Bay Area communities are in store for another hot day Friday before a weekend cool-down.
While inland areas will still be hot with highs in the 90s to around 100 degrees, a redeveloping marine layer will help to cool coastal areas Friday night, according to the National Weather Service.
The cooling trend will peak into the weekend, with below normal temperatures forecast across the region through Sunday, the NWS said. A deeper marine layer should return Saturday night into Sunday helping to cool a broader area.
The Bay Area Air Quality Management District issued another Spare the Air alert for Friday. Spare the Air alerts are issued when ozone pollution is forecast to reach unhealthy levels.
"One more day of heat and smog just underscores how urgent it is that Bay Area residents get out of their cars, use public transit, try a carpool and find other way to get to work," said Jack Broadbent of the Air District.
"Tailpipe exhaust is the largest source of air pollution during warmer months and reducing our daily driving will make the air healthier for us all," Broadbent said.
