Synopsis A weak weather system will affect mainly northern
washington and the mountains tonight through Friday. A upper
level ridge result in dry conditions and patchy night and morning
fog this weekend into early next week. The next weather system may
bring wet weather back to the region by mid to late next week.

Short term today through Friday night Just a few light rain
showers continue to drift SE across the northwestern portions of
the state ahead of a weak shortwave. This wave will brush the
region tonight into Friday and result in some additional shower
activity, mainly focused across the mountains. Some light showers
will be possible in the lowlands, though significant rain
accumulations are not expected. Skies are expected to clear from
north to south in the wake of this system Friday into Friday
night. -wolcott-

Long term Saturday through Wednesday An sharp upper level
ridge will develop Friday into Saturday resulting in dry
conditions across the region. Areas of morning fog will be
possible along with areas of sub-freezing morning lows. Otherwise,
quiescent conditions are expected this weekend into early next
week.

The main change in the long term period today was decreasing
precipitation chances Tuesday as the possible pattern change
appears to be slightly delayed. In any case, precipitation are
likely to increase as we head toward the middle or latter part of
the week. There is considerable uncertainty in any details of this
pattern change, so please stay tuned as we head into the
thanksgiving week. -wolcott-

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
