Short term Today through Monday. A low amplitude upper ridge will
be over the region through Sunday. This will result in dry
conditions and mild temperatures. There will be some cloudiness
especially north. Winds will be mostly light except it will be a bit
breezy in the grande ronde valley. Late in the day Sunday and
especially Sunday evening precipitation will begin to spread east of
the cascades as a shortwave trough flattens the upper ridge. Snow
levels will initially be around 3000 feet along the east slopes of
the washington cascades... So some snow will be possible over the
higher elevations before snow levels rise Sunday night. After 06z
Monday precipitation... Mostly rain will spread across the entire
forecast area. Snow levels will be high enough such that winter
highlights are not anticipated. There could be some gusty southerly
winds along the blue mountain foothills and along the oregon cascade
east slopes Sunday night. On Monday a weak boundary will sag
southward across the area pushing the rain southward out of
washington and eventually northern oregon by late in the day... But
still good chances for rain all day central oregon. It will be
rather warm on Monday with highs 50-60 lower elevations and mostly
40s in the mountains. 78

Long term Monday night through Saturday... Models are in fairly
good agreement in the extended forecast from Monday night through
Thursday night. There will be an upper ridge over the inland
northwest with a moist southwest flow on the back side of the ridge
over the forecast area. There will be several warm fronts moving up
over the CWA during this period keeping a chance to likely
precipitation through the period. The wettest days will be from
Tuesday through Wednesday with a very moist warm front. The
southwest flow will cause very mild temperatures. Precipitation
probabilities will be in the chance to likely category with the best
chances in the mountains and somewhat less in the lower elevation.

Snow levels will be fairly high so snow will will be confined to the
higher mountains with little to no accumulation over the passes.

Snow levels will range from 5000 feet Monday night rising to around
10,000 feet by Wednesday and Thursday. A cold front will then move
through the region Thursday night and early Friday. Models begin to
diverge by this time but all are still showing a cold front moving
through the cwa. Snow levels will come back down to around 5000-6000
feet by Friday morning. The precipitation chance will also be
decreasing during this time... Especially over the lower elevations.

For Friday night into Saturday the models diverge from each other
more significantly but the general consensus is that another ridge
will develop over the inland northwest with a moist southwest flow
over the CWA again and showery unsettled weather continuing. 88

Aviation 12z tafs...VFR conditions will persist through the next
24 hours. There will be some lower to mid level clouds... Especially
over the higher terrain with ceilings around 5k-7k feet msl. Winds
will be light through the period at all TAF sites. 88

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.
