Synopsis High pressure will continue to bring a warming trend
the next couple of days then little changes through midweek. Dry
conditions will prevail though there is a slight chance of a few
showers and thunderstorms along the sierra crest Tuesday through
the end of the week.

Discussion Satellite imagery shows a weak upper low spinning
just off the coast of northern baja ca and spreading a few high
clouds over central ca. These clouds are on the decrease as the
low is shifting inland. A weak S WV trough off the pac NW coast
will move inland this afternoon and could spread some more high
clouds across the region. Regardless, cloud cover should be not
be sufficient to inhibit warming. Temperatures are forecast to
nudge a little higher both today and Monday resulting in highs
around 10-15 degrees above climatological norms for late april.

Little changes in temperatures are expected through midweek as
an upper low drops down offshore of the west coast and an upper
ridge remains over the western conus. Slight chance pops remain
over the sierra crest beginning Tuesday as isolated showers and
thunderstorms could develop with daytime heating.

There remains a fair amount of uncertainty regarding the track
of the offshore low. 24 hours ago, the GFS had trended towards
the ECMWF idea of lifting it NE towards the pac NW coast later
in the week. But the last couple of runs have reverted back to
moving it inland over central ca late Friday into Saturday. The
gem is somewhat of a compromise as it tracks the low inland over
northern ca. So lots to be determined still as there could just
be a modest cooling trend with dry weather continuing or a more
significant cooling trend with precipitation chances. Have kept
cooling trend Thursday and Friday with temperatures lowering to
near climo again. Nudged pops a bit higher and increased areal
coverage Friday night and Saturday, but chances are still low.

Onshore surface pressure gradient will increase late in the week
for breezy to gusty conditions, mainly in around mountain passes.

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

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.
