There are a lot of things I'm not, and one of those is a meteorologist. My forecasting 'expertise' is limited to knowing a few phrases such as 'red sky at night, sailor's delight' and 'red sky in the morning, sailors take warning'. If there's no red sky at all, I have to turn on the TV or radio to find out.
Real weather forecasters of course have all sorts of modern technical tools to help them make their predictions. But in the days before all this wonderful technology, observant people would watch the sky for signs of pending weather, hence the origin of these folk wisdoms. This afternoon, armed with the knowledge of a pending cold front, we went for a walk with friends while the weather was still cooperative. One of the first signs we noticed of a 'change in the air' was the rapid change from a bright blue sky to the cloud formation below. We managed to get our walk in before these clouds gave way to much darker clouds, accompanied by a driving rain, gusty winds, and much cooler weather.
I did a little research early this evening, and I think these are altocumulus clouds (remember what I'm not). I stand to be corrected by a real expert out there. At any rate, I find clouds to be fascinating harbingers of weather to come.

I'm trying to regularly participate in Scott's Sunset Sunday so here's one of the sunset photos I made on our recent dinner cruise:
