An isolated severe thunderstorm produced wind damage in the Lake Leelanau area.
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 Gaylord, MI wrote its last area forecast discussion before the first event at Jun 3, 8:32 PM EST, 1 hour 7 minutes earlier.
Area Forecast Discussion National Weather Service Gaylord MI 932 PM EDT Sat Jun 3 2017 .UPDATE... Issued at 923 PM EDT Sat Jun 3 2017 Earlier scattered convection across western upper Michigan has congealed nicely, now a well organized linear complex extending from eastern upper Michigan southwest through central Wisconsin. Northern extent of this activity has displayed a definite weakening trend, with deeper more organized updrafts building more south with time across eastern Wisconsin into Lake Michigan (following instability gradient). Simply see no reason for this not to continue, with latest SPC analysis and simple observational trends showing greatest instability gradient remaining mostly to our west, providing a path for more vigorous and sustained updrafts. Latest SPC day one outlook displaying this trend nicely, removing all of the slight risk and confining marginal severe threat area to our southwest continues. Still think most areas will receive some rain (with perhaps some embedded thunderstorms) but the overall severe threat, limited as it was, is diminishing quickly across much of the region. Still cannot completely rule out an isolated severe wind gust, particularly in our far southwest counties. Best rain threat will end quickly from west to east during the early morning. && .NEAR TERM...(Tonight through Sunday) Issued at 401 PM EDT Sat Jun 3 2017 ...Showers and Storms Tonight... High Impact Weather Potential...Isolated severe storms possible tonight. Height falls from an incoming trough dropping down from the northwest in conjunction with increasing moisture (precipitable waters top out around 1.5 inches late tonight) is expected to lead to the development of a cluster of showers and embedded thunderstorms later tonight into early Sunday. This activity is expected to sweep across the region late tonight into early Sunday. Modest shear (0-6 km bulk shear 30 to 40 kts) could lead to isolated severe storms with damaging wind gusts the primary threat; heavy downpours are also possible. After a likely break Sunday morning, instability driven showers and possible non-severe thunderstorms are then possible Sunday afternoon. Lows tonight in the muggy 50s to lower 60s. Highs Sunday ranging from the middle 60s across eastern upper to near 80 across southern zones. && .SHORT TERM...(Sunday night through Tuesday) Issued at 401 PM EDT Sat Jun 3 2017 High Impact Weather Potential: Minimal. Pattern Forecast: Pair of short wave troughs across central/eastern Canada will be the focus heading into the early part of next week. One short wave trough was moving through Manitoba this afternoon and will dig southeast across the upper Lakes Sunday...while a smaller piece of energy along the eastern shore of Hudson Bay will drop due south and merge with the Manitoba wave to create a new trough with a mid level closed circulation...effectively replacing an upper low currently moving out into Atlantic Canada in a discontinuous retrogression sort of fashion. This feature will spin into the lower Lakes Tuesday keeping broad cyclonic flow in place across the forecast area into midweek. North/northeast winds associated with a surface cyclone will wrap cooler air back into Michigan Monday... which will persist into Tuesday though high pressure will be building in from the northwest later in the day. Primary Forecast Concerns: Precipitation chances with expected impact of upper level energy on the region into at least Monday evening (looking dry beyond). Sharp Manitoba short wave trough will swing across MI/WI Sunday night...and is expected to be accompanied by showers and may some thunderstorms across northern Lower where there will be some lingering instability especially during the evening. Small sliver of northeast Lower in the marginal severe risk for Sunday...actually looks more like that if any thunderstorms can get going across northern Lower there could be a severe risk given vertical shear profiles. Consensus forecast PoPs thin out a bit too quick early Monday morning for my liking at least across northern Lower where mass fields suggest some showers may linger. Somewhat deep layer cyclonic flow on Monday with the tail end of a PV anomaly rotating west/southwest out of Ontario and into Michigan...along with associated mid level cooling (500mb temperatures falling below -20C). Could just be enough to squeeze out a few showers across the eastern half of the forecast area Monday afternoon...and perhaps into Monday night/early Tuesday if deeper layer moisture can scrape northeast Lower. Some developing divergence in guidance solutions as to evolution of upper level flow...leading to some spread into how far back west to throw clouds/showers (along the potential for afternoon shower development across northwest Lower). A lot of nuisance stuff to be sure but just the type of weak nonsense that turns what was a dry forecast into something potentially more pessimistic. .LONG TERM...(Tuesday night through Saturday) Issued at 401 PM EDT Sat Jun 3 2017 High pressure settling over the region will bring quiet weather as we go into mid-week. Temperatures expected to be near to slightly above normal. A possible shortwave late in the week could bring some shower chances, but there is a good deal of model divergence in the strength of this wave and things could remain dry though the weekend. Currently, the dry solution has a bit more support, but will leave the low chance PoPs towards the end of the period for now. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 731 PM EDT Sat Jun 3 2017 Challenging forecast heading through the next several hours as upstream convective complex makes a run into the area. Simple radar trends and other observational data suggests deepest convection will pass by to our west and southwest, leaving lighter showers and embedded thunderstorms to make their way across the taf sites this evening through the early morning hours. Cloud bases expected to remain rather elevated, perhaps dropping into MVFR range under any heavier showers. Showers likely to exit during the early morning, with hints of a brief window of low overcast and mist forming, especially near KPLN. Low level instability increases again on Sunday, lifting any low overcast to a growing cu field and perhaps forcing the development of more showers. Wind shear expected across much of the area tonight as low level jet passes. Otherwise, mostly light surface winds expected. Will need to watch for brief gusty winds tonight with any thunderstorm activity. && .MARINE... Issued at 401 PM EDT Sat Jun 3 2017 Southwest winds will become a bit gusty tonight as a round of showers and embedded thunderstorms moves across the area. Conditions should remain under small craft advisory however. This does not include possible isolated stronger wind gusts in thunderstorms late tonight/early Sunday. Winds turn more northwesterly on Sunday and eventually northerly Sunday night while remaining fairly light. && .APX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LH...NONE. LM...NONE.

An area of showers, with a few embedded thunderstorms, will move quickly southeast across the area through the early morning hours. An isolated severe thunderstorm is possible, with damaging wind gusts the primary concern. The greatest threat for any severe storms will be along and west of Interstate 75 in northwest lower Michigan between 10 pm and 1 am. .DAYS TWO THROUGH SEVEN...Sunday through Friday. There is a chance of thunderstorms Sunday afternoon and evening across northern Lower Michigan. There is a small risk for severe storms. .SPOTTER INFORMATION STATEMENT...
