Synopsis Near normal temperatures with the possibility of
sierra nevada thunderstorms each afternoon and evening for the
next several days.

Discussion A weakness in the upper ridge over the region
helped to trigger some thunderstorms over the sierra yesterday
and continues to move moisture and a few clouds westward across
our area in the cyclonic flow around the feature. Our temperatures
meanwhile are running around 3-6 degrees above 24 hrs ago.

Expect similar thunderstorm activity today and Saturday as the
weak circulation drifts slowly southward. By Sunday, thunderstorm
chances could increase slightly and spread southward through the
sierra as flow turns more southeasterly around the developing low
pressure center and additional moisture is drawn into the region.

This weak low is then progged to swing slowly inland across
southern ca during early next week, maintaining sierra
thunderstorm chances through midweek.

Drier west to northwest flow will then settle in as a more
significant low pressure trough moves into the us west coast,
bringing an end to the convection for the latter part of next
week.

Temperatures are expected to trend slightly upward during the
next couple of days to a few degrees above climo, with triple
digit highs returning to many san joaquin valley and desert
locales. Next week will see temperatures drop back to near or
slightly below seasonal averages under the influence of the
developing low pressure areas.

Aviation
Vfr conditions will prevail across the central ca interior during
the next 24 hours.

Air quality issues
None.

The level of certainty for days 1 and 2 is high.

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.
