AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
127 PM EDT FRI APR 11 2008

.AVIATION...

THE TAF FORECAST FOR MBS REMAINS VERY DIFFICULT THIS AFTERNOON AS
WARM FRONT GETS HANG UP IN THAT VICINITY. ELSEWHERE...SCATTERED
TO NUMEROUS THUNDERSTORMS ARE EXPECTED TO TRAVERSE ACROSS
SOUTHEAST MICHIGAN LATE THIS AFTERNOON. A FEW OF THESE STORMS ARE
EXPECTED TO BE SEVERE. THUNDERSTORMS WILL END DURING/BY EARLY
EVENING...WITH LOW STRATUS DECK MOVING IN OVERNIGHT. CEILINGS ARE
EXPECTED TO BE AT LEAST LOW MVFR BY MORNING...WITH THE POTENTIAL
FOR IFR CEILINGS DURING TOMORROW WITH RAIN SHOWERS.

&&

.PREV DISCUSSION...ISSUED 948 AM EDT FRI APR 11 2008

UPDATE...

STACKED/NEARLY STACKED LOW PRESSURE SYSTEM CENTERED OVER THE
MIDWEST/IOWA THIS MORNING. NUMEROUS REPORTS OF SEVERE
WEATHER...INCLUDING TORNADOES OVER SOUTHERN IOWA/NORTHERN
MISSOURI/FAR WESTERN ILLINOIS YESTERDAY AFTERNOON/EVENING. OF
COURSE...THE MID/UPPER LEVEL CIRCULATION WAS MUCH TIGHTER
YESTERDAY...AND WILL CONTINUE TO UNRAVEL TODAY. HOWEVER...THE 500
MB COLD POOL REMAINS IMPRESSIVE...WITH 12Z RAOBS CHECKING IN
BETWEEN -20 TO -23 C OVER THE WESTERN GREAT LAKES. 12Z DTX
SOUNDING SHOWED A 500 MB TEMP OF -13 C AT 500 MB...AND WILL BE
FALLING THROUGH THE DAY...LEADING TO VERY STEEP MID LEVEL LAPSE
RATES. STILL LOOKING FOR GIRTHY CAPES OF AT LEAST A 1000 J/KG IN
THE LOW/MID LEVELS...SUPPORTING STRONG UPDRAFTS.

WATER VAPOR IMAGERY SHOWS WELL DEFINED DRY SLOT MAKING A BEE-LINE
TOWARD SOUTHEAST MICHIGAN. EQUALLY IMPRESSIVE IS THE LEFT EXIT
REGION OF A 110 KNOT JET MAX (500 MB) WHICH IS EXPECTED TO MOVE OVER
SOUTHEAST MICHIGAN THIS AFTERNOON. VISIBLE SATELLITE IMAGERY ALREADY
SHOWS CLEARING MOVING INTO THE STATE...THUS CONFIDENCE IS HIGH WILL
BE DESTABILIZE ENOUGH TO SUPPORT SEVERE THUNDERSTORMS IN SOUTHERN
LOWER MICHIGAN. ZONES AND HWO HAVE BEEN UPDATED. THE BIGGEST
STICKING POINT IS THE EXACT LOCATION AND THE EXTENT. AS PREVIOUS AFD
MENTIONED...STILL BELIEVE THE I-69 CORRIDOR IS AT GREATEST RISK FOR
TORNADIC ACTIVITY...BUT DISCRETE LOW TOPPED SUPERCELLS REMAIN
POSSIBLE FARTHER SOUTH.

PREV DISCUSSION...ISSUED 415 AM EDT FRI APR 11 2008

SHORT TERM...TODAY

MAJOR UPPER LEVEL STORM SYSTEM SPINNING UP WELL WEST OF THE AREA
WILL PROVIDE ACTIVE WEATHER TODAY AS SEVERAL ROUNDS OF PRECIPITATION
ROTATE THROUGH THE AREA.

SHOWERS WILL CONTINUE TO FUNNEL NORTH/NORTHEAST THROUGH THE AREA THIS
MORNING...WITH A FEW RUMBLES OF THUNDER ALSO POSSIBLE. THIS ACTIVITY
WILL SHIFT EAST STEADILY AS A MAJOR DRY SLOT ROTATES INTO THE AREA.
DURING THIS TIMEFRAME...FROM MID MORNING INTO EARLY AFTERNOON...A
WARM FRONT WILL LIFT THROUGH THE REGION...STALLING NORTH OF I 69 BY
LATE AFTERNOON. THIS WILL ALLOW FOR A MILD AIRMASS TO LIFT INTO THE
AREA WITH TEMPERATURES CLIMBING INTO THE UPPER 60S/LOWER 70S SOUTH
OF THE FRONT...WHILE STRUGGLING INTO THE 50-55 DEGREE RANGE FROM
PARTS OF THUMB BACK INTO THE SAGINAW VALLEY.

