...SHOWERS CONTINUE TODAY AND FRIDAY...
...SOMEWHAT WARMER AND DRIER INTO NEXT WEEK...

.METEOROLOGICAL CONDITIONS (THU AM - WED AM)...

The upr low situated in the vicinity of Point Conception over the
past couple days is beginning to slowly make its way to the east as
an open s/wv trof...and is expected to phase with a s/wv trof
dropping southward through the interior of the Pacific Northwest
toward the Great Basin. This will bring another day of showers and
possible t-storms over the central/southern Sierra along with light
precip across coastal southern CA and southern/eastern NV. Then with
upr troffing remaining in place across the Great Basin and Rocky
Mountain states...with cyclonic northerly flow over CA and NV there
may be one last day of scattered showers over the southern Sierra
down over portions of coastal southern CA and points east over
southern/eastern NV.

General ridging will move overhead on Saturday...but will not be
overly strong as weaker disturbances move through the westerly flow
aloft toward the Pacific Northwest...potentially clipping the
northern part of the area with a few light showers possible.
Temperatures should rebound to about plus 5- to plus 10-degF above
seasonal normals.
