AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
358 PM EDT WED JUL 16 2008

.SHORT TERM...THIS AFTERNOON AND TONIGHT

A HEALTHY DOSE OF ANTICYCLONIC VORTICITY ADVECTION HAS PROVED
SUFFICIENT IN SUPPRESSING ANY REAL CONVECTIVE DEVELOPMENT THROUGH
THE EARLY AFTERNOON HOURS. WITH THE OVERALL WEAK COLUMN WIND
PROFILE...MULTIPLE BOUNDARIES/SOME INTERSECTING...HAVE DEVELOPED
ACROSS SOUTHEASTERN MICHIGAN. THE MAIN STATIONARY FRONT HAS CURRENT
PLACEMENT ALONG A LINE FROM NEW BALTIMORE TO LUDINGTON. IN
ADDITION...A NUMBER OF LAKE BOUNDARIES ARE SHOWING UP PARALLEL TO
THE LOCAL WATERWAYS. PLENTY OF INSTABILITY RESIDES SOUTH OF THE
STATIONARY FRONT WHERE AFTERNOON SBCAPES HAVE REACHED/EXCEEDED 3500
J/KG. THEREFORE...EXPECT THUNDERSTORM DEVELOPMENT 21Z-00Z ALONG AND
SOUTH OF THE DESCRIBED LARGER SCALE BAROCLINIC ZONE (FAVORING
ENHANCED SURFACE CONVERGENCE FROM LAKE BOUNDARIES).

TONIGHT...MODEL GUIDANCE ADVERTISES THE CVA ASSOCIATED WITH THE
WISCONSIN STORMS TO SPREAD INTO PORTIONS OF CENTRAL AND SOUTHEASTERN
LOWER MICHIGAN. HAVE MAINTAINED/BUT INCREASED THE CHANCE POPS 00-06Z
FOR THE NORTHERN CWA. CONCEPTUALIZING ADDITIONAL DEVELOPMENT
EASTWARD INTO LAKE MICHIGAN/WESTERN PORTIONS OF LOWER MICHIGAN.
WITH THE GREATER SYNOPTIC SUPPORT/CVA AND 850MB THETA E ADVECTION.
THIS IDEA IS FOSTERED AS OBSERVATIONAL/NUMERICAL GUIDANCE EVIDENCE
SUGGESTING THE INSTABILITY AXIS LYING FROM NORTHWEST TO SOUTHEAST
ALONG THE REFERENCED BAROCLINIC ZONE.

WITH RESPECT TO THE INSTABILITY...A SLIGHT CHANCE OF SEVERE STORMS
WILL EXIST FOR ALL LOCATIONS.  A BELT OF STRONGER WESTERLIES IN
PLACE NORTH OF THE FORECAST AREA IS OVERLAPPING AREAS NORTH OF I69
(0-6KM BULK SHEAR OF 30 KNOTS).  THEREFORE...EXPECT BEHAVIOR SOUTH
OF I 69 TO REMAIN PULSE TYPE WITH MULTICELLS POSSIBLE NORTH UNDER
GREATER SHEAR. THOUGHTS ARE UNCHANGED...HAIL TO ONE INCH AND
DAMAGING WIND GUSTS TO 60 MPH WILL BE THE MAIN THREATS THROUGH
MIDNIGHT. GIVEN SLOW STORM MOVEMENT...TORRENTIAL RAINFALL WILL ALSO
BE POSSIBLE.

LOWS TONIGHT WILL SETTLE INTO THE 60S FOR ALL AREAS...70 FOR THE
METRO AREA.

&&

.LONG TERM...THURSDAY THROUGH WEDNESDAY

THE EARLY PART OF THE EXTENDED FORECAST REMAINS CONSISTENT WITH THE
PREVIOUS FORECAST AS THE NORTHERN EDGE OF A LARGE UPPER HIGH OVER
THE SOUTHERN GREAT LAKES IS VERY GRADUALLY SHUNTED SOUTH AS A NUMBER
OF SHORTWAVES RACE ALONG THE WESTERLIES NEAR THE CANADIAN BORDER. A
SURFACE FRONT DRAPED NORTH OF THE CWA ON THURSDAY WILL SLOWLY EDGE
SOUTH BACK INTO THE AREA BY SATURDAY...BEFORE STALLING. WITHIN THIS
REGIME...WOULD EXPECT SHOWER/THUNDERSTORM ACTIVITY TO BE MINIMIZED
ON THURSDAY AND PRETTY MUCH INTO FRIDAY AS WELL. AREAS FROM M 59 ON
SOUTH LUCKY SEE MUCH MORE THAN AN ISOLATED/WIDELY SCATTERED SHOWERS
AND THUNDERSTORMS. WILL MAINTAIN A 20-30% CHANCE I 69 NORTH AS ANY
ACTIVITY FOCUSED ALONG THE FRONT TO THE NORTH WOULD HAVE A BETTER
CHANCE OF CLIPPING THE REGION DUE TO ANY PROPAGATION EFFECTS. AS THE
FRONT SAGS BACK INTO THE REGION ON SATURDAY...PRECIPITATION CHANCES
WILL INCREASE DUE TO BETTER CONVERGENCE AND MOISTURE POOLING. WILL
INCREASE THE CHANCE OF SHOWERS/THUNDERSTORMS TO 40% SATURDAY WITH
THIS GENERAL IDEA HOLDING INTO SUNDAY.

