.DISCUSSION...
The core of the upper low responsible for showers and thunderstorms
early this morning will pass overhead during the peak heating period
today. Strong 295-310K system relative fgen and strong deep layer
deformation will fuel a band of moderate to locally heavy showers
along/north of the surface low track. Instability will be sufficient
to generate thunderstorms and small hail, but severe hail appears
quite unlikely attm as better instability will be well south and
east. Greater concern will be the potential for localized flooding
given decent pwats of around 1.6"+ and strong mesoscale forcing. The
threat will depend exactly where the band sets up. Attm,
increasing consensus on the heaviest rain falling roughly along a
Saginaw-Lapeer-Mt. Clemens, but will ultimately be a nowcasting
issue, particularly as consequences of convection play into subtle
differences in outcomes for the low track. Rain totals could easily
exceed an inch on a local basis with peak intensity 12-18z before
forcing shifts south and east of the area. Precip, clouds, and
developing northerly flow will keep highs tempered in the low to mid
70s for most areas.
Significant ridge over the Southwest US will amplify north and
eastward in advance of west coast height falls. Increasing deep
layer subsidence will favor average temperatures and sunny skies
under high pressure through the weekend. Active northern stream will
peel a ribbon of warm air off of the southwestern heat ridge early
next week, setting the stage for temperatures to potentially rise
well into the 90s as h85 temperatures exceed 20C.
&&
.MARINE...
Widespead showers with a chance of thunderstorms will exist for much
of today with the low pressure system only slow to peel out of the
state. Winds will quickly turn to the northeast this morning as the
low pressure center gathers directly over southeastern Michigan and
digs into Lake Erie. The proximity of the sourthern basin of Lake
Huron including Saginaw Bay to the surface low means a period of
stronger northeast winds will funnel down the bay and be felt
onshore. A small craft advisory remains in effect. Winds and waves
will decrease during the late evening today as Canadian high
pressure builds into the area. Extremely quiet marine conditions
are expected Friday and through the upcoming summer weekend.
&&
.HYDROLOGY...
Widespread showers and a chance of thunderstorms are expected today
across southeastern Michigan. Basin wide averages of .50 to 1.00
inches is possible particularly in and along a path from the mouth
of the Saginaw River southeast to the north shore of Lake St Clair.
Localized flooding remains a possibility today particularly for
those areas that are impacted by slow moving or stalling
thunderstorms.

.PREV DISCUSSION...
Issued at 1247 AM EDT Thu Jun 16 2016
AVIATION...
A cluster of showers and strong thunderstorms will lead surface low
pressure into SE Michigan during the early morning. A burst of IFR
restriction in the heaviest rainfall will give way to a more general
MVFR visibility in lingering showers and fog with lower ceiling
expanding as the surface low moves into the region. There is
considerable coverage of IFR ceiling over northern lower Michigan
and Wisconsin that will likely slide into the area as the surface
low gets closer to the Ohio border toward sunrise and then last
through the morning. North to south improvement will occur over the
terminal corridor as the system exits the area during the afternoon
into Thursday evening.
For DTW... The band of showers and thunderstorms over western lower
Michigan at press time is expected to be maintained by the warm
front running from GRR to near DTW. A brief shot of IFR in the
heaviest rainfall will give way to mainly MVFR/IFR ceiling as the
surface low moves almost directly overhead during the morning.
//DTW Threshold Probabilities...
* High for ceiling 5000 ft or less toward sunrise through today.
* Moderate for thunderstorms during the night (07 to 11Z).
