NWS Detroit, MI wrote its last area forecast discussion before the first event at Aug 1, 12:01 AM EST, 2 hours 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 101 AM EDT MON AUG 1 2011 .AVIATION... //DISCUSSION... A WEAK SURFACE PRESSURE TROUGH WILL CONTINUE TO SETTLE SOUTH ACROSS SOUTHEAST MICHIGAN OVERNIGHT. AN ISOLATED SHOWER OR STORM REMAINS POSSIBLE TONIGHT ACROSS ALL OF SOUTHEAST MICHIGAN AND EVEN INTO THE DAY MONDAY AT THE DETROIT TERMINALS. OTHERWISE...CLOUDS BELOW 12KFT WILL BE RATHER SCARCE AND WINDS WILL REMAIN LIGHT. //DTW THRESHOLD THREATS... * LOW CONFIDENCE FOR AN ISOLATED SHOWER OR THUNDERSTORM AFTER 4 AM TONIGHT AND AGAIN MONDAY. && .PREV DISCUSSION...ISSUED 838 PM EDT SUN JUL 31 2011 UPDATE... SCATTERED CONVECTION OVER WISCONSIN...LAKE MICHIGAN...AND NOW FAR WESTERN LOWER MICHIGAN INITIATED ALONG A NEAR SURFACE CONVERGENCE ZONE IN A REGION OF RESPECTABLE MIXED LAYER INSTABILITY. ELEVATED LEVELS OF BOUNDARY LAYER MOISTURE HAVE POOLED ON THE LEEWARD SIDE OF THE CONVERGENCE ZONE AND NUMERICAL GUIDANCE SUPPORTS MAINTAINING AND ADVECTING APPRECIABLE / ~1500 J/KG / SLIGHTLY ELEVATED /925-850MB LAYER BASED/ CONVECTIVE POTENTIAL TONIGHT ACROSS LOWER MICHIGAN. LOCAL HIRES SOLUTIONS ALSO SUPPORT INCREASING FLOW AROUND 925MB...SIGNIFYING THE ESTABLISHMENT OF A MODEST INVERSION WIND MAX. THERE WILL BE A SLIGHT INCREASE IN CONVERGENCE AT THE BASE OF THE REMNANT DIURNAL BOUNDARY LAYER ALONG WITH SOME FURTHER DESTABILIZATION VIA NOCTURNAL COOLING AT THE TOP OF THE MOISTURE RIBBON. THESE FACTORS SHOULD ESTABLISH FAVORABLE CONDITIONS FOR ADDITIONAL WIDELY SCATTERED ILL-ORGANIZED CONVECTION TO DEVELOP OVER WESTERN LOWER MICHIGAN AND CONTINUE TO PERCOLATE THROUGH THE NIGHT ACROSS THE REST OF THE SOUTHERN LOWER MICHIGAN. PREV DISCUSSION...ISSUED 323 PM EDT SUN JUL 31 2011 SHORT TERM...TONIGHT ANOTHER HOT...BUT DRY DAY (THROUGH 3PM) AS TEMPERATURES HAVE OR WILL TOP OUT IN THE LOWER 90S/AROUND 90 DEGREES WITH LIGHT WESTERLY FLOW AND MOSTLY SUNNY SKIES. SURFACE DEW POINTS REMAIN STUCK IN THE 60S (OUTSIDE OF THE NORTHERN THUMB REGION)...WITH MIXED LAYER CAPES BELOW 2000 J/KG...AS OF 18Z. A SURFACE TROUGH ARRIVING THIS EVENING MAY BE ABLE TO TRIGGER ISOLATED TO LOW SCATTERED ACTIVITY...BUT LOSS OF DIURNAL HEATING WILL WORK AGAINST THE TROUGH AS THE NIGHT WEARS ON...WITH THE 850-700 MB THETA-E RIDGE AXIS MOVING THROUGH SOUTHEAST MICHIGAN