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 Jul 25, 2:08 PM EST, 2 hours 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 308 PM EDT SAT JUL 25 2015 .SHORT TERM...TONIGHT DIFFUSE COLD FRONT WILL CONTINUE TO MOVE THROUGH SOUTHEAST MICHIGAN DURING THE EVENING HOURS. DURING THE MID AFTERNOON THE FIRST FRONT LIED FROM THE NW SIDE OF SAGINAW BAY TO MKG. SHOWERS AND STORMS WERE DEVELOPING ALONG THIS FEATURE. THE MAIN PRESSURE TROF IS ASSOCIATED WITH THIS SLIGHT WIND SHIFT TO THE WNW AND SLIGHTLY LOWER DEW POINTS. THE DRIER AIR IS ASSOCIATED WITH SECOND FRONT AS WINDS TURN TO THE NORTH FROM HARRISVILLE TO PENTWATER. ANALYSIS SUGGESTS THERE IS SOME MOISTURE BEING ADVECTED AHEAD OF THESE FRONTAL SYSTEMS WITH ML CAPES EXCEEDING 1000 J/KG. 0-6KM BULK SHEAR IS STILL ABOVE AROUND 35 KTS. THIS ALL SUGGESTS THAT THE CURRENT FORECAST THINKING OF SCATTERED SHOWERS AND STORMS WITH AN ISOLATED THREAT OF A SEVERE STORM IS STILL ON TARGET. HI RES RUNS ALSO STILL SUGGEST THAT BULK OF THE ACTIVITY COULD BE DONE BY 22Z-00Z. THAT SECOND COLD FRONT MAY BE ENOUGH TO TRIGGER A SHOWER OR STORM AND WILL ADD A SMALL CHANCE POP FROM 00Z TO 03Z FOR AREAS SOUTH OF A PHN TO OZW LINE. CLEARING TAKES PLACE FROM 00Z TO 06Z ACROSS THE FORECAST AREA AS THE WINDS BECOMES LIGHT FROM THE NORTH. GIVEN THE CLEAR SKIES AFTER MIDNIGHT AND DEW POINTS BEHIND THE FRONT AROUND 60...WILL LOWER LOW TEMPS A FEW DEGREES WHICH IS IN LINE WITH GUIDANCE NUMBERS TONIGHT. && .LONG TERM... SUNDAY THROUGH MONDAY PRETTY QUIET PERIOD AFTER FRONT PASSES THROUGH OVERNIGHT... WEAK HIGH PRESSURE WILL CENTER ITSELF OVER THE GREAT LAKES WITH NEXT PRECIP CHANCES HOLDING OFF UNTIL THE NEXT APPROACHING FRONT MID WEEK. NOT MUCH IN THE WAY OF COLD ADVECTION BEHIND THE FRONT AND WITH A LITTLE DRIER AIR MASS AND PLENTY OF SUN... EXPECTING GFS MAX TEMPS NEAR 90 ARE LIKELY WITHIN REACH SUNDAY AND MONDAY. FAIRLY LIGHT WINDS CONTINUING .. SFC DEW POINTS SHOULD NOT LOWER A HUGE AMOUNT GIVEN THE HEALTHY STATE OF VEGETATION IN THE AREA. UPPER RIDGE EXTENDING INTO THE WESTERN GREAT LAKES TUESDAY WILL GIVE WAY TO LOWERING HEIGHTS WEDNESDAY AS AN UPPER LOW TRACKS ACROSS SOUTHERN CANADA. THIS PROCESS WILL DRAG A COLD FRONT THROUGH SOUTHEAST MICHIGAN IN THE WEDNESDAY/WED NIGHT TIME FRAME WHICH RESULTS IN OUR NEXT CHANCE OF THUNDERSTORMS. VERY WARM AND HUMID CONDITIONS WILL CONTINUE TUE/WED...WITH A COOLER/DRIER AIRMASS IN THE OFFING FOR THE END OF THE WEEK IN THE WAKE OF THE COLD FRONT. && .MARINE... A FEW THUNDERSTORMS EARLY THIS EVENING ALONG THE COLD FRONT FROM FAR SOUTHERN LAKE HURON AND POINTS SOUTHWARD. THIRTY KNOT WINDS NOT TOO FAR OFF THE SURFACE ON THIS MORNINGS SOUNDING SO IT COULD GET A LITTLE GUSTY ON THE LEAD EDGE OF THESE STORMS. AFTER THAT... LIGHT WINDS AND NO PRECIP FOR THE NEXT 2-3 DAYS. NEXT FRONT SHOULD APPROACH THE AREA TUESDAY NIGHT BRINGING ANOTHER CHANCE OF THUNDERSTORMS TO ALL OF THE LAKES. && .AVIATION...ISSUED 1255 PM EDT SAT JUL 25 2015 A COLD FRONT WAS LOCATED FROM OSC TO MKG AND WILL MOVE THROUGH SOUTHEAST MICHIGAN THIS AFTERNOON AND EVENING. SHOULD GET THROUGH MBS BY 20Z...FNT BY 21-22Z AND DTW BY 00Z THIS FRONT WILL BRING A WINDOW OF LOWER CIGS AND POSSIBLE TSTORMS. VFR CONDITIONS WILL PREVAIL BOTH BEFORE AND AFTER THIS NARROW WINDOW OF THE FRONTAL PASSAGE IN WHICH MVFR CIGS/VSBYS MAY OCCUR. CONFIDENCE IS LOW WITH COVERAGE OF POTENTIAL TSTORMS AS SIGNALS ARE POINTING TO ISOLATED/SCATTERED COVERAGE. WILL INCLUDE A BRIEF 2 HOUR TEMPO TO ACCOUNT FOR THIS NARROW WINDOW OF POTENTIAL FOR PTK SOUTHWARD WITH JUST SHOWERS FOR FNT/MBS DUE TO EARLIER TIMING AND LESS INSTABILITY. NORTHERLY WINDS BEHIND THE FRONT WILL BRING DRIER AIR BACK TO THE AREA ERODING THE CLOUDS THIS EVENING INTO THE OVERNIGHT FROM NORTH TO SOUTH. WINDS HAVE BRIEFLY INCREASED FROM THE SW AHEAD OF THE FRONT BUT WILL RELAX SOME OVERNIGHT AS WIND SWITCH TO NORTHERLY WITH THE NEXT HIGH SETTLING IN. FOR DTW...COLD FRONT LOOKS TO BE MOVING THROUGH DURING PEAK HEATING...WARRANTING THE TEMPO FOR TSTORMS FROM 21-23Z. UPSTREAM OBS AND FORECAST SOUNDINGS SUGGEST CIGS WILL HOVER NEAR THE VFR/MVFR THRESHOLD BUT THINKING IS VFR WILL DOMINATE WITH MVFR BEING MORE SCATTERED SO WILL FAVOR VFR WITH THE TAFS. //DTW THRESHOLD PROBABILITIES... * MEDIUM FOR CIGS AOB 5KFT THIS AFTERNOON AND EVENING. * LOW FOR THUNDERSTORMS THIS AFTERNOON. && .DTX WATCHES/WARNINGS/ADVISORIES...
