Short term A closed low over northern utah is bringing wrap
around showers to far eastern oregon, including wallowa and union
counties. Meanwhile, isolated showers and thunderstorms have
developed along the washington and northern oregon cascades ahead
of an approaching shortwave trough from the north. A decaying
thunderstorm is currently present between the dalles and hood
river. Winds are breezy near the cascades and the eastern columbia
river gorge. After midnight, any showers will be isolated and
winds will decrease.

The shortwave trough from b.C. Will become a deeper trough as it
travels over washington on Friday. The air mass will be more
unstable with a better chance of thunderstorms, although any
storms that develop will likely be pulsating weak storms due to
the lack of shear and capes less than 300 j kg. In addition,
westerly surface winds will increase on Friday with gusts 30-40
mph in some areas. In the eastern columbia river gorge and north
central oregon, gusts to 45 mph can be expected in some wind-prone
areas. Wister

Aviation 06z tafs... Sct-bkn 050-100 with higher level clouds will
continue through tonight and most of Friday. Isolated to scattered
showers as well as isolated thunderstorms will develop Friday, and
kpdt and kalw will have the best potential to observe afternoon or
evening convection. Winds will increase during the day on Friday,
and most TAF sites will have 10-15 knot winds gusting to 25-30
knots. At kdls, gusts to 35 knots are possible on Friday. Wister

short term... Friday night through Sunday... Showers will taper off
and mostly end by late evening Friday. Saturday looks to be
relatively quiet with just a few mountain showers. It does not
look particularly unstable so do not have thunderstorms mentioned
at this time. On Sunday precipitation chances will increase in the
afternoon over the central and eastern mountains and highlands
with enough instability for a few afternoon thunderstorms. 78
long term... Sunday night through Thursday. Upper low over
california nevada Sunday night will continue to push clouds and
showers into the forecast area especially the southern portion. By
Monday the low is moving well off to the southeast and upper ridge
is starting to build offshore with northerly flow over the region.

Should have decreasing clouds with just a chance of showers over the
mountains. Models not in complete agreement for mid week though
overall trend appears to be a ridge building over the area. This
will provide partly cloudy skies and warming temperatures. Lower
elevations of the columbia basin and valleys will see highs getting
into the 80s. No significant winds expected through the period. 94

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.
