Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
317 PM EDT Tue Jun 16 2026
.KEY MESSAGES...
- Numerous thunderstorms are likely this afternoon and early
evening. Isolated storms may be strong to severe.
- Widespread rain and thunderstorms are expected Wednesday evening
and Wednesday night. Heavy rainfall is likely which may lead to
localized flooding, especially in urban areas. The potential also
exists for severe weather, mainly south of I-94.
- Slightly below normal temperatures are expected through the week
and next weekend.
&&
.DISCUSSION...
Active weather pattern the next two days with multiple rounds of
thunderstorms likely and potential for flooding rains, especially
Wednesday evening.
A look at the visible satellite early this afternoon shows the
system responsible over northern WI with the attendant cold front
extending to the south while a prefrontal fgen band exists over
eastern Lake MI producing showers. Locally over SE MI some high
based showers initiated early with the lack of a cap but little
morning CAPE and shear prevented much from developing. Heading into
the afternoon, a 30 knot low level jet will lift ahead of the
prefrontal band while a pocket of 500mb vorticity pivots around
reaching southern MI at the same time. This mostly seems to come
together over SW MI, hence SPC upgraded that region to a Slight Risk
while leaving part of SE MI in a Marginal Risk. SBCAPE is forecast
to top out around 500 J/kg with some bulk shear around 30 knots.
We'll have to see how upstream convection can hold together as it
approaches for increased severe chances. Dry low levels showing up
in the soundings as an inverted V, supporting the higher bases
convection will also support wind gusts of 40 to 60 mph as the most
probable severe threat this afternoon mainly from 20-00Z.
Wednesday still garners much attention with the unseasonably strong
low driving through the region. Some changes/questions of note to
the setup in terms of location of the low/occlusion which will
dictate severe chances in SE MI. Models still support a strong mid
level trough over MN/WI with a sub 990mb surface low under it. A
strong mid level wave will rotate through the base of the trough
across southern Lake MI while a very strong 60+ knot low level jet
racing northward just ahead of the wave through IL and into southern
MI just before Wednesday evening (around 00Z Thursday). The strong
lift ahead of the surface low will cause the system to occlude and
refocus a center over southern MI or northern IN. At this point,
most of the support is to push it east near the state line. A
portion of the low looks to get rotated up through the Thumb, while
a potential MCS diving E-SE helps drive the instability axis
southward, keeping the bulk out of SE MI. Strong lift with
impressive southwesterly moisture advection will bring PWATs around
2 inches into SE MI on the lead isentropic arm, with the low and
associated thunderstorms passing through mainly in the 21-06Z
window. Severe weather chances remain limited as we expect the bulk
of the instability and surface features to remain to our south. SPC
Day2 outlook has remained relatively unchanged focusing on the
better setup south of the border. There remains a window around 00-
04Z when a narrow wedge of instability slips north through the area
which would be our best chance for severe storms. Main threat will
occur mainly south of I-94 but location will be adjusted as we see
where the surface boundaries set up.
Confidence in flood risk remains elevated Wednesday afternoon into
the overnight. WPC Day2 ERO continues to include all of SE MI in a
Slight Risk for flooding. The wealth of moisture, strong fgen and
EPV, with strong deformation developing just north of the low
center, should produce a wide swath of heavy rain across portions of
SE MI. Highest totals should occur close to the Ohio Border with
decreasing amounts heading north. As we get deeper into the suite of
CAMs, precip totals have had a slight downward trend, possibly
owning to the shorter duration with such a fast moving system.
Regardless, confidence remains fairly high for a swath of 1 to 2
inch rainfall totals, with locally higher amounts exceeding 3 inches
possible.
We remain in the broad upper level trough on Thursday with the
remnant surface low from MN/WI tracking across central MI Thursday
afternoon. Steepening low level lapse rates look to be able to
produce a round of low topped showers early Thursday. Mid level
trough feature should pass to the east, ending the support for
showers overnight but could see another window of diurnally forced
showers on Friday, more limited in coverage.
&&
.MARINE...
A low pressure system and its attendant cold front gradually work
through the central Great Lakes from west to east, supporting
continued showers and thunderstorms into the evening and early
overnight hours. An isolated threat for hazardous wind gusts and
large hail remains. A brief break in activity emerges during the
daylight hours Wednesday as ridging aloft quickly passes through. A
secondary stronger low pressure system follows in quick succession
late Wednesday into Thursday. More intense convection is possible
with this system, capable of damaging winds, and to a lesser extent,
waterspouts and large hail. Prevailing southwesterly gradient winds
accompanying the low climb above 25 knots, once the center
approaches Lake Huron late Wednesday night. This eventually backs
flow northwesterly, based on the northeast trajectory of the system
across the Huron basin. Gusts to gales remain possible, mainly for
the southern waterways, as the strongest LLJ winds of 40-50 knots
pass through the lowest 3 kft. Shallow mixing profiles appear to
exhibit only meager growth, maintaining uncertainty with the
potential/duration of gales. Opted to forego a Gale Watch for Lake
St. Clair and western Erie, but will reevaluate during the evening
update. Also, cannot completely rule out gales extending into
southern Lake Huron, too. Post-frontal winds decline a bit and
organize out of the west-northwest on Thursday, remaining so through
at least Saturday. Additional chances exist for showers and a few
thunderstorms over the weekend as cyclonic flow persists overhead.
&&
.HYDROLOGY...
Numerous showers and thunderstorms are forecast this afternoon and
evening. Most areas will receive a quarter inch or less of rainfall,
but training of storms over the same areas will lead to totals
nearing an inch. Flooding is not likely today.
A seasonably strong low pressure system will then arrive late
Wednesday, producing widespread rainfall with numerous heavy
thunderstorms through Wednesday night. Rainfall totals ranging
between 1 and 2 inches are likely for much of SE MI, and isolated
areas may receive over 3 inches. Most of this rainfall is expected
to occur in 6 hours or less, currently centered between 8pm and 2am.
This rainfall may pose a flash flooding threat, mainly in urban
areas, and rises on rivers and streams can be expected.

.PREV DISCUSSION...
Issued at 131 PM EDT Tue Jun 16 2026
AVIATION...
Initial 700-600mb thetae/warm air advection was sufficient to
generate numerous high based showers and thunderstorms across much
of the central sections of the forecast area early this afternoon.
With little convective inhibition, additional outflow boundaries
could provide additional forcing for more development the next
couple of hours. Additional thunderstorm redevelopment is
anticipated along a cold front sometime in the 21-02z time window.
There is a better potential for strong to severe thunderstorms this
evening. MVFR ceilings are expected this evening and tonight with
high ambient moisture from todays rainfall and radiative cooling.
Clouds scatter with diurnal heating Wednesday with thunderstorm
activity holding off until Wednesday evening.
D21/DTW Convection...There is a chance for thunderstorms to persist
this afternoon in the airspace with a more organized line of
thunderstorm activity expected to approach D21 between 22-02z.
DTW THRESHOLD PROBABILITIES...
* Moderate for ceiling at or below 5000 ft this afternoon.
* High for thunderstorms this evening.
