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.

High pressure will maintain generally clear skies and light winds
throughout the forecast period with a trend to south southwest
return flow around this high by midday Thursday. There will be some
chance of shallow, patchy fog late tonight, but confidence remains
low so will just carry forward previous forecast of MVFR br attm.

Dtw threshold probabilities
* none.

discussion...

southeast michigan now firmly entrenched within a dry but moderating
environment, governed by a fleeting mid level northwest flow along
the downstream flank of encroaching upper ridging. The corresponding
high degree of stability reinforced by existing surface high
pressure yielding pleasant conditions today under nearly full
insolation. Little variation in the overall pattern heading into
tonight, as the center of the surface anticyclone settles directly
across the local area. This setup will yield favorable radiational
cooling conditions overnight, given maintenance of a clear sky, good
depth and magnitude to the dry layer and light wind field. Broader
distribution in low temperatures likely within this profile - mid
40s in the coldest locales to mid 50s within portions of metro
detroit. While near surface conditions continue to dry under the
full Sun today, this environment will again be supportive of some
fog formation during the early morning hours.

High amplitude upper level ridging will define conditions throughout
the latter half of the week. Deep layer warming as upper heights
build regionally will translate into well above normal daytime
temperatures through this period. A standard mixing profile under
full insolation will support highs of lower 80s on Thursday, as 850
mb temperatures climb into the mid teens. An additional low level
warm air advection component as flow turns southwesterly will nudge
daytime temperatures into the mid 80s Friday. Low temperatures will
continue to carry more variability, with the typically colder
locations still susceptible to greater radiational cooling. A
gradual increase in humidity noted through the period, particularly
on Friday as dewpoints nose toward 60 degrees late in the day. No
precipitation expected through the daylight period Friday.

Chance for showers and thunderstorms increases on Saturday as height
falls approach from the west while ample warmth and moisture is
present at the surface - highs in the mid-upper 80s and dew points
in the 60s by the afternoon. Scattered coverage of storms will be
most likely for our area on Saturday, but better forcing will likely
be located over northern michigan as a series of shortwaves in the
upper pattern quickly move through. Potential for unsettled weather
remains through the weekend as upper troughing lingers overhead, but
not expecting more than a few isolated showers and storms for
Sunday. Highs will remain in the 80s.

Height rises will return by Monday and a surface ridge will move
back over the region. This pattern will dominate the early week
period, leading to quiet and pleasant weather with highs in the 80s
and lows in the 60s.

Marine...

high pressure centered over southern lake michigan will produce
favorable conditions across the lakes through Thursday. Winds will
become light and variable overnight as this high expands across
lakes huron and erie. The high will drift to the east coast by
Friday as a slow moving front approaches from the northwest. Light
south-southwest winds will develop by Friday and will persist into
the weekend. Friday will remain dry but chances of showers and
thunderstorms will return Friday night through the weekend.

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.
