This led to fears that January might bring a repeat of the freezing conditions of December. This was not to be as milder weather arrived mid-month, with temperatures climbing into double figures with a maximum of 11°C on the 15th. However, as the weather turned fine, the temperatures fell and sharp frosts returned with -5°C on the 20th, and apart from a wet day on the 25th, dry, fine weather persisted to the end of the month 4ith frosts of -4°C on 28th and 29th.
