At 225 pm edt, doppler radar indicated strong Thunderstorms, capable of producing winds to up 30 knots. These Thunderstorms were located along a line extending from 22 nm northwest of new baltimore to 11 nm northwest of the ambassador bridge to 13 nm west of elizabeth park marina, moving east at 25 knots. Locations impacted include...

Clair, algonac, metro beach metropark marina and wyandotte. Precautionary/preparedness actions... Mariners can expect gusty winds up to 30 knots, locally higher waves, and lightning strikes. Boaters should seek safe harbor immediately until these storms pass. This strong Thunderstorms will likely produce winds up to 30 knots, and could pose a serious hazard for boaters. A special marine warning may eventually be required when these storms reach the nearshore waters. Boaters should consider heading for shore before these storms arrive. && lat...lon 4289 8247 4261 8252 4255 8259 4254 8266 4237 8283 4232 8306 4223 8313 4221 8319 4233 8311 4239 8295 4266 8285 4272 8269 4270 8261 4264 8256 4265 8255 4301 8247 4340 8259 4344 8255 4343 8221

Aviation
Showers will work through all terminals this morning, but CIGS will
remain lowerVFR with just occasional MVFR vsbys in a few heavier
showers. This activity will end quickly in the 16z-17z time frame
with clouds slowly breaking up thereafter. Another rounds of showers
may occur late tonight as well in advance of an approaching cold
front. In the wake of this front, gusty southwest to west flow will
set up on Thursday.

For dtw... Showers with CIGS occasionally AOB 5kft expected this
morning. CIGS then slowly lifting and breaking up later today.

Southeast winds to turn southerly tonight.

Dtw threshold probabilities
* low confidence in thunderstorms impacting terminal this morning.

* medium confidence in cigs AOB 5000 feet this morning, low this
afternoon.

discussion...

showers and thunderstorms are moving into western michigan early
this morning within a ribbon of higher theta-e being driving
northward by a 60 knots low level jet. Modest elevated instability
and steep mid-level lapse rates will support scattered general
thunderstorms. Confidence is lower in coverage and intensity of
these showers and thunderstorms as they begin to move through
southeast michigan between 12-18z. This is due to relatively weak
isentropic ascent as it reaches southeast michigan and better
instability holding across northern in. The other factor is the
onset of mid level subsidence, which is limiting the deep layer
moisture to a degree. However, morning radar trends suggest a slight
increase in pops for the 12-15z period is warranted for at least the
western portions of the cwa.

Precipitation will move into the eastern portions of the CWA by
18z and gradually come to an end with the exception of the thumb
where some lingering precipitation may linger slightly longer into
the early afternoon. Above the surface will be southwest flow, which
will drive a warm front northward through michigan throughout today.

This will work towards driving the cool marine modified airmass out
of the area. The front will lift into northern lower michigan by this
evening, which will result in a gradient in high temperatures across
the cwa. Looks like upper 50s along the shoreline of the thumb and
mid upper 70s across the ohio border.

The dry slot of the plains system will then move over michigan
bringing a period of dry weather by this evening and overnight. A
front will then be pushed through michigan on Thursday by the
weakening low pressure system as it crosses over the northern great
lakes. This will bring chances during the morning hours for
convection to kick up ahead of the front. An increase in elevated
instability and steeper mid-level will bring the potential for
thunderstorms. Precipitation clears the area during the early
afternoon replaced with gusty and warm west winds in a well mixed
post frontal environment. Passing surface high and upper ridge keep
dry conditions through Thursday night as the surface front is pushed
south of michigan and stalls out across the ohio valley.

On Friday, the upper jet will be streaming across the intermountain
west and develop another surface low which will lift through the
northern plains as it undergoes cyclogenesis. This will draw the
aforementioned stalled boundary northward through michigan as a warm
front and bring another chance for showers and thunderstorms.

Precipitation chances continue late Friday night and through much of
Saturday with michigan residing between a low pressure across
southern ontario and a high pressure across the southeastern us.

This will send a corridor of high moisture into michigan with a
strengthening low level jet. Increasing instability and shear on
Saturday will bring the chance for another round of thunderstorms.

High pressure over the great lakes by Sunday afternoon will limit
precipitation chances to close out the weekend while slightly cooler
air settle over the region. High pressure with temperatures around
average look to hold into early next week.

Marine...

east to southeast flow will increase today as high pressure shifts
off to the east and a warm front begins to encroach from the south.

However, wind gusts are generally expected to stay under 25 knots
along the nearshore waters of lake huron with waves generally
peaking in the 2 to 4 foot range. Hence, small craft advisories will
not be issued. The small craft advisories for the michigan waters of
lake erie is continue as winds and waves will be slightly stronger
this morning.

Winds will become south to southwest late today into tonight ahead
of a cold front which will pass through the region on Thursday.

Gusts up to 25 knots are possible right along the shoreline areas of
the nearshore waters, but with low level stability over the open
waters will main gusts generally under 20 knots. A ridge of high
pressure will then settle through the area Thursday night and Friday
and bring light winds to all marine areas.

Hydrology...

scattered showers and a few thunderstorms will pass through
southeast michigan this morning and exit to the east early this
afternoon as a warm front lifts north. Basin average rainfall is
expected to average less than a quarter of an inch.

Increasing east-southeast flow associated with this warm front will
bring another period of flooding concerns along the shorelines of
lake st clair and western lake erie. Lakeshore flooding advisories
will remain in effect.

Dtx watches warnings advisories
Mi... Lakeshore flood advisory until 6 pm edt this evening for miz070-076.

Lakeshore flood advisory until 2 pm edt this afternoon for miz083.

Lake huron... None.
