AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
119 PM EDT THU OCT 31 2013

.AVIATION...

//DISCUSSION...

SOUTHEASTERN MICHIGAN REMAINS WITHIN THE FIREHOSE OF THE WARM
CONVEYOR AHEAD OF THE APPROACHING STRONG LOW PRESSURE SYSTEM.
GENERAL VFR/MVFR CIGS AND VSBYS WILL BE THE NORM WITH PERIODS OF
RAIN THROUGH THIS EVENING. PASSING BOUTS OF BRIEF IFR CIGS/VSBYS
CONDITIONS ARE ALSO POSSIBLE IN OCCASIONAL HEAVIER ACTIVITY.

THE MAIN AVIATION ITEM OF CONCERN IS THE THE POTENTIAL FOR HIGH
IMPACT WIND THIS EVENING IN TOW OF A COLD FRONT THAT WILL SLIDE
EASTWARD THROUGH LOWER MICHIGAN. THE POTENTIAL EXISTS FOR
SOUTHWESTERLY WIND GUSTS OF UP TO/IN EXCESS OF 50 KNOTS.  LATEST
TIMING OF THE WIND SURGE/COLD FRONT IS EXPECTED TO OCCUR AT ROUGHLY
04-05Z FOR ALL SITES. ADDITIONALLY FOR THE NORTH HALF...INCLUDING
KMBS AND KFNT A SECONDARY ROUND OF COLD AIR ADVECTION BETWEEN 10-14Z
WILL BRING AN ADDITIONAL OPPORTUNITY FOR WINDS TO APPROACH 50 KNOTS.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN SFC WINDS OF 200 BECOMING 240 OF AT LEAST 45
KNOTS BETWEEN 4-8Z.

* HIGH CONFIDENCE IN CEILINGS BELOW 5000 FEET THROUGH TONIGHT.

* LOW CONFIDENCE IN COVERAGE OF THUNDERSTORMS THIS EVENING.

&&

.PREV DISCUSSION...ISSUED 704 AM EDT THU OCT 31 2013

UPDATE...

GOING FORECAST FOR SOUTHEAST MICHIGAN REMAINS IN DECENT SHAPE AS
PERIODS OF RAIN SHOWERS CONTINUE TO FUNNEL INTO THE AREA. ANY
BREAKS SOUTH OF THE WARM FRONT SEEM TO BE FLEETING AS ADDITIONAL
ACTIVITY LIFTS INTO AREA FROM INDIANA/OHIO.

DID UPDATE MARINE TO INCLUDE A STORM WARNING IN SEVERAL ZONES IN
MIDDLE/NORTHERN LAKE HURON. 06Z NAM/GFS RUNS ARE VERY CLOSE IN LOW
TRACK AND INTENSITY...BASICALLY BOMBING NEARLY 20 MBS IN 12 HOURS
IT LIFTS FROM LAKE MICHIGAN TO NORTHERN LAKE HURON LATE TONIGHT.

PREV DISCUSSION...ISSUED 344 AM EDT THU OCT 31 2013

SHORT TERM...TODAY AND TONIGHT

BUSY PERIOD THIS HALLOWEEN AS A POTENT LOW PRESSURE SYSTEM LIFTS
INTO THE AREA LATER TODAY INTO TONIGHT. RAIN HAS ALREADY OVERSPREAD
THE REGION EARLY THIS MORNING AS THE LEADING WARM FRONTAL BOUNDARY
LIFTS NORTH INTO THE CENTRAL GREAT LAKES. THETA-E RIDGE WILL FUNNEL
RIGHT OVER AREA MUCH OF THE DAY AS THE WARM FRONT LIFTS NORTH AND
EVENTUALLY CLEARS THE ENTIRE CWA THIS AFTERNOON. SO...PERIODS OF
SHOWERS CAN BE EXPECTED THROUGH THE DAY. WHILE THE WHOLE AREA WILL
LIKELY SHARE IN THIS MOISTURE...UPPER RIDGING WILL BRUSH THE FAR
SOUTHEAST CWA AND KEEP THE HEAVIEST/MOST WIDESPREAD RAIN FOCUSED
OVER ABOUT THE NORTHWEST 2/3RD OF THE AREA.

