AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
351 PM EDT SAT JUN 2 2007

.SHORT TERM...REST OF TODAY AND TONIGHT

TWO DISTINCT AREAS OF CONVECTION HAVE DEVELOPED THIS AFTERNOON
ACROSS THE WESTERN GREAT LAKES.  THE FIRST AREA OF THUNDERSTORMS
CURRENTLY IN THE WESTERN CWA INITIATED ALONG A REMNANT OUTFLOW FROM
THE OVERNIGHT ACTIVITY.  THIS WAS THE FIRST TO CU AS LOW LEVEL
MOISTURE POOLED BEHIND IN THE MID TO UPPER 60S...ALTHOUGH DEWPOINTS
IN ADVANCE OF THE BOUNDARY WERE EVEN IN THE MID 60S WITH LITTLE IN
THE WAY OF MIXING.  THE ENVIRONMENT CURRENTLY ACROSS THE CWA IS
CHARACTERIZED WITH SB CAPES OF 2000 J/KG WITH NOTHING IN THE WAY OF
A CAP.  THUS...CONVECTIVE DEVELOPMENT HAS TAKEN PLACE ALONG ANY
ENHANCED SURFACE CONVERGENCE...OUTFLOWS AND LAKE BREEZE BOUNDARIES.
THE SECOND REGION OF FOCUSED CONVECTION IS CURRENTLY ALONG A LINE
FROM EASTERN WISCONSIN SOUTHWARD TO NORTHERN INDIANA. THIS HAS BEEN
FORCED BY DCVA FROM SHORTWAVE ENERGY TRACKING EASTWARD ACROSS
PORTIONS OF ILLINOIS AND WISCONSIN...CONTINUED MOVEMENT BRINGING
INTO LOWER MICHIGAN LATER THIS EVENING.  UP TO THIS
POINT...DEVELOPMENT IN WISCONSIN HAS BEEN THE MOST ORGANIZED...WITH
CELLS IN NORTHERN ILLINOIS AND SOUTHERN LAKE MICHIGAN MULTICELL IN
NATURE.  MODEL GUIDANCE CONTINUES TO SUGGEST 30 PLUS KNOTS OF 0-6KM
BULK SHEAR SLIDING SOUTHEASTWARD OVER WESTERN LOWER MICHIGAN LATER
THIS EVENING.

EXPECTING THE FIRST BATCH OF PULSE STORMS ALREADY IN ACTION TO
PERSIST THIS LATE AFTERNOON INTO THE EARLY EVENING HOURS. LOSS OF
DIURNAL HEATING SHOULD DOWNTREND ACTIVITY AS INSTABILITY WANES.  THE
SECOND AFOREMENTIONED AREA SHOULD SPIKE IN INTENSITY ONCE IT REACHES
WESTERN LOWER MICHIGAN LATER THIS AFTERNOON...SB CAPES OF 3000 J/KG
AND MU CAPES OF PLUS 1500 J/KG.  WITH RELATIVELY HIGH AVAILABLE
POTENTIAL ENERGY AND INCREASED SHEAR FOR STORM
ORGANIZATION...WEST...THIS ACTIVITY SHOULD MAKE IT INTO OUR CWA AFTER
PEAK HEATING. THE NORTHERN CWA...TRI CITIES...THUMB STANDS THE BEST
CHANCE TO SEE THE BULK OF THIS WITH LOW TO MID LEVEL FGEN/OMEGA AND
Q VECTOR CONVERGENCE PERSISTENT IN THAT DEPICTION.  A SLIGHT CHANCE
OF SEVERE THUNDERSTORMS EXISTS ACROSS THE CWA THROUGH THIS EVENING.
THE GREATEST THREAT OF THE STRONGEST THUNDERSTORMS WILL BE HEAVY
RAIN...HAIL TO 1 INCH...AND WIND GUSTS TO 60 MPH.

A LULL IN PRECIPITATION IS ANTICIPATED AFTER THE SECOND ROUND...AND
CARRY US THROUGH THE END OF THIS FORECAST PERIOD.  WITH CLOUDS AND
HIGH DEWPOINTS LOWS WILL BE SIMILAR TO YESTERDAY IN THE LOW TO MID
60S.

&&

.LONG TERM...SUNDAY THROUGH SATURDAY

UPPER BLOCKING PATTERN FINALLY BREAKS DOWN WITH UPPER THAT HAS BEEN
STUCK IN SOUTH DAKOTA TRACKING THROUGH THE AREA AND MERGING WITH THE
ENERGY LEFTOVER FROM THE FLORIDA TROPICAL SYSTEM TO FORM A RATHER
DEEP UPPER TROUGH OVER THE NORTHEAST CONUS BY EARLY NEXT WEEK. THIS
WILL BRING A SIGNIFICANT PATTERN CHANGE...REPLACING OUR SUMMER-LIKE
CONDITIONS WITH PROGRESSIVELY COOLER WEATHER FROM SUNDAY NIGHT INTO
TUESDAY OR SO. THEREAFTER...A GRADUAL REBOUND IN TEMPERATURES IS
EXPECTED AS THE UPPER TROUGH LIFTS INTO THE CANADIAN MARITIMES AND
UPPER RIDGING BEGINS TO EDGE BACK INTO THE CENTRAL GREAT LAKES.

