Short term Tonight through Friday... An upper trough dropping
into the pacific northwest will bring a period of light snow to
the region tonight into Thursday. Models have been consistent in
showing a band of snow developing across southeast oregon tonight,
transitioning into southwest idaho by sunrise. However confidence
in the track of the developing precipitation band is lowest as it
moves into southwest idaho. The heaviest snow will fall across a
fairly narrow area from s-central harney and malhuer counties,
into the owyhee mountains. In southwest idaho the focus of
snowfall will cross the treasure valley between ontario and
mountain home and extend northeastward into the central boise
mountains. This system will be working with a limited amount of
moisture (pw values are in the 10-20th percentile during this
event) so have weighted QPF (and thus snowfall) amounts toward
model solutions with lower amounts. Temperatures will likely warm
above freezing at sites below 4000 feet Wednesday afternoon,
though precipitation type will stay all snow through the event.
Have issued an advisory for southern and western zones starting
The upper low moves into eastern idaho Thursday night, which will
cut off the precipitation. Friday is dry but continued cold under
a passing short wave ridge. Temperatures continue to run 10-15
degrees below normal through Friday.
Long term Friday night through Wednesday... The northern
intermountain region will remain under northwest flow aloft, with
unsettled weather and below normal temperatures. The next upper
level trough from the gulf of alaska will spread snow showers
across our area Saturday and Saturday night. Snowfall in the
valleys is expected to be around an inch, with heavier amounts in
the mountains. On Sunday lower elevations of southwest idaho and|
southeast oregon will see brief improvement, with snow showers
decreasing to isolated and partly cloudy skies. Temperatures will
average from 5 to 10 degrees below normal.
Monday evening through Thursday morning... Active troughing
pattern holding on and continuing to facilitate the ushering in of
periodic trough-ridge couplets into and across the cwa. The gfs
and ec models somewhat agree at the start then quickly part ways
by Tuesday evening with the GFS being the more active. Mostly
cloudy conditions with widespread snow during most of the time
frame associated with these translating disturbances with brief
periods of sunnier skies and milder weather in between. Mild
northwest winds for the most part becoming breezy with passing
frontal systems. Temperatures averaging around 5-8 degrees below
Aviation Vfr through this evening except for local MVFR
ceilings with isolated snow showers. Deteriorating conditions after
06z with snow becoming widespread across southeast oregon and the
central idaho mountains and continuing through Thursday. On Thursday
snow spreading east through the snake river valley, but decreasing
to isolated showers at kbno and kbke. Surface winds variable under
10 kts, then variable 5-15 kts after 06z. Winds aloft at 10k ft msl
southwest 10-20 kts.

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.
