Update A weak wave and trough is exiting the area this evening
and a northwesterly flow is setting up behind it. The trough had
little moisture or energy. So, I took out the showers along the
washington cascade crest this evening as radar and webcams showed
no precipitation and just some scattered flat cumulus. Also made
some cloud cover adjustments to match up to satellite imagery
better. With less cloud cover, adjusted overnight temperatures
down a degree or so. Winds have been decreasing in the last hour
or two as expected. Made a few minor adjustments there as well.

Also bumped up winds a bit tomorrow afternoon as even stronger
winds are expected then. Forecast update already out. Perry

Aviation 06z tafs... Scattered mid level clouds will continue
this evening before dissipating overnight. Scattered to broken high
level clouds above 20k feet will be present overnight. Tomorrow
afternoon and evening scattered to broken ceilings will return at 4-
8k feet with scattered to broken mid clouds at 10-15k feet. Winds
will remain below 12 kts tonight. Winds will increase again after
15z tomorrow morning and reach 10-20 kts with gusts to 30 kts at all
taf sites from late morning through early evening before decreasing
after 04z. Perry

short term... Tonight through Friday... Broad west to northwest flow
will be over the area through the forecast period. This will keep
the region dry and warm except for some clouds and occasional very
light rain along the immediate cascade crest. It will be breezy in
the cascade gaps each afternoon and evening with winds peaking
Thursday afternoon and evening. Winds could be 25-35 mph with gusts
to 40 mph in the columbia gorge and kittitas valley during this
time. This could present some localized fire weather concerns
Thursday. High temperatures Wednesday and Thursday will be in the
mid 80s in the lower elevations with mid 60s to mid 70s in the
mountains. It will be 3-5 degrees cooler on Friday. Overnight lows
will be in the mid 50s to lower 60s with mostly 40s in the
mountains and high plateaus.

Long term... Friday night through Tuesday. Main impacts for the
extended will be much warmer temperatures. Upper level trough will
be moving east of the area Friday night. Clearing skies and
decreasing winds. Upper level ridge will then build northward into
the region over the weekend with warming temperatures and mainly
clear skies. For Monday and Tuesday strong upper high over the
southwest and an upper low offshore. This will maintain a southwest
flow aloft. High temperatures will be in the upper 80s and 90s.

Models showing weak instability with a few short waves passing
through. At this point will keep thunderstorms out of the forecast.

Partly cloudy skies with some buildups over the mountains. 94

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.
