What happened

The episode as NWS DTX wrote it up.

A large and deep low pressure system (for mid-May standards) over the Upper Mississippi River Valley spawned severe thunderstorms, including tornadoes. An intense line of thunderstorms tracked across Lake Michigan during the evening of May 15th. This line produced localized wind gusts of 55-75 MPH over southwest lower Michigan, along with several large hail reports (up to 1.75 inches) and several weak tornadoes. As the line moved into southeast Michigan just before midnight, the moderate instability from the daytime heating (max temps reached into lower 80s) began to wane, and the air mass near the surface began to stabilize. This caused the storms to slowly weaken as they tracked through southeast Michigan during the early morning hours of Friday (May 16th). Despite this, four tornadoes were able to develop across parts of Saginaw, Genesee, and Livingston counties, with isolated to scattered severe thunderstorms across the rest of the area. Over all, most of the Detroit Metro area was spared and saw limited wind damage, as DTE energy outages peaked just under 10,000 customers.

What forecasters said that day

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 May 15, 6:03 PM EST, 4 hours 43 minutes earlier. Its key messages:

Clusters of severe thundestorms expected 10pm and 3am tonight. Large hail and damaging winds are the main threats, with a low chance of a few tornadoes.
Warm again on Friday with another round of showers and thunderstorms developing late Friday evening/Friday night. Some of these storms will also be strong to marginally severe.
Cooler conditions this weekend, with westerly wind gusts 30-40 mph on Saturday.

.KEY MESSAGES...

- Clusters of severe thundestorms expected 10pm and 3am tonight.
  Large hail and damaging winds are the main threats, with a low
  chance of a few tornadoes.

- Warm again on Friday with another round of showers and
  thunderstorms developing late Friday evening/Friday night. Some of
  these storms will also be strong to marginally severe.

- Cooler conditions this weekend, with westerly wind gusts 30-40 mph
  on Saturday.

.AVIATION...

The surface warm front is inbound from the Ohio border region this
evening marked by a southerly wind shift and an uptick in T/Td,
along with broken coverage of invigorated cumulus. Elevated portions
of the warm front supported a few late afternoon showers near DTW
which have since dissipated. The front now outlines the northern
fringe of the instability axis and is expected to merge with lake
breeze boundaries while moving toward the I69 corridor by midnight
as the storm complex arrives from the west. The storms will affect
all terminals mainly from 04-06Z while the strongest activity is
favored to occur along and south of the warm front mainly from PTK
and through the DTW corridor. All severe thunderstorm hazards are
possible but damaging wind is the primary hazard given the upscale
growth of storms into linear segments/clusters this far east. VFR
conditions move in post cold front late tonight through Friday as
surface Td drops back into the 50s as a measure of decreased
potential for low clouds and shallow cumulus Friday afternoon.

For DTW/D21 Convection... A line of strong to severe thunderstorms
is on schedule to reach the DTW terminal area during the 04-06Z time
window.

THRESHOLD PROBABILITIES...

* High for ceiling 5000 feet or less toward midnight through sunrise
  the low through Friday.

* High for thunderstorms tonight mainly 04-06Z.

.PREV DISCUSSION...
Issued at 307 PM EDT Thu May 15 2025

DISCUSSION...

Moderate instability has built up across southeast Michigan with
MLcapes aoa 1500 J/kg with sbcapes 2000-3000 J/kg as of 18z. None-
the-less, just a modest CU field around as warm/dry mid levels cap
activity for now. Severe thunderstorm chances will begin to increase
this evening with arrival of the height falls and increasing wind
fields, but bulk of thunderstorm activity looks to be impacting
southeast Michigan around midnight. With the southeast winds, a
stabilizing marine influence off of Lake Erie/Lake St. Clair looks
to be coming into play, but an enhanced low level
temperature/instability gradient will set up across the western half
of the CWA (along/west of US-23). These locations stand the best
chance of activity remaining surface based, and thus the greatest
potential for damaging wind gusts with a chance of tornadoes as 0-1
KM bulk shear resides in the 25 to 30 knot range.  With increasing
southwest low level jet (50+ knots) and steep mid level lapses,
large hail will be a concern as well, as cape (1500+ J/kg) is
maximized around the freezing level to -20 C.  Progressive nature of
activity will limit flood threat, but urban areas (Wayne county) are
not completely out of the woods, as strong to severe thunderstorms
could drop a quick 1.5-2 inches in an hour in localized spots, as PW
values peak around 1.75 inches. Majority of hi-res solutions all
generally indicating a broken to near solid line of
showers/thunderstorms rolling through, ending 2-4 AM.

With the large 500 MB low center still back across the Western Great
Lakes on Friday, deep southwest flow will promote another warm day,
as 850 MB temps around 15 C will be supportive of high temperatures
in the low to mid 80s. A spoke of energy/shortwave looks to be
rotating around and tracking through southeast Michigan around
midnight once again. Confidence is high in another round of showers
and thunderstorms developing late Friday evening/night as the healthy
cold front tracks through. Although instability parameters are less
than this evening, wind fields/bulk shear and capes in 1000-2000 J/kg
range seem supportive of at least a marginal risk of severe storms.

Cooler and breezy on Saturday, as surface low (992-994 MB) tracks
through the northern Great Lakes. Pretty good cold advection with
850 MB temps lowering into the mid single numbers. Steepening low
level lapse rates during the day generates some modest cape, which
may touch of isolated-scattered showers. Otherwise, local
probabilistic guidance suggests wind gusts of 30-40 MPH during the
day.

Weak shortwave riding for Sunday, but there is already another
shortwave/re-enforcing shot of cold air to track through the Great
Lakes region for Sunday night. Dry air and northwest confluent flow
looks to keep us dry to start the work week. Another large low
pressure system to develop over the Central Plains, but still
uncertainty with the magnitude and areal extent during the mid week
period, which will impact the timing of showers returning to
southeast Michigan.

MARINE...

Light E/SE flow continues across the region this afternoon-evening
though funneling down the Saginaw Bay has allowed for local
enhancement towards 15kts. A warm front tied to strong northern
Plains low pressure is currently lifting out of the Ohio Valley
towards the Great Lakes this afternoon. A line of strong/severe
thunderstorms is expected to develop over the western Great Lakes
and push through our area late evening-early tonight (~10p-3a). All
hazards (strong winds, hail, waterspouts) are in play though wind
gusts greater than 40kts and hail above a half inch are the main
threats. Southerly winds up to 15-20kts develop post front for
Friday as the low tracks over Lake Superior. This system then sweeps
a cold front through the central Great Lakes late Friday evening-
early Saturday night generating another line of showers and
thunderstorms- a few of which could be severe (wind and hail
hazards). Moderate west-southwest winds follow Saturday with the
strongest winds (20-30kts) expected over the southern half of the
region where the gradient is strongest. Small craft advisories are
likely needed for most if not all nearshore waters as a result. Low
fully departs Sunday shifting winds to the northwest. Gusts peak
near 20kts during the day before weakening overnight as weak high
pressure slides overhead.
