AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
125 AM EDT FRI APR 19 2013

.AVIATION...

//DISCUSSION...

A STRONG COLD FRONT WILL MOVE THROUGH SE MICHIGAN BEFORE SUNRISE.
THE WIND SHIFT WILL BRING A QUICK BURST OF HEAVY SHOWERS AND 30 TO
35 KNOT WIND GUSTS BEFORE SETTLING BACK SLIGHTLY INTO THE 25 TO 30
KNOT RANGE. THERE ARE NO LIGHTNING STRIKES INDICATED ALONG THE FRONT
IN SUPPORT OF MARGINAL THUNDERSTORM POTENTIAL. UPSTREAM OBSERVATIONS
DO INDICATE A MORE CONVINCING STRETCH OF MVFR CEILING POST FRONT
THAT WILL LAST THROUGH LATE MORNING EVEN AS THE RAIN IS SWEPT
EASTWARD BY THE FRONT. THAT WILL LEAVE SOUTHWEST WIND GUSTS AS THE
THE MAIN AVIATION CONCERN DURING THE REST OF THE DAY. THE PEAK OF
THE WINDS WILL BEGIN BY LATE MORNING AS DAYTIME HEATING DEEPENS THE
BOUNDARY LAYER. LOW LEVEL COLD AIR WILL THEN MAINTAIN GUSTS OFF THE
DAYTIME PEAK BUT STILL AT LEAST 25 KNOTS THROUGH FRIDAY NIGHT.

FOR DTW... SHOWERS WILL BE PERSISTENT THROUGH THE NIGHT AS MOISTURE
POOLS AHEAD OF THE COLD FRONT THAT WILL MOVE THROUGH LOWER MICHIGAN.
SUB-5000 FT CEILING WILL BE TIED TO HEAVIER RAIN SHOWERS UNTIL A
SHORT PERIOD OF MVFR/IFR WITH THE FRONTAL PASSAGE THEN FOLLOWED BY
PERSISTENT MVFR DURING THE MORNING. THUNDERSTORM POTENTIAL REMAINS
LOW EVEN ALONG THE FRONT SUPPORTED BY A LACK OF LIGHTNING STRIKES
OVER THE REGION SINCE SUNSET. SOUTHWEST WIND GUSTS AROUND 35 KNOTS
REMAIN ON TRACK BY MORNING THROUGH THE AFTERNOON.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN CEILING BELOW 5000 FT THROUGH THE MORNING.

* HIGH CONFIDENCE IN WIND GUSTS AROUND 35 KNOTS FROM 240-260 DEG
  BY LATE MORNING THROUGH THE AFTERNOON.

.PREV DISCUSSION...ISSUED 1100 PM EDT THU APR 18 2013

UPDATE...

THE LATEST OBSERVATIONS POINT TO THE FRONT MOVING THROUGH SE
MICHIGAN BEFORE SUNRISE WITH GUSTS IN THE 30 TO 40 MPH RANGE, AND
THEN JUST ALONG AND SHORTLY BEHIND THE WIND SHIFT. GUSTS ARE THEN
EXPECTED TO SETTLE DOWN AROUND 30 MPH UNTIL MID TO LATE FRIDAY
MORNING WHEN SURFACE HEATING BUILDS THE MIXED LAYER ENOUGH FOR
GUSTS TO INCREASE AGAIN TO ABOUT 45 MPH. FOR NOW, PLAN TO HANDLE
THE FRONTAL PASSAGE WITH SHORT FUSED STATEMENTS AND THEN ISSUE A
WIND ADVISORY OFF THE 4 AM PACKAGE FOR THE DAYTIME FRIDAY.

THE EVENING UPDATE WILL WORK THE LATEST PRECIPITATION TRENDS INTO
THE FORECAST AS THE FOCUS FOR THE HEAVIEST RAINFALL SHIFTS BACK
INTO THE TRI CITIES AND NORTHERN THUMB FOR THE OVERNIGHT HOURS.

PREV DISCUSSION...ISSUED 404 PM EDT THU APR 18 2013

SHORT TERM...THROUGH TONIGHT

MID LEVEL CIRCULATION WILL DEEPEN WITH TIME AS IT RAPIDLY EJECTS
NORTHEAST INTO THE UPPER MS VALLEY THROUGH TONIGHT.   THE
NORTHEASTWARD SPRAWLING HEIGHT FALL REGION WILL DRIVE THE SURFACE
LOW TO THE UPPER PENINSULA BY LATE TONIGHT...EFFECTIVELY SWEEPING
THE STRONG ATTENDANT COLD FRONT THROUGH SOUTHEAST MICHIGAN 07-11Z.
TREMENDOUS KINEMATIC FIELD REMAINS ANCHORED WITHIN THE DEEP
PRE-FRONTAL SOUTHWEST FLOW...CARRYING A SOLID 50-60 KNOT LOW LEVEL
JET CAPPED BY THE FAVORABLE EXIT REGION A 120 KNOT UPPER JET CORE.
THE EASTWARD PROPAGATION OF THIS ENTIRE FORCING FORCING FIELD WILL
PROMPT A RENEWED EXPANSION IN SHOWERS/THUNDERSTORMS FOR TONIGHT.

