Short term Tonight through Sunday...
a weak upper-level ridge is passing over the region today,
bringing sunny skies and allowing the afternoon temperatures to
warm a few degrees more than this time yesterday. West-northwest
flow will develop on Saturday that will create breezy winds for
Saturday afternoon and evening. Winds are expected to remain
breezy over the higher elevation mountains through Saturday
night. Then, anticipate breezy northwest winds to develop again
Sunday, with average gusts to 20-30 mph for valley locations late
Sunday afternoon through Sunday night. Forecast temperatures are
hot for Saturday, but expect a quick cool down to slightly below
normal for Sunday.
Long term Sunday night through Wednesday... Dry northwest flow
persists on Monday as temperatures remain a couple degrees below
normal. Temperatures over the intermountain west will rise to above
normal mid-week as tropical storm ivo progresses northward along
the pacific coast, shifting the pattern to southwest flow aloft.
Residual moisture from the weakening storm is expected to increase|
cloud cover, but rainfall is not expected with this system.
Wednesday night through Friday night... Clear to partly cloudy skies
are the overall expected conditions across the region as relatively
dry ridging is expected to prevail. However, look for the
possibility of afternoon and early evening thunderstorms (mainly
along the mountain ranges), fueled by moisture remnants from a
dissolved tropical storm caught up in the southwesterly flow and
slowly pushing across the area. Hot temperatures are once again
expected with highs measuring in around 5 degrees above normal with
lows dropping down to around two degrees above normal.
Aviation Vfr under scattered passing high clouds. Increasing
cloud coverage overnight. Surface winds: generally west to northwest
10 kts or less. Winds aloft at 10k feet msl: northwest 10-20 kts.
Weekend outlook...VFR. Mostly clear. West to northwest surface winds
10-20 kts with gusts up to 25 kts on Sunday.

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.
