Discussion
Conditions across southeast michigan will continue to be quiet
through the weekend. Only minor weather issue is the chance for
showers this afternoon. A quick moving shortwave moving through the
longwave troughing is what will bring a chance for showers to the
area, especially locations in eastern portions of the thumb. This
wave will also bring in more cooler air resulting in high temps only
in the 60s to around 70 degrees today. While temps do moderate
somewhat through the remainder of the week into the weekend, they
will remain a little below normal for this time of year.

High pressure coming down from canada then builds in behind the
departing trough as heights begin to build across the region. Dry
conditions will hold through the weekend before the potential for
another wave comes in early next week. Lots of uncertainty going
into the extended forecast for the beginning of next week, along
with the potential tropical systems. This means the area may or may
see some tropical moisture depending on how they interact with the
overall setup across the region.

Marine
An upper level wave moving through the southern great lakes will
support a surface front that will reinforce cool air over the region
today. Lift along and ahead of this boundary and the cooler air left
behind will create a favorable environment for waterspouts through
this evening. Land breeze development is then expected to occur over
the open waters of lake huron tonight but model soundings indicate
cloud depth will be too shallow for waterspout potential. High
pressure will then settle overhead Friday and further inhibit cloud
development. Wind and wave conditions will remain favorable through
the weekend as the high pressure system drifts slowly across the
great lakes.

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.

Dtx watches warnings advisories
Mi... None.

Lake huron... None.

Lake st clair... None.

Michigan waters of lake erie... None.

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.
