The episode as NWS MQT wrote it up.
Severe thunderstorms forming along lake breeze boundaries caused wind damage over portions of Menominee County during the late afternoon of the 24th.
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 Jul 24, 1:49 PM CST, 1 hour 20 minutes earlier.
Area Forecast Discussion National Weather Service Marquette MI 349 PM EDT Wed Jul 24 2019 .SHORT TERM...(This evening through Thursday) Issued at 215 PM EDT WED JUL 24 2019 Upper air pattern consists of a deep 500 mb trough across the eastern half of the U.S. and a ridge across the Rockies and plains states. There is also a shortwave in the Canadian Rockies which heads east into the Canadian prairies on Thu. Still looks like there could be some lake breeze convection this afternoon with lake breeze convergence and kept in chance pops for this reason as airmass will be unstable enough to pop off some convection. With loss of heating in the evening, this should come to an end and then quiet weather for the rest of the forecast period. Overall, very little change was made to the going forecast. .LONG TERM...(Thursday night through Wednesday) Issued at 349 PM EDT WED JUL 24 2019 As the ridge shifts to the east and the pressure gradient begins to tighten Thursday evening, the long-advertised southerly to southwesterly gusts will begin to pick up. Given the good gradient flow, will likely see winds and gusts stay up all night and become blustery in the downslope areas around the Porkies, Marquette, and Grand Marais. Would not be surprised to see even 25 or 30 mph gusts overnight in these areas. This tight pressure gradient will persist and even increase Friday and Friday night as the closed upper low over the Canadian Prairies pushes into Ontario. Therefore, will continue to see blustery SW winds through this period and into Saturday morning. Even without good mixing, will probably still see gusts to 30+ mph Friday both on land and on the water. Some showers and storms look possible Thursday night into Friday as well with moisture convergence increasing and perhaps a subtle much lower amplitude mid-level short wave out ahead of the main system. However, with the stronger forcing slower to arrive, expect that these showers/storms will initially stay confined to the western arm of Lake Superior and then spread across the Keweenaw and western half of the U.P. early Friday. By Friday afternoon, could be one of those days where we get the sort of "effective dry line" between more mixing over the west and higher dews off Lake Michigan east become the focus for new development in the afternoon. Deep layer shear could be sufficient for storm organization over these areas once daytime heating allows enough instability to build, but overall the CAPE/shear combo looks to be on the low end wrt severe storm potential at this point. As the cold front pushes in from the west late Friday night and the gradient tightens further, the strongest winds may actually be Friday night, especially in the aforementioned downslpoe areas. The front then lingers near Lake Superior Saturday, could see some more showers and storms Saturday. Will also see gusts continue Saturday, though not as strong as Friday and Friday night. By Sunday, models want to bring another short wave up out of the Mississippi Valley, but are slower today then yesterday. Have kept chance POPs in Sunday but took them down a touch over NBM init. Moisture convergence increases further Sunday evening ahead of the next (stronger) cold front that right now should move across Upper Michigan Monday. Right now the timing does not look to support strong/severe storms as the front will pass through too early in the day, but being still several days out we'll want to continue to watch that. Once the front clears, Tuesday and Wednesday look dry with near normal high temps. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1223 PM EDT WED JUL 24 2019 VFR conditions will prevail over the next 24-hours. && .MARINE...(For the 4 PM Lake Superior forecast issuance) Issued at 215 PM EDT WED JUL 24 2019 Winds below 20 knots are expected through Thu. The approach of a surface trough Thursday night through Friday night, will result in winds becoming southwesterly and gusting upwards of 25 to 30 knots. These would be the strongest winds in the forecast period. && .MQT WATCHES/WARNINGS/ADVISORIES... Upper Michigan... None. Lake Superior... None. Lake Michigan...
