Aviation
Light winds and mostly clear skies expected to hold during the night.

There is low chance for radiation fog developing across northern
taf sites toward sunrise and or MVFR stratus developing off lake
huron, but will maintain just a scattered wording for now. Otherwise,
increasing high clouds toward morning expected to help mitigate fog
potential at TAF sites, but fnt and ptk stand the best chance of
seeing a vsby restriction. A solid mid deck of clouds should be
around during the morning hours, with some CU up around 5000 feet by
afternoon, with isolated showers possible once again, mainly across
thumb region. Light northerly flow off lake huron post sunset may be
able help sustain sct-bkn 4-5 kft clouds during the evening.

Dtw threshold probabilities...

* low for ceiling 5000 feet this afternoon into the evening.

discussion...

quiet stretch of weather at least through the weekend as expansive
area of high pressure tracks across ontario and the northern great
lakes before stalling slightly over quebec and the NE CONUS for a
couple more days. Positioning of the high will send steady feed of
cool and dry air into the region. This will result in temperatures
remaining a few degrees below normal for the coming week. Normal
highs are around 80 and lows are around 60.

The mid levels are a bit more exciting with a compact vort max
diving through southern mi Thursday. This wave is the next trough to
rotate around the dominate upper level low lifting NE out of western
quebec. This wave will increase cloud cover over SE mi Thursday
morning with a small chance of seeing some isolated showers in the
afternoon. The early morning clouds may prevent any shallow fog from
developing. Moisture depth is thin with pwats only around a half
inch. Better chance of precip will occur across the eastern thumb as
northern flow behind the trough axis excites lake effect clouds and
possibly some showers as cool air advects over the warm lake.

After Thursday the high will take a firm grasp over the area with a
mid level shortwave ridge working into the great lakes. Upper level
flow becomes very weak across much of the country as strong
westerlies emerge across canada. This is where model solutions start
to diverge. A mid level wave will cut off over the midwest and try
to drift into the state but may take a few days with no steering
flow. One thing to watch will be remnants of the developing tropical
system harvey over the western gulf of mexico. Airmass will be quiet
dry early next week when the trough tries to drift across lower mi,
but if the system finds itself a bit further north and east after
making landfall, the trough may be able to tap into it for moisture.

Marine...

the pressure gradient is forecasted to weaken considerably tonight
in response to surface high pressure finally building into the
central great lakes. Northwest winds tonight are expected to ease
into the 15 to 20 knot range. A secondary cold front structure is
expected to push southward and release off of lake huron during the
day on Thursday. Winds are forecasted to veer to the northeast
during the afternoon and range between 10 and 15 knots. Cooler air
and lift along ahead of this boundary may create a favorable
environment for waterspouts, especially where any land breeze
development is possible. High pressure will eventually settle
overhead by Friday, bringing enough dry air to inhibit cloud
formation and produce favorable wind and wave conditions through the
weekend.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
