LONG TERM...FRIDAY THROUGH WEDNESDAY

LOW AMPLITUDE LONG WAVE PATTERN WILL CHANGE VERY LITTLE THROUGH THE
WEEKEND WITH PERSISTENT RIDGING LOCATED OVER THE CENTRAL CONUS. THE
GREAT LAKES REMAINS IN THE W/NW FLOW ON THE LEE SIDE OF THE RIDGE
AND ON THE EDGE OF THE AIRMASS PRODUCING THE RECORD SETTING TEMPS
OVER MUCH OF THE CENTRAL/SOUTHERN PLAINS. SEVERAL WEAK SHORT WAVES
ARE FORECAST TO PASS WITHIN THE FLOW MOSTLY NORTH OF THE STATE BUT
SOME WEAK COLD FRONTS...OR MORE SO WIND SHIFT BOUNDARIES OR DENSITY
GRADIENTS...SHOULD MAKE THEIR WAY THROUGH THE REGION. WITH HIGH
DEWPOINTS LOOMING JUST TO OUR SOUTH AND POSSIBLY WORKING INTO SE MI
AT TIMES AND SOME ELEVATED LIFT/INSTABILITY WITH THE PASSING
SYSTEMS...THERE WILL BE LOW CONFIDENCE POPS SCATTERED THROUGH THE
EXTENDED PERIOD. A WAVE TRAIN EMBEDDED WITHIN THE JET OVER THE
NORTHERN PACIFIC WILL CONTINUALLY FEED ENERGY INTO THE TROUGH
POSITIONED OVER THE WEST COAST. THIS ENERGY WILL EVENTUALLY DEEPEN
THE TROUGH AROUND MIDWEEK WHICH WILL THEN RE-AMPLIFY THE RIDGE OVER
THE PLAINS AND STALL ANY EASTWARD PROGRESS IT WAS TRYING TO
MAKE...POSSIBLY EVEN PULL IT SLIGHTLY WESTWARD. WHAT THIS MEANS IS
THE ABOVE AVERAGE HEAT WILL CONTINUE FOR SEVERAL MORE DAYS...WITH
HIGHS IN THE LOW TO MID 90S INTO THE WEEKEND BEFORE RETREATING INTO
THE UPPER 80S. WILL ALLOW THE CURRENT HEAT ADVISORY TO CONTINUE
THROUGH FRIDAY EVENING FOR TEMPS ONCE AGAIN REACHING INTO THE MID
90S AND TAKING INTO ACCOUNT THE COMPOUNDING FACTOR OF TODAY/S HEAT AS
WELL.

PRECIP CHANCES WILL BE ON THE LOW SIDE THROUGH THE NEXT WEEK WITH
THE STALLED FRONTAL BOUNDARY LINGERING TO OUR SOUTH AND WEAK FRONTAL
BOUNDARIES PASSING THROUGH THE REGION. FIRST CHANCE WILL BE ON
SATURDAY AFTERNOON/EVENING AS A STRONG WAVE PASSES THROUGH ONTARIO
WITH SOUTHERN EXTENT OF THE TROUGH PASSING THROUGH THE LAKES. THE
TROUGH WITH THE STALLED FRONT NEARBY WILL WARRANT CONTINUED MENTION
OF POPS...ALTHOUGH MOISTURE MAY BE A LIMITING FACTOR. THE NEXT
CHANCES WILL BE ON SUNDAY WITH A SECONDARY TROUGH DROPPING INTO THE
STATE AND AGAIN LATE TUESDAY INTO WEDNESDAY AS MODELS INDICATE A
SLIGHTLY STRONGER WAVE ENTERING THE REGION. BUT ONCE AGAIN...NONE OF
THESE FEATURES ARE TOO EYE OPENING AT THE MOMENT.

MARINE...

QUIET WEATHER CONTINUES FOR THE MARINE AREAS AS A RIDGE OF HIGH
PRESSURE BRINGS VERY WARM AIR TO THE REGION...CREATING STABLE
CONDITIONS OVER THE LAKES. A WEAK COLD FRONT WILL CROSS THE REGION
THIS EVENING BUT DRY AIR AND STABLE CONDITIONS WILL LIMIT THE
COVERAGE OF SHOWERS AND THUNDERSTORMS. LIGHT WINDS AND LOW WAVES
WILL THEN CONTINUE THROUGH THE WEEKEND.

FIRE WEATHER...

FIRE WEATHER CONCERNS WILL CONTINUE THROUGH TOMORROW AND SATURDAY AS
A VERY HOT AND DRY AIR MASS SETTLES ACROSS THE REGION. AFTERNOON RH
VALUES TODAY REMAINED ABOVE THE CRITICAL 25% MARK AS SURFACE DEW
POINTS CLIMBED INTO THE UPPER 60S. WIND GUSTS ALSO STAYED BELOW 25
MPH. EXPECT SIMILAR CONDITIONS TOMORROW WITH AFTERNOON RH VALUES
APPROACHING 25% AND WIND GUSTS APPROACHING 25 MPH AS A VERY DEEP
MIXED LAYER DEVELOPS. DEW POINTS WILL BE SLIGHTLY HIGHER ON SATURDAY
BUT AN INCREASING PRESSURE GRADIENT WILL ALSO BRING STRONGER WINDS.
A RED FLAG WARNING MAY BE NECESSARY FOR EITHER OR BOTH DAYS.

MICHIGAN.

.DAY ONE...TODAY AND TONIGHT

TEMPERATURES ARE EXPECTED TO RISE INTO THE MID AND UPPER 90S WITH HEAT
INDICES AROUND 100 DEGREES...SEE LATEST HEAT ADVISORY PRODUCT FOR MORE
DETAILS.

THE HEAT WILL ALSO CREATE ENOUGH INSTABILITY TO BRING A SLIGHT
CHANCE OF A FEW THUNDERSTORMS LATE THIS AFTERNOON OR EARLY THIS

HAIL UP TO ONE INCH IN DIAMETER AS THEY MOVE TO THE SOUTHEAST
AROUND 30 MPH.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

THERE IS A CHANCE OF THUNDERSTORMS FOR SATURDAY AND SUNDAY...MAINLY
DURING THE AFTERNOON HOURS. SUNDAY OFFERS THE BEST CHANCE OF
THUNDERSTORMS ACROSS SOUTHEAST MICHIGAN. A STATIONARY FRONT WILL
BE OVER OR CLOSE TO THE REGION THIS WEEKEND...BUT A WEAK AREA OF LOW
PRESSURE WILL MOVE ALONG THE FRONT ON SUNDAY TO GIVE A BETTER
CHANCE OF THUNDERSTORMS.

THERE WILL BE ANOTHER CHANCE OF THUNDERSTORMS NEXT WEDNESDAY...
INDEPENDENCE DAY.

THE COMBINATION OF MORE HEAT...DRY CONDITIONS AND INCREASING GUSTY
WINDS ON FRIDAY MAY LEAD TO DANGEROUS FIRE WEATHER CONDITIONS TO NEAR
