The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Detroit, MI wrote its last area forecast discussion before the first event at Sep 5, 12:11 PM EST, 2 hours 29 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 111 PM EDT FRI SEP 5 2014 .AVIATION... //DISCUSSION... BUILDING INSTABILITY THIS AFTERNOON AND THE APPROACH OF A COLD FRONT WILL SET THE STAGE FOR STRONG THUNDERSTORMS. WHILE THE ACTUAL COLD FRONT WILL NOT PASS ACROSS SE MI UNTIL 20-00Z...CONVERGENCE IN THE PREFRONTAL ENVIRONMENT LOOKS TO SET THE STAGE FOR THUNDERSTORM DEVELOPMENT JUST PRIOR TO FROPA. THE LATEST RADAR TRENDS ARE ALREADY SHOWING DEVELOPMENT TAKING HOLD TO THE NORTHWEST OF MBS. A LULL IN ACTIVITY IS EXPECTED AFTER 00Z WITH THE PASSAGE OF THE FRONT...THEN A REGION OF POST FRONTAL RAIN SHOWERS IS FORECAST TO DEVELOP OVERNIGHT. THE DEEPENING OF A POST FRONTAL INVERSION WITH SOME RESIDUAL MOISTURE SHOULD RESULT IN SOME MVFR OR IFR STRATUS PERSISTING INTO DAYBREAK SAT. FOR DTW...CONFIDENCE IS GROWING THAT THE METRO AIRSPACE WILL BE IMPACTED BY SOME STRONG STORMS TODAY. RECENT MODEL SOLUTIONS AND TIMING OF THE LOW LEVEL FORCING SUGGEST THE MOST PROBABLE TIME PERIOD OF CONVECTION WILL BE BETWEEN 20Z AND 23Z. //DTW THRESHOLD THREATS... * HIGH CONFIDENCE THUNDERSTORMS WILL IMPACT PORTIONS OF THE METRO AIRSPACE THIS AFTERNOON. * MEDIUM CONFIDENCE CEILINGS BELOW 5000 FT WILL DEVELOP OVERNIGHT. && .PREV DISCUSSION...ISSUED 1102 AM EDT FRI SEP 5 2014 UPDATE... THE 12Z DTX SOUNDING DID SHOW A FORMIDABLE CAPPING INVERSION NEAR 700MB. STEEP MID LEVEL LAPSE RATES ABOVE THIS CAPPING INVERSION RESULT IN GOOD CAPE DENSITY. WHILE THE SURFACE OUTFLOW FROM THE PROLONGED CONVECTION OVER NORTHERN LOWER MI THIS MORNING WILL BE HELD NORTH BY THE SOUTHWEST FLOW OVER SRN MI...THE ADDED MOISTURE HAS LED TO THE DEVELOPMENT OF A STRATUS DECK NOW COVERING MUCH OF CNRTL LOWER. DAYTIME MIXING WILL ERODE SOME OF THIS...HOWEVER CURRENT SATELLITE TRENDS SUGGEST THE POTENTIAL FOR A HEALTHY STRATO CU FIELD EXPANDING ACROSS THE SAGINAW VALLEY AND NORTHERN THUMB TODAY. THESE CLOUDS WILL OF COURSE LIMIT DAYTIME HEATING AND POTENTIAL INSTABILITY. FARTHER SOUTH...DAYTIME INSULATION HAS BEEN OFF TO A GOOD START AS TEMPS ARE ALREADY INTO THE LOWER 80S OVER MOST OF METRO DETROIT. LOW LEVEL MOISTURE ADVECTION WITHIN THE SW FLOW SHOULD SUSTAIN LOWER 70 SFC DEWPOINTS. THE MODIFIED 12Z DTX SOUNDING