Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Short term (this evening through Wednesday)

high pressure axis in place over the area though still cold enough
to generate a lot of low level clouds. Some of these clouds are
precipitating mainly off of the lakes.
Warm air advects in for Wednesday where temperatures will climb
above freezing in most locations. Clouds will likely still be
scattered to broken across the forecast area with better chances
for clearing in the south.
Long term (Wednesday night through Tuesday)
issued at 250 pm cst Tue nov 13 2018
moisture begins to advect into the region on Thursday as a broad
area of low pressure nears. An upper level vort MAX will provide
lift for some light precipitation across the area. The main
concern here is whether it will fall as snow or freezing rain.
Soundings indicate more snow towards inl while freezing rain is
more likely in NW wi. This forecast tended to go a little cooler
with more snow than fzra expected. While initially more of a
freezing rain sounding - the lower atmosphere is only shallowly
saturated with a dry layer above followed by a saturated cold
layer above that. This should lend more to the seeder feeder
mechanism inoculating the lower clouds with ice crystals. This
feature is most prominent at inl, but is less so at dlh. Despite
the precip type, the QPF amounts are minimal <0.10", so do not
expect this to cause too many issues.
The same system will turn winds to the NW which should cause lake
effect snow over NW wi again. This bout should be shorter in
nature than the last with a few inches of accumulation.
After this system passes, high pressure builds through Monday
though some fairly cold air skirts the region to the northeast.
Another clipper type system or two slides through on NW flow

even though high pressure will be nearby, a mix of MVFR andVFR
cigs were occurring across the terminals. These clouds should last
through mid day Wednesday.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
