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.

Transition from rain to snow and colder expected on Friday...
Discussion Light mountain snow showers are spreading from west
to east across northwest montana and parts of west central
montana this afternoon. This area of precipitation is expected to
gradually increase in coverage through the evening and shift
southward with time. Mountainous terrain will receive light
accumulations of snow (roughly around 5000 feet and higher). The
mission and swan mountains could receive closer to a foot of snow
by Thursday morning. Valleys will largely miss out on any
appreciable moisture during this time.
That being said, conditions across northwest montana valleys late
tonight through Thursday morning will become more favorable for
freezing drizzle to occur. The highway 2 corridor, as well as the
highway 93 corridor through the flathead and northern mission
valley will be most affected by the potential for freezing
drizzle. If you have to travel Thursday morning, please use
caution, as roadways may become very slick very quickly!
Thursday afternoon through overnight, mostly cloudy conditions
will prevail with a passing shower, snow in high elevations, and
rain in the valleys.
Friday morning, an arctic cold front will begin to affect
northwest montana. Precipitation should start as snow, or a
rain snow mix, across most the area. In northwest montana, any
areas that begin as a mix should eventually change to all snow,
while the i-90 area will briefly change over to rain. The frontal|
passage is forecast to be from 4am to 5am in the kalispell area
then around 10am to 11am in the missoula area. After the passage,
gusty east to northeast winds will usher in colder temperatures. In
the valleys, winds will potentially gust above 25 mph. During the
afternoon, the valley rain snow line will progress further south,
reaching missoula sometime after 2pm to 3pm. Drier air is expected
to occur behind the front, which may cut off precipitation. If
this does not happen, the potential for snow will exist through
High pressure is still forecast to briefly return for early next
week, so valley inversions and fog will again be possible Monday
and Tuesday. Another snow-producing weather system is possible
Wednesday and during thanksgiving.
Aviation Stratus continues to plague valleys of northwest
montana, including kgpi, but has recently been showing
improvement this afternoon (as of 13 2100z). Otherwise, cloud
cover across the rest of the northern rockies will increase and
lower through the day as moisture in westerly flow increases.
Periodic mountain obscurations will be common this afternoon into
Thursday, along with light snow on the terrain. Confidence is low
to moderate for the potential for light freezing drizzle to impact
kgpi on Thursday morning... Likely between 14 0600z and 14 1700z.

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.
