...SCATTERED SHOWER ACTIVITY OVER CENTRAL AND SOUTHERN CA TODAY...
...LIGHT PRECIPITATION ON WEDNESDAY WITH PASSING FRONT...
...POTENTIAL FOR MORE PRECIPITATION OVER THE WEEKEND WITH SYSTEM OUT
OF GULF OF ALASKA...

.METEOROLOGICAL CONDITIONS (MON AM - SUN AM)...

The upper trough has begun shifting down the CA coast and will
spread scattered shower activity inland throughout the day today.
The base of the upper-level trough, which was previously cutoff, now
sits off the coast of Point Conception and will swing through
Southern California before cutting off again somewhere around the
southern Sierra.

Precipitation is forecast to be relatively light throughout today
with the potential for locally heavy amounts where stronger cells
initiate and track. 24-hour totals are currently highest over the
mountains of the southern Sierra and Peninsular ranges of ~.5
inches.

A brief dry period is expected on Tuesday as the upper low departs
the region before another trough swings into the Pacific Northwest
and the cold front digs far enough south to spread precipitation
across the northern portions of the forecast area. Models have
generally trended upwards over the previous several runs and are now
placing ~1 inch over the Smith basin with a few tenths over the
Shasta Drainage and up to a quarter of an inch down to the central
Sierra. No precipitation is currently forecast for the lower
elevations in the Sac Valley.

Another Dry period is expected for most of Thursday and Friday
before models begin hinting at another bout of rain Saturday into
Sunday with a digging trough out of the Gulf of Alaska. Uncertainty
is currently high as this trough cutoffs just offshore and
precipitation will be highly dependent on how close the low gets to
shore and its exact track.

Freezing levels will start the period ranging from 5k feet across
the north to ~8k feet across the far south before rising behind the
departing low. Levels are forecast to lower under the next system to
below 4k feet across the north (6k feet around I-80 corridor) while
staying above 10k feet across much of the south.
