Much cooler than Saturday, as much as 12 to 18 degrees cooler for the mountains and deserts. Highs for the coast and valleys mostly in the 60s, in the mid 50s to lower 60s for the Apple and Lucerne Valleys, in the mid 70s to lower 80s for the lower deserts, and in the 40s and lower 50s for the mountains for elevations from 4500 to 7000 feet.
