A small low pressure tracked along the southern counties bordering the English Channel and deepened on Boxing Day bringing initially rain but this turned to wet snow. The snow clung to all surfaces breaking telegraph wires, trees etc under the weight of the snow. The snow moved away during the early hours of the 27th.
A report from Croydon.
"The snow commenced to fall a few minutes before six o'clock in the evening of the 26th. Previous to the snow fall there had been considerable rain duirng the day. It ceased snowing at 4.20am.
I calaculate from obseravtion in my garden that the average depth of snow which fell was 15 inches. The snow falling was very wet and was driven by a fierce easterly gale, so that it adhered tenaciously to all objects which it came in to contact."
12 inches of snow was reported from the higher parts of North Hampshire and south Berkshire.
Hitchin: "The heaviest fall of snow ever experienced here occurred on the 26th preceded and followed by much lightning.
