Aviation
High pressure across the upper ohio valley will sustain dry
conditions with clear skies and light winds through daybreak. The
departure of the sfc high to the mid atlantic Wednesday morning will
establish an increasing south-southwest gradient across SE mi.

Deepening of the mixed layer during the course of the day will then
result in a modest uptick in the winds. Otherwise, dry air in the low
level will maintain clear skies below 10k ft through Wed afternoon.

Dtw threshold probabilities...

none.

discussion...

shortwave dropping through back side of mid level trough is clipping
eastern michigan this afternoon and evening. Very cold airmass
aloft as this mornings sounding indicate freezing level around 6kft
combined with strong diurnal heating is yielding capes upwards to
around 1k joules producing scattered showers mainly from the thumb
and saginaw valley on north. Expect this activity to continue into
the evening before dissipating around sunset. Some light shower
activity could make it down to the detroit area briefly during prime
heating. Some thunder is possible as -20c is just a mere 16kft above
the surface. After... Skies will clear early tonight as surface high
pressure slides by to the south and mid level heights rise. Wednesday
will start off mostly sunny but clouds will begin increasing from
the west during the afternoon as WAA around backside of departing
high begins. Shortwave tracking through the upper midwest will spin
up a weak surface low Wednesday that will track east across the
northern great lakes. Showers and thunderstorms will develop over
wisconsin and spread east-southeast along a strengthening warm front
that will be lifting north through lower michigan tomorrow afternoon.

Expect the best chance for showers and thunderstorms to occur late
afternoon evening across the saginaw valley and thumb. This area will
be sensitive to any heavy rainfall after major flooding over the
weekend. Activity shouldn't last too long and expecting maybe upwards
half an inch. There should be a break in activity after warm front
passage but showers and thunderstorms will return later Wednesday
night as a cold front moves through lower michigan down to along the
southern border Thursday morning where it will stall as main
shortwave lifts northeast into ontario.

Thursday should be rather quiet for most of the forecast area as mid
level ridge slides through but showers and thunderstorms will still
be possible especially across the southern two tiers of counties in
the vicinity of the stationary front. Another stronger shortwave in a
broader deepening trough will advance towards the great lakes
Thursday night. In response the stationary front will lift back north
as a warm front bringing a chance for showers and thunderstorms
across the area. Temperatures will be more seasonable the next couple
of days.

Extended forecast Friday june 30th through Wednesday, july 5th:
models showing little change in the forecast from yesterday with wet
weather pattern still expected to resume mid-week and continue into
weekend as several waves of low pressure move through SE mi. Chances
of showers thunderstorms still look to increase by Friday afternoon
and evening with a few showers lingering about for Saturday. Surface
high pressure is delayed until Sunday on new run, along with the
upper level trough. Upper level troughs could still be a bit of a
fly in the ointment triggering scattered showers Sunday through
Tuesday. At present, the vort maxes disappear for Wednesday as high
pressure gets a slightly better footing over the area; translation,
drier conditions and less clouds Wednesday. Temperatures continue to
hold near the seasonal norm through the period with highs in the
upper 70s to low 80s and overnight lows in the 60s.

Marine...

moderate westerly winds will hold throughout the afternoon as
diurnal heating over land brings the slight chance to see isolated
showers over the saginaw bay, and along the western coasts of the
great lakes. Overnight, winds will shift from westerly to more
southwesterly as nocturnal stability acts to keep winds light. High
pressure moving east across the ohio valley will act to keep
conditions dry throughout Wednesday and will usher in warmer air
into the region, bringing more stable conditions over the lakes as
gusts remain sub-15 knots. Thunderstorm chances then move in
Wednesday night into Friday as a series of low pressure systems help
to advect warm, moist air into the region.

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.
