Funnel clouds are not unusual for Oregon. Tornadoes are. A funnel cloud is just a rotating cloud in the air. It can't cause any harm unless it touches the ground, then it becomes a tornado. It can be difficult to identify a funnel cloud from a still photo. It needs to be visually confirmed or else it may appear to be a low-hanging cloud. This definitely has the look and structure of a funnel cloud, however. No tornadoes have been confirmed in Oregon for the 2012 spring.
A well-timed shot was sent to us from Estacada. That looks like an impressive bolt. Notice how it goes from cloud-to-ground. These type of strikes are the only ones that produce thunder. A cloud-to-cloud lightning bolt can put a nice charge into clouds, but no thunder is heard from it.
Spring offers up some of the best weather and thus, weather photo ops. I'll be monitoring the summer photos and will be sure to share any interesting pictures!
