Marine Weather and Tides
Harbor Beach, MI

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Aviation
Satellite would suggest variability in the depth of the fog layer
across SE mi early this morning. From ptk up through fnt, the fog
may persist past 13z given the depth indicated on satellite. As for
metro detroit and mbs, the shallow nature of the fog and recent vsby
trends suggest visibility improvement by 12z or shortly thereafter.

Otherwise, high pressure overhead will sustain clear skies and light
winds through the TAF period.

Dtw threshold probabilities
* none.

discussion...

morning fog, especially north of i-69 where dense fog has developed
(issued dense fog advisory down to the m-59 corridor), will burn off
by mid morning as the late may Sun GOES to work. Dry and warm
stretch of weather will commence today as upper level ridge axis
advances into the central great lakes region, arriving on Friday.

Large diurnal temperature swings in store, and with large surface
high (1022+ mb) lingering tonight, fog remains a possibility, as 00z
nam condensation pressure deficits crash overnight, although NAM may
be a bit too aggressive and will just include patchy fog for now.

850 mb temps of 12 to 13 c today will support highs near 80 degrees.

Low to mid 80s on Thursday as low level southwest winds begin to
take hold and 850 mb temps reach and slightly exceed 14 c. Good warm
return flow around the high on Friday will support highs in the mid
to upper 80s as 850 mb temps reach and slightly exceed 17 c. Airmass
looks to remain relatively stable right through Friday. The airmass
will then destabilize over the weekend as height falls take place and
general troughing becomes established over the great lakes region,
although bulk of upper level energy disturbances to track through the
northern great lakes. None-the-less, sufficient instability moisture
likely over southeast michigan to lead to some shower and
thunderstorm activity, but coverage and timing remains problematic
this far out. Cold front still draped across far southern lower
michigan on Monday will maintain the low chance, but large surface
high looks to build back in Monday evening into Tuesday, per 00z
euro, providing another couple days of dry and warm weather.

Marine...

light west-northwest winds will occur across the lakes this morning
ahead of high pressure now centered over southern lake michigan.

Winds will become light and variable during the course of the
afternoon as this high expands across lakes huron and erie. The high
will sustain light and variable winds into Thursday. As the high
drifts to the east coast by Friday and a slow moving front
approaches from the northwest, light south-southwest winds will
develop by Friday and will persist into the weekend.

Dtx watches warnings advisories
Mi... Dense fog advisory until 9 am edt this morning for miz047>049-
053>055-060>063-068>070.

Lake huron... None.

Lake st clair... None.

Michigan waters of lake erie... 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.