FOR LOWER 90S OVER LOWER 70S SUGGEST 0-1KM ML CAPE POSSIBLY TOPPING 3K J/KG. SO WHILE DEEP LAYER SHEER WILL NOT BE IDEAL...THE DEGREE OF INSTABILITY /STEEP LOW LEVEL LAPSE RATES AND HIGH CAPE DENSITY/ WILL SUPPORT DAMAGING WIND GUSTS WITH ANY THUNDERSTORMS THAT DEVELOP LATE TODAY. THE SPC DAY ONE OUTLOOK CONTINUES TO HAVE LOCATIONS ALONG/SOUTH OF A LINE FROM ROUGHLY NE SANILAC COUNTY TO LANSING IN A SLIGHT RISK. THESE AREAS STAND THE BEST CHANCE TO SIGNIFICANTLY DESTABILIZE. THE POTENTIAL CLOUD COVER AND EARLIER FROPA FARTHER NORTH ADDS A HIGHER DEGREE OF UNCERTAINTY WITH BOTH THE CHANCES FOR CONVECTIVE DEVELOPMENT AND THE POTENTIAL SEVERITY. THE MAIN FORCING MECHANISM FOR CONVECTIVE INITIATION LATER TODAY WILL BE CONVERGENCE ALONG THE COLD FRONT NOW EXTENDING FROM NRN LAKE MI TO NRN MO /AND AS SEVERAL HI RES SOLUTIONS SUGGEST SOME PREFRONTAL TROUGHING/. DAYTIME HEATING AND SUBTLE MID LEVEL HEIGHT FALLS WILL WORK TOWARD OVERCOMING THE CAPPING INVERSION. WHILE ANY STORM WILL PRODUCE HEAVY RAIN TODAY...THE POTENTIAL FOR PROLONGED HEAVY RAIN LOOKS TO BE TONIGHT WHEN THE MID LEVEL MOIST AXIS OVERSPREADS SE MI. THE DEGREE OF UPSCALE GROWTH OF AFTERNOON CONVECTION WILL HOWEVER AFFECT THE RAINFALL CHANCES TONIGHT. IF CONVECTION BECOME WIDESPREAD THIS AFTERNOON...THE INSTABILITY AND MOIST AXIS MY BE SHUNTED SOUTH OF THE STATE MUCH SOONER THAN RECENT MODELS SUGGEST. THUS NO FLOOD WATCH WILL BE ISSUED AT THIS TIME. PREV DISCUSSION...ISSUED 345 AM EDT FRI SEP 5 2014 SHORT TERM...TODAY AND TONIGHT ONE OF THE WARMEST DAYS THIS SUMMER IS EXPECTED TODAY AHEAD OF A COLD FRONT. CONCERNS WILL THEN INCREASE DURING THE AFTERNOON AND EVENING AS A COLD FRONT STARTS TO MOVE ACROSS THE AREA...TRIGGERING STRONG TO POSSIBLY SEVERE THUNDERSTORMS AND THE THREAT FOR VERY HEAVY RAINFALL. UPPER TROUGH TRACKING FROM THE UPPER MISSISSIPPI RIVER VALLEY WILL CONTINUE TO SEND AN AREA OF SURFACE LOW PRESSURE ACROSS ONTARIO AND INTO QUEBEC TODAY...WITH THE SOUTHERN EXTENSION OF SURFACE TROUGHING AND A COLD FRONT DRAGGING ACROSS LOWER MICHIGAN. ACTIVITY ONGOING THIS MORNING OVER NORTHERN AND CENTRAL LOWER MICHIGAN IS TIED TO STRONG THETA-E ADVECTION OCCURRING AHEAD OF THE PASSING LOW...WITH MOISTURE BEING USHERED INTO THE REGION BY A 40-50 KNOT LOW-LEVEL JET. ACTIVITY MAY JUST BRUSH THE SAGINAW VALLEY THIS MORNING BEFORE WE SEE A BREAK IN CONVECTION. ELSEWHERE...A CHANCE