353 pm pdt Wed apr 25 2018

Synopsis
Mainly dry and warm this week except for a chance of a few
afternoon showers or thunderstorms in the sierra nevada.

Turning cooler and breezy on Friday and into the weekend with
increasing chances for mountain showers and thunderstorms

Discussion
Some mid level clouds in central ca. Otherwise dry and clear.

Temperature trend in the valley a bit cooler due to a deeper
marine layer along the coast and onshore flow. Otherwise a bit
warmer in the higher elevations. The slight cooling trend should
continue through tomorrow as an upper low edges closer to the N ca
coast allowing for the marine layer to deepen further. Convective
potential will be on the increase tomorrow afternoon with the s
sierra nevada in the upper level divergent flow ahead of the low.

Models show the best instability CAPE 1000+ towards the tulare
county mountains. Models are in fair agreement with a weather
system affecting ca this week. Onshore flow will be on the
increase Friday as a closed upper low moves across N ca Friday
night. This will bring additional cooling with stronger onshore
gradients across central ca. Winds should pick up Friday afternoon
with breezy to windy conditions below the mountain passes on the
west side of the san joaquin valley and the kern county mountains
and desert starting Friday evening. Breezy conditions should
continue in the sj valley Saturday as the trough axis pushes
across central ca. Windy conditions may continue across the E kern
county mountains and desert Saturday night into Sunday as the
upper level jet from the NW becomes orthogonal to the tehachapi
mountain range. Extended models prog an upper trough across much
of the west for early next week. However models having a hard
time resolving the timing of individual smaller scale
disturbances digging through the low. Models do not indicate much
in precipitation amounts. Thus any rain amounts may be light and
scattered. There is much more certainty on the temperature
forecast which will be significantly cooler than this week.

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 high.

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.
