AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
106 PM EDT FRI JUL 19 2013
.AVIATION...
//DISCUSSION...
ALTHOUGH THE COLD FRONT IS STILL BACK ACROSS WRN UPPER MI...AMPLE
DAYTIME DESTABILIZATION WITHIN SOME MOISTURE CONVERGENCE AHEAD OF
THE FRONT WILL LEAD TO INCREASING CHANCES FOR THUNDERSTORM
DEVELOPMENT ACROSS THE AREA THIS AFTERNOON AND EVENING. GIVEN THE
POTENTIAL INSTABILITY...SOME OF THESE STORMS MAY PRODUCE LOCALLY
HIGH WINDS. THE ACTUAL SFC COLD FRONT WILL NOT TRACK ACROSS SE MI
UNTIL TONIGHT. ADDITIONAL STRONG TO SEVERE THUNDERSTORMS ARE
POSSIBLE ALONG THIS COLD FRONT.
FOR DTW...THE GUSTY SOUTHWEST WINDS SHOULD PERSIST INTO THE EARLY
EVENING BARRING ANY EARLY ONSET TO CONVECTION. THE COLD FRONT WILL
SLOWLY PUSH ACROSS METRO DETROIT BETWEEN 09Z AND 12Z SATURDAY. THERE
IS CERTAINLY THE POSSIBILITY OF STRONG TO SEVERE STORMS IN THE
VICINITY OF THIS COLD FRONT AND WORTHY OF AT LEAST A PROB30 GROUP AT
THIS TIME.
//DTW THRESHOLD THREATS...
* LOW CONFIDENCE IN TIMING OF CEILING HEIGHTS BELOW 5000 FT THIS
AFTERNOON.
* HIGH CONFIDENCE OF THUNDERSTORMS IN VICINITY BY 21Z.

.PREV DISCUSSION...ISSUED 1043 AM EDT FRI JUL 19 2013
UPDATE...
MORNING TEMPS HAVE ALREADY SOARED INTO THE MID TO UPPER 80S UNDER
GUSTY SOUTHWEST WINDS. THERMAL ADVECTION UNDER THIS SW FLOW IN
ADVANCE OF THE SFC COLD FRONT WILL BOOST AFTERNOON TEMPS INTO THE
LOW TO MID 90S. THIS SUPPORTS A SLIGHT INCREASE IN FCST HIGHS THIS
AFTERNOON. THE EXCEPTION WILL BE ACROSS THE TRI CITIES WHERE AN
EARLIER ARRIVAL OF CONVECTION SHOULD LIMIT AFTERNOON TEMPS. THE
TEMPS COUPLED WITH THE LOW 70S SFC DEWPOINTS WILL LEAD TO ANOTHER
AFTERNOON WITH HEAT INDICES OF 100 TO 105 DEGREES.
THE REGION OF CONVECTION NOW EXTENDING FROM NORTHERN LAKE MICHIGAN
INTO NORTHERN LAKE HURON IS OCCURRING WITHIN A MID LEVEL MOISTURE
PLUME IN ADVANCE OF THE ACTUAL SFC COLD. THIS MOISTURE PLUME WILL
TRAVERSE SE MI THIS AFTERNOON. IN ADDITION...A REGION OF ENHANCED
LOW LEVEL CONVERGENCE HAS DEVELOPED AHEAD OF THIS CONVECTION WHICH
HAS ALREADY IGNITED CONVECTION OVER CENTRAL MI. THIS CONVERGENCE
IS LIKELY TO SUSTAIN ITSELF ALLOWING CONVECTION TO WORK INTO THE
SAGINAW VALLEY BY EARLY AFTERNOON. THE 12Z DTX SOUNDING AND RECENT
MODEL SOUNDINGS CONTINUE TO SUGGEST 0-1KM ML CAPE REACHING 1800 TO
2500 J/KG DURING THE AFTERNOON AND EVENING. MID LEVEL HEIGHT FALLS
AND ENTRANCE REGION UPPER JET DYNAMICS WILL OVERSPREAD SRN MI
DURING THE COURSE OF THE AFTERNOON AND EVENING...SUGGESTING
NUMEROUS TO WIDESPREAD COVERAGE OF CONVECTION. INCREASING MID
LEVEL WIND FIELDS DURING THE AFTERNOON/EVENING COMBINED WITH THE
MODERATE INSTABILITY WILL SUPPORT SOME SEVERE STORMS TODAY. THERE
WILL BE A WEAK MID LEVEL CAP OVER SE MI AND MID LEVEL LAPSE RATES
ARE NOT ALL THAT STEEP. THUS WHILE COVERAGE OF CONVECTION MAY BE
RATHER WIDESPREAD...STRONG TO SEVERE STORMS MAY BE MORE DISCRETE.
