Any idea why this storm wasn't forecast? TV weather people didn't mention this yesterday morning and my phone didn't show anything other than clouds for the day even after the storm started.

Most people I have spoken with were completely unprepared for this, out on bikes and walking without umbrellas. Lots of stories around the water coolers today!

It was forecast during the preceding several days by the National Weather Service. Tell your TV weather "forecaster" and your phone to consult them. Or check for yourself at

How did anyone calculate the number of bolts and strikes? Is making up numbers the same as calculating?

@Incalculable - Technology. Thing that weren't calculable or countable become so. NWS gets lightning data from the National Lightning Detection Network, and NOAA’s recently launched GOES-16 Lightning Mapper satellite.

My husband biked home to Palo Alto from his job in San Jose in that storm. He arrived soaked, but he said the "light show" was spectacular.

The computer models were quite divergent so the weather bureau was reasonably cautious in their forecasts, but they did forecast a slight chance of thundershowers several days prior to the event.
