, from the Coupled Model Intercomparison Project phase 5 (CMIP5), that have not been initialised with observations are shown in green. In all cases, the shading represents the probable range, such that the observations are expected to lie within the shading 90% of the time. The most recent forecast

is linked closely with temperature, with falls rarely occurring if the temperature is higher than 4 °C. The numbers of days with snow falling and snow lying increase with latitude and altitude, so values reflect topography. Snow is comparatively rare near sea level in Wales, but much more frequent over

to February 2006, when about 75% of the normal rainfall occurred over the area, making it the driest such period since 1932/34.

A changeable weekend lies ahead, with a mix of sunshine, showers, and shifting conditions

A changeable weekend lies ahead, with a mix of sunshine, showers, and shifting conditions from north to south. While some areas will enjoy fine weather, others may need to keep an eye on the skies. Here's what to expect as we move through Saturday and into Sunday. Saturday will bring largely