DAMAGING WIND GUSTS REMAIN THE MORE PROBABLE SEVERE WEATHER
THREAT. REGENERATIVE CONVECTION MAY HOWEVER CAUSE SOME LOCALIZED
FLOODING AS WELL.
PREV DISCUSSION...ISSUED 403 AM EDT FRI JUL 19 2013
SHORT TERM...TODAY AND TONIGHT
AN UPPER LEVEL TROUGH WILL DIG THROUGH THE UPPER PLAINS THIS MORNING
IMPINGING UPON THE NORTHERN GREAT LAKES DURING THE AFTERNOON HOURS.
ANTICYCLONIC CURVATURE FROM A PRECEDING UPPER LEVEL JET CORE
DIRECTLY NORTH OF LAKE HURON WILL KEEP ENOUGH OF A SHORTWAVE RIDGING
COMPONENT IN PLAY TO SLOW THE SOUTH/EAST PROGRESSION OF THE SURFACE
COLD FRONT. IN FACT...MODEL INDICATIONS ARE THE SURFACE COLD FRONT
WILL NOT CLEAR THE KGLR/KTVC/KMBL LINE UNTIL 00Z THIS EVENING. BY 6Z
TONIGHT...THE TRAILING JET STREAK AND ASSOCIATED RIGHT ENTRANCE
REGION DYNAMICS WILL SNAP DIRECTLY INTO PLACE OVER THE NORTHERN
1/3RD OF THE LOWER PENINSULA. THE 1000-500MB HEIGHT RISES WILL GAIN
A FOOTHOLD...ACCELERATING THE PASSAGE OF THE SFC COLD FRONT THE
LATTER HALF OF THE NIGHT.
PERSISTENCE WILL AGAIN BE THE OPERATIVE WORD THIS MORNING WITH
RECOGNIZABLE CAPPING IN THE 2500-5000 FT AGL LAYER. THIS SHOULD
CAUSE THE WEATHER TO BE QUIET EARLY ACROSS ALL OF SOUTHEASTERN
MICHIGAN. AS SEEN IN RECENT DAYS...TEMPERATURES WILL REBOUND QUICKLY
PUSHING 90 DEGREES BY NOON AREAWIDE. CLOUDS SHOULD BE FAIRLY LEAN
EARLY WITH CLEAN IR IMAGERY UPSTREAM THIS MORNING. THIS SETS THE
STAGE FOR ANOTHER HOT AND HUMID DAY. THERE IS A CHALLENGE IN HOW TO
HANDLE THE HEADLINES...GIVEN FORECASTED HEAT INDICES THAT ARE
NOTABLY BELOW THE 105 DEGREE THRESHOLD. IN FACT...SOME AREAS ARE
HARD PRESSED TO REACH THE 100 DEGREE MARK. HOWEVER...WILL MAINTAIN
THE EXCESSIVE HEAT WARNING OUT OF RESPECT FOR FORECAST CONTINUITY
AND THE POTENTIAL FOR SOME UNACCOUNTED COMPRESSIONAL WARMING OUT
AHEAD OF THE APPROACHING FRONTAL BOUNDARY. THIS DOES HAVE POTENTIAL
IF CONDITIONS PROVE TO BE DRIER THAN ANTICIPATED DURING THE LATE
AFTERNOON HOURS. AGAIN...A DIFFICULT PREDICAMENT.
