Triple-digit heat heading our way.

Cities that could reach triple digits on Saturday include Pleasanton, Livermore, Concord, Los Gatos, Morgan Hill and Gilroy, according to weekend forecasts

The Bay Area’s first tripledigit temperature day of the summer might be right around the corner.

Following a slight warming trend from Tuesday to Thursday, temperatures are expected to soar Friday into Saturday, with many inland communities threatening to reach 100 degrees, according to the National Weather Service.

Cities that could reach triple digits on Saturday include Pleasanton, Livermore and Concord in the East Bay and Los Gatos, Morgan Hill and Gilroy in the South Bay, according to Matt Mehle, a meteorologist with the weather service.

“If we’re going to have a run at close to triple digits, it’s more likely on Saturday,” Mehle said.

The entire region will experience a slight warming trend beginning Tuesday, with temperatures ranging from 4 to 8 degrees higher than Monday, according to the weather service. Temperatures will remain above average Wednesday and Thursday, with expected highs in the mid to upper 80s across much of the Bay Area, before the heat ar-

rives Friday.

Mehle said the one “saving grace” to the weekend warm up is that overnight temperatures will drop into the 50s, providing much-needed relief.

And for those who want to escape the daytime heat?

“Head to the coast,” Mehle said, where the daytime high in Monterey is expected to be 70 degrees. “There will still be some coastal breeze coming in,” Mehle said. “It will provide relief for the immediate coastline.”
