One more day of Sun, before the Rain and Cold. Friday Night Frost.

The Rip Curl Pro got off to a good start this morning at Ocean Beach in San Francisco.  The morning was cool, with just a bit of coastal fog that burned off early.  Offshore winds blew for most of the day as it warmed toward 70F.  It was another nice central coast autumn day.  Wednesday should fair about the same, and the easterly winds may persist through the entire day.  Thursday will be a day of change.

More bird action at the lagoon near Natural bridges State Park.

Models continue to project that by Thursday, we will begin to cool off and see some morning clouds.  Scattered showers and thunderstorms move from north to south across the region by the afternoon.  Rain and cold over night.  Friday will start off with showers, but coastal zones should see some clearing by afternoon.  And then a clear night is expected, allowing temperatures to drop.  Many valleys will see their first frost of the season.  If you have tender plants, you may want to get out there and protect the.  A second wave moves through on Sunday.  More cold, and possibly more rain follow next week.
