The radar
The NCL Michigan radar (KAPX), 105 km from the middle of the area, began a volume at 03:55 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Alpena, MI (KAPX), launched 00:00Z, 3.9 hours before the alert went out and 98 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

.DISCUSSION...
Issued at 231 PM EDT Wed Jul 1 2026
Strong upper ridge across the Great Lakes will gradually
flatten through the end of the week as several shortwaves and
strengthening westerlies slowly suppress the highest heights. A
quasi-stationary boundary snaked across northern Michigan
currently will also sink southward with time, which may push the
shower/storm focus further south, as well as providing at least
a little relief from the 70F+ dewpoints. Convective evolution
from day to day will remain challenging with low predictability.
Additional showers/storms likely tonight with additional
shortwave energy riding along an elongated low level theta-e
gradient draped across parts of Wisconsin into northern
Michigan. Low confidence in the details, as convective evolution
will be driven largely by mesoscale processes and residual
outflows from earlier convection. Plenty of moisture and
instability and severe storms will remain possible with large
hail and damaging winds. The main focus of showers/storms may
shift slightly south on Thursday with the gradient of deepest
moisture/instability. Severe storms possible once again.
Stronger forcing with a more defined shortwave arrives for the end
of the week with potentially greater coverage of showers/storms for
later Friday into Friday night. Organized convection certainly a
possibility during this timeframe with plenty of instabilty and
shear. Locally heavy rain also possible. Unsettled weather
continues into the holiday weekend with more shower/storm
chances. Temperatures should be more comfortable with highs
generally in the 80s and dewpoints in the 60s.
We may fall short of heat advisory criteria in some areas on
Thursday with slightly lower dewpoints. But heat indices still
likely 90-100F in many areas (possibly 100-105 southeast
areas). So will let heat advisory continue.
&&
.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1127 PM EDT Wed Jul 1 2026
Another challenging taf period with very low confidence in
convective evolution. Overall, mainly VFR conditions are expected
with just some higher based cumulus and some passing convective
blowoff cirrus. Again, will simply need to monitor radar trends for
specific impacts and timing of any activity into our taf locations.
Future amendments more than anticipated. Light winds this morning do
become bit gusty out of the southwest and west later this morning
and afternoon.
