AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
420 PM EDT WED JUN 21 2006

.SHORT TERM...TONIGHT AND THURSDAY

THE FIRST DAY OF SUMMER STARTED WITH THUNDER AND WILL LIKELY END
WITH THUNDER. THE MORNING ACTIVITY AND ASSOCIATED COLD POOL HAS
SUCCESSFULLY MANAGED TO SUPPRESS WARM FRONT TO THE WEST AND
SOUTHWEST...SO FAR. THE LATEST OBS ARE SHOWING SIGNS OF ATMOSPHERIC
RECOVERY AS TEMPS EDGE UPWARDS...AND WINDS AT THE SURFACE BEGIN TO
SLOWLY VEER FROM THE SOUTHEAST...THIS NOW BEING ACCOMPLISHED AS
LEFTOVER LOW LEVEL CLOUDS BEGIN TO THIN AND WARMER/MOISTER AIR JUST
TO OUR WEST AND SOUTHWEST CONTINUE IN OUR DIRECTION UNDER A STRONG
DEEP LAYER SOUTHWESTERLY FLOW. EXPECTATIONS CONTINUE FOR TEMPS AND
DEWPOINTS TO RISE CONSIDERABLY BETWEEN 430 PM AND 530 PM. THIS WILL
SUFFICIENTLY DESTABILIZE OUR ATMOSPHERE. A MODIFICATION OF THE 18Z
DTX SOUNDING TO 80/70...WHICH WE SHOULD EASILY ACHIEVE AS THE WARM
AIR FILTERS IN...YIELDS AROUND 3000 J/KG OF CAPE. THE MOISTURE IS
ALREADY IN PLACE AND WILL CONTINUE TO INCREASE AS THETA E ADVECTION
CONTINUES WITHIN THE STRONG SOUTHWESTERLY FLOW. THE 18Z SOUNDING
INDICATES A CAP LOCATED JUST ABOVE 750MB...BUT WILL LIKELY NOT BE
STRONG ENOUGH TO HOLD BACK SURFACE BASED CONVECTION WITHIN THE WARM
SECTOR EARLY THIS EVENING. THE LIFT WILL COME IN THE FORM OF
DYNAMICAL SUPPORT FROM A SHORTWAVE ADVANCING RAPIDLY EASTWARD AND
APPROACHING THE WESTERN GREAT LAKES AT THIS TIME. THE FAVORABLE
UPPER JET SUPPORT THAT WILL CROSS OUR AREA...COMBINED WITH THE
EXPECTED INSTABILITY IN PLACE BY THAT TIME WILL LEAD THE LIKELIHOOD
OF STRONG STORMS AS WE HEAD INTO THE EARLY EVENING HOURS.

SPC ANALYZED MLCAPE ACROSS NORTHERN ILLINOIS/NORTHERN INDIANA ARE
IN EXCESS OF 3000 J/KG AS OF 4PM AND THIS IS THE AREA WHERE WE ARE
EXPECTING ADDITIONAL SURFACE BASED CONVECTION TO BECOME BETTER
ORGANIZED AND THEN RIDE UP INTO OUR CWA BY EARLY EVENING. BULK SHEAR
IS VERY FAVORABLE FOR SUPERCELLS AND ORGANIZED SEVERE CONVECTION
THIS EVENING WITH STRONG WINDS THROUGH THE LAYER (18Z SOUNDING
SHOWED 55KT WINDS AT 10K FEET. WE CONTINUE TO REMAIN IN A MODERATE
RISK. THE PRIMARY RISK REMAINS DAMAGING WINDS BUT LARGE HAIL AND
ISOLATED TORNADOES...GIVEN THE FAVORABLE LOW LEVEL HELICITY
VALUES...CANNOT BE RULED OUT.

