The episode as NWS DTX wrote it up.
Thunderstorms moving through southern Lake Huron produced wind gusts to 35 knots.
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 Detroit, MI wrote its last area forecast discussion before the first event at Aug 23, 6:26 PM EST, 1 hour 4 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Detroit/Pontiac MI 726 PM EDT Sat Aug 23 2025 .KEY MESSAGES... - Fall-like weather arrives to end the weekend and persists right into Wednesday with highs in the upper 60s to mid 70s and lows falling into the 40s early next week. - Chance for brief light showers tomorrow and Monday, otherwise dry for the mid week period. && .AVIATION... A cold front continues to push southeast across the terminals this evening. It will take a few more hours until clearing, thus expect some additional thunderstorm development along and ahead of the boundary, mainly for the Metro terminals (DTW/DET/YIP). Storms to the northeast and southwest may just miss PTK, but did add a VCTS and then TEMPO for thunder through 01Z. Veering wind shift has already shown its self in upstream obs (FNT/MBS) with lingering westerly gustiness. Drier conditions prevail in the wake of the front with the southern sites eventually turning westerly, too. Post- frontal subsidence will lead to the thinning of clouds, but model data suggests FEW-SCT low VFR cloud may linger overnight. The surface gradient relaxes with time into Sunday morning out of the northwest quadrant. Boundary-layer diurnal cloud response anticipated by late morning Sunday with a stray shower possible north of PTK into the midday time-frame. For DTW/D21 Convection...A couple passes from upstream thunderstorms remains possible until about 02Z this evening. THRESHOLD PROBABILITIES... * Low to medium in thunder through 02Z this evening. * Low in ceilings at or below 5000 feet, until after 14Z Sunday (medium). && .PREV DISCUSSION... Issued at 255 PM EDT Sat Aug 23 2025 DISCUSSION... Large upper level low/trough over Ontario will be in no hurry to exit east, leading to below normal temperatures to end the weekend through early next week. Cold front tracking through southeast Michigan late this afternoon will offer up the potential of isolated- scattered thunderstorms as the strong cap around 750 MB seen on the 12z DTX sounding is eroded, leading to skinny capes aoa 1500+ J/kg. 0-6 KM bulk shear around 35 knots suggest an isolated cell could be strong to potentially severe (less than 5%) if can get some enhanced low level convergence with any marine layer interaction across the Eastern Thumb region. Otherwise, unidirectional low level southwest flow will make it difficult to sustain updrafts. The front looks to be clearing all of southeast Michigan by 2z, with good drying and low level cold advection kicking in. 850 MB temps to drop below 10 C by Sunday morning, and under 7 C by Monday morning as a shortwave currently over Central Canada provides a reinforcing shot of cold air and amplifying the longwave trough over the eastern two thirds of North America. With some moisture flux from the warm waters of the Great Lakes, steepening low level lapse rates will likely be sufficient to generate some light shower activity Sunday and Monday as modest capes (100 J/kg) are embedded around the freezing level. EQL levels look to mostly come up short of -20 C, with main threat of thunder over the waters of Lake Huron. The heart of the cold Canadian air will be in place on Tuesday, with temps starting out in the 40s to start the days on both Tuesday and Wednesday. A modest warmup then takes place Wednesday-Friday with marginal height rises and low level southwest flow allowing 850 MB temps to reach close to 10 C, allowing temps to at least get back to normal values. MARINE... A low pressure system tracking east across James Bay will drag a cold front through the central Great Lakes this evening, and perhaps into the early overnight hours. Scattered shower and thunderstorm development is expected ahead of the boundary, but some uncertainty remains regarding the degree of coverage. Cannot rule out a couple stronger storms capable of generating locally higher winds and/or waves, thus some MWSs or SMWs may be needed. Cooler conditions settle in behind the front for Sunday, and at least through the first half of next week. This leads to better mixing potential amidst stronger flow aloft, therefore gusts could approach Small Craft Advisory conditions at times. Also monitoring low-end gust to gale potential for the northern Huron basin, mainly for Monday afternoon. Additional chances exist for shower/storm development Sunday and Monday with isolated waterspouts possible, mainly over portions of Lake Huron. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...None. Lake Huron...None. Lake St Clair...None. Michigan waters of Lake Erie...None. && AVIATION.....KGK DISCUSSION...SF MARINE.......KGK You can obtain your latest National Weather Service forecasts online at www.weather.gov/detroit.
