AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
323 PM EDT FRI JUN 6 2008
.SHORT TERM...THIS AFTERNOON AND TONIGHT
SURFACE HEATING HAS ALLOWED TEMPERATURES TO WARM INTO THE LOW 90S
ACROSS SOUTHEAST MICHIGAN AND DEWPOINTS HAVE COME DOWN INTO THE MID
60S AS WE CONTINUE TO MIX DOWN DRIER AIR ALOFT. MODIFICATION OF THE
12Z DTX SOUNDING TO CURRENT T/TD AT DTW OF 92/65 YIELDS JUST OVER
2000 J/KG OF SB CAPE. SOME CONCERN DOES STILL REMAIN ABOUT REALIZING
THIS GIVEN THE WARMER MID-LEVELS ON THE 12Z DTX SOUNDINGS...HOWEVER
12Z NAM/GFS FORECAST SOUNDINGS DID ERODE THE CAP BY LATE AFTERNOON.
INITIAL AREA OF THUNDERSTORMS HAS MOVED INTO WESTERN MICHIGAN AHEAD
OF A SURFACE COLD FRONT. OTHER FORCING MECHANISMS COINCIDING
WITH THE FRONT DO NOT LOOK PARTICULARLY STRONG...WITH LOW LEVEL
JET AXIS NOSING INTO NORTHWEST LOWER...AND H500 SPEED MAX AND RIGHT
ENTRANCE REGION FORCING BRUSHING US TO OUR NORTHWEST.
HOWEVER...GIVEN HIGH CAPE AND STEEP LOW-LEVEL LAPSE RATES...THINK
THIS AREA OF STORMS WILL FILL IN AS IT CONTINUES TO MOVE ACROSS
MICHIGAN...WITH TIME OF ARRIVAL INTO OUR WESTERN COUNTIES AFTER 400
PM. THE MOST LIKELY THREAT FROM THESE STORMS WILL BE DAMAGING WIND
GUSTS...WITH A FEW TORNADOES ALSO POSSIBLE. AS FAR AS STORM
MODE...STRONG UNIDIRECTIONAL SOUTHWESTERLY WIND PROFILE IS MOST
FAVORABLE FOR MULTICELL LINES AND BOW ECHOES...WITH A FEW SUPERCELLS
POSSIBLE. LARGE HAIL WILL BE POSSIBLE WITH THE STRONGEST
STORMS...BUT FREEZING LEVELS ABOVE 16000 SHOULD HELP MITIGATE THIS
THREAT. TORNADO WATCH IS IN EFFECT FOR ALL OF SOUTHEAST MICHIGAN
UNTIL 10 PM.
ONE FEATURE TO KEEP AN EYE THIS EVENING AS STORMS ROLL THROUGH
WILL BE THE PRESENCE OF QUASI-STATIONARY LAKE BREEZE BOUNDARY THAT
CAME ONSHORE LATE THIS MORNING. RADAR INDICATES THIS BOUNDARY AT
19Z WAS SITUATED FROM EASTERN MONROE COUNTY NORTHEASTWARD INTO
SOUTHEAST SANILAC COUNTY. AS STORMS APPROACH THIS BOUNDARY...EXPECT
STORM RELATIVE HELICITY TO INCREASE AS SOUTHEASTERLY WIND
COMPONENT INCREASES SLIGHTLY.
ACTIVITY WILL END BEHIND THE PASSAGE OF THE WEAK COLD FRONT LATE
THIS EVENING...WITH SKIES EVENTUALLY BECOMING PARTLY CLOUDY
OVERNIGHT AFTER DEBRIS EXIT. LOOKING FOR ANOTHER MILD AND HUMID
NIGHT...WITH TEMPERATURES ONLY FALLING TO AROUND 70.
&&
.LONG TERM...
THE HOT AND STICKY CONDITIONS WILL LINGER THROUGH THE WEEKEND.
UPPER LEVEL RIDGE WILL REMAIN ANCHORED OVER THE SOUTHEAST CONUS
THROUGH THE WEEKEND...WITH THE CENTRAL GREAT LAKES ON THE NORTHWEST
PERIPHERY (RING OF FIRE)...MAKING FOR A TOUGH FORECAST WITH RESPECT
TO PRECIPITATION CHANCES...AS THE GULF MOISTURE LINGERS OVER THE
EASTERN HALF OF THE CONUS.