ANOTHER CONCERN FOR THIS EVENING WILL BE THE POTENTIAL FOR FLASH
FLOODING. THE GREATEST RAINFALL THIS MORNING OCCURRED ACROSS THE
SAGINAW VALLEY WHERE 2 TO 3 INCHES OF RAIN WAS REPORTED. WITH PWS
IN EXCESS OF 1.5 INCHES THIS EVENING...RAINFALL RATES THIS EVENING
WILL NEED TO BE CLOSELY MONITORED.

THE SHORTWAVE WILL QUICKLY EXIT TO OUR EAST BY MIDNIGHT. THE CONCERN
THEN TURNS TO THE POTENTIAL FOR FOG DEVELOPMENT. AT THIS TIME WE
WILL GO WITHOUT FOG IN THE ZONES UNTIL WE SEE HOW OUR ATMOSPHERE
RESPONDS AFTER THIS EVENINGS ACTIVITY.

ON THURSDAY WE TRANSITION TO A PREDOMINATE WESTERLY FLOW. A WEAK
COLD FRONT WILL APPROACH FROM THE NORTH LATE IN THE DAY.
TEMPERATURES ARE EXPECTED TO CLIMB INTO THE UPPER 80S UNDER PARTLY
CLOUDY SKIES AHEAD OF THE FRONT. THIS WILL HELP US TO REALIZE LOW
LEVEL LAPSE RATES (10C/KM) WHICH WILL REQUIRE US TO CONTINUE THE
MENTION OF THUNDERSTORMS THROUGH THE DAY. COOLER LOW LEVEL DEWPOINTS
AND A WEAK 850MB CAP LENDS ENOUGH CONFIDENCE TO CONTINUE WITH LOW
POPS.

&&

.LONG TERM...THURSDAY NIGHT THROUGH WEDNESDAY

GFS/NAM IN REASONABLE AGREEMENT THROUGH SATURDAY...HOWEVER THE GFS
IS A LITTLE QUICKER IN MOVING COLD FRONT SOUTH INTO THE OHIO VALLEY
THURSDAY EVENING. PREFER THE FASTER AND MORE AGGRESSIVE GFS COLD
FRONT SOLUTION AS THE NAM INITIALIZATION WAS 4 MB TO DEEP WITH
ASSOCIATED SURFACE LOW OVER NORTHERN ONTARIO. TREND IS FOR ZONAL
FLOW TO SLOWLY BUCKLE OVER THE GREAT LAKES REGION WITH NORTHWEST
FLOW HELPING TO DRIVE COLD FRONT SOUTH INTO THE OHIO VALLEY THURSDAY
THROUGH SATURDAY. WILL CONTINUE WITH A MENTION OF JUST SCATTERED
RAIN SHOWERS ACROSS THE SOUTHERN TWO TIER OF COUNTIES THURSDAY
NIGHT...AS MODELS SHOWING GOOD NEGATIVE MID LEVEL THETA-E ADVECTION
AND MID LEVEL DRYING...PUNCHING SOUTH ACROSS THE CWA. NAM IS A
LITTLE MORE SLUGGISH WITH COLD FRONT AND ALLOWS A COUPLE OF WEAK
WAVES RIDING THROUGH THE LOWER OHIO VALLEY TO HOLD THE FRONT UP EVEN
MORE. WILL HAVE TO WATCH THIS FRONT CLOSELY THOUGH AS IT NEARS THE
SOUTHERN EDGE OF THE WESTERLIES OVER THE NORTHERN OHIO VALLEY BY
FRIDAY MORNING. IN ADDITION FRONT STILL SOMEWHAT PARALLEL TO MID
LEVEL FLOW...EVEN IN GFS SOLUTION.

