Temperatures are increasing slightly Friday as heights rise. Most areas well be 3 to 6 degrees warmer, putting highs in the mid 50s to low 60s.
The front has converted more into a plume of moisture. There is still a chance of lingering spotty showers, especially on the South Coast, and there will be additional cloud cover.
An upper low west of Washington State and fall to the west of Oregon, tilting our moisture plume more northerly Friday evening. This will start to send more rain to the Central Coast Saturday.
A weak front will drag the back of the plume through the area again Sunday, creating scattered showers over the entire region through Sunday morning. The rain will taper with time.
For the entire storm, we are expecting 4 to 6 inches of rain in the very northwest corner of SLO County, 1 to 3 inches for the rest of SLO and Santa Barbara Counties, and a little less in Ventura County. There may still be snowfall at resort level.
The region will again be under dry, westerly flow Monday. The upper low will move across California through Wednesday, and temperatures will stay below average.
