Aviation
Lingering mid level cyclonic flow in conjuction with daytime heating
will again support an extensive high basedVFR CU this afternoon.

This may also yield isolated shower development, but with coverage
and duration too limited to mention. Moderate west-northwest winds,
with the occasional gust to 20 knots through peak heating. Benign
conditions tonight as high pressure settles in and nocturnal
stability takes hold. This will leave skies clear with winds
becoming light west to southwesterly.

For dtw... Brief window this morning of CIGS below 5000 ft, with
predominant conditions above this threshold by afternoon.

Dtw threshold probabilities...

* low for cigs AOB 5000 ft this morning.

discussion...

low pressure tracking into georgian bay will continue to drag an
axis of moisture across southeast michigan early this morning. This
will generate a few light showers, primarily north of m-59. The
showers should exit the thumb by about 8am, allowing the atmosphere
to recover a little through the mid-morning hours before shower, and
possibly thunderstorm, chances are renewed.

Upper shortwave diving through ontario and away from st james bay
will clip across northern and central michigan today. This should
help generate showers and a few thunderstorms again during the
afternoon and evening. Weak theta-e advection and only modest
instability should limit coverage to lower-end scattered. Low
freezing level (6-7kft) will once again bring the risk for small
hail with any thunderstorm that develops. The wave will exit east
during the late evening, leaving subsidence and drier air in its
wake. The remainder of the night and most of Wednesday look dry as
high pressure centered over the ohio valley extends northward into
lower michigan. Temperatures will undergo a moderating trend over
the next few days, with MAX temps reaching back into the upper 70s
by Wednesday as southerly flow increases.

Active pattern then setting up from Wednesday night through the end
of the week as upper energy now pushing through oregon tracks
through the upper midwest and great lakes, and is followed by the
upper low now over british columbia and alberta. Strong low-level
jet will usher warmer air and moisture into the area Wednesday
night, spiking pw values up close to 1.75 inches. Idea is still for
storms to develop over the upper midwest Wednesday, and lift across
michigan Wednesday night, with better chances for showers tstorms
over central and northern lower michigan. Steep mid-level lapse
rates and 0-6km bulk shear around 30 knots could favor hail with
stronger storms, but elevated nature of storms would limit damaging
wind gust threat. Occluded surface low will track near the u.P. On
Thursday, dropping a weak front through southern michigan. This
boundary will then serve as a focus for additional showers tstorms
Thursday. While best chance for strong to severe storms looks to be
just south of the area, cannot rule out a few severe storms over
southern michigan. Main concern with convection during the middle to
end of the week will be potential for storms to produce very heavy
rainfall in a short period of time. Areas where flood waters are
still receding will be most vulnerable.

Marine...

a period of moderate west-northwest winds will exist today as mid
level troughing slowly relinquishes control. Winds will ease
tonight under weak high pressure. Moderate southerly winds then
emerge on Wednesday in the wake of this high. South to southeast
winds will persist through Thursday, as low pressure tracks through
the northern great lakes. Increasing stability as warmer air
returns under this pattern will limit the gustiness. There will be
a chance of thunderstorms Wednesday night through Friday.

Hydrology...

the next chance for organized rainfall will exist Wednesday night
into Thursday. The latest forecast indicates up to one half inch of
rain will be possible through this time. However, localized higher
amounts in excess of one inch could occur within any heavier
thunderstorms. This would result in rises on area rivers and
streams, while potentially creating some minor flooding. The
extremely saturated conditions still existing across the tri-cities
and northern thumb will make these locations even more susceptible
to a period of heavy rainfall. In the meantime, area river flooding
continues to gradually ease. The titabawassee has now fallen below
flood stage, with the saginaw river forecast to fall below flood
stage Wednesday morning.

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.
