A weak trough will move across the State today, bringing cooler weather, a deeper marine layer, and gusty west winds over the mountains and deserts. It will be warmer on Monday as winds turn offshore and the marine layer thins. The passage of another trough on Wednesday will usher in a Santa Ana pattern that will persist through the upcoming weekend with low humidity, gusty easterly winds at times, and well above average temperatures.
