The episode as NWS MQT wrote it up.
Several clusters of severe thunderstorms moved across south central Upper Michigan on the afternoon and evening of the 11th.
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 Marquette, MI wrote its last area forecast discussion before the first event at Jun 11, 5:38 AM CST, 6 hours 37 minutes earlier.
Area Forecast Discussion National Weather Service Marquette MI 738 AM EDT Sun Jun 11 2017 .SHORT TERM...(Today and tonight) Issued at 455 AM EDT SUN JUN 11 2017 WV imagery and RAP analysis indicated wsw mid/upper level flow from the plains into the nrn Great Lakes between a a trough over the nw CONUS and a ridge over the southeast. A shortwave into wrn SD along with strong low level inflow supported an expanding area of convection over cntrl SD. At the surface, a weak frontal boundary that moved through most of the cwa extended from ern Upper Michigan to se MN. Today into tonight, much of the forecast depends on the evolution of the SD MCS. The majority of higher res models suggest that upscale growth of the convection will occur with progressive MCS sliding through the upper MS valley into WI and into portions of Upper Michigan by the early to mid afternoon. Given the position of the frontal boundary and greater instability to the south, expect that the greatest chance for strong to severe convection with potential for damaging winds would be near the WI border. Nevertheless, confidence in the path of the stronger convection is still low with potential for severe convection/wind also across location along and south of M-28. In the wake, of the initial MCS, models suggest that strong theta-e advection with 35-40 knot sw 850 mb winds could fuel additional strong convection btwn 21z-03z. Much will depend on the affects, timing/scale of the earlier MCS. In addition heavy rain will be possible with PWAT values to 2 inches and a slower movement with the later round of convection. Rainfall amounts in the 2 to 3 inch range may be possible, mainly over the sw cwa. But with high uncertainty in the evolution/development, a flash flood watch was not issued at this time. Additional severe convection, including supercells and smaller scale bows may also be possible with 0-6km bulk shear of 50-60 knots and MUCAPE values to around 2k J/Kg. .LONG TERM...(Monday through Saturday) Issued at 420 AM EDT SUN JUN 11 2017 Plenty going on in the long term, but little in the way of confidence-inspiring signals for significant impacts during that time. A stationary boundary will be just S of the CWA Mon and Tue, with potential for convection each day (greatest potential along the WI border). Also see potential for some stronger storms along the WI border. Confidence in coverage, intensity and timing is low given nature of convection. The boundary pushes N into the area Tue night as an upper low moves from the Intermountain W into Manitoba. The highest precip potential of the long term will exist Tue night into Wed night Lowest precip potential in the long term is Thu into Fri as the upper low moves across northern Ontario. Upper level energy then looks to move into the region next weekend, bringing widespread precip potential back into the forecast. && .AVIATION...(For the 12Z TAFS through 12Z Monday morning) Issued at 737 AM EDT SUN JUN 11 2017 Conditions through the morning and early afternoon should stay VFR but will turn MVFR by this evening as rain and some thunderstorms move through the area. Depending on the path of the large convective system, a brief period of gusty winds may be possible at IWD and SAW this afternoon. IFR conditions are expected late Sun evening and overnight especially at CMX with developing easterly flow off Lk Superior. && .MARINE...(For the 4 AM Lake Superior forecast issuance) Issued at 455 AM EDT SUN JUN 11 2017 Winds are expected to be around 10 to 20 knots, before decreasing further to around 10 to 15 knots into early next week. By the middle of next week, winds are expected to increase to around 20 to 30 knots, before diminish to under 20 knots through the end of the week. This afternoon, a few severe storms will be possible across southern portions of Lake Superior with strong winds as the primary threat. Patchy dense fog could also develop, especially in the wake of areas of heavier rain. && .MQT WATCHES/WARNINGS/ADVISORIES... Upper Michigan... None. Lake Superior... None. Lake Michigan...
