Aviation
Stagnant pattern in place over southeast michigan with surface high
pressure in place. Well organized equivalent potential temperature
advection in the lowest 4.0 kft agl will keep atmosphere primed for
low cloud. Uncertainty exists when cloud will be able to scatter
out. Went fairly aggressive in keeping cloud in place before
improvement this afternoon.

For dtw... Regional satellite support extensive stratus deck this
morning. No evidence in fog over far southeast michigan. Uncertainty
exists in dissipation of stratus today.

Dtw threshold probabilities...

* high in ceilings below 5000 ft this morning.

discussion...

sensible wx through the end of the week will be defined by the
evolution of the upstream longwave ridge the axis of which extends
from lake superior south into the lower ms river valley at press
time. Consensus among the nwp remains strong that this ridge will
edge eastward ever so slowly and will reach the lower great lakes by
Saturday before acquiring a positive tilt as it begins to deamplify.

Gradual modification of the thermal profile during this time will
lend itself to a warming trend today through Saturday, but the first
order contributors to temperature trends will more likely be cloud
cover and surface wind due to marine influence within southeast
flow. Temperatures today similar to yesterday as stratus and fog
have built back in within stable northeast flow. Increasingly
anticyclonic flow combined with diurnal heating should allow most of
the existing stratus to mix out or at least break up to a
considerable degree by this afternoon. However, forecast soundings
suggest a similar scenario tonight and have therefore retained the
inherited mention of fog. Boundary layer finally dries out by
Wednesday allowing mostly sunny skies to warm daytime highs toward
80 degrees. Airmass modification and veering surface wind supports
low to mid 80s areawide by the end of the week.

Marine...

high pressure will drift across the northern great lakes through mid
week resulting in light winds and waves. Winds will veer to the
southeast today. An approaching trough will then bring a slight
increase to southerly winds to around 20 knots.

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.
