Short term This afternoon through Sunday night. Moist, unstable
northwest flow will result in upslope showers along the cascades
with scattered showers over the eastern mountains through this
evening. Snow levels fluctuating around 5000 ft. An outside shot
for rain shower out in the basin, but will likely stay dry with
the with the westerly flow off the cascades. Localized breezy
winds in the basin this afternoon will die off after sundown. A
stronger short-wave digs southeast across the pacnw late tonight
through tomorrow night. Rain and mountain snow likely in all areas
between midnight and tomorrow afternoon. Significant upslope flow
will bring hefty amounts of QPF for the cascades, the blue
mountains, and the wallowas--between 0.50 inch to 1.0 inch of
liquid precipitation. Snow levels will lower during the day and
will fall to near 4000 feet by tomorrow night. Precipitation will
taper off after the frontal passage, therefore the heaviest snow
accumulations will be in the higher elevations. Currently a winter
storm warning for northern blues and winter weather advisory for
wallowa county is in effect for late tonight through late Saturday
night.

Winds tomorrow will be another concern. Strong winds aloft and a
tightening pressure gradient behind a surface cold front will
result in breezy to windy conditions across much of the region,
especially over northern or. For areas along the wa or border,
particularly from mosier to milton-freewater, sustained winds of
25-30 gusting to 45 mph are likely. A wind advisory is in effect
tomorrow for the eastern columbia gorge and for a good portion of
north-central or.

The system departs late tomorrow night but moist, northwest flow
continues in its wake with mountain snow showers expected through
Sunday night with a chance of rain showers in the basin. One to
two inches of new snow possible for elevations above 4000 feet.

Long term Monday through Friday. Northwest flow will prevail
over the area through much of the period as a ridge of high pressure
remains offshore. Several rounds of moisture will move through in the
flow, producing mainly mountain showers Monday and Tuesday. A
shortwave will be dropping south through idaho on Wednesday,
clipping the northeast corner of oregon with a few showers and
bringing in some cooler air. The ridge is expected to move inland
Thursday and Friday with dry conditions and seasonal temperatures. 93

Aviation 18z tafs...VFR conditions will prevail through the
forecast period. Sct-bkn clouds 4-6 thousand feet agl will continue
ahead of the next systems. Rain will spread east of the cascades by
early evening and spread across the region overnight. There could be
some LCL MVFR CIGS vsbys in the heavier rain tonight. Rain will be
decrease after 15z with bkn-ovc clouds 040-050. Winds will be sw-w
at 10-20 kt with some higher gusts diminishing overnight, but then
increase after 15z on Saturday to 15-25 with higher gusts. 93

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.
