Update
As of 950 am edt... Current forecast on track with just a few tweaks
based on latest trends in hi-res guidance and cloud cover. Dry day
through at least the evening hours is still expected for most, with
the exception being lenawee and monroe counties where initial band of
showers, possible thunder may arc into this area between 5-8pm on
leading edge of theta-e gradient warm front. Did bump high
temperatures down a degree (still lower 80s) across the board with
slightly thicker high clouds working in this morning. Rest of
forecast remains on track at this time.

aviation...

any lingering shallow fog will lift through the mid morning period,
leavingVFR conditions through the duration of the daylight hours.

A scattered to perhaps briefly broken coverage of higher based
diurnal CU will exist beneath thickening cirrus during this time.

Winds below 10 knots prevailing from the southeast. An
approaching low pressure system will provide an influx of deeper
moisture tonight and Tuesday. This will bring a corresponding
reduction in ceiling heights with increasing rain potential mainly
after midnight. MVFR restrictions become increasingly likely in
widespread rainfall Tuesday morning, with the possibility for a
period of ifr. Potential will exist for embedded thunderstorms
through this time, but confidence in occurrence at any particularly
time remains too low to include at this stage.

For dtw... Some diurnal CU expected today, but of generally limited
coverage. Steady reduction in CIGS expected early tonight as rain
arrives. Chance of thunderstorms tonight too low to include at this
time.

Dtw threshold probabilities...

* low for ceiling below 5000 ft prior to 00z. Moderate for ceiling
to fall below 5000 ft this evening, then high after midnight.

discussion...

elevated low level moisture remains over the area characterized by
dewpoints in the low to mid 60s and some added surface moisture from
yesterday's rainfall. Light winds and a period of mostly clear skies
through the early part of the night has allowed the opportunity for
patchy fog to develop this morning across parts of southeast
michigan. However, increasing mid to high clouds will keep coverage
area and visibility reduction lower than what we have experienced the
past couple days.

Satellite images early this morning show a closed upper low pressure
system becoming well organized across the central plains. This
system will drift across northern missouri towards the southern end
of lake michigan throughout today into tomorrow morning. Strong
northward moisture transport within the warm conveyor belt will bring
likely rainfall chances for southeast michigan by tonight. Lead edge
of the moisture looks to arrive this later evening riding along a
warm front being drawn northward into lower michigan. Some low
chances for precipitation may arise during the day associated with
any lake boundaries, however moisture quality decreases slightly
prior arrival of the leading edge moisture. Expect bulk of
precipitation to begin closer to midnight tonight with greatest
height falls and moisture arriving in conjunction with the low level
jet ramping up. Precipitable water values associated with this system
will be quite high pushing up to around the 2.00 inch mark.

Unfavorable diurnal timing will limit greater convective potential
and higher rainfall totals, but still anticipate a weakly unstable
profile. This will support waves of precipitation ultimately
resulting in a widespread soaking rain overnight into tomorrow
morning.

The mid level wave will begin to open up by tomorrow morning with the
surface low tracking through central lower michigan. High moisture
remains over michigan keeping higher precipitation chances in the
forecast for Tuesday. A cold front will push through southeast
michigan later in the day with more favorable diurnal timing this
time around, though higher cloud cover may limit greater instability
from being established during the day. There will still be a chance
for some embedded thunderstorm development within lingering activity.

Front should push through by late Tuesday evening, which will also
bring an end to the precipitation as the system exits to the east and
upper ridging moves overhead.

Weak upper ridging and high pressure will take hold of the great
lakes mid week and continue into the later half of the week.

Temperatures will begin to rebound back into the upper 70s and low
mid 80s for Thursday and Friday. A shortwave is forecast to move
into the western great lakes Friday afternoon and will result in
increasing rain chances for Friday night as the trough axis crosses
the central great lakes. Mid level high pressure sets up across the
southeastern us and brings more zonal flow over michigan to close
out the weekend.

Marine...

a modest southeasterly wind will prevail today, as the region
remains between high pressure exiting to the east and an organizing
low pressure system over the mid mississippi valley. This will
maintain favorable boating conditions with limited wave action. The
seasonably strong system will lift into the great lakes tonight and
Tuesday. This will lead to a period of unsettled conditions with
widespread rainfall and a chance of thunderstorms during this time.

A moderate south to southeast wind in advance of this system will
turn northwesterly and strengthen in its wake late Tuesday and
Tuesday night. Gusts 25 to 30 knots expected over the lake huron
Tuesday night, with the potential to briefly approach gales. Small
craft conditions likely for the nearshore waters and saginaw bay
under increasing wave heights and gusty conditions. Winds and waves
gradually decrease into Wednesday as high pressure slowly builds
into the region.

Hydrology...

a seasonably strong storm system will sweep across the region
tonight and Tuesday. Widespread rainfall is expected with totals
exceeding an inch in many locations. Locally higher amounts will be
possible with any thunderstorm activity. While ponding of water will
be prevalent, a widespread flood threat is not anticipated with this
activity as local watersheds will have the capacity to absorb and
disperse.

Dtx watches warnings advisories
Mi... None.

Lake huron... None.

Lake st clair... None.
