Discussion A weather system and associated cold front will
sweep across north central idaho early this evening and western
montana overnight. Initially, the snow level is above most
mountain passes, but will lower overnight with mainly lolo, lost
trail, william's summit, and possibly homestake seeing some snow.
The impact should be a short period of slush or wet snow on the
roadway later tonight and early Saturday morning. Otherwise, rain
showers should be on the light to moderate side with little or no
A relatively cool and breezy period is expected Saturday as a
moist and unstable atmosphere covers the northern rockies.
Sunday brings weak high pressure and a dry period with seasonal
high temperatures into the 50s. The ridge aloft could allow for
some patchy fog during the early morning hours, but heating after
sunrise would quickly mix out fog that does form.
Sunday night into Monday morning, another wet system will move
over the region. The main energy with this trough will be to the
south, so precipitation rates and accumulation will again be on
the light side. However, clearwater and idaho county could see
another 0.25 to 0.50 inches of moisture over 24 hours, so|
saturated soils could again become more prone to isolated mud and
rockslides. Scattered showers, mainly in the terrain, linger on
Tuesday and Wednesday in westerly flow.
A more robust system could bring heavier rain amounts on
Wednesday night. Models advertise a short burst of pacific
moisture before a shortwave trough moves through Thursday. But
these type of systems have trended south in recent weeks, so the
confidence in precipitation amounts is low at this time.
Aviation The northern rockies will see thickening clouds and
lowering ceilings into the evening as the next weather system
approaches. North central idaho will see light to moderate rain
showers first, into this evening. Western montana aviation sites
kmso and kgpi should see showers this evening and overnight. The
frontal/weather system will not impact kbtm with showers until
around or after midnight. The main impacts of the showers should
be lowering of ceilings and visibility in the more moderate
precipitation showers and increasing terrain obscurations.
Southwesterly breezes of 20-30 kts ahead of the showers can be
expected for kbtm into this evening.

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.
