Aviation
Main concern for start of this TAF period will be areas of patchy
dense fog that have developed across portions of southeast michigan
this morning. Periods of mostly MVFR visibility with low ceilings
will be possible throughout the morning as patchy dense fog has
developed along i-69 and northward. Lowest visibilities are affecting
fnt so far where some visibility have dropped to lifr. Expect fog to
begin burning off by mid morning. Winds remain light through this
afternoon and shift out of the southeast with diurnal cumulus
development. Potential exists for showers and thunderstorms this
afternoon. Activity will be scattered in nature leading to low
confidence low and holding off any mention of storms in the tafs for
now.

For dtw... Ceiling and visibility has remained above ifr for much of
this morning, though there still remains some low potential to see
visibility dip to ifr. Anticipate ceilings to remain at or below
5,000 ft throughout today.

Dtw threshold probabilities
* low for ceiling visibility down to 200ft and or 1 2 mile.

* moderate to high for ceiling 5 kft or less this morning into the
afternoon.

discussion...

little variation in the overall pattern to finish the weekend, as
southeast michigan holds position within the southern fringe of
surface ridging anchored over southern canada and beneath lower
amplitude mid level NW flow. This will sustain a relatively static
low and mid level thermodynamic profile, one still defined by a
generally seasonable deep layer temperature regime and moist low
level conditions. Some pockets of fog and or low stratus will exist
post-daybreak, gradually mixing out within the ensuing growth to the
boundary layer. This process may yield some larger differential
heating boundaries, particularly within the higher terrain. It will
be within this corridor - stretching from lenawee washtenaw counties
northeast into sanilac county - where the greatest potential for
convective development will exist under modest boundary layer
destabilization. Westward advancing lake breeze activity will help
focus any activity, while the passage of a very weak shortwave may
also augment the process. Environment characterized by pw over 1.3"
and weak steering flow will bring the risk of localized very heavy
rainfall within deeper cells. Highs today generally in the lower
80s.

Plume of deeper moisture will briefly vacate the region tonight and
Monday as upper ridging takes control. Near surface moisture will
remain elevated through this time - dewpoints of low to mid 60s.

Given the light wind field, this will present another opportunity
for some fog development early Monday morning. Greater deep layer
stability will support dry conditions beneath the ridge on Monday.

Highs again low to mid 80s.

A moisture laden system will then lift across the region Monday
night into Tuesday. Steady strengthening of mid level energy now
tracking through the rockies will induce surface cyclogenesis across
the plains over the next 24 hours. This process will establish a
corridor of strong northward moisture transport within the warm
conveyor. Lead edge of this moisture axis remains projected to lift
into southeast michigan Monday night, anchored along the northeast
advancing warm frontal zone and supported by increasing mid level
cva along the eastern expanse of the inbound height falls. Strongest
low level convergence may focus just to the north and west given the
trajectory of the surface low, but a solid soaking rainfall appears
likely overnight into Tuesday morning given the underlying dynamics,
high moisture content and weakly unstable profile. Less favorable
nocturnal timing - particularly after 06z - will place a limit on
the possibility of seeing more organized convective development with
this initial surge.

Upper wave tracks across the lower peninsula on Tuesday, dragging an
attendant cold front through southeast michigan late in the day.

Augmented by favorable diurnal timing, this ascent should elicit a
secondary convective response. The degree of destabilization remains
uncertain owing to that possibility that cloud rain disrupt the
heating process at times. Should a window for greater heating
emerge, then an increasing deep layer wind field at the same time
may provide an opportunity for more organized thunderstorm activity
Tuesday afternoon.

Marine...

an area of high pressure with a weak wind gradient will slide east
through the great lakes today. This will bring light winds and low
waves, which will remain into Monday. A strengthening system across
the plains will move into the region Tuesday bringing unsettled
weather conditions. Winds will increase out of the northwest to
around 20-30 knots resulting in much higher waves by Tuesday night
and into Wednesday.
