Short term Tonight through Monday... A cold front is slowly moving
across the forecast area at this time. The front will exit the
forecast area later this evening. Precipitation ahead of the front
will be a light steady rain except for snow in the higher mountains
in which a winter weather advisory continues. Behind the front there
will be partial clearing and a few showers continuing overnight
mainly over the mountains. The upper level trough behind the front
will pass over the forecast area on Saturday with enough instability
to generate some more showers mainly over the eastern mountains
before conditions turn dry for Saturday night. The next weather
system will quickly arrive Sunday as a warm front then followed by a
cold front Sunday night. Showers will continue on Monday due to
instability associated with the upper level trough passage behind
the front.

Long term Monday night through Friday... The extended period
starts with a weak warm front with mainly orographically induced
rain moving across the region Monday night. As such most of the rain
Monday night will be in the mountains, with most of the lower
elevations remaining dry. The warm front becomes better organized by
daybreak on Tuesday through Tuesday night for higher pops yielding a
chance of valley rain and a chance of mountain snow with the snow
level rising from 3500 to 4500 feet agl along the east slopes of
the washington cascades and rising to 4500-5500 feet overnight in the
mountains of central and NE oregon. By Wednesday afternoon snow
levels rise to around 5000 feet agl along the east slopes of the
washington cascades and to 5000-6000 feet agl in the mountains of
central oregon while snow levels in NE oregon remain near 5000 feet
agl through Wednesday afternoon.

The weather system moving into CWA Wednesday morning has good
dynamic lift associated with the left exit region of an upper level
jet stream resulting in rain likely in many areas from daybreak
through Wednesday afternoon. Wednesday night and Thursday a
mid/upper level trough moves southeastward through the region
producing strong dynamic lift and pushing a cold front across
forecast area for rain likely in the northern blue mountains and a
chance of rain elsewhere. Thursday night through Friday afternoon
high pressure will be moving through the interior pacific northwest
for dry conditions. Polan

Aviation 00z tafs...VFR conditions over the next 24 hours. A cold
front has already moved through all TAF sites this afternoon for
partial clearing expected this evening and rain/showers have ended,
except that the kpdt radar still shows a line of showers moving over
the foothills of the blue mountains so kpdt and kalw have vcsh until
02z/25th. Mid level clouds will increase with bases lowering
overnight with cloud bases of 5000-1000 ft agl. West winds of 10-15
kts into this evening will decrease overnight and then increase to 5-
12 kts during the day on Saturday. Polan

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
