As a guess, I'll bet it was the wildlife and not the weather that was bothering them. Probably something passed that way that they didn't like the smell of. Such beautiful pictures :)
They were just slooooow today, maybe they didn't sleep well, maybe they were just feeling like we were :~D and I think that's why Cyn was spooky... she wasn't looking around her till ~ack!~ oh - it's just a log...
