A mix of low (mainly over the Pacific), mid, and high level clouds are seen via satellite imagery early this afternoon. However, where low clouds were slower to clear late this morning, we could see temperatures not reach their forecast maximum temperatures. This is especially so over the North Bay. We are still forecasting mid 60s to lower 70s across the interior with upper 50s to mid 60s in coastal areas this afternoon as low clouds continue to dissipate.
A cut-off mid/upper level low pressure is forecast to develop off of the Bay Area and northern Central Coast tonight and gradually shift inland across the Central Coast on Sunday. This will likely result in drizzle and/or light rain across much of the Bay Area and northern Central Coast through the weekend. Rainfall amounts are forecast to be light, generally a few hundredths of an inch or so through Sunday afternoon. The greatest potential to see greater than 0.10" will be across the Santa Cruz Mountains and the Santa Lucia Range due to orographic lift along the coastal slopes. While rainfall amounts are forecast to be light, slick roadways are anticipated this weekend.
In addition to the drizzle/light rain potential, cooler temperatures are also forecast for the weekend with afternoon highs up to 10 degrees below seasonal averages. On the flip side, increased cloud cover will result in overnight/morning lows up to a few degrees above normal.

Drier conditions are expected for Monday through next weekend with a gradual warming trend through the period. However, general troughing across the region will limit any type of significant warm up with interior areas warming into the mid 70s by Thursday afternoon. Meanwhile, coastal areas will remain in the upper 50s to 60s. The 6- 10 Day Temperature Outlook from the CPC indicates the warming trend.

VFR-MVFR conditions continue tonight and Saturday. A few areas of light drizzle develop tonight and Saturday morning. A low pressure system will be nearby Saturday with a mix of light drizzle, light rain and rapid cooling aloft may result in showers. It's somewhat of a complex forecast in the nearest term since the 500 mb low will be strengthening as it moves eastward through a long wave trough that extends from CA/NV/AZ to MT/WY. Across the north Central Coast showers may become moderate to heavy Saturday afternoon and evening.
Vicinity of SFO, VFR. A few showers developing Saturday afternoon through Saturday night. West wind diminishing to 5 to 12 knots tonight through Saturday.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, VFR-MVFR. Light coastal drizzle develops tonight and Saturday morning. Showers also developing Saturday with a low pressure system nearby. Showers may become moderate to heavy in the afternoon and evening. Mainly west to southwest winds near 10 knots. It is possible a southeasterly wind develops in the Salinas Valley if surface pressures lower more than current model forecasts.