AT THIS POINT IN THE FORECAST...A MAJOR UPPER LEVEL PATTERN CHANCE
IS FORECAST AS THE ZONAL FLOW LATE THIS WEEKEND INTO THE WEEKEND
AMPLIFIES AS A LARGE SHORTWAVE DISTURBANCE...DROPPING SOUTH ALONG
THE BRITISH COLUMBIA COAST TODAY...MAKES ITS WAY INTO THE GREAT
LAKES BY MONDAY AND RESULTS IN A LARGE UPPER LOW WHICH THEN STALLS
OVER THE AREA FOR THE BALANCE OF THE FORECAST. PERIODIC SHOWERS AND
THUNDERSTORMS WILL PERSIST...BUT IN A LESS ORGANIZED FASHION AS THE
MAIN MECHANISM WILL BE DIURNAL INSTABILITY UNDER THE COLD POOL OF
THE UPPER LOW.

TEMPERATURES WILL START OUT VERY WARM ON THURSDAY/FRIDAY WITH HIGHS
INTO THE LOWER 90S IN MOST AREAS AS THE SURFACE FRONT WILL BE NORTH
OF THE AREA AND SOUTHWEST FLOW CONTINUES TO FEED HOT AIR INTO THE
CENTRAL GREAT LAKES. TEMPERATURES WILL THEN EDGE BACK DOWN INTO THE
80S SATURDAY/SUNDAY AS THE FRONT SETTLES INTO THE REGION AND CLOUDS
AND THUNDERSTORMS WILL BE MORE PREVALENT. THIS COOLING TREND WILL
PERSIST INTO EARLY NEXT WEEK AS THE UPPER LOW FORMS. WOULD EXPECT
HIGHS BACK CLOSER TO 80 DEGREES IN MANY AREAS.

&&

.MARINE...

A WEAK FRONTAL BOUNDARY WILL REMAIN DRAPED OVER SOUTHERN LAKE HURON
AND SOUTHERN LOWER MICHIGAN THROUGH TONIGHT...WITH SCATTERED SHOWERS
AND THUNDERSTORMS POSSIBLE. THIS FRONT WILL BEGIN LIFTING NORTH BY
THURSDAY AND STALL OVER NORTHERN LOWER MICHIGAN/NORTHERN LAKE HURON
ON FRIDAY...WITH ADDITIONAL SHOWERS/THUNDERSTORMS FOCUSED OVER THE
NORTHERN HALF OF LAKE HURON. SOUTHWEST FLOW WILL INCREASE LATE IN
THE DAY THURSDAY INTO FRIDAY AS THE FRONT MOVES NORTH. GUSTS WILL
APPROACH 20 KNOTS ON THE IMMEDIATE LAKE HURON SHORELINE BY THURSDAY
EVENING...AND BY FRIDAY...STRONGER FLOW MAY ALLOW 20-25 KNOT GUSTS
TO PENETRATE FURTHER INTO THE NEARSHORE WATERS. THIS MAY VERY WELL
REQUIRE SMALL CRAFT ADVISORIES...ESPECIALLY OVER SAGINAW BAY WHERE
SOUTHWEST FLOW WILL CHANNEL UP THE BAY. THIS FRONT WILL THEN SINK
BACK SOUTH OVER THE WEEKEND...SPREADING SHOWERS/THUNDERSTORMS INTO
THE SOUTHERN HALF OF LAKE HURON...AND TO SOME EXTENT...TO WESTERN
LAKE ERIE.

&&

.PREV DISCUSSION...ISSUED 139 PM EDT WED JUL 16 2008

AVIATION...

NOTE...EARLIER UPDATE DISCUSSION IS BELOW.

AN EXTREMELY UNSTABLE AIRMASS WILL ALLOW FOR A THREAT OF
THUNDERSTORMS THIS AFTERNOON. HAVE ADDED TIMING WITH THREE HOUR
TEMPO GROUPS. EXPECTING ISOLATED TO SCATTERED ACTIVITY TO FIRE A
TOUCH EARLIER (SOUTH OF A STATIONARY FRONT) FOR THE DETROIT TAF
SITES. LARGER SCALE FORCING WILL EXIT WISCONSIN AND IS EXPECTED TO
ARRIVE AROUND 00UTC FOR KMBS/KFNT. OUTSIDE OF ANY
THUNDERSTORMS...CONDITIONS WILL REMAIN VFR WITH LIGHT SURFACE
WINDS.