OF STORMS IS STILL POSSIBLE AS THE IMPRESSIVE THETA-E RIDGE SETTLES INTO THE AREA BEFORE SUNRISE...AND WE HAVE SEEN A FEW CELLS POP UP OVERNIGHT. QUIETER CONDITIONS ARE EXPECTED FROM SUNRISE THROUGH THE LATE MORNING AS WEAK SHORTWAVE RIDGING ENCOMPASSES THE AREA. MODEL FORECAST SOUNDINGS DURING THIS TIME SHOW QUITE A BIT OF WARM AIR SITUATED BELOW 850MB...PROVIDING A STURDY CAP. AS THE UPPER WAVE TRACKS TO OUR NORTH THIS AFTERNOON...UPPER HEIGHTS WILL START TO FALL AND THE MID-LEVELS WILL START TO COOL. THIS WILL CREATE VERY STEEP LAPSE RATES AS THE SURFACE HEATS...WITH NAM MODEL FORECAST SOUNDINGS SHOWING THE CAP BREAKING BETWEEN 16-19Z (FROM MBS PROGRESSING DOWN TO DTW). THIS WILL SET THE STAGE FOR A GOOD COVERAGE OF SHOWERS AND THUNDERSTORMS TO REDEVELOP THIS AFTERNOON AND CONTINUE INTO THE EVENING AS THE COLD FRONT SLIDES SOUTHEAST ACROSS THE AREA. HEAT AND HUMIDITY WILL ALSO FURTHER INCREASE TODAY AHEAD OF THE FRONT...SENDING TEMPS WELL UP INTO THE 80S AND LOW 90S ACROSS ALL BUT THE NORTHERN PORTIONS OF THE SAGINAW VALLEY. THIS WILL CREATE HEAT INDEX VALUES IN THE LOW TO MID 90S FOR MOST LOCATIONS...AS SURFACE DEWPOINTS NUDGE BACK UP TO AROUND 70 DEGREES. THE POTENTIAL EXISTS FOR STORMS TO BECOME STRONG TO SEVERE THIS AFTERNOON AND EVENING. T/TD VALUES OF 90/70 YIELD 2500-3000 J/KG OF SB/ML CAPE BY THIS AFTERNOON...BUT BULK SHEAR VALUES LOOK TO REMAIN AROUND 20 KNOTS OVER MOST OF THE AREA. SPC HAS PUT US IN A SLIGHT RISK FOR AREAS SOUTH OF A LINE ROUGHLY FROM FLINT TO HARBOR BEACH...WHERE DAYTIME HEATING WILL BE ABLE TO GENERATE MORE INSTABILITY BEFORE THE COLD FRONT APPROACHES. DAMAGING WINDS AND HAIL LOOK LIKE THE GREATEST THREATS WITH FORECAST SOUNDINGS SUPPORTING FAIRLY UNIDIRECTIONAL WIND PROFILES...AND PRETTY GOOD CAPE DENSITIES THROUGH THE 0 TO -20 C LAYER. TORRENTIAL RAINFALL WILL ALSO BE A BIG THREAT WITH PWAT VALUES APPROACHING 2 INCHES...ESPECIALLY WHERE CELLS TRAIN. CHANCES FOR RAINFALL WILL CONTINUE OR BE RENEWED OVERNIGHT...BECOMING LIKELY ALONG AND SOUTH OF THE M-59 CORRIDOR...AS AN UPPER WAVE TRACKING UP FROM THE FOUR CORNERS POTENTIALLY SLOWS THE SOUTHEAST PROGRESS OF THE FRONT OVERNIGHT. MODELS ARE KEYING IN ON THIS WAVE NOW OVER COLORADO AND NEBRASKA (AT 3 AM) TRACKING UP INTO THE AREA OVERNIGHT...ALONG THE FRONT AND UNDER THE RIGHT ENTRANCE REGION OF A JET STREAK. THIS WOULD ACT TO SLOW THE EXIT OF THE