Yes. The police statement has was that the body had been on Longwood Lane "for several days"
There is a significant difference in elevation between the Broadmead area pictured and Longwood Lane, potentially leading to a very significant difference in snow depth. Broadmead is only 30m above sea level while Canynge Road is 70m. The entrance to the quarry on Longwood Lane is at 145m, and it sits on an east-west ridge above Long Ashton. Basically it's at the top of a steep hill. (note the 1 in 7 sign here on Providence Lane, just 200 yards from the quarry entrance...

The combination of the difference in altitude and the urban heat island effect would also mean the Ashton Estate could be significantly colder than the centre of Bristol.
I live just a couple of miles from the centre of a city but with a similar difference in elevation. I have known several inches of lying snow in my garden while the centre of the city has a rapidly melting sprinkling. Pictures of the centre of Bristol five miles from the deposition site are far from conclusive.
