Short term Tonight and Monday... Convective activity is beginning
to decrease as sunset approaches. Showers intensity has also
decreased according to radar output. Decreasing showers are now
expected through the rest of the evening and will dwindle to just a
few isolated showers overnight through midday Monday. Showers will
again increase Monday afternoon due to daytime heating. Instability
is not as great as today but still expect the potential for
thunderstorms across most of the forecast area. Forecast has been
updated for decreasing showers overnight.

Prev discussion issued 423 pm pdt Sun may 26 2019
short term... Tonight through Wednesday. Center of the upper low
over northern california today. Several short waves with associated
bands of clouds and showers continue to rotate around the low
into oregon and washington. This will continue through the
afternoon and into the evening before decreasing in coverage
overnight. Radar indicates some stronger showers and a few
thunderstorms and expect this will continue. Activity is moving
west northwest around the northern portion of the low. By Monday
the center of the low is over nevada. Clouds and showers will
continue to move into the region. Isolated thunderstorms possible
in the afternoon. For Tuesday and Wednesday a weak upper level
trough over the pacific northwest. Expect less clouds and
precipitation although weak instability will still produce
scattered showers and isolated thunderstorms mainly over the
mountains in the afternoon. Temperatures will be warmer Tue and
wed with 70s to mid 80s. 94
long term... Wednesday night through Sunday... No major weather
concerns are anticipated through Saturday, but models are
advertising a strong cold front that could bring very windy
conditions to the region on Sunday. From Wednesday night through
Friday, there will be a significant split flow aloft over wa or
associated with a high pressure ridge over western canada and a low
pressure trough over the great basin. This leaves eastern oregon
and far southeast washington under a cyclonic flow where a few weak
impulses will bring a slight chance to a chance of showers. There
may also be a few thunderstorms during the aftn eve, as the air mass
will be marginally unstable. Most of eastern washington will be
under the influence of the high pressure ridge to the north with
skies partly to mostly cloudy. Dry conditions are forecast for
Saturday when the flow becomes westerly and pushes the southern
trough to the east. Sunday's cold front that could bring very
windy conditions is both advertised by the GFS and ecmwf.

Afternoon temperatures will generally range around 65-75 in the
mountains and 75-85 elsewhere. Saturday will likely be the warmest
day, and the lower columbia basin could be in the upper 80s.

Overnight lows will be in the mid 40s to mid 50s for most of the
forecast area--55 to 60 in the lower columbia basin. Both daytime
and nighttime temperatures area about 5-10 degrees above seasonal
average. Wister
aviation... 00z tafs... Showers and thunderstorms will persist up
to sunset and then die out with some partial clearing overnight.

Expect mainlyVFR conditions but could see brief lower conditions in
vicinity of showers and thunderstorms. Will see buildup of showers
again Monday afternoon but mainly over and near the mountains. Winds
generally will remain under 10 kts and then 5-15 kts Monday.

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.