REMAINING FAIRLY DIFFUSE. CERTAINLY WORTHY OF SLIGHT/LOW CHANCE POPS NONE-THE-LESS WITH THE MODEST HEIGHT FALLS/MID LEVEL COOLING COMING IN. WITH THE FAVORABLE LATE DAY/EARLY EVENING TIMING ACROSS THE NORTH THIRD OF THE CWA...MODERATE INSTABILITY AND ADEQUATE 0-6 KM BULK SHEAR/DOWNDRAFT CAPE...AN ISOLATED SEVERE THREAT WILL EXIST. DID NOT SEE MUCH OF A NEED TO ADJUST INHERITED MINS...WHICH ARE IN LINE WITH LATEST GUIDANCE. LONG TERM...MONDAY INTO NEXT WEEKEND SOUTHERN EXTENSION OF THE MID LEVEL HEIGHT FALLS ASSOCIATED WITH A MID TROPOSPHERIC PV ANOMALY CURRENTLY SEEN PIVOTING ACROSS HUDSON BAY WILL SETTLE INTO THE GREAT LAKES OVER THE NEXT 24 HOURS. THIS WILL EFFECTIVELY EASE A WEAK COLD FRONT SOUTHWARD AND THROUGH SOUTHEAST MICHIGAN ON MONDAY. THE DEGREE OF FRONTAL CONVERGENCE WILL BE ON THE WEAKER SIDE. HOWEVER...THE BACKGROUND THERMODYNAMIC ENVIRONMENT WILL BECOME INCREASINGLY FAVORABLE FOR CELL GROWTH SHOULD CONVECTION MANAGE TO INITIATE ALONG THIS BOUNDARY BEFORE IT SHIFTS SOUTH OF THE AREA...AS A LOWERING HEIGHT FIELD ESTABLISHES MUCH STEEPER LAPSE RATES WITH COOLING COMMENCING IN THE MID LEVELS. MODEL SOUNDING DATA CONTINUE TO SUGGEST MLCAPE VALUES NEAR 2000 J/KG...ESPECIALLY SOUTH OF THE I-69 CORRIDOR. THIS SUPPORTS A LOW END POP THROUGH THE DAY. ANY STORM THAT DEVELOPS WOULD CARRY A RISK OF STRONGER WIND GUSTS WITH AN INCREASING DCAPE PROFILE/INVERTED-V STRUCTURE AND JUST ENOUGH DEEP LAYER SHEAR TO SUSTAIN AN ORGANIZED UPDRAFT. A WELL MIXED WESTERLY FLOW WITH 850 MB TEMPERATURES HOLDING IN THE UPPER TEENS WILL ALLOW HIGHS TO AGAIN MAKE A RUN TOWARD 90/LOWER 90S OUTSIDE OF THE THUMB. ANY POST-FRONTAL COOLING/DRYING WILL BE BRIEF AND RATHER MINOR INTO MONDAY NIGHT...WITH DEVELOPING LOW LEVEL SOUTHWEST FLOW ALLOWING A WARM FRONT AND INITIAL THETA-E GRADIENT TO SHIFT BACK THROUGH THE REGION ON TUESDAY. WHILE THE UPWARD VERTICAL MOTION ALONG THIS FRONTAL ZONE WILL NOT BE OVERLY STRONG...THE AIRMASS ADJUSTMENT ARRIVING IN CONJUNCTION WITH INCREASING DAYTIME DESTABILIZATION MAY PROMOTE SCATTERED CONVECTIVE DEVELOPMENT THROUGHOUT THE DAY. IN ADDITION...A NOCTURNALLY DRIVEN CONVECTIVE COMPLEX WILL LIKELY ORGANIZE MONDAY NIGHT OVER THE UPPER MS VALLEY AT THE INFLECTION POINT OF STRONG LOW LEVEL JET DYNAMICS...MOISTURE ADVECTION AND INCREASING MID LEVEL ASCENT WITH THE PASSAGE OF A STRONGER SHORTWAVE. THIS COMPLEX WILL HAVE BOTH THE THERMODYNAMIC/KINEMATIC