Synopsis 19 301 am.

There will be showers and a slight chance of thunderstorms today.

Dry conditions are expected Monday with showers possible on
Tuesday.

Short term (tdy-tue) 19 329 am.

A cold for this time of year 540 dm upper low sits to the NW of
san francisco. A cold front is over sba county and is moving to
the east. A powerful jet streak which is very noticeable on
satellite is sweeping to the south of the area and is aimed
squarely at san diego county.

It will be a very showery morning as the front and a post frontal
trof zip through the area. Tstms are possible over vta la county
and the inner waters as the front and the jet streak interact. The
best chc of tstms will be over SRN la county and the adjacent
waters where the jet streak will be nearest.

The upper low will move to the SE and into the san joaquin vly. 500
mb temperatures drop to near -25 degrees celsius. This will
increase the instability enough to bring convective showers and a
slight chance of thunderstorms to interior sections. Rainfall
totals should range between 0.25 and 0.75 inches, except local
totals up to 1.00 inch possible across san luis obispo santa
barbara counties and near thunderstorms.

Initially, snow levels will start near 7000 feet, but will lower
rapidly behind the front, eventually lowering to between 5000 and
6000 feet during the afternoon and evening hours. A winter
weather advisory is in effect until 300 am Monday. Total snow
accumulations 1 to 3 inches between 5500 and 7000 feet, and 3 to 5
inches above 7000 feet. Southwest winds will be gusting between
35 and 50 mph across portions of the mountains, antelope valley,
and interior valleys through this evening.

Cool NW flow and a very weak ridge will move into the area in the
wake of todays front. It will lead to a decrease in clouds and dry
conditions with the only exception being the north slopes near
the kern county line where upslope flow will bring clouds and
showers. MAX temps will rise some but will still be well below
normal. There will be near advisory level winds through the i-5
corridor.

The forecast for Tuesday's system continues to evolve and now most
mdl solns are moving the upper low more to the east edging it
closer and closer to a pure inside slider. Right now it does not
look totally dry and will likely produce some instability showers
esp over the mtns. MAX temps will not change much from Monday's
readings and will remain well under seasonal norms.

Long term (wed-sat) 19 338 am.

The odd weather pattern will continue for the Wednesday through
Saturday period. Tuesdays upper low will retrograde and then spawn
an upper low which will expand to cover the state. It will then
sit and spin through the duration of the period.

The low will be centered over fresno and the flow patter will keep
any over water trajectories away from the forecast area so this
will not be a big rain maker. The cool air aloft will destabilize
the atmosphere and this combined with short waves running around
the upper low will provide for a chc of showers over the area esp
over the mtns.

Max temps will continue to range about 10 degree below normal
through the period.

Marine 19 334 am.

A cold front will move from NW to SE across the waters this
morning. There is a slight chance of thunderstorms this morning,

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.
