Discussion High pressure will continue to dominate the weather
pattern over the northern rockies for the next few days.
Temperatures today will be about 5 degrees warmer than yesterday,
peaking in the upper 80s in most locations. Tuesday and Wednesday,
high temps will peak in the low to mid 90s for valleys of central
idaho into western montana, with a few select valleys still
remaining in the 80s. Overall, a very summery mid-week.
A cold front is still anticipated to cross the region Wednesday
night through the day Thursday, bringing with it a widespread
increase in breezy winds and the chance for precipitation.
Rainfall will be most likely along the interstate 90 corridor and
northward to the canadian border. South of this area, very light
rain, if any, is likely. This is by no means a very strong cold
front, but a noticeable temperature drop will be felt Thursday,|
particularly across northwest montana. High temps will average in
the 70s across central idaho and western montana. Those with plans
to be in high terrain, especially in around glacier national
park, should plan for chilly, wet conditions.
Conditions look like they will bounce back somewhat on Friday and
Saturday, with temperatures returning to the 80s across the
region. Dry mild days followed by cool nights should be expected
through the weekend.
Aviation Fair flying conditions are expected for the next 24
hours across the northern rockies. Kmso, kgpi and kbtm should
anticipate some gusty westerly winds between 19 2100z through
20 0200z, and again between 20 2100z through 21 0200z.

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.
