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 (today and tonight)
issued at 409 am cdt Tue oct 23 2018
another morning lies ahead with clear skies. There are some
patches of overcast near mille lacs lake and in barron, rusk, and
chippewa counties in wisconsin, but these should scatter out as
the morning progresses.
High pressure will build southward today and highs should be
about 10 degrees cooler than yesterday. Winds will be light
through tonight as the ridge passes nearby. Lowered temperatures
some tonight with the high center drifting just by to the east.
Models keep temperatures a bit milder due to not fully decoupling
the winds. Like Sunday morning, there should be many locations
dropping into the low to mid 20s across central mn and western wi
with calm winds lasting through the night.
Long term (Wednesday through Monday)
issued at 409 am cdt Tue oct 23 2018
the main theme for the long term period continues to be the
weather turning more cloudy with a few chances for rain as large
scale troughing with multiple rounds of individual shortwaves sets
up across the northern plains into next week.
By tomorrow morning the surface high will be moving into the great
lakes and winds locally will turn southerly. The first shortwave of
the period will lift northeast through nebraska and bring rain to
the area late Wednesday night through Thursday as PV and theta-e
advection into mn produce light across much of the area. This wave
is lacking jet support and instability, and low and mid level
forcing will be modest, so amounts should be relatively light.|
Longwave troughing over the area will then take hold through at
least this weekend, meaning reinforcing cool and cloudy weather.
Another shortwave will drop south from canada and bring a chance of
rain for Friday through Saturday, before drying out early next week.
The GFS continues to be more aggressive in developing a strong low
pressure system across the center of the country by midweek, but
ensemble guidance indicates plenty of spread in terms of timing and
strength, introducing plenty of uncertainty to any one particular

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.
