...SCATTERED LIGHT PRECIP SOUTH AND EAST TODAY INTO SATURDAY...
...POTENTIAL FOR A SYSTEM MOVING ACROSS NORTHERN/CENTRAL AREAS
MIDWEEK...

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

The latest setup shows an upr low spinning west of northern
Baja...in the vicinity of 30N/120W...while a secondary disturbance
is diving southeast from the Pacific Northwest to the Great Basin
through the upstream side of the broad upr trof encompassing much of
the nation this morning. Over the eastern Pacific...a narrow
wavelength upr ridge is currently situated between 130W and 140W
extending northward into the Gulf of Alaska.

Overall...look for the upr low and eventually the s/wv trof moving
toward the region from the north to generate some scattered light
precip mainly over coastal southern CA and eastern NV along with the
potential of some showers across the far southern Sierra as well.
Given the limited available moisture...amounts will be near or less
than 0.10-inch.

By the latter half of the weekend...the upr low will have shifted to
the east-northeast quickly followed by the s/wv trof swinging across
the Great Basin. In their wake...look for the upr ridge to slide
over the west coast...which will bring dry conditions to the region
for Sunday and Monday. Then by Tuesday into Wednesday...models are
struggling with a potential system moving toward the west coast.
Yesterday...the GFS was bringing precip down along the northern CA
coast for Tuesday into Wednesday...but now takes the majority of the
forcing north of the region across the Pacific Northwest with only
some rather light precip over far northwest CA. The EC and GEM are
forming a cutoff low west of the SF Bay Area that splits off from
the general upr trof...and then spreads mainly light precip across
portions of northern/central CA. Low confidence toward the end of
the forecast follows close to the latest WPC QPF and NBM...which
keeps light precip mainly along coastal sections between the CA/OR
border and Big Sur coast. Amounts at this time are near or less than
0.10-inch.
