Updated synopsis...

Synopsis Scattered showers and isolated thunderstorms
can be expected over the higher elevations of the sierra
each day through Thursday. The threat of isolated showers or
thunderstorms will include the kern county mountains, sierra
foothills and the san joaquin valley from fresno county northward
Monday and Tuesday. Temperatures will trend cooler through
Monday then warm to slightly above normal by midweek.

Discussion The weather pattern across central california
will become more complicated during the next 48 hours as some
atmospheric energy feeds into an upper level trough and forms
a closed low over our CWA by late tonight. This low will be
a slow mover and it is not forecast to exit into southern nevada
until midday Tuesday at the earliest. Until its arrival, today's
weather will be much like yesterday across the central california
interior with mostly sunny skies, slightly lower high temperatures
and little more than a few pop up thunderstorms over the sierra.

Otherwise, an onshore flow will continue to bring marine air into
the san joaquin valley through this evening. Showers might continue
to develop over the sierra tonight as the upper level low approaches
from the northwest. Elsewhere, a good deal of mid level cloudiness
will invade the central california interior.

The atmosphere will become increasingly unstable Monday in the
vicinity of this cold core low. In turn, this means there will
likely be an uptick of showers and thunderstorms over the higher
terrain Monday through Tuesday. This not only includes the sierra,
but also the kern county mountains and desert and the foothill
regions surrounding the san joaquin valley. On the north side of
this closed low, northeast to east winds aloft may steer a few of
these showers and thunderstorms into the san joaquin valley
by Monday afternoon and evening, especially north of tulare
county and kings county. Even as the center of this low exits
east of our CWA Tuesday, wraparound moisture could still show up
as some light showers or sprinkles in the san joaquin valley
through early Tuesday evening.

The models agree on lifting this closed low out of the great
basin and into the northern rockies during midweek with some
short wave ridging aloft moving over central california Wednesday
through Thursday. Dry weather will prevail during this period
with little more than isolated afternoon thunderstorms over the
higher elevations of the sierra. There is better model agreement
now in the 5 to 7 day period. Both the ecm and GFS now forecast
another rather deep closed low to remain offshore later next week
with an eventual track toward the pacific northwest memorial day
weekend. This would leave central california under a prevailing
southwest flow aloft (ecm) or continued upper level ridging (gfs).

Both solutions suggest we will remain in a dry weather pattern
during this time.

Temperatures will continue their may zig zagging during the next
7 days. After another seasonably warm day today, high temperatures
will cool sevaral degrees below normal Monday. Tuesday through
Thursday will bring another warming trend with temperatures ending
up a few degrees above normal by Wednesday. Thursday through the
memorial day weekend will likely average slightly above normal.

In the warmest locations of the san joaquin valley and the kern
county desert, thermometer readings could top the 90-degree mark
as early as Wednesday.

Aviation
Isolated thunderstorms with local MVFR ifr conditions will occur
over the higher elevations of the southern sierra nevada between 19z
today and 03z Monday. Otherwise...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.

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.
