Update
Not much to speak of tonight, except increasing high clouds in
advance of an approaching cold front. Made adjustments to cloud
cover and changed winds tonight and early Wednesday based on the
latest guidance, also some minor adjustments to temps.

Aviation
06z tafs... .Vfr conditions through the TAF period. Quiet tonight.

Winds should slowly decrease overnight but remain quite gusty at
dls. Wind will increase again on Wednesday with gusts 15 to 30 kts
possible in the afternoon and evening as a cold front crosses the
area from west to east. The best chance of any showers would be at
dls, rdm and bdn but not heavy enough to reduce CIGS or vsbys.

However, by afternoon at dls rdm, bdn, ykm and evening elsewhere a
midlevel cig is anticipated. Some lower CIGS are psbl, but
confidence is not high enough to forecast at this time.

aviation...

00z tafs...VFR conditions to continue through tonight and into
Wednesday. Mainly high clouds tonight and early Wednesday will
thicken and lower, especially for dls, rdm and bdn with a midlevel
cig by afternoon. Otherwise, gusty winds will continue through the
evening before decreasing to mainly 10 kts or less. Gusts will
return on Wednesday mainly 15 t0 20 kts at pdt, bdn and rdm and up
to 25 kts at dls.

short term... Tonight through Friday night... An upper level ridge of
high pressure will be over the region tonight with some high clouds
passing through the area. The ridge will move off to the east on
Wednesday as an upper level trough moves inland and pushes a cold
front through the forecast area in the afternoon and evening. Main
impact of the front will be some increasing westerly winds behind
the front. There will also be some rain showers ahead of the front
and a slight chance of thunderstorms over eastern grant and wallowa
counties through the evening. Cooler air will filter into the region
Wednesday night and Thursday as the upper level trough passes over
the region. There will be some lingering locally breezy conditions
Thursday along the east slope of the cascades. Temperatures will
begin to rebound Friday as a dry flat westerly flow returns.

Long term... Saturday through Tuesday... A quiet,dry pattern sets up
for the weekend and early next week. Dominant flow across the region
will be zonal northwesterly through at least next Tuesday. This will
keep temperatures near normal with afternoon highs in the mid to
upper 80s for the lower elevations and 70s expected for the
mountains. Locally breezy winds sustained between 10-20 mph with
gusts ~30 mph are expected for Saturday and Sunday afternoon through
the columbia river gorge, columbia basin, and kittitas valley and
will diminish heading into early next week. Richards

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.