WING OF ENHANCED CONVERGENCE ELONGATED ALONG AND JUST SOUTH OF A
LEAD SURFACE WAVE...AND PERHAPS AIDED BY A SUBTLE GRAVITY WAVE
FEATURE...CURRENTLY RIPPLING THROUGH CENTRAL LOWER MI FACILITATING
THE EASTWARD PROPAGATION OF A THIN CONVECTIVE LINE AND TRAILING
RAGGED REGION OF SHOWERS ACROSS SE MICHIGAN THIS AFTERNOON.  THIS
PROCESS EFFECTIVELY DIMINISHING A MARGINALLY SUPPORTIVE LOW LEVEL
THERMODYNAMIC FIELD (MUCAPE 500-1000 J/KG)...LEAVING AN ENVIRONMENT
MORE SUPPORTIVE OF HEAVY RAIN/EMBEDDED THUNDER AS THE STRONG MASS
CONVERGENCE ON THE NOSE OF THE LOW LEVEL JET CONTINUES TO SUPPORT
PRECIPITATION DEVELOPMENT ALONG AN EXTENSIVE CORRIDOR STRETCHING
FROM SOUTHERN MI TO SOUTHERN IL/IN.  HOWEVER AS NOTED ALREADY...ANY
HEAVIER CELLS WILL CONTINUE TO POSE A HIGHER WIND GUST THREAT
/MAINLY ACROSS THE SOUTHEAST CORRIDOR/ GIVEN THE STRONG WIND FIELD
RESIDING JUST OFF THE SURFACE AND WHATEVER MINIMAL NOCTURNAL STABLE
LAYER ATTEMPTS TO EMERGE.

STRONGEST ASCENT WILL ALIGN DIRECTLY IN ADVANCE OF THE APPROACHING
FRONTAL ZONE...SWEEPING THROUGH SE MICHIGAN 06-12Z TONIGHT.  THE
PRESENCE OF A MOISTURE/THETA-E RICH ENVIRONMENT (PW TO 1.25") WILL
SUPPORT ONE FINAL BAND OF WIDESPREAD HEAVIER RAINFALL ACROSS THE
REGION DURING THIS TIME.  ADDITIONAL QPF IN THE INCH RANGE REMAINS
POSSIBLE...AND THE FLOOD WATCH WILL REMAIN INTACT THROUGH FRIDAY
MORNING TO CAPTURE ANY ADDITIONAL ADDITIVE RESPONSE THIS QPF PROVIDES.
THE PASSAGE OF THE FRONT ITSELF MAY PROVIDE A GOOD WIND RESPONSE
RIGHT AT DAYBREAK...WITH A PERIOD OF SOLID ISENTROPIC DESCENT
WORKING THE EXISTING STRONG WIND FIELD TOWARD THE SURFACE.

