Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.

Discussion As the region transitions out of high pressure,
recent satellite feed has shown a progressive erosion of
northwest montana's stratus deck. In fact, most locations have
seen a mix of Sun and clouds throughout the day today, with
moderating temperatures expected.
An incoming weak weather system is then expected Monday through
Tuesday morning, which will bring light snow to the northern
rockies. Of particular interest is the potential for snow to
accumulate from orofino, idaho and south through the camas prairie
region. Confidence is low at this time, but there is still a
slight chance for a couple of inches of snow to impact travel in
A more widespread, snowier weather system will begin to affect
the area late Tuesday through Wednesday. Moderate to heavy snow is
likely for terrain 4000 feet and higher, which may also include
valleys hugging the montana idaho border where moisture will be
abundant. Mountain passes, such as lookout, lolo, and lost trail,
will be most impacted during this time due to difficult travel
conditions. Confidence is high that up to one foot of new snow is|
likely for terrain above 4000 feet.
For most valley locations, the forecast becomes more difficult.
Winds aloft are approaching the 50-60 knot realm, which would
suggest valleys will be shadowed out of receiving appreciable snow
for much of the day Wednesday. This may change if when the flow
pattern turns northwesterly, which is much more favorable for
valleys to receive accumulating snow. For now, minor snow amounts
are likely across western montana valleys, but we'll be keeping a
close eye on the details as they unfold.
Late next week the pattern remains unsettled with some nice,
partly sunny days in the valleys and frequent mountain showers.
Aviation The stratus clouds in northwest montana are retreating
north as some high cloud moves into the region. Expect increasing
clouds tonight as the next system moves into the area, though
conditions will remainVFR through tomorrow.

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.
