Your milk delivery is frozen solid in the glass bottle. We have only have had a light dusting of snow much to the chagrin of the children who have been plugging for a snow day. We have had temps in the range of -8C to -10C on a couple of nights and some of the day time temps have been below 0C. It made it to 1C yesterday. At the moment we are hovering at about -2.54C and I am feeling particularly sorry for the milk man who is dropping off bottles of milk from his electric milk float. He would not be able to deliveries if we were getting the snow that Kent and Surrey is.
