Short term Today through Saturday night... An upper ridge, with an
axis roughly along 130w longitude, will gradually shift east through
this period. By late Saturday night early Sunday morning the ridge
axis will extend along the cascade crest. As such the pacific
northwest will remain under a dry northwest flow today through
Saturday. This flow will become more westerly, and lighter Saturday
night. Thus will see fair and dry conditions with very little cloud
cover (only very thin cirrus if any). Temps will warm each day, with
high temps running 8 to 12 degrees above seasonal by Saturday
afternoon. Winds at night will be mainly drainage (down slope down
valley) and light. Morning winds will be generally light and
variable. Afternoon winds will mainly be from northerly through
easterly directions with speeds running between 5 and 15 mph. 90

Long term Sunday through Friday... High pressure aloft will
persist on Sunday and Monday with sinking air under the high
pressure ridge. This will cause very warm to hot conditions. There
will be an increase in moisture and instability on Monday. The
amount of moisture and instability on Sunday will not be enough to
trigger afternoon thunderstorms due to a lack of deep layer moisture
on Sunday with very dry air in the lower levels. Therefore decided
to not to include thunderstorms on Sunday. There may be isolated
thunderstorms in central oregon on Sunday evening, but there will be
a better chance on Monday. Sunday will be the hottest day with high
temperatures in the 90s to near 100, and then a cooling trend will
begin on Monday. Have added thunderstorms in the forecast on
Monday... Mainly in the afternoon and evening as the amount of
moisture combined with instability increases... But thunderstorms on
Monday will be only a slight chance. An upper trough will move into
the region on Monday afternoon and evening with a cold front marine
push. This will act as a trigger to spawn afternoon and evening
thunderstorms on Monday. Dry and stable air will return to the cwa
on Tuesday and persist through the rest of the long term
period... I.E. Tuesday through Friday. Temperatures will be slightly
cooler on Monday and then considerably cooler on Tuesday. High
temperatures will be in the 80s on Tuesday and Wednesday. Then
Thursday and Friday will have slightly warmer temperatures... But
there will not be a strong warming trend due to an upper trough that
will longer over the CWA through Friday. It will become breezy to
windy on Monday late afternoon and evening... And again on Tuesday
afternoon and evening. This may cause fire weather concerns due to
the winds combined with possible lightning on Monday and then low
humidities on Tuesday. Winds will then become light again by late
Tuesday night and persist through Friday. 88

Aviation 12z tafs...VFR conditions with mostly clear skies, light
winds and stable conditions will prevail through the next 24 hours.

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.
