Aviation
Surface high pressure centered over the eastern great lakes will
remain in control of aviation weather today and tonight. A light
southeast wind around the west flank of the high and into se
michigan will maintain enough humidity for scattered cumulus to form
during the afternoon under patches of higher clouds. This will
constituteVFR that will last through tonight until light fog
redevelops toward sunrise Tuesday.

Dtw threshold probabilities...

* none.

discussion...

record setting upper level ridge (00z dtx sounding revealed a 500 mb
height of 591 dam) is finally beginning to slowly weaken break down,
as upper level trough energy over the rockies heads off to the
northeast. 500 mb heights progged to fall to 585 dam on Tuesday, with
what looks to be a dry cold front tracking through Tuesday
evening night, as there is barely any instability, and mid level
lapse rates are pathetic as upper level support tracks off into
ontario.

High clouds and increase in moisture coming up from the south today
should help level off the high temperatures around 90 degrees, as
925 mb temps reach 25 c or slightly better. There is even
suggestions by hires models that moisture advection and instability
building up during the day will be sufficient to generate a few
showers and thunderstorms across the north half of the cwa, which is
not totally out of the question with the noted weak surface
trough convergence. Ultimately, the skinny CAPE with the dry mid
levels will probably be too much to overcome.

Another reasonable shot at 90 degrees on Tuesday, as light level
southwest flow developing ahead of the cold front should allow for
more uniform highs, with 925 temps still advertised to reach 25 c
and potentially slightly exceed.

Healthy low level cold advection on Wednesday, as 925 mb temps fall
into the mid teens by day's end, which should hold maxes mostly down
in the 70s. Continued cold advection Wednesday night, with 850 mb
temps also lowering into the 2-5 c range as surface ridge arrives
Thursday morning. Late september insolation should be able to boost
temps into the upper 60s to near 70 degrees, or near normal values.

Temperatures then look to drop below normal as we head into the
weekend with upper level trough sliding through during the Friday-
Saturday time period, with 850 mb temps falling to around zero per
00z euro.

Marine...

record early fall warmth will continue today through Tuesday. The
warm air and light southerly wind will produce ideal marine
conditions during this time. A cold front crossing the central great
lakes Tuesday night and Wednesday will then bring temperatures back
down toward normal along with a low chance of showers and
thunderstorms. Winds behind the front will become northwest at light
to moderate speed, although a few gusts near 30 knots will be
possible over the open waters of central lake huron. The part of the
forecast to monitor will be the associated higher wave pattern
remaining far enough offshore to avoid the need for small craft
advisories over southern lake huron. Another low pressure system and
cold front due Friday will bring a reinforcement of colder air and
unstable marine conditions for the weekend.

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.