MODEL DATA IS ADVERTISING THE THUNDERSTORM POTENTIAL WILL INCREASE
FOR THE AFTERNOON HOURS AS A PREFRONTAL BAND OF ENHANCED
DEFORMATION/VORTICITY SLIDES TOWARD THE CWA. THIS FORCING IS
EXPECTED TO ORGANIZE EARLY THIS MORNING IN VICINITY OF NW WI IN THE
TRAILING OR ENTRANCE REGION OF A 850/700MB MIDLEVEL JETLET OR
ZONALLY ORIENTATED LOW LEVEL JET AXIS. CONFIDENCE HAS INCREASED IN
THIS FORCING AS THUNDERSTORMS ARE NOW INITIATING OVER NW WISCONSIN
AS OF 6Z. NWP FORECASTS THUNDERSTORMS FILLING IN ALONG THIS
VORTICITY/DEFORMATION BAND FROM THE NORTHERN LAKE SUPERIOR SHORELINE
SOUTHWEST TO FAR NE NEBRASKA BY 11Z. THIS LINE OF SHOWERS AND
THUNDERSTORMS IS EXPECTED TO PUSH EASTWARD BRINGING THE
AFOREMENTIONED INCREASE IN THUNDERSTORM POTENTIAL BY 17Z MIDLAND/BAY
COUNTIES...FLINT BY 19Z...DETROIT BY 21Z. THIS WILL BE IN TIME TO
ACT UPON OR USE A VERY UNSTABLE THERMODYNAMIC PROFILE...MLCAPES IN
EXCESS OF 2000 J/KG.
CONVECTION THIS AFTERNOON IS EXPECTED TO BECOME
PREFRONTAL...OUTRUNNING ANY SIGNIFICANT INCREASE IN THE KINEMATIC
FIELD. THIS WILL LIMIT 0-6KM BULK SHEAR TO 20-25 KNOTS WHICH IS
CITED IN THE LATEST SWODY1 AND HAS SUPPORT FROM 19.00Z NAM AND 19.06
RUC PLAN VIEWS. CONVECTION IS EXPECTED TO ORGANIZE AS
MULTI-CELLS...FAVORING LINE SEGMENTS TO SOME DYNAMIC BOW STRUCTURES
OWING FROM THE AFOREMENTIONED BULK SHEAR VALUES AND A DEEP
UNIDIRECTIONAL WIND PROFILE. THE LACK OF AVAILABILITY TO THE GREATER
WIND MAGNITUDES HERE IN SOUTHEASTERN MICHIGAN LIMITS THE FORECASTING
OF SUPERCELLS. THEREFORE...THE WIDESPREAD SEVERE THREAT TODAY IS
EXPECTED TO BE DAMAGING WIND GUSTS. IT IS WORTH NOTING...THE NEAR
SURFACE SHEAR IS SOMETHING THAT NEEDS MENTIONING AS 0-.5 KM BULK
SHEAR VALUES ARE ON THE ORDER OF 20 KNOTS...WITH 0-1 KM HELICITY
VALUES BETWEEN 150-200 M2/S2. THESE VALUES FALL MARGINALLY INTO THE
PARAMETER SPACE SUPPORTIVE OF TORNADOGENESIS AND SWODY1 OUTLINES A
5% TORNADO PROB FOR MUCH OF THE CWA. THIS POTENTIAL WILL
PARTICULARLY NEED TO BE MONITORED WITH CELL MERGERS AND
CELL-BOUNDARY INTERACTIONS. FROM THE VANTAGE POINT THIS MORNING THE
BEST TIME PERIOD FOR SEVERE WEATHER WILL COME BETWEEN 18-03Z.
MODELS SHOW THE POTENTIAL FOR A SECOND LINE OF SHOWERS AND
THUNDERSTORMS SLIDING THROUGH THE CWA BETWEEN 01-09Z TONIGHT. THIS
POTENTIAL/FORCING MAY ARISE AS SOME INCREASED INSTABILITY
ADVECTS/RETURNS BACK INTO THE REGION IN TOW OF EARLIER CONVECTION
BUT IN ADVANCE OF THE APPROACHING COLD FRONT. CONFIDENCE ON HOW THIS
WILL UNFOLD IS MUCH LOWER.
LOWS TONIGHT WILL AGAIN BE MILD...MIDDLE 70S SOUTH TO THE UPPER 60S
NORTH.
