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 Jun 16, 2:57 PM EST, 1 hour 58 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 357 PM EDT THU JUN 16 2011 .SHORT TERM...THIS EVENING AND TONIGHT WATER VAPOR IMAGERY NOW SHOWS CENTER OF UPPER LEVEL CIRCULATION IN THE EXTREME SE CORNER OF THE STATE. SFC LOW APPEARS TO STILL BE UP NEAR TVC WITH THE TROUGH EXTENDING SE TOWARD LAKE ERIE. STRONGEST FORCING REMAINS IN SOUTHERN 4 COUNTIES THIS AFTERNOON AS A VORT MAX SWINGS THROUGH FWA/TOL COLLOCATED WITH THE SOUTHERN FLANK OF THE H5 CLOSED LOW. INSTABILITY AVAILABLE FOR NEAR STORM ENVIRONMENT IN THE SE MI AREA IS 800 TO 1600 J/KG AND LI VALUES NEAR -2. MOISTURE WITH THIS SETUP IS MARGINAL WITH SFC TD NEAR 55-60F AND 1000-500MB LAYER RH RANGING FROM 70-90 PERCENT. A FEW MORE STRONG CELLS MAY DEVELOP THROUGH ABOUT 00Z...THEN THE LOSS OF DAYTIME HEATING AND EXIT OF SFC/UPPER LOWS WILL DIMINISH PRECIP CHANCES. TRENDED CLOSER TO GUIDANCE FOR MINS TOMORROW (DOWN 1 MOST SPOTS)...BUT STILL ABOUT 1-2 HIGHER THAN MOS. STILL THINKING PATCHY FOG WILL DEVELOP OVERNIGHT GIVEN LIGHT WINDS AND RESIDUAL MOISTURE IN THE BOUNDARY LAYER. && .LONG TERM...FRIDAY THROUGH WEDNESDAY A FLATTENED 500-300MB RIDGE WILL RELEASE/BUILD NORTHWARD EARLY DURING THE FORECAST PERIOD AS A WEAK SHORTWAVE TRAVELS EASTWARD THROUGH PORTIONS OF PA/NJ AND INTO THE ATLANTIC OCEAN. AN ONSLAUGHT OF WARM AIR AND MOISTURE ADVECTION IS EXPECTED INTO THE RIDGE AXIS OVER THE FAR WESTERN GREAT LAKES WHICH WILL SHARPEN A BAROCLINIC ZONE IMMEDIATELY UPSTREAM OF THE CWA. THUS...MODEL GUIDANCE IS NOISY IN TERMS OF PRECIPITATION POTENTIAL ALONG THE QUASI STATIONARY FRONT...WITH CHANCES ULTIMATELY DEPENDENT UPON REMNANT/DECAYING MESOSCALE CONVECTIVE SYSTEMS (FRIDAY NIGHT THROUGH SATURDAY NIGHT). FRIDAY...MODELS DEPICT THAT A WEAK BUT WELL ORGANIZED PV ANOMALY WILL BE WORKING THROUGH PA DURING THE FRIDAY PERIOD. THIS WILL PLACE SOUTHEASTERN MICHIGAN IN THE SUBSIDENCE AND GEOPOTENTIAL HEIGHT BUILDING WAKE OF THE FEATURE. SOME DISAGREEMENT EXISTS BETWEEN NAM/GFS SOUNDINGS...BUT BOTH ARE SUPPORTIVE OF A SUBSIDENCE INVERSION BETWEEN 850-600MB. THE DATA SUPPORTS DEWPOINTS IN THE UPPER 50S TO NEAR 60 WHICH WILL MAKE CONVECTIVE INITIATION A NON ISSUE. HOWEVER...A DECENT CU FIELD IS EXPECTED. HIGHS FRIDAY WILL RANGE IN THE UPPER 70S TO NEAR 80 DEGREES. NWP GUIDANCE IS PEGGING CONVECTIVE DEVELOPMENT OVER PORTIONS OF E IA/N IL/S WI LATE FRIDAY AND FRIDAY NIGHT. PRIMARY DRIVER FOR THIS CONVECTION WILL BE A FAVORABLE WARM AIR ADVECTION REGIME ON THE NOSE OF A LOW LEVEL JET. THE BAROCLINIC ZONE WILL BE IN A NORTHWEST TO SOUTHEAST ORIENTATED LINE FROM NORTHERN ILLINOIS DOWN THROUGH PORTIONS OF SOUTHWESTERN OHIO. A REMNANT STABLE AIRMASS WILL BE IN PLACE SHELTERING THE FORECAST AREA...WHICH LEADS BELIEF THAT THE UPSTREAM CONVECTION WILL LARGELY BE GUIDED TO THE SOUTH. A COMPLICATING FACTOR IS THAT ENHANCED MID TO UPPER LEVEL DEFORMATION WITH THIS LARGER WAVE IS ADVERTISED TO SWEEP ACROSS THE FAR SOUTHERN