WHILE A BUSY DAY INDEED...THE MAIN CONCERN(S) WITH THIS STORM SYSTEM
OCCUR THIS EVENING INTO THE OVERNIGHT HOURS AS THE RAPID DEEPENING
PHASE ENSUES AS JETLET WRAPS UP THE SOUTHEAST SIDE OF MEAN UPPER
LEVEL TROUGH AND STRONG CYCLOGENESIS RESULTS. MODELS VARY SLIGHTLY
ON THE EVOLUTION/TRACK OF THIS STRENGTHENING LOW PRESSURE...WHICH
SHOULD LIFT OVER/JUST NORTH OF THE AREA THIS EVENING AND RACES INTO
NORTHERN LAKE HURON/SOUTHERN ONTARIO OVERNIGHT.

WITH THIS TRACK...THE AREA WILL REMAIN IN THE WARM SECTOR ONCE THE
WARM FRONT LIFTS INTO NORTHERN LOWER MICHIGAN. THE WEAK TO MODEST
INSTABILITY THAT DEVELOPS WITHIN THIS MILD/MOIST AIRMASS WILL SET THE
STAGE FOR THE FIRST REAL CONCERN WITH THIS STORM AS FORCING ALONG A
STRONG TROUGH/COLD FRONT THIS EVENING WILL ACT ON THIS AIRMASS (WITH
BEST INSTABILITY LIKELY POOLED ALONG/IN ADVANCE OF THIS BOUNDARY) TO
SPARK A BAND OF STRONG TO POSSIBLY SEVERE THUNDERSTORMS. GIVEN THE
TIME OF THE YEAR...THIS WILL BE A NARROW LINE OF CONVECTION THAT
RACES THROUGH THE AREA RATHER QUICKLY...ENHANCING THE ALREADY GUSTY
SYNOPTIC SCALE WINDS IN PLACE OVER THE AREA. IT IS NOT OUT OF THE
QUESTION TO SEE WIND GUSTS TO 50 MPH OR MORE.

OVERALL WIND FIELD THEN CONTINUES TO INCREASE FROM LATE EVENING INTO
THE OVERNIGHT AS THE LOW PRESSURE BOMBS OUT TO 975 MB OR LESS AND A
SIGNIFICANT PRESSURE SURGE TRANSLATES ACROSS THE AREA. EXPECT WIND
GUSTS OVERNIGHT INTO THE 35-45 MPH RANGE AND MAY VERY WELL HAVE TO
ISSUE A WIND ADVISORY FOR PORTIONS OF THE AREA. FEEL IT IS PRUDENT
TO ALLOW THE DAYSHIFT TO STUDY THE LATEST LOW PRESSURE TRACK TO PIN
DOWN THE SWAP OF STRONGEST WIND GUSTS AS MUCH AS POSSIBLE...SO WILL
FORGO A HEADLINE ATTM. SUFFICE IT TO SAY...ANY LULL THAT OCCURS IN
THE WAKE OF THE PASSING CONVECTION IN THE EVENING WILL BE BRIEF AND
EXPECT WINDY CONDITIONS TO INTENSIFY OVERNIGHT AGAIN.

WITH SUCH A MILD AIRMASS ADVECTING INTO THE AREA...TEMPERATURES WILL
BE QUITE MILD FOR THE LAST DAY OF OCTOBER...TOPPING 60 DEGREES OVER
THE ENTIRE CWA AND CLIMBING INTO THE MID/UPPER 60S DETROIT SOUTH OR
SO. EVEN SO...THESE VALUES REMAIN WELL BELOW RECORD TEMPERATURES
WHICH ARE GENERALLY IN THE UPPER 70S ACROSS SOUTHEAST MICHIGAN TODAY.