THIS PATTERN TRANSITION WILL BRING ACTIVE WEATHER TO THE AREA ON
SUNDAY & SUNDAY NIGHT AS THE UPPER LOW (&D ASSOCIATED SURFACE LOW
AND COLD FRONT) TRACK THROUGH THE REGION. SEE NO REASON TO ADJUST
THE FORECAST MUCH AS CATEGORICAL PRECIPITATION CHANCES (80%) SEEMS
TO BE ON TARGET FOR SUNDAY...WITH A GOOD CHANCE OF PRECIPITATION
LINGERING INTO THE EVENING HOURS BEFORE HEADING EAST OVERNIGHT.
WOULD EXPECT SOME SEVERE POTENTIAL GIVEN THE STRENGTH/TIMING OF THE
SYSTEM AND WILL HAVE TO EVALUATE THAT AFTER 1ST PERIOD CONVECTION
HAS DISSIPATED LATER TONIGHT. CERTAINLY EXPECT SOME LOCATIONS TO
RECEIVE QUITE A BIT OF RAIN WITH THE THUNDERSTORMS ON SUNDAY.

WILL MAINTAIN THE COOL DOWN EARLY NEXT WEEK (WITH ONLY 60S TO AROUND
70EXPECTED FOR HIGHS ON TUESDAY/WEDNESDAY). THEREAFTER...A GRADUAL
REBOUND BACK INTO THE UPPER 70S/LOWER 80S IS EXPECTED WITH BUILDING
UPPER LEVEL HEIGHTS LATE NEXT WEEK. THIS RETURN OF WARMER WEATHER
WILL ALSO MEAN A RETURN OF SHOWERS/THUNDERSTORMS AFTER A REASONABLY
QUIET PERIOD EARLY IN THE WEEK (ONLY EXPECT SCATTERED SHOWERS AS JET
ENERGY FUNNELS INTO THE DEVELOPING UPPER TROUGH DURING THE MONDAY
AND TUESDAY TIMEFRAME).

&&

.MARINE...

WITH THE CONTINUED INCREASE IN LOW LEVEL MOISTURE...SOME AREAS OF
FOG MAY DEVELOP OVER THE COOL OPEN WATERS OF LAKE HURON...WHICH
COULD PERSIST INTO SUNDAY BEFORE A COLD FRONT BRINGS DRIER AIR TO
THE REGION. SCATTERED SHOWERS AND THUNDERSTORMS WILL INCREASE IN
COVERAGE TONIGHT INTO SUNDAY...WITH ANY THUNDERSTORMS THIS WEEKEND
WILL BE CAPABLE OF PRODUCING HEAVY DOWNPOURS. NORTHWEST WINDS WILL
INCREASE LATE MONDAY INTO EARLY TUESDAY BEHIND A SECONDARY COLD
FRONT...WITH INSTABILITY AND WAVES INCREASING BEHIND THIS FRONT.
ALTHOUGH THIS SURGE IS RELATIVELY BRIEF...SMALL CRAFT ADVISORY
CONDITIONS ARE NOT OUT OF THE QUESTION MONDAY NIGHT INTO TUESDAY
MORNING OR SO.

.PREV DISCUSSION...ISSUED 152 PM EDT SAT JUN 2 2007

AVIATION...

WIDESPREAD CUMULUS (CIGS 3-4 KFT) DEVELOPMENT HAS TAKEN PLACE WITH
HIGHER SURFACE DEWPOINTS AND A RAPID RISE IN SURFACE TEMPERATURES.
ADDITIONALLY...THUNDERSTORMS HAVE INITIATED THE PAST HOUR ACROSS
CENTRAL LOWER MICHIGAN. HAVE INCLUDED THIS AS A TEMPO GROUP FOR
THIS AFTERNOON WITH EXISTING CELLS MAKING IT INTO THE DETROIT
METRO AREA THE NEXT HOUR OR TWO. STILL EXPECTING SECONDARY
DEVELOPMENT LATER THIS EVENING ACROSS THE SOUTHWESTERN PORTION OF
LOWER MICHIGAN WHILE PROPAGATING EASTWARD...AND INCLUDED THIS WITH
A LITTLE MORE ROBUST WORDING. THE NORTHERN
TERMINALS...KMBS...KFNT...APPEAR TO RECEIVE THE BRUNT OF THIS
ACTIVITY ROUGHLY BETWEEN 00-06 UTC. ABUNDANT LOW LEVEL MOISTURE
WILL KEEP VISIBILITIES REDUCED INTO THE MVFR THRESHOLD THROUGH THE
MORNING. THUNDERSTORM DEVELOPMENT IS AGAIN EXPECTED TOMORROW AS
MAIN UPPER LEVEL ENERGY FINALLY ARRIVES IN SOUTHERN MICHIGAN.
