Possible light rain?

NOAA forecast discussion yesterday afternoon:

The upper low will begin to move east on Friday and approach
Point Conception on Friday evening. Moisture associated with the
low will increase as flow becomes onshore. A band of light to
locally moderate rain is expected to develop over the Central
Coast late Friday and into Saturday morning. Have increased PoPs
and QPF as a majority of ECMWF and GFS ensemble members depict
this scenario. Exact placement and strength of the band is
uncertain but overall rainfall amounts will be light, with the
vast majority of rainfall confined to locations south of San
Francisco Bay.

Saturday I found these interesting statistics offered by NOAA in my forecast discussion:

One such prominent location - downtown
San Francisco - has observed rainfall records as far back as late
1849. In all that time, only one other year had no precipitation
throughout all of its February -- 1864. Looking back at the 10
driest Februarys for downtown San Francisco as a proxy ( 1864 -
0.00, 1953 -- 0.04, 1899 -- 0.10, 1852 -- 0.14, 1964 -- 0.19, 2018
-- 0.21, 1967 -- 0.22, 1995 -- 0.24, 1866 -- 0.24, 1971 -- 0.26 ),
 we can see that a dry February does not necessarily mean a dry
 March. Of these 10 year, 3 of them had a "miracle" March with
 more than 200% of normal precipitation for the month -- 1899 had
 7.61", 1852 had 6.68", and 1995 had 7.88". Furthermore, 5 of the
 10 years had above average precipitation in March after a top 10
 driest February. Currently, the long range models do look dry
 into early March, however, there is some support for a more
 progressive pattern as the month of March progresses, but it is
 too soon to say what kind of month March will be. Stay tuned
