In this video, it shows that our area, particularly San Jose, CA, receive thunderstorm activity! A cut-off upper level low pressure storm system was developing in the Eastern Pacific and by Friday of September 9, 2011, it made the atmosphere unstable enough for numerous thunderstorm development, especially over the Sierras.
First of all, it shows photos of the storm cell(s) that were drifting into the Bay Area region at sunset from the Northeast on the afternoon of Friday, September 9, 2011. These storms were formed over the Sierras and normally these storms move in a west to east direction. But due to the unusual, nearly stationary low, the storms were drifting at an east to west manner, like what happened here. Even numerous red flag warnings/watches were issued for the North Bay hills Friday afternoon and at around 7 p.m. they got extended to include the East Bay Hills, Diablo Range, and parts of Monterey, Santa Clara and San Benito counties due to the storms.
Then coming that same evening, at around 8-9 p.m., the thunderstorms arrived just north of San Jose, CA. As of 8 p.m., the storms were passing through Antioch, Pleasanton and Livermore areas, and heading toward Fremont, CA. In the video, the storms were already over Fremont at around this time period. Nearly constant lightning was seen from this storm cell. (some of the flashes/strikes were also slow mo'd afterwards to get a better glimpse of it). On top of that, a friend of mine said that her area experienced strong winds! It was probably caused by the possible downdrafts/downbursts from this storm cell.
While on U.S. 101 heading northbound, light rain began to fall along with more lightning flashes. You can actually see the heavy rain shafts in the distance when the lightning flashes flashed. (just ignore the talking lol) We were actually on our way to Sunset State Beach, CA for our annual church family camping trip this evening.
Then on the following day, September 10, 2011, it shows a few clips of the more developing storm clouds near the horizon, viewed from Sunset State Beach, CA. Sorry I was stuck in one spot since I didn't have my car during this time.
As September 11, 2011 came along, we were headed back home to San Jose, CA. (This day was actually the 10th year anniversary of the 9/11 tragedy). Isolated thunderstorms were still possible for our area this day. However when we went back to town, the skies were not so great, hardly any cloudage in the skies. So I decided to travel a long ways to the Central California Valleys to see the developing t-storms over the Sierras. It wasn't really impressive as I thought it would be. At least I saw decent clouds and a couple thundershowers around Merced, CA. Also it was getting late and my gas was quickly draining out again so I had to call it quits. Sometimes storm chasers have their set backs as well.
Nonetheless, there was a nice sunset I saw while headed back home. I was along highway 152 heading westbound towards Los Banos, CA when I saw the sunset.
Lastly, I added my best "snapshots" or photos of the lightning storm. Hope you enjoyed this video of another rare thunderstorm event here in California!
