Aviation
Minimal aviation concerns through tonight as high pressure slides
across the state. Cirrus deck just south of the state line will
slowly lift through SE mi providing the only cloud cover until early
Thursday morning. Models are indicating a plume of moisture coming
inland off lake erie which could spread a lower cloud deck northward
as winds become southeasterly. Lower CIGS will work north Thursday
afternoon as a low pressure system passes just south of the area.

For dtw... Introduced rain snow mix starting 18z Thursday as the
precipitation shield northwest of a passing low pressure system
lifts into the area. Confidence is low in ptype, as warm
temperatures may lead to all rain during the day, changing to snow
after sunset.

Dtw threshold probabilities
* low for ptype of rain snow mix Thursday afternoon.

* low for CIGS below 5000 ft through tonight. Medium Thursday
afternoon.

quiet weather expected today as a high pressure lifts through the
great lakes. Low level winds will begin veering from w-nw towards
the e-se as this high pressure moves off to the northeast throughout
the day. This will gradually bring an end to the lake effect regime
off of lake michigan with dry air already decreasing cloud cover
across southeast michigan early this morning. Even though there will
be more Sun today, the cold start to this morning with temperatures
around 20 degrees should only allow a thermal recovery into the
low mid 30s. Lows tonight will drop down in the 20s.

On Thursday, michigan will be placed in a zone between a closed low
lifting out of the lower mississippi valley and an approaching
northern stream shortwave across central canada. The low level
southerly flow ahead of the low approaching from the south will help
push some of the colder air out of the region as it moves into the
tn and oh valley. The leading edge of moisture wrapping around the
low with the deformation fgen band will push northward and reach the
michigan state line by around noon. Temperatures will be above
freezing in the mid upper 30s as precipitation moves into lower
michigan during the early afternoon. Soundings suggest a period of
rain or a rain snow mix with wet bulb cooling occurring.

Precipitation has a better opportunity to transition over to snow as
temperatures cool further after sunset. Potential also exists under
southeasterly flow that some locations could maintain warmer lower
level profiles, which would limit snow potential. Will keep periods
of rain snow mix for most of the day period and a better chance for
snow after sunset. Given the uncertainty still with this event,
snowfall of up to an inch or less looks reasonable at the moment.

The southern stream system will push east of the forecast area by
Friday morning as the northern stream shortwave crosses through
ontario. Bulk of the heaviest precipitation should stay north of our
cwa as height rises move in from the south. Wind direction on Friday
will bring the return of the lake effect regime with more clouds and
scattered light snow showers for areas along and north of i-69.

Below normal temperatures will continue through the weekend with
occasional chances for snow given the longwave trough pattern that
persists into the long term.

Marine...

there will be a decrease in the northwest winds and the waves today
as high pressure expands into the region from the west. This high
will drift east of the area tonight, supporting a backing of the
wind to the south-southwest by Thursday morning. After a brief
uptick in the wind speeds overnight into thurs morning, speeds will
again decrease thurs afternoon as weakening low pressure lifts into
the eastern great lakes. A cold front will push across the region on
Friday, resulting in a veering of the winds from south to west-
northwest and modest uptick in wind speeds.

Lake huron... None.

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.
