The episode as NWS GRR wrote it up.
Severe thunderstorms moved quickly across southern lower Michigan during the late afternoon and evening hours of September 5th, causing significant tree damage and power outages. The cities of Kalamazoo and Eaton Rapids, in particular, were hit hard by severe straight line winds where numerous large trees and power lines were blown down. There were many reports of tree damage and thousands of people without power from Van Buren and Allegan counties eastward through Barry, Kalamazoo, Calhoun, Eaton, Ingham, and Jackson counties.
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 Grand Rapids, MI wrote its last area forecast discussion before the first event at Sep 5, 2:26 PM EST, 1 hour 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 326 PM EDT FRI SEP 5 2014 LATEST UPDATE... MESOSCALE DISCUSSION/SYNOPSIS/SHORT TERM/LONG TERM/HYDRO/MARINE .MESOSCALE DISCUSSION... ISSUED AT 326 PM EDT FRI SEP 5 2014 EXTREME INSTABILITY HAS BUILT ACROSS THE SE THIRD OF THE CWFA WITH ML CAPES OVER 3500 J/KG AHEAD OF THE COLD FRONT. THE COLD FRONT AS OF 19Z IS ROUGHLY FROM SAGINAW BAY...TO JUST SE OF GRAND RAPIDS...TO JUST NORTH OF SOUTH HAVEN. BEST EFFECTIVE SHEAR IS INCREASING IMMEDIATELY BEHIND THE FRONT. WE EXPECT THAT THE FRONT WILL LIGHT UP VERY SOON WITH GOOD ASSOCIATED SFC MOIST CONVERGENCE...AND BECOME A SOLID LINE AS THE FRONT PUSHES SOUTHEAST. BIGGEST THREATS WITH THE STORMS ARE EXPECTED TO BE DAMAGING WINDS WITH A UNIDIRECTIONAL PROFILE AND FORMIDABLE WINDS ALOFT ALONG WITH DRY MID AND UPPER LEVELS...LARGE HAIL WITH THICK CAPE IN THE -10C TO -30C LAYER...AND HEAVY RAINFALL WITH PRECIPITABLE WATERS APPROACHING 2 INCHES. && .SYNOPSIS... ISSUED AT 326 PM EDT FRI SEP 5 2014 A STRONG COLD FRONT WILL CONTINUE TO MOVE THROUGH SOUTHERN LOWER MICHIGAN THIS EVENING. STRONG TO SEVERE THUNDERSTORMS ARE LIKELY TO ACCOMPANY THIS FRONT INTO THE EARLY EVENING HOURS BEFORE SHIFTING SOUTH OF THE STATE. A WAVE WILL THEN MOVE ACROSS THE AREA OVERNIGHT BRINGING MORE RAIN TO SOUTHERN LOWER MICHIGAN. MUCH COOLER AND DRIER AIR WILL MOVE INTO THE AREA ON SATURDAY. HIGH PRESSURE WILL TAKE CONTROL OF THE WEATHER FOR THE AREA THROUGH AT LEAST MONDAY. PLENTY OF SUNSHINE CAN BE EXPECTED DURING THE DAYLIGHT HOURS. THE NEXT CHANCE OF RAIN WILL COME DURING THE DAY ON TUESDAY WITH THE NEXT FRONTAL SYSTEM. && .SHORT TERM...