Synopsis Near normal temperatures with the possibility of
sierra nevada thunderstorms each afternoon and evening through the
forecast.

Discussion Upper level high pressure over the eastern pacific
began to build east into california this afternoon... Resulting in
a warming trend across the area. Temperatures across the area were
generally between 5 and 8 degrees warmer compared to 24 hours ago
and are expected to climb to seasonable normals.

Cumulus clouds are building over the sierra nevada... But still
remain pretty flat. One small shower was observed near yosemite
national park in the past hour... But quickly dissipated. The high
res arw and nmm indicate an uptick in activity through the early
evening hours. Any storms that do form will move to the west
southwest. This may mean some clouds will drift into the foothills
and possibly the valley this evening. Out of the next 5 or so
days... Today looks like the least amount of thunderstorms activity
over the sierra.

Continued subtle warming is expected Friday and Saturday... With
temperatures a few degrees above normal. These are also the two
days where a few san joaquin valley locations could see
temperatures reach the triple digits.

Thunderstorms will be possible both Friday and
Saturday... Especially from sequoia national park northward.

An upper low will develop off the central and southern california
coastline on Sunday and begin to move slowly southwest into
Tuesday. This will increase thunderstorm coverage over the sierra
nevada and possibly into the desert Sunday into the first part of
the week. We will continue to monitor this closely and update the
forecast accordingly.

Last... But not least... The forecast still calls for sunny skies
across the valley and maybe just a few clouds over the mountains
for the partial solar eclipse. We were initally a bit concerned
with the upper low forming offshore... However with the southwest
movement... It should not be an issue.

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

Air quality issues
None.

Certainty
The level of certainty for days 1 and 2 is medium.

The level of certainty for days 3 through 7 is medium.

Certainty levels include low... Medium... And high. Please visit

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.