HIGH PRESSURE AND DRY NORTHWEST FLOW ALOFT TO BUILD INTO THE REGION
FOR FRIDAY THROUGH SUNDAY...THEN ECMWF AND GFS DIG TROF UPPER TROF
AXIS THROUGH THE REGION ON MONDAY...AND A WEAKER SECONDARY TROF ON
TUESDAY. WEAK GRADIENT AND LACK OF SIGNIFICANT RETURN FLOW WILL
LIMIT INSTABILITY OVER THE REGION THOUGH...SO MINIMAL POPS WITH
MENTION OF TRW THROUGH THE PERIOD. SOUTHERN EDGE OF WESTERLIES TO
MIGRATE NORTH AGAIN ON WEDNESDAY IN WAKE OF UPPER TROF AXIS...SO
CONTINUED CHANCE OF TRW ON WEDNESDAY AS WELL.

&&

AVIATION...ISSUED 213 PM EDT WED JUN 21 2006

A BREAK IN THE ACTION HAS BROUGHT ALL TERMINALS BACK UP TO VFR
CONDITIONS...ALBEIT TEMPORARILY. THE BEST TIMING FOR THE NEXT
ROUND OF THUNDERSTORMS LOOKS TO BE AROUND THE 6 PM TO 10 PM WINDOW
THIS EVENING. THIS WILL PRESENT MVFR CONDITIONS WITH PERIODS OF
IFR CONDITIONS IN THE STRONGEST THUNDERSTORMS. HAIL...GUSTY
WINDS...AND VERY HEAVY RAIN WILL ACCOMPANY THE STRONGEST THUNDERSTORMS
THAT OCCUR DURING THIS TIMEFRAME. THIS WILL BE FOLLOWED BY THE
DEVELOPMENT OF EITHER AN IFR LOW STRATUS DECK OR EITHER FOG WITH
IFR VISIBILITIES THAT WILL PERSIST THROUGH THE EARLY MORNING
HOURS.

THE 18Z SPECIAL DTX SOUNDING INDICATED A VERY WEAK LOW LEVEL
INVERSION WITH AN ABUNDANCE OF LOW LEVEL MOISTURE BENEATH. THIS
HAS RESULTED IN A POCKET OF MVFR CEILINGS FROM PONTIAC DOWN
THROUGH DETROIT...THUS THE BRIEF PERIOD OF MENTION IN THE DETROIT
TAFS TO START THE AFTERNOON OFF. MUCH WARMER AND MOISTER AIR IS
ADVECTING IN FROM OUR WEST AND SOUTHWEST...AND THE BEST TIMING FOR
THE WARM FRONT THROUGH OUR AREA IS AROUND 4 PM. THE ATMOSPHERE
WILL BECOME MUCH MORE UNSTABLE WITH GOOD BULK WIND SHEAR IN PLACE
TO SUPPORT THE LIKELIHOOD OF STRONG THUNDERSTORMS THIS EVENING.

BEYOND MIDNIGHT...A STRONG AND VERY LOW INVERSION WILL DEVELOP.
THIS WILL PROVIDE THE OPPORTUNITY FOR 2 CONCERNS. THE FIRST
CONCERN WILL BE THE DEVELOPMENT OF IFR CONDITIONS AS MOISTURE GETS
LOCKED IN CLOSE TO THE SURFACE. THE CHALLENGE IS WHETHER IT WILL
LAY OUT INTO A STRATUS DECK OR WHETHER FOG DEVELOPS. AT THIS TIME
WE WILL GO WITH A MIX OF THE TWO...AND PLACE MORE FOCUS ON THE FOG
POTENTIAL THAN THE LOW STRATUS CEILINGS. THE OTHER CONCERN IS LOW
LEVEL WIND SHEAR. STRONG LOW LEVEL WINDS JUST ABOVE THE INVERSION
AT AROUND 600 FEET WILL POSSIBLY RESULT IN LOW LEVEL WINDSHEAR...BUT
WE WILL WAIT UNTIL WE SEE JUST HOW THE ATMOSPHERE RESPONDS AFTER
THIS EVENINGS CONVECTION BEFORE INTRODUCING THIS INTO THE TAFS.
