Tonight a weak warm front brings a patchy light rain and some mist and murk. It will be generally mild and muggy, but temperatures could drift down to 8C.
That warm front draws more warm air in across Wales for Saturday but continues to feed a lot of cloud and some patchy rain in. It's likely to be a misty murky start for some. In to the afternoon the mist should lift but it's likely to remain cloudy with any brighter spells expected further east.
Being a warm front, we have warm air drifting into Wales so we can expect it to be unusually warm for the time of year, in spite of the lack of sunshine. Highs of 19C but feeling rather humid.
Sunday sees the weather brightening up a little form much of Wales. There could, however, be the odd shower around. Monday and Tuesday should be brighter still with more sunny spells around, before more cloud arrives midweek.