(THIS EVENING THROUGH SUNDAY NIGHT) ISSUED AT 326 PM EDT FRI SEP 5 2014 THE MAIN FOCUS OF THE SHORT TERM PORTION OF THE FCST WILL BE ON THE CONVECTIVE TRENDS AND SEVERE WEATHER POTENTIAL THROUGH TONIGHT. WE EXPECT THAT THE SEVERE WEATHER POTENTIAL WILL BE PRESENT THROUGH EARLY THIS EVENING ACROSS THE SOUTHERN PORTION OF THE AREA BEFORE THE THREAT DIMINISHES GREATLY BY 00Z THIS EVENING. INSTABILITY CONTINUES TO BUILD ACROSS THE SRN PORTION OF THE CWFA WHERE PLENTY OF SUNSHINE HAS BEEN PRESENT ALL DAY TODAY. COLD FRONT LOOKS TO EXTEND FROM NEAR SAGINAW BAY TO JUST SE OF GRAND RAPIDS TO JUST NORTH OF SOUTH HAVEN AS OF 19Z THIS AFTERNOON. IT IS SOUTH OF THIS FRONT WHERE THE BEST SEVERE WX POTENTIAL WILL BE FOUND. THE FRONT IS EXPECTED TO PUSH SOUTH OF THE CWFA BY 00Z THIS EVENING...ESSENTIALLY ENDING THE SEVERE THREAT. PLEASE SEE THE MESOSCALE DISCUSSION ABOVE FOR MORE DETAILS. WE ARE LOOKING AT A SECONDARY BAND OF SHOWERS AND AN EMBEDDED STORM THEN MOVING IN LATER THIS EVENING AND CONTINUING OVERNIGHT TONIGHT. THE FRONT SLOWS DOWN FOR A BIT JUST SOUTH OF THE CWFA AS WE HAVE UPPER ENERGY THAT IS GOING TO INDUCE MORE PCPN OVERNIGHT. THERE IS A NICE SHORT WAVE THAT IS CROSSING THE MO RIVER THIS AFTERNOON THAT IS MOVING ENE AS THE UPPER TROUGH COMING DOWN FROM CANADA PICKS IT UP. MODELS INDICATE A GOOD DEAL OF MID LEVEL FGEN MOVING IN/DEVELOPING OVER THE AREA BY 06Z TONIGHT AS THIS WAVE INTERACTS WITH THE FRONTAL ZONE. THE BEST CHC OF PCPN WILL ONCE AGAIN BE FURTHER SE...CLOSER TO THE SFC FRONT AND BEST MOISTURE. THIS PCPN COULD EXTEND TO THE NW OVER A GOOD PORTION OF THE CWFA. THUNDER CHANCES WITH THE OVERNIGHT PCPN LOOK RATHER SMALL. INSTABILITY OVERNIGHT DROPS TO ABOUT NOTHING AS THE FRONTAL ZONE AT THE SFC AND ALOFT SHIFTS SE WITH TIME. WITH THE INSTABILITY WANING...SEVERE THREAT IS QUITE LOW...IF THERE IS ANY AT ALL. THE RAINFALL COULD BE AN ISSUE AS IT WILL AFFECT LOCATIONS THAT COULD SEE HEAVY RAIN WITH THE FIRST BATCH THIS AFTERNOON. THIS SHOULD ALL MOVE OUT PRETTY MUCH BY 12Z SAT AS THE SHORT WAVE MOVES EAST OF THE AREA. THE REST OF THE PERIOD WILL FEATURE QUIET WEATHER WITH COOL AND MUCH LESS HUMID CONDITIONS THEN AS HIGH PRESSURE BUILDS IN OVER THE AREA. WE COULD SEE SOME BREEZY CONDITIONS FOR A GOOD PART OF THE DAY ON SAT AS THE GRADIENT AHEAD OF THE RIDGE MOVES OVER AND IS ENHANCED BY THE LAKE. THIS WILL WEAKEN LATER SAT. .LONG TERM...(MONDAY THROUGH FRIDAY) ISSUED AT 326 PM EDT FRI SEP 5 2014 LITTLE QUESTION OUR WEATHER IS BECOMING MORE FALL LIKE. THE MOST SIGNIFICANT ISSUE WITH THE LONG RANGE FORECAST IS THE SYSTEM IN THE THURSDAY TIME FRAME. THIS COULD BRING THUNDERSTORMS AND LOCALLY HEAVY RAINFALL. BEHIND IT THE AIR BECOMES COLD ENOUGH FOR LAKE EFFECT RAIN SHOWERS. THE MODELS ARE IS REASONABLE AGREEMENT TILL WEDNESDAY. IT IS AT THAT POINT THE ECMWF IS MUCH DEEPER AND SLOWER WITH A CLOSED UPPER LOW COMING INTO THE GREAT LAKES THAN IS THE GFS. ACTUALLY THE GFS NEVER