Stable conditions from high pressure over the northern rockies.
As a result, the valley smoke has been very slow to disperse,
keeping degraded air quality in-place. Mid-level smoke from
oregon wildfires is also moving overhead, adding to the smoke
content in our view.
As high pressure shifts eastward on Wednesday, isolated showers and
thunderstorms are possible in north-central idaho and southwest
montana by late afternoon. Gusty outflow winds and dry lightning
will be the main concerns for this initial round.
Heading into Wednesday night, winds will become increasingly
breezy, and showers and thunderstorms will spread across northwest
west-central montana and north-central idaho. These storms have a
better chance at producing some rainfall, but widespread wetting
rains are not expected. Lightning and wind activity will be|
unfavorable for wildfires.
Scattered showers thunderstorms will shift eastward through west-
central southwest mt along a quick-moving cold front Thursday
morning through Thursday night. Again, gusty winds and lightning
will be the main threats. Wildfires in the region are anticipated
to stay fairly active during these breezy, unstable conditions.
A strong, warm high pressure pattern will return by the weekend,
allowing dry and smokey conditions to return to the area.
Aviation Warm and stable conditions are in place today,
keeping low-level valley smoke from dispersing too much. Mid-level
smoke from oregon is also moving overhead. Kmso and kbtm, as well
as kgic, will experience visibility reductions in the evening and
overnight as stable conditions persist into morning.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. 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.
