Unusual clouds at sunset

I was just leaving the hen guardian's house in Huntly when I spotted the strange formation of clouds. I was able to stop on the street and hope out with my phone to make a record.  The extra is tonight's moon, which is 96.9% illuminated. Full moon is on Sunday at 09:01; apparently it's called the Cold Moon, or the Long Nights Moon, or the Moon before Yule.
