Discussion We are enjoying pleasant conditions across the
northern rockies today, with a mix of Sun and clouds and cool
temperatures. A weak weather system will move across southern
canada this evening through Saturday morning. Expect an increase
in clouds in northwest montana, along with a few light rain
showers.

We are expecting winds to increase both Saturday and Sunday
afternoons, as a couple of weak weather systems move through the
region. Westerly winds with gusts of 20-25 mph are expected across
western montana each afternoon, with weaker winds likely across
north central idaho. The weather system Sunday may produce a few
showers along the divide into glacier np through the day.

Temperatures will cool down about 5-10 degrees Sunday and Monday
behind the frontal passage. A few rain showers are again possible
in glacier np and along the divide. By Tuesday, high pressure
will strengthen over the pacific northwest into the northern
rockies. We can expect temperatures in the low to mid 80s under
sunny skies through next Friday (aug 30th).

Aviation Expect a mix of Sun and clouds the rest of today.

Mid and high level clouds will be on the increase this evening
through Saturday morning. A few showers are possible across
northwest montana, especially along the divide.

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.
