As the ridge of high pressure that brought us the heat on Monday breaks down, we'll see some cool changes moving in this week.  On Tuesday, a good 5 to 10 degrees of cooling is expected...but even so, temperatures will remain above average.  The increasing onshore flow will bring gusty afternoon winds to the Central Coast, with breezy conditions also expected across the South Coast by the late afternoon and evening hours.

The marine layer will deepen up by mid-week as a trough of low pressure dives down the West Coast.  This will push the low clouds and fog into the valleys during the overnight and morning hours, with sunshine for the afternoon hours.  The South Coast will continue to see gusty sundowner winds during the evening hours, mostly staying confined to the foothill areas.  Temperatures will only warm into the 60s and 70s later this week, and it doesn't look like any big changes will move in for the holiday weekend.
