A few severe thunderstorms developed during the peak heating of the day, producing wind damage.
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 Jun 27, 1:28 PM EST, 44 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Detroit/Pontiac MI 228 PM EDT Fri Jun 27 2025 .KEY MESSAGES... - Thunderstorms are likely this afternoon and evening with a Slight Risk of severe weather between roughly 3 PM and 9 PM. A Severe Thunderstorm Watch is in effect for all counties until 9PM. - The primary hazards are damaging wind gusts in excess of 60 mph and torrential downpours. - Temperatures cool into the mid 80s Saturday before climbing back toward 90 degrees Sunday and Monday - Another cold front brings chances for showers and thunderstorms on Monday. && .AVIATION... A warm and humid airmass is place offering opportunities for showers and thunderstorms later today as instability builds into the peak of the diurnal cycle. A few showers are still possible ahead of the main line of storms, but VFR conditions are the expectation prior to its arrival while the cumulus field continues to thicken. Timing remains focused on a 21Z to 02Z window for the most robust convection which poses a torrential rainfall threat (IFR visibility) and strong to severe WSW gusts, potentially in excess of 50 knots. Ceilings could be slow to improve behind the front tonight, but expect gradual clearing in the lowest 15 kft AGL heading into Saturday morning. Gradient winds should be sufficient to preclude a nocturnal fog mention. Drier low-level environment expected through the first half of tomorrow with winds veering toward the WNW. For DTW/D21 Convection...Line of thunderstorms moving west to east becoming increasingly likely between 22Z and 02Z this evening. Cannot completely rule out an isolated storm this afternoon, prior to the main line. THRESHOLD PROBABILITIES... * High for thunderstorms this evening, but low prior to 22Z. * Moderate in ceilings at or below 5000 feet this afternoon and early tonight. && .PREV DISCUSSION... Issued at 1100 AM EDT Fri Jun 27 2025 UPDATE... Warm front lifting north has largely cleared the region this morning residing over the far northern Thumb into northern lower MI. Behind the front, the humid airmass has quickly expanded back across SE MI with surface obs showing surface Td's ranging between 70-74F. This sets the stage for another round of afternoon-evening thunderstorms as low pressure sliding over the northern Great Lakes drags a cold front toward lower MI by the latter half of today. Ample moisture allows daytime heating to build at least 1500-2000J/kg of SBCAPE by mid-afternoon (worth noting there are some CAM solutions that attempt to push near 2500 J/kg). Given the environment becoming uncapped by midday, some spotty convective initiation is possible over SE MI between 17-19Z which as always would muddle the progression later day convective trends. That said, bulk of CI still expected to occur over west MI during that timeframe in advance of the surface cold front. These storms then work into/across SE MI in some fashion of a broken line between roughly 3-9pm. Shear, or lack- thereof, will be the limiting factor for severe chances today as shown by the 27.12Z DTX RAOB sounding only depicting 15kts of effective inflow layer shear. Forecast soundings only advertise a modest uptick in shear magnitude by afternoon (increasing towards 25- 30kts- highest towards Thumb) though remaining predominately unidirectional. Damaging wind gusts remain the primary hazard today with any storm as steepening low level lapse rates (over 7.5 C/km) and DCAPE values near or above 1000J/kg support stronger downdrafts in any of the stronger convection. As noted in the overnight forecast discussion, while shear profiles are unidirectional, the lakeshore area's marine layer influence will be something to watch for localized rotation and potential for an isolated weak tornado. Torrential rainfall and localized flooding are also a threat under any storm today as PWATs hold between 1.5-2" (27.12Z DTX sounding showed 1.66") well within the 90th climo percentile. PREV DISCUSSION... Issued at 436 AM EDT Fri Jun 27 2025 DISCUSSION... A line of decaying elevated thunderstorms is tracking across lower Michigan this morning. Warming cloud top temperatures and decreased lightning activity over the past several hours indicate the weakening trend to this line, which will continue as it outpaces existing MUCAPE. Considering it will take some time for hydrometeors to completely evaporate, have increased PoPs substantially over the western half of the CWA through mid-morning. Humid conditions are already in place with most sites reporting dewpoints in the low 70s. Nocturnal convection will only add to this moisture to support primed boundary layer conditions for destabilization early this afternoon ahead of a cold front. Nearly all guidance brings high temperatures today to around 90 degrees, fueling about 1500-2000 J/kg MLCAPE. While not overly impressed by the hi-res models/HREF ensemble, there is a signal for a broken line of storms to develop between roughly 4pm-9pm this evening. Although shear profiles are modest (25-35 knots) and nearly parallel to storm motion, do think the rich theta-e airmass and pockets of dry air aloft will enhance downdrafts/cold pool development enough for damaging wind gusts in excess of 60 mph on a more widespread basis than what we have seen the past few days. Not expecting frequent rotation with these storms provided mostly unidirectional shear profiles, although a localized low end tornado risk does exist in the backed flow regime of the marine layer. This is especially true around the Thumb where 0-6km bulk shear is larger and in closer proximity to the cyclonic circulation of the surface low. All of this is encompassed within a Slight Risk for severe weather designated by SPC. The high moisture airmass will also bring potential for flooding, as discussed in the Hydrology section. The cold front successfully clears out the 70+ degree dewpoints into the Ohio Valley by Saturday morning, setting up a seasonable day across SE Michigan with high temperatures holding in the mid-80s. Strong subsidence takes hold and will maintain a capping inversion throughout the weekend to limit surface-based thunderstorm chances. The presence of a mid-level anticyclonic circulation in the 850- 700mb wind fields confirms the stable environment aloft. By Sunday, temperatures warm back toward the low 90s as the strong SE CONUS ridge makes its final push into lower Michigan. These warm temperatures and eventual moisture transport on Monday briefly bring warm and muggy conditions to SE Michigan. This airmass however will be short-lived as another cold front tracks through the region Monday night-Tuesday morning. The front itself will be the focus for additional thunderstorm chances, while the post-frontal airmass affords more seasonable conditions and a drier Canadian airmass. For reference, all three LREF ensemble mean PWATs are below 1.0 inch Tuesday-Wednesday of next week. MARINE... Another round of strong thunderstorms develops today as low pressure, and associated cold front tracks through the Central Great Lakes late in the day. Outside of thunderstorms, southwest winds look to remain below 20 knots. Light wind and favorable weather follows the passage of the cold front, with weak high pressure Saturday followed by another low pressure system entering the northern Great Lakes during Sunday through Sunday night. This system brings a stronger cold front into Lake Huron and Lower Michigan to start next week. HYDROLOGY... A cold front tracks across SE Michigan this evening, bringing a broken line of thunderstorms through the region between roughly 4 PM and 9 PM. These storms will occur in a warm and moisture-rich airmass which will be favorable for rainfall rates to exceed 1 inch per hour. Localized flooding will be possible, especially considering the several inches of rain that has already fallen in some spots this week. Typical urban, small stream, and flood prone areas are most at risk but also any location that has experienced repeated rounds of showers and thunderstorms. && .DTX WATCHES/WARNINGS/ADVISORIES...
