Discussion Strong westerly winds from a passing cold front
are starting to materialize in northwest montana and will continue
to spread across the rest of the northern rockies through the
evening hours. Winds will likely be their strongest as the actual
cold front moves through the region between 6 and 9 pm north to
south. Some mountain wave winds may occur and impact the
bitterroot valley this evening with brief gusts of up to 45 mph
which could cause some local tree damage or brief power outages.
If the strongest winds persist for a while then a high wind
warning may be warranted.
Another potential impact with this cold front will be the
lowering snow levels. Area passes, such as lolo, lost trail,
macdonald, and homestake passes could see a brief period of
moderate to heavy snow this evening and overnight. The main
impact will likely be reduced visibility. Due to warm road
temperatures if snow accumulates it should melt relatively
Snow levels will lower to around 3500 feet behind the front.
Scattered snow showers with little accumulations are expected
Friday morning. Dry conditions with an increase in Sun will occur
Friday afternoon under a building weak ridge. This ridge will
likely persist through Saturday night. Probably the biggest
potential impact for commuters and holiday travelers this weekend
will be the increasing potential for fog with very low visibility
Saturday morning and possibly Saturday night.|
Another strong cold front is anticipated to swing through the
northern rockies late Sunday into Sunday night. Ahead of the front
southerly winds will develop causing temperatures to potentially
warm to above normal readings. The models waver slightly on the
timing of the front, but anticipate a burst of precipitation along
the front. Gusty westerly winds could be a concern once again
along and behind the front. Snow levels will be relatively high so
any impactful snow will be limited to the higher terrain and
potential mountain passes.
The models diverge some for the first part of next week, but
temperatures should be near seasonal with lingering shower
Aviation Mild conditions across the area but with strong
westerly flow associated with an approaching cold front. Areas of
mountain obscuration will continue through tonight... Along with
the turbulence associated with the windy and well mixed
conditions. Expect less fog for Friday morning than on recent

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.
