Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day
The local office's own words before this tornado warning went out, 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 this tornado warning went out at Jul 18, 7:32 PM EDT, 13 minutes earlier.
Area forecast discussion, Jul 18, 7:32 PM EDT, 13 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 732 PM EDT SUN JUL 18 2010 LATEST UPDATE...AVIATION... .SYNOPSIS...(420 PM EDT SUN JUL 18 2010) THE POTENTIAL FOR SEVERE THUNDERSTORMS WILL CONTINUE INTO THE EVENING WHEN A LOW PRESSURE SYSTEM AND A COLD FRONT WILL MOVE OUT OF THE REGION. THE NEXT CHANCE OF RAIN WILL COMING MONDAY NIGHT AS THE COLD FRONT STALLS TO OUR SOUTH AND A WAVE OF LOW PRESSURE TRACKS ALONG IT. SEVERE POTENTIAL WITH THIS SYSTEM APPEARS TO BE LOW... HOWEVER FAR SOUTHERN LOWER MICHIGAN COULD SEE A SOAKING RAIN THAT COULD LAST INTO TUESDAY. && .SHORT TERM...(420 PM EDT SUN JUL 18 2010) (TONIGHT THROUGH TUESDAY NIGHT) WE ARE MONITORING THE THREAT FOR SEVERE WEATHER FOR THIS EVENING ACROSS THE AREA. ONLY SMALL TWEAKS MADE TO GRIDS. RADAR CURRENTLY INDICATES A LINE OF STRONGER STORMS FROM KENT COUNTY SOUTH TO KALAMAZOO COUNTY. THIS LINE OF STORMS IS LIKELY TO PRODUCE SOME SMALL HAIL AND SOME POSSIBLE WIND GUSTS TO 40-50 MPH. SFC LOW CENTER ACROSS SRN WI AND NRN IL WILL BE MOVING TO THE EAST OUT OF THE AREA THIS EVENING. HAVE KEPT LOW CHANCE POPS GOING FOR THE EARLY EVENING AS A FEW RANDOM SHOWERS OR STORMS WILL BE POSSIBLE AS THE COLD FRONT EXITS. THE FRONT HANGS UP TO OUR SOUTH AND THE MODELS INDICATE A WAVE OF LOW PRESSURE MAY TRACK ALONG IT MONDAY NIGHT INTO TUESDAY. SEVERE POTENTIAL SHOULD BE MINIMAL IN THIS TIME FRAME...HOWEVER THERE WILL BE THE POTENTIAL FOR HEAVY RAIN ACROSS THE SOUTHERN CWA. THERE STILL IS A FAIR AMOUNT OF DIFFERENCES IN THE MODELS ON HOW THIS UNFOLDS. SO HAVE MAINTAINED CHANCE POPS...HIGHEST IN THE SOUTH. && .LONG TERM...(1007 AM EDT SUN JUL 18 2010) (WEDNESDAY THROUGH SUNDAY) LATEST MODEL RUNS FOR THE LONG TERM INDICATE LITTLE TO NO CHANGE IS NEEDED FOR THE FCST. ZONAL FLOW IS EXPECTED TO HOLD IN ACROSS THE NRN HALF OF THE COUNTRY. THIS ZONAL FLOW WILL CONTINUE TO INTERACT WITH THE VERY WARM AND VERY MOIST CONDITIONS JUST SOUTH OF THE JET. IT STILL APPEARS THAT THERE WILL BE NUMEROUS CHCS OF CONVECTION THIS WEEK WITH THE NEARLY STATIONARY FRONTAL BOUNDARY EXPECTED TO SET UP SHOP JUST SOUTH OF THE AREA. AS WAVES OF LOW PRESSURE MOVE ALONG IT...THIS FRONT WILL TRY TO BULGE TO THE NORTH AND WILL SUPPORT THE THREAT FOR CONVECTION. WE DID TRY TO PIN DOWN A COUPLE OF OPPORTUNITIES WHERE THE THREAT MAY BE A LITTLE LESS BEHIND A COUPLE OF STRONGER WAVES INDICATED BY MULTIPLE MODELS. IT APPEARS THAT WED MAY HAVE A BETTER CHC OF BEING A LITTLE DRIER THAN THE REST OF THE WORK WEEK AS A STRONGER WAVE PUSHES THE FRONT A LITTLE FARTHER SOUTH. NEXT SUNDAY ALSO HAS THE POTENTIAL OF BEING DRY AS ANOTHER STRONGER WAVE MOVES THROUGH ON SAT AND PUSHES THE FRONT SOUTH IN ITS WAKE. && .AVIATION...(732 PM EDT SUN JUL 18 2010) ISOLATED THUNDERSTORMS WILL DIMINISH TO SHOWERS AND END TONIGHT AS A COLD FRONT MOVES AWAY FROM THE AREA. WINDS WILL DECREASE TO BELOW 10 KNOTS AND SWING TO THE NORTHWEST. LIGHT FOG... HAZE AND IFR CEILINGS WILL BECOME POSSIBLE TONIGHT AS LOW LEVEL MOISTURE REMAINS BEHIND THE FRONT. LOCALLY DENSE FOG IS ALSO POSSIBLE... THOUGH MOST LOCATIONS SHOULD HAVE VISIBILITIES OF 3 MILES OR GREATER. VFR CONDITIONS WILL PREVAIL MONDAY AFTERNOON AND EVENING AFTER THE CLOUDS AND FOG DISSIPATE. && .MARINE...(420 PM EDT SUN JUL 18 2010) CONDITIONS ARE EXPECTED TO IMPROVE AFTER SUNSET THIS EVENING AS THE STORM SYSTEM EXITS AND WINDS DIMINISH. RATHER LIGHT WINDS AND LOW WAVES ARE EXPECTED AFTER MIDNIGHT AND THIS WILL CONTINUE THROUGH MONDAY NIGHT. && .HYDROLOGY...(420 PM EDT SUN JUL 18 2010) TODAY/S ROUND OF STORMS SHOULD BE FAIRLY FAST MOVERS OF AROUND 40 MPH WHICH SHOULD LIMIT ANY ONE AREA FROM RECEIVING HIGH RAINFALL TOTALS. MOST AREAS SHOULD SEE AROUND A HALF INCH OF RAIN...WITH LOCALIZED AREAS PERHAPS SEEING A LITTLE OVER AN INCH OF RAIN. OVERALL THE HYDRO THREAT APPEARS LOW. ITS UNCLEAR HOW THE MONDAY NIGHT AND TUESDAY EVENT WILL UNFOLD. BUT THERE IS POTENTIAL FOR HEAVY RAINS ACROSS FAR SOUTHERN LOWER MI. A STATIONARY FRONT WILL LIE NEAR THE MI/IN BORDER AND WAVES OF HEAVY RAIN WILL TRACK ALONG IT. WHERE EXACTLY THIS SETS UP THOUGH IS THE QUESTION. PWAT VALUES CLIMB TO NEAR TWO INCHES LEADING TO THE CONCERN. && .GRR WATCHES/WARNINGS/ADVISORIES... MI....NONE. LM....NONE. && SYNOPSIS: JK/53 SHORT TERM: JK/NJJ/63 LONG TERM: NJJ AVIATION: OSTUNO/63 MARINE: 63 HYDROLOGY: JK/63
