It was sunny in the NW, but dull on the south coast. Particularly wet in the SW. A very mild, wet, stormy first half; the first week was the warmest since 1986, and the first half since 1979. 15C widely recorded on the 5th (Leeds), 11th, and 13th. The last week brought Arctic air which partly offset the earlier mild weather; the cold spell was the most notable and widespread since that of 1995. -14C was recorded at Hereford on the 29th and -15C at Dalmally (Argyll) on the 30th - the lowest UK reading since January 1997. Most of the country saw some snow, with the 27-29th being the main snowfall event of the year. The M40 was closed for a time near Oxford. Parts of the Home Counties saw the deepest snow since February 1991, with 20 cm at Luton airport.