LONG TERM...

OUR POTENT STORM SYSTEM WILL QUICKLY BE PULLING AWAY FROM THE
AREA ON FRIDAY. STILL...RESIDUAL LOW LEVEL MOISTURE/CYCLONIC FLOW
WITH 850 MB TEMPS FALLING SUB ZERO BY DAY'S END WILL SUPPORT PLENTY
OF LOW CLOUDS AND LIKELY SCATTERED LIGHT SHOWERS. SCATTERED SHOWERS
ARE EXPECTED TO BE A BIT MORE ROBUST FRIDAY NIGHT AS NEXT SHORTWAVE
TROUGH SWINGS THROUGH THE MIDWEST AND INTO THE WESTERN OHIO
VALLEY...WITH A SURFACE COLD FRONT PROGGED TO COME THROUGH ON
SATURDAY....SENDING 850 MB TEMPS DOWN INTO THE -6 TO -8 C RANGE OVER
THE SECOND HALF OF THE WEEKEND...PER 00Z EURO/GFS. LOW LEVEL
CONVERGENCE ALONG THE EASTERN THUMB SHORELINE SHOULD LEAD TO SOME
SNOW AND RAIN SHOWERS BEFORE SURFACE HIGH BUILDS OVER LAKE HURON
SUNDAY AFTERNOON. SUNDAY NIGHT LOOKS TO BE THE COLDEST NIGHT OF THE
WEEK...AND TEMPS HAVE GOOD SHOT TO FALL INTO 20S IF THERE ARE NO
CLOUDS AROUND BEFORE RETURN FLOW AROUND THE DEPARTING HIGH KICKS IN.

CLASSIC UPPER LEVEL PATTERN SETUP NEXT WEEK WITH LONGWAVE TROUGH
WEST OF THE MISSISSIPPI AND RIDGE EAST. RESULTING STRONG RETURN FLOW
WILL ALLOW FOR MODERATING TEMPERATURES AND INCREASING MOISTURE FROM
THE GULF OF MEXICO...WITH GOOD CHANCE OF SHOWERS DURING THE MID TO
LATE WEEK PERIOD.

MARINE...

SMALL CRAFT ADVISORIES REMAIN IN EFFECT FOR THE NEARSHORE WATERS
TODAY INTO THIS EVENING AS SOUTHEAST WINDS SHIFT TO THE SOUTH AND
STRENGTHEN AS A WARM FRONT LIFTS NORTH THROUGH THE AREA. NUMEROUS
SHOWERS AND AN OCCASIONAL THUNDERSTORM WILL ALSO PERSIST ALONG AND
BEHIND THIS FRONT AS A MILD AND MOIST AIRMASS OVERSPREADS THE AREA.
LOW PRESSURE WILL THEN DEEPEN RAPIDLY AS IT SHIFTS INTO THE REGION
THIS EVENING AND THEN TRAVERSES LAKE HURON ON ITS WAY TO SOUTHERN
ONTARIO FRIDAY MORNING. WINDS WILL BECOME SOUTHWEST AND INCREASE TO
GALES AS THIS LOW PULLS A COLD FRONT THROUGH THE AREA TONIGHT. GALE
WARNINGS HAVE BEEN ISSUED FOR ALL MARINE AREAS IN ANTICIPATION OF
THIS SCENARIO. DEPENDING ON THE EXACT TRACK OF THIS LOW...THERE MAY
EVEN BE A BRIEF PERIOD OF WIND GUSTS APPROACHING STORM FORCE EARLY
FRIDAY MORNING IN THE IMMEDIATE WAKE OF THE LOW PRESSURE. WINDS WILL
DIMINISH SUBSTANTIALLY LATE FRIDAY INTO FRIDAY NIGHT AS THIS SYSTEM
RACES INTO EASTERN CANADA.
