A high-pressure system is starting to expand over the state, which will bring a shift to the weather pattern. First, daytime highs will gradually warm up through the end of the week. In some areas, like the interior valleys, daytime highs are expected to reach triple digits. Second, the marine layer will simultaneously shrink allowing for more sunshine through the afternoon hours.
For Tuesday, temperatures along the coast will mostly be close to the mid to upper 60s with potential for widespread fog throughout the late morning. For the coastal valleys, temperatures will stay close to the low 70s with partly cloudy skies. Further inland, the interior valleys will be around the low to upper 80s with mostly clear skies.
The wind forecast looks to be calm Tuesday, but conditions will change by the end of the week. Afternoon northwesterly winds will increase Thursday through Saturday and range from 15-30 miles per hour.
