Synopsis An area of low pressure will remain anchored off the
southern california coast through Tuesday and bring a chance of
mainly afternoon showers and thunderstorms to the sierra. The
threat of thunderstorms will extend into the kern county mountains
and desert and the sierra foothills by early next week with the
arrival of monsoonal moisture.

Discussion Some mid level clouds remain over the district from
afternoon convective activity. Otherwise clear skies prevailing
this morning. Temperatures running cooler across the central
valley due to a deeper marine layer along coast. Otherwise little
change elsewhere. Thunderstorms occurred over the sierra nevada
and kern mountains and expect a repeat of thunderstorm activity
for Sunday afternoon and evening. Conditions remain conditional
unstable with little change in airmass and precipitable water
values up to 120 percent above normal over central ca. Water
vapor imagery show an upper trough off the ca coast developing
southward. This feature will provide favorable conditions for
continued convective forcing with the afternoon wind convergence
over the mountains.

Models in agreement that the trough will remain off the
ca coast through Tuesday. Another upper disturbance will move
south into the trough retrograding the trough further offshore.

This will maintain an east to southeast mid level flow tapping
into some deeper monsoonal moisture over arizona and northern
mexico. Models show the moisture will begin to infiltrate the kern
county mountains and desert by late Sunday night and advect
northward up the sierra during the day Monday. This area will
become the primary focus for more widespread showers and
thunderstorms early next week. The GFS models indicate a moderate
e to SE flow Monday night and Tuesday as the low closes off point
conception. This could bring the convective storms into the into
the foothills or the east side and south end of the san joaquin
valley.

The models forecast the trough to weaken as it moves onshore over
s ca Wednesday. A westerly flow aloft should bring drier and
stable conditions Thursday. A warm and dry trend expected
thereafter as an upper level ridge builds northwestward from
texas.

Aviation
Isolated to scattered thunderstorms over mountains after 20z this
afternoon and extending into desert areas after 06z tonight.

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.
