While temps have cooled slightly near the coast and inner bay, inland areas are still expected to soar into the 90s, with peak temps in the 100s again farther north into Lake and Mendocino Counties and parts of Solano County as well.
We should begin to see some cooling for inland areas on Sunday as onshore wind picks up and low clouds begin to fill in along the coast and push locally inland again during the early morning hours early next week. Notably cooler temps will settle in from Monday to Wednesday.
A Spare the Air alert is in effect for Saturday with some areas of smoke at times from the Willow Fire likely to move north into the Bay Area.
With triple-digit temperatures forecast through much of the region, the Bay Area Air Quality Management District on Friday extended a Spare the Air alert through Saturday because of excessive levels of smog expected.
The air district issues a Spare the Air day when weather conditions, like Thursday's forecast of light winds and unusually hot temperatures, will combine with vehicle exhaust to make an excessive amount of smog. Friday's forecast will be much of the same.

Friday's Spare the Air alert will be the third of the season. On Spare the Air days, drivers are encouraged to find alternatives to driving alone to work or other destinations to limit the number of vehicles on the road.
Young children, seniors and people with respiratory and heart conditions should also avoid prolonged exposure to smog, and outdoor exercise should only take place in the early morning when concentrations are lower, air district officials said.
