Synopsis
Generally light sierra showers and isolated afternoon thunderstorms
next couple of days as an upper low liners over the great basin.

Mainly dry elsewhere next couple of days with near normal
temperatures. Showers and isolated thunderstorms Friday through
memorial day as another low drops out of western canada.

Discussion
The upper level low which brought snow and thunderstorms yesterday
is currently centered over southern california. Mostly sunny
skies with some high and mid clouds are present across most of the
area. Temperatures are 5 to 18 degrees warmer than yesterday,
though will remain below normal for this time of year. Isolated
light showers are starting to develop over the sierra and
foothills. There could be enough instability for a few
afternoon evening thunderstorms to form over the mountains and
foothills.

Upper troughing over the great basin with northeasterly flow will
continue the shower and thunderstorm threat over the sierra
cascade range and foothills on Thursday. The airmass warms
slightly so should see a little warm up to slightly below normal
high temperatures for this time of year. Breezy northerly winds
are expected during the day, gusting up to 20 to 30 mph over the
northern and central sacramento valley.

Another upper low drops southward out of western canada Thursday
night will nudge the great basin low eastward bringing a temporary
dry period Thursday night and Friday morning. This break will be
short lived however with the upper low approaching norcal with a
threat of showers or thunderstorms for the mountains and the
northern sacramento valley by Friday afternoon. Daytime highs
will cool slightly on Friday then much more on Saturday as the
upper low continues southward through northern california. This
low will bring showers and afternoon isolated evening
thunderstorms to most of the area. Anyone planning weekend outdoor
activities should be prepared for periods of wet weather and
should be prepared to take shelter if thunderstorms develop. Daytime
highs are expected to drop to 10 to 15 degrees below normal, which
is the low 70s for the valley and delta. Ek
.Extended discussion (Sunday through Wednesday)
a closed upper low will be tracking across california towards the
southwest CONUS Sunday into Monday. Ensembles have been
consistent in indicating the potential for precipitation both on
Sunday and Monday. The better chances for showers and storms look
to be in the foothill and mountain regions Sunday, although light
valley rain will still be possible. Models indicate some
instability mainly north of i-80 across the area and have kept the
mention for scattered thunder on Sunday afternoon. Lingering
precipitation will be seen on memorial day. Models have a bit less
instability this day and have left the mention of thunder out at
this time. From here, dry valley conditions should be seen through
mid week with small precipitation chances at higher elevations.

Temperatures will be back on the rise Sunday through Wednesday,
with valley highs back into the 80s by Wednesday afternoon.

Aviation
"backwash" cloudiness will be spreading swward over norcal as
upper low moves from socal neward into utah. Most of norcal will
remainVFR, however local MVFR conditions in showers and isolated
thunderstorms can be expected over the W slope sierra with higher
terrain obscured. Lesser chance of a shower storm over the coastal
range. Areas of nly surface wind gusts up to 30 kts possible in
the vly through 03z thu, and over the west side of the vly
overnite. Local NE to E winds over the sierra gusting to 45 kts
overnite.

Sto watches warnings advisories
None.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
