Unstable Sky
When I looked out this morning around 6:15 AM at the beautiful sunrise, I could see it. The potential for showers and thunderstorms was there.

Below are images from the Space Needle Pano cam at 6:10 and 6:20 AM. Not only was the sunset beautiful, but the colors changed radically in ten minutes from red to yellow.

But look at the clouds. There is a deck of mid-level clouds that are broken into lots of puffy, individual elements. This is sign of instability--the tendency to convect--in the middle atmosphere. And often precedes convection (e.g., thunderstorms) in our area.

Forecast is for cooler weather for the next week or so.
