AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
338 AM EDT MON APR 16 2012

.SHORT TERM...TODAY AND TONIGHT

SHOWERS AND EMBEDDED THUNDERSTORMS CONTINUE TO GRADUALLY WEAKEN AS
THEY SHIFTS NORTHEAST INTO THE AREA IN ADVANCE OF A PRE-FRONTAL
TROUGH AND PARENT LOW PRESSURE SYSTEM. THIS ACTIVITY WILL REMAIN
FOCUSED OVER THE NORTHWEST CWA EARLY THIS MORNING AND THEN SHIFT
OVER THE REMAINDER OF THE CWA BEFORE DISSIPATING BY MID MORNING.
ADDITIONAL SHOWERS WILL BE POSSIBLE LATE TODAY...ESPECIALLY OVER THE
NORTHERN CWA AS THE AFOREMENTIONED LOW PRESSURE SYSTEM TRACKS OVER
THE NORTHERN GREAT LAKES AND MOISTURE WRAPS BACK INTO PORTIONS OF
LOWER MICHIGAN AROUND THIS LOW.

THE MORE IMPORTANT ASPECT OF THIS SYSTEM WILL BE THE GUSTY SOUTHWEST
WINDS THAT DEVELOP WITHIN DRY SLOT TO THE SOUTH OF THIS LOW TRACK
OVER THE CWA. WITH BEST MIXING DURING THE DAY...WILL MOSTLY LIKELY
SEE A PERIOD THIS AFTERNOON WHERE WIND GUSTS REACH 45 MPH IN MANY
LOCATIONS. WILL BE ISSUING A WIND ADVISORY FOR THESE CONDITIONS.

MILD TEMPERATURES IN THE 60S TO LOWER 70S MID AFTERNOON BEFORE
COOLER AIR BEGINS FILTERING INTO THE AREA. THE CORE OF THIS COLD
AIRMASS WILL PASS THROUGH THE AREA TONIGHT...AND LEAD TO MINIMUM
TEMPERATURES FROM THE LOWER 30S OVER THE NORTHERN CWA TO MID TO
UPPER 30S FROM METRO DETROIT SOUTH.

&&

.LONG TERM...

A STRONG UPPER WAVE IS PROGGED TO ROLL THROUGH SOUTHERN LOWER
MICHIGAN TUESDAY MORNING...BUT HIGH STATIC STABILITY IN PLACE WILL
PRECLUDE ANY TANGIBLE RESPONSE IN THE LOW LEVELS...AS HIGH PRESSURE
BUILDS IN BEHIND THIS WAVE FOR THE AFTERNOON HOURS. CU RULES VARY
AMONGST THE MODELS...BUT CONSENSUS SUGGESTS FEW DIURNAL
CLOUDS...WHICH SEEMS A BIT TOUGH TO BELIEVE WITH COLD 850 MB TEMPS
OF -2 TO -4 C TO START THE DAY. ASSUMING MOSTLY SUNNY SKIES
PREVAIL...SEE NO REASON WHY MAXES WILL NOT MAKE IT INTO THE MID
50S...IN LINE WITH LATEST MAV GUIDANCE.

FAVORABLE RADIATING NIGHT IN STORE FOR TUESDAY NIGHT AS THE SURFACE
HIGH PERSISTS AND SHORTWAVE RIDGING ALOFT IS IN PLACE. ONCE
AGAIN...NO BIG COMPLAINTS WITH MAV GUIDANCE.

MODERATE WARM ADVECTION PATTERN ON WEDNESDAY AHEAD OF AN UPPER
WAVE MOVING INTO THE WESTERN GREAT LAKES...AND EXPECT TEMPS TO CLIMB
INTO THE 60S WITH THE FAVORABLE SOUTHERLY FLOW...EVEN WITH A
CANOPY OF WARM ADVECTION HIGH/MID CLOUDS LIKELY OVERSPREADING THE
AREA...AS GFS INDICATING 925 MB TEMPS ON THE ORDER OF 11 TO 12.5
C.

