AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1203 AM EDT WED SEP 19 2012

.AVIATION...

//DISCUSSION...

VFR CONDITIONS WILL CONTINUE IN THE FORM OF ALTOCU THAT WILL DRIFT
OVER THE REGION FROM LAKE MICHIGAN, MAINLY SOUTH OF FLINT DURING THE
NIGHT. THE CLOUDS WILL COINCIDE WITH A DIMINISHING AND BACKING WIND
THROUGH THE MORNING. THIS WILL INDICATE THE BEGINNINGS OF WARMER
AIR RETURNING TO THE GREAT LAKES WHICH WILL BECOME MORE EVIDENT BY
AFTERNOON AS VFR MID CLOUDS THICKEN AND SOUTH WIND INCREASES
STEADILY THROUGH THE DAY. THE SOUTHERLY FLOW WILL OCCUR AHEAD OF
THE NEXT COLD FRONT THAT IS NOT EXPECTED TO SWEEP INTO SE MICHIGAN
UNTIL THE EARLY MORNING HOURS THURSDAY.

//DTW THRESHOLD THREATS...

* NONE.

&&

.PREV DISCUSSION...ISSUED 1103 PM EDT TUE SEP 18 2012

UPDATE...

THE EVENING UPDATE ISSUED A FROST ADVISORY FOR THE SAGINAW VALLEY
TO HEIGHTEN AWARENESS OF EARLY SEASON CONDITIONS FOR THE BENEFIT
OF AGRICULTURAL INTERESTS WITH GREATER SENSITIVITY. LIGHT WESTERLY
WIND AND WARM GROUND TEMPERATURES REMAIN NEGATIVE FACTORS FOR
FROST FORMATION BUT IT WILL BE A CLOSE CALL. OBSERVATIONS IN
CENTRAL LOWER MICHIGAN ALREADY INDICATE WIND DECOUPLING WHICH IS
LIKELY TO OCCUR FARTHER EAST WITH TIME AND PERMIT A LONGER PERIOD
OF RADIATIONAL COOLING. PATCHY FROST IS ALSO MENTIONED TOWARD THE
INTERSTATE 69 CORRIDOR THROUGH THE INTERIOR THUMB AWAY FROM THE
WARMING INFLUENCE OF SAGINAW BAY.

PREV DISCUSSION...ISSUED 324 PM EDT TUE SEP 18 2012

SHORT TERM...TONIGHT

STOUT NORTHWESTERLY FLOW WITHIN THE CONVECTIVE BOUNDARY LAYER WILL
HELP SUSTAIN LAKE CLOUDS THROUGH LATE THIS EVENING EVEN AS SHOWERS
DISSIPATE OVER THE NEXT COUPLE OF HOURS. THIS WILL PARTICULARLY BE
THE CASE NORTH OF THE I-69 CORRIDOR WHERE THE ARRIVAL OF DRY AIR
CAPABLE OF SHUTTING OFF LAKE EFFECTS WILL NOT OCCUR UNTIL AROUND
MIDNIGHT OR PERHAPS OR SO. FURTHER SOUTH, LOW LEVEL RIDGING IS
FORECAST TO BUILD IN FROM THE SOUTHWEST, WHICH SHOULD ALLOW THE
GRADIENT TO SLACKEN AND WORK AGAINST THE PERSISTENCE OF ANY
LINGERING STRATOCU. THIS EVENING'S SOUTHWEST TO NORTHEAST CLEARING
TREND NOTED IN THE INHERITED FORECAST PACKAGE REMAINS IN TACT.

CLEARING SKIES WILL GIVE WAY TO AN UNSEASONABLY CHILLY NIGHT. LOW
TEMPERATURES THIS MORNING GENERALLY RANGED FROM THE LOW TO MID 30S
UPSTREAM OF LAKE MICHIGAN...WITH A FEW COLDER SPOTS IN NORTHERN MN
DIPPING WELL INTO THE 20S. GIVEN THE MODIFICATION OF THIS AIRMASS AS
IT TRAVERSES LAKE MICHIGAN, THE POTENTIAL FOR CLOUDS THROUGH AT
LEAST A PORTION OF THE NIGHT, AND A SURFACE PRESSURE GRADIENT AROUND
THE PERIPHERY OF THE BUILDING HIGH THAT SHOULD PREVENT FULL
DECOUPLING, ONLY MINOR TWEAKS WERE MADE TO THE INHERITED FORECAST OF
MID TO UPPER 30S...LOW 40S IN DETROIT. THE MULTITUDE OF
INFLUENTIAL VARIABLES INTRODUCES MORE UNCERTAINTY THAN NORMAL TO
TONIGHT'S FORECAST. HOWEVER, IT IS WORTH NOTING IN ANY CASE THAT IF
TEMPERATURES WERE TO DIP A BIT BELOW THE CURRENT FORECAST, FROST
WOULD REMAIN UNLIKELY GIVEN LINGERING CLOUDS, LIGHT WINDS, A WARM
GROUND YET GIVEN THAT IT IS STILL MID-SEPTEMBER. LOWS ARE EXPECTED
TO STAY SAFELY ABOVE THE DAILY RECORDS AT MBS AND FNT BOTH 33
DEGREES), BUT COULD POTENTIALLY BE CHALLENGED AT DTW (38 DEGREES).

