Synopsis A few showers and thunderstorms remain possible
across the sierra this evening then a low pressure system will
bring an increased chance of showers and thunderstorms over the
entire forecast area this weekend, especially 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. Slight warming will
occur on Saturday then becoming 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 Another day of below normal temperatures across the
central california interior with readings right at to slightly
above this time yesterday. The region remains under a long wave
trough with east pacific ridging just nudging in along the coast.

Satellite imagery shows mostly cloudy conditions over the mountains
with scattered cumulus across the san joaquin valley and the kern
county desert. Radar is beginning to pick up a few weak echoes
over the sierra and the high resolution rapid refresh (hrrr)
model continues to indicate some isolated convection over the
mountains into this evening. Could even see a thunderstorm or two,
but the chances are low.

A short wave trough diving down over the pacific northwest will
move over california and nevada on Saturday bringing an increased
chance for showers and thunderstorms, mainly during the afternoon
and evening. While the sierra will have the best chances, showers
and storms could develop over parts of the san joaquin valley and
the mountains in kern county as well. Instability progs are higher
with pockets of sb capes over 1000 j kg. Similar temperatures are
forecast for Saturday with some areas a little warmer.

An impressive late season storm system is still expected to move
in on Sunday. Models track the moist closed upper low down the
northern california coast Sunday morning then move it right over
central california as a ~550 dm low by Sunday afternoon. In
addition, a ~130 knot upper jet is depicted with the left exit
region overhead, providing enhanced lift. So the ingredients are
there for more widespread shower activity and potentially some
strong thunderstorms. But the monkey wrench in the ointment for
thunderstorm development may be if extensive cloud cover limits
surface heating. Thunderstorms would be capable of producing small
hail, gusty winds, and locally heavy rainfall. Cannot rule out the
possibility of funnel clouds or even a weak tornado. Snowfall may
be heavy in parts of the sierra nevada on Sunday. A winter storm
watch has been issued for a portion of the sierra above 6000 feet
from 5 am Sunday through 5 am Monday. Current estimates call for
4 to 8 inches of snowfall above 6000 feet with amounts to around
12 inches above 7000 feet. Temperatures will lower significantly
on Sunday to well, well below normal for late may. The forecast
high for fresno is 62 on Sunday, 25 degrees below the climatological
normal of 87. In fact, we could set new record lowest maximum
temperatures for the date in some areas. The record low MAX for
fresno on may 26 is 66 degrees with the forecast of 62, and the
record low MAX for bakersfield is 68 degrees with a forecast of
67.

The low should shift east over nevada on Monday with scattered
showers limited to the sierra once again. A general troughiness is
expected to continue over the region next week but gradual warming
will bring temperatures up to near seasonable levels by late in
the week, which is mid upper 80s across the sjv and desert areas.

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.
