281200Z...Coast/Valleys/Coastal Mountain Slopes...VFR conditions prevail early this morning, with cloud based varying between 2500- 6000ft. More BKN-OVC clouds at 5000-6000ft MSL can be found along and adjacent to the coastal mountain slopes with FEW-SCT clouds at 2500-3500 filtering in and out for the coasts/valleys. Very sparse DZ/-RA remains possible (<10% chance) until around 14z Thurs. Should any instances of this occur near terminals, brief CIGs near 2500- 3500ft may accompany them. Mostly clear skies expected through the afternoon today, with perhaps FEW Cu ~5000ft MSL. A very similar set up of cloud cover returns by 03z Fri, with clouds near 5000ft up against the higher terrain, and FEW-SCT clouds 2500-3500ft for the coasts/valleys. DZ/-RA is possible again between 06-18z Fri, though chances will be a little higher than tonight, closer to 20-30%.
