Aviation
Early evening satellite trends support shower potential lingering in
the fnt to mbs area for a short while longer as daytime heating
wears out. Diurnal clouds then continue to fade during late evening
followed by thickening high clouds overnight. There remains a time
window for some light fog toward sunrise, especially in the fnt to
mbs area where heavy downpours occurred to add an element of wet
ground to boundary layer moisture. The prospects of increasing high
clouds and a nonzero gradient wind are expected to hold visibility
reduction to MVFR for a couple hours around sunrise. Clouds then
continue to thicken and lower during Monday while the chance of rain
holds off until later Monday evening.

Dtw threshold probabilities
* moderate for ceiling 5000 ft or less late Monday afternoon.

discussion...

similar pattern to yesterdays across the area with moist stagnant
low level. Weak surface pressure pattern has allowed several weak
differential heating and lake boundaries to develop. Capes values
pushing around 1k joules from daytime heating with weak capping have
lead to isolated showers so far that have briefly popped up then
quickly dissipated along the different boundaries. Low level
shortwave that was modeled to move more east across the area has been
drifting more southeast and will clip the southwestern portion of
the cwa. This may help a few showers thunderstorms develop more
across western side of the cwa. Though pwats are lower then
yesterday, heavy downpours are still possible with any more intense
cell that develops but should not see inch plus amounts like
yesterday. Any convection or convection chances will quickly
dissipate around sunset.

For tonight into Monday, upper level short wave ridging will slide
through the great lakes. Subsidence will lead to clear skies
tonight and first part of Monday. Low level will remain moist as
dewpoints remain in the low to mid 60s. Expect patchy fog
development again tonight with some locally dense fog in spots. For
Monday, plenty of sunshine the first part of the day will help highs
into the low 80s before mid and high level clouds begin advecting in
from the southwest ahead of the next system. This system is a
closed upper low currently centered over nebraska. This system will
lift towards lower michigan as it gets drawn up by large upper
trough over canada. Models develop a surface low with this system
and track it northeast through SW lower to northern lake huron by
Tuesday evening. Showers and thunderstorms along and ahead of
associated warm front will begin effecting the area near the ohio
border late Monday evening and spread through the area Monday night
and continue through Tuesday. Coverage of activity will become more
scattered behind the warm front and should end early Tuesday night
with passage of cold front.

Quiet and dry weather returns to the forecast Wednesday as heights
aloft rebound and high pressure builds in at the surface. Breezy
northwest winds Wednesday will taper off by the evening, becoming
light and gradually backing to southerly by Friday as the center of
the anticyclone moves eastward through the ohio valley. Cool air,
850mb temps around 8 to 9c, will linger over the area Wednesday in
the wake of Tuesday's cold front. High temps on Wednesday in the low
to mid 70s will moderate back into the low 80s by the weekend. The
next chance for precipitation comes late Friday into Saturday as a
shortwave lifts through the region.

Marine...

light winds and low waves will persist into Monday. A strengthening
system will affect the region Tuesday bringing unsettled weather
conditions. As the system passes, moderate northwest winds will
setup with gust approaching gales - mainly on lake huron - expected
Tuesday night into Wednesday.

Hydrology...

a seasonably strong storm system will sweep across the region Monday
night and Tuesday. Widespread rainfall is expected with totals
approaching an inch in many locations - with locally higher amounts
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.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
