Synopsis
A warming trend is expected this weekend. Temperatures should
drop back down to seasonal values Monday. Rain showers and high
elevation snow showers are possible in the southern sierra nevada
Monday and Tuesday. Outside of the mountains, dry weather will
persist.

Discussion
A cool start start to the day this morning, just few cumulus
clouds developing over parts of the sierra nevada. Otherwise a
sunny and cool day across the central ca interior. Weak
disturbances moving through the flow will maintain a north flow
aloft tonight. This should continue to provide offshore flow with
clear and dry conditions. In addition surface high in the great
basin also providing offshore flow over the high desert and
tehachapi mountains. An upper trough in the N rockies will move ne
allowing a ridge in the epac to build inland over the west coast.

This will bring warmer temperatures across ca for the weekend.

Models in better consensus with the next weather system affecting
the district early next week. Models have trended further west
with the system and move it southward across the entire state from
north to south. Flow turns onshore late Sunday as the upper
trough pushes into N ca.

The upper low closes over central ca as it progresses southward.

There may be enough atmospheric instability and moisture for rain
showers and high elevation snow showers Monday afternoon in the
southern sierra nevada. The low pushes into scal Monday night and
stalls near the mexico border Tuesday. The system may pick up some
remnant tropical moisture and as a result, precipitation chances
will also shift southward. Ensemble means show precipitation
towards the SE ca, thus a few showers cannot be ruled out in the
kern county mountains and desert Tuesday.

A strong upper low for this time of the year may begin to move
southward near the west coast of canada Thursday. This may allow
temperatures to return to seasonal values Thursday. This system
may bring a strong onshore flow with stronger winds and fall
temperatures for next weekend across much of ca.

Aviation
Vfr conditions will prevail at mce, mer, fat, vis and bfl through
at least the next 24 hours.

Air quality issues
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
