Ridge of high pressure will maintain clear skies overnight with only
few-sct diurnal cumulus on Monday. There may be a period of MVFR fog
overnight, mainly kdtw kyip. Otherwise,VFR. Winds will remain under
10 knots (and under 5 knots much of the forecast period).

Dtw threshold probabilities...

* none.

discussion...

record highs continue to fall here in southeastern michigan with the
upper level omega block ridge in place over virtally all of eastern
north america. The centroid to the upper level ridge axis has now
drifted to the east, but wavelength is large enough that a main
chunk continues to grip the area. Local maximum in thermal ridge
supported temperatures running over 90 degrees in many locations.

Record highs have been broken outright today at both mbs and fnt,
with the most recent temperature back to within one degree at dtw.

The exception has been the immediate shoreline areas adjacent to the
local waterways where a southeasterly wind trajectory has resulted
in some relief.

The thermal ridge axis will drift away from the state Monday
allowing southwesterly return flow to finally set up over the area.

The arrival of return flow is usually a harbinger of warmer weather
with warm air advection, but for this particular scenario the area
will actually see some cooling. The cooling may potentially be as
much as 2 to 3 degrees c at 850mb. Will continue to favor a warmer
solution with some increase in mixing heights. The forecast will
continue to call for upper 80s to around 90 degrees for maximum
temperatures at all locations both Monday and Tuesday.

Cold frontal passage remains progged to occur through the first half
of Wednesday with highs ranging from the mid 70s across the tri
cities to the low 80s across metro detroit where the frontal passage
will occur later. With better forcing staying well to the north of
se michigan and limited moisture ahead of the front, only a slight
chance of showers and thunderstorms will accompany the frontal
passage. Surface high pressure then builds into the region on
Thursday yielding pleasant weather as cooler 850 mb temps near 5 c
will limit highs to the mid 60s. A shortwave dropping southeast
through the great lakes on Friday will bring increased clouds and a
chance for showers along with a reinforcing shot of cooler air
keeping highs in the low to mid 60s to end the week.

Marine...

strong upper ridging will continue to influence the weather pattern
across the great lakes through Tuesday with dry weather and light
south or southeast winds, generally around 10 knots or less. A cold
front crossing the central great lakes Tuesday night will bring a
low chance of shower and thunderstorm activity. Winds behind this
front become northwest on Wednesday and increase to around 10 knots
for lakes st. Clair and erie, but in the 15 to 20 knot range for
lake huron.

Dtx watches warnings advisories
Mi... None.

Lake huron... None.

Lake st clair... None.

Michigan waters of lake erie... None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
