A FROST ADVISORY is in effect tonight until 8AM Saturday for the inland valleys and coastal mesas. Temps there will sink into the upper 20's and low 30's for several consecutive hours...make sure your pets have someplace to take shelter from the figid temps and take a moment to protect any senstive outdoor plants.
The other three forecast zones won't fare much better under mostly clear skies as colder north westerly air pools in southern California.
Saturday will deliver mostly sunny skies and milder slightly warmer temps with Sunday following closely.
