Discussion
Post-frontal cold advection has run its course leaving the forecast
area within a modest thermal trough characterized by 850mb
temperatures in the lower single digits for the remainder of the
day. Full insolation maximize boundary layer growth within this
environment while building surface high pressure beneath the
incoming shortwave ridge ensures light winds. Progged mixing depths
of 850mb or slightly higher are perfectly reasonable and suggest
highs in the mid 60s. Weak gradient will allow the sea breeze to
make an appearance in the afternoon in the typical areas. Modest
airmass modification and weak warm advection get underway on
Thursday as flow response to the approach of the well-advertised
northern stream wave. Low amplitude wave emerging out of the trough
anchored over the southwest us this morning will shear across the
ohio border in advance of this feature, just bringing a very slight
chance of transient light showers early Thursday morning. Poor
moisture quality and forcing preclude an inclusion of wx in the
forecast attm. Instead, expect temperatures at least a 2-4 degrees
warmer than Wednesday with variable coverage of high clouds as
deeper moisture remains confined well south until Thursday night.

Rather complex longwave amplification sequence will take place near
and downstream of the state Thursday night into Friday as lead
energy presently over washington begins to phase with the
increasingly sheared closed low over the SW us just as a trailing
110kt upper jet injects additional energy while ushering the entire
process east. The highest confidence takeaway at this time is that
the bulk of this process will occur downstream of the cwa, leaving
se michigan in a potentially strongly forced but poor moisture
environment. If nothing else, strong dynamic forcing along the
developing cold front will be worth chc pops early Friday. Pattern
then quickly returns to lower predictability fast-moving westerlies
suggesting occl precip chances and a tendency for temps to stagnate
on the cooler side of climatology.

Marine
A modest northwest wind this morning will turn light and variable
into the afternoon as high pressure moves across the region. Wind
will emerge from the south tonight as this high settles to the east.

Modest southwest winds will exist across lake huron Thursday as a
weak frontal boundary lifts into the great lakes. Meanwhile, winds
over lake erie will shift to easterly as a weak low pressure system
tracks through the ohio valley. A period of moderate northwest winds
will then develop in the wake of this system and frontal bondary on
Friday.

aviation...

a stray patch of stratocu could brush mbs and fnt during the early
morning but a ceiling is not expected as clouds continue decreasing
across the thumb region. Diminished wind and clear sky result in
favorable aviation weather across the rest of the terminals. Dry
weather under bands of high clouds with light wind comprise
conditions as high pressure slides across the region through
afternoon.

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.
