January was slightly drier than average for the UK as a whole (91%), with a few localised exceptions in some coastal areas and Northern Ireland. February was also dry (68%). There was a period of widespread snowfall across much of the country from mid to late January as frontal systems hit colder air, causing considerable disruption.
