Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis An increased chance in showers and thunderstorms will
persist in the higher elevations of the sierra nevada each day
through Saturday due to upper-level disturbances. A low pressure
system will even bring the possibility of showers and thunderstorms
on Thursday night into Friday in the san joaquin valley, mainly
fresno county northward. Otherwise, mainly seasonal to below
average temperatures with occasional breezy to gusty conditions
are expected through Saturday. Afterward, a drying and warming
trend will begin by memorial day.

Discussion Latest satellite images show cumulus cloud buildup
over the sierra nevada with mainly clear skies elsewhere. Mainly
afternoon and evening showers and isolated thunderstorms will
continue each day, including today through at least Saturday. So
far today, and isolated thunderstorm developed just to the east
of june lake in mono county, or east of the sierra crest. However,
the possibility of shower thunderstorm development will continue,
especially later this afternoon as more cloud buildups are likely.

A more favorable pattern for instability is expected Friday as an
upper-level low pressure system moves over the region. So, shower
and thunderstorm development will become possible even over the
san joaquin valley during much of the day on Friday, including
over fresno county and northward, although the chances remain
better over the sierra due to orographical forcing. We are not
expecting a significant plume of moisture with this system, so
light showers will be the more likely scenario over the central
valley floor.

By Friday night, the upper low will be centered over central
california, including the sj valley and sierra nevada. Latest
forecast models are generally consistent in placing the low over
fresno county and move this feature eastward during the day on
Saturday. Northwest flow will set up by late Friday night into
Saturday morning behind this upper-level low and could produce low
clouds and patchy fog in the higher terrain towards frazier
park and through the grapevine. Gusty winds are possible each
afternoon and evening through the passes along the west side of
the san joaquin valley, such as through pacheco pass and
cottonwood pass along highway 41 in far northwest kern
county southwest kings county where gusts will reach around 35 to
40 mph briefly. In addition the desert areas and mountains over
eastern kern county will likely become gusty in some locales by
late Friday afternoon into the evening and again on Saturday
afternoon evening.

Some more notable model disagreement arises for the latter part
of the upcoming memorial day weekend, or by Sunday. High pressure
ridging is expected to begin building; however, some weak
disturbances behind the low and associated trough will likely
produce at least a slight chance for showers and thunderstorms
over the higher elevations of the sierra nevada. By memorial day
and through the middle of next week, the threat of afternoon
showers thunderstorms is progged to decrease in coverage but may
remain over the highest elevations. Otherwise, temperatures will
warm to above average on memorial day and Tuesday. However, this
warm-up appears brief, as another low pressure system could arrive
as early as next Wednesday, so another unsettled weather period is
possible once again during the last couple days of the month.

More details will follow regarding this next possible round of
unsettled weather as we get closer.

Aviation
Expect isolated thunderstorms with mountain obscurations over the
higher elevations of the southern sierra nevada through 03z Thursday
with a few showers possible during 03z-19z Thursday. Otherwise,
showers and isolated thunderstorms with mountain obscurations will
redevelop over the sierra nevada after 19z Thursday.VFR conditions
will prevail elsewhere across the central ca interior during the
next 24 hours.

Air quality issues
None.

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.