LONG TERM...FRIDAY THROUGH WEDNESDAY

A MODERATE WSW GRADIENT WRAPPING AROUND AN OCCLUDING CYCLONE
POSITIONED NEAR THE STRAITS WILL HAVE NO PROBLEM DRIVING SUSTAINED
25KT WINDS ACROSS THE CWA FOR THE BALANCE OF THE DAY ON FRIDAY. AS
HAS BEEN DISCUSSED OVER THE PAST SEVERAL FORECAST SHIFTS, THE
PRIMARY CONCERN CONTINUES TO BE UPPER-END WIND POTENTIAL. THE LATEST
GUIDANCE AND FORECAST THINKING OFFER LITTLE REASON TO CHANGE COURSE
FROM THE INHERITED FORECAST WHICH INDICATES AN AREAWIDE WIND
ADVISORY TYPE EVENT WITH GUSTS TO 45 MPH APPEARING LIKELY FOR MUCH
OF THE DAY ON FRIDAY, ESPECIALLY ACROSS THE NORTHWEST. STRONG
INITIAL SHOT OF CAA CHARACTERIZED BY H85 TEMPS FALLING 10+ DEGREES
IN THE FIRST 3 HOURS OF THE FORECAST PERIOD WILL BE SUFFICIENT TO
SUPPORT GUSTS TO 30+KTS EARLY ON BEFORE DIURNAL BOUNDARY LAYER
GROWTH ALLOWS FOR ADDITIONAL DOWNWARD MIXING OF THE HIGHER MOMENTUM
ENVIRONMENTAL WIND FIELD. CROSS-SECTIONS TAKEN THROUGH THE
POST-FRONTAL ENVIRONMENT INDICATE A STRONGLY UNSTABLE 0-1KM LAYER
PER RICHARDSON #S OF -1.5 TO -2.5 PERSISTING THROUGH THE DAY, WHICH
STILL SUPPORTS A DECENT LIKELIHOOD OF A WIND ADVISORY FOR PART OR
ALL OF THE CWA BEGINNING AROUND 15Z OR SLIGHTLY LATER FRIDAY MORNING.
HOWEVER, GIVEN THE SUBSTANTIAL CONVECTIVE COMPONENT THAT IS/WILL BE
CONTRIBUTING TO THE OVERALL SYSTEM EVOLUTION AND THE FACT THAT IT IS
STILL A 2ND PERIOD EVENT, STRONG PREFERENCE IS GIVEN TO ALLOWING THE
MID CREW ONE ADDITIONAL OPPORTUNITY TO EVALUATE POTENTIAL BEFORE
HEADLINE ISSUANCE. REGARDING ANY "HIGH WIND" HEADLINE POTENTIAL, NOT
PARTICULARLY IMPRESSED GIVEN THE LACK OF ANY REAL SUPPORT FROM THE
FILLING CYCLONE ASIDE FROM THE AFOREMENTIONED MIXED GRADIENT FLOW,
AND CONFIDENCE IS SIMPLY NOT THERE THAT CRITERIA IS ACHIEVABLE
BASED ON MIXING ALONE...WOULD REALLY PREFER TO SEE SOME COMPONENT OF
SYSTEM RELATIVE ISALLOBARIC FORCING, WHICH WILL NOT BE THERE WITH A
FILLING LOW. WILL ABUNDANT LOW-LEVEL MOISTURE AND DEEP MIXING WILL
SUPPORT WIDESPREAD STRATOCU AND SHOWERS IN THE WAKE OF THE FRONT,
WITH A POTENTIAL TRANSITION TO SNOW SHOWERS BY LATE FRIDAY AS COLD
AIR DEEPENS AND HEATING WANES.

BY SAT MORNING, H85 TEMPS ARE FORECAST TO DIP TO -12C IN THE
PRESENCE OF BROAD CYCLONIC FLOW AND A RENEWED DAYTIME HEATING
COMPONENT. THIS WILL CONTINUE TO SUPPORT PLENTY OF CLOUDS AND COOLER
TEMPERATURES AROUND 40. DEEP LAYER SUBSIDENCE WILL SPREAD INTO
SOUTHEAST MICHIGAN ON SATURDAY NIGHT, SUPPORTING A DECREASE IN CLOUD
COVER AND SURFACE GRADIENT WHICH SHOULD ALLOW LOWS TO RADIATE INTO
THE UPPER 20S/LOW 30S.

MARINE...

THE MODERATE TO STRONG SOUTHERLY OFFSHORE BREEZE WILL PERSIST INTO
THE OVERNIGHT PERIOD. INITIALLY THE OFFSHORE FETCH CAN BE EXPECTED
TO KEEP SIGNIFICANT WAVES AT A MINIMUM FOR NEARSHORE AREAS.
HOWEVER...A COLD FRONT CARRYING WIDESPREAD SHOWERS AND THUNDERSTORMS
WILL TRACK ACROSS THE WATERS LATE TONIGHT INTO EARLY FRIDAY MORNING.
IN ADDITION TO BRINGING THE POTENTIAL FOR BRIEF GUSTY WINDS TO 40
MPH AND ELEVATED WAVES IN AND NEAR THUNDERSTORMS...COLD AIR
SPREADING INTO THE AREA IN THE WAKE OF THIS FRONT WILL SUPPORT AN
EPISODE OF STRONG WSW GALES BEGINNING DURING THE PREDAWN HOURS
FRIDAY AND PEAKING ON FRIDAY AFTERNOON. ELEVATED WAVE CONDITIONS CAN
BE EXPECTED FOR ALL NEARSHORE ZONES DURING THIS TIME WITH
SIGNIFICANT WAVE HEIGHTS PEAKING NEAR 10 FEET ACROSS THE OPEN WATERS
OF CENTRAL LAKE HURON BY LATE FRIDAY. GALES WILL SUBSIDE BY EARLY
SATURDAY MORNING WITH WINDS THEN EXPECTED TO RAPIDLY DIMINISH DURING
THE DAY SATURDAY. RELATIVELY TRANQUIL CONDITIONS CAN THEN BE
EXPECTED ACROSS THE WATERS BY SATURDAY NIGHT AS HIGH PRESSURE BUILDS
INTO THE AREA.
