Good morning, Central Coast! Happy Friday!

To kick off the morning there is more marine influence continuing to temper conditions across our coastal valleys and beaches.

Temps today will drop slightly, as compared to earlier this week. Still 90s are expected in the interiors. This is thanks to the offshore winds beginning to calm and thus will allow the marine layer to push farther onshore. Coastal valleys will also cool slightly most locations will be in the 60s, with a few valleys reaching 70.

This little cool down and shift in pattern is all thanks to the low pressure that has driven the offshore winds and helped to bring in some additional moisture and instability from the desert southwest. Now the low that has driven that system has pushed south into Baja California and is now directing that area of stronger offshore winds and additional moisture to the San Diego area.

Saturday will bring slightly cooler temps to the interiors as the marine layer will reach far enough inland to shave a few degrees off those high temps. It will still be warm in the upper 80s but a welcome decrease from the upper 90s that were featured to start this week. Additional minor cooling will likely take place Sunday as well.

Next week the marine influence will increase even more and in combination with a cooler air mass will drop temperatures significantly. Beach and coastal valley temperatures will drop into the 60s but the interiors will feel this change most. Highs will be in the 70s by later next week.

Have a great day and a fantastic weekend!