COUNTIES PRIMARILY VERY LATE FRIDAY NIGHT AND SATURDAY MORNING. NEVER FEEL COMFORTABLE GOING ABOVE CHANCE POP IN THESE SETUPS...BUT BETTER CHANCE SHOULD TIME BETWEEN 12-18Z ON SATURDAY (SOUTH OF THE M59 CORRIDOR). CHARACTER OF THE PRECIPITATION AT THIS TIME...WILL LIKELY BE STRATIFORM. THE TEMPERATURE FORECAST IS TOUGH FOR SATURDAY...BUT GIVEN THE TIME OF YEAR AND STRENGTH OF INSOLATION ALWAYS FAVOR A WARMER FORECAST TO ACCOUNT FOR ANY BREAKS IN THE OVERCAST. HIGHS SATURDAY IN THE UPPER 70S TO AROUND 80 DEGREES. AN OLD AND DEAMPLIFYING UPPER LEVEL RIDGE AXIS WILL SWEEP ACROSS LOWER MICHIGAN ON SUNDAY. THIS WILL BRING A DRY AIRMASS TO THE STATE AND DRY WEATHER. THE TRUE HOT WEATHER WILL REMAIN WELL WEST OF THE CWA...BUT ENOUGH INSOLATION WILL ALLOW TEMPERATURES TO CLIMB ABOVE 80 FOR MANY AREAS. A MORE AMPLIFIED RIDGE AXIS WILL BUILD INTO THE STATE EARLY NEXT WEEK. THE ISENTROPIC LIFT AND WARM AIR ADVECTION ARM WILL LIFT THROUGH THE STATE BEGINNING SUNDAY NIGHT. THE FORECAST WILL READ A LOW CHANCE FOR SHOWERS AND THUNDERSTORMS EARLY NEXT WEEK...BUT THERE ARE NO EXPECTATIONS FOR AN OVERLY WET PERIOD. TEMPERATURES WILL SURGE ON TUESDAY AS THE SURFACE WARM FRONT WILL BE NORTH OF THE AREA...HIGHS WILL MAKE A RUN AT 90 DEGREES. RAISED TEMPERATURES A FAIR AMOUNT FOR WEDNESDAY...AS TREND IN THE MODELS HAS BEEN FOR A SLOWER PASSAGE OF A COLD FRONT (ATTM...WEDNESDAY EVENING). && .MARINE... UPPER LEVEL CIRCULATION CONTINUES TO PROGRESS TOWARDS WESTERN LAKE ERIE THIS AFTERNOON. INFLUX OF MOISTURE ON THE NE FLANK OF THE LOW CONTINUES TO STREAM SHOWERS AND STORMS INTO SOUTHERN LAKE HURON THROUGH EARLY EVENING. NOT MUCH COLD AIR INTRUSION OR OTHER FUEL FOR STRONG WIND GUSTS WITH THE PASSING OF THIS FRONTAL SYSTEM...SO NO STRONG WIND THREATS FOR SEVERAL DAYS. ADDITIONAL RAIN CHANCES AFTER THIS WEEKEND...PRETTY MINIMAL THREAT IN THE MEANTIME. && .AVIATION...ISSUED 151 PM EDT THU JUN 16 2011 //DISCUSSION... OCCLUDED FRONT/TROUGH OF LOW PRESSURE CONTINUES TO LIFT NORTHEAST THROUGH SE MICHIGAN. CLEARING SKIES BEHIND THE FRONT HAS ALLOWED SOME CU TO POP UP AND INSTABILITY HAS INCREASED FROM PTK SOUTHWARD. EXPECT SOME SHOWERS AND ISO TSTORMS THROUGH 00Z...THEN THE LOSS OF DAYTIME HEATING AND EXIT OF LOW PRESSURE WILL CLEAR PRECIP CHANCES. SOME SFC MOISTURE TRAPPED UNDER A MODERATE INVERSION WILL LEAD TO GROUND FOG THROUGH ABOUT 13Z. SOME MOISTURE WILL REMAIN PRESENT FRIDAY BUT ONLY ENOUGH FOR VFR CLOUD DECKS. DIURNAL EFFECTS MAY ALLOW VERY ISOLATED SHOWERS...BUT TOO LOW CONFIDENCE TO MENTION IN TAFS. FOR DTW... CLUSTER OF TSTORMS APPROACHING FROM THE WEST WORTHY OF A TEMPO MENTION...THOUGH BACK EDGE OF SHOWER ACTIVITY MAY LAST SLIGHTLY LONGER. STILL EXPECTING LOW STRATUS TONIGHT UNDER A MODERATE INVERSION...BUT SHOULD ONLY DROP TO MVFR CONDITIONS. //DTW THRESHOLD THREATS... * MEDIUM CONFIDENCE IN THUNDERSTORMS OCCURRING 18-20Z. * LOW CONFIDENCE CEILINGS WILL REMAIN BELOW 5000 FEET THIS AFTERNOON AND DAYTIME FRIDAY. && .DTX WATCHES/WARNINGS/ADVISORIES...
