Short term An upper trough will swing onto the west coast on
Wednesday. Clouds and a chance of showers increase across
southern harney and malheur counties and far southwest idaho
Wednesday afternoon with areas to the north remaining dry. The low
center in the base of the trough will track through nv on
Thursday, while the trailing upper trough extends back to the
oregon coast. This will keep a chance of showers over southeast
oregon and along the id nv border through Thursday. A sharp
gradient in the clouds and precipitation will keep dry conditions
across east-central oregon and the snake plain and west-central
mountains of idaho through the period. Temperatures are around 10
degrees above normal Wednesday, cooling to near normal on
Long term Thursday night through Sunday... As a low pressure
system passes to the south, lingering rain showers will persist
along the nv border through Friday as temperatures remain well
above normal. The next system approaches early Saturday, with
increased winds and widespread rain and snow showers blanketing
the region over the weekend. Snow levels will drop to 3500-4500 ft
msl by Sunday morning, resulting in rain in the valleys and snow
in higher elevations. Temperatures will drop to right around|
normal by Saturday, but will bounce back after a slight ridge
builds in behind the exiting precip.
Sunday night through Tuesday night... Rapidly changing weather is
expected throughout most of the period as a progressive weather
pattern sets up. Milder conditions will start the period as a fast
moving drier, upper ridge sweeps through. But by late Tuesday
evening more unsettled weather is expected to return and spread
from west to east in advance of an approaching, developing upper
level disturbance. When this occurs, rain showers and breezy
conditions are expected across most of the region with snow
showers confined to the mountains (higher elevations). These
conditions should linger throughout the remainder of the period.
Look for a warming trend as high and low temperatures measure in
around 5 to 8 degrees above normal.
Aviation Vfr with mostly clear skies. Surface winds east-
southeast 10-20 kts. Winds aloft near 10k ft msl: east 20-25 kts.

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.
