Cool and wet conditions today through Friday...

Discussion A large upper level closed low weather system will
impact the northern rockies today and through Saturday. Scattered
rain and higher mountain snow showers currently across central
idaho and west central montana are expected to increase in
coverage through the day. Temperatures will continue to cool
today resulting in lowering snow levels to around 5000-6000 feet.

1-2" of wet snow are possible across the bitterroot and
clearwater mountains. These expected snow levels will impact lost
trail pass, skalkaho pass and georgetown lake this morning.

Valleys will struggle to reach 60 degrees across western montana.

The center of this weather system will move eastward Friday but
wrap around moisture will impact primarily northwest montana
Friday and Saturday. Glacier np can expect snow impacts above
6000 feet. Folks hiking, camping or planning other outdoor
activities should prepare for a couple of days of raw, cool and
possible snowy conditions today and especially Friday.

The upper low will exit the region later Saturday and Sunday. We
can expect temperatures to gradually rise to around 70 Monday and
Tuesday then to near normal readings in the mid 70s by the middle
of next week. An increase in a moist southwest flow will bring the
potential for thunderstorm activity the middle to end of next
week.

Aviation Scattered showers will impact all terminals this
morning. We are expecting an increase in coverage of rain and
mountain snow showers through Friday. Mountain obscurations and
visibilities from low stratus are expected to impact kmso and
kgpi through tonight.

Mso watches warnings advisories
Mt... Winter weather advisory until 11 am mdt this morning above 5500
feet for the bitterroot sapphire mountains.

Id... None.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
