For what its worth the Euro puts the greatest threat for lightning in the mountains Monday afternoon. Model guidance doesn't have a consensus on the exact track of these storms but the threat is there to warrant a Red Flag Warning for a large portion of California. pic.twitter.com/DpBsZu6SUK— Drew Tuma (@DrewTumaABC7) July 17, 2021
On Thursday the National Weather Service warned the region of possible thunderstorms that could bring chances of dry lightning into the area.
As mid-level moisture makes its way across the Central Coast and Bay Area, upper-level disturbance from British Columbia will cause a lobe of energy to hit the region from the northwest, the weather service said Thursday. This might bring thunderstorms and chances of dry lightning.

The chances of dry lightning are low, but it can be a concern for starting wildfires if it strikes near dry brush throughout the region.
The weather service does not anticipate that the conditions will bring about a fire similar to the Lightning Complex fires that struck the Bay Area in August 2020.
Those fires burned hundreds of thousands of acres, destroying homes and killing at least six people.
CAL FIRE said Sunday that it's added extra staffing across units in the Bay Area in light of the expected weather conditions.

"All days off are canceled," said Robert Foxworthy, a public information officer with CAL FIRE.
That will allow them to staff up their specialty response teams to be able to quickly respond across the state.
Right now, he says their agency is only fighting one fire in the state but it has been an otherwise busy year with nearly than 5,000 fires across the state.
"Compared to last year, that's about 715 more fires and 103,000 more acres compared to where we were last year," said Foxworthy.
