Damaging Wind in Michigan, June 11, 2015

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
702 PM EDT THU JUN 11 2015

.AVIATION...

STEADY INCREASE IN MID LEVEL MOISTURE AND INSTABILITY HEADING INTO
TONIGHT WILL MAINTAIN THE POSSIBILITY FOR THUNDERSTORM DEVELOPMENT
AT ALL TERMINALS.  HOWEVER LOW LEVEL EASTERLY FLOW STILL IN PLACE
NORTH OF A WARM FRONT WILL FAVOR A LIMITED COVERAGE/POTENTIAL
THROUGH AT LEAST THE FIRST HALF OF THE NIGHT.  GREATER POTENTIAL
INTO THE MORNING HOURS...PARTICULARLY ACROSS MBS/FNT...AS THE WARM
FRONT AND A SURFACE LOW LIFT INTO THE REGION.   THIS WILL SUPPORT A
PERIOD OF LOW MVFR/IFR AT THESE TERMINALS.  MOST LIKELY PERIOD FOR
THUNDERSTORMS IN METRO DETROIT ARRIVES EARLY FRIDAY AFTERNOON IN
ADVANCE OF A COLD FRONT.  EAST TO SOUTHEAST WIND THROUGH FRIDAY
MORNING...TRANSITIONING TO A PERIOD OF GUSTY PRE-FRONTAL SOUTHERLY
WIND AS FAR NORTH AS PTK.

FOR DTW...PROBABILITY FOR THUNDERSTORMS AT ANY POINT TONIGHT REMAINS
TOO LOW TO INCLUDE A SPECIFIC MENTION.  MID LEVEL INSTABILITY WILL
BE INCREASING WITH TIME...LEAVING THE DOOR OPEN FOR ISOLATED/
SCATTERED CELLS TO EMERGE AT ANY TIME BEFORE THE WARM FRONT EXITS TO
THE NORTH BY 10-12Z.  WIND SHIFT FROM EAST/SOUTHEAST TO SOUTHWEST
WITH THE FRONTAL PASSAGE...SW WINDS TURNING GUSTY BY MIDDAY.
GREATEST POTENTIAL FOR THUNDERSTORMS EARLY FRIDAY AFTERNOON.

//DTW THRESHOLD PROBABILITIES...

* LOW FOR THUNDERSTORMS THROUGH FRIDAY MORNING...MEDIUM FRIDAY
  AFTERNOON.

* LOW IN CEILINGS DROPPING BELOW 5000 FT THROUGH FRIDAY
  MORNING...MEDIUM FRIDAY AFTERNOON.

SHORT TERM... THIS EVENING AND TONIGHT

A REMNANT MID LEVEL CIRCULATION FROM EARLIER UPSTREAM CONVECTIVE
ACTIVITY ROLLED ACROSS THE NRN DETROIT SUBURBS THIS AFTERNOON. THIS
FEATURE LED TO THE DEVELOPMENT OF SCT SHOWERS ACROSS THE SRN HALF
OF THE FORECAST AREA. THIS WAVE ALONG WITH THE EASTERLY LOW LEVEL
FLOW OFF LAKE ERIE HAS SUPPRESSED THE SURFACE FRONT OVER NRN OHIO.
THE EASTERLY FLOW...AMPLE HIGH CLOUDS SHEARING OFF UPSTREAM
CONVECTION AND THE SCT SHOWERS HAVE HELD TEMPS IN THE UPPER 60S
AND LOW 70S OVER SE MI THIS AFTERNOON. MEANWHILE...WARM AND
UNSTABLE AIR RESIDES JUST SOUTH OF THIS FRONTAL BOUNDARY.

SHOWERS HAVE PERSISTED ACROSS SRN MI THIS AFTERNOON AS A RESULT OF
AN INCREASE IN MID LEVEL MOISTURE TRANSPORT...AIDED BY INCREASED MID
LEVEL SW FLOW AHEAD OF THE SHORT WAVE IMPULSE NOW LIFTING ACROSS SRN
WISCONSIN. THIS MID LEVEL MOISTURE TRANSPORT WILL SUSTAIN SOME
DEGREE OF SCATTERED SHOWERS INTO THE EARLY EVENING...WITH THE BEST
POTENTIAL FOR THUNDERSTORMS CONFINED SOUTH OF I-94 /CLOSER TO SOME
MODEST MID LEVEL INSTABILITY/. A STRONGER MID LEVEL WAVE NOW OVER
IOWA WILL LIFT INTO THE WRN GREAT LAKES OVERNIGHT. SOUTHERLY LOW-MID
LEVEL FLOW ACROSS THE NRN OHIO VALLEY/SRN LOWER MI WILL INCREASE
DURING THE NIGHT IN RESPONSE. THIS WILL FORCE THE SFC FRONT TO LIFT
NORTH INTO SRN MI AS A WARM FRONT WITH A SURFACE LOW TRACKING ACROSS
IOWA INTO NRN ILLINOIS. THIS WILL ALSO TRANSPORT A GOOD DEGREE OF
ELEVATED INSTABILITY INTO SE MI. 0-3KM MU CAPE IS FORECAST TO RISE
TOWARD 1500 J/KG IN THE 06Z TO 12Z TIME FRAME. STEEPENING MID LEVEL
LAPSE RATES AND GOOD CAPE DENSITY SHOWN ON MODEL SOUNDINGS WILL
SUPPORT A CHANCE OF STRONG/SEVERE STORMS DURING THE OVERNIGHT PERIOD
INTO EARLY FRI MORNING /LARGE HAIL AND LOCALIZED DAMAGING WIND GUSTS
BEING THE MAIN HAZARDS/.

