The return of weather

I’ve written before about how we don’t get much in the way of weather ’round here. The pattern of boring weather was broken last Friday morning when a rare pop-up thunderstorm hit central California. Jen and I were both awakened by the sound of thunder. I first put it off as a truck or some other large thing rolling by the house. But once it happened again, I was certain that it was thunder. It’s always a nice surprise when something like this happens. And this storm was particularly surprising, as none of the weather forecasts I had seen recently predicted rain or storms. But a PG&E weather dispatched i received just before 7AM that morning confirmed the presence of actual weather:

A weak upper-level low, about 450 miles south of Diablo Canyon, continues to bring monsoon moisture towards our area.

The doppler radar at Vandenberg AFB is indicating a band of lighting and showers over northern San Barbara County moving west-northwest towards San Luis Obispo this morning. The SLO Weather lighting tracker indicates over 1,700+ strikes this morning mostly southeast of San Luis Obispo

As this band of thunderstorms moves over San Luis Obispo, it will produce mostly cloudy weather and lighting with a chance of rain showers. Precipitation amounts south of our area have been mostly light, with most of the rain evaporating before reaching the ground. (virga).

(Any spelling/grammar errors in the above block were copied over from the source.) Naturally, when there’s lightning in the sky, the smart thing to do is to stand near an open window, holding an electronic device that’s plugged into a wall outlet. And that’s exactly what I did, with the video camera. Watch for the time-lapse lightning bolt around 1:18:

The storm did produce a couple of really loud booms accompanied by bright lightning bursts (not on the video, unfortunately) but it mellowed out not long after I turned off the camera. It tried to come back strong a couple hours later, with a few boisterous thunderclaps just passed 10AM. And then it was done. That’s probably the last storm we’ll have for awhile. Still, I’m looking forward to the next one. Even if it doesn’t happen until sometime in 2009.

A rare occurrence

Last Wednesday night, we were treated to a rare thunderstorm here in central California. The weather event apparently took everyone by storm (puntastic!). I heard a weather report from a local radio station from Wednesday morning, and the meteorologist specifically said that he saw no rain in the immediate forecast. Me and Jen were eating dinner around 9:30PM when we saw the first flash of lightning. It took a noble burst of thunder to prove to us that it really was a thunderstorm. Further proof came in the form of an e-mail from PG&E, timestamped 10:16PM. The subject simply read “THUNDERSTORM WARNING,” and the body of the message appeared as follows:

Thunderstorm Warning 08/29/07

Subtropical moisture is streaming northward towards the Diablo Canyon coastline tonight. Doppler radar shows numerous thunderstorms moving north over our area. These thunderstorms are expected to continue through tonight, ending by 0400 on Thursday morning.

These thunderstorms will be accompanied by lightning, gusty winds and a chance of rain showers.

This was exciting news. I enjoy a good storm, and we usually only get one per year. The storm seemed to come in waves, where it would go strong for 20-30 minutes and then go into a lull period, only to return to its previous strength. During one of these lulls, I decided to venture out into the street to try and capture some interesting video of the storm. Unfortunately, none of my footage came out. But a YouTuber in nearby Morro Bay did get some great shots of the storm’s lightning display:
