Cooler, more seasonable weather returns to San Francisco as temperatures drop to around normal through the weekend and into this week.
AccuWeather.com Meteorologist Erik Pindrock said a noticeable cool down will be felt later in the weekend.
Temperatures soared into the 80s and 90s during midweek, high above the average temperatures of high 60s.
"The worst of the heat will end this weekend," he said. "There will be a noticeable Pacific influence bringing those lower temperatures."
Lower temperatures will make a nice weekend for weekend activities.
Through Sunday and early this week, San Francisco will see some low hanging clouds in the morning that will give way to afternoon sun. Due to low clouds, there may be spotty flight delays at San Francisco International Airport in the early morning hours, he said.
By Sunday, temperatures will sink below the 70 degree F mark, giving way to temperatures in the mid-60s.
"Looking ahead into early this week, temperatures should stay around the mid-60s with partly sunny skies," he said.
