.what has changed...
a dense fog advisory has been issued for areas between the i-71
and i-77 corridors through 9am this morning. patchy fog is
likely elsewhere across the are as well.

&&

.key messages...
1) dense fog is expected this morning across central and
northern ohio with patchy fog likely elsewhere across the area.

2) high pressure builds into the region and dry weather and
warming temperatures are expected through the majority of the
week with a low chance of showers on wednesday.

key message 1...
dense fog as begun to develop across central and northern ohio
early this morning and will persist through around 9am.
visibilities are seen dropping down to a quarter mile or less in
places with dense fog creating hazardous driving conditions.
elsewhere throughout the area, fog has been less widespread
though there are areas of patchy, dense fog. may need an
expansion of the dense fog advisory in the coming hours if those
locations begin to become more widespread. fog should dissipate
this morning as temperatures begin to rise.

key message 2...
an upper level ridge begins to build into region starting on
monday and will persist through the middle of the week. dry
weather is expected and temperatures will rise into the upper
70s to low 80s by wednesday afternoon. on wednesday, a weak
trough is expected to move through the region that may provide
enough support for showers and thunderstorms throughout the day.
currently pops are fairly low, with the highest chance south of
the us 30 corridor with a isolated thunderstorm to the north
possible as well.

behind the trough, a surface cold front will drift south-
southwestward across the region and temperatures will drop down
near seasonally average, with highs in the mid to low 70s, for
the second half of the week. high pressure will build into the
region from the north on thursday bringing dry weather to end
the week. global models show an upper level trough developing
over eastern canada and moving south this weekend. currently
precipitation chances are low, but a cooler air mass moving into
the region is possible. though, there is plenty of spread among
models in regards to high temperatures, so confidence is low on
how cool it will be.

.aviation /12z monday through friday/...
the main aviation weather concern will be regarding low ceilings
and areas of dense fog with low visibilities early this
morning. conditions are starting off impactful for aviation with
lifr/ifr ceilings and visibilities this morning. flight
categories will improve quickly later morning. mainly vfr
conditions are expected by the afternoon through the late
evening. there is the potential for areas of low stratus
ceilings and fog with ifr conditions to redevelop after 06z
tonight. winds will be rather light and variable at times. a
general northeasterly flow of 5 to 8 knots will develop later
today into this evening.

outlook...non-vfr possible with rain showers in central ohio on
wednesday.

&&

.marine...
overall beautiful and quiet marine conditions are expected to
continue for memorial day and linger much of this week. high
pressure will build in across the region. winds will be light
and variable under 10 knots and waves of 1 foot or less are
expected to persist through mid- week.

in the short term, development of fog over the northern half of
our cwa this morning. currently have a dense fog advisory issued
for counties generally north of us-30 as the expectation for
dense fog had increased with decent radiational cooling
conditions with clearing skies, light winds, and moist low
levels (surface dew points in the 50s). latest automated
visibility reports have been showing visibility values dropping
steadily over the last few hours mainly over the northern half
of our cwa. reports of less than 1/4 mile visibilities and many
locations at or near 1/2 to 3/4 mile. will continue to monitor
through this morning for any extension of the advisory area but
at this time has held fairly well.

a decent day weather-wise will shape up for the memorial day
holiday with warming temperatures into the upper 70s to low 80s,
dry weather, and mostly sunny skies. perhaps a bit sticky with
dew points still in the 50s. tuesday looks to be fairly similar
with slightly warmer temperatures and increasing clouds through
the day. by wednesday morning a very subtle shift in a more
moist airmass will shift slightly northward with ridging
building over the southeast and northward through the central
conus will into central canada. this will slightly increase the
humidity levels across the area (dew points in the low to mid
60s). this will bring slight chances of rain showers and perhaps
a rumble or two of thunder mainly south of us-30 but most
likely for areas south of us-24. at the same time a shortwave
trough moving southeast over the great lakes region into ohio
river valley will bring slight chances of showers/thunderstorms
for our far northeastern parts of the cwa.

otherwise, the remainder of the week into the weekend looks dry
and will remain warm (highs in the upper 70s to low 80s) with
the previously mentioned ridging strengthening and develops a
synoptic omega type blocking set-up across the central conus.

- summer-like temperatures memorial day through wednesday, with low
chances for precipitation.

- more seasonably average temperatures return late week into the
weekend as well as a continuation of drier weather.

.aviation...

extensive ifr stratus with periodic patchy dense fog will hold
through this morning and will rapidly scour out 1-2 hours after
sunrise given the late may sun angle. this will then lead to mostly
clear skies for the remainder of the day. influence of high pressure
will keep winds light and will support more variable wind direction.
overnight, clear conditions hold for most locations. there is a weak
signal for some fog or low stratus development closer to kdtw as
lake erie moisture pools inland, but the overall signal for this is
too low to include in the taf at this time.

d21/dtw convection...no thunderstorms anticipated.

.dtw threshold probabilities...

* high for ceilings at or below 5000 feet this morning.

* low for visibilities of 1/2sm or ceilings at less than 300 ft this
morning.

while expansion of high pressure overnight initially supported areas
of fog development, this has subsequently lifted into a low stratus
deck across nearly all of se mi early this morning. this low cloud
and patchier fog gradually scatters through the remainder of the
morning as diurnal mixing beings to ramp up eventually resulting in
a mostly sunny second half of the day. center of surface high
pressure shifts east out over lake erie by afternoon establishing
light southwesterly flow locally. core of warm advection is focused
over central michigan supporting highs across the saginaw valley in
the lower 80s with the rest of se mi favored to see temps in the
upper 70s to around 80. ongoing warm advection aloft also looks
sufficient to keep the region capped today confining any isolated
pop-up thunderstorms (tied to a weak passing shortwave over the
northern great lakes) over northern lower mi instead. region remains
under the same high tuesday as it stalls over the eastern great
lakes. similar to today, main mid-level warm advection is focused
over central mi likely leading the saginaw valley to see the hottest
temperatures for our area with highs in the mid to upper 80s. rest of
the region can expect to see temps top out in the low to mid 80s.

a backdoor cold front is then set to sag south out of the upper
great lakes and through southern lower mi over the course of the day
wednesday. a compact shortwave riding along this frontal boundary is
progged to track over southern lake michigan/sw lower mi wednesday
evening offering chances for scattered showers and an isolated
thunderstorm late day mainly west of i-75 and south of i-69. broad
high pressure dropping out of northern ontario is quick to follow
with its influence holding for the rest of the week.

marine...

high pressure built into the area overnight and remains in place
today. flow has become southwesterly across the central great lakes
as a result. southwest winds may increase across the saginaw bay
area today, with speeds increasing to around 20 knots. by wednesday,
high pressure becomes quite elongated, stretching across the ohio
valley and into the northeast. a cold front then drops south across
the area late wednesday, with the next chance for showers and
thunderstorms. the mid-week cold front is not expected to be
particularly strong, so currently not anticipating any significant
ramp up of winds behind the front. another area of high pressure
builds into the region behind the front and will lead to varying
winds throughout the end of the week. there may be periods with
enhanced onshore northeast winds, which may elevate wave activity in
nearshore zones at times.
