Short term Tonight through Saturday... Vigorous cold front is
located in eastern idaho with a significant push of colder air
resulting in northwest winds of 25 to 35 mph with higher gusts
across most of SE oregon and SW idaho. The winds are expected to
increase further through late this afternoon, and are expected to
at least briefly reach high wind speeds (at least 40 mph) and/or
gusts (up to 60 mph) from near mountain home south to the nevada
border. The winds will gradually subside overnight.
Showers (mixed with snow in the lower valleys) associated with an
upper trough will continue mainly over SW idaho this afternoon
then decrease overnight as the trough transitions to an upper low
which will then shift to our southeast. North-northwest flow
aloft in the vicinity of the low will allow the snow showers to
persist near the id/nv border tonight for additional snow
accumulations. Showers may linger near the id/nv border through
Friday afternoon while dry weather returns to the remainder of
the region. Winds will remain gusty on Friday, but not as strong
as today. An upper ridge will build into the area Friday night and
Saturday resulting in dry weather, light winds, and near normal
Long term Saturday night through Thursday... A shortwave passes
just north of our area Saturday night into Sunday. Chances of
precipitation remain for the northern portions of the cwa. Sunday
night another wave passes through the region. This one is a little
more potent and will bring wider chances of precipitation to the
area. Snow levels with this wave do drop below 4000 feet msl. By
Monday night an upper level ridge starts to build in which will
bring snow levels back up above 5000 feet msl. Models have slowed
down the progression of the next pacific system quite a bit from|
yesterday, but are in much better alignment. Precipitation starts
to hit SE oregon zones by Thursday morning and continues to push
eastward throughout the day. Temperatures start above normal for
Sunday then drop to right at or below normal for Monday. Once the
ridge begins to build in Monday night temperatures climb to above
normal again and remain so through the end of the period.
Aviation Vfr with MVFR/ifr within heavy showers and higher

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.