COVERAGE OF CONVECTION IS ACTUALLY EXPECTED TO BECOME GREATEST
ACROSS THE NRN HALF OF THE FORECAST AREA DURING THE NIGHT. MID LEVEL
HEIGHT FALLS AND STRONG MID LEVEL FRONTAL FORCING WITHIN THE
ENTRANCE REGION OF AN UPPER JET WILL TARGET THE SAGINAW VALLEY WITH
THE GREATEST FORCING. PROPAGATION OF EXPECTED UPSTREAM CONVECTIVE
DEVELOPMENT TONIGHT DOES HOWEVER ADD SOME DEGREE OF UNCERTAINTY AS
TO WHERE IN SE MI THE HEAVIEST RAINS WILL OCCUR. GIVEN THE DEGREE OF
MOISTURE TRANSPORT INTO THE GREAT LAKES TONIGHT /PRECIP WATER
FORECAST TO EXCEED 1.8 INCHES/ THERE IS THE POTENTIAL FOR SOME
INTENSE RAINFALL RATES AND LOCALIZED FLOODING.

LONG TERM...

MID-LEVEL WAVE INTERACTION NOT UNFOLDING AS MODELED AS TWO UPPER
WAVES WHICH WERE FORECAST TO BECOME PHASED, REMAINED TWO LARGELY
DISTINCT ENTITIES THIS MORNING. THE RESULTANT SENSIBLE WX IMPACTS
WERE EVIDENT ON NATIONAL RADAR MOSAIC WHERE TWO SEPARATE RAIN
SHIELDS ARE TRANSITING THE WESTERN/NORTHERN GREAT LAKES AND THE
LOWER MISSOURI RIVER VALLEY. THE EXPECTATION NOW MUST BE FOR A
FLATTER OVERALL EVOLUTION FOR FRIDAY, AND THIS IS DEPICTED WELL ON
THE 12Z GUIDANCE. LAST NIGHT'S 00Z ARW APPEARS TO BE THE ONLY MEMBER
OF THE NWP SUITE THAT PICKED UP ON THIS WAVE SEPARATION AND IT
REMAINS THE PREFERRED GUIDANCE THROUGH FRIDAY.

AFOREMENTIONED UPPER AIR EVOLUTION WILL ALLOW STRONG DYNAMIC JET-
FRONT SUPPORT WITHIN THE RIGHT ENTRANCE REGION TO SAG FURTHER SOUTH
WITHIN, BRINGING A PERIOD OF STRONG DEEP LAYER FORCING TO THE
PORTIONS OF THE SAGINAW VALLEY AREA 9-15Z TONIGHT/EARLY FRI.
SIGNIFICANT COMPONENT OF LLJ WILL BE BOUNDARY PARALLEL RESULTING IN
ABUNDANT MOISTURE TRANSPORT GIVEN PWATS APPROACHING 2". STRONGEST
DEFORMATION IS PROGGED BY THE HIGH RES SUITE TO REMAIN LARGELY
CONFINED TO THE SAGINAW VALLEY AREA...PARTICULARLY NORTHERN FRINGES.
ORGANIZED DEFORMATION RAIN WILL RAPIDLY SHIFT EAST OF THE AREA 15-
18Z AS RIGHT ENTRANCE SUPPORT REORIENTS OVER QUEBEC. 1-2" IN
BAY/MIDLAND SHOULD BE EASILY ACHIEVABLE, PARTICULARLY WHEN
CONSIDERING THE PRESENCE OF MODESTLY UNSTABLE PARCELS ORIGINATING
WITHIN THE CORRIDOR OF STRONGER MID-LEVEL THETA-E TRANSPORT AND VERY
FAVORABLE WARM THERMODYNAMIC ENVIRONMENT THROUGH THE LOWEST 11KFT.

