Daily Forecast – Mike

High pressure aloft will weaken gradually through the upcoming weekend, allowing the marine layer to build inland, with morning low clouds and fog spreading farther into the valleys. It will be slightly cooler each day through Sunday, as the deserts remain hot. For Monday, a low pressure system will move inland, bringing greater cooling, stronger and gusty west winds over the mountains and deserts, and a chance for showers. Even isolated thunderstorms are a possibility.
