The dawn glowed red this morning over Washington, D.C. This scene was captured at the Reflecting Pool. For a larger version of this photo, click here. (Kevin Ambrose)

Red sky at night, sailor’s delight. Red sky at morning, sailor take warning. There is often truth in the old adage. With today’s approaching storm system, it does ring true. I did a post last year to explain this phenomenon.

A satellite view of the storm system to the west of Washington that was captured about the same time as the photo at the top of this post. (Unisys)

The satellite image to the right shows the leading edge of the large, comma-shape cloud swirl moving towards the region just as the above photo was taken.

In our world of HDR photography and image post-processing, I should note that the top photo is untouched besides a slight cropping. I actually like HDR, but sometimes it’s helpful to know the sky’s true color at the time of a photograph.
