021800z. Coast/Valleys, Marine layer clouds (based 2000-2500ft MSL) have quickly cleared out across San Diego County this morning, but will take until 1830-19z to clear out across Orange County and western portions of the Inland Empire. Low clouds redeveloping along the coast after 02z Friday, initially across San Diego County, eventually spreading into Orange County around 06-09z, and into portions of the Inland Empire around 12z. Bases will be slightly lower than this morning, around 1200-1800 ft MSL. Good confidence (80% chance) in CIGs reaching KONT by 12z with lower confidence (~40% chance) to reach KSBD between 12-16z. Similar timing and progression for cloud clearing tomorrow morning as what is occurring today.