AFTER A BREAK IN THE SHOWER/THUNDERSTORM ACTIVITY AFTER THIS WARM
FRONT PASSES...ANOTHER ROUND OF CONVECTION IS EXPECTED FROM MID
AFTERNOON INTO THE EVENING AS SURFACE LOW FORMS ALONG AN OCCLUDED
FRONT AND BOTH TRACK THROUGH THE REGION. MODELS HAVE GENERALLY
BACKED OFF SLIGHTLY ON THE DEGREE OF LOW LEVEL MOISTURE THAT WORKS
INTO THE AREA BEHIND THE WARM FRONT...AND SURFACE OBSERVATIONS IN
ILLINOIS EARLY THIS MORNING SEEM TO BEAR THIS TREND OUT SOMEWHAT AS
DEWPOINTS ARE FALLING BACK THROUGH THE 50S...AFTER TOPPING 60 THIS
PAST EVENING. WITH THE TRACK OF THE AFOREMENTIONED LOW PRESSURE OVER
THE SAGINAW VALLEY...EAST/SOUTHEAST FLOW SHOULD VEER TO THE SOUTH TO
SOUTHWEST PRETTY EARLY IN THIS EVENT AND ALLOW THIS DRIER AIR TO
WORK INTO MUCH OF THE CWA...ESPECIALLY OVER SOUTHEAST PORTIONS OF
THE AREA.

ALTHOUGH THIS WILL LIMIT THE COVERAGE OF THUNDERSTORMS...AND ALSO
THE SEVERE POTENTIAL TO SOME EXTENT...STILL EXPECT AN ACTIVE
AFTERNOON AND AGREE WITH THE SPC OUTLOOK OF A SLIGHT RISK OF SEVERE
THUNDERSTORMS AS THIS SECOND BATCH OF SHOWERS/THUNDERSTORMS PROGRESS
THROUGH THE AREA. AS IT STANDS NOW...AREAS NORTH OF FLINT WILL MOST
LIKELY SEE THE BEST ORGANIZED CONVECTION AS LOW LEVEL WINDS REMAIN
BACKED FROM THE SOUTHEAST LONGER AND BETTER LOW LEVEL MOISTURE IS
ABLE TO POOL ON THE CRUX OF THE STALLED WARM FRONT AND APPROACHING
SURFACE LOW. IN THIS REGION...MID LEVEL FLOW IS NOT AS OVERPOWERING
EITHER WITH H5 SOUTHWEST FLOW OF 50-60 KNOTS -VS- 80-100 KNOTS OVER
THE SOUTHEAST CWA. WITH MODEST INSTABILITY...ML CAPES OF 500-1000
J/KG...THESE STRONG WINDS MAY LIMIT SUPERCELL STRUCTURE AS UPDRAFTS
ARE LIKELY TO BE DISRUPTED. THIS WILL BE LESS OF A FACTOR OVER THE
SAGINAW VALLEY NEAR THE LOW PRESSURE...SO WOULD PICK AREAS BETWEEN
FLINT/SAGINAW INTO PARTS OF THE THUMB AS THE AREA TO WATCH FOR THE
BEST SEVERE WEATHER POTENTIAL...INCLUDING A POSSIBLE TORNADO. THIS
IS ASSUMING THE WARM FRONT IN FACT MAKES IT THAT FAR NORTH. FURTHER
SOUTH...ANY THUNDERSTORMS WOULD MORE LIKELY PRODUCE DAMAGING WINDS
AND PERHAPS LARGE HAIL. THIS WILL HAVE TO BE RE-EVALUATED BASED ON
THE EVENTUAL POSITION OF THESE SURFACE FEATURES...AND DEGREE OF LOW
LEVEL MOISTURE/INSTABILITY...BY MID AFTERNOON.

LONG TERM...TONIGHT THROUGH NEXT THURSDAY

WEEKEND PRECIPITATION TYPE AND POTENTIAL REMAINS THE FOCI OF THE
LONG TERM.

