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.

Discussion A moist and unstable atmosphere will continue to
support scattered snow showers over north central idaho and
western montana this evening and tonight. A few of these showers
may organize temporarily into bands and produce isolated areas up
to one inch in the valleys (mainly between kalispell and darby)
in the evening. In addition, lolo and lost trail passes should see
another 2 to 3 inches this evening. As such, roads will vary from
clear and dry most areas to pockets with snow cover and
slick... So be watchful.
Weak high pressure and dry condition should return Tuesday
Snow showers will begin to move west across the idaho panhandle
into lincoln county, mt by Tuesday evening. This area of showers
will extend southward through much of idaho and clearwater
counties of idaho through the night, making a slow progression
eastward across the rest of western montana during the day
Wednesday. Mountain snow will continue through at least Wednesday
night, causing a prolonged period of light to moderate snow to
steadily accumulate in terrain above 4000 feet. As a result, those
traveling over lookout, lolo, or marias pass should expect
changeable conditions and periodically low visibility.
Snow that falls in valleys Tuesday night through Wednesday morning
will transition to rain, or a sloppy rain snow mix, by Wednesday
afternoon across all of central id and western mt. Snow levels
will rise to about 5000 feet Wednesday, then lower back down to
valley floors by Thursday morning. Rain will then change back to|
snow by Thursday morning, with lingering widespread snow showers
persisting thereafter. Additional snow accumulations of a few
inches are possible through Friday. All in all, Tuesday through
Friday will be quite the "weather rollercoaster".
The main storm track may shift a bit northward (still some
uncertainty on how much) Saturday and Sunday. As this occurs,
slightly warmer air will slowly work northward. However,
considerable moisture should channel across north central idaho
and mainly northwest montana. Snow levels should start out near
valley floors and raise slowly over the weekend to near pass
In the longer term, models are fairly consistent showing another
cold and moist trough of low pressure affecting the northern
rockies, with another round of wintry precipitation next week.
The bottom line is: a quite moist weather pattern is expected for
the next 7 to 10 days with mountains picking up significant
amounts of additional snow and valleys going back and forth from
rain and snow.
Aviation A moist and unstable atmosphere will linger over the
northern rockies this evening and tonight with scattered snow
showers. Under the snow showers, low ceiling and visibilities with
terrain obscurations can be expected. Kmso, kgpi and kbtm will be
the airports most impacted by possible snow showers into tonight.

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.