LONG TERM...SATURDAY THROUGH THURSDAY
SOUTHERN EXTENSION OF THE LOWER HEIGHT FIELD EMANATING FROM THE
STRONG SHORTWAVE PIVOTING THROUGH THE MEAN HUDSON BAY TROUGH ACROSS
SOUTHERN ONTARIO WILL WORK ACROSS THE SOUTHEAST MICHIGAN OVER THE
UPCOMING WEEKEND. THIS IN COMBINATION WITH INCREASING LOW LEVEL
ANTICYCLONIC FLOW WILL PROVIDE A PROGRESSIVELY COOLER AND DRIER
ENVIRONMENT THROUGH THIS TIME. LEAD FRONTAL STRUCTURE WILL TAKE
SOME TIME TO EXIT THE REGION ON SATURDAY AS THE BOUNDARY BECOMES
INCREASINGLY PARALLEL TO THE MEAN FLOW...LEAVING THE INITIAL STAGES
OF THE COLD AIR ADVECTIVE PROCESS LAGGING. THIS WILL EFFECTIVELY
ALLOW THE STRONG DIABATIC HEATING INTO A WELL MIXED PROFILE TO WORK
TEMPERATURES BACK INTO THE MIDDLE AND UPPER 80S ACROSS ALL BUT
NORTHERN SECTIONS. THIS IN CONJUNCTION WITH THE FALLING HEIGHTS/
COOLING MID LEVELS WILL YIELD A STEEP LAPSE RATE ENVIRONMENT.
DIMINISHING MOISTURE QUALITY WILL PROVIDE SOME QUESTION TO THE
CONVECTIVE POTENTIAL. HOWEVER MODELS ARE HINTING AT AN ILL-DEFINED
SHORTWAVE OF NORTHWEST PACIFIC ORIGIN ARRIVING COINCIDENT WITH THE
HEATING CYCLE. ASSUMING SOME DEGREE OF LOW LEVEL CONVERGENCE
REMAINS PREVALENT ALONG THE FRONTAL SLOPE...THIS WILL SUPPORT AT
LEAST A LOW END CHANCE MENTION THROUGH THE EARLY PART OF THE DAY
/MAINLY SOUTH/.
A MORE CONCERTED AIRMASS ADJUSTMENT WILL COMMENCE BY SATURDAY
EVENING AS LOW LEVEL WINDS VEER TO NORTHERLY. THIS WILL BRING
DEWPOINTS MORE COMFORTABLY BACK INTO THE 50S. HIGH PRESSURE
WORKING THROUGH THE REGION WILL PROVIDE BENIGN CONDITIONS ON
SUNDAY. 850 MB TEMPERATURES BOTTOM OUT IN THE LOWER TEENS DURING
THIS TIME...SUPPORTING HIGHS IN THE 70S.
LOWER AMPLITUDE WEST-NORTHWEST MID LEVEL FLOW WILL DICTATE CONDITIONS
HEADING INTO THE EARLY AND MID WEEK PERIOD. THE EXTENSIVE WEST TO
EAST ELONGATED UPPER RIDGE WILL HOLD FIRMLY TO THE SOUTH UNDER THIS
PATTERN...RETAINING A MORE SEASONABLE LATE JULY TEMPERATURE REGIME.
GRADUAL MODULATION OF THE ENVIRONMENT IN THE WAKE OF THE DEPARTING
LOW LEVEL ANTICYCLONE WILL EASE TEMPERATURES BACK INTO THE 80S
THROUGH TUESDAY. PRECIPITATION CHANCES THROUGH THIS PERIOD REMAIN
QUITE ILL-DEFINED...OWING TO CONSIDERABLE DIFFERENCES YET IN
HANDLING BOTH THE PLACEMENT AND TIMING OF SHORTWAVE ENERGY EJECTING
ACROSS THE NORTHERN CONUS.
MARINE...
A COLD FRONT WILL MARCH SOUTHWARD ACROSS THE GREAT LAKES REGION
TODAY. IN RESPONSE...SOUTHWEST WINDS WILL SHOW A GRADUAL
INCREASE..TOPPING OUT AROUND 20 KNOTS THIS AFTERNOON. SIGNIFICANT
WAVE HEIGHTS WILL BUILD TO AROUND 3 FEET ACCORDINGLY...WITH HEIGHTS
OF 4 TO 5 FEET POSSIBLE ACROSS CENTRAL LAKE HURON. A FEW ROUNDS OF
THUNDERSTORMS CAN BE EXPECTED...WITH THE BEST CHANCE OF SEVERE
TOMORROW AFTERNOON AND EVENING. HIGH PRESSURE WILL BUILD IN DURING
THE WEEKEND RESULTING IN A RETURN TO MORE TRANQUIL CONDITIONS.
