A cold, bright and frosty start to Sunday, but cloud will probably start to edge in from the west, bringing rain, with risk of sleet and hill snow. This will tend to ease before it reaches northern and eastern areas, so here it may remain brighter. Thereafter, the weather is likely to remain changeable with further spells of rain, sleet and snow, interspersed by sunshine and showers. Winds will be brisk at times with gales around the coasts. After a cold start to February, temperatures may temporarily return closer to normal, particularly across the south, whilst northern parts are likely to remain cold. Overnight frosts are still likely to be widespread and towards the end of this period there is a greater chance of it becoming even colder.
Wednesday 13 Feb - Wednesday 27 Feb
Cold or very cold conditions are often likely to dominate the weather throughout this period, with a greater than average chance of easterly or northeasterly winds becoming established. This would bring an enhanced risk of snow, as well as widespread and occasionally severe frosts, although the exact details remain very uncertain. In this setup, the driest and brightest weather is likely in the north and northwest. Despite the prevalence of cold weather, occasional milder interludes remain possible, most likely in the south, but this poses the risk of significant snow should very cold conditions become established.