ACTUALLY CLOSES OFF THE UPPER LOW LIKE THE ECMWF DOES. SINCE THE ECMWF HAS BEEN MORE CONSISTENT WITH THE SYSTEM THAN THE GFS I AM LEANING IN THE DIRECTION OF THE ECMWF. THAT WOULD BRING WARMER AND MORE UNSTABLE AIR FATHER NORTH AND RESULT IN THUNDERSTORMS WEDNESDAY NIGHT INTO THURSDAY. EITHER WAY THROUGH WE WOULD HAVE WILL SEE SHOWERS WEDNESDAY INTO THURSDAY. PRIOR TO THAT EXPECT HIGH PRESSURE TO RESULT IN SLIGHTLY BELOW NORMAL TEMPERATURES...MOSTLY CLEAR SKIES AND LIGHT WINDS. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON) ISSUED AT 125 PM EDT FRI SEP 5 2014 A COMPLEX FORECAST FOR SURE. THERE IS CURRENTLY A BAND OF MVFR CIGS JUST AHEAD OF THE COLD FRONT BUT VERY LITTLE IN THE WAY OF CONVECTION. I TIMED THE MVFR CIGS THROUGH THE TAF SITES AHEAD OF THE COLD FRONT. I ALSO PUT VCTS AT MOST OF THE TAF SITES BUT REALISTICALLY IT WOULD SEEM (BASED ON WHERE IT IS CURRENTLY SUNNY) JXN AND LAN HAVE THE BEST CHANCE OF GETTING ONE OF THOSE THUNDERSTORMS. TONIGHT A STRONG SHORTWAVE IN COMBINATION WITH THE JET ENTRANCE REGION LIFT WILL BRING AND AREA OF SHOWERS ACROSS THE TAF SITES BETWEEN 06Z AND 12Z. THAT MAY RESULT IN MVFR/IFR CIGS/VSBY FOR SEVERAL HOURS OVERNIGHT. ONCE THAT IS THROUGH...AROUND 12Z SKIES SHOULD CLEAR FOR THE DAY TIME HOURS OF SATURDAY. && .MARINE... ISSUED AT 326 PM EDT FRI SEP 5 2014 WE WILL BE KEEPING THE NEARSHORE WATERS HEADLINE FREE FOR THIS COMING WEEKEND. WINDS AND WAVES WILL REMAIN UP SOME ON SATURDAY AS THE COOLER AIR ADVECTS IN AND HIGH PRESSURE BUILDS INTO THE AREA. WE EXPECT THESE TO STAY JUST BELOW SMALL CRAFT ADVISORY CRITERIA. THE AREA OF HIGH PRESSURE SHOULD BE ALMOST OVERHEAD ON SUNDAY BRINGING WINDS UNDER 15 KNOTS AND LITTLE IF ANY WAVES FOR THE SECOND HALF OF THE WEEKEND. && .HYDROLOGY... ISSUED AT 326 PM EDT FRI SEP 5 2014 HEAVY RAINFALL WILL BE A CONCERN THROUGH TONIGHT...ESPECIALLY FOR SOUTHERN AREAS. PRECIPITABLE WATERS ARE RUNNING AROUND JUST BELOW 2 INCHES AHEAD OF THE FRONT. ONE LINE OF STORMS WITH HEAVY RAIN IS EXPECTED THE FURTHER SOUTH AND EAST YOU GO. THE STORMS WILL MOVE STEADILY TO THE SOUTHEAST...HOWEVER SOME SHORT TERM TRAINING WITH HEAVY RAINFALL RATES COULD PRODUCE SOME LOCAL URBAN FLOODING. ANOTHER BAND OF RAIN IS EXPECTED TO FORM THIS EVENING AND WILL AFFECT THE SRN PORTION OF THE AREA ALSO OVERNIGHT. THIS SECOND BATCH OF RAIN WILL NOT BE AS HEAVY AS DRIER AIR STARTS TO WORK INTO THE AREA. HOWEVER IT COULD EXACERBATE ANY ISSUES THAT OCCUR WITH THE FIRST LINE. DRY WEATHER THIS WEEKEND AND EARLY NEXT WEEK WILL ALLOW THE RIVERS AND STREAMS TO START TO RECOVER FROM HEAVY RAINFALL TODAY. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...NONE.
