Shortly after waking up this morning, I looked outside and had a feeling there was going to be a good sunrise.
For spectacular sunrises, you need a fairly clear sky but not one that is completely empty of all clouds. So many sunrises here in the Pacific Northwest are completely hidden by thick cloud cover, but a few wispy clouds will light up with the sun at its lowest level on the horizon.
As the sun gets closer to breaking the horizon, most of the pink color will wash out of the sky, but the contrast between yellow and blue will intensify. Below is a shot immediately before the sun rose over the top of the Cascade Mountains. (15-Dec-2013: I guess I lost it. I can’t find this image. I’ll keep looking though. For now, here’s a picture of a different sunrise.)
