Synopsis
A low pressure system will bring an increased chance of showers
and thunderstorms over our area today, and possibly on Sunday.

Some thunderstorms could become strong with small hail, gusty
winds, and locally heavy rainfall possible. Several inches of
snowfall is forecast over parts of the sierra nevada. Temperatures
will become significantly cooler on Sunday. A warming trend is
expected next week with a few afternoon and evening showers
possible over the sierra nevada each day.

Discussion
Convection is already firing up across cencal attm. Models are
advertising capes around 1500 j kg and li's 0 to -2 over the sjv
today. An upper level trough is pushing through the region
in advance of a strong area low pressure that will be crossing
the area tomorrow. More seasonal high temperatures today with
possible record low maximum temperatures forecast for tomorrow.

Eventhough tomorrow the calendar says may 26th... Its going to
feel more like february 25th! Forecast highs are expected to be in
the low 60 across the sjv on Sunday. Which has put a damper on
many memorial day plans. A very impressive 546 dm upper low
center is forecast to cross the region on Sunday with plenty of
clouds and precip expected. High elevation snow is also in the
forecast and will create travel issues for folks planning a trip
to the national parks in the southern sierra nevada. Model
guidance is coming in a bit wetter today than last nights model
run and we have bumped up amounts a few inches. At this point the
advisory is out and we are concerned about travelers going to the
mountains tomorrow. Snow will spread across the region Sunday
morning and continue during the day on Sunday becoming heavy at
times. Travel is highly discouraged into the mountains.

So how cold is going to get tomorrow?
here are some record low MAX temperatures for area cities for may
26...

hanford 70 1998
madera 73 2011
merced 73 2012
we are currently forecasting 60 to 65 across most areas in the
sjv. So records are in jeopardy tomorrow.

Rainfall amounts are pretty decent as well as new guidance is
giving the sjv 0.10 to 0.50, sierra foothills and mountains 0.50
to 1.00 and below the snow line. We are looking at the snow line
to start out around 7000 feet and lower through the day on Sunday
to around 5500 feet late on Sunday evening. Snow amounts have
increased a bit since last nights run and forecast package. We are
now looking at 3 to 7 inches and isolated amounts possibly 10 to
even 12 inches.

The upper low center will move into SRN nv early Monday with
gradual clearing conditions across the sjv region. The mountains
will remain unsettled through the week as broad cyclonic flow will
swing impulses through the sierra and trigger afternoon and
evening convection. Wednesday is indicating a stronger impulse
moving across the rejoin that will trigger more widespread
mountain precipitation. Convection will become less widespread
late int eh week and into the weekend in the sierra.

Aviation
MVFR conditions can be expected over the sierra during the next 24
hours with areas of ifr and mountain obscurations. Additionally...

isolated thunderstorms are possible over the sierra and adjacent
foothills until 03z Sunday. A recurrence of isolated thunderstorms
is possible over the central california interior with local
MVFR ceilings between 19z Sunday and 00z Monday.VFR conditions
can be expected elsewhere over the central california 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.

Certainty levels include low... Medium... And high. Please visit

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.
