Short term Morning update... The pacific northwest will remain
under a low amplitude upper ridge through tonight. As such will see
fair and mostly dry conditions with varying amounts of mid and high
level cloudiness. Winds will be mainly 10 mph or less. The exception
will be over portions of the grande ronde valley, wallowa county,
the blue mountains, and the blue mountain foothills. These areas
should see gusty winds of 10 to 25 mph at times. Overall the
forecast package is on track. Updates focused on adjustments to
winds, sky cover and snow levels for today and tonight, and a few
high temps for this afternoon. 90

Long term Previous discussion... 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.

Aviation 18z tafs...VFR conditions will persist through the next
24 hours. A flat ridge will persist through Sunday with abundant mid
and high level clouds passing through the region. Winds will be
light through the period at all TAF sites. 76

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.