SUPPORT AND MEAN TRAJECTORY FOR POSSIBLE UPSCALE GROWTH INTO THE GREAT LAKES ON TUESDAY...ARRIVING INTO SOUTHEAST MICHIGAN LATE TUESDAY INTO TUESDAY NIGHT. THUNDERSTORMS DEVELOPING BOTH IN ADVANCE OF AND CONTAINED WITHIN ANY COMPLEX WILL CONTAIN A SEVERE WIND/HAIL THREAT WITH 0-6 KM BULK SHEAR CLIMBING OVER 30 KNOTS AND AT LEAST MODERATE INSTABILITY IN PLACE. ASSUMING EARLY DAY CLOUDS/PRECIPITATION ARE LESS PREVALENT...HIGHS WILL AGAIN PUSH TOWARD THE 88 TO 92F RANGE. DEEPER MOISTURE/INSTABILITY AXIS WILL SWEEP EAST BY WEDNESDAY MORNING AS A COLD FRONT EXITS THE REGION. LINGERING BOUNDARY LAYER MOISTURE WILL PROMOTE A GENEROUS DIURNAL CU FIELD AND PERHAPS A COUPLE OF SHOWERS UNDER WEAKLY CYCLONIC FLOW...WITH THE THERMAL ADVECTIVE PROCESS NUDGING HIGHS DOWN A NOTCH INTO THE LOW-MID 80S. LITTLE AIRMASS CHANGE NOTED FOR THURSDAY AS BUILDING HIGH PRESSURE PROVIDES A HIGHER DEGREE OF DIABATIC HEATING. SOUTHEAST MICHIGAN WILL REMAIN POSITIONED ON THE NORTHERN PERIPHERY OF THE WEST TO EAST ELONGATED UPPER RIDGE FRIDAY INTO THE UPCOMING WEEKEND. THIS WILL LEAVE THE REGION ON THE EDGE OF THE CAP AND THE MORE DEFINED INSTABILITY GRADIENT. ILL-DEFINED SHORTWAVE ENERGY...PERHAPS CONVECTIVELY ENHANCED...WILL ATTEMPT TO SLIDE EASTWARD ALONG THIS AXIS AND WILL PROVIDE AT LEAST A LOW END OPPORTUNITY FRIDAY. AIRMASS WILL UNDERGO SLIGHT MODERATION AS UPPER HEIGHTS/THICKNESSES EASE UPWARD...BUT GENERALLY LOOKING AT READINGS JUST A TICK ABOVE EARLY AUGUST NORMS /HIGHS MIDDLE-UPPER 80S...LOWS LOWER-MIDDLE 60S/. CLIMATE... WE WILL BE FINISHING JULY THE WAY WE STARTED...HOT. SO HOT IN FACT...JULY 2011 WILL GO DOWN AS THE WARMEST ON RECORD AT DETROIT...AS THE MONTHLY AVERAGE TEMPERATURE WILL LIKELY CHECK IN AT 79.3 DEGREES...BEATING THE 79.0 DEGREES SET IN 1955 AND 1921. 20 DAYS THE HIGH TEMPERATURE REACHED OR SURPASSED 89 DEGREES...TIED FOR THE HIGHEST TOTAL (1955). ASSUMING NO RAIN ARRIVES BEFORE MIDNIGHT...DETROIT WILL ALSO FINISH AS THE SECOND WETTEST JULY ON RECORD WITH A TOTAL OF 7.66 INCHES. THE RECORD IS 8.76 INCHES SET IN 1878. MARINE... THE NEXT SEVERAL DAYS WILL FEATURE LIGHT WINDS AND SMALL WAVES. THE ONLY POSSIBLE DISRUPTION TO THE FAVORABLE BOATING CONDITIONS WILL BE THE POSSIBILITY OF THUNDERSTORMS TONIGHT AND ESPECIALLY ON TUESDAY AS LOW PRESSURE SYSTEM TRACKS THROUGH THE CENTRAL GREAT LAKES REGION. && .DTX WATCHES/WARNINGS/ADVISORIES...
