High pressure will nudge in from the southwest as we head into the weekend, which will lead to slight warmup and a decrease in low clouds. The ridge will shift back east out of the weekend as a trough of low pressure digs down the West Coast. The initial trough will move into the Pacific Northwest, but a second area of low pressure will develop off the California coast and help enhance a period of cooler, cloudier weather for the area next week.
Sunday: Mostly cloudy early, then becoming mostly sunny on the coast and sunny inland. Coastal highs in the mid-60s to mid-70s and low 80s to around 104ºF inland. Breezy at times in the afternoon.
Overnight: Low clouds slowly thicken after dark, filling in around the bay and eventually into nearby valleys. Patchy fog. Expect coastal lows in the mid-50s with low to mid-50s inland.
Extended: Temperatures will begin to cool out of the weekend as a trough of low pressure develops on the coast. Highs will be below normal by Tuesday and will likely remain that way through the end of the week. You can also expect an increase in low clouds.
