Short term Today through Monday... Northerly flow will continue
through the period as an upper ridge gradually transitions into
the pacific nw. The region will see dry weather with temperatures
warming 2 to 5 degrees each day. Even with the warming, high
temperatures will still be 5-8 degrees below normal on Monday. The
northerly flow aloft will mix to the surface, bringing breezy
conditions each afternoon across open terrain.
Long term Monday night through Saturday... Dry with a warming
trend through Thursday. Little change Friday and Saturday.
Temperatures will be around 5 degrees below normal Monday night and
Tuesday under northerly flow aloft on the east flank of an upper
level ridge nearing the west coast. As the ridge moves inland,|
temperatures will warm to near normal on Wednesday and slightly
above normal on Thursday. Latest model runs show the ridge moving
east of our area Friday and Saturday, replaced by westerly flow
aloft as an upper level trough pushes into b.C. And an upper level
ridge strengthens off the california coast. Models diverge after
Thursday, so there is less confidence in the forecast for Friday and
especially Saturday due to differences in the location and strength
of the ridge.
Aviation Vfr. Mostly clear skies. Surface winds mainly northwest
5-10 kts increasing to 10-15 kts this afternoon. Winds aloft at 10k
feet msl north 15-25 kts.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
