.what has changed...
no significant changes with this update as tranquil weather
continues through most of this upcoming week.

&&

.key messages...
1) dry weather with pleasant temperatures much of the week. a
gradual warming trend begins on wednesday.

2) scattered showers and thunderstorms are expected over the
weekend.

key message 1...
high pressure builds southeast across the great lakes through
wednesday before departing to the southeast and off the atlantic
coast late in the week and into the weekend. quiet weather
expected, with a warming trend starting wednesday, with highs
in the 70s through mid week warming to the 80s thursday onward.

key message 2...
model guidance has continued to trend slower, and drier for
friday, though we still have a 10-15% pop for friday afternoon,
so can`t rule out an isolated shower or storm. continued
building of warm, moist air with southwest flow along with weak
forcing from a southward advancing cold front will contribute to
higher likelihood in scattered showers and thunderstorms on
saturday and sunday (30-50% pop currently). the risk for
flooding and severe weather is very low but heavy downpours are
possible within thunderstorms.

&&

.aviation /06z monday through friday/...
vfr conditions persist through the taf period under high
pressure that remains across the great lakes region. light and
variable flow expected through monday afternoon. northerly to
northeasterly winds increase to 5-8 knots with locally higher
winds 8-12 knots expected in a lake breeze at kcle and keri
monday afternoon.

outlook...vfr expected through friday.

&&

.marine...
mainly quiet marine conditions are expected through the week as
high pressure persists across the region. could see a few brief
periods of 2 to perhaps 3-foot waves as the lake breeze enhances
the northeast gradient winds, especially later today and on
tuesday afternoon. otherwise, overall flow will generally remain
light through much of the week, before shifting to the southwest
late friday into saturday, 10 to 15 knots.

axis of very weak lift has edged into far sw parts of the area with
earlier returns having fallen apart as it encountered the very dry
low levels. slightly better setup upstream from chicago nw where
some sprinkles/very light showers are occurring from a mid level
deck. have left the inherited mention of sprinkles into mon
morning in sw areas, but toned down to slgt chc for now. these
should quickly end during the morning with temps back well into
the 70s for the afternoon.

outside of this, a tranquil and seasonably warm forecast is still in
store until the upper level flow begins to flatten and sfc high
pressure shifts east to allow for increasing warmth and moisture,
along with chances for showers and storms for the weekend.

light winds and vfr conditions will dominate. a weak mid level
trough may allow for a brief visit of mid level clouds to ksbn,
but it should remain dry.

significant mid to upper level trough axis along the eastern flank
of the omega block will dig/pivot across lake huron and lower
michigan today. a weak kinematic impulse or very modest jetlet
feature from an atypical northeast direction will result in very
deep isentropic downglide/subsidence event and drive a dewpoint
front first through the thumb by 18z and through the remainder of
the forecast area by 00z this evening. gusty northeast winds are
again expected behind the front with 15 to 30 mph possible (greatest
winds over the water). weak height falls associated with the trough
and a thermal low response will likely pool some modest surface
based thetae ahead of the dry front. quite possible that some high
based boundary layer cloud will be observed over portions of lower
michigan particularly west of us 23 this afternoon. loss of daytime
heating and dry air advection will choke off any cloud and cause it
to dissipate after 23z.

greater upper level jet energy to the east of the blocking pattern
is expected to result in a tugging or morphing of the geopotential
heights into a more rex like configuration for tuesday and
wednesday. there has been consistency amongst the models that
greatest ridging aloft will fold and build directly over southeast
michigan for tuesday and wednesday. again the naefs dataset supports
99.5th percentile or climatological maximum for geopotential heights
for a deep portion of the column from 1000mb up to 500mb. the
increased height thickness leads to warming with highs near 80
degrees tuesday with lower 80s possible on wednesday.

a consensus of global deterministic guidance suggests that moisture
collected along the upstream edge of the blocking will finally
release into the great lakes region and michigan by friday and
saturday. very low confidence exists on the most favored time period
for precipitation onset at the end of the week. the main reason for
the low confidence is because of likely mcs and/or latent heating
dynamics. do not have any confidence the models have the impact of
the latent heating correct. lots of uncertainty also exists on
duration of precipitation chances as the latest ecmwf solutions
suggests the possibility of a stalling baroclinic zone developing
right through next weekend. the main narrative is much warmer and
much more humid next weekend.

.marine...

flow has started organizing out of the northeast this morning as a
weak backdoor cold front drops across the area. generally relaxed
gradient caps wind gusts around 20 knots for most of the waters,
although gusts to 25 knots are expected for inner saginaw bay where
flow aligns with the fetch of the bay. favorable marine conditions
and dry weather expected through most of the week as high pressure
builds overhead. extended stretch of dry weather comes to an end
friday-this weekend as the high pressure pattern breaks down.

the surface layer has decoupled early tonight - allowing the surface
winds to nearly vanish. the only clouds are a thicker cirrus
filament along the edge of the high cloud shield lingering over the
southern terminals, which will remain so through most of the night.

main story for monday will be the boost the surface high gets from
the big cold water of the great lakes. a rather aggressive
northeast flow release is expected off of lake huron, starting
midday downstream of saginaw bay and by mid-afternoon farther inland
at fnt and ptk, then eventually det as the release works south into
the st clair basin. gusts will be prominent - approaching 25kts at
mbs and a little tamer farther away from lake huron. the lake erie
influence will not be as pronounced - however, still expecting a
late afternoon release affecting dtw/yip - but not with the vigor
seen farther north. the lake erie boundary may also excite some
high based cumulus for a few hours, but will remain above 5kft.

d21/dtw convection...no thunderstorms through monday.

dtw threshold probabilities...

* none.
