220 AM PDT Sat Oct 18 2025
.DISCUSSION...Warm and dry conditions continue through the weekend
and into the early part of next week as the marine layer remains
compressed and light offshore flow continues in the higher
elevations. Humidity recoveries in the higher elevations remain
moderate to locally poor in the Santa Lucias and the interior
Central Coast mountains with good to excellent recoveries
elsewhere. A slight cooling trend begins midweek with rain chances
returning to the district for the latter part of the week.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
