Synopsis
Temperatures near to above normal with daily afternoon evening
mountain thunderstorms.

Discussion
High pressure will shift off to the east this weekend as upper
level troughing moves in across the area into early next week.

Onshore flow will increase with decreasing heights and will lead
to a slight cooling trend through the weekend. Temperatures will
still remain at least a few degrees above normal with hottest
readings across the northern sac valley which will likely remain
above the century mark. Breezy winds excepted through the delta
as marine layer deepens and delta breeze strengthens. Moisture
will continue to be drawn north, with a daily chance of
afternoon evening thunderstorms near the sierra crest and possibly
the coastal range by Monday.

.Extended discussion (Tuesday through Friday)
a low pressure lingering off the coast of california will keep
temperatures right around average for the long term forecast
period starting Tuesday and through the end of next week.

Afternoon showers and thunderstorms for the mountains are possible
as the disturbance moves slowly east on Tuesday and Wednesday.

Once the trough base aloft moves across northern california,
mountain storm chances will diminish towards the end of next week.

Aviation
Vfr conditions the next 24 hours at the TAF sites. Winds under 10
knots except in the delta where gusts to 30 knots will be
possible. Afternoon thunderstorms and CB possible over the sierra
this afternoon and through the early evening.

Sto watches warnings advisories
None.

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.
