Yet another Bay Area warm-up was cleared to take off Friday, and the National Weather Service said that after a weekend respite, it mostly will be a steady climb until the middle of next week.
“We have high pressure that’s expanding westward from the desert southwest,” NWS meteorologist Roger Gass said. “We still have low pressure several hundred miles off shore, but the high pressure is starting to have a larger influence.”

That influence will result in temperatures Friday climbing into the mid-to-high 90s again in the hottest inland places, while temperatures along the Bay shoreline will climb higher than the normal average, he said.
After that take off, the weather is expected to “level off” on Saturday and Sunday, Gass said.
“Then we’re going to resume a warming trend,” he said.
Such heat ups have not been unusual this year. The Bay Area endured a long heat wave around the Labor Day holiday, and endured a sizzling July.
A two-day window that will see temperatures dip 7-10 degrees from Friday is expected for Saturday and Sunday, before temperatures again start to climb Monday during a three-day march upward.
“By Tuesday of next week and probably into Wednesday, we’ll probably see 100 degrees in some places and high 90s in a lot of them,” Gass said.
On Friday, the appetizer was set to arrive.
In Alameda County, Livermore was expected to peak at 96 degrees, and Pleasanton is forecast to reach 95. In Contra Costa County, Concord is one of several cities expected to hit 96, and Walnut Creek’s high is supposed to be 95. Morgan Hill also is likely to reach 95, and San Jose is projected to reach 92.
Along the coast and near the Bay, the figures were just as telling. San Mateo is expected to reach 84, Oakland 83 and Berkeley 82. San Francisco was expected to get to 78.
“I think we used the term roller-coaster earlier this week, and that’s really what we’re seeing,” Gass said. “Again, we’re gonna expect some up and downs. There’s no offshore winds that appear to be developing, at least for right now. When we get those, that’s when it can get really hot for really long. We’re not seeing that.”