FAIRLY DRAMATIC SWING IN PW VALUES OVER THE NEXT 24 HOURS
AS WEAKENING COLD FRONT SWINGS THROUGH THIS EVENING. A RENEWED SURGE
OF MOISTURE TOMORROW...WITH PW VALUES RISING BACK UP TO NEAR 2
INCHES OFF THE MORNING MIN AROUND 1 INCH...SUPPORTING AT LEAST
SLIGHT CHANCE/LOW CHANCE POPS WITH THE BUILDING INSTABILITY THROUGH
THE DAY.
STRONG SOUTHWEST FLOW ON SUNDAY..WITH SOUTHEAST MICHIGAN ON THE EDGE
OF THE CAP. WITH 500 MB HEIGHTS BELOW 588 DAM AND GOOD INSTABILITY
ADVERTISED (MIXED LAYER CAPES OF 1000-2000 J/KG)...FEEL IT IS
PRUDENT TO PUT IN A SLIGHT/LOW CHANCE POPS...EVEN THOUGH THERE IS NO
WELL DEFINED TRIGGER AT THE PRESENT TIME AND MARGINAL CAP...ALTHOUGH
MODELS (GFS/NAM) DO SUGGEST THERE WILL BE SOME UPPER LEVEL
IMPULSE(S) COMING OUT OF THE SOUTHERN PLAINS...AFFECTING THE
SOUTHERN GREAT LAKES SATURDAY NIGHT/SUNDAY. THE 12Z UKMET IS THE
MOST PRONOUNCED WITH THE RIDGE ON SUNDAY...AND WOULD SUPPORT MORE
WIDESPREAD LOWER 90S WITH CAP HOLDING.
BETTER SYNOPTIC SUPPORT FOR THUNDERSTORMS EARLY NEXT WEEK WITH
SHORTWAVE TROUGH AXIS TRACKING THROUGH THE GREAT LAKES REGION...AS
UPPER LEVEL LOW OVER THE PACIFIC NORTHWEST GETS BOOTED OFF TO THE
EAST BY THE GULF OF ALASKA SYSTEM...ALLOWING RIDGING TO BUILD BACK
INTO THE REGION TOWARD THE END OF THE WORK WEEK. USED HPC GRIDS FOR
DAYS 5-7.
&&
.MARINE...
GUSTY SOUTHERLY WINDS WILL CONTINUE OVER THE NEARSHORE AREAS THROUGH
THE AFTERNOON AND EARLY EVENING...BEFORE A WEAK COLD FRONT MOVES
THROUGH AND WINDS GRADUALLY DECREASE OVERNIGHT. WIND GUSTS WILL BE
HIGHER NEAR THE SHORELINES. THUNDERSTORMS ARE EXPECTED TO DEVELOP
ACROSS ALL MARINE AREAS THIS EVENING AHEAD OF THE FRONT. THESE
THUNDERSTORMS MAY BE SEVERE...PRODUCING WIND GUSTS IN EXCESS OF 35
KNOTS...LARGE HAIL...AND POSSIBLY EVEN TORNADOES/WATERSPOUTS.
THE GRADIENT WILL RELAX SLIGHTLY ON SATURDAY...BUT STILL PROVIDE
GUSTS OF BETWEEN 15 AND 20 KNOTS. A WEAKENING COLD FRONT WILL
TRAVERSE THE REGION SATURDAY NIGHT...PROVIDING A CHANCE FOR
THUNDERSTORMS. THERE IS A SLIGHT CHANCE THESE THUNDERSTORMS MAY BE
SEVERE. SMALL CRAFT ADVISORIES MAY ALSO BE NEEDED FOR THE NEARSHORE
AREAS AS WINDS INCREASE AHEAD OF THIS FRONT.
&&
.PREV DISCUSSION...ISSUED 216 PM EDT FRI JUN 6 2008
AVIATION...
WARM PRE-FRONTAL AIRMASS IN PLACE OVER THE REGION WILL CONTINUE TO
SUPPORT SOUTHERLY WIND GUSTS BETWEEN 25 AND 30 KNOTS. COLD FRONT
WILL APPROACH FOR THIS EVENING...WITH THUNDERSTORMS EXPECTED TO
DEVELOP OVER SOUTHEAST MICHIGAN LATE THIS AFTERNOON AND EVENING.
THESE STORMS ARE EXPECTED TO AFFECT THE TERMINAL SITES BETWEEN 21Z
AND 01Z. AN ATTEMPT WAS MADE TO TRY TO PIN DOWN THE HIGHEST THREAT
PERIOD IN THE 18Z TAF PACKAGE. THUNDERSTORMS MAY BE SEVERE...WITH
THE MOST LIKELY IMAPCT ON THE TERMINAL SITES BEING DAMAGING WINDS WITH
GUSTS IN EXCESS OF 50 KNOTS.