SURFACE TRIPLE POINT AND COLD FRONT WILL EXIT THE FORECAST AREA THIS
EVENING BRINGING AN END TO DEEPER MOISTURE (ALREADY SHUNTED EAST OF
LAKE HURON) AND LOW LEVEL CONVERGENT FORCING. ON THE OTHER
HAND...THE SURFACE AND MIDLEVEL THERMAL TROUGHS DO REMAIN ACROSS THE
TRI CITIES/NORTHERN THUMB WITH THE MASSIVE LOW VERTICALLY STACKED.
THEREFORE...WILL CONTINUE THE INHERITED CHANCE POP MENTION FOR LIGHT
RAIN SHOWERS. TEMPERATURES WILL DROP CONTINUOUSLY OVERNIGHT IN CAA
REGIME...RANGING FROM UPPER 30S NORTH TO LOW 40S SOUTH.

THE OLD CENTER OF VORTICITY WORKS OUT OF WISCONSIN THROUGH AREAS OF
SOUTHEASTERN MICHIGAN ON SATURDAY.  THE COMBINATION OF MIDLEVEL
DEFORMATION/CVA/AND DIURNAL LAPSE RATES WILL PROVIDE A FAVORABLE
ENVIRONMENT FOR SHOWERY PRECIPITATION ON SATURDAY. THE SURFACE
REFLECTION/TROUGH HANGING BACK INTO THE GREAT LAKES IS QUITE
PRONOUNCED SO INTRODUCED NUMEROUS MENTION WITH HIGHER CONFIDENCE.
OVERCAST...OFF AND ON RAIN...WITH HIGHS IN THE LOW TO MID 40S
SIGNALS A RATHER UNPLEASANT DAY. THE DEPTH OF THE NEAR SURFACE WARM
LAYER WILL REMAIN SUFFICIENT FOR RAIN ACROSS THE AREA. SATURDAY
NIGHT...CONTINUED CAA AND LOSS OF INSOLATION WILL ALLOW FOR A
CHANGEOVER TO ALL SNOW .  ATTM...NOT EXPECTING MUCH IN THE WAY OF
ANY SNOWFALL ACCUMULATIONS...BUT GIVEN THE LINGERING SURFACE TROUGH
ACROSS THE FAR SOUTH DID INCREASE POPS TO LIKELY. LOW TO MIDLEVEL
TEMPERATURES WILL BE COLD ON SUNDAY...CHARACTERIZED BY 850MB
TEMPERATURES OF ROUGHLY 1 STANDARD DEVIATION BELOW NORMAL.  THE
SURFACE TROUGH SHOULD RAPIDLY WEAKEN AS THE VORT FINALLY SHEARS
OUT...WHICH WILL ALLOW FOR GREATER EAST TO NORTHEASTERLY FLOW.  NOT
EXPECTING MUCH WARMTH WITH HIGHS ONLY REACHING THE MID TO UPPER 30S
NEAR LAKE HURON AND LOW 40S SOUTH.

MIDLEVEL HEIGHT RISES WILL BE ON THE INCREASE MONDAY...WITH A BLOCKY
PATTERN RESULTING FOR MUCH OF THE WEEK. QUIET WEATHER IN STORE AND A
MODERATING TREND IN TEMPERATURES...50S TUESDAY TO NEAR 60 WEDNESDAY.

MARINE...

DEEPENING LOW PRESSURE OVER THE MID-MISSISSIPPI VALLEY WILL MOVE
INTO THE WESTERN LAKES REGION TONIGHT...WITH A STRONG EASTERLY FLOW
PERSISTING...PARTICULARLY OVER THE NORTHERN TWO-THIRDS OF LAKE
HURON. TO THE SOUTH OF THIS...THE GRADIENT FORCING WILL NOT BE AS
STRONG...AND WINDS WILL SHIFT TO THE SOUTHWEST TONIGHT. CURRENT
MARINE HEADLINES WILL REMAIN THE SAME...AND WILL ADD A SMALL CRAFT
ADVISORY TO WESTERN LAKE ERIE THROUGH THIS EVENING. AS ALTHOUGH THE
CURRENT GUSTY WINDS WILL SUBSIDE...WAVES SHOULD REMAIN RATHER HIGH
THOUGH THE AREA...WITH WINDS INCREASING AGAIN LATER THIS AFTERNOON
AS THEY SHIFT TO THE SOUTHWEST IN BEHIND AS PASSING SURFACE FRONT.