FRONT AND INCREASE CONVERGENCE ALONG THIS BOUNDARY TONIGHT...HELPING TO WRING OUT ADDITIONAL MOISTURE. IF WE DO SEE TWO ROUNDS OF HEAVY RAINFALL IT WOULD INCREASE THE POTENTIAL FOR ANY FLOODING OVER THE AREA. CONFIDENCE IN BOTH ROUNDS OF HEAVY RAIN IS JUST NOT HIGH ENOUGH TO JUSTIFY A FLOOD WATCH AT THIS TIME...BUT THIS MAY NEED TO BE RECONSIDERED LATER AS THINGS START TO PLAY OUT. LONG TERM... AFTER LINGERING SHOWERS END SATURDAY MORNING AS MAIN UPPER LEVEL TROUGH AXIS PASSES EAST OF THE AREA...A LARGE SURFACE HIGH PRESSURE SYSTEM WILL BUILD ACROSS A LARGE PORTION OF THE EASTERN CONUS AND BRING DRY WEATHER OVER MUCH OF THE WEEKEND ON INTO EARLY NEXT WEEK. THIS HIGH WILL ALSO BRING COOLER TEMPERATURES ARE HIGHS FALL BACK INTO THE 70S ON AVERAGE AND LOWS RANGE GENERALLY IN THE 50S. THIS QUIET PATTERN BEGINS TO BREAK DOWN BY THE MIDDLE OF NEXT WEEK AS A BROAD UPPER LEVEL TROUGH BEGINS TO DIG DOWN THE HIGH PLAINS OF NOAM AND SHORTWAVE ENERGY RIDES NORTHEAST INTO AREA WITHIN EXPANDING SOUTHWEST UPPER LEVEL FLOW IN ADVANCE OF THIS UPPER TROUGHING. THE CHANCE OF SHOWERS AND THUNDERSTORMS WILL INCREASE IN THE TUESDAY TO WEDNESDAY TIME FRAME WITH LINGERING SHOWERS THROUGH THE REMAINDER OF THE WEEK AS THE AFOREMENTIONED UPPER TROUGH SHIFTS QUICKLY INTO THE NORTHEAST QUADRANT OF THE CONUS. TEMPERATURES WILL REMAIN AVERAGE TO SLIGHTLY BELOW AVERAGE ON INTO THURSDAY BEFORE MUCH COOLER AIR SHIFTS INTO THE AREA WITH THE TROUGH JUST BEYOND THIS FORECAST PERIOD. MARINE... STEADY SOUTH TO SOUTHWEST WINDS WILL PERSIST EARLY THIS MORNING AS WARMER AIR SPREADS NORTH INTO THE REGION. THE STABLE WARM SOUTHERLY FLOW WILL KEEP WIND GUSTS TO A MINIMUM...ALTHOUGH FUNNELING OF THE VEERING SOUTHWEST FLOW IS EXPECTED TO ALLOW FOR GUSTS TO 25 KNOTS OVER SAGINAW BAY THROUGH EARLY THIS MORNING...AND A SMALL CRAFT ADVISORY REMAINS IN EFFECT. THERE REMAINS A CHANCE FOR THUNDERSTORMS FOR ALL WATERS INTO THIS MORNING...BUT ESPECIALLY FOR ROUGHLY THE NORTHERN TWO THIRDS OF LAKE HURON. STORM CHANCES THEN EXPAND LATE FRIDAY INTO FRIDAY NIGHT WITH SEVERE STORMS POSSIBLE...ESPECIALLY FOR THE SOUTHERN LAKE HURON BASIN AND POINTS SOUTH. NORTHWEST WINDS BEHIND THE COLD FRONT FORCING THIS ACTIVITY WILL GUST TO 20 TO 25 KNOTS OVER PARTS OF LAKE HURON FRIDAY NIGHT AND THEN DIMINISH OVER THE WEEKEND AS HIGH PRESSURE SETTLES OVER THE REGION. && .DTX WATCHES/WARNINGS/ADVISORIES...