HIGH TEMPERATURES FOR FRIDAY WERE ALSO LOWERED AN AVERAGE OF 10
DEGREES ACROSS THE BOARD (-15 NORTHWEST/-5 SOUTHEAST) GIVEN
PERSISTENT NORTHEAST GRADIENT OFF OF LAKE HURON ACROSS THE NORTH
RESULTING FROM IMPEDED NORTHWARD PROGRESS OF THE FRONT. EXPECTATION
IS FOR SAGINAW VALLEY AND THUMB TO STRUGGLE INTO THE LOW 60S.
LOCALES FROM M59 SOUTH WILL REMAIN IN THE WARM SECTOR THROUGH MUCH
OF PEAK HEATING AND SHOULD MANAGE TO ECLIPSE 80F, ESPECIALLY SOUTH
OF 8 MILE.

A SHORTER RESIDENCE TIME OF THE INSTABILITY AXIS OVER SOUTHEAST
MICHIGAN IS ANTICIPATED AS A RESULT OF QUICKER FROPA. PRIMARY SEVERE
THREAT APPEARS TO BE FROM M59 SOUTH WITH THE GREATEST THREAT
FURTHEST SOUTH AND EAST. MOIST WARM SECTOR ENVIRONMENT WILL SUPPORT
MIXED LAYER CAPE VALUES OF 1000-1500 J/KG. LEAD SURFACE LOW RIPPLING
ALONG THE BAROCLINIC ZONE WILL SUPPORT LOCALLY ENHANCED 0-1KM STORM
RELATIVE HELICITY VALUES OF 250 OR SO IN THE PRESENCE OF 40KT 0-6KM
DEEP LAYER BULK SHEAR AND A LOWER LCL ENVIRONMENT. POTENTIAL FOR
SUPERCELLS CAPABLE OF GENERATING TORNADOES WILL EXIST, IN ADDITION
TO WIND/HAIL. STRONG MID-LEVEL FLOW OF 50 KTS ACROSS THE INTIATING
BOUNDARY WILL FAVOR SOME POTENTIAL FOR REAR INFLOW JETS/CONVECTIVE
AUGMENTATION OF ENVIRONMENTAL WINDS SUCH THAT AN EVOLUTION TOWARD
BOWING SEGMENTS SEEMS A REASONABLE EXPECTATION AS WELL.

IT SHOULD BE NOTED THAT WHILE PARAMETER SPACE WILL BE SUPPORTIVE OF
SUPERCELLS, THE PICTURE WHEN IT COMES TO CONVECTIVE INITIATION ON
FRIDAY REMAINS QUITE MUDDLED AND SUPERCELL POTENTIAL MAY VERY WELL
GO UNREALIZED, PARTICULARLY IF EARLY CONVECTION BECOMES TOO
WIDESPREAD WITHIN THE PREFRONTAL TROUGH, WHICH COULD SHORT CIRCUIT
AFTERNOON POTENTIAL ALTOGETHER.

FRONT WILL THEN ORIENT PARALLEL TO DEEP LAYER MEAN FLOW BY 21-00Z
ACROSS THE SOUTH, ENDING THE SEVERE THREAT FOR MOST OF THE AREA, BUT
POTENTIALLY SETTING UP A FEW HOURS OF POTENTIAL TRAINING SOUTH OF I-
94. THE FORECAST REMAINS RATHER FLUID, BUT SPC DAY 2 MENTION OF
TORNADIC THREAT IN ADDITION TO WIND/HAIL REMAINS AN ACCURATE
DEPICTION OF CONFIDENCE ATTM. HIGH PRESSURE BUILDS IN SATURDAY INTO
LATE SATUDAY NIGHT.

MONDAY THROUGH FRIDAY.
THE FRONT THAT TRACKS INTO MICHIGAN SUNDAY WILL GAIN SOME MOMENTUM
OVERNIGHT INTO EARLY MONDAY MORNING. RAIN IS LIKELY THROUGH ABOUT
MID-DAY MONDAY WITH RAIN TAPERING OFF TO SHOWERS AND THUNDERSTORMS
FOR THE AFTERNOON. A QUICK SHOT OF HIGH PRESSURE TRIES TO IMPROVE
CONDITIONS FOR TUESDAY...BUT SOUTHERN COUNTIES MAY BE LESS LIKELY TO
BENEFIT AS INSTABILITY LINGERS. CHANCES FOR SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO PERSIST THROUGH FRIDAY.

MARINE...

LIGHT WINDS WILL BECOME NORTHEASTERLY LATE TONIGHT AND REMAIN SO
THROUGH FRIDAY. WINDS WILL NOT BE PARTICULARLY GUSTY BUT FUNNELING
INTO SAGINAW BAY WILL SUPPORT SUSTAINED WINDS OF 20 TO 25 KNOTS.
SMALL CRAFT ADVISORIES HAVE THEREFORE BEEN ISSUED FOR THE BAY.
THUNDERSTORMS...POSSIBLY SEVERE...WILL ALSO BE POSSIBLE ACROSS THE
WATERS...MAINLY FROM PORT SANILAC SOUTH. LIGHT WINDS WILL BUILD IN
WITH HIGH PRESSURE SATURDAY INTO SATURDAY NIGHT BEFORE THUNDERSTORM
CHANCES RETURN SUNDAY.