LONG TERM...WEDNESDAY THROUGH TUESDAY

SEVERAL VIGOROUS SHORTWAVE WILL DROP SOUTHEAST THROUGH BASE OF THE
NORTHERN STREAM UPPER TROUGH NOW ENTRENCHED OVER THE AREA. AT THE
ONSET...THIS WILL ACTUALLY ALLOW THE MEAN UPPER TROUGH AXIS TO BACK
TO THE WEST DURING THE MIDDLE OF THE WEEK...AND ALLOW FOR MODERATING
TEMPERATURES BACK INTO THE 65 TO 70 DEGREE RANGE THROUGH FRIDAY.
THEREAFTER...THE BASE OF THE TROUGH WILL SETTLE OVER THE CENTRAL
GREAT LAKES OVER THE WEEKEND AS THE UPPER LOW BECOME ANCHORED OVER
THE FAVORED HUDSON BAY REGION...AND A FINAL STRONG SHORTWAVE SPINS
THROUGH THE REGION AROUND THE BASE OF THIS LOW. THIS WILL BRING MUCH
COLDER AIR ON SATURDAY/SUNDAY WITH HIGHS LUCKY TO REACH 60 AND LOWS
CLOSE TO 40. THIS PATTERN WILL THEN GRADUALLY MODERATE EARLY NEXT
WEEK AS THIS SHORTWAVE LIFTS INTO EASTERN CANADA AND THE CORE OF THE
COLDEST AIR ASSOCIATED WITH THE UPPER TROUGH BECOMES FOCUSED FROM
THE NORTHERN LAKES REGION ON INTO ONTARIO.

EACH OF THESE UPCOMING SHORTWAVES WILL BE VERY DYNAMIC (MUCH LIKE
THE LEAD WAVE MOVING THROUGH THE AREA TODAY)...GIVEN THE BAROCLINICITY
OVER CENTRAL NOAM. SO...EVEN THOUGH THE NEXT WAVE WILL TRACK WELL
NORTH OF THE AREA LATE WEDNESDAY INTO EARLY THURSDAY...AND TAKE THE
MAIN RAIN SHIELD WITH IT...THERE SHOULD STILL BE A DECENT SHOT AT
SHOWERS ALONG THE TROUGH AXIS/COLD FRONT AS IT SURGES SOUTH AND EAST
THROUGH THE AREA...ESPECIALLY OVER THE NORTHERN CWA...WITH A CLOSER
PROXIMITY TO THE DYNAMIC LIFT ASSOCIATED WITH THE SYSTEM. A BETTER
CHANCE FOR RAIN FOR THE ENTIRE AREA WILL ARRIVE LATE FRIDAY INTO
FRIDAY NIGHT AS THE NEXT SHORTWAVE IN THIS SERIES PIVOT MUCH FURTHER
TO THE SOUTH AND TRACKS INTO THE AREA FROM THE WEST AS THE CORE THE
THE UPPER TROUGH SETTLES CLOSER TO THE NORTHERN GREAT LAKES.

SHOWER CHANCES WILL CONTINUE OVER THE WEEKEND AS THE COLDEST AIR OF
THE EARLY FALL SEASON DUMPS THROUGH THE AREA AND LAKE EFFECT SHOWERS
ENHANCE ALREADY EXISTING ACTIVITY WITHIN THIS UNSETTLED UPPER LEVEL
PATTERN. IN ADDITION...THE FINAL STRONG SHORTWAVE PUSHING THROUGH
THE AREA WILL LIKELY BRING A 6-12 HOUR WINDOW OF ADDITIONAL SHOWER
ENHANCEMENT SOMETIME DURING THE MIDDLE OF THE WEEKEND.

MARINE...

GUSTY NORTHWEST WINDS OF 25 TO 30 KNOTS WILL PERSIST WITH
SIGNIFICANT WAVE HEIGHTS REMAINING NEAR 6 TO 9 FEET OVER THE OPEN
WATERS OF SOUTHERN LAKE HURON AND 5 TO 7 FEET FROM OUTER SAGINAW BAY
TO PORT HURON THROUGH LATE TONIGHT. ALL SMALL CRAFT ADVISORIES
REMAIN IN EFFECT AND ARE SET TO GRADUALLY EXPIRE BETWEEN THIS
EVENING AND WEDNESDAY MORNING. AFTER A BRIEF REPRIEVE...SOUTHERLY
WINDS WILL INCREASE AHEAD OF THE NEXT SYSTEM LATE ON WEDNESDAY.
DESPITE THE SOUTHERLY FLOW, REMNANT COLD AIR OVER THE WATERS WILL
FACILITATE DEEP MIXING AND GUSTS TO GALES OR NEAR GALES.
HOWEVER...THE TIME WINDOW FOR THIS OCCUR WILL BE SHORT AND GIVEN THE
MARGINAL NATURE OF THE THREAT...NO GALE WATCH WILL BE ISSUED AT THIS
TIME. THE PATTERN WILL REMAIN ACTIVE WITH SEVERAL EPISODES OF GUSTY
NORTHWEST FLOW AND ELEVATED WAVE CONDITIONS LIKELY THROUGH THE
FORECAST PERIOD.
