Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Short term (today through Thursday)
issued at 348 am cst Wed nov 22 2017
the main focus is on the light snow forecast for later today, but
otherwise thanksgiving day will be free of any precipitation to
affect travel related to the holiday.
We will be recovering from yesterday's cold snap today. An area
of high pressure will move through the northland early today,
bringing milder air and a period of sunshine. Highs will be back
to the lower to middle 20s, and without the strong wind. A weak
area of low pressure will move into the dakotas today and spread
clouds and eventually light snow into the northland from the west.
There is high confidence in this snow, and high confidence the
snowfall amounts will be less than one inch. The snow will mainly
affect the northland during the middle of the afternoon through
the evening, and while the snowfall will be light, it could make
for icy conditions for travelers on the roads.
Another area of high pressure will move through later today and
early Thursday. Southerly flow will develop Thursday, bringing
warmer air into the region. Expect partly cloudy skies and highs
ranging from the middle 20s near the canadian border to the lower
30s from central minnesota into northwest wisconsin.
Long term (Thursday night through Tuesday)
issued at 348 am cst Wed nov 22 2017
a strengthening system passes just to the north of the canadian
border on Friday evening. As it approaches, it overruns cold air
causing a freezing rain threat in the minnesota arrowhead on
Thursday evening through the system is fairly starved for moisture
at this time, so expect only light ice accumulations. The
sharpest point of the upper level forcing trough passes overhead
Friday afternoon as we're solidly in the warm sector causing just
cold rain before transitioning over to snow Friday night with only
light accumulations expected as colder air funnels in.
High pressure builds through Monday before the next system begins
to move into the area. A potential frontogenetic band sets up
near the forecast area Monday evening which causes some concern
especially if the more aggressive GFS deepens a low over
wisconsin sending a deformation band over areas that may have
previously experienced some snowfall in the frontogenetic band.
Either way, there still is a lot of uncertainty in this timeframe
since there still is a lot of disagreement between models. It does
bear watching though as the 00z GFS solution would be quite

snow will spread in from northwest to southeast this afternoon
into the evening hours as a shortwave quickly moves through. This
will bring lowering ceilings to MVFR levels, generally between
1200-2500 feet. In addition, snow will reduce visibility to
MVFR ifr conditions. Confident on the ceilings as the latest
guidance is in good agreement with current observations. Less
confident on visibilities, but utilized upstream observations to
get an idea on how low visibilities will drop at times.
Snow will end at all terminals between 01-06z. AfterwardsVFR
conditions are expected as high pressure builds in.

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.
