Mon 20 Jan Wales

This period is expected to see a transition, possibly lasting over several days, between the settled, dry, and often dull conditions expected over the next few days, to something more unsettled. Sunday itself is likely to be rather cloudy and cool, with outbreaks of rain in the west drifting slowly eastwards. The start of the following week will most likely see more settled conditions with light winds becoming re-established, with a chance of rain in both the far north and the far south, and a smaller chance that the rain could become more widespread. Later in the week, periods of much wetter and windier weather will most likely become more prevalent, from northwest to southeast, alternatively there is a very small chance of colder, drier, but perhaps wintry, easterly winds.