THE SHORTWAVE TROUGH WILL BE TRACKING THROUGH THE NORTHERN GREAT
LAKES WEDNESDAY NIGHT...AND THERE IS LITTLE IN THE WAY OF HEIGHT
FALLS OVER SOUTHERN LOWER MICHIGAN. THUS...THE SURFACE COLD FRONT IS
TRENDING TO WASH OUT...AND CERTAINLY CAN NOT JUSTIFY MORE THAN
CHANCE POPS. WITH LITTLE AIRMASS CHANGE AS WE HEAD INTO
THURSDAY...LOOKING FOR TEMPS AGAIN TO SNEAK INTO THE LOWER 60S.

BIG COOL DOWN FOR THE WEEKEND CONTINUES TO BE ADVERTISED BY LATEST
EUROPEAN SOLUTION...AS AMPLIFIED LONGWAVE TROUGH/CUTOFF SETS
UP SHOP ACROSS THE EASTERN HALF OF THE CONUS. MULTIPLE OPPORTUNITIES
FOR MINS TO HIT THE FREEZING MARK...WITH DAYTIME TEMPS NO BETTER
THAN THE 50S.

&&

.MARINE...

SOUTHWEST WINDS WILL INCREASE TODAY AS LOW PRESSURE TRACKS INTO THE
NORTHERN GREAT LAKES. WHILE A RELATIVELY STABLE MARINE LAYER WILL
LIMIT WIND GUSTS INTO EARLY THIS EVENING...STILL EXPECT GUSTS TO
TOUCH GALE FORCE...ESPECIALLY NEAR THE SHORE WITH SUCH GOOD MIXING
TO THE SURFACE OVER LAND. STRONG COLD AIR ADVECTION IN THE WAKE OF
DEPARTING LOW PRESSURE BY THIS EVENING WILL BRING A BETTER SETUP FOR
GALES OVER NORTHERN LAKE HURON. WILL ISSUE A GALE WARNING FOR
SOUTHERN LAKE HURON AND POINTS SOUTH FROM LATE MORNING INTO EARLY
THIS AFTERNOON...WITH GALES HOLDING OFF FOR NORTHERN LAKE HURON
UNTIL THIS EVENING WITH GALES MOST LIKELY CONTINUING INTO THE
OVERNIGHT HOURS. WINDS AND WAVES WILL DECREASE TUESDAY AS HIGH
PRESSURE BUILDS IN FROM THE WEST.

&&

.AVIATION...ISSUED 1254 AM EDT MON APR 16 2012

//DISCUSSION...

DEEP/MOIST SOUTHWEST FLOW WILL REMAIN FIRMLY POSITIONED ACROSS
SOUTHEAST MICHIGAN THROUGH THE MORNING HOURS.  ELONGATED AREA OF
SHOWERS AND THUNDERSTORMS WILL GRADUALLY SHIFT EAST ACROSS LOWER
MICHIGAN DURING THIS TIME.  CONFIDENCE IS HIGH ENOUGH TO INCLUDE
A THUNDER MENTION FROM PTK NORTHWARD PER LATEST RADAR TRENDS...BUT
WILL HOLD OFF ACROSS THE DETROIT CORRIDOR GIVEN CONTINUED CONCERNS
THAT THUNDERSTORM COVERAGE MAY DIMINISH CONSIDERABLY AS THIS
MOISTURE ARRIVES TOWARD DAYBREAK.  STRENGTHENING WIND FIELD WILL
RESULT IN A PERIOD OF LOW LEVEL WIND SHEAR ABOVE THE STABLE LAYER
THROUGH MID MORNING. STRONG/GUSTY SOUTHWEST WINDS WILL DEVELOP ON
MONDAY UNDER DEEP MIXING.  POTENTIAL FOR A PERIOD OF SUSTAINED 25
KNOTS WITH GUSTS 35-40 KNOTS FROM MID AFTERNOON INTO THE EARLY
EVENING.  WINDS SHIFT TO WESTERLY BEHIND A STRONG COLD FRONTAL
PASSAGE BY EVENING.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN CEILINGS FALLING BELOW 5K FT THIS MORNING.

* LOW CONFIDENCE ON THUNDERSTORMS THIS MORNING.

* MEDIUM CONFIDENCE SOUTHWEST WINDS WILL REACH 25 KNOTS...WITH GUSTS
TO 35 KNOTS FROM 230-250 DEG THIS AFTERNOON.
