Synopsis
Expect cool, breezy, and showery weather for Thursday and Friday.

Mountain passes could see a few inches of snow overnight Thursday
into Friday. A ridge of high pressure moves in Saturday
delivering a brief dry period before more unsettled weather moves
in Sunday and into early next week. Next Wednesday dry conditions
with average temperatures are expected.

Discussion
Morning update: forecast generally on track with only minor
updates made to temperatures and precipitation chances. Water
vapor imagery shows a disturbance dropping through from the north
keeping scattered showers alive early this morning. Showers are
expected to expand in coverage by this afternoon and continue into
the evening hours, particularly across far eastern washington and
the idaho panhandle. Cameras show some snow fell at our higher
elevations such as lookout and stevens pass overnight and early
this morning but travel impacts are expected to remain minimal as
the late april Sun angle takes hold. Southwest and westerly winds
will also remain elevated thru the afternoon hours. /kalin

Aviation
12z tafs: though evening thunderstorms helped to moisten the
boundary layer at kgeg/ksff/kcoe overnight, steady southwest winds
are keeping any fog from forming. A disturbance moving through
the area today will bring the return of rain showers later morning
into the afternoon for all terminals but kmwh and keat. Southwest
winds will remain breezy into the afternoon. Rain chances linger
into Friday morning for klws and kpuw. For kmwh/keat high
confidence of continuedVFR conditions. Bw

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
