Obviously, that question only applies to the insomniacs out there. We heard a very loud pitter-patter on our Oakland rooftop around 4 a.m., followed by some very unexpected thunder, but we weren't convinced it was weather-related until peeking out the window.
Come to find out, we weren't the only ones who witnessed this summertime rarity.
Weather experts confirmed that indeed raindrops fell through the East Bay briefly around 4 a.m. -- there was some lightening, thunder, and hail too.
Matt Mehley, a meteorologist with the National Weather Service, tells us that this random storm was due to monsoon moisture, which has blanketed the Bay Area for the last week. That's why it's felt muggy as of late.
"When you combine moisture in atmosphere with an "upper level weather flow," or a small disturbance in the atmosphere, it creates an instability, or "lift", which equals a thunderstorm. That's what led to the disturbance last night," he says.
The bout of wet weather has come and gone, so don't expect anymore late-night rain dances here. The thunderstorm is en route to the Sacramento Valley as we type.
"It's a done deal, we're seeing the tail-end of it," Mehley says.
So you can go back to conserving water.
