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.

Discussion A little bit of snow fell across northwest montana
including lookout pass earlier today. Expect a downtick in
precipitation this afternoon and evening. Watch out for black ice
across northwest montana this evening as temperatures cool. Some
clearing is expected this evening into the overnight, just enough
to allow for people to glimpse a few "shooting stars" from the
geminid meteor shower which is set to peak at 5:30 am mst Friday
The warm weather will continue on Friday as high temperatures will
rise into the 40s most places and potentially near 50 degrees in
central idaho and in the mission, bitterroot and deer lodge
valleys. Strong gusty winds near 50 mph are expected for the
camas prairie including grangeville during the day Friday. This
will bring dangerous crosswinds for high profile vehicles along
A cold front will move through the region Friday night, initially
bringing snow to mountain passes. Behind the cold front, lowering
snow levels and unstable conditions will lead to snow showers
that may organize into bands. Light valley snow accumulations will
be possible with the showers and bands which may lead to icy
roadways. Salmon is forecast to remain in an inversion, which
could lead to higher snow chances than we currently have in the
forecast Saturday morning.
High pressure briefly moves into north-central idaho and western
montana for Saturday night but the next, weakening, weather system|
is expected for Monday. The warm nature of this shortwave may
result in mixed precipitation.
The middle of next week will be active with many models bringing
another cold front into the northern rockies. There is
considerable disagreement between global deterministic models, and
ensemble models indicate a lot of uncertainty in the timing and
strength of features, but all guidance agrees well that the period
will be active.
Temperatures are expected to be near or above average for this
time of year, which is around 29 to 30 degrees in most urban areas
of montana and warmer in central idaho. This means the daily melt
and refreeze cycles will continue in the long term with daytime
precipitation often falling as snow, melting or partially melting,
and then refreezing. So areas of ice will continue to be an annoyance
for the region.
Aviation Light snow will taper off across northwest montana by
14 0000z with some mountain obscuration, but not expecting to
impact kgpi that much. Some clearing is expected this evening into
the overnight. Gusty winds to 40 kts are expected along the
continental divide, near anaconda to warm springs in montana and
also near the camas prairie, idaho tonight through Friday
afternoon. Watch out for downslope winds near 50 kts just north of
high camp 14 1800z to 15 0000z.

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.
